description: We report a solution-processed, ligand supported synthesis of 15-20 nm thick Sb(2-x)Bi(x)Te3 nanoplatelets. After complete ligand removal by a facile NH3-based etching procedure, the platelets are spark plasma sintered to a p-type nanostructured bulk material with preserved crystal grain sizes. Due to this nanostructure, the total thermal conductivity is reduced by 60 % in combination with a reduction in electric conductivity of as low as 20 % as compared to the bulk material demonstrating the feasibility of the phonon-glass electron-crystal concept. An enhancement in the dimensionless thermoelectric figure of merit of up to 15 % over state-of-the-art bulk materials is achieved meanwhile shifting the maximum to significantly higher temperatures.

description: Forward models for the Mueller Matrix (MM) components of materials with relative magnetic permeability tensor μ \neq 1 are studied. 4x4 matrix formalism is employed to produce general solutions for the complex reflection coefficients and MMs of dielectric-magnetic materials having arbitrary crystal symmetry and arbitrary laboratory orientation. For certain orientations of materials with simultaneously diagonalizable ε and μ tensors (with coincident principal axes), analytic solutions to the Berreman equation are available. For the single layer thin film configuration of these materials, analytic formulas for the complex reflection and transmission coefficients are derived for orthorhombic or higher crystal symmetry. The separation of the magnetic and dielectric contributions to the optical properties of a material are demonstrated using measurements of the MM at varying angles of incidence.

description: A number of scenarios have been proposed for the origin of the supermassive black holes (SMBHs) that are found in the centres of most galaxies. Many such scenarios predict a high-redshift population of massive black holes (MBHs), with masses in the range 100 to 100000 times that of the Sun. When the Laser Interferometer Space Antenna (LISA) is finally operational, it is likely that it will detect on the order of 100 of these MBH binaries as they merge. The differences between proposed population models produce appreciable effects in the portion of the population which is detectable by LISA, so it is likely that the LISA observations will allow us to place constraints on them. However, gravitational wave detectors such as LISA will not be able to detect all such mergers nor assign precise black hole parameters to the merger, due to weak gravitational wave signal strengths. This paper explores LISA's ability to distinguish between several MBH population models. In this way, we go beyond predicting a LISA observed population and consider the extent to which LISA observations could inform astrophysical modellers. The errors in LISA parameter estimation are applied with a direct method which generates random sample parameters for each source in a population realisation. We consider how the distinguishability varies depending on the choice of source parameters (1 or 2 parameters chosen from masses, redshift or spins) used to characterise the model distributions, with confidence levels determined by 1 and 2-dimensional tests based on the Kolmogorov-Smirnov test.

description: Critical scholarship has elevated the problem of gender bias in data sets used to train virtual assistants (VAs). Most work has focused on explicit biases in language, especially against women, girls, femme-identifying people, and genderqueer folk; implicit associations through word embeddings; and limited models of gender and masculinities, especially toxic masculinities, conflation of sex and gender, and a sex/gender binary framing of the masculine as diametric to the feminine. Yet, we must also interrogate how masculinities are "coded" into language and the assumption of "male" as the linguistic default: implicit masculine biases. To this end, we examined two natural language processing (NLP) data sets. We found that when gendered language was present, so were gender biases and especially masculine biases. Moreover, these biases related in nuanced ways to the NLP context. We offer a new dictionary called AVA that covers ambiguous associations between gendered language and the language of VAs.

description: The origin of the highest energy cosmic rays remains an enigma. They offer a window to new physics, including tests of physical laws relevant to their propagation and interactions, at energies unattainable by terrestrial accelerators. They must be accelerated locally, as otherwise background radiations would severely suppress the flux of protons and nuclei, at energies above the Greisen-Zatsepin-Kuzmin (GZK) limit. Nearby Gamma Ray Bursts (GRBs), Hypernovae, Active Galactic Nuclei (AGNs) and their flares, have all been suggested and debated as possible sources. A local sub-population of type Ibc supernovae (SNe) with mildly relativistic outflows have been detected as sub-energetic GRBs or X-Ray Flashes (XRFs) and recently as radio afterglows without detected GRB counterparts. We measure the size-magnetic field evolution, baryon loading and energetics, using the observed radio spectra of SN 2009bb. We place such engine-driven SNe above the Hillas line and establish that they can readily explain the post-GZK UHECRs.

