description: Networks are a fundamental tool for understanding and modeling complex systems in physics, biology, neuroscience, engineering, and social science. Many networks are known to exhibit rich, lower-order connectivity patterns that can be captured at the level of individual nodes and edges. However, higher-order organization of complex networks---at the level of small network subgraphs---remains largely unknown. Here we develop a generalized framework for clustering networks based on higher-order connectivity patterns. This framework provides mathematical guarantees on the optimality of obtained clusters and scales to networks with billions of edges. The framework reveals higher-order organization in a number of networks including information propagation units in neuronal networks and hub structure in transportation networks. Results show that networks exhibit rich higher-order organizational structures that are exposed by clustering based on higher-order connectivity patterns.

description: Efficient replication and assembly of virus particles are integral to the establishment of infection. In addition to the primary role of the capsid protein (CP) in encapsidating the RNA progeny, experimental evidence on positive sense single-stranded RNA viruses suggests that the CP also regulates RNA synthesis. Here, we demonstrate that replication of Satellite tobacco mosaic virus (STMV) is controlled by the cooperative interaction between STMV CP and the helper virus (HV) Tobacco mosaic virus (TMV) replicase. We identified that the STMV CP-HV replicase interaction requires a positively charged residue at the third position (3R) in the N-terminal 13 amino acid (aa) motif. Far-Northwestern blotting showed that STMV CP promotes binding between HV-replicase and STMV RNA. An STMV CP variant having an arginine to alanine substitution at position 3 in the N-terminal 13aa motif abolished replicase-CP binding. The N-terminal 13aa motif of the CP bearing alanine substitutions for positively charged residues located at positions 5, 7, 10 and 11 are defective in packaging full-length STMV, but can package a truncated STMV RNA lacking the 3' terminal 150 nt region. These findings provide insights into the mechanism underlying the regulation of STMV replication and packaging.

description: In this paper, we introduce a new model of selection behavior under risk that describes an essential cognitive process for comparing values of objects and making a selection decision. This model is constructed by the quantum-like approach that employs the state representation specific to quantum theory, which has the mathematical framework beyond the classical probability theory. We show that our quantum approach can clearly explain the famous examples of anomalies for the expected utility theory, the Ellsberg paradox, the Machina paradox and the disparity between WTA and WTP. Further, we point out that our model mathematically specifies the characteristics of the probability weighting function and the value function, which are basic concepts in the prospect theory.

description: The Coronavirus (COVID-19) pandemic affected the way U.S. consumers purchased food. The evidence is mixed on how these changes translated into dietary and nutritional outcomes. This report uses the Consumer Expenditure Diary Survey to examine food purchasing behaviors before (2016–19) and during the early onset of the COVID-19 pandemic (2020). As U.S. households shifted away from meals from full-service restaurants, they purchased more food and beverages at grocery stores and other food-at-home (FAH) establishments. Increased FAH spending was driven by higher spending on protein foods, fruits, vegetables, and other FAH (e.g., desserts, prepared meals and salads). However, these increases were uneven across food categories and subpopulations. The largest increases in the FAH share between 2016–19 and 2020 were among single households without children, non-Hispanic Asian households, and in the Northeast. The largest decreases in the food-away-from-home (FAFH) share were among non-Hispanic Asian households and in the Northeast.

description: We report optical CCD photometry of the recently identified symbiotic star EF Aql. Our observations in Johnson V and B bands clearly show the presence of stochastic light variations with an amplitude of about 0.2 mag on a time scale of minutes. The observations point toward a white dwarf (WD) as the hot component in the system. It is the 11-th object among more than 200 symbiotic stars known with detected optical flickering. Estimates of the mass accretion rate onto the WD and the mass loss rate in the wind of the Mira secondary star lead to the conclusion that less than 1 per cent of the wind is captured by the WD. Eight further candidates for the detection of flickering in similar systems are suggested.

