ABSTRACT
Studying the kinematics and mass modelling of galaxies from H i 21 cm data provides valuable insights into the properties of both the baryonic components and the dark matter halo in nearby galaxies. Despite many observational studies, mass modelling of galaxies remains challenging due to different limitations. For example, most of the previous studies involving mass modelling are based on rotation curves derived from 2D velocity fields from H i or H α spectroscopic observation which are often affected by beam smearing and projection effect. However, kinematic modelling done by fitting the ‘Tilted ring model’ to 3D data cube is not affected by these issues. In this study, we present and compare 3D kinematic modelling of a pilot sample of 11 galaxies from the GMRT archive atomic gas survey (GARCIA) using two different publicly available pipelines. We model the observed H i rotation curve using 3.6-μm infrared data and SDSS r-band data for stellar contribution, H i surface density profile for gas, and Navarro–Frenk–White profile for dark matter halo; and employ the Markov chain Monte Carlo optimization method for parameter estimation. Further, to validate our analysis, we revisit important scaling relations, e.g. the Mgas–Mstar relation, Mstar–Mhalo relation, Mgas–Mhalo relation and Baryonic Tully–Fisher relation. The scaling relations from our analysis are broadly consistent with that reported in the literature. A larger sample of galaxies from GARCIA in the near future will allow studying these scaling relations in greater details.

ABSTRACT
When the first galaxies formed and starlight escaped into the intergalactic medium to reionize it, galaxy formation and reionization were both highly inhomogeneous in time and space, and fully coupled by mutual feedback. To show how this imprinted the UV luminosity function (UVLF) of reionization-era galaxies, we use our large-scale, radiation-hydrodynamics simulation CoDa II to derive the time- and space-varying halo mass function and UVLF, from z ≃ 6–15. That UVLF correlates strongly with local reionization redshift: earlier-reionizing regions have UVLFs that are higher, more extended to brighter magnitudes, and flatter at the faint end than later-reionizing regions observed at the same z. In general, as a region reionizes, the faint-end slope of its local UVLF flattens, and, by z = 6 (when reionization ended), the global UVLF, too, exhibits a flattened faint-end slope, ‘rolling-over’ at MUV ≳ −17. CoDa II’s UVLF is broadly consistent with cluster-lensed galaxy observations of the Hubble Frontier Fields at z = 6–8, including the faint end, except for the faintest data point at z = 6, based on one galaxy at MUV = −12.5. According to CoDa II, the probability of observing the latter is $\sim 5~{{\ \rm per\ cent}}$. However, the effective volume searched at this magnitude is very small, and is thus subject to significant cosmic variance. We find that previous methods adopted to calculate the uncertainty due to cosmic variance underestimated it on such small scales by a factor of 2–4, primarily by underestimating the variance in halo abundance when the sample volume is small.
The formation of supermassive black holes from Population III.1 seeds. II. Evolution to the local universe
Authors: Singh Jasbir , Monaco Pierluigi , Tan Jonathan C 
Published: August 2023

ABSTRACT
We present predictions for cosmic evolution of populations of supermassive black holes (SMBHs) forming from Population III.1 seeds, i.e. early, metal-free dark matter minihaloes forming far from other sources, parametrized by isolation distance, diso. Extending previous work that explored this scenario to z = 10, we follow evolution of a $(60\, {\rm {Mpc}})^3$ volume to z = 0. We focus on evolution of SMBH comoving number densities, halo occupation fractions, angular clustering, and 3D clustering, exploring a range of diso constrained by observed local number densities of SMBHs. We also compute synthetic projected observational fields, in particular, a case comparable to the Hubble Ultra Deep Field. We compare Pop III.1 seeding to a simple halo mass threshold model, commonly adopted in cosmological simulations of galaxy formation. Major predictions of the Pop III.1 model include that all SMBHs form by z ∼ 25, after which their comoving number densities are near-constant, with low merger rates. Occupation fractions evolve to concentrate SMBHs in the most massive haloes by z = 0, but with rare cases of SMBHs in haloes down to $\sim 10^8\, M_\odot$. The diso scale at epoch of formation, e.g. $100\,$kpc-proper at z ∼ 30, i.e. $\sim 3\,$Mpc-comoving, is imprinted in the SMBH two-point angular correlation function, remaining discernible as a low-amplitude feature to z ∼ 1. The SMBH 3D two-point correlation function at z = 0 also shows lower amplitude compared to equivalently massive haloes. We discuss prospects for testing these predictions with observational surveys of SMBH populations.

