description: The most distant Kuiper belt objects exhibit the clustering in their orbits, and this anomalous architecture could be caused by Planet 9 with large eccentricity and high inclination. We then suppose that the orbital clustering of minor planets may be observed somewhere else in the solar system. In this paper, we consider the over 7000 Jupiter Trojans from the Minor Planet Center, and find that they are clustered in the longitude of perihelion $\varpi$, around the locations $\varpi_{\mbox{J}}+60^{\circ}$ and $\varpi_{\mbox{J}}-60^{\circ}$ ($\varpi_{\mbox{J}}$ is the longitude of perihelion of Jupiter) for the L4 and L5 swarms, respectively. Then we build a Hamiltonian system to describe the associated dynamical aspects for the co-orbital motion. The phase space displays the existence of the apsidally aligned islands of libration centered on $Δ\varpi=\varpi-\varpi_{\mbox{J}}\approx\pm60^{\circ}$, for the Trojan-like orbits with eccentricities $e<0.1$. Through a detailed analysis, we have shown that the observed Jupiter Trojans with proper eccentricities $e_p<0.1$ spend most of their time in the range of $|Δ\varpi|=0-120^{\circ}$, while the more eccentric ones with $e_p>0.1$ are too few to affect the orbital clustering within this $Δ\varpi$ range for the entire Trojan population. Our numerical results further prove that, even starting from a uniform $Δ\varpi$ distribution, the apsidal alignment of simulated Trojans similar to the observation can appear on the order of the age of the solar system. We conclude that the apsidal asymmetric-alignment of Jupiter Trojans is robust, and this new finding can be helpful to design the survey strategy in the future.

description: Gas and dust in inclined orbits around binaries experience precession induced by the binary gravitational torque. The difference in precession between gas and dust alters the radial drift of weakly coupled dust and leads to density enhancements where the radial drift is minimised. We explore this phenomenon using 3D hydrodynamical simulations to investigate the prominence of these `dust traffic jams' and the evolution of the resulting dust sub-structures at different disc inclinations and binary eccentricities. We then derive evolution equations for the angular momentum of warped dust discs and implement them in a 1D code and present calculations to further explain these traffic jams. We find that dust traffic jams in inclined circumbinary discs provide significant dust density enhancements that are long lived and can have important consequences for planetesimal formation.

description: The relevance of the category "working time" is also associated with the fact that the working time itself and the time of rest are associated with such institutions as wages and labor rationing, workload, labor discipline, and labor protection. It is necessary to provide an economic and legal justification for the regulation and formation of tools for the use of working time, both on the part of employees and on the part of employers. Consequently, the object of scientific research in the study of working time processes are socio-economic and labor relations concerning the formation and use of working time. The dynamics of the efficiency of using working time in the national economy makes it possible to determine the prospects for the growth of socio-economic development from the quality and quantity of the resource of labor and time used.

description: Black holes could be produced at the Large Hadron Collider in TeV-scale gravity scenarios. We discuss missing energy mechanisms in black hole production and decay in large extra-dimensional models. In particular, we examine how graviton emission into the bulk could give the black hole enough recoil to leave the brane. Such a perturbation would cause an abrupt termination in Hawking emission and result in large missing-energy signatures.

A comparative morphological study of muscle spindles in the avian anterior and posterior latissimus dorsi muscles
Creators: name: Hatfield, Linda Jean
Publisher: name: University of British Columbia
Year: 2010

