Predicción a largo plazo de la resistencia a cortante de vigas de hormigón armado basada en un modelo mecánico considerando la corrosión de la armadura
Authors: Frontera Alejandro , Cladera Antoni 
Published: February 2024

La corrosión de los cercos, generalmente con un menor diámetro y recubrimiento, afecta significativamente la resistencia a cortante de los elementos de hormigón armado. Puesto que las roturas a cortante pueden provocar colapsos de carácter frágil, es necesario evitarlas durante toda la vida útil de la estructura. El Compresion Chord Capacity Model (CCCM, modelo de capacidad de la cabeza comprimida) es un modelo mecánico que ha sido extendido recientemente para predecir la resistencia a cortante de elementos dañados por los efectos de la corrosión. Este trabajo combina la capacidad del modelo mecánico con los dos modelos de deterioro incluidos en el nuevo Código Estructural para evaluar la resistencia a cortante a largo plazo, permitiendo considerar tanto la corrosión por carbonatación como la inducida por iones cloruro. Finalmente, en el artículo se lleva a cabo un análisis paramétrico para explorar el efecto de los parámetros más influyentes en la degradación de la resistencia a cortante según los modelos utilizados y en función de diferentes clases de exposición.

BackgroundThe COVID-19 pandemic placed great strain on healthcare professionals, leading to a substantial impact and a redistribution of the workforce. Despite the active involvement of the Eastern Mediterranean Region Office (EMRO) and the World Health Organization in managing mental health crises, there is a knowledge gap concerning the working conditions and training opportunities available for early career psychiatrists (ECPs) during the pandemic period.ObjectivesThis study aims to investigate the impact of the COVID-19 pandemic on ECPs and how it affected their well-being, employment, and educational opportunities.MethodsA mixed methods study has been conducted in Iran, Egypt, and Tunisia, three EMRO member countries. It includes a cross-sectional survey with self-reported questions, and a qualitative study with individual in-depth interviews.DiscussionThe findings of this study will raise awareness to the working conditions of ECPs within the EMRO region and its member societies, both during the COVID-19 pandemic and beyond. The results will serve as a basis for encouraging supervisors and policymakers to mitigate the pandemic’s impact on psychiatric training, strengthen healthcare systems’ preparedness, and equip early career psychiatrists with the necessary skills to deal with the mental health consequences of the COVID-19 pandemic.
Corporate Governance as Antecedent of Financial Distress: Case Study of Textile Industry of Pakistan
Authors: Hassan Jamal Ahmed 
Published: February 2024

Purpose: The present research studies the effect of corporate governance practices on the level of financial distress of the Textile companies listed at PSX.
Design/Methodology: Data from 2019 to 2022 from a sample of 43 companies operating in the weaving, spinning and composite textile industry was assessed in the study. Regression analysis was used to predict the impact of board independence, board size, audit committee independence and duality in the role of CEO and chairman on the financial distress.
Findings: The findings reveal that board independence, board size and the duality in the role of Chairman and CEO impacts the financial distress level of the companies and that in companies wherein governance structure is strong, the likelihood of financial distress is lower. However, the effect of Audit committee independence is found to be insignificant in this study.
Originality: This study provides support to the companies in understanding the importance of governance structure and its significance in reducing financial distress level. The findings of the study will be of value to the companies operating in textile sector by enabling them to strengthen their governance structure to address the financial distress situation. Further, this study will help the regulators in drafting the governance requirements for the companies and also educating them about the importance of the latter. In future, other studies using different proxies of corporate governance like gender diversity in the board, number of board meetings and characteristics of audit committee may be conducted..
Coregistration of EEG and eye-tracking in infants and developing populations
Authors: Kulke Louisa 
Published: February 2024

