description: In einem Rechtsstaat werden amtliche Statistiken grundsätzlich von neutralen Stellen errechnet. Im Gegensatz dazu unterliegt der Mietspiegel trotz seiner hohen Bedeutung für den Wohnungsmarkt zu einem großen Teil dem Gestaltungswillen lokaler Politiker und Interessensvertreter. Der Prozess seiner Erstellung bleibt zudem weitgehend intransparent. Im Ergebnis sind die durch Mietspiegel ausgewiesenen ortsüblichen Vergleichsmieten deutlich niedriger, als sie es nach aktuellen Marktbedingungen sein müssten. Dies widerspricht grundlegenden Prinzipien für amtliche Statistiken eines Rechtsstaates. Sofern eine Begrenzung der Miethöhe politisch erwünscht ist, sollte diese getrennt von der Erstellung des Mietspiegels umgesetzt werden. Um die Funktionsfähigkeit des Wohnungsmarktes aufrecht zu erhalten, muss der Mietspiegel wieder zu einem marktnahen Abbild des tatsächlichen Preisgefüges werden. Lerbs und Sebastian zeigen auf, welche Praktiken bei der Erstellung von Mietspiegeln zu einer Verzerrung der ortsüblichen Vergleichsmiete führen und wie dies zukünftig verbessert werden können. Nur zum Teil ist dazu eine Änderung der aktuellen Rechtslage erforderlich.

description: Was muss ein Unternehmen heutzutage leisten um auf Dauer mit dem Wettbewerb mithalten und den Veränderungen von Industrie und Gesellschaft standzuhalten? Was bedeuten die einzelnen Buzz-Wörter wie „Industrie 4.0“, „Internet of Things“ und „Cyber-Physikalisches Produktionssystem“ konkret für die eigene Situation? Die folgende Arbeit versucht, diesen Fragen nachzugehen. Konkret wird hierfür das Beispiel der Messtechnik Branche untersucht und versucht, für die Software des Mitutoyo Konzerns eine Softwarearchitektur zu entwickeln, welche für die neuen Entwicklungen gewappnet ist. Hierfür wird zunächst eine grundlegende Untersuchung der aktuellen Trends in der Industrie durchgeführt und daraus Anforderungen abgeleitet. Dann werden die einzelnen Aspekte auf die Architektur übertragen und eine grundlegende Basisstruktur definiert. Anhand des konkreten Beispiels einer Software zur Status Überwachung und Auslastungsplanung für Messmaschinen wird dann untersucht, inwiefern die Basis Architektur den ermittelten Anforderungen gerecht wird.
description: What does a company have to do in the current time to keep up with the competition and to withstand the changes of industry and society? What do the individual buzz words such as "Industry 4.0", "Internet of Things" and "Cyber-Physical Production System" mean when projected onto their situation? The following thesis tries to find an answer to these questions. For this the specific example of the metrology industry is examined and it is attempted to develop a software architecture for the software of the Mitutoyo Group ready to face these new developments. A fundamental examination of the current trends in the industry is done to accomplish this and requirements are derived from it. Afterwards the individual aspects are transferred to the architecture and a fundamental base structure is defined. Based on the concrete example of a software for status monitoring and capacity planning of measurement machines it is then examined to what extent the basic architecture meets the previously determined requirements.

description: We study the single-orbital Hubbard model on the 1/5-depleted square lattice geometry, which arises in such diverse systems as the spin-gap magnetic insulator CaV4O9 and ordered-vacancy iron selenides, presenting new issues regarding the origin of both magnetic ordering and superconductivity in these materials. We find a rich phase diagram that includes a plaquette singlet phase, a dimer singlet phase, a Neel and a block-spin antiferromagnetic phase, and stripe phases. Quantum Monte Carlo simulations show that the dominant pairing correlations at half filling change character from d-wave in the plaquette phase to extended s-wave upon transition to the Neel phase. These findings have intriguing connections to iron-based superconductors, and suggest that some physics of multiorbital systems can be captured by a single-orbital model at different dopings.

