description: Adopting a non geometrical point of view, we are led to an alternative theory of the order two and symetric gravitational tensor field of GR. The field is no more interpreted as the metric of our space-time. The true metric is globally Minkowskian and describes a flat manifold, a context which justifies a genuine rehabilitation of the global discrete space-time symetries involved in the structure of the Lorentz group along with their 'problematic' representations: the negative energy and tachyonic ones.

description: Using the mosaic of nine XMM-Newton observations, we study the hydrodynamic state of the merging cluster of galaxies Abell 3266. The high quality of the spectroscopic data and large field of view of XMM-Netwon allow us to determine the thermodynamic conditions of the intracluster medium on scales of order of 50 kpc. A high quality entropy map reveals the presence of an extended region of low entropy gas, running from the primary cluster core toward the northeast along the nominal merger axis. The mass of the low entropy gas amounts to approximately 2e13 solar masses, which is comparable to the baryonic mass of the core of a rich cluster. We test the possibility that the origin of the observed low entropy gas is either related to the disruption a preexisting cooling core in Abell 3266 or to the stripping of gas from an infalling subcluster companion. We find that both the radial pressure and entropy profiles as well as the iron abundance of Abell 3266 do not resemble those in other known cooling core clusters (Abell 478). Thus we conclude that the low entropy region is subcluster gas in the process of being stripped off from its dark matter halo. In this scenario the subcluster would be falling onto the core of A3266 from the foreground. This would also help interpret the observed high velocity dispersion of the galaxies in the cluster center, provided that the mass of the subcluster is at most a tenth of the mass of the main cluster.

Bounds on Plack-scale deformation of CPT from lifetimes and interference

description: Deformed relativistic kinematics, expected to emerge in a flat-spacetime limit of quantum gravity, predicts violation of discrete symmetries at energy scale in the vicinity of the Planck mass. Momentum-dependent deformations of the C, P and T invariance are derived from the \k{appa}-deformed Poincaré algebra. Deformation of the CPT symmetry leads to a subtle violation of Lorentz symmetry. This entails some small but measurable phenomenological consequences, as corrections to characteristics of time evolution: particle lifetimes or frequency of flavour oscillations in two-particle states at high energy. We argue here that using current experimental precisions on the muon lifetime one can bound the deformation parameter \k{appa} > 10^14 GeV at LHC energy and move this limit even to 10^16 GeV at Future Circular Collider, planned at CERN. Weaker limits on deformation can be also obtained from interference of neutral mesons. In case of B0s from Υ decay it amounts to \k{appa} > 10^8 GeV at confidence level 99%.

Mould heat transfer in the high speed continuous casting of steel slabs
Creators: name: Singh, Himanshu
Publisher: name: University of British Columbia
Year: 2009

description: This investigation studies mould heat removal in operational slab casters. These include both the conventional (or thick slab) as well as thin slab (of the CSP type) casters. Mould wall temperatures and other data measured in-plant were analysed using mathematical models developed by other researchers, in addition to new models and commercial finite element software. The primary objective was the calculation of mould heat fluxes, and how this related to aspects of caster operation and slab surface quality. Firstly, the mechanism of heat transfer in slab caster moulds postulated by previous researchers was validated. Heat fluxes calculated for a billet caster using powder lubrication showed that reducing cooling water velocities resulted in an increase in heat transfer. This is due to higher mould hot face temperatures causing the formation of a smaller slag rim, and a hotter, more fluid liquid flux. This mechanism of mould heat transfer was used to resolve transverse corner cracking in a newly commissioned conventional slab caster which had commenced high speed casting. The problem was traced to inadequate mould lubrication and heat transfer, caused by inordinately high water velocities. The incidences of cracking fell drastically after a reduction in cooling water velocities. Secondly, heat fluxes were calculated for the CSP caster. A big dip in heat fluxes was seen in the central portion of the fixed broad face. It was postulated that this could be due to a combination of water flow differential between the two broad faces, and a squeezing in of the mould pocket bulge in the strand. Additionally, the two broad faces, as well the narrow faces, were found to have unequal heat extraction rates. Finally, the effect of the mould hot face temperature on the mould heat transfer was used to develop a procedure of water velocity variation into the working life of CSP caster moulds. Models were used to calculate water velocities which maintained a constant hot face temperature, while the wall thickness reduced. It was found that the current operational practice grossly over-estimated the water flows required in the latter stages of the mould life.