description: Dark patterns are deceptive and malicious properties of user interfaces that lead the end-user to do something different from intended or expected. While now a key topic in critical computing, most work has been conducted in Western contexts. Japan, with its booming app market, is a relatively uncharted context that offers culturally- and linguistically-sensitive differences in design standards, contexts of use, values, and language, all of which could influence the presence and expression of dark patterns. In this work, we analyzed 200 popular mobile apps in the Japanese market. We found that most apps had dark patterns, with an average of 3.9 per app. We also identified a new class of dark pattern: "Linguistic Dead-Ends" in the forms of "Untranslation" and "Alphabet Soup." We outline the implications for design and research practice, especially for future cross-cultural research on dark patterns.

description: Heavy ion collisions in the low energy run at Relativistic Heavy Ion Collider (RHIC) and future Facility for Antiproton and Ion Research (FAIR) in Germany are expected to produce a quark-gluon plasma that has a finite baryon chemical potential, allowing thus the possibility to study the location of the critical endpoint in the QCD phase diagram. In this talk, using a multiphase transport model, that includes interactions in both initial partonic and final hadronic matters and the transition between these two phases of matter, we discuss the effects of partonic interactions on observables such as the elliptic flow that have played essential roles in studying the properties of the net baryon free quark-gluon plasma produced in heavy ion collisions at higher energies at RHIC. Also, we study the effect of density fluctuations due to a first-order transition between the quark-gluon plasma and hadronic matter on fluctuations of hadron mean transverse momentum and produced deuteron number as well as on two-pion correlations. We further discuss the possibility of studying the mechanism of charm energy loss in the baryon-rich quark-gluon plasma and the properties of phi mesons in hot-dense matter produced in these collisions.

description: We construct the graviton propagator on de Sitter background in exact de Donder gauge. We prove that it must break de Sitter invariance, just like the propagator of the massless, minimally coupled scalar. Our explicit solutions for its two scalar structure functions preserve spatial homogeneity and isotropy so that the propagator can be used within the larger context of inflationary cosmology, however, it is simple to alter the residual symmetry. Because our gauge condition is de Sitter invariant (although no solution for the propagator can be) renormalization should be simpler using this propagator than one based on a noncovariant gauge. It remains to be seen how other computational steps compare.

description: Let $A\subseteq\{1,...,N\}$ and $P_1,...,P_\ell\in\Z[n]$ with $P_i(0)=0$ and $°P_i=k$ for every $1\leq i\leq\ell$. We show, using Fourier analytic techniques, that for every $\VE>0$, there necessarily exists $n\in\N$ such that \[\frac{|A\cap (A+P_i(n))|}{N}>(\frac{|A|}{N})^2-\VE\] holds simultaneously for $1\leq i\leq \ell$ (in other words all of the polynomial shifts of the set $A$ intersect $A$ "$\VE$-optimally"), as long as $N\geq N_1(\VE,P_1,...,P_\ell)$. The quantitative bounds obtained for $N_1$ are explicit but poor; we establish that $N_1$ may be taken to be a constant (depending only on $P_1,...,P_\ell$) times a tower of 2's of height $C_{k,\ell}^*+C\eps^{-2}$.