description: In the standard model, the Higgs boson $h$ couples to the quarks and charged leptons according to the well-known formula $(m_ψ/v) h \barψψ$, where $ψ$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value. Suppose $m_ψ$ is of radiative origin instead, then the effective $h \barψψ$ Yukawa coupling will not be exactly $m_ψ/v$. We show for the first time quantitatively how this may shift the observed branching fraction of $h \to \bar{b}b$ and $h \to τ^+ τ^-$ upward or downward. Thus the precision measurements of Higgs decay to fermions at the Large Hadron Collider, due to resume operation in 2015, could be the key to possible new physics.

description: We study local CP-violation on the lattice by measuring the local correlation between the topological charge density and the electric dipole moment of quarks, induced by a constant external magnetic field. This correlator is found to increase linearly with the external field, with the coefficient of proportionality depending only weakly on temperature. Results are obtained on lattices with various spacings, and are extrapolated to the continuum limit after the renormalization of the observables is carried out. This renormalization utilizes the gradient flow for the quark and gluon fields. Our findings suggest that the strength of local CP-violation in QCD with physical quark masses is about an order of magnitude smaller than a model prediction based on nearly massless quarks in domains of constant gluon backgrounds with topological charge. We also show numerical evidence that the observed local CP-violation correlates with spatially extended electric dipole structures in the QCD vacuum.

description: We present a derivation that maps the original problem of a many body open quantum system (OQS) coupled to a harmonic oscillator reservoir into that of a many body OQS coupled to a lattice of harmonic oscillators. The present method is particularly suitable to analyse the dynamics of atoms arranged in a periodic structure and coupled the EM field within a photonic crystal. It allows to solve the dynamics of a many body OQS with methods alternative to the commonly used master, stochastic Schrödinger and Heisenberg equations, and thus to reach regimes well beyond the weak coupling and Born-Markov approximations.

description: Recent progress in preparing well controlled 2D van der Waals heterojunctions has opened up a new frontier in materials physics. In this paper we address the intriguing energy gaps that are sometimes observed when a graphene sheet is placed on a hexagonal boron nitride substrate, demonstrating that they are produced by an interesting interplay between structural and electronic properties, including electronic many-body exchange interactions. Our theory is able to explain the observed gap behavior by accounting first for the structural relaxation of graphene's carbon atoms when placed on a boron nitride substrate and then for the influence of the substrate on low-energy $π$-electrons located at relaxed carbon atom sites. The methods we employ can be applied to many other van der Waals heterojunctions.

description: We carefully re-examine the conditions of validity for the consistent derivation of the Lifshitz-Matsubara sum formula for the Casimir pressure between metallic plane mirrors. We recover the usual expression for the lossy Drude model, but not for the lossless plasma model. We give an interpretation of this new result in terms of the modes associated with the Foucault currents which play a role in the limit of vanishing losses, in contrast to common expectations.