description: Few-shot learning for fine-grained image classification has gained recent attention in computer vision. Among the approaches for few-shot learning, due to the simplicity and effectiveness, metric-based methods are favorably state-of-the-art on many tasks. Most of the metric-based methods assume a single similarity measure and thus obtain a single feature space. However, if samples can simultaneously be well classified via two distinct similarity measures, the samples within a class can distribute more compactly in a smaller feature space, producing more discriminative feature maps. Motivated by this, we propose a so-called \textit{Bi-Similarity Network} (\textit{BSNet}) that consists of a single embedding module and a bi-similarity module of two similarity measures. After the support images and the query images pass through the convolution-based embedding module, the bi-similarity module learns feature maps according to two similarity measures of diverse characteristics. In this way, the model is enabled to learn more discriminative and less similarity-biased features from few shots of fine-grained images, such that the model generalization ability can be significantly improved. Through extensive experiments by slightly modifying established metric/similarity based networks, we show that the proposed approach produces a substantial improvement on several fine-grained image benchmark datasets.

description: We establish the existence of infinitely many \emph{polynomial} progressions in the primes; more precisely, given any integer-valued polynomials $P_1, >..., P_k \in \Z[\m]$ in one unknown $\m$ with $P_1(0) = ... = P_k(0) = 0$ and any $\eps > 0$, we show that there are infinitely many integers $x,m$ with $1 \leq m \leq x^\eps$ such that $x+P_1(m), ..., x+P_k(m)$ are simultaneously prime. The arguments are based on those in Green and Tao, which treated the linear case $P_i = (i-1)\m$ and $\eps=1$; the main new features are a localization of the shift parameters (and the attendant Gowers norm objects) to both coarse and fine scales, the use of PET induction to linearize the polynomial averaging, and some elementary estimates for the number of points over finite fields in certain algebraic varieties.

description: We propose a scheme for universal quantum computing based on Kramers rare-earth ions. Their nuclear spins in the presence of a Zeeman-split electronic crystal field ground state act as 'passive' qubits which store quantum information. The qubits can be activated optically by fast coherent transitions to excited crystal field states with a magnetic moment. The dipole interaction between these states is used to implement CNOT gates. We compare our proposal with a similar one based on phosphorus donor atoms in silicon and discuss the significantly improved CNOT gate time as compared to rare-earth implementations via the slower dipole blockade.

description: Spectroscopy of the infrared He I (10830A) line with KECK/NIRSPEC and IRTF/CSHELL, and of the ultraviolet C III (977A) and O VI (1032A) emission with FUSE reveals that the classical T Tauri star TW Hydrae exhibits P Cygni profiles, line asymmetries, and absorption indicative of a continuous, fast (~400 km/s), hot (~300,000 K) accelerating outflow with a mass loss rate \~10^-11 - 10^-12 solar masses per year, or larger. Spectra of T Tauri N appear consistent with such a wind. The source of the emission and outflow seems restricted to the stars themselves. Although the mass accretion rate is an order of magnitude less for TW Hya than for T Tau, the outflow reaches higher velocities at chromospheric temperatures in TW Hya. Winds from young stellar objects may be substantially hotter and faster than previously thought.

