AbstractWith the advancement of industrial low carbonization and electrification, emerging industrial production technologies have the characteristics of high‐power consumption and significant impact load. In the context of increasing global climate change, frequent extreme weather events have brought serious challenges to the balance of power and electricity in the power system, and have a significant impact on the production scheduling of industrial users, especially industrial users using electrified production technology. First, based on the representative high‐power industrial users of hydrogen reduction steel plants and internet datacentres (IDC), this paper establishes a flexible resource scheduling optimization model for single industrial users, and considers the collaborative relationship between multi‐user flexible resources to establish a collaborative scheduling optimization model for industrial users. Then, considering the charging and discharging characteristics of electric vehicles (EV) in extreme scenarios, the redundant capacity of EVs is aggregated by EV aggregators and sold to industrial users, and a collaborative scheduling optimization model of EV aggregators and industrial users is established. Finally, the effectiveness of the proposed model and algorithm is verified by simulation analysis. Compared with the traditional industrial user production optimization, the proposed model can tap the potential of multi‐agent scheduling operation in extreme scenarios.
Transient synchronization stability mechanism of PMSG with additional inertia control
Authors: Zhang Yayao , Zhan Meng 
Published: October 2024

AbstractSynchronous stability is crucial for the safety and operation of AC power systems. However, most of the current researches focused on the stability of grid‐connected converters, and that of renewable equipment still lacked. In this article, the impact of the additional inertia control (AIC) on the permanent magnet synchronous generator (PMSG) is studied. It is found that with the AIC, the machine‐side converter dynamics of the PMSG cannot be ignored, and the system dominant dynamics shifts from the electromagnetic to electromechanical timescales. This article develops a simplified model for the single‐PMSG infinite‐bus system with the AIC within the electromechanical timescale, and reveals the transient synchronization stability mechanism from three aspects: the machine‐network interface, transient dominant variable, and interaction between the synchronization loop and the power imbalance loop. Finally, this article analyzes the swing characteristics of the PMSG system, and uncovers the relationship between the energy transmission and synchronization. These findings are supported by wide experimental verification and can provide the deeper physical insight and theoretical basis for the transient synchronous stability analysis of renewable‐dominated new‐type power systems.

Published: October 2024

Context. The appearance of the jets and lobes of some radio galaxies makes it difficult to assign them to a known class of objects. This is often due to the activity of the central engine and/or interactions with the environment, as well as projection effects.
Aims. We analyse the radio data for an apparently asymmetric radio source 4C 70.19, which is associated with the giant elliptical galaxy NGC 6048. The source shows distorted radio jets and lobes, one of which bends by 180°. The aim of our study is to explain the nature of the observed distortions.
Methods. We used LOFAR, Effelsberg, and VLA radio data in a wide range of frequencies. At high frequencies, we also used radio polarimetry to study the properties of the magnetic fields. Additionally, we made use of optical, infra-red, and X-ray data.
Results. Polarisation data suggest shearing of the magnetic fields at points where the jets bend. The low-frequency LOFAR map at 145 MHz, as well as the sensitive single-dish Effelsberg map at 8.35 GHz, reveal previously undetected diffuse emission around the source. The rotation measure (RM) derived from the polarimetric data allowed us to estimate the density of the medium surrounding the source, which agrees with typical densities of the intergalactic medium or the outer parts of insterstellar halos.
Conclusions. We propose that the southern jet is bent in the same manner as the northern one, but that it is inclined to the sky plane. Both these bends are likely caused by the orbital motion within the galaxy group, as well as interactions with the intergalactic medium. Our analyses suggest that, despite its complex morphology, 4C 70.19 seems to be intrinsically symmetric with a physical extent of up to 600 kpc, and that the diffuse emission detected in our high-sensitivity maps is related to radio plumes that are expanding behind the source.
Flows, circulations, and energy transport in the outer and deep atmospheres of synchronous and non-synchronous hot Jupiters
Authors: Sainsbury-Martinez Félix , Tremblin Pascal 
Published: October 2024