description: Out-of-time-order (OTO) operators have recently become popular diagnostics of quantum chaos in many-body systems. The usual way they are introduced is via a quantization of classical Lyapunov growth, which measures the divergence of classical trajectories in phase space due to the butterfly effect. However, it is not obvious how exactly they capture the sensitivity of a quantum system to its initial conditions beyond the classical limit. In this paper, we analyze sensitivity to initial conditions in the quantum regime by recasting OTO operators for many-body systems using various formulations of quantum mechanics. Notably, we utilize the Wigner phase space formulation to derive an $\hbar$-expansion of the OTO operator for spatial degrees of freedom, and a large spin $1/s$-expansion for spin degrees of freedom. We find in each case that the leading term is the Lyapunov growth for the classical limit of the system and argue that quantum corrections become dominant at around the scrambling time, which is also when we expect the OTO operator to saturate. We also express the OTO operator in terms of propagators and see from a different point of view how it is a quantum generalization of the divergence of classical trajectories.

description: The factorization of amplitudes into hard, soft and collinear parts is known to be violated in situations where incoming particles are collinear to outgoing ones. This result was first derived by studying limits where non-collinear particles become collinear. We show that through an effective field theory framework with Glauber operators, these factorization-violating effects can be reproduced from an amplitude that is factorized before the splitting occurs. We confirm results at one-loop, through single Glauber exchange, and at two-loops, through double Glauber exchange. To approach the calculation, we begin by reviewing the importance of Glauber scaling for factorization. We show that for any situation where initial state and final state particles are not collinear, the Glauber contribution is entirely contained in the soft contribution. The contributions coming from Glauber operators are necessarily non-analytic functions of external momentum, with the non-analyticity arising from the rapidity regulator. The non-analyticity is critical so that Glauber operators can both preserve factorization when it holds and produce factorization-violating effects when they are present.

description: In the current work we present a new modelling approach for simulating meso-scopic phenomena related to lubrication of the piston ring-cylinder liner contact. Our geometry allows a variable confinement gap and a varying amount of lubricant in the gap, while avoiding the squeeze-out of the lubricant into vacuum. We have implemented a coarse grain molecular dynamics description of an ionic liquid as a lubricant which can expand into lateral reservoirs. The results have revealed two regimes of lubrication, an elasto-hydrodynamic one under low loads and one with low, velocity-independent specific friction, under high loads. The observed steep rise of normal forces at small plate-to-plate distances is an interesting behaviour that could potentially be exploited for preventing solid-solid contact and wear.

description: We present $\sim1-4"$ resolution Very Large Array (VLA) observations of four CH$_3$OH $J_2-J_1$-$E$ 25~GHz transitions ($J$=3, 5, 8, 10) along with 1.3~cm continuum toward 20 regions of active massive star formation containing Extended Green Objects (EGOs), 14 of which we have previously studied with the VLA in the Class~I 44~GHz and Class~II 6.7~GHz maser lines (Cyganowski et al. 2009). Sixteen regions are detected in at least one 25~GHz line ($J$=5), with 13 of 16 exhibiting maser emission. In total, we report 34 new sites of CH$_3$OH maser emission and ten new sites of thermal CH$_3$OH emission, significantly increasing the number of 25~GHz Class I CH$_3$OH masers observed at high angular resolution. We identify probable or likely maser counterparts at 44~GHz for all 15 of the 25~GHz masers for which we have complementary data, providing further evidence that these masers trace similar physical conditions despite uncorrelated flux densities. The sites of thermal and maser emission of CH$_3$OH are both predominantly associated with the 4.5 $μ$m emission from the EGO, and the presence of thermal CH$_3$OH emission is accompanied by 1.3~cm continuum emission in 9 out of 10 cases. Of the 19 regions that exhibit 1.3~cm continuum emission, it is associated with the EGO in 16 cases (out of a total of 20 sites), 13 of which are new detections at 1.3~cm. Twelve of the 1.3~cm continuum sources are associated with 6.7~GHz maser emission and likely trace deeply-embedded massive protostars.