description: Within the soundscapes of open-plan offices, irrelevant speech has consistently been reported as the most distracting, and causing performance decrements for workers. Notwithstanding this generalization, the 'babble' created by multiple simultaneously active talkers can sometimes provide beneficial sound masking, but due to spatial release from masking (SRM), speech may still be sufficiently intelligible up to a certain number of talkers (estimated to be about four). This was explored within a highly-realistic office simulation, where the cognitive performance, and subjective distraction of participants were tested. The experimental design was a 4x2 factorial (4 talker numbers, 2 levels of broadband sound masking, as the factors). The results indicated that within lower sound pressure level (SPL) of broadband sound masking, multi-talker sound environments degraded cognitive tasks performance more than those with a single talker, suggesting SRM effects. For higher SPL broadband sound masking, the cognitive test scores were similar within the different talker numbers. The subjective distraction increased monotonically with the number of talkers, with higher distraction within lower SPL broadband sound masking. Overall, the results call into question the single talker assumption (being the most distracting) within the international standard for measuring open-plan office acoustic environments (ISO 3382-3:2012). Soundscapes with 4 simultaneous talkers were still not adequately providing beneficial 'babble' masking, and were more distracting than 1 active talker. In conclusion, it is suggested that the acoustics environment of open-plan offices needs better characterization by incorporating some of the complexity and psychoacoustics of multi-talker scenarios.
Bipolar Molecular Outflows and Hot Cores in GLIMPSE Extended Green Objects (EGOs)

description: We present high angular resolution Submillimeter Array (SMA) and Combined Array for Research in Millimeter-wave Astronomy (CARMA) observations of two GLIMPSE Extended Green Objects (EGOs)--massive young stellar object (MYSO) outflow candidates identified based on their extended 4.5 micron emission in Spitzer images. The mm observations reveal bipolar molecular outflows, traced by high-velocity 12CO(2-1) and HCO+(1-0) emission, coincident with the 4.5 micron lobes in both sources. SiO(2-1) emission confirms that the extended 4.5 micron emission traces active outflows. A single dominant outflow is identified in each EGO, with tentative evidence for multiple flows in one source (G11.92-0.61). The outflow driving sources are compact millimeter continuum cores, which exhibit hot-core spectral line emission and are associated with 6.7 GHz Class II methanol masers. G11.92-0.61 is associated with at least three compact cores: the outflow driving source, and two cores that are largely devoid of line emission. In contrast, G19.01-0.03 appears as a single MYSO. The difference in multiplicity, the comparative weakness of its hot core emission, and the dominance of its extended envelope of molecular gas all suggest that G19.01-0.03 may be in an earlier evolutionary stage than G11.92-0.61. Modeling of the G19.01-0.03 spectral energy distribution suggests that a central (proto)star (M ~10 Msun) has formed in the compact mm core (Mgas ~ 12-16 Msun), and that accretion is ongoing at a rate of ~10^-3 solar masses per year. Our observations confirm that these EGOs are young MYSOs driving massive bipolar molecular outflows, and demonstrate that considerable chemical and evolutionary diversity are present within the EGO sample.

description: We present in this paper a detailed analysis of the flexoelectric instability of a planar nematic layer in the presence of an alternating electric field (frequency $ω$), which leads to stripe patterns (flexodomains) in the plane of the layer. This equilibrium transition is governed by the free energy of the nematic which describes the elasticity with respects to the orientational degrees of freedom supplemented by an electric part. Surprisingly the limit $ω\to 0$ is highly singular. In distinct contrast to the dc-case, where the patterns are stationary and time-independent, they appear at finite, small $ω$ periodically in time as sudden bursts. Flexodomains are in competition with the intensively studied electro-hydrodynamic instability in nematics, which presents a non-equilibrium dissipative transition. It will be demonstrated that $ω$ is a very convenient control parameter to tune between flexodomains and convection patterns, which are clearly distinguished by the orientation of their stripes.