Aims. Recent studies have shown that vertical enthalpy transport can explain the inflated radii of highly irradiated gaseous exoplanets. Simultaneously, they have also shown that rotation can influence this transport, leading to highly irradiated, rapidly rotating objects that are uninflated. Here, we explore the flows that underpin this transport, including the impact of synchronous or non-synchronous rotation.
Methods. We used DYNAMICO to run a series of long timescale HD209458b-like atmospheric models at various rotation rates. For models that are tidally locked, we considered rotation rates between 1/16th and 40 times the rotation rate of HD209458b, whilst for non-synchronous models, we considered the range one-eighth to four times HD209458b.
Results. We find that our synchronous models fall into one of three Ω-dependent regimes. At low Ω, we find that the outer atmosphere dynamics are driven by a divergent day-night wind, which drives weak vertical transport and can lead to the formation of a night-side hot-spot. At intermediate Ω, we find classical hot Jupiter dynamics, whilst at high Ω we find a strong Coriolis effect that suppresses off-equator dynamics, including the jet-driving standing waves, thus also reducing vertical transport. As for non-synchronicity, when small, we find that it has little effect on the dynamics. However as it grows, we find that temporal variations prevent the formation of the persistent structures that drive large-scale dynamics and transport.
Conclusions. We find that rotation can significantly impact the atmospheric dynamics of irradiated exoplanets, including vertical enthalpy advection, which may help explain the scatter in the hot Jupiter radius-irradiation relation. We have also identified a seemingly robust atmospheric feature at slow rotation: a night-side hot-spot. As this may have important implications for both the phase curve and atmospheric chemistry, we suggest that this study be followed up with next-generation global circulation models (GCMs) that robustly model radiation and chemistry.
Estimates of (convective core) masses, radii, and relative ages for ∼14 000 Gaia-discovered gravity-mode pulsators monitored by TESS
Authors: Mombarg Joey S. G. , Aerts Conny , Van Reeth Timothy , Hey Daniel 
Published: October 2024

Context. Gravito-inertial asteroseismology saw its birth from the 4-year-long light curves of rotating main-sequence stars assembled by the Kepler space telescope. High-precision measurements of internal rotation and mixing are available for about 600 stars of intermediate mass so far that are used to challenge the state-of-the-art stellar structure and evolution models.
Aims. Our aim is to prepare for future large ensemble modelling of gravity-mode pulsators by relying on a new sample of such stars recently discovered from the third Data Release of the Gaia space mission and confirmed by space photometry from the TESS mission. This sample of potential asteroseismic targets is about 23 times larger than the Kepler sample.
Methods. We use the effective temperature and luminosity inferred from Gaia to deduce evolutionary masses, convective core masses, radii, and ages for ∼14 000 gravity-mode pulsators classified as such from their nominal TESS light curves. We do so by constructing two dedicated grids of evolutionary models for rotating stars with input physics from the asteroseismic calibrations of Keplerγ Dor pulsators. These two grids consider the distribution of initial rotation velocities at the zero-age main sequence deduced from gravito-inertial asteroseismology, for two extreme values found for the metallicity of γ Dor stars deduced from spectroscopy ([M/H]=0.0 and −0.5).
Results. We find the new gravity-mode pulsators to cover an extended observational instability region covering masses from about 1.3 M⊙ to about 9 M⊙. We provide their mass-luminosity and mass-radius relations, as well as convective core masses. Our results suggest that oscillations excited by the opacity mechanism occur uninterruptedly for the mass range above about 2 M⊙, where stars have a radiative envelope aside from thin convection zones in their excitation layers.
Conclusions. Our evolutionary parameters for the sample of Gaia-discovered gravity-mode pulsators with confirmed modes by TESS offer a fruitful starting point for future TESS ensemble asteroseismology once a sufficient number of modes is identified in terms of the geometrical wave numbers and overtone for each of the pulsators.
The tight correlation between PAH and CO emission from z ∼ 0 to 4
Authors: Shivaei Irene , Boogaard Leindert A. 
Published: October 2024