description: A study of muscle spindles in two synergistic avian muscles was undertaken to determine whether morphological or quantitative differences existed between muscle spindles residing in a slow-red (tonic) muscle and a fast-white (twitch) muscle. The avian anterior (ALD) and posterior (PLD) latissimus dorsi muscles were chosen since they are unique among vertebrates as paradigms of a slow-red and a fast-white muscle respectively. Serial frozen sections of muscle were stained with Haematoxylin and Eosin or Gomori triehrome and muscle spindles residing in the ALD were assessed and compared with those in the PLD with regard to organization, distribution and density, Contents of muscle spindles were examined for intrafusal fibre size, number and morphology. Attention was also directed to the relationship between muscle spindles and the surrounding extrafusal muscle in which they were located. Differences were found between muscle spindles residing in the two muscles. In the slow ALD, muscle spindles were relatively evenly distributed, whereas in the fast PLD, they were concentrated around the single nerve entry point into the muscle. The ALD muscle spindle index was the highest yet published for chicken muscle and was 2.3 times higher than that of its fast counterpart. A bimodal trend in intrafusal fibre diameter was noted in the ALD, and a trimodal trend was found in the PLD. The former had 42% fewer intrafusal fibres than the latter. Muscle spindles were shorter in the ALD, with an average length of 1.9mm compared with 2.3mm in the PLD. An interesting feature of the slow muscle was the monofibril muscle spindle, containing a single intrafusal fibre. With a few exceptions, ALD muscle spindles were located within the interfascicular perimysium close to a neurovascular trunk. PLD muscle spindles were rarely seen in these areas but were frequently found within a muscle fascicle, surrounded by closely apposed extrafusal fibres. Moreover, neurovascular trunks were less frequently seen in the PLD. As an adjunct to this study, three ALD-PLD pairs from the Storrs Connecticut strain of muscular dystrophic chickens were also examined to compare muscle spindles in these muscles with those of normal animals. In the PLD, which is known to exhibit early and progressive pathological change, muscle spindles appeared relatively normal until marked extrafusal fibre degeneration had occured. By this time evidence of muscle spindle involvement included capsular hypertrophy and intrafusal fibre splitting. Whereas the slow ALD has been reported to retain apparent normalcy in muscular dystrophy, subtle changes were seen in some of the muscle spindles examined. These included an increase in number of intrafusal fibres per muscle spindle compared with those in the normal.

description: Pitch variability in rap vocals is overlooked in favor of the genre's uniquely dynamic rhythmic properties. We present an analysis of fundamental frequency (F0) variation in rap vocals over the past 14 years, focusing on song examples that represent the state of modern rap music. Our analysis aims at identifying meaningful trends over time, and is in turn a continuation of the 2023 analysis by Georgieva, Ripolles & McFee. They found rap to be an outlier with larger F0 variation compared to other genres, but with a declining trend since the genre's inception. However, they only analyzed data through 2010. Our analysis looks beyond 2010. We once again observe rap's large F0 variation, but with a decelerated decline in recent years.

description: The physical and chemical properties of the circumgalactic medium (CGM) at $z\gtrsim6$ have been studied successfully through the absorption in the spectra of background Quasi-Stellar Objects (QSOs). One of the most crucial questions is to investigate the nature and location of the source galaxies that give rise to these early metal absorbers. Theoretical models suggest that momentum-driven outflows from typical star-forming galaxies can eject metals into the CGM and the intergalactic medium (IGM) at z=5-6. Deep, dedicated surveys have searched for Ly$α$ emission associated with strong CIV absorbers at $z\approx 6$, but only a few Ly$α$ emitter candidates have been detected. Interpreting these detections is moreover ambiguous because Ly$α$ is a resonant line, raising the need for complementary techniques for detecting absorbers' host galaxies. Here, using Atacama Large Millimeter Array (ALMA), we report a [C II] 158$μ$m emitter associated with a strong low-ionization absorber, OI, at $z=5.978$. The projected impact parameter between OI and [C II] emitter is 20.0 kpc. The measured [C II] luminosity is $7.0\times 10^7$ solar luminosities. Further analysis indicates that strong OI absorbers may reside in the circumgalactic medium of massive halos one to two orders of magnitude more massive than expected values.

Slides for Webinar: Open Source and Open Standards for Digital Twins
Our new digital live will more and more gravitate around Context information describing what is happening, when, where and why. Managing this information in a Digital Twin will provide us with capabilities to improve the quality of life of people living in cities or regions. At the same time, it will be possible to reduce the cost of operating a city. But today this data and Context Information are very often organized in silos without the chance to use them for other smart solutions. Open standards for APIs and data models have the capability to break down these silos. In combination with Open Source such approaches have the potential to also reduce the ‘vendor-lock-in effect’ and to provide the lowest cost of ownership to the end user. All of this needs to be operated based on a trusted environment. GAIA-X will provide this Data Sovereignty on all levels for a trustful management of Digital Twin data.

description: The feedback from young stars (i.e. pre-supernova) is thought to play a crucial role in molecular cloud destruction. In this paper, we assess the feedback mechanisms acting within a sample of 5810 HII regions identified from the PHANGS-MUSE survey of 19 nearby ($ 1$, and expanding, yet there is a small sample of compact HII regions with $P_\mathrm{tot,max}/P_\mathrm{de} < 1$ ($\sim$1% of the sample). These mostly reside in galaxy centres ($R_\mathrm{gal}<1$kpc), or, specifically, environments of high gas surface density; log($Σ_\mathrm{gas}/\mathrm{M_\odot} \mathrm{pc}^{-2}$)$\sim$2.5 (measured on kpc-scales). Lastly, we compare to a sample of literature measurements for $P_\mathrm{therm}$ and $P_\mathrm{rad}$ to investigate how dominant pressure term transitions over around 5dex in spatial dynamic range and 10 dex in pressure.

