description: A physical system is called quasi-isolated if it subject to small random uncontrollable perturbations. Such a system is, in general, stochastically unstable. Moreover, its phase-space volume at asymptotically large time expands. This can be described by considering the local expansion exponent. Several examples illustrate that the stability indices and expansion exponents of quasi-isolated systems are not only asymptotically positive but are asymptotically increasing. This means that the divergence of dynamical trajectories and the expansion of phase volume at large time occurs with acceleration. Such a strongly irreversible evolution of quasi-isolated systems explains the irreversibility of time.

 Remarks. — Flabellum apertum was first reported (Moseley 1881) from off Chile (48°S, Golfo de Penas) as F. patagonichum at 220 m. Cairns (1982) later reported two records from the continental slope off Isla Desolación (1262–1500 m). Specimens reported herein were also collected off Isla Desolación, off Islas Morton, and a northern range extension at 34°S. The species is thus known from 34° to 56°S off the Chilean coast at depths of 193–1500 m but is more widespread throughout the Subantarctic at similar depths (Cairns 1982, 1995). It is well described and illustrated by Cairns (1982, 1995).

description: Ionic liquids (ILs), also known as room-temperature molten salts, are composed of pure ions with melting points usually below 100 degrees centigrade. Because of their low volatility and vast amounts of species, ILs can serve as "green solvents" and "designer solvents" to meet the requirements of various applications by fine tuning their molecular structures. A good understanding of the phase behaviors of ILs is certainly fundamentally important in terms of their wide applications. This review intends to summarize the major conclusions so far drawn on phase behaviors of ILs by computational, theoretical, and experimental studies, illustrating the intrinsic relationship between their dual ionic and organic nature and the crystalline phases, nanoscale segregation liquid phase, ionic liquid crystal phases, as well as phase behaviors of their mixture with small organic molecules.

description: Increasing amounts of disposable food packaging waste are contributing towards a global environmental crisis, and approaches to successfully preventing such waste—called precycling—are urgently needed. The human ability to define oneself as a member of a group (social identity) may represent a powerful source for realizing environmental endeavors. Therefore, in this article we conceptualize precycling behavior in households as pro-environmental behavior embedded in social identity processes. To explore precycling, we combined food diaries and qualitative virtual interviews with 26 households in Berlin, Germany. We analyzed our data based on the Social Identity Model of Pro-Environmental Action (SIMPEA). Starting from the behavioral element of the model (response), we substantiate the concept of precycling suggesting that it can be distinguished into six types of behavior. Furthermore, we propose that the enactment of these precycling behaviors is shaped by social identity processes and social influence in different groups, including: the household itself, neighbors, family and friends, or food collectives. We conclude that these processes are important to realizing precycling in small and private groups as well as in larger collectives. Implications are derived for empirical research and theoretical development as well as for public programs and intervention studies.

description: In the observation of sky-averaged HI signal from Epoch of Reionization, model parameter inference can be a computation-intensive work, which makes it hard to perform a direct one-stage model parameter inference by using MCMC sampling method in Bayesian framework. Instead, a two-stage inference is usually used, i.e., the parameters of some characteristic points on the EoR spectrum model are first estimated, which are then used as the input to estimate physical model parameters further. However, some previous works had noticed that this kind of method could bias results, and it could be meaningful to answer the question of whether it is feasible to perform direct one-stage MCMC sampling and obtain unbiased physical model parameter estimations. In this work, we studied this problem and confirmed the feasibility. We find that unbiased estimations to physical model parameters can be obtained with a one-stage direct MCMC sampling method. We also study the influence of some factors that should be considered in practical observations to model parameter inference. We find that a very tiny amplifier gain calibration error ($10^{-5}$ relative error) with complex spectral structures can significantly bias the parameter estimation; the frequency-dependent antenna beam and geographical position can also influence the results, so that should be carefully handled.