Abstract
Infants cannot be instructed where to look; therefore, infant researchers rely on observation of their participant’s gaze to make inferences about their cognitive processes. They therefore started studying infant attention in the real world from early on. Developmental researchers were early adopters of methods combining observations of gaze and behaviour with electroencephalography (EEG) to study attention and other cognitive functions. However, the direct combination of eye-tracking methods and EEG to test infants is still rare, as it includes specific challenges. The current article reviews the development of co-registration research in infancy. It points out specific challenges of co-registration in infant research and suggests ways to overcome them. It ends with recommendations for implementing the co-registration of EEG and eye-tracking in infant research to maximise the benefits of the two measures and their combination and to orient on Open Science principles while doing so. In summary, this work shows that the co-registration of EEG and eye-tracking in infant research can be beneficial to studying natural and real-world behaviour despite its challenges.
Voluntary task switching is affected by modality compatibility and preparation
Authors: Friedgen Erik , Koch Iring , Poljac Edita , Liefooghe Baptist , Stephan Denise Nadine 
Published: February 2024

AbstractCognitive task control can be examined in task-switching studies. Performance costs in task switches are usually smaller with compatible stimulus-response modality mappings (visual-manual and auditory-vocal) than with incompatible mappings (visual-vocal and auditory-manual). Modality compatibility describes the modality match of sensory input and of the anticipated response effect (e.g., vocal responses produce auditory effects, so that auditory stimuli are modality-compatible with vocal responses). Fintor et al. (Psychological Research, 84(2), 380–388, 2020) found that modality compatibility also biased task choice rates in voluntary task switching (VTS). In that study, in each trial participants were presented with a visual or auditory spatial stimulus and were free to choose the response modality (manual vs. vocal). In this free-choice task, participants showed a bias to create more modality-compatible than -incompatible mappings. In the present study, we assessed the generality of Fintor et al.’s (2020) findings, using verbal rather than spatial stimuli, and more complex tasks, featuring an increased number of stimulus-response alternatives. Experiment 1 replicated the task-choice bias to preferentially create modality-compatible mappings. We also found a bias to repeat the response modality just performed, and a bias to repeat entire stimulus-response modality mappings. In Experiment 2, we manipulated the response-stimulus interval (RSI) to examine whether more time for proactive cognitive control would help resolve modality-specific crosstalk in this free-choice paradigm. Long RSIs led to a decreased response-modality repetition bias and mapping repetition bias, but the modality-compatibility bias was unaffected. Together, the findings suggest that modality-specific priming of response modality influences task choice.
The Orbital Geometries and Stellar Obliquities of Exoplanet-hosting Multistar Systems
Authors: Rice Malena , Gerbig Konstantin , Vanderburg Andrew 
Published: February 2024

Abstract
The current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multistar systems, which may have their evolution shaped by the gravitational influence of bound stellar companions. In this work, we examine the joint distribution of stellar obliquities and orbital orientations for transiting exoplanets residing within astrometrically resolved binary and triple-star systems. We leverage existing constraints on stellar obliquities in exoplanet systems, together with astrometric measurements from Gaia DR3, to uncover a set of fully aligned, “orderly” exoplanet systems that exhibit evidence of both spin–orbit and orbit–orbit alignment. We also find evidence that the observed distribution of orbit–orbit orientations in our sample is more strongly peaked toward alignment than an isotropic distribution. Our results may be indicative of efficient viscous dissipation by nodally recessing protoplanetary disks, demonstrating a regime in which stellar companions produce and maintain order in planetary systems, rather than enhancing misalignments.
Metallicity Distribution in the LMC and the SMC Based on the Tip-RGB Colors
Authors: Li 李 Ying 颖 , Jiang 姜 Biwei 碧沩 , Ren 任 Yi 逸 
Published: February 2024

