description: Within the open science and research data communities, digital preservation has a close alignment to the FAIR principles and is delivered through a complex specialist infrastructure comprising technology, staff and policy. Capacity erodes quickly, establishing a need for ongoing examination and review to ensure that skills, technology, and policy remain fit for changing purpose. This presentation draws from the DPC 'FAIR Forever' study, commissioned by the EOSC Sustainability Working Group and funded by the EOSC Secretariat Project in 2020, to highlight the study's key findings on the need for clarity on digital preservation in the EOSC vision and for elucidation of roles, responsibilities, and accountabilities to mitigate risks of data loss, reputation, and sustainability. The nineteen recommendations of the study are presented with discussion on how they might be extended and applied to various research data stakeholders in and outside of EOSC, and ways to bring together research data curation, management, and preservation communities to better ensure FAIRness now and in the long term.

description: We revisit the orbital history of the Triangulum galaxy (M33) around the Andromeda galaxy (M31) in view of the recent Gaia Data Release 2 proper motion measurements for both Local Group galaxies. Earlier studies consider highly idealised dynamical friction, but neglect the effects of dynamical mass loss. We show the latter process to be important using mutually consistent orbit integration and N-body simulations. Following this approach we find an orbital solution that brings these galaxies to within ~50 kpc of each other in the past, ~6.5 Gyr ago. We explore the implications of their interaction using an N-body/hydrodynamical simulation with a focus on the origin of two prominent features: 1) M31's Giant Stellar Stream; and 2) the M31-M33 HI filament. We find that the tidal interaction does not produce a structure reminiscent of the stellar stream that survives up to the present day. In contrast, the M31-M33 HI filament is likely a fossil structure dating back to the time of the ancient encounter between these galaxies. Similarly, the observed outer disc warp in M33 may well be a relic of this past event. Our model suggests the presence of a tidally induced gas envelope around these galaxies, and the existence of a diffuse gas stream, the 'Triangulum stream', stretching for tens of kpc from M33 away from M31. We anticipate upcoming observations with the recently commissioned, Five-hundred-meter Aperture Spherical radio Telescope (FAST) that will target the putative stream in its first years of operation.

 Aplidium robustum Kott 1992a, p 582.
 Distribution
Previously recorded (Kott 1992a): Western Australia (King George Sound); South Australia (Great Australian Bight); Tasmania (Dunalley). New records: Tasmania (Bass Strait, 70 m, QM G308806–7).
 Remarks
 The newly recorded colonies are identical with those previously assigned to the species, being soft, irregular, fleshy masses with sand embedded only in the base. The crowded zooids, their long, narrow thoraces, orange in preservative and with about 20 longitudinal folds in the small stomach, are arranged in circular systems. The soft test contains white, opaque corpuscles in the layer that closely surrounds the zooids. The newly recorded zooids have the atrial tongue separate from the aperture, although this has not previously been reported for this species. The species resembles A. multiplicatum Sluiter, 1909 although the larvae and the cloacal systems are different (see Kott 1992a).

description: We study the elastic properties of a single A/B copolymer chain with a specific sequence. We predict a rich structure in the force extension relations which can be addressed to the sequence. The variational method is introduced to probe local minima on the path of stretching and releasing. At given force, we find multiple configurations which are separated by energy barriers. A collapsed globular configuration consists of several domains which unravel cooperatively. Upon stretching, unfolding path shows stepwise pattern corresponding to the unfolding of each domain. While releasing, several cores can be created simultaneously in the middle of the chain resulting in a different path of collapse.