 Remarks. —This species has been reported only by Cairns (1982) from the continental slope off Isla Desolación (type locality) and off Taltal, Chile (25°– 53°S, 950–1896 m), as well as off Peru (8°S) and the Falkland Plateau (as shallow as 595 m). It is easily recognized by having a basal scar from which it asexually detaches from an attached anthocaulus. Cairns (1989: Table 6) implied that T. truncum was a junior synonym of T. trapezoideum Keller, 1981, the latter known only from the Marcus Necker Ridge at 1630 m, but Cairns et al. (1999) listed them as separate species. Both species are poorly known and should be closely compared when more specimens are available.

description: We show with a short Chandra HRC-S exposure that the powerful X-ray source coincident with the nucleus of M33 is unresolved at the highest spatial resolution available to date (0"4). The source flux is variable, doubling during the 5 ks exposure. The combination of properties exhibited by M33 X-8 establishes the source as the nearest example of the ultra-luminous X-ray sources that have been uncovered in other nearby galaxies. On short timescales, we set limits of 9% r.m.s. variability for pulsations in the 0.01-1000 Hz range.

description: This work presents multi-scale approaches to investigate 3D printed structured Mn–Na–W/SiO2 catalysts used for the oxidative coupling of methane (OCM) reaction. The performance of the 3D printed catalysts has been compared to their conventional analogues, packed beds of pellets and powder. The physicochemical properties of the 3D printed catalysts were investigated using scanning electron microscopy, nitrogen adsorption and X-ray diffraction (XRD). Performance and durability tests of the 3D printed catalysts were conducted in the laboratory and in a miniplant under real reaction conditions. In addition, synchrotron-based X-ray diffraction computed tomography technique (XRD-CT) was employed to obtain cross sectional maps at three different positions selected within the 3D printed catalyst body during the OCM reaction. The maps revealed the evolution of catalyst active phases and silica support on spatial and temporal scales within the interiors of the 3D printed catalyst under operating conditions. These results were accompanied with SEM-EDS analysis that indicated a homogeneous distribution of the active catalyst particles across the silica support.

 Remarks. — Squires (1969) was the first to indicate this species occurring in Chile, from the Drake Passage off Cape Horn, these three records later documented by Cairns (1982) from 494–1137 m. Specimens reported herein extend the Chilean distribution farther northward to off Isla Desolación (53°S) and to a depth of 132 m. The main distribution of this species is off Venezuela Tierra del Fuego, the Falkland Islands, and South Georgia at depths of 75–780 m (Cairns 1982). It is unique among the Chilean coral fauna as being the only known dendrophylliid species. It is described and illustrated by Cairns (1982).

Kepler data analysis: non-Gaussian noise and Fourier Gaussian process analysis of star variability

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We develop a statistical analysis model of Kepler star flux data in the presence of planet transits, non-Gaussian noise, and star variability. We first develop a model for Kepler noise probability distribution in the presence of outliers, which make the noise probability distribution non-Gaussian. We develop a signal likelihood analysis based on this probability distribution, in which we model the signal as a sum of the star variability and planetary transits. We argue these components need to be modeled together if optimal signal is to be extracted from the data. For the star variability model we develop an optimal Gaussian process analysis using a Fourier based Wiener filter approach, where the power spectrum is non-parametric and learned from the data. We develop high dimensional optimization of the objective function, where we jointly optimize all the model parameters, including thousands of star variability modes, and planet transit parameters. We apply the method to Kepler-90 data and show that it gives a better match to the star variability than the standard spline method, and robustly handles noise outliers. As a consequence, the planet radii have a higher value than the standard spline method.

Obligasi Penilaian dan Hasil atau dalam bahasa Inggris dikenal sebagai "Bonds: Valuation and Yield," adalah konsep dasar dalam dunia keuangan yang berkaitan dengan bagaimana nilai obligasi dihitung serta bagaimana hasil atau return dari obligasi diukur.

Obligasi (Bonds): Obligasi adalah instrumen utang yang diterbitkan oleh pemerintah, perusahaan, atau entitas lain untuk mengumpulkan dana. Penerbit obligasi meminjam uang dari investor dan berjanji untuk membayar bunga secara berkala (dikenal sebagai kupon) serta mengembalikan pokok (nilai nominal) pada saat jatuh tempo.