THE DESIGN, SYNTHESIS, AND APPLICATION OF A REFINED PHOTO-SWITCHABLE CYCLIC PEPTIDE SCAFFOLD FOR ΒETA-TURN MANIPULATION

description: The concept of manipulating secondary structure has been a powerful method to alter chemical processes and interactions. One of the most recent avenues used in achieving this goal is the field of photopharmacology. The use of light to activate and control chemical processes has been extensively studied for this purpose. It was proposed in Chmielewski group that a cyclic peptide containing a azobenzene-like amino acid could be used to modulate a peptide conformation, into a β-turn. This first-generation macrocycle, FLAp, consisting of four alanine residues split by the azobenzene amino acid and a test β-turn sequence (Asn-Pro-Gly-Gly) showed type II β-turn conformation in the cis form, but no turn in the trans. This result, although promising, showed only a two-fold difference in inhibition of somatostatin receptor when using the somatostatin β-turn sequence (Phe-Trp-Lys-Thr). This small difference in activity was attributed to the flexibility of the macrocycle in the two conformations. Efforts have been made to create a better, more rigid scaffold than that used with FLAp to allow for improved differences between the two conformations of the azobenzene. The FLAp cyclic peptide was altered by only having one alanine residue on either side of the azobenzene to create TAp, for increased rigidity. A second peptide, TApβ, was synthesized using β-alanine residues in place of alanine, for added flexibility within the peptide. The TAp and TApβ peptides were shown to possess type II and type II’ β-turn properties respectively, supported by 2D NOESY NMR and restrained molecular dynamics. The trans isomer of TAp, however showed a kink in the peptide backbone, while the TApβ peptide showed a linear backbone with no kink. With the scaffold of TApβ shown to be optimum for structural distinction between the cis and trans conformations. This sequence was carried forward for biological testing. As a proof of concept, the β-turn of tendamistat (Ser-Trp-Arg-Tyr) was chosen, for its hydrophilicity and its target α-amylase. The resulting peptide tendamistat β (TSβ) was synthesized and compared against its linear form (L-TSβ), as well as a literature control (Bartlett control). The cis conformation of the cyclic peptide TSβ showed lesser activity than its trans counterpart, as well as its linear cis and trans counterpart, against α-amylase. Due to unexpected results it was deemed that tendamistat was not suitable for use within the TApβ scaffold because of conformational restriction of the tendamistat sequence. This may be due to the type I β-turn of tendamistat where Tapβ induces type II’ β-turn formation.

description: A quantum isolated horizon can be modeled by an SU(2) Chern-Simons theory on a punctured 2-sphere. We show how a local 2-dimensional conformal symmetry arises at each puncture inducing an infinite set of new observables localized at the horizon which satisfy a Kac-Moody algebra. By means of the isolated horizon boundary conditions, we represent the gravitational fluxes degrees of freedom in terms of the zero modes of the Kac-Moody algebra defined on the boundary of a punctured disk. In this way, our construction encodes a precise notion of CFT/gravity correspondence. The higher modes in the algebra represent new nongeometric charges which can be represented in terms of free matter field degrees of freedom. When computing the CFT partition function of the system, these new states induce an extra degeneracy factor, representing the density of horizon states at a given energy level, which reproduces the Bekenstein's holographic bound for an imaginary Immirzi parameter. This allows us to recover the Bekenstein-Hawking entropy formula without the large quantum gravity corrections associated with the number of punctures.

description: In this paper, we consider a functional decode and forward (FDF) multi-way relay network (MWRN) where a common user facilitates each user in the network to obtain messages from all other users. We propose a novel user pairing scheme, which is based on the principle of selecting a common user with the best average channel gain. This allows the user with the best channel conditions to contribute to the overall system performance. Assuming lattice code based transmissions, we derive upper bounds on the average common rate and the average sum rate with the proposed pairing scheme. Considering M-ary quadrature amplitude modulation with square constellation as a special case of lattice code transmission, we derive asymptotic average symbol error rate (SER) of the MWRN. We show that in terms of the achievable rates, the proposed pairing scheme outperforms the existing pairing schemes under a wide range of channel scenarios. The proposed pairing scheme also has lower average SER compared to existing schemes. We show that overall, the MWRN performance with the proposed pairing scheme is more robust, compared to existing pairing schemes, especially under worst case channel conditions when majority of users have poor average channel gains.

Studies towards stratified approaches to smoking cessation with a focus on South Asians and effectiveness of varenicline

description: Smoking is a preventable risk factor for many diseases and cancers. Pharmacotherapies such as varenicline have been utilised to aid quit smoking attempts. However, the genetic underpinnings of response to varenicline are not well understood. Despite reported genetic associations with smoking behaviours in European populations, very few efforts have been made to investigate the genetic underpinnings of smoking behaviours in other populations such as South Asians, the second largest population in the UK. This thesis aims to investigate the genetic basis of the long term effectiveness of varenicline in the EXCEED Study, and the genetic basis of smoking initiation in South Asians in UK Biobank.In this thesis, I devised a phenotyping algorithm to study long term effectiveness of varenicline using linked primary care electronic health records. A candidate-gene case-control analysis of varenicline long term effectiveness was then performed which highlighted 7 SNPs across the nicotinic receptor subunit coding genes CHRNA7, CHRNA4, and CHRNB4 at nominal significance. The variant most significantly associated with successful cessation was in CHRNA4, the gene encoding the target receptor of varenicline. Finally, a genome-wide case-control analysis of smoking initiation (ever- vs never-smokers) in South Asians in the UK Biobank highlighted 11 SNPs in DIMT1-KIF2A-IPO11, RBM3, and BHLHE40 associated with smoking initiations with P < 5×10−6, signals not previously described in either South Asians or Europeans.These findings, if replicated, could provide insights into the biological mechanisms underlying successful cessation using varenicline, and underlying smoking initiation in South Asians.

