description: The eROSITA instrument on board Spectrum-Roentgen-Gamma has completed four scans of the X-ray sky, leading to the detection of almost one million X-ray sources in eRASS1 only, including multiple new X-ray binary candidates. We report on analysis of the X-ray binary 1eRASS J085039.9-421151, using a ~55\,ks long NuSTAR observation, following its detection in each eROSITA scan. Analysis of the eROSITA and NuSTAR X-ray spectra in combination with X-shooter data of the optical counterpart provide evidence of an X-ray binary with a red supergiant (RSG) companion, confirming previous results, although we determine a cooler spectral type of M2-3, owing to the presence of TiO bands in the optical and near infrared spectra. The X-ray spectrum is well-described by an absorbed power law with a high energy cutoff typically applied for accreting high mass X-ray binaries. In addition, we detect a strong fluorescent neutral iron line with an equivalent width of ~700\,eV and an absorption edge, the latter indicating strong absorption by a partial covering component. It is unclear if the partial absorber is ionised. There is no significant evidence of a cyclotron resonant scattering feature. We do not detect any pulsations in the NuSTAR lightcurves, possibly on account of a large spin period that goes undetected due to insufficient statistics at low frequencies or potentially large absorption that causes pulsations to be smeared out. Even so, the low persistent luminosity, the spectral parameters observed (photon index, $\Gamma<1.0$), and the minuscule likelihood of detection of RSG-black hole systems, suggest that the compact object is a neutron star.

Description
Sponge in encrusting stage (β) (IMG0830, PdO19, PdO22, PO22, PO23 and PO64) and massive stage (γ) (IMGO913 and PO23). Two main chromatic varieties, shifting from ochre to orange (Fig. 15 A–B) to pale or light yellow (Fig. 15 C–D). Specimens, dried and alcohol preserved, are brown in color. The consistence of the papillae and of the γ-stage forms is firm and incompressible. The body of the γ-stage is cavernous. The sponges in the γ-stage are full of foreign material, also derived by their erosion and engulfing activity.
SKELETON. In the papillae, long and slim tylostyles are organized in palisade, in other parts the skeleton is more confused.
SPICULES. Tylostyles (Fig. 15E) with a prominent head (Fig. 15F); in numerous tylostyles the axial canal and the vesicle in the tylo are evident. They measure 295–(307.87)–345 μm×2.5–(6.7)–7.5 μm.
Remarks
This species was recently described by Samaai et al. (2019) from South Africa; it is widespread in the studied area where it develops a sort of biogenic fence up to 50 cm high.

description: The Affordable Care Act was signed into law in 2010, expanding Medicaid and improving access to care for millions of low-income Americans. Fewer uninsured individuals reduced the cost of uncompensated care, consequently improving the financial health of hospitals. We hypothesize that this amelioration in hospital finances resulted in a marked improvement of quality measures in states that chose to expand Medicaid. To our knowledge, the impact of Medicaid expansion on the Medicare population has not been investigated. Using a difference-in-difference analysis, we compare readmission rates for four measures from the Hospital Readmission Reduction Program: acute myocardial infarction, pneumonia, heart failure, and coronary artery bypass graft surgery. Our analysis provides evidence that between 2013 and 2021 expansion states improved hospital quality relative to non-expansion states as it relates to acute myocardial infarction readmissions (p = 0.015) and coronary artery bypass graft surgery readmissions (p = 0.039). Our analysis provides some evidence that expanding Medicaid improved hospital quality, as measured by a reduction in readmission rates. Using visualizations, we provide some evidence that hospital quality improved for the other two measures as well. We believe that a refinement of our estimation method and an improved dataset will increase our chances of finding significant results for these two other measures.

description: We present the analysis of 200 ks NuSTAR observation of the Vela pulsar and the pulsar wind nebula (PWN). The phase-resolved spectra corresponding to two main peaks in the folded pulse profile differ significantly. The spectrum of Peak 1 is significantly harder than that of Peak 2 in qualitative agreement with the earlier Rossi X-ray Timing Explorer results. However, for both spectra, the values of power-law (PL) fit photon indices, ?, are noticeably larger than the previously reported values. The harder (Peak 1) spectrum has ? = 1.10 ± 0.15, which is close to those measured for the bright inner jets of the PWN. We used the off-pulse interval to remove the emission from the pulsar and measure the compact PWN spectrum in hard X-rays. We also measured the spectrum from the southwestern region of the PWN, which is resolved by NuSTAR from the compact PWN. For both regions, we fit the NuSTAR spectra by themselves and together with the Chandra X-ray Observatory spectra. We found that the PWN spectrum (for both regions) requires a more complex model than a simple PL. The fits to compact PWN spectrum favor an exponentially cutoff PL model, with E c ? 50 keV over the broken PL model. The observed synchrotron photon energies imply electrons accelerated to ?150 TeV.