Penilaian Obligasi (Bond Valuation): Penilaian obligasi melibatkan penghitungan nilai sekarang dari arus kas masa depan yang dihasilkan oleh obligasi. Arus kas ini termasuk pembayaran kupon berkala dan nilai nominal yang dibayarkan saat jatuh tempo. Nilai obligasi tergantung pada suku bunga pasar, tingkat kupon, dan jangka waktu sampai jatuh tempo. Rumus dasar penilaian obligasi adalah:
Nilai Obligasi=∑(Pembayaran Kupon(1+r)t)+Nilai Nominal(1+r)n\text{Nilai Obligasi} = \sum \left(\frac{\text{Pembayaran Kupon}}{(1 + r)^t}\right) + \frac{\text{Nilai Nominal}}{(1 + r)^n}Nilai Obligasi=∑((1+r)tPembayaran Kupon)+(1+r)nNilai Nominal

Di mana:

r adalah tingkat bunga pasar,

t adalah waktu pembayaran kupon,

n adalah jangka waktu obligasi.

Hasil Obligasi (Yield): Hasil obligasi mengukur return yang dihasilkan oleh obligasi bagi investor. Ada beberapa jenis hasil yang sering digunakan:

Current Yield: Mengukur hasil saat ini berdasarkan kupon tahunan dan harga pasar obligasi saat ini: Current Yield=Kupon TahunanHarga Obligasi Saat Ini\text{Current Yield} = \frac{\text{Kupon Tahunan}}{\text{Harga Obligasi Saat Ini}}Current Yield=Harga Obligasi Saat IniKupon Tahunan

Yield to Maturity (YTM): Menghitung total return yang diharapkan investor jika memegang obligasi hingga jatuh tempo. YTM memperhitungkan semua pembayaran kupon, serta perbedaan antara harga beli dan nilai nominal.

Hubungan antara Harga Obligasi dan Suku Bunga: Harga obligasi memiliki hubungan terbalik dengan suku bunga pasar. Ketika suku bunga naik, harga obligasi turun, dan sebaliknya. Ini karena nilai sekarang dari arus kas masa depan berkurang saat suku bunga naik.

Secara keseluruhan, penilaian obligasi dan hasil adalah alat penting dalam menentukan apakah sebuah obligasi memberikan nilai yang baik bagi investor.
Anomalous hydrodynamic interaction in a quasi-two-dimensional suspension

description: We have studied the correlated Brownian motion of micron-sized particles suspended in water and confined between two plates. The hydrodynamic interaction between the particles exhibits three anomalies. (i) The transverse coupling is negative, i.e., particles exert "anti-drag" on one another when moving perpendicular to their connecting line. (ii) The interaction decays with inter-particle distance r as 1/r^2, faster than in unconfined suspensions but slower than near a single wall. (iii) At large distances the pair interaction is independent of concentration within the experimental accuracy. The confined suspension thus provides an unusual example of long-range, yet essentially pairwise correlations even at high concentration. These effects are shown to arise from the two-dimensional dipolar form of the flow induced by single-particle motion.

description: The economic integration of migrants has become increasingly prioritised by European governments. However, Europe’s colonial past and orientalist narratives have contributed to the inevitable othering of migrants, even in the minds of those with the best of intentions. Guided by the self-categorisation theory, we postulate that those involved in supporting migrants to integrate in European societies implicitly categorise them as an out-group, potentially leading to suboptimal integration outcomes and the (inadvertent) exclusion of the very migrants they attempt to integrate. A case study of migrant entrepreneurship support initiatives in Berlin is illustrated as a qualitative, empirical example, providing some evidence for those arguments. The paper concludes with recommendations for practitioners and suggestions for further research.

description: Today, AI is being increasingly used to help human experts make decisions in high-stakes scenarios. In these scenarios, full automation is often undesirable, not only due to the significance of the outcome, but also because human experts can draw on their domain knowledge complementary to the model's to ensure task success. We refer to these scenarios as AI-assisted decision making, where the individual strengths of the human and the AI come together to optimize the joint decision outcome. A key to their success is to appropriately \textit{calibrate} human trust in the AI on a case-by-case basis; knowing when to trust or distrust the AI allows the human expert to appropriately apply their knowledge, improving decision outcomes in cases where the model is likely to perform poorly. This research conducts a case study of AI-assisted decision making in which humans and AI have comparable performance alone, and explores whether features that reveal case-specific model information can calibrate trust and improve the joint performance of the human and AI. Specifically, we study the effect of showing confidence score and local explanation for a particular prediction. Through two human experiments, we show that confidence score can help calibrate people's trust in an AI model, but trust calibration alone is not sufficient to improve AI-assisted decision making, which may also depend on whether the human can bring in enough unique knowledge to complement the AI's errors. We also highlight the problems in using local explanation for AI-assisted decision making scenarios and invite the research community to explore new approaches to explainability for calibrating human trust in AI.