ABSTRACT
From a purely photometric perspective galaxies are generally decomposed into a bulge+disc system, with bulges being dispersion-dominated and discs rotationally supported. However, recent observations have demonstrated that such a framework oversimplifies complexity, especially if one considers galaxy kinematics. To address this issue we introduced with the GPU-based code bang a novel approach that employs analytical potential-density pairs as galactic components, allowing for a computationally fast, still reliable fit of the morphological and kinematic properties of galaxies. Here we apply bang to the SDSS-MaNGA survey, estimating key parameters such as mass, radial extensions, and dynamics, for both bulges and discs of +10 000 objects. We test our methodology against a smaller subsample of galaxies independently analysed with an orbit-based algorithm, finding agreement in the recovered total stellar mass. We also manage to reproduce well-established scaling relations, demonstrating how proper dynamical modelling can result in tighter correlations and provide corrections to standard approaches. Finally, we propose a more general way of decomposing galaxies into ‘hot’ and ‘cold’ components, showing a correlation with orbit-based approaches and visually determined morphological type. Unexpected tails in the ‘hot-to-total’ mass-ratio distribution are present for galaxies of all morphologies, possibly due to visual morphology misclassifications.

ABSTRACTThe complex interaction between shocks and plasma turbulence is extremely important to address crucial features of energy conversion in a broad range of astrophysical systems. We study the interaction between a supercritical, perpendicular shock and pre-existing, fully developed plasma turbulence, employing a novel combination of magnetohydrodynamic and small-scale, hybrid-kinetic simulations where a shock is propagating through a turbulent medium. The variability of the shock front in the unperturbed case and for two levels of upstream fluctuations is addressed. We find that the behaviour of shock ripples, i.e. shock surface fluctuations with short (a few ion skin depths, di) wavelengths, is modified by the presence of pre-existing turbulence, which also induces strong corrugations of the shock front at larger scales. We link this complex behaviour of the shock front and the shock downstream structuring with the proton temperature anisotropies produced in the shock–turbulence system. Finally, we put our modelling effort in the context of spacecraft observations, elucidating the role of novel cross-scale, multispacecraft measurements in resolving shock front irregularities at different scales. These results are relevant for a broad range of astrophysical systems characterized by the presence of shock waves interacting with plasma turbulence.
Why are quasi-periodic eruptions only found in low-mass galaxies?
Authors: King Andrew 
Published: August 2023

ABSTRACT
I consider the current sample of galaxy nuclei producing quasi-periodic eruptions (QPEs). If the quasi-period results from the orbital motion of a star around the central black hole, the dearth of associated black hole masses ≳106 M⊙ places tight constraints on models. It disfavours those assuming wide orbits and small eccentricities, because there is ample volume within pericentre to allow significantly more massive holes in QPE systems than are currently observed. If instead the orbiting star is assumed to pass close to the black hole, the same lack of large black hole masses strongly suggests that the stellar orbits must be significantly eccentric, with 1 − e ≲ few × 10−2. This favours a tidal disruption near-miss picture where QPEs result from repeated accretion from an orbiting star (in practice a white dwarf) losing orbital angular momentum to gravitational radiation, even though this is not assumed in deriving the eccentricity constraint. Given the tight constraints resulting from the current small observed sample, attempts to find QPE systems in more massive galaxies are clearly important.

ABSTRACT
The unsuitable disposal of plastic wastes has caused serious environmental pollution, and finding a green manner to address this problem has aroused wide concern. Plastic wastes, especially polyolefin wastes, are rich in carbon and hydrogen, and chemical recycling shows distinct advantages in their conversion into olefins and realizes a closed-loop cycling of plastic wastes. Plastic wastes should be labeled before disposal. The necessity for, and methods of, pretreatment are introduced in this paper and the whole recycling process of polyolefin wastes is also summarized. As the core technology pyrolysis, including thermal, catalytic and solvolysis processes, is introduced in detail due to its potential for future development. We also briefly describe the feasible strategies of pyrolytic oil refining and life cycle assessment of the chemical recycling process. In addition, suggestions and perspectives concerning the industrial improvement of polyolefin chemical recycling are proposed.

