description: We conducted a multi-wavelength campaign in September-October, 2002, to observe SS 433. We used 45 meter sized 30 dishes of Giant Meter Radio Telescope (GMRT) for radio observation, 1.2 meter Physical Research Laboratory Infra-red telescope at Mt Abu for IR, 1 meter Telescope at the State Observatory, Nainital for Optical photometry, 2.3 meter optical telescope at the Vainu Bappu observatory for spectrum and Rossi X-ray Timing Explorer (RXTE) Target of Opportunity (TOO) observation for X-ray observations. We find sharp variations in intensity in time-scales of a few minutes in X-rays, IR and radio wavelengths. Differential photometry at the IR observation clearly indicated significant intrinsic variations in short time scales of minutes throughout the campaign. Combining results of these wavelengths, we find a signature of delay of about two days between IR and Radio. The X-ray spectrum yielded double Fe line profiles which corresponded to red and blue components of the relativistic jet. We also present the broadband spectrum averaged over the campaign duration.

description: Restricted-valence random sequential adsorption~(RSA) is studied in its pure and disordered versions, on the square and triangular lattices. For the simplest case~(pure on the square lattice) we prove the absence of percolation for maximum valence $V_{\rm max}=2$. In other cases, Monte Carlo simulations are used to investigate the percolation threshold, universality class, and jamming limit. Our results reveal a continuous transition for the majority of the cases studied. The percolation threshold is computed through finite-size scaling analysis of seven properties; its value increases with the average valency. Scaling plots and data-collapse analyses show that the transition belongs to the standard percolation universality class even in disordered cases

description: We address the issue of radiative corrections to Kaluza-Klein (KK) masses in five-dimensional QED supplemented by aether Lorentz-violating terms. Specifically, we compute the corrections to the KK photon masses from one fermion loop. In general, the KK masses receive radiative corrections due to breaking the five-dimensional Lorentz invariance by compactification. As we show, the presence of the additional Lorentz violating factor - an aether background, leads to the non-trivial modification of these corrections. This model may be of interest in addressing important phenomenological issues such as the relation between radiative corrected KK mass splitting of a particular mode and uncertainties in the measurements and/or possible spatial variation of the fine-structure constant. For the recent data on the fine-structure constant, we find a KK mass splitting of magnitude $\sim 0.01$ MeV for the first excited Kaluza-Klein gauge boson at TeV scale. On the other hand, the large KK modes limit displays a very interesting phenomenon, showing the very special role of the aether in protecting the higher modes from the quantum corrections.

Photoluminescence from MEH-PPV and DP-PPV in bulk and encapsulated in porous alumina
Creators: name: Qi, Dong Feng
Publisher: name: University of British Columbia
Year: 2009

description: Two PPV derivatives, MEH-PPV and DP-PPV, are encapsulated in the nanopores of anodized alumina with different pore sizes (50/200 nm) and depth (10/60 urn). Time-integrated and time resolved optical emission properties of these structures have been studied and compared with those of thin films of the polymers. Significant blue shifts of the PL spectra (0.034 eV-0.183 eV) are found in the porous materials as compared to the bulk. The relative intensity of the one-phonon assisted transition increases in comparison with the intensity of the no-phonon transition in the nanostructured samples. The time constants of the optical emission from the bulk MEH-PPV film are very similar in their energy dependence to results obtained previously on bulk PPV films when considered with respect to the excess energy above the peak of the emission spectrum. The decay times are, however, two to three times shorter in the parent. The energy dependence of the time constants measured in DP-PPV films and DP-PPV encapsulated in nanopores (pore diameter 200 nm, pore depth 60 um) are also very similar to each other, and to the results obtained on the MEH-PPV. These results suggest that the intrachain diffusion of electron-hole excitations in all of these polymers, either in bulk or encapsulated form, is very similar.
Charge radii of exotic neon and magnesium isotopes

description: We compute the charge radii of even-mass neon and magnesium isotopes from neutron number N = 8 to the dripline. Our calculations are based on nucleon-nucleon and three-nucleon potentials from chiral effective field theory that include delta isobars. These potentials yield an accurate saturation point and symmetry energy of nuclear matter. We use the coupled-cluster method and start from an axially symmetric reference state. Binding energies and two-neutron separation energies largely agree with data and the dripline in neon is accurate. The computed charge radii have an estimated uncertainty of about 2-3% and are accurate for many isotopes where data exist. Finer details such as isotope shifts, however, are not accurately reproduced. Chiral potentials correctly yield the subshell closure at N = 14 and also a decrease in charge radii at N = 8 (observed in neon and predicted for magnesium). They yield a continued increase of charge radii as neutrons are added beyond N = 14 yet underestimate the large increase at N = 20 in magnesium.