description: Coupling an antisymmetric tensor field to the electromagnetic field in a dyonic Reissner-Nordström-AdS black hole background, we build a holographic model for the paramagnetism/ferromagnetism phase transition. In the case of zero magnetic field, the time reversal symmetry is broken spontaneously and spontaneous magnetization happens in low temperature. The critical exponents are in agreement with the ones from mean field theory. In the case of nonzero magnetic field, the model realizes the hysteresis loop of single magnetic domain and the magnetic susceptibility satisfies the Curie-Weiss law.

description: Work passion, whether harmonious or obsessive, has been the subject of reflection and study by numerous researchers. In this thesis, the concepts of work passion, job performance and satisfaction as well as the concepts of charismatic and empowering leadership will be analyzed. The research results were extracted from a convenience sample of 112 employees, in organizations. They showed the positive correlation between work passion and the variables from low degree of correlation to very high degree of correlation. It was concluded that the presence of autonomy in an organization enhances work passion and by extension the existence of empowering leadership as autonomy is an important component of work passion. It further shows the positive correlation between charismatic leadership and work passion

description: Finite temperature charmonium spectral functions in the pseudoscalar and vector channels are studied in lattice QCD with 2+1 flavours of dynamical Wilson quarks, on fine isotropic lattices (with a lattice spacing of 0.057 fm), with a non-physical pion mass of mπ≈ 545 MeV. The highest temperature studied is approximately 1.4Tc. Up to this temperature no significant variation of the spectral function is seen in the pseudoscalar channel. The vector channel shows some temperature dependence, which seems to be consistent with a temperature dependent low frequency peak related to heavy quark transport, plus a temperature independent term at \omega>0. These results are in accord with previous calculations using the quenched approximation.

description: We use analytic estimates and numerical simulations of test particles interacting with magnetohydrodynamic (MHD) turbulence to show that subsonic MHD turbulence produces efficient second-order Fermi acceleration of relativistic particles. This acceleration is not well-described by standard quasi-linear theory but is a consequence of resonance broadening of wave-particle interactions in MHD turbulence. We provide momentum diffusion coefficients that can be used for astrophysical and heliospheric applications and discuss the implications of our results for accretion flows onto black holes. In particular, we show that particle acceleration by subsonic turbulence in radiatively inefficient accretion flows can produce a non-thermal tail in the electron distribution function that is likely important for modeling and interpreting the emission from low luminosity systems such as Sgr A* and M87.

The Netherlands’ Pandemic Response Was Driven By Assumptions, Not Science

Publisher: name: Eurac Research

description: When the corona virus struck the Netherlands, its independent public health agency (RIVM) insisted, based on their own mathematical models, that “the Italian scenario” of steeply rising cases and death counts would not materialize. But the RIVM were largely modeling their own untested assumptions, while regularly exceeding their mandate and showing undue sensitivity to perceived political needs. A clear delineation of competencies – and pursuing those competencies vigorously – is one of the great pillars of the modern democratic state. It should be adhered to at all times – especially under pressure.
Transition-type change between an inverted Berezinskii-Kosterlitz-Thouless transition and an abrupt transition in the bond percolation on a random hierarchical small-world network

description: We study bond percolation on a one-parameter family of hierarchical small-world network, and find a meta-transition between the inverted BKT transition and the abrupt transition driven by changing the network topology. It is found that the order parameter is continuous and fractal exponent is discontinuous in the inverted BKT transition, and oppositely, the former is discontinuous and the latter is continuous in the abrupt transition. The gaps of the order parameter and fractal exponent in each transition go to vanish as approaching the meta-transition point. This point corresponds to a marginal power-law transition. In the renormalization group formalism, this meta-transition corresponds to the transition between transcritical and saddle-node bifurcations of the fixed point via a pitchfork bifurcation.