Aims. The cold molecular gas mass is one of the crucial, yet challenging, parameters in galaxy evolution studies. Here, we introduce a new calibration and a method for estimating molecular gas masses using mid-infrared (MIR) photometry. This topic is timely as the James Webb Space Telescope (JWST) now allows us to detect the MIR emission of typical main-sequence galaxies across a wide range of masses and star formation rates with modest time investments. Additionally, this Letter highlights the strong synergy between ALMA and JWST for studies of dust and gas at cosmic noon.
Methods. We combined a sample of 14 main-sequence galaxies at z = 1 − 3 with robust CO detections and multi-band MIR photometry, along with a literature sample at z = 0 − 4 with CO and polycyclic aromatic hydrocarbon (PAH) spectroscopy, to study the relationship between PAH, CO(1–0), and total IR luminosities. PAH luminosities are derived by modelling a wealth of rest-frame UV to sub-millimetre data. The new z = 1 − 3 sample extends previous high-z studies to PAH and CO luminosities that are about an order of magnitude lower, into the regime of local starbursts, for the first time.
Results. The PAH-to-CO luminosity ratio remains constant across a wide range of luminosities, for various galaxy types, and throughout the explored redshift range. In contrast, the PAH-to-IR and CO-to-IR luminosity ratios deviate from a constant value at high IR luminosities. The intrinsic scatter in the L(PAH)–L′(CO) relation is 0.21 dex, with a median of 1.40 and a power-law slope of 1.07 ± 0.04. Both the PAH–IR and CO–IR relations are sub-linear. Given the tight and uniform PAH–CO relation over ∼3 orders of magnitude, we provide a recipe for estimating the cold molecular gas mass of galaxies from PAH luminosities, with a PAH-to-molecular gas conversion factor of αPAH7.7 = (3.08 ± 1.08)(4.3/αCO) M⊙/L⊙. This method opens a new window to explore the gas content of galaxies beyond the local Universe using multi-wavelength JWST/MIRI imaging.

Authors: Jahn Claus 
Published: October 2024

SummaryGanglien, auch Synovialzysten genannt, entstehen durch Flüssigkeitsaustritt aus der Gelenkkapsel, wodurch sich eine Pseudozyste („Überbein“) bildet. Zu den möglichen Ursachen zählen Traumen, Entzündungen, Überlastungen oder Degeneration im Gelenkbereich. Im vorgestellten Fall entwickelte eine Berufsmusikerin durch ständige mechanische Belastung ein Ganglion im Bereich des Handgelenkes mit Schmerzen und Bewegungseinschränkungen. Konventionelle Therapien wie Ruhigstellung, Antiphlogistika, Punktion oder Chirurgie waren aufgrund ihres Berufs nicht möglich oder blieben erfolglos. Eine Kombination aus naturheilkundlicher Schmerzreduktion, Ableitung des Zysteninhaltes, Stärkung des Bindegewebes und Ordnungstherapie stellte die Schmerzfreiheit und Beweglichkeit so weit her, dass die Patientin ihren Beruf wieder problemlos ausführen konnte.

Synthesis and Characterization of Acacia-Stabilized
Doxorubicin-Loaded Gold Nanoparticles for Breast Cancer Therapy
Authors: Devi Laxmi , Kushwaha Poonam , Ansari Tarique Mahmood , Rao Amit , Kumar Ashish 
Published: October 2024

AbstractThe targeted delivery of drugs is vital in breast cancer treatment due to its
ability to produce long-lasting therapeutic effects with minimal side effects.
This study reports the successful development of doxorubicin hydrochloride
(DOX)-loaded colloidal gold nanoparticles stabilized with acacia gum (AG).
Optimization studies varied AG concentrations (0.25% to 3% w/v) to determine
optimal conditions for nanoparticle synthesis. The resulting acacia stabilized
gold nanoparticles (AGNPs) were characterized using various techniques including
high-resolution transmission electron microscopy (HR-TEM), powder X-ray
diffraction (PXRD), differential scanning calorimetry (DSC), ultraviolet-visible
spectroscopy, Fourier-transform infrared spectroscopy (FT-IR), field emission
scanning electron microscopy (FE-SEM), and selected area electron diffraction
(SAED). In vitro drug release studies demonstrated a higher release rate of DOX
in sodium acetate buffer (pH 5.0) compared to phosphate buffer saline (pH 7.4),
suggesting an enhanced therapeutic efficacy in acidic tumor environments.
Cytotoxicity of DOX-AGNPs and free DOX was assessed in human breast cancer cells
(MDA-MB-231). The DOX-AGNPs exhibited significantly greater cytotoxicity,
indicating enhanced efficacy in targeting cancer cells. This enhancement
suggests that adsorbing DOX on the surface of gold nanoparticles can improve
drug delivery and effectiveness, potentially reducing side effects compared to
pure DOX and traditional delivery methods. Stability tests conducted over six
months at 25±1°C showed significant changes in particle size and PDI, suggesting
limited stability under these conditions. Overall, the acacia-stabilized gold
nanoparticles synthesized in this study exhibit promising characteristics for
drug delivery applications, particularly in cancer therapy, with effective drug
loading, controlled release, and favorable physicochemical properties.