Abstract
Breast cancer is affecting millions of people worldwide. If not appropriately handled, the side effects of different modalities of cancer treatment can negatively impact patients’ quality of life and cause treatment interruptions. In recent years, mobile health (mHealth) interventions have shown promising opportunities to support breast cancer care. Numerous studies implemented mobile health interventions aiming to support patients with breast cancer, for example, through physical activity promotion or educational content. Nonetheless, current literature reveals that real-world evidence for the actual benefits remains unclear. In this systematic review, we focus on analyzing the methodology used in recent studies to determine the effects of mHealth applications and wearable devices on the outcome of patients with breast cancer. We followed the PRISMA guideline for the selection, analysis, and reporting of relevant studies found in the databases of Medline, Scopus, Web of Science, and Cochrane Library. A total of 276 unique records were identified, and 20 studies met the inclusion criteria. Study quality was assessed with the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. While many of the studies used standardized questionnaires as patient-reported outcome measures, there was minimal use of objective measurements, such as activity sensors. Adoption, drop-out rates, and usage behavior of users of the mobile health intervention were often not reported. Future work should clearly define the focus and desired outcome of mHealth interventions and select outcome measures accordingly. Greater transparency facilitates the interpretation of results and conclusions about the real-world evidence of mobile health in breast cancer care.
Characteristics of direct-to-consumer platforms offering erectile dysfunction treatment
Authors: Brink Sarah M , Iarajuli Teona , Shin David 
Published: August 2023

Abstract

Background
Due to the sensitivity and potential embarrassment of discussing erectile dysfunction (ED) in person, men are seeking treatment online.

Aims
We sought to compare offerings of direct-to-consumer (DTC) platforms for ED treatment with respect to consultation, pricing, services, and privacy policy.

Methods
Google was queried to identify DTC platforms offering ED treatment with the keywords: “telehealth erectile dysfunction,” “telemedicine erectile dysfunction,” and “online erectile dysfunction.” Inclusion criteria were as follows: serving a majority of U.S. states, existing online only, providing both the consultation and prescription for phosphodiesterase type 5 inhibitors, and delivering the prescription to the patient.

Results
Fifteen DTC platforms met criteria. Ten provided free consultations; 4 bundled the consultation fee with the first month of the prescription, with 1 of these functioning as a subscription service. Fourteen (93%) relied on online intake forms and 10 (67%) advertised review by the prescriber within 2 business days. Only 4 (27%) platforms explicitly advertised physician-only consults. Direct contact with the prescriber would only occur if needed or if required by state law at 8 (53%) platforms. Purchasing sildenafil and tadalafil was advertised on all platforms. Minimum prices of sildenafil ranged from $0.50 to $35/pill (mean $5.16/pill, median $2.65/pill); tadalafil ranged from $0.50 to $9.80/pill (mean $4.70/pill, median $3.21/pill). In addition to ED therapy, 13 (86%) platforms offered treatment for other men’s health issues. All platforms included a website privacy policy, but only 10 (67%) mentioned Health Insurance Portability and Accountability Act compliance, with 2 of these claiming to not be covered entities.

Conclusion
Although DTC platforms are transparent with phosphodiesterase type 5 inhibitor medication and subscription pricing information, few offer direct contact with a physician to further discuss issues related to ED after completion of the online intake form. For comprehensive evaluation of ED in Health Insurance Portability and Accountability Act–compliant settings, in-person or telemedicine visits should be arranged with men’s physicians.

AbstractRecent advances in gene therapy have brought novel treatment options for cancer. However, the full potential of this approach has yet to be unlocked due to the limited payload capacity of commonly utilized viral vectors. Virus‐free DNA transposons, including piggyBac, have the potential to obviate these shortcomings. In this study, we improved a previously modified piggyBac system with superior transposition efficiency. We demonstrated that the internal domain sequences (IDS) within the 3′ terminal repeat domain of hyperactive piggyBac (hyPB) donor vector contain dominant enhancer elements. Plasmid‐free donor vector devoid of IDS was used in conjunction with a helper plasmid expressing Quantum PBase™ v2 to generate an optimal piggyBac system, Quantum pBac™ (qPB), for use in T cells. qPB outperformed hyPB in CD20/CD19 CAR‐T production in terms of performance as well as yield of the CAR‐T cells produced. Furthermore, qPB also produced CAR‐T cells with lower donor‐associated variabilities compared to lentiviral vector. Importantly, qPB yielded mainly CD8+ CAR‐TSCM cells, and the qPB‐produced CAR‐T cells effectively eliminated CD20/CD19‐expressing tumor cells both in vitro and in vivo. Our findings confirm qPB as a promising virus‐free vector system with an enhanced payload capacity to incorporate multiple genes. This highly efficient and potentially safe system will be expected to further advance gene therapy applications.