description: A recent analysis of the Supernova Ia data claims a 'marginal' ($\sim3σ$) evidence for a cosmic acceleration. This result has been complemented with a non-accelerating $R_{h}=ct$ cosmology, which was presented as a valid alternative to the $Λ$CDM model. In this paper, we use the same analysis to show that a non-marginal evidence for acceleration is actually found. We compare the standard Friedmann models to the $R_{h}=ct$ cosmology by complementing SN Ia data with the Baryon Acoustic Oscillations, Gamma Ray Bursts and Observational Hubble datasets. We also study the power-law model which is a functional generalisation of $R_{h}=ct$. We find that the evidence for late-time acceleration is beyond refutable at a 4.56$σ$ confidence level from SN Ia data alone, and at an even stronger confidence level ($5.38σ$) from our joint analysis. Also, the non-accelerating $R_{h}=ct$ model fails to statistically compare with the $Λ$CDM having a $Δ(\text{AIC})\sim30$.

description: Small non-coding RNAs can exert significant regulatory activity on gene expression in bacteria. In recent years, substantial progress has been made in understanding bacterial gene expression by sRNAs. However, recent findings that demonstrate that families of mRNAs show non-trivial sub-cellular distributions raise the question of how localization may affect the regulatory activity of sRNAs. Here we address this question within a simple mathematical model. We show that the non-uniform spatial distributions of mRNA can alter the threshold-linear response that characterizes sRNAs that act stoichiometrically, and modulate the hierarchy among targets co-regulated by the same sRNA. We also identify conditions where the sub-cellular organization of cofactors in the sRNA pathway can induce spatial heterogeneity on sRNA targets. Our results suggest that under certain conditions, interpretation and modeling of natural and synthetic gene regulatory circuits need to take into account the spatial organization of the transcripts of participating genes.

description: The power of asteroseismology relies on the capability of global oscillations to infer the stellar structure. For evolved stars, we benefit from unique information directly carried out by mixed modes that probe their radiative cores. This third article of the series devoted to mixed modes in red giants focuses on their coupling factors that remained largely unexploited up to now. With the measurement of the coupling factors, we intend to give physical constraints on the regions surrounding the radiative core and the hydrogen-burning shell of subgiants and red giants. A new method for measuring the coupling factor of mixed modes is set up. It is derived from the method recently implemented for measuring period spacings. It runs in an automated way so that it can be applied to a large sample of stars. Coupling factors of mixed modes were measured for thousands of red giants. They show specific variation with mass and evolutionary stage. Weak coupling is observed for the most evolved stars on the red giant branch only; large coupling factors are measured at the transition between subgiants and red giants, as well as in the red clump. The measurement of coupling factors in dipole mixed modes provides a new insight into the inner interior structure of evolved stars. While the large frequency separation and the asymptotic period spacings probe the envelope and the core, respectively, the coupling factor is directly sensitive to the intermediate region in between and helps determining its extent. Observationally, the determination of the coupling factor is a prior to precise fits of the mixed-mode pattern, and can now be used to address further properties of the mixed-mode pattern, as the signature of the buoyancy glitches and the core rotation.

description: The interpretive power of the newest generation of large-volume hydrodynamical simulations of galaxy formation rests upon their ability to reproduce the observed properties of galaxies. In this second paper in a series, we employ bulge+disc decompositions of realistic dust-free galaxy images from the Illustris simulation in a consistent comparison with galaxies from the Sloan Digital Sky Survey (SDSS). Examining the size-luminosity relations of each sample, we find that galaxies in Illustris are roughly twice as large and $0.7$ magnitudes brighter on average than galaxies in the SDSS. The trend of increasing slope and decreasing normalization of size-luminosity as a function of bulge-fraction is qualitatively similar to observations. However, the size-luminosity relations of Illustris galaxies are quantitatively distinguished by higher normalizations and smaller slopes than for real galaxies. We show that this result is linked to a significant deficit of bulge-dominated galaxies in Illustris relative to the SDSS at stellar masses $\log\mathrm{M}_{\star}/\mathrm{M}_{\odot}\lesssim11$. We investigate this deficit by comparing bulge fraction estimates derived from photometry \emph{and} internal kinematics. We show that photometric bulge fractions are systematically lower than the kinematic fractions at low masses, but with increasingly good agreement as the stellar mass increases.

