Key Points

There is a well-established score for predicting contrast-associated AKI (CA-AKI) after coronary angiography, but there remains a paucity of data regarding its prediction after contrast-enhanced computed tomography (CT).CA-AKI after contrast-enhanced CT risk factors are male sex, admission setting, hemoglobin <10 g/dl, and eGFR.Pre-CT AKI score, using these factors, predicts CA-AKI risk with an area under the receiver operating characteristic curve of 0.715 and 0.706 for external validation.

Background
The lack of a recognized risk evaluation for contrast-associated AKI (CA-AKI) after contrast-enhanced computed tomography (CECT) makes it challenging to counsel patients before the procedure. This study aims to identify the incidence of CA-AKI after CECT, assess the associated risk factors, and develop and validate a predictive score.

Methods
All adult patients who underwent CECT in 2018–2022 were included in the training cohort, whereas those in 2023 formed the external validation cohort. Exclusions applied to patients with CKD stage 5, recent dialysis, or incomplete data. Multiple logistic regression was used to identify risk factors. The area under the receiver operating characteristic curve was used to evaluate both internal and external validation.

Results
From 21,878 enrolled patients, 6042 and 2463 met the inclusion criteria for the training and validation cohorts with a mean eGFR of 86.0 (26.4) and 81.4 (27.6) ml/min per 1.73 m2, respectively. In the training cohort, 492 patients (8.1%) developed CA-AKI, and 49 (0.8%) required dialysis. Independent risk factors of CA-AKI included male sex, clinical setting, hemoglobin levels of <10 g/dl, and baseline eGFR <90 ml/min per 1.73 m2. The model, using a weighted integer score derived from these factors, exhibited an area under the receiver operating characteristic curve of 0.715 (95% confidence interval, 0.692 to 0.743) in the training cohort and 0.706 (95% confidence interval, 0.663 to 0.748) in the validation cohort.

Conclusions
CECT can lead to CA-AKI in specific populations. The pre-computed tomography AKI risk score for CA-AKI after CECT demonstrated good discriminative power and can be easily applied in clinical practice.

Prospects on Agricultural Development in Kuwait, An Overview
Authors: Omar Asem Samira 
Published: October 2024

High Gross Domestic Product (GDP) countries in the Arabian Peninsula, such as the State of Kuwait, invest billions of dollars annually for developing the agricultural sector to counter harsh climatic conditions, poor soil fertility, and scarcity of irrigation water. With the increase in population, these countries must increase agricultural production to meet rising demands and reduce reliance on food imports, which currently constitute about 90% of the total food demand in Kuwait. This study provides an overview of the agricultural sector in Kuwait to assess the current status of agricultural development and provide recommendations for improvement, considering key factors such as economic constraints, climate change and food security. An intensive literature review was carried out with an assessment of available data at local institutions. Despite the challenges over the past two decades, agricultural areas have been expanding by 38%. The number of holdings increased by 300% in 2017/18. Large subsidies are granted by the government amounting to KD 26 million in 2019/20. However, the agricultural sector’s contribution to GDP did not exceed 0.6% over the past decade with little indication of a significant growth trend in the future. To enhance local food production, Kuwait must adopt sustainable agricultural technologies and reduce the demand on land reclamation for irrigation purposes. The future outlook of the agricultural sector, however, is not clear under the current business as usual. Strategic planning for resilient agricultural development may consider sustainable farming technology systems with renewable energy, such as vertical and smart farming systems. This will boost agricultural production for social sustainability and environmental benefits such as reducing the demand on land, water, electricity, and chemical usage. Future research is needed to assess the economic sustainability of large-scale advanced technology farming systems considering climate change, energy demand and food security.