description: We introduce CS1QA, a dataset for code-based question answering in the programming education domain. CS1QA consists of 9,237 question-answer pairs gathered from chat logs in an introductory programming class using Python, and 17,698 unannotated chat data with code. Each question is accompanied with the student's code, and the portion of the code relevant to answering the question. We carefully design the annotation process to construct CS1QA, and analyze the collected dataset in detail. The tasks for CS1QA are to predict the question type, the relevant code snippet given the question and the code and retrieving an answer from the annotated corpus. Results for the experiments on several baseline models are reported and thoroughly analyzed. The tasks for CS1QA challenge models to understand both the code and natural language. This unique dataset can be used as a benchmark for source code comprehension and question answering in the educational setting.

description: The double-cubane cluster (DCC) refers to an [Fe8S9] iron-sulfur complex that is otherwise only known to exist in nitrogenases. Containing a bridging µ2-S ligand, the DCC in the DCC-containing protein (DCCP) is covalently linked to the protein scaffold via six coordinating cysteine residues. In this study, the nature of spin coupling and the effect of spin states on the cluster’s geometry are investigated computationally. Using density functional theory (DFT) and a broken symmetry (BS) approach to study the electronic ground state of the system, we computed the exchange interaction between the spin-coupled spins of the four FeFe dimers contained in the DCC. This treatment yields results that are in excellent agreement with both computed and experimentally determined exchange parameters for analogously coupled di-iron complexes. Hybrid quantum mechanical (QM)/molecular mechanical (MM) geometry optimizations show that cubane cluster A closest to charged amino acid side chains (Arg312, Glu140, Lys146) is less compact than cluster B, indicating that electrons of the same spin in a charged environment seek maximum separation. Overall, this study provides the community with a fundamental reference for subsequent studies of DCCP, as well as for investigations of other [Fe8S9]-containing enzymes.

description: Ligand-based pharmacophore modelling and virtual screening along with in vitro screening were performed as a rational strategy for the identification of novel compounds as apoptosis inducers and anticancer agents from the chemical database. Known apoptosis inducers were selected from the literature for generation of pharmacophore models, which were subjected to validation using Receiver operating characteristic (ROC) and Günere-Henry (GH) scoring methods. Based on highest fitness score of 4680.61, ROC value of 0.872 and GH score of 0.758, pharmacophore model-2 was selected as the best model. Model-2 as 3D search query was searched against the IBS database to find novel compounds as hits. Three hits were selected with a QFIT value more than 82 for in vitro screening as apoptosis inducers and anticancer agents. In vitro anticancer activity was performed using resazurin cell variability assay, and apoptosis inducing activity was determined using caspase-3 activation and annexin-FITC assays. One of the retrieved hit, STOCK5S-44056 demonstrated IC50 value of 23.56 µM in cell variability assay, and had EC50 value of 26.95 µM in caspase-3 activation assay. STOCK5S-44056 also indicated late stage induction of apoptosis in annexin assay. The results of in vitro activity revealed that STOCK5S-44056 has a potential to become anticancer agents.

description: It was recently suggested by A. Kapustin that turning on a $B$-field, and allowing some discrepancy between the left and and right-moving complex structures, must induce an identification of B-branes with holomorphic line bundles on a non-commutative complex torus. We translate the stability condition for the branes into this language and identify the stable topological branes with previously proposed non-commutative instanton equations. This involves certain topological identities whose derivation has become familiar in non-commutative field theory. It is crucial for these identities that the instantons are localized. We therefore explore the case of non-constant field strength, whose non-linearities are dealt with thanks to the rank-one Seiberg--Witten map.