Material examined
PONTA DO OURO • 1 very small sample covering a hydroid; 26°49′29.579″ S, 32°53′51.072″ E; Blacks; 19.2 m deep; 4 Feb. 2017; Cerrano leg.; PO10 • 1 small fragment; 26°49′16.561″ S, 32°53′52.979″ E; Tea Garden; 19.7 m deep; 6 Mar. 2017; Cerrano leg.; PO78.
Description
The sponge is massive (Fig. 21 A–B), digitiform and arborescent (Fig. 21C). The exhalant channels converge in numerous, large oscula (Fig. 21 A–B). The color may vary from bright orange to vivid red (Fig. 21 A–C). Both samples preserved in alcohol changed their color to beige. The surface is verrucose and the consistence is elastic.
SKELETON. The ectosome consists of a layer of small styles. The choanosome is formed by an irregular reticulation from pauci- to multispicular primary fibers, 52–73 µm in section, and secondary unispicular fibers, 24–41 µm. Both are spongin rich and are cored by smooth styles. Echinating acanthostyles are present on the primary fibers (Fig. 21D).
SPICULES. Smooth and straight styles (Fig. 21E), sometimes modified in subtylostyles, 82.5–(93.25, 11.8)– 137.5 µm × 4–(5.2, 0.7)– 6 µm; smooth and slightly curved styles (Fig. 21F), 70–(109.5, 23.4)– 147 µm × 4.5–(5.2, 0.7)– 6.1 µm; straight acanthostyles (Fig. 21G) with sharp spines on the terminal parts, close to the tips and scattered on the head, 40–(56.3, 10.3)– 72 µm; raphidiform toxas (Fig. 21H) slightly curved in the middle, 100–(104.5)– 120 µm ×4.75–(6)– 7.5 µm; palmate chelae (Fig. 21I) 5–7.5 µm.
Remarks
Clathria (Thalysias) hirsuta Hooper & Levi, 1993 was exclusively known from New Caledonia and Australia (Great Barrier Reef); this is the first record in the Indian Ocean. The spicule shape, size and the morphology fit the original description of the species. However, Hooper & Levi (1993) recognized two distinct populations, with some morphological differences, one from Queensland and one from New Caledonia. The morphological characters (especially spicule size) make the specimens, here examined, closer to the population from New Caledonia.
On the specimen PO78 the hydroid Zyzzyzus warreni Calder, 1988 (Class Hydrozoa, Phylum Cnidaria) was detected.

Material examined
PONTA DO OURO • 1 sample preserved dry; 26°46′39.864″ S, 32°55′25.319″ E; Cloud break; 34 m deep; 22 May 2015; Torsani leg.; IMG0826 • several fragments, the larger about 6 cm long; 26°49′17.512″ S, 32°53′42.511″ E; Kev’s; 23.4 m deep; 3 Feb. 2017; Cerrano leg.; PO3.
Description
The live sponge is massive, with rounded conules covering the surface (Fig. 22A). The color is redorange. The fragments preserved in alcohol are beige in color; they have a digitate-conulose surface and a very firm consistence.
SKELETON. The ectosome consists of a paratangential layer of thin styles (Fig. 22B). The choanosome (Fig. 22C) is made by a reticulation of multispicular primary fibers, 70–125 µm in section, and secondary fibers, 23–35 µm, forming irregularly rounded meshes around 150 µm wide. The fibers have a core of styles and are echinated by acanthostyles.
SPICULES. Slightly curved and smooth styles (Fig. 22D), sometimes straight, 145–(176.5, 21.4)– 210 µm × 6–(7, 1.1)– 9.5 µm; longer and straight subtylote styles (Fig. 22E), microspined or smooth on the head, 198.5–(230, 15.5)– 250 µm ×4.5–(6.5, 0.8)– 7.5 µm; subtylote acanthostyles (Fig. 22F), with smooth neck, 47.5–(51, 4.9)– 72.5 µm; very thin toxas (Fig. 22G), bent in the middle, 143–181 µm; palmate isochelae (Fig. 22H) 11.3–14.6 µm.
Remarks
The specimens fit the original description of Clathria (Thalysias) vulpina (Lamarck, 1814) from Australia. The species has already been found in the area (Thomas 1979). On the specimen PO3, the hydroid Zyzzyzus warreni Calder, 1988 (Class Hydrozoa, Phylum Cnidaria) grew.