description: The electronic, magnetic and transport properties of Fe intercalated 2H-TaS2 have been investigated by means of the Korringa-Kohn-Rostoker (KKR) method. The non-stoichiometry and disorder in the system has been accounted for using the Coherent Potential Approximation (CPA) alloy theory. A pronounced influence of disorder on the spin magnetic moment has been found for the ferro-magnetically ordered material. The same applies for the spin-orbit induced orbital magnetic moment and magneto-crystalline anisotropy energy. The temperature-dependence of the resistivity of disordered 2H-Fe0.28TaS2 investigated on the basis of the Kubo-St\v{r}eda formalism in combination with the alloy analogy model has been found in very satisfying agreement with experimental data. This also holds for the temperature dependent anomalous Hall resistivity ρxy(T). The role of thermally induced lattice vibrations and spin fluctuations for the transport properties is discussed in detail.

description: The live migration of Virtual Machines (VMs) is a key technology in server virtualization solutions used to deploy Infrastructure-as-a-Service (IaaS) clouds. This process, on one hand, increases the elasticity, fault tolerance, and maintainability in the virtual environment. On the other hand, it increases the security challenges in cloud environments, especially when the migration is performed between different data centers. Secure live migration mechanisms are required to keep the security requirements of both cloud customers and providers satisfied. These mechanisms are known to increase the migration downtime of the VMs, which plays a significant role in the compliance to Service Level Agreements (SLAs). This paper discusses the main threats caused by live migration and the main approaches for securing the migration. The requirements of a comprehensive Quality of Service (QoS)-aware secure live migration solution that keeps both security and QoS requirements satisfied are defined.

description: Georgette Méliès may be considered to be one of the first film pioneers, since she started acting in her father’s films in 1896 and also became a projectionist and a camera operator, or opératrice de prise de vues, very early. Georgette Eugénie Jeanne Méliès was born on March 22, 1888 in Paris. Her father, Georges Méliès, had married Eugénie Génin three years before in June 1885 and Georgette was their first child. Thirteen years later, her brother, André, was born.

Azimuthal anisotropies of reconstructed jets in Pb+Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV in a multiphase transport model

description: Azimuthal anisotropies of reconstructed jets [$v_{n}^{jet} (n=2, 3)$] have been investigated in Pb+Pb collisions at the center of mass energy $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV within a framework of a multiphase transport (AMPT) model. The $v_{2}^{jet}$ is in good agreement with the recent ATLAS data. However, the $v_{3}^{jet}$ shows a smaller magnitude than $v_{2}^{jet}$, and approaches zero at a larger transverse momentum. It is attributed to the path-length dependence in which the jet energy loss fraction depends on the azimuthal angles with respect to different orders of event planes. The ratio $v_{n}^{jet}/\varepsilon_{n}$ increases from peripheral to noncentral collisions, and $v_{n}^{jet}$ increases with the initial spatial asymmetry ($\varepsilon_{n}$) for a given centrality bin. These behaviors indicate that the $v_{n}^{jet}$ is produced by the strong interactions between jet and the partonic medium with different initial geometry shapes. Therefore, azimuthal anisotropies of reconstructed jet are proposed as a good probe to study the initial spatial fluctuations, which are expected to provide constraints on the path-length dependence of jet quenching models.