 Caridina yulinica Cai & Ng, 1999:1620, figures 9–11 [type locality: Niuwo cave near Kuiyang Town, Yulin, Guangxi, China].
 Caridina mutata Cai & Ng, 1999:1624, figures 12, 13 [type locality: Fangcheng Town, Fangcheng County, Guangxi, China].
Material examined: 5 males (FSTC, 2001­07­01 to 05): cl 3.5–4.9 mm; 2 females (FSTC, 2001­07­06 to 7), cl 3.8–4.8 mm, near Mashi town, Jianghua County, Hunan province. 9 July 2001; 15 males (FSTC, 2004­07­01 to 15): cl 3.0– 5.1 mm; 10 females (FSTC, 2004­ 07­16 to 25), cl 3.3–5.2 mm, near Suocheng town, Lanshan County, Hunan province. 13 July 2004.
Diagnosis: Rostrum short, extending to end of second segment of antennular peduncle, dorsal border bearing 9–17 teeth, with 5–7 teeth situated behind the posterior orbital margin, 2–6 ventral teeth. Endopod of the first male pleopod rectangular, wide distally, inner margin concave, with a few thin marginal spiniform setae, outer margin straight; appendix interna well developed, arising from middle of endopod, just reaching end of endopod. Appendix masculina glabrous, reaching about 1/2 of endopod, inner margin and tip bearing numerous long spines; appendix interna reaching about half of appendix masculina. Eggs 0.63–0.72 x 0.99–1.09mm in diameter.
 Remarks: This species is an easily recognized atyid shrimp of Hunan Province distinguished by its unusually longer stylocerite, which reaching beyond end of basal segment of antennular peduncle. The taxonomy of this species was reviewed by Cai (1999). Liang (2004) subsequently synonymized Caridina yulinica and Caridina mutata with Caridina cantonensis. The present materials agree well with the previous description (Yu, 1938; Cai, 1999; Liang, 2004). It is a common atyid shrimp in southern China. This is the first record of the species from Hunan Province. It has been found in mountain streams, and usually collected together with Marcobrachium nipponense (De Haan, 1849). With the striking reddish­brown transverse bands on the body, Caridina cantonensis has been cultivated in the aquarium in Guangdong and Shanghai in recent years.
Distribution: Guangdong, Guangxi, Hunan, and Hongkong; Vietnam.

description: A novel coronavirus recently identified in Wuhan, China (2019-nCoV) has resulted in an increasing number of patients globally, and has become a highly lethal pathogenic member of the coronavirus family affecting humans. 2019-nCoV has established itself as one of the most threatening pandemics that human beings have faced, and therefore analysis and evaluation of all possible responses against infection is required. One such strategy includes utilizing the knowledge gained from the SARS and MERS outbreaks regarding existing antivirals. Indicating a potential for success, one of the drugs, remdesivir, under repurposing studies, has shown positive results in initial clinical studies. Therefore, in the current work, the authors have attempted to utilize the remdesivir–RdRp complex – RdRp (RNA-dependent RNA polymerase) being the putative target for remdesivir – to screen a library of the already reported RdRp inhibitor database. Further clustering on the basis of structural features and scoring refinement was performed to filter out false positive hits. Finally, molecular dynamics simulation was carried out to validate the identification of hits as RdRp inhibitors against novel coronavirus 2019-nCoV. The results yielded two putative hits which can inhibit RdRp with better potency than remdesivir, subject to further biological evaluation.

description: Two constructive proofs on d-majorization and thermo-majorization are provided. In the first part, we present a diagrammatic proof of the equivalence between d-majorization and the existence of a proper stochastic matrix. We explicitly construct the desired stochastic matrix by using a graphical argument. In the second part, we present a constructive proof of the equivalence between the Gibbs-preserving map and thermal operation in classical systems. We construct the desired thermal operation and a heat bath which emulates any Gibbs-preserving map with an arbitrary accuracy.

description: Symmetry considerations are of extreme importance to the topological properties of crystals. A crystal field splitting δ yields Dirac nodes near the Brillouin zone center in Cd3As2, but its value has yet to be determined with precision. We study the band structure of Cd3As2 using magnetooptical infrared spectroscopy measurements on epilayers with low carrier density grown by molecular beam epitaxy. By combining angular dependent cyclotron resonance with Landau level spectroscopy measurements in the Faraday geometry, we determine that δ is positive and equal to 15+/-5 meV in Cd3As2. Our results lead to a more accurate knowledge of the details of the band structure of this Dirac semimetal such as the position its Dirac nodes in momentum space and their splitting into Weyl nodes under a magnetic field.