description: Uromys (Uromys) Peters, 1867 Type species. Mus macropus Gray, 1866 (= Hapalotis caudimaculatus Krefft, 1867). Revised diagnosis. The species of Uromys (Uromys) can be distinguished from the species of Uromys (Cyromys) by possessing the following features: i) incisive foramina very shortened, narrow, slit-like; ii) molars simple and elongated, M3 greatly reduced in size; iii) bony palate greatly lengthened posteriorly; v) interdental ridges multiplied, with more than seven, and as many as 12 present; vi) anterior cingulum of MJ greatly reduced, obliterated on only moderately worn teeth; vii) cranial characters listed under U. (Cyromys) primitive in their states in U. (Uromys). The following additional features are also useful in identifying species of the subgenus U. (Uromys). The lingual marginal ridges of the molar alveoli are enlarged. There are no frontotemporal ridges, but laterally directed processes of varying size are present behind the sutures. The medial and anterior walls of the orbitotemporal fossa are vertical, as is the preorbital foramen. The posterior ends of the nasals are not broadened, the zygomatic arches swing down to the level of the molar alveoli, the nasals slightly protrude anterior of the premaxillae, the incisors are orthodont, the paroccipital processes are short (not descending lower than the inferior margin of the external auditory meatus), the ascending rami of the dentary do not flare laterally, the toothrows are comparatively well spaced.

description: Trapped two-component Fermi gases allow for the investigation of the so-called BCS-BEC crossover by tuning the interspecies atom-atom $s$-wave scattering length scattering $a^{(aa)}$ from attractive to repulsive, including vanishing and infinitely large values. Here, we numerically determine the energy spectrum of the equal-mass spin-balanced four-fermion system---the smallest few-particle system that exhibits BCS-BEC crossover-like behavior---as a function of $a^{(aa)}$ using the stochastic variational approach. For comparative purposes, we also treat the two- and three-particle systems. States with vanishing and finite total angular momentum as well as with natural and unnatural parity are considered. In addition, the energy spectrum of weakly-attractive and weakly-repulsive gases is characterized by employing a perturbative framework that utilizes hyperspherical coordinates. The hyperspherical coordinate approach allows for the straightforward assignment of quantum numbers and furthermore provides great insights into the strongly-interacting unitary regime.

description: We calculate the thermophoretic drift of a charged single colloidal particle with hydrodynamically slipping surface immersed in an electrolyte solution in response to a small temperature gradient. Here, we rely on a linearized hydrodynamic approach for the fluid flow and the motion of the electrolyte ions while keeping the full nonlinearity of the Poisson-Boltzmann equation of the unperturbed system to account for possible large surface charging. The partial differential equations are transformed into a coupled set of ordinary differential equations in linear response. Numerical solutions are elaborated for parameter regimes of small and large Debye shielding and different hydrodynamic boundary conditions encoded in a varying slip length. Our results are in good agreement with predictions from recent theoretical work and successfully describe experimental observations on thermophoresis of DNA. We also compare our numerical results with experimental data on polystyrene beads.

Eschato-horror films
Creators: name: Hauka, David Phillip
Publisher: name: University of British Columbia
Year: 2014

description: This thesis studies American studio feature films whose narratives are inspired by the Bible’s Book of Revelation. I identify these films as belonging to a subgenre of supernatural horror I have named ‘eschato-horror’. American eschato-horror films reflect Christian eschatology and its violent visions of cosmic war between divine and satanic forces. While supernatural horror films exploit our fear of death and evil, American Eschato-horror ups the cultural stakes through its representations of pseudo Catholic and other Christian ritual, scripture, and iconography in its mission to frighten the viewer. Other national cinemas produce their own eschatology inspired films, but the American rendering of the genre as produced and exported by major Hollywood studios and distribution companies dominates screens world-wide. In order to better understand the cultural importance and usefulness of American Eschato-horror for film fans as well as self-identifying American Christian audiences, this thesis will study three examples of the genre, Constantine (Lawrence, 2005), Knowing (Proyas, 2009) and Legion (Stewart, 2010), all of which were produced by or for major American motion picture companies and distributors. Demonstrating that the version of eschatology found in their narratives reflects an identifiable American Protestant Christianity will be accomplished though an historical overview tracing Christianity from its roots as the marginalized, millennially-inspired “Jesus Cult,” to its evolution into one of the most powerful forces shaping American history and culture. The narrative elements associated with eschato-horror (monstrous women, self-sacrificing heroes, faithless priests, etc.), will be seen to be as much an expression of our collective fear of death and evil – forces James Carse associates with religion – as the Biblical illiteracy and confused understanding of Christianity identified by Stephen Prothero and Richard T. Hughes so central to contemporary America’s view of itself as being “a Christian Nation.” The reception of American Eschato-horror films as seen on film fan and Christian websites, especially in light of discourse similarities identified in film fan cults and religious cults, will be considered through the work of Matt Hills, Ernest Mathijs, Jamie Sexton and Jeff Hunter.