El objetivo de la investigación es presentar a la comunidad científica una nueva forma de ejecutar la terapia a pacientes con neoplasia, utilizando la neurorrehabilitación y las nuevas tecnologías. Neoplasia se utiliza en el área de la medicina para determinar al crecimiento anómalo de un tejido, formado por un conjunto de células que se esparcen a un ritmo superior al normal. Se dividen en benignas y malignas, la primera significa que no evoluciona en otros espacios, mientras que la segunda se disemina ejecutando metástasis. La etiología de la neoplasia puede ser multifactorial y compleja. El diagnóstico de tumores cerebrales es un proceso complejo que combina la evaluación clínica, técnicas de imagen avanzadas, biopsias, y análisis moleculares para determinar la presencia, localización, tipo, y características de un tumor cerebral. El diagnóstico comienza con una entrevista clínica donde se recogen los antecedentes médicos del paciente, incluyendo cualquier síntoma neurológico, historial familiar de cáncer, y posibles factores de riesgo como exposición a radiación o sustancias químicas. El trabajo posee un enfoque cualitativo, mientras que su diseño es no experimental y descriptivo. Es analítico, descriptivo y bibliográfico. Se emplea la técnica del análisis - sistemático. Se inicia con aportes inductivas hasta concluir con situaciones globales.

Abstract
We present the third catalog release of the wide-area (31.3 deg2) Stripe 82 X-ray survey. This catalog combines previously published X-ray source properties with multiwavelength counterparts and photometric redshifts, presents 343 new spectroscopic redshifts, and provides black hole masses for 1297 Type 1 active galactic nuclei (AGN). With spectroscopic redshifts for 3457 out of 6181 Stripe 82X sources, the survey has a spectroscopic completeness of 56%. This completeness rises to 90% when considering the contiguous portions of the Stripe 82X survey with homogeneous X-ray coverage at an optical magnitude limit of r < 22. Within that portion of the survey, 23% of AGN can be considered obscured by being either a Type 2 AGN, reddened (R − K > 4, Vega), or X-ray obscured with a column density of N
H > 1022 cm−2. Unlike other surveys, there is only an 18% overlap between Type 2 and X-ray obscured AGN. We calculated black hole masses for Type 1 AGN that have Sloan Digital Sky Survey spectra using virial mass estimators calibrated on the Hβ, Mg ii, Hα, and C iv emission lines. We find wide scatter in these black hole mass estimates, indicating that statistical analyses should use black hole masses calculated from the same formula to minimize bias. We find that the AGN with the highest X-ray luminosities are accreting at the highest Eddington ratios, consistent with the picture that most black hole mass accretion happens in the phase when the AGN is luminous (L
2−10keV > 1045 erg s−1).
A Model for Eruptive Mass Loss in Massive Stars

Published: October 2024

Abstract
Eruptive mass loss in massive stars is known to occur, but the mechanism(s) are not yet well understood. One proposed physical explanation appeals to opacity-driven super-Eddington luminosities in stellar envelopes. Here, we present a 1D model for eruptive mass loss and implement this model in the MESA stellar evolution code. The model identifies regions in the star where the energy associated with a local super-Eddington luminosity exceeds the binding energy of the overlaying envelope. The material above such regions is ejected from the star. Stars with initial masses of 10−100 M
⊙ at solar and SMC metallicities are evolved through core helium burning, with and without this new eruptive mass-loss scheme. We find that eruptive mass loss of up to ∼10−2
M
⊙yr−1 can be driven by this mechanism, and occurs in a vertical band on the H-R diagram between

. This predicted eruptive mass loss prevents stars of initial masses ≳20 M
⊙ from evolving to become red supergiants (RSGs), with the stars instead ending their lives as blue supergiants, and offers a possible explanation for the observed lack of RSGs in that mass regime.
Constraining the Origin of the Nanohertz Gravitational-wave Background by Pulsar Timing Array Observations of Both the Background and Individual Supermassive Binary Black Holes
Authors: Chen Yunfeng , Yu Qingjuan , Lu Youjun 
Published: October 2024