description: Sigma-2 (σ2) receptor is a transmembrane protein shown to be linked with neurodegenerative diseases and cancer development. Thus, it emerges as a potential biological target for the advancement of anticancer and anti-Alzheimer’s agents. The current study was aimed to identify potential σ2 receptor ligands using integrated computational approaches including homology modelling, combined pharmacophore- and docking-based virtual screening, and molecular dynamics (MD) simulation. Pharmacophore-based screening was conducted against a database composed of 20,523 small natural and natural-like products. In total, 1200 structures were found to satisfy the required pharmacophore features and were then exposed to docking-based screening against the generated homology model of σ2 receptor. On the basis of the pharmacophore fit scores, docking scores, and mechanism of binding interaction, 20 potential hits were retained. Five promising candidates were selected (SR84, SR823, SR300, SR413, and SR530) on the basis of their binding score and interaction. Further, in silico ADMET profiling of these compounds showed that the selected compounds possess favourable ADME properties with low toxicity risk. The mechanism of interaction of these compounds with σ2 receptor as well as their binding stability were characterized by MD simulation.

description: We first consider various methods for the indirect implementation of unitary gates. We apply these methods to rederive the universality of 4-qubit measurements based on a scheme much simpler than Nielsen's original construction [quant-ph/0108020]. Then, we prove the universality of simple discrete sets of 2-qubit measurements, again using a scheme simplifying the initial construction [quant-ph/0111122]. Finally, we show how to use a single 4-qubit measurement to achieve universal quantum computation, and outline a proof for the universality of almost all maximally entangling 4-qubit measurements.

title: Interactions of flavones and related compounds with nucleic acids.
Creators: name: Ragazzon, Patricia Alejandra
Publisher: name: The Open University
Year: 2006

description: This project focused on a group of active ingredients isolated from herbal medicines, most of them flavonoids, as a foundation for the development of new anticancer drugs. Interactions between these compounds and genomic DNA, synthetic polynucleotides, or higher order DNA isoforms (triple and quadruple helical forms) have been studied using a range of physicochemical and biological techniques. The studies demonstrated that flavonoids and isoflavonoids bind to the various nucleic acid forms with weak or moderate affinities and no significant specificity, apart from quercetin that demonstrated a differential binding for G-quadruplex structures.

Rational drug design has been subsequently employed to elucidate the mode of binding and novel compounds have been synthesized in order to provide precise structure-activity related studies and result in a second generation of chemotherapeutic anticancer agents with improved properties. Interaction with DNA is thought to involve the planar ring structures. The double bond of the O in C4 in a flavone scaffold gives planarity to the molecule, and this allows the molecule to intercalate between the bases in the different nucleic acid structures. The comparison between flavone, flavanone and isoflavonoid indicates that the position of the B ring and the double bond in the C ring are important for the interactions with DNA. Introduction of nitrogen in the ring did not improve the binding but tertiary amines improved binding 100 fold. Introduction of sulfur produced two binding constants. Position 7 in the A ring of the flavones is extremely relevant for the binding to the nucleic acids, but substitutions in the B ring did not improve the binding. Methoxylation or acetoxylation in positions 5 and 7 decreased the affinity for DNA. Novel compounds were tested for their specificity against different DNA isoforms and their anticancer activity in various tumour cell lines.

description: By means of a nonlinear separation of the variables in the governing full set of the magnetohydrodynamic (MHD) equations for axisymmetric plasmas we analyse an exact model for magnetized and rotating outflows which are hotter and overpressured at their axis. These outflows start subsonically and subAlfvénically from the central gravitating source and its surrounding accretion disk. Subsequently, they accelerate thermally and magnetocentrifugally and thus cross the appropriate MHD critical points, reaching high values of the Alfvén Mach number. Three types of solutions are found : (a) collimated jet-type outflows from efficient magnetic rotators with the flow confined by the magnetic hoop stress; (b) radially expanding wind-type outflows analogous to the solar wind, from inefficient magnetic rotators or strongly overpressured sources; (c) terminated solutions with increasing amplitude of oscillations in the width of the beam. In contrast to previously studied underpressured outflows, the transition from collimated jets to uncollimated winds is not continuous in the appropriate parametric space with a gap where no stationary solution is found. Superfast at infinity solutions are filtered by three critical surfaces corresponding to the three known limiting characteristics or separatrices of MHD wind theory. Collimated and terminated solutions cross the slow, Alfvén and fast magneto-acoustic critical points. Radially expanding solutions cross the slow and Alfvén critical points while the last boundary condition is imposed by requiring that the pressure vanishes at infinity.