description: Halieus leucogaster Meyen, 1834a: 112, pl. 22.
Now: Phalacrocorax carbo sinensis Staunton, 1796. See Ogilvie-Grant (1898: 343). For the authorship of sinensis see Mlíkovský (2011b).
Holotype: ZMB 14227 (Lichtenstein 1832, Nr. 80 sub “ Halieus ”), skin, collected by Meyen in “ October ” [= 25–27 October 1831; see below] in “ Manila ” [= Truro Shoal, South China Sea] (see below).
Type locality. Meyen (1834a) did not specify where he collected the holotype, but mentioned (p. 113) that “ Bei Gelegenheit eines sehr heftigen Sturms wurde dieser Vogel auf das Deck unsers [sic] Schiffes geworfen.” (“the bird was thrown on the deck of our ship during a heavy storm”). Lichtenstein (1832) imprecisely stated that the bird was collected in “ October ” at “ Manila ”. The Prinzess Louise encountered a heavy storm on 25–27 October 1831 (Meyen 1835: 290, Berghaus 1842: 79–80), when it was north-west of Scarborough Reef [15.13°N, 117.77°E] in the area of Truro Shoal [16.32°N, 116.68°E] on its way from Manila, Philippines, to Guangzhou, China. We thus ascertain the type locality as the South China Sea at Truro Shoal.

Ciocalypta heterostyla Hentschel, 1912: 424, pl. 14, fig. 3, pl. 21, fig. 58.
Material examined
PONTA DO OURO • 1 fragment with some fistules and the basal portion, about 2 ×1× 1 cm; 26°49′55.65″ S, 32°53′13.41″ E; Three Sisters; 23.9 m deep; 21 Feb. 2017; Cerrano leg.; PO63.
Description
The sponge is burrowed under the sediment and only its erect fistules are visible (Fig. 24A). These are whitish, transparent, showing the yellow, internal axis. The alcohol preserved sample is a thin massive base bearing fistules; the color is dirty white. The consistence is really soft and extremely compressible.
SKELETON. The skeleton of the basal part consists of multispicular tracts in confusion and grains of sediment (Fig. 24B). The skeleton of fistules (Fig. 24C) has a central axis of densely packed spicules, about 100 µm in section, close to the base, and gradually thinner towards the apex of the fistula. From the axis, multispicular fibers, 20–25 µm in section, develop, opening in fans close to the surface (Fig. 24C).
SPICULES. The styles are in a wide range of shapes (straight, slightly curved, sinuous) and size, 285– (351.5, 63.7)– 495 µm ×5–(8.3, 1.5)– 10 µm (Fig. 24 D–E).
Remarks
The presence on the surface of numerous finger-shaped and transparent fistulae with a central axis and the general structure of the skeleton are typical features of the genus Ciocalypta Bowerbank, 1862. To date, there are 26 species of Ciocalypta described (Van Soest et al. 2019). The specimen shares with Ciocalypta heterostyla Hentschel, 1912 the spicule size and shape, the skeleton organization and the
general morphology. This species is known from Indonesia and Arafura Sea (Van Soest et al. 2019) and, therefore, this is the first record for the Indian Ocean.

description: Autonomous navigation in unstructured outdoor environments is inherently challenging due to the presence of asymmetric traversal costs, such as varying energy expenditures for uphill versus downhill movement. Traditional reinforcement learning methods often assume symmetric costs, which can lead to suboptimal navigation paths and increased safety risks in real-world scenarios. In this paper, we introduce QuasiNav, a novel reinforcement learning framework that integrates quasimetric embeddings to explicitly model asymmetric costs and guide efficient, safe navigation. QuasiNav formulates the navigation problem as a constrained Markov decision process (CMDP) and employs quasimetric embeddings to capture directionally dependent costs, allowing for a more accurate representation of the terrain. This approach is combined with adaptive constraint tightening within a constrained policy optimization framework to dynamically enforce safety constraints during learning. We validate QuasiNav across three challenging navigation scenarios-undulating terrains, asymmetric hill traversal, and directionally dependent terrain traversal-demonstrating its effectiveness in both simulated and real-world environments. Experimental results show that QuasiNav significantly outperforms conventional methods, achieving higher success rates, improved energy efficiency, and better adherence to safety constraints.