(Figure 7A–D)
 Distribution
 Type locality. Tasmania (Bellerive Bluff, Derwent River estuary, 6 m low reef, coll. Aquenal L. K. Lyell, R. B. Mawby, and K. O. Redburn, holotype QM G308839; paratype QM G308828).
 Description
In life, the specimens are more or less ovoid, to about 4 cm long, with a terminal branchial aperture and sessile atrial aperture one-third to half of the body length along the dorsum. In preservative they are dorso-ventrally flattened. The test is firm and translucent with seven lobes around the branchial aperture and six around the almost sessile atrial aperture. Small, pointed papillae are on the outside of these lobes. About 20 branchial tentacles are well separated from one another in a single circle at the base of the branchial siphon. The prebranchial area is narrow and a large dorsal tubercle with a U-shaped slit fills a shallow peritubercular V at the anterior end of the ribbed dorsal lamina, which is a double membrane in its anterior half. The horns of the slit on the dorsal tubercle are both rolled inwards. The dorsal ganglion is beneath and slightly behind the dorsal tubercle. About four stigmata are in each mesh and papillae are at the junctions of the internal longitudinal branchial vessels and the transverse vessels. The gut forms a double loop. The descending limb forming the inner curve of the secondary loop is filled with an accumulation of mud. Gonads are obscured by the mud-filled gut.
 Remarks
 The species has much in common with others that accumulate mud in the gut, namely A. challengeri, A. sydneyensis, and A. thompsoni (Table IV). These species all have a translucent test, and all except A. sydneyensis have a mesh of muscles on the right side of the body and a relatively simple U-shaped slit on the dorsal tubercle. All except A. thompsoni have the dorsal ganglion close to the dorsal tubercle and lack a postero-dorsal bend of the distal part of the rectum. Ascidia thompsoni also has more branchial tentacles (about 100) than the present species. The species most closely related to the present one is the Antarctic A. challengeri which is distinguished only by its more numerous stigmata in each mesh and the arrangement of the branchial tentacles, which are in two circles in the prebranchial area and connected to an oral flange at the base of the branchial siphon by a thin vertical ridge in the pharyngeal lining.
The present specimens have small black spherical bodies in the body wall although they seem not to be related to the colour of living specimens.

description: The phase diagram of a polydisperse mixture of uniaxial rod-like and plate-like hard parallelepipeds is determined for aspect ratios $κ=5$ and 15. All particles have equal volume and polydispersity is introduced in a highly symmetric way. The corresponding binary mixture is known to have a biaxial phase for $κ=15$, but to be unstable against demixing into two uniaxial nematics for $κ=5$. We find that the phase diagram for $κ=15$ is qualitatively similar to that of the binary mixture, regardless the amount of polydispersity, while for $κ=5$ a sufficient amount of polydispersity stabilizes the biaxial phase. This provides some clues for the design of an experiment in which this long searched biaxial phase could be observed.

Global Dynamics in the Singular Logarithmic Potential

description: We present an analytical description of the motion in the singular logarithmic potential. This potential plays an important role in the modeling of triaxial systems (like elliptical galaxies) or bars in the centers of galaxy disks. In order to obtain information about the motion near the singularity, we resort to McGehee -type transformations and regularize the vector field. In the axis-symmetric case (b=1), we offer a complete description of the global dynamics. In the non axis-symmetric case (b<1), we prove that all orbits, with the exception of a negligible set, are centrophobic and retrieve numerically partial aspects of the orbital structure.

description: We construct a scotogenic neutrino mass model introducing large $SU(2)_L$ multiplet fields without adding an extra symmetry. We have introduced extra scalar fields such as a septet, quintet and quartet where we make the vacuum expectation value of quartet scalar to be zero while septet and quintet develop non-zero ones. Then the neutrino mass is generated at one-loop level by introducing quintet fermion. We analyze the neutrino mass matrix taking constraints from lepton flavor violation into account and discuss collider physics regarding charged fermions from large multiplet fields. We have analysed the production and the decays of the quintet fermions, as well as the discovery reach at 14 TeV and 27 TeV LHC.

description: We calculate the collective excitations in a homogeneous F=2 spinor condensate in the absence of the magnetic field and also in a strong magnetic field. Almost all the excitations for a zero magnetic field are found to have either the Bogoliubov form or the free-particle form. We relate our results for a strong magnetic field to the concept of fragmented condensates and note that some observable quantities such as the speed of sound for the cyclic state depend on the relative phase between the spinor amplitudes for the $M=\pm 2, 0$ atoms.