Stability of Minkowski space in ghost-free massive gravity theory

description: The energy in the ghost-free massive gravity theory is calculated via explicitly resolving the initial value constraints for spherically symmetric deformations of flat space. It turns out that the energy is positive in some cases, but in other cases it can be negative and even unbounded from below. This could suggest that ghost instability is present. However, it seems that the negative energy states cannot communicate with the positive energy sector since the corresponding solutions of the constraint equations are either not globally defined, not asymptotically flat, or singular. As a result, they cannot describe initial data for the decay of flat space. At the same time, for globally regular and asymptotically flat solutions of the constraints the energy is always found to be positive. All of this suggests that there is a physical sector of the theory where the energy is positive and the ghost is suppressed, so that the theory is stable. The negative energies show up only in disjoint sectors and thus should be harmless.

description: We study the Laurent property, the irreducibility and co-primeness of discrete integrable and non-integrable equations. First we study a discrete integrable equation related to the Somos-4 sequence, and also a non-integrable equation as a comparison. We prove that the conditions of irreducibility and co-primeness hold only in the integrable case. Next, we generalize our previous results on the singularities of the discrete Korteweg-de Vries (dKdV) equation. In our previous paper (arXiv:1311.0060), we described the singularity confinement test (one of the integrability criteria) using the Laurent property, and the irreducibility, and co-primeness of the terms in the bilinear dKdV equation, in which we only considered simplified boundary conditions. This restriction was needed to obtain simple (monomial) relations between the bilinear form and the nonlinear form of the dKdV equation. In this paper, we prove the co-primeness of the terms in the nonlinear dKdV equation for general initial conditions and boundary conditions, by using the localization of Laurent rings and the interchange of the axes. We assert that co-primeness of the terms can be used as a new integrability criterion, which is a mathematical re-interpretation of the confinement of singularities in the case of discrete equations. v2, v3: minor revisions

description: If R-parity is only mildly violated then the lightest supersymmetric particle (LSP) can be stable over cosmologically time-scales and still account for the dark matter relic density. We examine the possibility of generating detectable X-ray lines from R-parity violating decays of keV-scale LSP dark matter to neutrino-photon pairs. Specifically, we consider scenarios in which the LSP is a light gravitino, bino, or hidden sector photino. Potential signals are discussed in the context of recent claims of an unidentified 3.5 keV X-ray line in studies of stacked galaxy clusters. We comment on the difficulties in obtaining the observed relic density for keV scale bino or hidden photino dark matter and some possible resolutions.

description: Magnesium gluconate is a classical organometallic salt used for the prevention and treatment of magnesium deficiency diseases. The objective of the current research was to explore the influence of The Trivedi Effect® - Energy of Consciousness Healing Treatment on the physicochemical, thermal and behavioral properties of magnesium gluconate using PXRD, PSD, FT-IR, UV-vis spectroscopy, TGA, and DSC analysis. Magnesium gluconate was divided into two parts – one part was control without any Biofield Energy Treatment, while another part was treated with the Biofield Energy Healing Treatment remotely by eighteen renowned Biofield Energy Healers and defined as the Biofield Energy Treated sample. The PXRD analysis exhibited significant alteration of the crystal morphology of the treated sample compared with the control sample. The crystallite size of the treated sample was remarkably changed from range -33.33% to 66.65% compared with the control sample. The average crystallite size was increased in the treated sample by 6.13% compared with the control sample. Particle size analysis revealed that the particle size at d10 value was significantly reduced in the treated sample by 13.20% compared with the control sample, although the particle size at d50 and d90 values were increased in the treated sample by 2.75% and 3.72%, respectively. The treated sample’s surface area was significantly enhanced (6.96%) compared with the control sample. The FT-IR and UV-vis analysis showed that the structure of magnesium gluconate remained similar in both the treated and control samples. The TGA analysis revealed that the weight loss of the first and second degradation steps in the treated sample was significantly decreased by 2.89% and 8.43%, respectively compared with the control sample, whereas at the third degradation step, the weight loss was enhanced by 14.80% compared with the control sample. The DSC analysis revealed that the melting point of the control and treated samples were 170.23°C and 170.25°C, respectively. The latent heat of fusion was significantly decreased by 6.15% in the treated sample compared with the control sample. The current study infers that The Trivedi Effect® - Energy of Consciousness Healing Treatment might lead to a new polymorphic form of magnesium gluconate, which could be more soluble and bioavailable compared with the untreated compound. Hence, the Biofield Energy Treated magnesium gluconate would be very useful to design better nutraceutical and/or pharmaceutical formulations that might offer better therapeutic responses against inflammatory diseases, immunological disorders, stress, aging and other chronic infections.