description: We present an analysis of a 37-ks observation of the supergiant fast X-ray transient (SFXT) IGR J17391-3021 (=XTE J1739-302) gathered with Suzaku. The source evolved from quiescence to a low-activity level culminating in three weak flares lasting ~3 ks each in which the peak luminosity is only a factor of 5 times that of the pre-flare luminosity. The minimum observed luminosity was 1.3x10^33 erg/s (d/2.7 kpc)^2 in the 0.5--10 keV range. The weak flares are accompanied by significant changes in the spectral parameters including a column density (nH = (4.1+-0.5)x10^22 /cm^2) that is ~2--9 times the absorption measured during quiescence. Accretion of obscuring clumps of stellar wind material can explain both the small flares and the increase in nH. Placing this observation in the context of the recent Swift monitoring campaign, we find that weak-flaring episodes, or at least epochs of enhanced activity just above the quiescent level but well below the moderately bright or high-luminosity outbursts, represent more than 60+-5% of all observations in the 0.5--10keV energy range making this the most common state in the emission behavior of IGR J17391-3021

description: With the advance of Web Services technologies and the emergence of Web Services into the information space, tremendous opportunities for empowering users and organizations appear in various application domains including electronic commerce, travel, intelligence information gathering and analysis, health care, digital government, etc. However, the technology to organize, search, integrate these Web Services has not kept pace with the rapid growth of the available information space. The number of Web Services to be integrated may be large and continuously changing. To ease and improve the process of Web services discovery in an open environment like the Internet, it is suggested to gather similar Web services into groups known as communities. Although Web services are intensively investigated, the community management issues have not been addressed yet In this paper we draw an overview of several Web services Communities' management approaches based on some currently existing communities platforms and frameworks. We also discuss different approaches for querying and selecting Web services under the umbrella of Web services communities'. We compare the current approaches among each others with respect to some key requirements.

description: We present a study of the line-of-sight magnetic fields in five large-diameter Galactic HII regions. Using the Faraday rotation of background polarized radio sources, as well as dust-corrected H-alpha surface brightness as a probe of electron density, we estimated the strength and orientation of the magnetic field along 93 individual sight-lines through the HII regions. Each of the HII regions displayed a coherent magnetic field. The magnetic field strength (line-of-sight component) in the regions ranges from 2 to 6 microgauss, which is similar to the typical magnetic field strength in the diffuse interstellar medium. We investigated the relationship between magnetic field strength and electron density in the 5 HII regions. The slope of magnetic field vs. density in the low-density regime (0.8 < n_e < 30 per cubic cm) is very slightly above zero. We also calculated the ratio of thermal to magnetic pressure, beta_th, for each data point, which fell in the range 1.01 < beta_th < 25. Finally, we studied the orientation of the magnetic field in the solar neighborhood (d < 1.1 kpc) using our data from 5 HII regions along with existing measurements of the line-of-sight magnetic field strength from polarized pulsars whose distances have been determined from their annual parallax. We identify a net direction for the magnetic field in the solar neighborhood, but find no evidence for a preferred vertical direction of the magnetic field above or below the Galactic plane.

description: We consider the nonlinear integer programming problem of minimizing a quadratic function over the integer points in variable dimension satisfying a system of linear inequalities. We show that when the Graver basis of the matrix defining the system is given, and the quadratic function lies in a suitable {\em dual Graver cone}, the problem can be solved in polynomial time. We discuss the relation between this cone and the cone of positive semidefinite matrices, and show that none contains the other. So we can minimize in polynomial time some non-convex and some (including all separable) convex quadrics. We conclude by extending our results to efficient integer minimization of multivariate polynomial functions of arbitrary degree lying in suitable cones.