description: Stone cutting with diamond wires results in the progressive and concurrent wear of the natural
stone and the cutting tool (diamond wires - diamond beads). This phenomenon has been
investigated since the beginning of stone machining, but there are still several open questions
concerning the parameters controlling it. The aim of this study is to establish correlations between
the natural stone mineralogical composition and the diamond wires cut performance in terms of
efficiency, productivity and diamond beads consumption. This investigation requires a
multidisciplinary approach. Microscopic analysis have been done in order to investigate the wear
processes of the diamond beads in terms of super-abrasive grains (diamond grits) damage and
pull out. Petrographic analysis and mineralogical investigation have been considered in order to
correlate the removal rate during the cutting action with the characteristics of the stones. Muds
derived from cutting have been characterized for the complete comprehension of the cutting
process. The erosion analysis concerned both stone debris and diamond beads, characterizing
both the metal powder and super-abrasive grains (diamond) in the cut waste (mud). Moreover, the
metal matrix is the core of the diamond wire technology and it drives cutting performance and
efficiency.

description: There is no list of bipolar active regions (ARs) with reverse polarity (anti-Hale regions), although statistical investigations of such ARs (bearing the imprint of deep subphotospheric processes) are important for understanding solar-cycle mechanisms. We studied 8606 ARs from 1 January 1989 to 31 December 2018 to detect anti-Hale regions and to compile a catalog. The Solar and Heliospheric Observatory (SOHO) and the Solar Dynamics Observatory (SDO) data, as well as the Debrecen Photoheliographic Data, the Mount Wilson Observatory catalog and drawings, and the USAF/NOAA Solar Region Summary were used. Complex, ambiguous cases related to anti-Hale region identification were analyzed. Two basic and four additional criteria to identify an AR as an anti-Hale region were formulated. The basic criteria assume that: i) dominating features of an AR have to form a bipole of reverse polarity with sunspots/pores of both polarities being present; ii) magnetic connections between the opposite polarities has to be observed. A catalog of anti-Hale regions (275 ARs) is compiled. The catalog contains: NOAA number, date of the greatest total area of sunspots, coordinates, and corrected sunspot area for this date. The tilt and the most complex achieved Mount Wilson magnetic class are also provided. The percentage of anti-Hale groups meeting the proposed criteria is ~3.0% from all studied ARs, which is close to early estimations by authors who had examined each AR individually: ~2.4% by Hale and Nicholson (Ap.J. 62, 270, 1925) and ~3.1% by Richardson (Ap.J. 107, 78, 1948). The enchancement of the anti-Hale percentage in later research might be related to: i) increasing sensitivity of instruments (considering smaller and smaller bipoles); ii) the ambiguities in the anti-Hale region identification.

description: While there has been a flurry of research in algorithmic fairness, what is less recognized is that modern antidiscrimination law may prohibit the adoption of such techniques. We make three contributions. First, we discuss how such approaches will likely be deemed "algorithmic affirmative action," posing serious legal risks of violating equal protection, particularly under the higher education jurisprudence. Such cases have increasingly turned toward anticlassification, demanding "individualized consideration" and barring formal, quantitative weights for race regardless of purpose. This case law is hence fundamentally incompatible with fairness in machine learning. Second, we argue that the government-contracting cases offer an alternative grounding for algorithmic fairness, as these cases permit explicit and quantitative race-based remedies based on historical discrimination by the actor. Third, while limited, this doctrinal approach also guides the future of algorithmic fairness, mandating that adjustments be calibrated to the entity's responsibility for historical discrimination causing present-day disparities. The contractor cases provide a legally viable path for algorithmic fairness under current constitutional doctrine but call for more research at the intersection of algorithmic fairness and causal inference to ensure that bias mitigation is tailored to specific causes and mechanisms of bias.

We have determined the structure and energetics of YCrO3 with ferromagnetic and antiferromagnetic ordering by means of first-principles density functional theory calculations, based on pseudopotentials and a plane wave basis. The non-centrosymmetric monoclinic structure is found to be lower in energy than the orthorhombic structure, supporting the biferroic nature of YCrO3.