description: Many scientific applications require the solution of large initial-value problems, such as those produced by the method of lines after semi-discretization in space of partial differential equations. The computational cost of implicit time discretizations is dominated by the solution of nonlinear systems of equations at each time step. In order to decrease this cost, the recently developed Rosenbrock-Krylov (ROK) time integration methods extend the classical linearly-implicit Rosenbrock(-W) methods, and make use of a Krylov subspace approximation to the Jacobian computed via an Arnoldi process. Since the ROK order conditions rely on the construction of a single Krylov space, no restarting of the Arnoldi process is allowed, and the iterations quickly become expensive with increasing subspace dimensions. This work extends the ROK framework to make use of the Lanczos biorthogonalization procedure for constructing Jacobian approximations. The resulting new family of methods is named biorthogonal ROK (BOROK). The Lanczos procedure's short two-term recurrence allows BOROK methods to utilize larger subspaces for the Jacobian approximation, resulting in increased numerical stability of the time integration at a reduced computational cost. Adaptive subspace size selection and basis extension procedures are also developed for the new schemes. Numerical experiments show that for stiff problems, where a large subspace used to approximate the Jacobian is required for stability, the BOROK methods outperform the original ROK methods.

 Abstract
Asenapine, an atypical antipsychotic indicated for the treatment of schizophrenia, was first available as a twice-daily sublingual tablet. However, there are some challenges associated with the use of sublingual asenapine. More recently, a comparable transdermal formulation of asenapine (Secuado®) has been approved in the USA as the first antipsychotic patch for the treatment of schizophrenia in adults. Asenapine transdermal delivery system (TDS) offers a simpler and more convenient dosage regimen and avoids adverse events related to sublingual administration, potentially leading to better adherence to treatment. In a pivotal 6-week phase 3 study in patients with an acute exacerbation of schizophrenia, once-daily application of asenapine TDS 3.8 mg/24 h and 7.6 mg/24 h significantly reduced psychotic symptoms and global disease severity compared with placebo. Asenapine TDS is generally well tolerated, with the systemic safety profile being largely consistent with that established for sublingual asenapine. Although the use of asenapine TDS is associated with application site reactions, these reactions are generally mild to moderate in severity.

description: Electrical conduction is studied along parabolically confined quasi-one dimensional channels, in the framework of a revised linear-response theory, for elastic scattering. For zero magnetic field an explicit multichannel expression for the conductance is obtained that agrees with those of the literature. A similar but new multichannel expression is obtained in the presence of a magnetic field B||z perpendicular to the channel along the x axis. An explicit connection is made between the characteristic time for the tunnel-scattering process and the transmission and reflection coefficients that appear in either expression. As expected, for uncoupled channels the finite field expression gives the complete (Landauer-type) conductance of N parallel channels, a result that has not yet been reported in the literature. In addition, it accounts explicitly for the Hall field and the confining potential and is valid, with slight modifications, for tilted magnetic fields in the (x,z) plane.

description: In 2010, the European (EU) High Level Expert Group on milk proposed the introduction of standard contracts between raw milk producers and processors to improve the bargaining position of producers and to stabilize the market by balancing dairy supply and demand. However, contracts may distort competition and deter market entry of rival dairies. We analyze competitive effects of contracts between dairy producers and processors by constructing a game theoretic model. We show that an incumbent dairy can deter a rival dairy’s market entry by offering an exclusive contract to a risk averse producer.

 Distribution
 Type locality. Tasmanian Canyons (38.11482 ° S, 149.3565 ° E, Banks Strait, 168 m, 25 April 2004, Sherman sled, species 10, syntypes two QM G308832; King I. Canyon, 294 m; Pieman Canyon, 176 m; Big Horseshoe, 159 m).
 Description
Colonies are sessile globes or cones or stumpy upright lobes, fixed to the substratum by a sandy hold-fast in the centre of the lower surface. The test in all the recorded specimens is soft and almost liquid and the arrangement of the zooids was not determined.
In most of the specimens, the zooids are in vegetative phase, with small, juvenile regenerating thorax and abdomen on a long posterior abdomina. Details of the zooid structure could be determined in only a few zooids in the syntype colonies. The zooids are long and thin as in many species in this genus. The atrial tongue arises from the anterior rim of the aperture and the thorax is long and narrow with 18 rows of about 20 stigmata. The abdomen is relatively short with five gastric folds and the posterior abdomen is long and narrow.
 Remarks
 The almost liquid test of this species is reminiscent of the test of Pseudodistoma fragilis Tokioka, 1958 (from Japan) and P. gracile Kott, 1992a from the tropical Western Pacific (see Kott 1992a). However, the zooids in the syntype material are characteristic of the genus Aplidium. Although known species often have zooids and even colonies that generally resemble those of the present species, an Aplidium species with its very soft test has not been encountered and the species is not readily assigned to any known Australasian or sub-Antarctic species.