description: Our study focuses on analyzing the behavior of a stochastic predator-prey model with a time delay and logistic growth of prey, influenced by Lévy noise. Initially, we establish the existence, uniqueness, and boundedness of a positive solution that spans globally. Subsequently, we explore the conditions under which extinction occurs, and identify adequate criteria for persistence. Finally, we validate our theoretical findings through numerical simulations, which also helps illustrate the dynamics of the stochastic delayed predator-prey model based on different criteria.

description: Two proof-of-principle experiments towards T1-limited magnetic resonance imaging with NV centers in diamond are demonstrated. First, a large number of Rabi oscillations is measured and it is demonstrated that the hyperfine interaction due to the NV's 14N can be extracted from the beating oscillations. Second, the Rabi beats under V-type microwave excitation of the three hyperfine manifolds is studied experimentally and described theoretically.

description: The need to find low power alternatives to digital electronic circuits has led to increasing interest in alternative switching schemes like the magnetic quantum cellular automata(MQCA) that store information in nanomagnets which communicate through their magnetic fields. A recent proposal called all spin logic (ASL) proposes to communicate between nanomagnets using spin currents which are spatially localized and can be conveniently routed. The objective of this paper is to present a model for ASL devices that is based on established physics and is benchmarked against available experimental data and to use it to investigate switching energy-delay of ASL devices.

Impact of Single Links in Competitive Percolation -- How complex networks grow under competition

description: How a complex network is connected crucially impacts its dynamics and function. Percolation, the transition to extensive connectedness upon gradual addition of links, was long believed to be continuous but recent numerical evidence on "explosive percolation" suggests that it might as well be discontinuous if links compete for addition. Here we analyze the microscopic mechanisms underlying discontinuous percolation processes and reveal a strong impact of single link additions. We show that in generic competitive percolation processes, including those displaying explosive percolation, single links do not induce a discontinuous gap in the largest cluster size in the thermodynamic limit. Nevertheless, our results highlight that for large finite systems single links may still induce observable gaps because gap sizes scale weakly algebraically with system size. Several essentially macroscopic clusters coexist immediately before the transition, thus announcing discontinuous percolation. These results explain how single links may drastically change macroscopic connectivity in networks where links add competitively.

description: Uromys caudimaculatus caudimaculatus (Krefft, 1867) Synonyms. Mus macropus (Gray, 1866) (not of Waterhouse); Uromys aruensis Gray, 1873; Uromys validus Peters & Doria, 1881; Uromys exilis Troughton & Le Soeuf, 1929 ; Uromys sherrini Thomas, 1923. Revised diagnosis. Distinguished from other subspecies as follows: i) hindfoot short, 18-22% of head and body length; ii) size large (condylobasal length of adults 63-72 mm); iii) fur colour "rabbity" grey brown or tawny, with underparts yellow or white; iv) feet white with a distinct brown line or block above; v) tail long, with only slight mottling in transition zone; vi) scales arranged in clear rings; frontal region of skull convex; vii) bullae somewhat flattened. Discussion. There is more regional variation within U. c. caudimaculatus than in any other subspecies. Indeed, some of the more distinct regional forms have previously been recognised as subspecies. Individuals from the Aru Islands are smaller than those from elsewhere, and differ morphologically in possessing a distinct dorsal stripe. Those from the trans-Fly plains are again a little smaller than individuals from Australia, possess an indistinct dorsal stripe, have slightly less of the tail white, and have less warm tones in the fur. The Australian sample is, in contrast, remarkably morphologically homogeneous throughout its range. Baverstock et al. (1982), however, recognised two chromosome races within it: the southern race is characterised by the possession of two to 12 B chromosomes while the northern race lacks B chromosomes but possesses large blocks of distal C-positive heterochromatin on between 18 and 28 of the 46 chromosomes. Although these two chromosome races seem to be isolated from one another, and no chromosome intermediates are known, we could detect no differences based upon morphology or morphometrics to support the division of the Australian sample into two taxa. Distribution. This subspecies is distributed from north-east Queensland throughout the trans-Fly plains to the Gulf of Papua and the Aru Islands.