Diamond wire cutting technology and workability of natural stones: validation of a new classification method (EASE R3)

description: In the diamond wire stone cutting process the objective is to remove a chip of material or a layer of
uniform thickness from the entire length of the cut. The aim of this study is to correlate the cutting
performance to the characteristics of the natural stone and subsequently to propose a method of
classification strictly connected to stone workability.
Hardness and micro-hardness tests are currently considered important methods for acquiring
useful information about the workability of natural stones, but such gathered data alone do not give
enough information to establish a satisfying classification. The concept of workability and stone
machining has been, for the past thirty years, one of the main area of investigation in national and
international researches. This study endorses a method for the prediction of stone-cutting tools
interaction (mainly diamond wires) combining the micro-hardness and the UPV measurements,
that better represent the mechanical, physical and petrographical stone properties.
This paper studies eight different stones classified according to an “easy-to-cut” scale based on the
historical company know-how (HIC - Historical Industrial Classification). This classification is
based upon experience and not on explicit or really scientifically quantified parameters,
nonetheless, it describes the stones workability completely.
In previous works, however, criteria based on quantifiable parameters (SSC - Scientific Stone
Classification) have been pursued and this led to a scientific correlation with the industrial
classification. For each stone the following investigation techniques were performed: petrographic
analysis, micro-hardness, Schmidt rebound, Ultrasound Pulse Velocity (UPV). Moreover UPV
measures in indirect and direct method have been executed on stone blocks in the cutting plant
and compared with those performed on slabs. The results of all the performed tests were analyzed
and good correlations with the industrial classification were found.

Design of an active fluid damping system for vibration control of disk-shaped tools

description: To meet the requirements of today´s cutting process of natural stones thin disk-shaped tools with
large diameter are applied at high cutting velocities. To use these tools, guiding systems for the disks
are needed. Therewith, tool vibration magnitudes and deflections can be reduced. The risk of producing
scrap parts or tool damage are decreased. However, the guidance being placed close to the
cutting zone reduces the cutting depth, so that the process is limited to the production of small slabs
and tiles. To use the advantage of a guidance without limiting depth of cut, a new guidance concept
is presented. Thereby the guiding areas are placed opposite to the cutting zone. This enables the
reduction of tool vibration without decreasing the depth of cut. In this paper the compensation of tool
vibration by this guiding concept is investigated. Different types of guidance are compared and the
most suitable compensation approach is identified. Further on, the problem of the decreasing compensation
effect, due to the increasing distance between the excitation and the guidance is considered.
To increase the compensation effect, the guidance is optimized regarding to the number and
positon of guiding areas. The capability of the presented concept is verified by a comparison with a
conventionally placed guiding system.

description: Due to their abrasive qualities, machining of hard and brittle materials is predominantly performed
using tools with geometrically indefinite cutting edge. However, these processing
methods offer only low productivity, which often can be increased by superimposing ultrasonic
vibrations to the process. At the same time this hybrid process design involves great uncertainties,
as influencing factors and the mechanism of action are not sufficiently described
yet. In order to close this knowledge gap, firstly the occurrences on the scale of single abrasive
grains shall be observed. This should increase the overall process understanding and
reveal fundamental interrelations of machining with geometrically indefinite cutting edge. To
achieve this, scratch tests with well-defined boundary conditions will be performed, analyzed
and compared. As a result of the experiments the interdependencies of process forces, cutting
speed, ultrasonic amplitude and depth of cut will be presented.

description: We theoretically study spin pumping from a layered van der Waals antiferromagnet in its canted ground state into an adjacent normal metal. We find that the resulting dc spin pumping current bears contributions along all spin directions. Our analysis allows for detecting intra- and cross-sublattice spin-mixing conductances via measuring the two in-plane spin current components. We further show that sublattice symmetry-breaking Gilbert damping can be realized via interface engineering and induces a dissipative coupling between the optical and acoustic magnon modes. This realizes magnon level attraction and exceptional points in the system. Furthermore, the dissipative coupling and cross-sublattice spin pumping contrive to produce an unconventional spin current in the out-of-plane direction. Our findings provide a route to extract the spin mixing conductance matrix and uncovers the unique opportunities, such as level attraction, offered by van der Waals antiferromagnet-normal metal hybrids.