Abstract
The gravitational waves (GWs) from supermassive binary black holes (BBHs) have long been sought by pulsar timing array (PTA) experiments, in the forms of both a stochastic GW background (GWB) and individual sources. Evidence for a GWB was reported recently by several PTAs with origins to be determined. Here we use a BBH population synthesis model to investigate the detection probability of individual BBHs by the Chinese PTA (CPTA) and the constraint on the GWB origin that may be obtained by PTA observations of both GWB and individual BBHs. If the detected GWB signal is entirely due to BBHs, a significantly positive redshift evolution (∝ (1 + z)2.07) of the mass scaling relation between supermassive black holes and their host galaxies is required. In this case, we find that the detection probability of individual BBHs is ∼85% or 64% if using a period of 3.4 yr of CPTA observation data, with an expectation of ∼1.9 or 1.0 BBHs detectable with a signal-to-noise ratio ≥3 or 5, and it is expected to increase to >95% if the observation period is extended to 5 yr or longer. Even if the contribution from BBHs to the GWB power signal is as small as ∼10%, a positive detection of individual BBHs can still be expected within an observation period of ∼10 yr. A nondetection of individual BBHs within several years from now jointly with the detected GWB signal can put a strong constraint on the upper limit of the BBH contribution to the GWB signal and help identify/falsify a cosmological origin.
Next-generation Accretion Disk Reflection Model: High-density Plasma Effects

Published: October 2024

Abstract
Luminous accretion disks around black holes are expected to have densities of ∼1015−1022 cm−3, which are high enough that plasma physics effects become important. Many of these effects have been traditionally neglected in the calculation of atomic parameters, and therefore in photoionization models and ultimately also in X-ray reflection models. In this paper, we describe updates to the atomic rates used by the xstar code, which is in turn part of the xillver disk reflection model. We discuss the effect of adding necessary high-density corrections into the xillver code. Specifically, we find that the change of recombination rates plays an important role, dominating the differences between model versions. With synthetic spectra, we show that, even in a highly ionized state, high-density slabs can produce strong iron (∼6.5–9 keV) and oxygen (∼0.6–0.8 keV) resonance features. The significant iron emission could address the problem of the supersolar iron abundances found in some sources.

Abstract
We expect luminous (M
1450 ≲ −26.5) high-redshift quasars to trace the highest-density peaks in the early Universe. Here, we present observations of four z ≳ 6 quasar fields using JWST/NIRCam in the imaging and wide-field slitless spectroscopy mode and report a wide range in the number of detected [O iii]-emitting galaxies in the quasars’ environments, ranging between a density enhancement of δ ≈ 65 within a 2 cMpc radius—one of the largest protoclusters during the Epoch of Reionization discovered to date—to a density contrast consistent with zero, indicating the presence of a UV-luminous quasar in a region comparable to the average density of the Universe. By measuring the two-point cross-correlation function of quasars and their surrounding galaxies, as well as the galaxy autocorrelation function, we infer a correlation length of quasars at 〈z〉 = 6.25 of

Abstract
Bombardment by solar wind ions is one of the main drivers of space weathering on airless bodies. Here, we simulate the solar-wind-driven spectral alteration of loosely packed olivine powders by irradiation with 1.2 keV helium ions (He+). We measured the reflectance spectra of the olivine powder in the ultraviolet–visible–near-infrared (UV–Vis–NIR) wavelength range (0.2–2 μm) as a function of ion fluence. In the Vis–NIR range, we observed spectral darkening, absorption band shallowing, and spectral reddening, in agreement with lunar-style space weathering and previous laboratory studies. In the UV–Vis, spectral darkening was also observed. However, a spectral bluing took place at wavelengths below 400 nm. As the simulated space weathering progressed, the spectral slopes shifted from steep-UV/shallow-NIR slopes to shallow-UV/steep-NIR slopes. Moreover, the change in the UV slope was almost 10 times larger than in the NIR, supporting the hypothesis that the UV spectral slope could be an earlier indicator of space weathering.