Connectivity based parcellation and brain atlas generation - extracting connectome information for Schizophrenia research

subject: connectome
subject: Diffusion weighted image
subject: multi-class Hopfield network
subject: parcellation

description: Traditional brain atlases are mainly based on hand-crafted anatomical structures, ignoring the useful connectivity pattern information. In our work we use diffusion weighted imaging data to incorporate connectivity information into atlas generation. We use FSL to process the data to extract the connectivity matrix. The brain parcellation problem is then formulated as a min-cut problem on a big, sparse graph. Spectral clustering and an original multi-class Hopfield network (MHN) method is applied to solve the problem, each working with a different analytical framework: MHN works in the diffusion space to generate individual parcellations, while spectral clustering works on standard space averaged connectome to generate group level atlases. Group study of brain images with Schizophrenia is conducted, showing significant improvement in accuracy for disease diagnosis using features extracted with the proposed parcellation scheme. Hypothesis test was performed on local structures to explore possible structural causes of the disease.

description: The shock breakout emission is the first light that emerges from a supernova. In the spherical case it is characterized by a brief UV flash. In an axisymmetric, non-spherical prolate explosion, the shock first breaches the surface along the symmetry axis, then peels around to larger angles, producing a breakout light curve which may differ substantially from the spherically symmetric case. We study the emergence of a non-relativistic, bipolar shock from a spherical star, and estimate the basic properties of the associated bolometric shock breakout signal. We identify four possible classes of breakout light curves, depending on the degree of asphericity. Compared to spherical breakouts, we find that the main distinguishing features of significantly aspherical breakouts are 1) a longer and fainter initial breakout flash and 2) an extended phase of slowly-declining, or even rising, emission which is produced as ejecta flung out by the oblique breakout expand and cool. We find that the breakout flash has a maximum duration of roughly $\sim R_*/v_{\rm bo}$ where $R_*$ is the stellar radius and $v_{\rm bo}$ is the velocity of the fastest-moving ejecta. For a standard Wolf--Rayet progenitor, the duration of the X-ray flash seen in SN 2008D exceeds this limit, and the same holds true for the prompt X-ray emission of low-luminosity GRBs such as GRB 060218. This suggests that these events cannot be explained by an aspherical explosion within a typical Wolf--Rayet star, implying that they originate from non-standard progenitors with larger breakout radii.

description: We investigate the trapping problem in Erdos-Renyi (ER) and Scale-Free (SF) networks. We calculate the evolution of the particle density $ρ(t)$ of random walkers in the presence of one or multiple traps with concentration $c$. We show using theory and simulations that in ER networks, while for short times $ρ(t) \propto \exp(-Act)$, for longer times $ρ(t)$ exhibits a more complex behavior, with explicit dependence on both the number of traps and the size of the network. In SF networks we reveal the significant impact of the trap's location: $ρ(t)$ is drastically different when a trap is placed on a random node compared to the case of the trap being on the node with the maximum connectivity. For the latter case we find $ρ(t)\propto\exp\left[-At/N^\frac{γ-2}{γ-1}\av{k}\right]$ for all $γ>2$, where $γ$ is the exponent of the degree distribution $P(k)\propto k^{-γ}$.

Intrinsic and extrinsic drivers of spatio-temporal dynamics in Lepidoptera, and their implications for forecasting for better management strategies.
Creators: name: Gomez, Irene