description: In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation can open the possibility to widely tune the band structure of 2D materials. In particular, we demonstrate the controlled oxidation of titanium trisulfide (TiS$_3$), a layered semiconductor that has attracted much attention recently thanks to its quasi-1D electronic and optoelectronic properties and its direct bandgap of 1.1 eV. Heating TiS$_3$ in air above 300 °C gradually converts it into TiO$_2$, a semiconductor with a wide bandgap of 3.2 eV with ap-plications in photo-electrochemistry and catalysis. In this work, we investigate the controlled thermal oxidation of individual TiS$_3$ nanoribbons and its influence on the optoelectronic properties of TiS$_3$-based photodetectors. We observe a step-wise change in the cut-off wavelength from its pristine value ~1000 nm to 450 nm after subjecting the TiS$_3$ devices to subsequent thermal treatment cycles. Ab-initio and many-body calculations confirm an increase in the bandgap of titanium oxysulfide (TiO$_{2-x}$S$_x$) when increasing the amount of oxygen and reducing the amount of sulfur.

subject: food safety

description: Consumers' attitudes to trust and risk are key issues in food safety research and attention needs to be focused on clearly defining a framework for analysing consumer behaviour in these terms. By creating a platform, or benchmark, it is hoped that more succinct policy programmes may be initiated to better communicate relevant issues to consumers. In order to achieve this, a detailed review of the recent literature surrounding risk, trust and, the relationship between the two must be conducted. This paper aims to collate the literature in the fields of consumer attitudes to trust and risk. It provides an insight into the economic and other modelling procedures available to measure consumers' attitudes to risk and trust in food safety and specifically notes the need for future research to concentrate on examining risk and trust as highly related variables rather than two distinct concepts.

description: This paper focuses on estimating consumers' willingness to pay for and willingness to accept irradiated food using a non-hypothetical experiment utilizing real food products (i.e., irradiated ground beef), real cash, and actual exchange in a market setting. Single-bounded and one and one-half bounded models are developed using dichotomous choice contingent valuation experiments. Our results indicate that average willingness to pay values range from 75.43 to 78.51 cents per pound while average willingness to accept values range from 69.49 to 81.63 cents per pound of irradiated ground beef.

description: Particles inside a planetary ring are subject to forcing due to the central planet, moons in inclined orbits, self-gravity of the ring and other forces due to radiation drag, collisional effects and Lorentz force due to magnetic field of the planet. We write down the equations of motion of a single particle inside the ring and solve them analytically. We find that the importance of the shear caused by variation of the radial velocity component with local vertical direction cannot be ignored and it may be responsible for damping of the bending waves in planetary rings as observed by the Voyager data. We present the wave profile resulting from the dissipation. We estimate that the surface mass density of the C ring to be of the order of $σ\sim 1.2-1.6$gm cm$^{-2}$, and the height $h \sim 2.2-2.4$m. These theoretical results are in agreement with observations.

The synthesized films are characterized by a combination of complementary techniques: Raman spectroscopy, X-ray diffraction, transmission electron microscopy and electronic transport measurements.