OBJECTIVE:
To systematically review the effects of postpartum health care–delivery strategies on health care utilization and maternal outcomes.

DATA SOURCES:
We searched Medline, EMBASE, CENTRAL, CINAHL, and ClinicalTrials.gov for studies in the United States or Canada from inception to November 16, 2022.

METHODS OF STUDY SELECTION:
We used duplicate screening for studies comparing health care–delivery strategies for routine postpartum care on health care utilization and maternal outcomes. We selected health care utilization, clinical, and harm outcomes prioritized by stakeholder panels.

TABULATION, INTEGRATION, AND RESULTS:
We found 64 eligible studies (50 randomized controlled trials, 14 nonrandomized comparative studies; N=543,480). For general postpartum care, care location (clinic, at home, by telephone) did not affect depression or anxiety symptoms (low strength of evidence), and care integration (by multiple types of health care professionals) did not affect depression symptoms or substance use (low strength of evidence). Providing contraceptive care earlier (compared with later) was associated with greater implant use at 6 months (summary effect size 1.36, 95% CI 1.13–1.64) (moderate strength of evidence). Location of breastfeeding care did not affect hospitalization, other unplanned care utilization, or mental health symptoms (all low strength of evidence). Peer support was associated with higher rates of any or exclusive breastfeeding at 1 month and any breastfeeding at 3–6 months (summary effect size 1.10–1.22) but not other breastfeeding measures (all moderate strength of evidence). Care by a lactation consultant was associated with higher breastfeeding rates at 6 months (summary effect size 1.43, 95% CI 1.07–1.91) but not exclusive breastfeeding (all moderate strength of evidence). Use and nonuse of information technology for breastfeeding care were associated with comparable rates of breastfeeding (moderate strength of evidence). Testing reminders for screening or preventive care were associated with greater adherence to oral glucose tolerance testing but not random glucose or hemoglobin A1c testing (moderate strength of evidence).

CONCLUSION:
Various strategies have been shown to improve some aspects of postpartum care, but future research is needed on the most effective care delivery strategies to improve postpartum health.

SGLT2 Inhibitor-pretreated Macrophage Transplantation Improves Adverse Ventricular Remodeling After Acute Myocardial Infarction
Authors: Chen Rundu , Zhang Yingqian , Zhou Hao , Hu Yingyun , Chen Yundai 
Published: August 2023

Abstract:
Macrophages play an important role in the progression of acute myocardial infarction (AMI). Studies have shown that sodium-dependent glucose transporter 2 inhibitor (SGLT2i) after AMI could increase the proportion of M2 type/M1 macrophages and reduces adverse ventricular remodeling (AVR) post-AMI. This study aimed to investigate whether SGLT2i-pretreated macrophage transplantation could reduce AVR after AMI and the underlying mechanisms. C57BL/6 mice were used to establish an AMI model by ligating the coronary arteries. Dynamic observation of transplanted bone marrow-derived macrophages (BMDMs) was performed using an in vivo imaging system. Cardiac function was assessed using echocardiography. The fibrosis ratio was measured using Masson's trichrome staining. Cardiomyocyte (CM) apoptosis was measured using the TUNEL assay. Macrophage subtypes were measured using flow cytometry. We detected the expression of inflammatory factors in the myocardium and serum using enzyme-linked immunosorbent assay and reverse transcription-polymerase chain reaction. The in vivo imaging system revealed that transplanted SGLT2i-pretreated BMDMs were present in the infarcted myocardium for 7 days. Flow cytometry revealed that SGLT2i-pretreated BMDMs promoted the conversion of native-derived macrophages to the M2 type. SGLT2i-pretreated BMDMs also reduced inflammatory factors (IL-6, TNFα, and IL-1β) in the infarcted myocardium and serum. At 28 days post-AMI, SGLT2i-pretreated BMDMs increased cardiac function and vascular density, but reduced CM hypertrophy. SGLT2i-pretreated BMDMs could reduce CM apoptosis and fibrotic area ratio. In conclusion, transplanted SGLT2i-pretreated BMDMs were present in the infarcted myocardium for 7 days and improved AVR by reducing inflammation and modulating the conversion of native mice-derived macrophages to M2-type macrophages.