tool dimensions have an influence on these pattern. In this paper a new method is presented
for the design of cut-off grinding segments for circular saws with defined grain pattern, which
is based on the in-house material removal simulation software CutS. With this simulation, the
influence of variable grain pattern on tool performance and tool life can be tested without the
need for cutting experiments. It is possible to test different material specifications through the
consideration of brittle and ductile material removal mechanisms and adjustable material
removal factors. The influence of macroscopic and microscopic tool wear on the optimized
positioning of grains by means of material removal rate and wear rate is investigated. With
special algorithms, it is also possible to simulate standard tools with stochastically distributed
diamond grains. Computed results will be compared to real cutting experiments of granite
with cut-off grinding segments designed with CutS.

description: With the medical development in recent decades, the multiplicity of different diseases, and an increased number of patients, the use of an advanced healthcare information technology (HIT) such as a clinical decision support system (CDSS) has been of necessary to help general practitioners (GPs). CDSS may fail due to the failure to understand the factors influencing the GP's acceptance of CDSS. Identifying factors that promote acceptance of CDSS can be a vital aspect for its successful implementation. This study seeks to identify factors that influence the acceptance of CDSS in Saudi Arabia by GPs. This study relies mainly on the unified theory of acceptance and use of technology (UTAUT) which has been integrated with a task-technology fit (TTF) model and has applied a qualitative method to collect the data through using semi-structured interviews with 12 GPs. The study's results indicated that performance expectancy, effort expectancy, facilitating conditions, technology fit for the task, technology characteristics and task characteristics have all influenced the acceptance of CDSS. The results also indicated the need to extend the UTAUT model to investigate and explore other factors in GPs' acceptance of CDSS.

Evaluation of the operational costs for chain saw cutting
Creators: name: Dagrain, Fabrice
Publisher: name: International Conference on Stone and Concrete Machining (ICSCM)
Year: 2015
Subjects: Chain saw; tools; optimization; efficiency; operational cost; profitability

description: Chain saw cutting technology has been widely described by the author those last years in several
scientific and technical articles. The main problems encountered on chain saw machines have
been described. Several experimental approaches have been developed in laboratory to better
understand the stone cutting mechanisms and to improve the efficiency of the machines. New
cutting designs have been developed increasing the performances of the machines. Monitoring
systems have been introduced on the machines to follow their performances while operating in
quarries. Even if the technology is well described, very few information can be found on the costs
of the technique.
This paper overcomes this lack of information and introduces a rigorous methodology to estimate
the real costs of the sawing operations with chain saw machines. The technological parameters
introduced and described in the literature have been implemented in a cost evaluation program
developed by Stone Assistance, in order to evaluate their influence on the chain saw operational
costs. The objective of the paper is to present some interesting results that should be considered
by the engineers or operators working with chain saw machines, and that could help them to
manage the operations with chain saw machines in quarries.

Toroidal LNRF-velocity profiles in thick accretion discs orbiting rapidly rotating Kerr black holes

description: We show that in the equatorial plane of marginally stable thick discs (with uniformly distributed specific angular momentum the orbital velocity relative to the locally non-rotating frames (LNRF) has a positive radial gradient in the vicinity of black holes with spin a>0.99979. The change of sign of the velocity gradient occurs just above the center of the thick toroidal discs, in the region where stable circular geodesics of the Kerr spacetime are allowed. The global character of the phenomenon is given in terms of topology changes of the von Zeipel surfaces (equivalent to the equivelocity surfaces in the tori with constant specific angular momentum distribution). Toroidal von Zeipel surfaces exist around the circle corresponding to the minimum of the equatorial LNRF velocity profile, indicating a possibility of development of some vertical instabilities in those parts of marginally stable tori with positive gradient of the LNRF velocity. Eventual oscillatory frequencies connected with the phenomenon are given in a coordinate-independent form.

description: In this work, we study an LQG control system where one of two feedback channels is discrete and incurs a communication cost. We assume that a decoder (co-located with the controller) can make noiseless measurements of a subset of the state vector (referred to as side information) meanwhile a remote encoder (co-located with a sensor) can make arbitrary measurements of the entire state vector, but must convey its measurements to the decoder over a noiseless binary channel. Use of the channel incurs a communication cost, quantified as the time-averaged expected length of prefix-free binary codeword. We study the tradeoff between the communication cost and control performance. The formulation motivates a constrained directed information minimization problem, which can be solved via convex optimization. Using the optimization, we propose a quantizer design and a subsequent achievability result.