We show that this complex reduces to a coherent sheaf F exactly when the Alexander dual Delta^* is Cohen-Macaulay. We then determine when both Delta and Delta^* are Cohen-Macaulay. This corresponds to F being a locally Cohen-Macaulay sheaf. Lastly we conjecture for which range of invariants of such Delta it must be a cone.

description: The Poisson multi-Bernoulli mixture (PMBM) and the multi-Bernoulli mixture (MBM) are two multi-target distributions for which closed-form filtering recursions exist. The PMBM has a Poisson birth process, whereas the MBM has a multi-Bernoulli birth process. This paper considers a recently developed formulation of the multi-target tracking problem using a random finite set of trajectories, through which the track continuity is explicitly established. A multi-scan trajectory PMBM filter and a multi-scan trajectory MBM filter, with the ability to correct past data association decisions to improve current decisions, are presented. In addition, a multi-scan trajectory $\text{MBM}_{01}$ filter, in which the existence probabilities of all Bernoulli components are either 0 or 1, is presented. This paper proposes an efficient implementation that performs track-oriented $N$-scan pruning to limit computational complexity, and uses dual decomposition to solve the involved multi-frame assignment problem. The performance of the presented multi-target trackers, applied with an efficient fixed-lag smoothing method, are evaluated in a simulation study.

description: [Abridged] We present here a new and homogeneous sample of 3340 galaxies selected from the Sloan Digital Sky Survey (SDSS) based solely on the observed strength of their Hdelta absorption line. These galaxies are commonly known as ``post-starburst'' or ``E+A'' galaxies, and the study of these galaxies has been severely hampered by the lack of a large, statistical sample of such galaxies. In this paper, we rectify this problem by selecting a sample of galaxies which possess an absorption Hdelta equivalent width of EW(Hdelta_max) - Delta EW(Hdelta_max) > 4A from 106682 galaxies in the SDSS. We have performed extensive tests on our catalog including comparing different methodologies of measuring the Hdelta absorption and studying the effects of stellar absorption, dust extinction, emission-filling and measurement error. The measured abundance of our Hdelta-selected (HDS) galaxies is 2.6 +/- 0.1% of all galaxies within a volume-limited sample of 0.05

description: Grassland ecological protection measures such as grazing prohibition and livestock changed traditional production mode of the cashmere goat industry, and exerted adverse influence on production of cashmere and income of farmers and herdsmen. On the basis of the survey in Inner Mongolia, Xinjiang, Jilin, Liaoning, Shanxi, and Yunnan, this paper evaluated effect of subsidy policies on cashmere goat industry and present some existing problems in the implementation of these policies. Finally, it came up with following recommendations: strengthening cultivation and protection of cashmere goat varieties, increasing subsidy level of fine varieties and expanding coverage of subsidy policies, formulating cashmere price supportive measures, enhancing construction of cashmere goat sci-tech service system, and promoted standardized production of cashmere goat.

description: Bio-assays were conducted to investigate the mating behavior and associated vibrational signals of the Xylella fastidiosa vector, Philaenus spumarius. After characterization of vibrations involved in pair formation, studies were conducted to assess whether female receptivity to mating is correlated to ovarian development. It was observed that females emitted mating signals from the end of the summer onward, and that signaling activity and responsiveness to mating were correlated with ovarian development. In addition, to evaluate whether a vibrational stimulus could disrupt mating, pairs were treated with a continuous broad-band noise with a frequency range of 150-1200 Hz. Although both females and males emitted mating signals during the treatment, the noise could disrupt the pair formation process, likely by preventing mate finding. Further research on larger scale should be conducted to develop future control mating disruption techniques, which should be applied at the end of the summer, when both sexes are sexually mature.