description: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion-exclusion criteria, safety, and pharmacodynamic indexes were reviewed.
New anticoagulants under development focused on inhibiting one or more than one serine proteases within the coagulation cascade. Agents targeting intrinsic factors are in the pipeline of the drug development. The enrollment eligibility criteria have more restrictions on laboratory tests, medical history, or medication history related to bleeding and coagulation; more precautions were taken to assess and minimize the risk of hemorrhagic events. Pharmacodynamics markers were evaluated as a surrogate marker of anticoagulation potency to guide further dose selection in drug’s development. In future, the positive control study can be applied in phase I studies of new anticoagulants with appropriate pharmacodynamics markers, which can provide more favorable information on making ‘go/no’ decision in drug development.

description: This paper proposes a blockchain-based Federated Learning (FL) framework with Intel Software Guard Extension (SGX)-based Trusted Execution Environment (TEE) to securely aggregate local models in Industrial Internet-of-Things (IIoTs). In FL, local models can be tampered with by attackers. Hence, a global model generated from the tampered local models can be erroneous. Therefore, the proposed framework leverages a blockchain network for secure model aggregation. Each blockchain node hosts an SGX-enabled processor that securely performs the FL-based aggregation tasks to generate a global model. Blockchain nodes can verify the authenticity of the aggregated model, run a blockchain consensus mechanism to ensure the integrity of the model, and add it to the distributed ledger for tamper-proof storage. Each cluster can obtain the aggregated model from the blockchain and verify its integrity before using it. We conducted several experiments with different CNN models and datasets to evaluate the performance of the proposed framework.
Automated choice of the best renormalization scheme

description: High-precision predictions in BSM models require calculations at the loop-level and thus a renormalization of (some of) the BSM parameter. Here many choices for the renormalization scheme (RS) are possible. A given RS can be well suited to yield ``stable'' and ``well behaved'' higher-order corrections in one part of the BSM parameter space, but can fail completely in other parts. The latter may not even be noticed numerically if an isolated parameter point is investigated. Here we review a new method for choosing a ``well behaved'' RS. We demonstrate the feasibility of our new method in the chargino/neutralino sector of the Minimal Supersymmetric Standard Model (MSSM), but stress the general applicability of our method to all types of BSM models.

description: Uromys anak Thomas, 1907 Type material. HOLOTYPE, BM 7.5.22.2, adult male skin and skull, from Efogi (9°00'S 147°45'E), Owen Stanley Range at not less than 4,000 ft (1200 m). Collected 2 Oct. 1906 by C.A.W. Monckton. Revised diagnosis. Uromys anak differs from all species of U. (Uromys) except U. neobritannicus and U. boeadii n.sp. in lacking a white tail tip. It differs from U. neobritannicus in its less well-developed postorbital processes, and in having the interorbital region more concave, and in its brown and white mixed underparts. It differs from members of the U. caudimaculatus group in that its tail scales are broader than long, its palatal foramina are short (only 14-19% of palate length), the molars are large (more than 20.5% of condylobasal length); in its less bowed zygomatic arches, larger postorbital processes continued downward as swollen ridges, posteriorly extended nasals, flatter braincase, more flattened auditory bullae, less anteriorly protruding nasals and deeper rostrum. Notes. The Discriminant Analysis (Fig. 5) shows an almost clean division between samples from Mount Simpson and the Mount Hagen region, and these are here recognised as distinct subspecies. Two specimens from Telefomin and one from Mount Elimbari also stand well apart from the rest. Unfortunately no specimen from the Huon Peninsula is complete enough to enter into the analysis. As a high-altitude species, it is possible that a number of distinctive and semi-isolated subspecies will eventually be discernible.