Carbon nanotubes are molecules made of carbon with a cylindrical structure possessing unusual valuable properties.

In the present paper, we investigate the automorphisms and the orbits of armchair nanotubes and derive the closed formulas for their Graovac-Pisanski index.

description: The transition disk around the T Tauri star T Cha possesses a large gap, making it a prime target for high-resolution imaging in the context of planet formation. We aim to find signs of disk evolutionary processes by studying the disk geometry and the dust grain properties at its surface, and to search for companion candidates. We analyze a set of VLT/SPHERE data at near-infrared and optical wavelengths. We performed polarimetric imaging of T Cha with IRDIS (1.6 $μ$m) and ZIMPOL (0.5-0.9 $μ$m), and obtained intensity images from IRDIS dual-band imaging with simultaneous spectro-imaging with IFS (0.9-1.3 $μ$m). The disk around T Cha is detected in all observing modes and its outer disk is resolved in scattered light with unprecedented angular resolution and signal-to-noise. The images reveal a highly inclined disk with a noticeable east-west brightness asymmetry. The significant amount of non-azimuthal polarization signal in the $U_ϕ$ images, with a $U_ϕ$/$Q_ϕ$ peak-to-peak value of 14%, is in accordance with theoretical studies on multiple scattering. Our optimal axisymmetric radiative transfer model considers two coplanar inner and outer disks, separated by a gap of 0.28" (~30au) in size. We derive a disk inclination of ~69 deg and PA of ~114 deg. In order to self-consistently reproduce the intensity and polarimetric images, the dust grains, responsible for the scattered light, need to be dominated by sizes of around ten microns. A point source is detected at an angular distance of 3.5" from the central star. It is, however, found not to be co-moving. We confirm that the dominant source of emission is forward scattered light from the near edge of the outer disk. Our point source analysis rules out the presence of a companion heavier than ~8.5 $M_{\mathrm{jup}}$ between 0.1" and 0.3". The detection limit decreases to ~2 $M_{\mathrm{jup}}$ for 0.3" to 4.0".

description: Let $\{f_t\}$ be a family of complex polynomial functions with line singularities. We show that if $\{f_t\}$ has a uniform stable radius (for the corresponding Milnor fibrations), then the Lê numbers of the functions $f_t$ are independent of $t$ for all small $t$. In the case of isolated singularities --- a case for which the only non-zero Lê number coincides with the Milnor number --- a similar assertion was proved by M. Oka and D. O'Shea. By combining our result with a theorem of J. Fernández de Bobadilla --- which says that families of line singularities in $\mathbb{C}^n$, $n\geq 5$, with constant Lê numbers are topologically trivial --- it follows that a family of line singularities in $\mathbb{C}^n$, $n\geq 5$, is topologically trivial if it has a uniform stable radius. As an important example, we show that families of weighted homogeneous line singularities have a uniform stable radius if the nearby fibres $f_t^{-1}(η)$, $η\not=0$, are "uniformly" non-singular with respect to the deformation parameter $t$.

description: In 2010, the Government set out its commitment to establish a national non-emergency police number for England and Wales which would provide a single, memorable non-emergency number for contacting the police (101).

 This study reviewed the extent to which the 101 service was operating as intended in some of the first forces to implement 101. The study also examined call handling of non-emergency incidents more generally, including public perceptions and expectations of how non-emergency incidents should be dealt with.