description: Mobility is inherent to all organisms and serves as a mechanism for
 finding resources, mates, or better environmental conditions. Winged
 insects, in particular Lepidoptera, tend to have higher mobility than
 other insects partly due to their morphology, and their diversity.
 However, there are many factors (intraspecific, interspecific, and
 abiotic) that can affect their ability to disperse or migrate and
 determine their spatio-temporal movement patterns. Identifying these
 factors and patterns can help improve prediction and forecasting,
 especially because climate change, habitat fragmentation and anthropogenic
 dispersal can alter the distribution and dispersal of these species. In
 the second chapter of this thesis, intraspecific factors of highly mobile
 lepidoptera are explored, and findings confirm there are morphological
 differences between not only sedentary and highly mobile species, but also
 between species with different mobility behaviours like dispersal and
 migration, all linked to phylogeny. In chapters 3, 4, and 5, the African
 armyworm (AAW), a highly mobile maize pest, is used as a case study to
 explore how different abiotic factors influence its mobility and determine
 its spatio-temporal dynamics in Tanzania, in order to refine outbreak
 prediction and management strategies. Findings confirm a non-linear
 relationship between AAW migratory behaviour, and rainfall and wind, and
 also distinguish differences during the seasonal patterns (Chapter 3).
 Long-term trends indicate that the decline in AAW outbreaks in recent
 decades is related to periods of droughts and a decline of yearly
 precipitation in Tanzania, which could potentially shift the geographic
 range of the species (Chapter 4). Finally, in Chapter 5, local (Kenya and
 Tanzania) and global potential environmental suitability models are
 projected, suggesting areas where the AAW could persist if ever they were
 introduced there. Additionally, I present three potential future
 environmental suitability scenarios that are projected for Kenya and
 Tanzania, which could serve as models for setting preventive measures in
 areas of concern.

description: We present a new method to directly map the neutral-hydrogen distribution during the reionization epoch and to constrain the emission properties of the highest-redshift quasars (QSOs). As a tracer of HI, we propose to use the Ly-alpha radiation produced by quasar ionization fronts (I-fronts) that expand in the partially ionized intergalactic medium (IGM) before reionization is complete. These Ly-alpha photons are mainly generated by collisional excitations of hydrogen atoms in the boundary of the rapidly expanding HII region. The observable signal is produced by the part of the I-front that lies behind the QSO with respect to the observer. Combining two radiative transfer models (one for the QSO ionizing radiation and one for the Ly-alpha photons), we estimate the expected Ly-alpha spectral shape and surface brightness (SB) for a large number of configurations where we varied both the properties of the ionizing QSO and of the surrounding medium. We find that the expected signal is observable as a single (broad) emission line with a characteristic width of 100-200 km/s. The expected SB produced at redshift z~6.5 within a fully neutral region (at mean density) by a typical QSO I-front lies in the range $10^{-21}-10^{-20}$ erg s$^{-1}$ cm$^{-2}$ arcsec$^{-2}$ and decreases proportionally to $(1+z)^2$ for a given QSO age. QSOs with harder spectra may produce a significantly brighter emission at early phases. The signal may cover up to a few hundred square arcmin on the sky and should be already detectable with current facilities by means of moderate/high resolution spectroscopy. The detection of this Ly-alpha emission can shed new light on the reionization history, the age and the emission properties of the highest-redshift QSOs. (abridged)

description: Even within the framework of the leading logarithmic approximation the eigenvalues of the BKP kernel for states of more than three reggeized gluons are unknown in general, contrary to the planar limit case where the problem becomes integrable. We consider a 4-gluon kernel for a finite number of colors and define some simple toy models for the configuration space dynamics, which are directly solvable with group theoretical methods. Then we study the dependence of the spectrum of these models with respect to the number of colors and make comparisons with the large limit case.

A New N=4 Membrane Action via Orbifold

description: We propose a new Lagrangian describing N=4 superconformal field theory in three dimensions. This theory is believed to describe interacting field theory on the worldvolume of a M2-brane on an orbifold, and is obtained as a Z_2-quotient of the theory proposed by Bagger and Lambert. Despite unusual Chan-Paton structures, we can take Z_2-orbifold by using SU(2)\times SU(2) bifundamental representations. We also analyze the moduli space of this theory and found three branches. With an assumption of a broken U(1) symmetry, the moduli space is consistent with that of the D2-brane in the strong coupling limit of Type IIA string theory if the gauge group is O(4). Our action has manifest Z_2-symmetry exchanging two R^4/Z_2's in M-theory, and this suggests a new non-perturbative duality between a O2^{-}-brane on orbifold R^4/Z_2 and a O2^{-}-brane with D6-branes.