We investigate the adequacy of the theoretical models in explaining the measured experimental data and we determine the contributions of multi-step direct and multi-step compound processes in the formation of the cross-sections. We show that the traditional frameworks are valid for the description of the new experimental data and our measurements are in agreement with the previous measurements for the (p,xp) and (p,x$α$) reactions on the $^{54}$Fe nucleus. The only exception is within the energy region of E$_{p}$=15 and 25 MeV for both reactions, where the cross-section for the $^{56}$Fe nucleus is smaller than the cross-section for the $^{54}$Fe nucleus.

description: Artificial lattices of coherently coupled macroscopic states are at the heart of applications ranging from solving hard combinatorial optimisation problems to simulating complex many-body physical systems. The size and complexity of the problems scales with the extent of coherence across the lattice. Although the fundamental limit of spatial coherence depends on the nature of the couplings and lattice parameters, it is usually engineering constrains that define the size of the system. Here, we engineer polariton condensate lattices with active control on the spatial arrangement and condensate density that result in near-diffraction limited emission, and spatial coherence that exceeds by nearly two orders of magnitude the size of each individual condensate. We utilise these advancements to unravel the dependence of spatial correlations between polariton condensates on the lattice geometry.

description: This paper studies multiple attributes of pork production and analyses the trade-offs that consumers make between them. Results show that without considering the trade-offs, animal welfare and food safety are on average perceived as the most important attributes. However, including trade-offs, Taste and Price become major concerns. Conclusions are nuanced as for a number of segments and specific trade-offs Taste and Price are relatively less important. Results support the implementation of differentiated chain designs with distinct and innovative decisions for trade-offs to be made.

description: Using the Danish broiler sector and an ongoing food quality project as a case study, the paper provides a dicussion of how new food safety and food quality standards might be implemented. In the paper the design of new payment schemes is seen as an important part of the realignment of the poultry supply chain. The basic principles of such a new scheme is outlined and suggestions for a redesign of the incentive structures are discussed. Furthermore economic and organizational issues, related to the structural realignment of the supply chain raised by the development and implementation of a chain-wide HACCP system, are discussed. It is concluded that successfully implementation of HACCP principles in a sector as a whole, not only is a matter of describing procedures and formulation of sanitary and safety requirements.

description: Our recent radio observation using the Giant Meter Radio Telescope (GMRT) of the galactic black hole transient A0620-00 at 1.280GHz revealed a micro-flare of a few milli-Jansky. Assuming an equipartition of magnetic energy and the gravitational potential energy of accreting matter, it is possible to estimate the upper limit of the accretion rate. Assuming a black hole mass of $10M_\odot$ residing at the center, we find this to be at the most ${\dot M} = (8.5 \pm 1.4) \times 10^{-11} M_\odot$ yr$^{-1}$. This is consistent with earlier estimates of accretion rates based on optical and X-ray observations.

description: We introduce a mesoscopic three-dimensional Lattice Boltzmann Model which attempts to mimick the physical features associated with cage effects in dynamically heterogeneous fluids. To this purpose, we extend the standard Lattice Boltzmann dynamics with self-consistent constraints based on the non-local density of the surrounding fluid. The resulting dynamics exhibits typical features of dynamic heterogeneous fluids, such as non-Gaussian density distributions and long-time relaxation. Due to its intrinsically parallel dynamics, and absence of statistical noise, the method is expected to compute significantly faster than molecular dynamics, Monte Carlo and lattice glass models.

description: To represent motions from a mechanical point of view, this paper explores motion embedding using the motion taxonomy. With this taxonomy, manipulations can be described and represented as binary strings called motion codes. Motion codes capture mechanical properties, such as contact type and trajectory, that should be used to define suitable distance metrics between motions or loss functions for deep learning and reinforcement learning. Motion codes can also be used to consolidate aliases or cluster motion types that share similar properties. Using existing data sets as a reference, we discuss how motion codes can be created and assigned to actions that are commonly seen in activities of daily living based on intuition as well as real data. Motion codes are compared to vectors from pre-trained Word2Vec models, and we show that motion codes maintain distances that closely match the reality of manipulation.

description: The objective of this paper is to assess food systems performance in Mediterranean countries to deliver safe food (fresh produce), and to demonstrate the capacity to the satisfaction of private customers and public regulators. To that end, an international benchmarking exercise was developed to assess the quality performance gap in food standards across countries and food systems. The study was carried out in three Mediterranean countries: Spain, Morocco and Turkey and involved an audit of the citrus and tomatoes supply chains, and a comparison with existing "best practice" in infrastructure and management practices at both firm and industry level. The aim was to identify the gaps between fresh produce exporters and a best practice company. To that end, the Spanish fresh produce supply chain was used as the benchmark since in many areas it is more advanced than elsewhere.