Description
The sponge is lamellate, foliose; color is dark red to violet (Fig. 27 A–B). On the surface, two specimens present algal turf. The samples preserved in alcohol changed color to beige; the dried samples are whitish, light brown; in the dried state, spicule tracts create an irregular pattern and thick lines on the surface. The samples have a micro-bristly surface and an elastic consistence.
SKELETON. The ectosome is constituted of a layer of densely packed euasters (Fig. 27C). the choanosome with plumo-reticulate tracts is formed by megascleres (Fig. 27D), without a well-marked differentiation between axial and extra-axial regions.
SPICULES. The megascleres are constituted by strongyloxeas and oxeas (Fig. 27E), with a wide range of intermediate forms, 590–(842.5, 100.8)– 980 µm ×10–(17.25, 4.3)– 25.5 µm; strongylasters with at least five rays (Fig. 27F) with microspined rays 7.5–(12.4, 3.6)– 20 µm, and smooth oxyasters 5–(8.9, 3.8)– 25 µm (Fig. 27G).
Remarks
The examined material fits with the species Hemiasterella complicata Topsent, 1919. This is a species with a strict distribution, confined to East Africa and Madagascar (Burton 1959; Vacelet et al. 1976; Pulitzer-Finali 1993). This species is also similar to Hemiasterella vasiformis (Kirkpatrick, 1903) (Topsent 1919), recently recorded by Samaai et al. (2019) in South Africa; as a consequence, a revision of the genus Hemiasterella and a genetic analysis would be necessary in order to clarify the possible synonymy.

Description
Thin encrusting sponge, dark blue colored; it covers colonies of the octocoral Carijoa sp. (Class Anthozoa, Phylum Cnidaria) (Fig. 26A). Whitish in ethanol, bluish in formalin. The surface is microhispid.
SKELETON. It is formed by brushes of spicules which, projecting also over the surface, cause the microhispid surface (Fig. 26B).
SPICULES. Tylostyles with heads variable in shape, from mushroom-shape to plurilobate (Fig. 26C). The size is 77.5–(255, 81.7)– 330 µm ×1.25–(4.1, 0.9)– 5 µm.
Remarks
The peculiar shape of the heads, the general morphology and the skeletal structure are typical characters of species in the genus Terpios Duchassaing & Michelotti, 1864. The specimen fits the description of Terpios granulosus (Bergquist, 1967) from Hawaii later also recorded by Vacelet & Vasseur (1971) and Barnes & Bell (2002) from Kenya and Madagascar.

description: The paper introduces a (universal) C*-algebra of continuous functions vanishing at infinity on the n-dimensional quantum complex space. To this end, the well-behaved Hilbert space representations of the defining relations are classified. Then these representations are realized by multiplication operators on an L2-space. The C*-algebra of continuous functions vanishing at infinity is defined by considering a *-algebra such that its classical counterpart separates the points of the n-dimensional complex space and by taking the operator norm closure of a universal representation of this algebra.

description: In this study, we seek to understand how macroeconomic factors such as GDP, inflation, Unemployment Insurance, and S&P 500 index; as well as microeconomic factors such as health, race, and educational attainment impacted the unemployment rate for about 20 years in the United States. Our research question is to identify which factor(s) contributed the most to the unemployment rate surge using linear regression. Results from our studies showed that GDP (negative), inflation (positive), Unemployment Insurance (contrary to popular opinion; negative), and S&P 500 index (negative) were all significant factors, with inflation being the most important one. As for health issue factors, our model produced resultant correlation scores for occurrences of Cardiovascular Disease, Neurological Disease, and Interpersonal Violence with unemployment. Race as a factor showed a huge discrepancies in the unemployment rate between Black Americans compared to their counterparts. Asians had the lowest unemployment rate throughout the years. As for education attainment, results showed that having a higher education attainment significantly reduced one chance of unemployment. People with higher degrees had the lowest unemployment rate. Results of this study will be beneficial for policymakers and researchers in understanding the unemployment rate during the pandemic.