description: We calculate, as a function of temperature and conduction band electron density, the optical absorption of a weakly n-doped, idealized semiconductor quantum well. In particular, we focus on the absorption band due to the formation of a charged exciton. We conceptualize the charged exciton as an itinerant excitation intimately linked to the dynamical response of itinerant conduction band electrons to the appearance of the photo-generated valence band hole. Numerical results for the absorption in the vicinity of the exciton line are presented and the spectral weights associated with, respectively, the charged exciton band and the exciton line are analyzed in detail. We find, in qualitative agreement with experimental data, that the spectral weight of the charged exciton grows with increasing conduction band electron density and/or decreasing temperature at the expense of the exciton.

description: In this paper we report on $\sim10$ years of observations of PSR J2051$-$0827, at radio frequencies in the range 110--4032 MHz. We investigate the eclipse phenomena of this black widow pulsar using model fits of increased dispersion and scattering of the pulsed radio emission as it traverses the eclipse medium. These model fits reveal variability in dispersion features on timescales as short as the orbital period, and previously unknown trends on timescales of months--years. No clear patterns are found between the low-frequency eclipse widths, orbital period variations and trends in the intra-binary material density. Using polarisation calibrated observations we present the first available limits on the strength of magnetic fields within the eclipse region of this system; the average line of sight field is constrained to be $10^{-4}$ G $\lesssim B_{||} \lesssim 10^2$ G, while for the case of a field directed near-perpendicular to the line of sight we find $B_{\perp} \lesssim 0.3$ G. Depolarisation of the linearly polarised pulses during the eclipse is detected and attributed to rapid rotation measure fluctuations of $σ_{\text{RM}} \gtrsim 100$ rad m$^{-2}$ along, or across, the line of sights averaged over during a sub-integration. The results are considered in the context of eclipse mechanisms, and we find scattering and/or cyclotron absorption provide the most promising explanation, while dispersion smearing is conclusively ruled out. Finally, we estimate the mass loss rate from the companion to be $\dot{M}_{\text{C}} \sim 10^{-12} M_\odot$ yr$^{-1}$, suggesting that the companion will not be fully evaporated on any reasonable timescale.

(Figure 10G)
 Styelopsis scaevola Sluiter 1904, p 89.
 Ascidia scaevola: Kott 1985, p 53 and synonymy.
 Distribution
 Previously recorded (see Kott 1985): South Australia (Great Australian Bight, St Vincent Gulf); Victoria (Lakes Entrance, Sale, Port Phillip Bay); Queensland (Moreton Bay, Gladstone, Bowen Townsville, Nymph I.); Indonesia. New records: South Australia (Edithburgh, 3–4 m, SAM E2871); Tasmanian Canyons (40.79269 ° S, 144.21916 ° E, 94 m).
 Description
The specimens are up to 14 cm long. As usual, they are dorso-ventrally flattened with the body wall closely adherent to the stiff, brittle, thin, sandy test. The sessile branchial and atrial openings, respectively, are at the base of the incurrent and excurrent pseudosiphons, which rise vertically from the upper surface. In the largest specimen the outer half of each tube is bent in the same direction. Internally the thin body wall, branchial wall, short transverse muscle bands, large branchial fold and flat, double gut loop are as previously described (Kott 1985).
 Remarks
 The collector has noted that the Edithburgh specimens are buried in sand, only the pseudosiphons projecting above the sea floor. The pseudosiphons of the present species are distinctive, as are the short muscle bands. But in some respects the species resembles Phallusia polytrema (Herdman, 1906) and Microgastra granosa (see below) and they all appear to occupy sea-floor habitats where they are buried in sand. They all have thin, brittle sand-filled test, a thin body wall adhering closely to the test and delicate branchial sacs. However, in the former species, the descending limb of the gut loop accumulates sand and the gut forms a simple J-shaped loop; while in the latter species (which has a dorsal branchial fold like A. scaevola), the small gut loop is evaginated from the body wall and the distinctive gonads and neural organs with their associated part of the body wall, are embedded in the test.