Evidence for dust reddening in DLAs identified through CaII H&K absorption
Creators: name: Wild, Vivienne

Publisher: name: arXiv

description: We present a new sample of 31 CaII(H&K) 3935,3970 absorption line systems with 0.8499.99% confidence. The discovery of significant amounts of dust in a subsample of DLAs has direct implications for studies of the metallicity evolution of the universe and the nature of DLAs in relation to high redshift galaxies. The gas:dust ratio is discussed. Our results suggest that at least ~40% of the CaII absorption systems are excluded from the magnitude-limited SDSS quasar sample as a result of the associated extinction, a fraction similar to the upper limit deduced at higher redshifts from radio-selected surveys.

description: In this work, the influence of surface roughness of a natural stone material on two important
parameters for the performance of the industrial coating process will be studied. The selected
parameters are contact liquid drop angle, to assess the best conditions for the application of the
liquid coatings, and the adhesion strength, to assess the best coating performance once the
coating has been applied and dried. These two parameters are quantitative and may allow the
comparison between different case studies. The study of influence will be addressed in this work
from a practical point of view, so that results can be applied in a current industrial process for
optimization purposes. The obtained conclusions are expected to be used to propose
recommendations for the stone industry to guarantee the performances of the coating systems
applied.

description: We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT mission, which have been obtained from ground-based observations since the mission's end in 2012, with the objective to maintain the ephemeris of these planets. Twelve of the observed planets are in the CoRoT fields near the galactic center and the remaining eight planets are in the fields near the anticenter. We detect indications for significant transit timing variations in the cases of CoRoT 3b, 11b, 13b, 27b. For two more planets (CoRoT 18b and 20b) we conclude that timing offsets in early follow-up observations led to ephemeris in discovery publications that are inconsistent with timings from follow-up observations in later epochs. In the case of CoRoT-20b, this might be due to the influence from a further non-transiting planet. We also note that a significant majority (23 of 33) of our reported minimum times have negative O-C values, albeit most of them are within the expected uncertainty of the ephemeris.

Executive summary

In this study, we present a first evaluation of global storm resolving models and their ability to capture diurnal variability over land. We particularly focus on how the combination of resolving storms and resolving landscapes (detailed land-use and orography) at kilometer-scale resolutions impacts the energy and water balance. Two prototypes storm-resolving models (ICON and IFS) are compared with each other and observations, to validate if there is an agreement in signal when moving to storm-resolving resolutions. We both show global maps of diurnal variability and local analysis at various locations with the aim to assess when and where results are sensitive to spatial resolution. We highlight new insights, but also model shortcomings that this study has revealed that need attention.

Conclusion & Results

The most important results and conclusions drawn from this report are:

Storm-resolving models are the best generation of models to date in their ability to reproduce 2-m surface air temperature, but there is a large spread in quality among the simulations.

Both ICON and IFS reproduce patterns in the energy, water, and momentum balance that resemble reality, but at the same time large descrepancies exist between the models.

ICON has considerably more net radiation at the surface than IFS, mainly driven by higher surface solar irradiance fluxes.

ICON uses more of the available energy at the surface for sensible heating and less for latent heating compared to IFS.

Both ICON, IFS and ERA5 show summer afternoon precipitation peak over the Alps earlier during the day than observed

ICON shows larger diurnal temperature ranges compared to IFS over the Alps, and IFS is in better correspondence with observations