 Interviews with national and local stakeholders as well as members of the public who had used the 101 service were undertaken. These were supplemented by focus groups with the public to understand wider attitudes to contacting the police.
The first Baade-Wesselink analysis of Blazhko RR Lyrae stars: discrepancies between photometrically and spectroscopically determined radius variations

description: The simultaneous photometric and spectroscopic observations of the RR Lyrae variables in the globular cluster, M3, published in Jurcsik et al. (2017, Paper I) made it possible to perform Baade-Wesselink (BW) analysis of a large sample of Blazhko stars for the first time. The BW distances of Blazhko stars turned out to be unreliable, as significantly different distances were obtained for the stars of the Blazhko sample and also for the same star in different modulation phases. Even the results of small modulation-amplitude Blazhko stars may be doubtful. This result warns that the application of the BW method to Blazhko stars is not trustworthy. Keeping the distance fixed for each Blazhko star in each modulation phase, a significant difference between the spectroscopic and the photometric radius ($R_{\textrm{sp}}$, $R_{\textrm{ph}}$) variations is detected. The phase and amplitude variations of $R_{\textrm{sp}}$ follow the changes of the light curve during the Blazhko cycle but the $R_{\textrm{ph}}$ curve seems to be not (or only marginally) affected by the modulation. The asynchronous behaviour of $R_{\textrm{sp}}$ and $R_{\textrm{ph}}$ supports the interpretation of the Blazhko effect as a depth-dependent phenomenon, as the spectroscopic radius variation reflects the radial displacement of the line-forming region high in the atmosphere, while the photospheric radius variation is derived from the information of the observed visual-band light emitted mostly by the lower photosphere. The stability of $R_{\textrm{ph}}$ may be interpreted as a strong argument against the non-radial-mode explanation of the Blazhko phenomenon.

description: A selected sample of this study, listed under SN 6512: Affluent Worker in the Class Structure, 1961-1962, is available via the UK Data Service Qualibank, an online tool for browsing, searching and citing the content of selected qualitative data collections held at the UK Data Service.

 The 'Affluent Worker' project was undertaken to test empirically the thesis of working class embourgeoisement. Conducted in the early 1960s, the empirical study consisted of interviews with manual workers and their wives. The original project was exploring the social and cultural influences on manual workers’ class identities. Although the researchers rejected the original embourgeoisement thesis that working class people were becoming assimilated to the middle classes, they did argue that traditional working class norms had been adapted in the post war period of prosperity. They found that in place of assimilation ‘major on-going modification in manual-non manual differences were occurring at the level of values and aspirations’ (Goldthorpe et al. 1969:26).

 The research studied the attitudes and behaviour of high wage earners in three mass or continuous flow companies. During 1961-1962, married, male workers from three Luton factories (Vauxhall, Skefco and Laporte) were firstly interviewed at work and then, again, at home with their wives. Additionally, a sample of middle-class, white-collar workers from the same companies were interviewed only at home. A pilot of the study was conducted in Cambridge prior to the main Luton study.

 This Special License issue contains an additional 213 surveys from the Luton area and 12 more data files from the Cambridge area. A subset of the Luton study interviews was digitised and formed part of a wider ESRC project Living Standards, social identities and the working class in England, c.1945-c.1970. For this subset, 30 married male Vauxhall workers' completed questionnaires were selected from boxes 01 and 02 from the full collection, as the handwriting on the original papers was legible, and follow-up home interviews were available as well as the initial workplace interview. The resulting data have been collated into tabular form, within an MS Access database. The tables replicate the structure and variables of the questionnaires used in the original study. Street, place and personal names were standardised by the original investigators, and care has been taken to retain original spellings. The subset database therefore contains a total of 60 interviews, each with 464 variables.

description: We perform an in-depth study of some domination and smoothing properties of linear operators and of their role within the theory of eventually positive operator semigroups. On the one hand we prove that, on many important function spaces, they imply compactness properties. On the other hand, we show that these conditions can be omitted in a number of Perron--Frobenius type spectral theorems. We furthermore prove a Kre\uın--Rutman type theorem on the existence of positive eigenvectors and eigenfunctionals under certain eventual positivity conditions.
Structural connectivity and task-evoked dynamics of the default mode network
Creators: name: Mastrovito, Dana
Publisher: name: No Publisher Supplied