description: The resting full-cycle ratio (RFR), a new non-congestive resting index, is commonly used for physiological evaluations of coronary arteries. This study aims to evaluate the accuracy of RFR in detecting coronary artery stenosis with hemodynamic significance using fractional flow reserve (FFR) as the reference standard. Using ‘RFR, resting full-cycle ratio’ as the search term, we searched PubMed, Embase, Cochrane Library, and Web of Science databases, screening the literature according to the inclusion and exclusion criteria. By applying FFR ≤ 0.80 and RFR ≤ 0.89 as the diagnostic criteria for ischaemia, we analysed the synthetic sensitivity, specificity, and corresponding 95% confidence intervals, then synthesised the summary receiver operating characteristic curve (SROC). Three studies were included in this meta-analysis, comprising 1,084 patients with 1,312 lesions. When we used FFR ≤ 0.80 as the reference standard, the synthesised sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) of RFR in the diagnosis of coronary ischaemia were 73%, 81%, 67%, 85%, 3.95, and 0.33, respectively. Besides, the area under the curve (AUC) was 0.8276. Using FFR as the reference standard, RFR has good diagnostic accuracy in detecting coronary ischaemic lesions and may be an effective alternative to FFR in the future, to some extent.

description: Financial correlation matrices measure the unsystematic correlations between stocks. Such information is important for risk management. The correlation matrices are known to be ``noise dressed''. We develop a new and alternative method to estimate this noise. To this end, we simulate certain time series and random matrices which can model financial correlations. With our approach, different correlation structures buried under this noise can be detected. Moreover, we introduce a measure for the relation between noise and correlations. Our method is based on a power mapping which efficiently suppresses the noise. Neither further data processing nor additional input is needed.

description: With the assumption of classical scale invariance at the Planck scale, the DFSZ axion model can generate the Higgs mass terms of the appropriate size through technically natural parameters and may be valid up to the Planck scale. We discuss the high scale validity of the Higgs sector, namely the absence of Landau poles and the vacuum stability. The Higgs sector is identical to that of the type-II two Higgs doublet model with a limited number of the Higgs quartic couplings. We utilize the state-of-the-art method to calculate vacuum decay rates and find that they are enhanced at most by 10^10 compared with the tree level evaluation. We also discuss the constraints from flavor observables, perturbative unitarity, oblique parameters and collider searches. We find that the high scale validity tightly constrains the parameter region, but there is still a chance to observe at most about 10% deviation of the $125~{\rm GeV}$ Higgs couplings to the fermions.

description: Alzheimer’s disease is a neurodegenerative disorder mainly characterized by β-amyloid deposit and tau hyperphosphorylation with no curative treatments. Curcumin (Cur) has been proved to have potential use in Alzheimer’s disease with its anti-amyloid, anti-inflammatory, and anti-oxidant properties, etc. However, its hydrophobicity and low bioavailability hinder its application. In this paper, we designed a novel brain-target nanoparticle, poly(lactide-co-glycolide)-block-poly(ethylene glycol) (PLGA-PEG) conjugated with B6 peptide and was loaded with Cur (PLGA-PEG-B6/Cur) and administered it into HT22 cells and APP/PS1 Al transgenic mice. The in vitro assays including dynamic light scattering (DLS), flow cytometry (FCM), red blood cell (RBC) lysis, and thromboelastography (TEG) analysis indicated that this nanoparticle could narrow the diameter of Cur, increase its cellular uptake and possess good blood compatibility. The results from Morris water maze proved that PLGA-PEG-B6/Cur could tremendously improve the spatial learning and memory capability of APP/PS1 mice, compared with native Cur. The ex vivo assays including Bielschowsky silver staining, immunostaining, and western blotting demonstrated that PLGA-PEG-B6/Cur could reduce hippocampal β-amyloid formation and deposit and tau hyperphosphorylation. Thus, we suggested that PLGA-PEG-B6/Cur nanoparticles would be of potential and promising use for the treatment of Alzheimer’s disease.