Published: October 2024

Abstract
Introduction Surgery for skull base epidermoid cysts (SBECs) has several inherent risks including aseptic meningitis and cerebrospinal fluid (CSF) malabsorption. Perioperative measures to reduce the likelihood of such complications have not been evaluated, and this study sought to compare outcomes before and after implementation of an institutional perioperative protocol in the management of SBECs.
Methods Review of a prospective database of surgically managed SBECs. Outcomes were compared before (2003–2008) and after (2010–2021) implementation of a perioperative protocol including intraoperative hyper-irrigation, prolonged course of postoperative steroids, and aggressive management of CSF malabsorption.
Results A total of 39 patients were included: 12 before and 27 after implementation of the protocol. The groups were similar with respect to mean age (p = 0.99), gender (p = 0.29), surgical approach—most commonly retrosigmoid (p > 0.99)—and extent of resection—most commonly total or near total (p = 0.64). The post-protocol implementation group had a significantly lower rate of CSF diversion (p = 0.04). The overall rates of hydrocephalus (7 vs. 30%), CSF leak (19 vs. 33%), bacterial meningitis (15 vs. 33%), and mean length of stay (12 vs. 49 days) were lower in the post-implementation group, although differences did not reach statistical significance. Rates of aseptic meningitis and cranial nerve palsies were similar.
Conclusion Our additional perioperative measures resulted in more favorable CSF dynamics with reduced need for CSF diversion and secondary consequences such as wound leaks and infective meningitis.

Abstract
Objective Transnasal skull base surgery is a complex and invasive procedure that involves the use of preoperative antiseptic preparations. However, evidence supporting their use in preventing postoperative infectious complications is limited. The aim of this study is to assess the efficacy of preoperative antiseptic techniques in reducing postoperative infectious complications within 30 days of surgery.
Methods A multicenter, prospective, randomized, single-blind, three-arm trial was conducted from February 2019 to October 2021. Participants were randomized to either of three antiseptic preparation techniques: external 0.9% NaCl nasal preparation, external 0.05% chlorhexidine gluconate, or intranasal irrigation with 80 mg of gentamicin added to 1,000 mL of 0.9% NaCl plus external nasal preparation with chlorhexidine gluconate 0.05%. A total of 130 adults with skull base pathologies were randomized; 12 were excluded before randomization for failure to meet the inclusion criteria (n = 9) or refusal to participate (n = 3). We excluded patients with evidence of infection adjacent to the surgical site, allergies to preparation methods, those who underwent craniotomy during the same admission, and pediatric patients.
Results The mean age of the participants was 43.26 ± 14.45 years. Nine patients developed postoperative infections (meningitis, n = 8; sinusitis, n = 2). Among the factors studied, length of surgery (p = 0.002), perioperative cerebrospinal fluid (CSF) diversion (p = 0.01), chordoma (p = 0.004), extended approach (p = 0.026), and postoperative CSF leak (p = 0.025) were significantly associated with postoperative infections. There were no clinically meaningful or significant differences in the studied intervention groups regarding postoperative infectious complications.
Conclusion Preoperative antiseptic techniques failed to prefer one application to prevent postoperative infectious complications in patients who underwent endoscopic transnasal skull base surgery.

Published: October 2024

AbstractOut of 42 naturally occurring monosaccharides, only seven are abundant in Nature (glucose, galactose, mannose, fructose, xylose, ribose, and l-arabinose), while the others have been classified as ‘rare sugars’. Fungi and bacteria use a wide range of monosaccharides, in contrast to mammals, reflected in their glycosylated metabolites, as well as the cellular machineries that are involved in their sugar metabolism. Recognition of the microbiome’s impact on human health has led to increased interest in microbial glycans, as they often mediate interaction between host and microbes. Efficient access to rare sugars and oligosaccharides is necessary to study their roles in Nature, which can provide new pharmacological leads. Furthermore, it enables the synthesis of bioactive glycosylated natural products and congeners. This short review highlights recent progress in the synthesis and the efficient, site- and stereoselective glycosylation of rare sugars. Finally, it provides a recent example where synthetic access to rare sugars has enabled biochemical studies to better understand and interfere with processes in Nature.1	Introduction2	Synthesis of Rare Sugars2.1	Syntheses from Renewable Feedstock2.2	De Novo Syntheses3	Glycosylation3.1	Catalyst-Controlled Glycosylation3.2	One-Pot Iterative Oligosaccharide Synthesis in Solution4	Application in Biochemical Research5	Conclusion