description: The default mode network (DMN) is a structurally interconnected network of brain regions defined collectively by their high level of intrinsic activity at “rest” and relative decrease in activity while performing a range of cognitive tasks. The functional role of the network's intrinsic activity, as well as the significance of its task-evoked attenuation is unknown. However, aberrations in DMN activity are implicated in many disorders including Alzheimers, depression, autism, and schizophrenia, suggesting it may have a fundamental role in healthy brain function. Using diffusion imaging, I trace the large-scale anatomical connections of the network through the basal ganglia and thalamus, illustrating that the core regions of the network form a distributed cortico-striatal-thalamic circuit. Using Markov chain models of functional MRI, I explore the temporal dynamics of each region of the network during task execution and and present evidence suggesting the DMN may orchestrate switching between bottom up and top down processing in the brain through its connections to the basal ganglia. Subcomponents of the network in parietal cortex may support bottom-up processing while anterior portions in medial prefrontal cortex facilitate top-down. Finally, I classify resting-state data from patients with autism and schizophrenia and find that changes in DMN activity are potential biomarkers for distinguishing between the two disorders.

description: In this paper we present a new class of dynamical system without equilibria which possesses a multi scroll attractor. It is a piecewise-linear (PWL) system which is simple, stable, displays chaotic behavior and serves as a model for analogous non-linear systems. We test for chaos using the 0-1 Test for Chaos of Ref.12.

description: We study the consistency and convergence of smoothed particle hydrodynamics (SPH), as a function of the interpolation parameters, namely the number of particles $N$, the number of neighbors $n$, and the smoothing length $h$, using simulations of the collapse and fragmentation of protostellar rotating cores. The calculations are made using a modified version of the GADGET-2 code that employs an improved scheme for the artificial viscosity and power-law dependences of $n$ and $h$ on $N$, as was recently proposed by Zhu et al., which comply with the combined limit $N\to\infty$, $h\to 0$, and $n\to\infty$ with $n/N\to 0$ for full SPH consistency, as the domain resolution is increased. We apply this realization to the "standard isothermal test case" in the variant calculated by Burkert & Bodenheimer and the Gaussian cloud model of Boss to investigate the response of the method to adaptive smoothing lengths in the presence of large density and pressure gradients. The degree of consistency is measured by tracking how well the estimates of the consistency integral relations reproduce their continuous counterparts. In particular, $C^{0}$ and $C^{1}$ particle consistency is demonstrated, meaning that the calculations are close to second-order accuracy. As long as $n$ is increased with $N$, mass resolution also improves as the minimum resolvable mass $M_{\rm min}\sim n^{-1}$. This aspect allows proper calculation of small-scale structures in the flow associated with the formation and instability of protostellar disks around the growing fragments, which are seen to develop a spiral structure and fragment into close binary/multiple systems as supported by recent observations.

description: III-V nanostructures have the potential to revolutionize optoelectronics and energy harvesting. For this to become a reality, critical issues such as reproducibility and sensitivity to defects should be resolved. By discussing the optical properties of MBE grown GaAs nanomembranes we highlight several features that bring them closer to large scale applications. Uncapped membranes exhibit a very high optical quality, expressed by extremely narrow neutral exciton emission, allowing the resolution of the more complex excitonic structure for the first time. Capping of the membranes with an AlGaAs shell results in a strong increase of emission intensity but also to a shift and broadening of the exciton peak. This is attributed to the existence of impurities in the shell, beyond MBE-grade quality, showing the high sensitivity of these structures to the presence of impurities. Finally, emission properties are identical at the sub-micron and sub-millimeter scale, demonstrating the potential of these structures for large scale applications.