subject: food safety

description: The BSE crisis has increased consumers' concerns on beef safety. Product quality systems and controls have been reinforced. Traceability certification and quality labels have been developed to communicate consumers the safety characteristics of the labelled beef and recover consumption. As a consequence, production costs have increased, which have been ultimately transmitted to consumer prices. The objective of this paper is to develop a conceptual model able to analyse main factors influencing consumers' willingness-to-pay for certified beef. A three-equation recursive model is jointly estimated. Results indicate that income, level of beef consumption, the average price consumers paid for beef and beef safety perception are main determinants of Spanish consumers' willingness- to-pay for certified beef.

description: Tidal effects in planetary systems are the main driver in the orbital migration of natural satellites. They result from physical processes occurring deep inside celestial bodies, whose effects are rarely observable from surface imaging. For giant planet systems, the tidal migration rate is determined by poorly understood dissipative processes in the planet, and standard theories suggest an orbital expansion rate inversely proportional to the power 11/2 in distance, implying little migration for outer moons such as Saturn's largest moon, Titan. Here, we use two independent measurements obtained with the Cassini spacecraft to measure Titan's orbital expansion rate. We find Titan migrates away from Saturn at 11.3 $\pm$ 2.0 cm/year, corresponding to a tidal quality factor of Saturn of Q $\simeq$ 100, and a migration timescale of roughly 10 Gyr. This rapid orbital expansion suggests Titan formed significantly closer to Saturn and has migrated outward to its current position. Our results for Titan and five other moons agree with the predictions of a resonance locking tidal theory, sustained by excitation of inertial waves inside the planet. The associated tidal expansion is only weakly sensitive to orbital distance, motivating a revision of the evolutionary history of Saturn's moon system. The resonance locking mechanism could operate in other systems such as stellar binaries and exoplanet systems, and it may allow for tidal dissipation to occur at larger orbital separations than previously believed.

description: Safety of the street foods is an important aspect in the field of nutrition security. A study was conducted in the city of Varanasi in India. It was observed that about 42% of the working man and women in the age group of 25-45, and 61% of the students in the age group of 14-21, consume foods from the street vendors in the day at least once. About 23% of working women prefer to have food from street vendors rather carrying food from home to the work place. About 82 % of people of all age groups prefer to go to street vendors against only 18% only who prefer to go to the restaurant in the evening. About 57% working man and women are concerned about the cleanliness and hygiene of the vendors while the rest are not concerned about these aspects.

description: In Hungary the introduction of quality assurance and food safety systems have achieved considerable results in the middle of the food-supply chain (i.e. in companies of food industry and trade sector), but in the ends of the chain (in agriculture and catering sector) there are still several problems. This article and our presentation wish to show a general overview on the Hungarian milk sector, to describe the present situation of the Hungarian dairy farms and try to explore and examine the main difficulties of the building-up process, installation and operation of HACCP System in the Hungarian fresh milk producing sector and, furthermore its opportunities and threats, too. We also give a short description of the Hungarian dairy sector, the main Hungarian and EU quality standards of fresh milk and the main regulations of milk quality in Hungary and the European Union. In the final part of our article we wish to present a cost-benefit calculation model calculated for the Józsefmajor Experimental and Demonstration Farm, (a demonstration farm of the Szent István University) where the HACCP System was installed in the last year, and also to determine the strengths and weaknesses and some practical experiences of installation and operation of the system. The situation outlined in our paper is not unique, it can be applied to the greatest proportion of Hungarian dairy farms.

description: In this paper, creativity of students in interdisciplinary (ID) teams during the divergent (brainstorming and idea generation) phase is studied. The background of the students varied between undergraduate and graduate studies, and the creativity was stimulated amidst a discussion involving innovative solutions for the future of existing technologies In addition, the effect of knowledge heterogeneity and -synthesis is discussed. The study is conducted via a survey among the participants of the Delft/CERN IdeaSquare eSummer School 2020, held online from June 2020 to August 2020. The surveyed cohort was asked about the quantity of the generated ideas and their agreement to different statements, regarding size of the knowledge gap, effort to communicate and provide feedback, enjoyment, productivity and composition of their teams. The majority of the responding students believed they would produce the same or more ideas in ID teams, compared to that during monodisciplinary team work. We compared the agreement (between 0% and 100%) with the number of individual ideas and found a correlation for each mentioned category. This study is a first step to show that ID teams in a technological setting can be more productive. Further research should be done to repeat the experiment in a more controlled environment and solidify the hypothesis.