Long-Lived Highly Emissive MOFs as Potential Candidates for Multiphotonic Applications

description: Long-lived emissive materials based on room temperature phosphorescence (RTP) and thermally activated delayed fluorescence (TADF) are considered as the cornerstone of the development of optical sensors, security systems and solid-state lighting. Nevertheless, molecular systems with these properties are scarce because most of them suffer from aggregation caused quenching emission (ACQ). One approach to address this shortcoming is by inhibiting the molecular motions/vibrations by employing a fixed matrix as afforded by a metal-organic framework (MOF). There, the organic chromophores are confined in a crystalline framework, and the structure-property relationship can be designed to get RTP/TADF. Inspired by this, the present work explores the relation between the linker arrangement and the physicochemical properties of two isochemical MOFs with different crystalline structures. The denser MOF exhibits a long-lived green RTP due to a hyperfine coupling of the linkers. On the other hand, the more porous MOF presents a long-lived temperature-dependent turquoise emission, reflecting the influence of the TADF. Hence, this study provides a huge advance about the potential of MOFs to undergo RTP and TADF emission, and at the same time, demonstrates their potential applicability in a wide range of photonic technologies, including physical and chemical sensing and the first example of a MOF-LED based on RTP-MOFs.

The Properties of Long-Period Variables in the Large Magellanic Cloud from MACHO

description: We present a new analysis of the long-period variables in the Large Magellanic Cloud (LMC) from the MACHO Variable Star Catalog. Three-quarters of our sample of evolved, variable stars have periodic light curves. We characterize the stars in our sample using the multiple periods found in their frequency spectra. Additionally, we use single-epoch Two Micron All Sky Survey measurements to construct the average infrared light curves for different groups of these stars. Comparison with evolutionary models shows that stars on the red giant branch (RGB) or the early asymptotic giant branch (AGB) often show non-periodic variability, but begin to pulsate with periods on the two shortest period-luminosity sequences (3 & 4) when they brighten to K_s ~ 13. The stars on the thermally pulsing AGB are more likely to pulsate with longer periods that lie on the next two P-L sequences (1 & 2), including the sequence associated with the Miras in the LMC. The Petersen diagram and its variants show that multi-periodic stars on each pair of these sequences (3 & 4, and 1 & 2) typically pulsate with periods associated only with that pair. The periods in these multi-periodic stars become longer and stronger as the star evolves. We further constrain the mechanism behind the long secondary periods (LSPs) seen in half of our sample, and find that there is a close match between the luminosity functions of the LSP stars and all of the stars in our sample, and that these star's pulsation amplitudes are relatively wavelength independent. Although this is characteristic of stellar multiplicity, the large number of these variables is problematic for that explanation.

description: The boundary correlation functions for a Quantum Field Theory (QFT) in an Anti-de Sitter (AdS) background can stay conformally covariant even if the bulk theory undergoes a renormalization group (RG) flow. Studying such correlation functions with the numerical conformal bootstrap leads to non-perturbative constraints that must hold along the entire flow. In this paper we carry out this analysis for the sine-Gordon RG flows in AdS$_2$, which start with a free (compact) scalar in the UV and end with well-known massive integrable theories that saturate many S-matrix bootstrap bounds. We numerically analyze the correlation functions of both breathers and kinks and provide a detailed comparison with perturbation theory near the UV fixed point. Our bounds are often saturated to one or two orders in perturbation theory, as well as in the flat-space limit, but not necessarily in between.

Optimised Time for Travelling Wave Fault Locators in the Presence of Different Disturbances Based on Real-World Fault Data
Creators: Mahmood Parsi and Peter A. Crossley
Publisher: name: IEEE
Year: 2021

The real-world travelling wave fault data investigated in this paper indicate disturbances generate unpredictable, non-stationary and random waveforms which may cause maloperation of protection and control elements in a power system including travelling wave fault locators.
The real-world travelling wave fault data investigated in this paper indicate disturbances generate unpredictable, non-stationary and random waveforms which may cause maloperation of protection and control elements in a power system including travelling wave fault locators (TWFL). This type of fault locator is directly dependent on the detection of an accurate time of arrival (ToA) of travelling waves (TW) generated by a fault. This detection becomes complicated in the presence of disturbances when their ToAs are detected earlier than the fault TWs. Since travelling waves occur in the high-frequency bands (e.g. >50 kHz), in this paper a capacitor voltage transformer is employed to measure the TW voltage signals; this involves acquiring the current flowing to the ground and removing the low-frequency components (50/60 Hz). Disturbances create high magnitude pulses in the pre-fault section of a TW fault signal that last for a short time. Therefore, the time when a TWFL starts its computations requires to be optimised so that the effect of the disturbances is eliminated. The analysis techniques mentioned in this paper are based on real-world travelling wave fault data, and the solution uses statistical tools, such as cost function, mean and standard deviation, alongside Digital Signal Processing algorithms.