description: Approximately 209,000 women report being raped every year. Of those 209,000 rapes, only 19,491 arrests were made (U.S. Department of Justice 2011). Furthermore, reports estimate that one out of every three women will be raped at some point in her life (Amir, 1971). The prominence ofrape in the United States, as well as the disparity between documented rapes to the police and victim reports of rape, is problematic for researchers in fully understanding the breadth of the problem. Considering that rape occurs at such an overwhelmingly high rate and frequently goes unreported, it is important to understand the attitudes and social norms that foster victim blame and reluctance of rape victims to report. Some individuals believe certain cultural stereotypes, known as rape myths, which are pervasive in the United States and foster rape acceptance and victim blame. The underlying belief system which may be attributing to these cultural beliefs is just world beliefs, which asserts that everyone gets what he or she deserves in life. Such a belief system encourages support for rape myths and other victim blaming attitudes, which inhibits victims from recovering, deters victims from reporting and prevents rapists from being appropriately punished. Prior research regarding rape myths and just world beliefs is rather dated, hence the need for more contemporary research regarding the relationship between the two. The current research builds upon and extends previous research, specifically the work of Carmody and Washington (2001), by examining the relationship between rape myth acceptance, just world beliefs, prior victimization, age, education and ethnicity.

It was hypothesized that older more educated individuals would have a lower acceptance of rape myths than younger, less educated individuals. It was also hypothesized that those who scored higher on the just world belief scale would score higher on the rape myth acceptance scale. Furthermore, it was believed that rape victims would score higher on the rape myth acceptance scale than non-victims. All hypotheses were supported with one exception: rape victims did not have higher levels of rape myth acceptance than nonvictims.

description: Semi-Dirac semimetal is a material exhibiting linear band dispersion in one direction and quadratic band dispersion in the orthogonal direction and, therefore, hosts massless and massive fermions at the same point in the momentum space. While a number of interesting physical properties have been predicted in semi-Dirac semimetals, it has been rare to realize such materials in condensed matters. Based on the fact that some honeycomb materials are easily oxidized or chemically absorb other atoms, here, we theoretically propose an approach of modifying their band structures by covalent addition of group-VI elements and strain engineering. We predict a silicene oxide with chemical formula of Si2O to be a candidate of semi-Dirac semimetal. Our approach is backed by the analysis and understanding of the effect of p-orbital frustration on the band structure of the graphene-like materials.

description: Advances in molecular biology are enabling rapid and efficient analyses for effective intervention in domains such as biology research, infectious disease management, food safety, and biodefense. The emergence of microfluidics and nanotechnologies has enabled both new capabilities and instrument sizes practical for point-of-care. It has also introduced new functionality, enhanced sensitivity, and reduced the time and cost involved in conventional molecular diagnostic techniques. This chapter reviews the application of microfluidics for molecular diagnostics methods such as nucleic acid amplification, next-generation sequencing, high resolution melting analysis, cytogenetics, protein detection and analysis, and cell sorting. We also review microfluidic sample preparation platforms applied to molecular diagnostics and targeted to sample-in, answer-out capabilities.

description: During February 2016, CSIRO Astronomy and Space Science and the Max-Planck-Institute for Radio Astronomy installed, commissioned and carried out science observations with a phased array feed (PAF) receiver system on the 64m diameter Parkes radio telescope. Here we demonstrate that the PAF can be used for pulsar observations and we highlight some unique capabilities. We demonstrate that the pulse profiles obtained using the PAF can be calibrated and that multiple pulsars can be simultaneously observed. Significantly, we find that an intrinsic polarisation leakage of -31dB can be achieved with a PAF beam offset from the centre of the field of view. We discuss the possibilities for using a PAF for future pulsar observations and for searching for fast radio bursts with the Parkes and Effelsberg telescopes.

description: The Coronavirus (COVID-19) pandemic caused significant disruption to U.S. meat supply chains in the spring and summer of 2020, according to a recent USDA, Economic Research Service report. In the early months of the pandemic, COVID-19 infections caused worker absences at beef packing plants, leading to a slowdown in slaughter rates and even some temporary plant shutdowns. From mid-April to mid-June 2020, the decrease in slaughter rates—combined with a surge in retail demand—drove a historically wide gap between wholesale meat and livestock prices. Wholesale beef prices rose, while cattle prices remained low. The price changes affected the entire supply chain. Cattle producers struggled with low prices for their market-ready animals and consumers paid more for beef at grocery stores.