description: Understanding the explosion mechanism of core collapse supernovae is a problem that has plagued nuclear astrophysicists since the first computational models of this phenomenon were carried out in the 1960s. Our current theories of this violent phenomenon center around multi-dimensional effects involving radiation-hydrodynamic flows of hot, dense matter and neutrinos. Modeling these multi-dimensional radiative flows presents a computational challenge that will continue to stress high-performance computing beyond the teraflop to the petaflop level. In this paper we describe a few of the scientific discoveries that we have made via terascale computational simulations of supernovae under the auspices of the SciDAC-funded Terascale Supernova Initiative.

description: Desirable difficulties such as generating one’s own solution instead of replicating a provided solution is associated with improved long-term memory. Disseminating misleading information has shown improved learning in science education over consuming concise and clear learning instructions. We describe an experimental setup aimed at quantifying if a tutorial about programming a mobile autonomous robot that requires having to correct misleading instructions leads to better problem-solving capabilities than providing correct and clear tutorial instructions when asked to solve a complicated open-ended robotics task. The presented experimental setup is aimed towards a controlled comparative human-subject study that compares the effect of desirable difficulties on participant’s performance in solving a complicated open-ended task after completing an introductory tutorial. We explain the experiment timeline, the tasks of the tutorial, as well as the open-ended task including the robot and how this experiment can be executed under very controlled, repeatable and as unbiased as possible conditions. We share and qualitatively discuss some observed problems in this setup from early trials with 8 participants.

description: In this paper, we consider the problem of planar graph-based simultaneous localization and mapping (SLAM) that involves both poses of the autonomous agent and positions of observed landmarks. We present CPL-SLAM, an efficient and certifiably correct algorithm to solve planar graph-based SLAM using the complex number representation. We formulate and simplify planar graph-based SLAM as the maximum likelihood estimation (MLE) on the product of unit complex numbers, and relax this nonconvex quadratic complex optimization problem to convex complex semidefinite programming (SDP). Furthermore, we simplify the corresponding complex semidefinite programming to Riemannian staircase optimization (RSO) on the complex oblique manifold that can be solved with the Riemannian trust region (RTR) method. In addition, we prove that the SDP relaxation and RSO simplification are tight as long as the noise magnitude is below a certain threshold. The efficacy of this work is validated through applications of CPL-SLAM and comparisons with existing state-of-the-art methods on planar graph-based SLAM, which indicates that our proposed algorithm is capable of solving planar graph-based SLAM certifiably, and is more efficient in numerical computation and more robust to measurement noise than existing state-of-the-art methods. The C++ code for CPL-SLAM is available at https://github.com/MurpheyLab/CPL-SLAM.

Risk and Uncertainty

description: This paper presents an analysis of food risk perceptions of German consumers over the eleven year period from 1992 to 2002. Using factor analysis, we analyse the respondents general risk attitudes and the specific perception of food safety risks. General risk attitude are described by variables relating to environmental, lifestyle and food risks. Food safety concerns are grouped into concern about use of biotechnology, about residues, about unhealthy eating habits, and about natural contaminants. An ordered probit analysis identifies the characteristics that explain the importance consumers attribute to these different food safety risks. The results reveal that general risk perceptions and knowledge about food safety hazards are highly significant in the explanation.
59. Supernovae with Gaia
Creators: name: Perryman, Michael
Publisher: name: Zenodo
Year: 2022

description: Supernovae are dramatic and violent end-points of stellar evolution, and several thousand should be detected. But the physics of the progenitor star, and the evidence that each supernova leaves behind, are also rich in diagnostics: of neutron stars, black holes, and millisecond pulsars. We look at some of this forensic evidence being discovered by Gaia.