Abstract
The color index (J − K)0 of tip-red-giant branch (TRGB) is used to study the metallicity distribution in the Large and Small Magellanic Cloud. With the most complete and pure sample of red member stars so far, the areas are divided into 154 and 70 bins for the LMC and SMC, respectively, with similar number of stars by the Voronoi binning. For each bin, the position of TRGB on the near-infrared color–magnitude diagram, specifically (J − K)0/K
0, is determined by the poison-noise weighted method. Converting the color index of TRGB into metallicity, the metallicity gradients in the LMC and the SMC are obtained in four major directions. For the LMC, the gradient to the north is −0.006 ± 0.004 dex kpc−1, to the south −0.010 ± 0.005 dex kpc−1, to the east −0.006 ± 0.003 dex kpc−1, and to the west −0.010 ± 0.003 dex kpc−1. The farthest distance extends to 16 kpc. For the SMC, the gradients to the north, south, east, and west are −0.017 ± 0.031 dex kpc−1, −0.016 ± 0.007 dex kpc−1, −0.003 ± 0.002 dex kpc−1, and −0.004 ± 0.003 dex kpc−1, respectively. The farthest distance for the SMC extends to 27 kpc. The gradient is large from the center to 1 kpc.

Abstract
While the standard X-ray variability of black hole X-ray binaries (BHXBs) is stochastic and noisy, there are two known BHXBs that exhibit exotic “heartbeat”-like variability in their lightcurves: GRS 1915+105 and IGR J17091–3624. In 2022, IGR J17091–3624 went into outburst for the first time in the NICER/NuSTAR era. These exquisite data allow us to simultaneously track the exotic variability and the corresponding spectral features with unprecedented detail. We find that as in typical BHXBs, the outburst began in the hard state, then continued in the intermediate state, but then transitioned to an exotic soft state, where we identify two types of heartbeat-like variability (Class V and a new Class X). The flux energy spectra show a broad iron emission line due to relativistic reflection when there is no exotic variability, and absorption features from highly ionized iron when the source exhibits exotic variability. Whether absorption lines from highly ionized iron are detected in IGR J17091–3624 is not determined by the spectral state alone, but rather is determined by the presence of exotic variability; in a soft spectral state, absorption lines are only detected along with exotic variability. Our finding indicates that IGR J17091–3624 can be seen as a bridge between the most peculiar BHXB GRS 1915+105 and “normal” BHXBs, because it alternates between the conventional and exotic behaviors of BHXBs. We discuss the physical nature of the absorbing material and exotic variability in light of this new legacy data set.
A Comprehensive Comparison of Various Galactic Cosmic-Ray Models to the State-of-the-art Particle and Radiation Measurements

Published: February 2024

Abstract
Galactic cosmic rays (GCRs) are the slowly varying background energetic particles that originate outside the solar system, are modulated by the heliospheric magnetic field, and pose ongoing radiation hazards to deep space exploration missions. To assess the potential radiation risk, various models have been developed to predict the GCR flux near Earth based on propagation theories and/or empirical functions. It is essential to benchmark these models by validating against the state-of-the-art measurements. In this work, a comprehensive model–observation comparison of the energy-dependent particle flux has been performed, by combining five typical GCR models and observational data from the Cosmic Ray Isotope Spectrometer on board the Advanced Composition Explorer spacecraft at relatively lower energies and data from the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics and Alpha Magnetic Spectrometer at higher energies. The analysis shows that, out of the five models investigated in this study, the optimal model, characterized by minimal relative difference or reduced chi-square divergence from measurements, depends on the particle type, energy range, and epoch of interest. Furthermore, a silicon slab is applied to compute the absorbed dose rate using conversion factors applied to GCR model outputs, and the results are compared to measurements from the Cosmic Ray Telescope for the Effects of Radiation. The comparisons in this paper have implications for the strengths and limitations of individual GCR models, advance our comprehension of the underlying GCR transport mechanisms, and also have strong application aspects for mitigating space radiation risks.

Published: February 2024

Abstract
This paper describes the design and development process and details the successfully completed qualification work of an industry-first rotary-shouldered connection that is 20,000 psi working pressure rated as per American Petroleum Institute (API) Standard 17G[1]. This connection is used in a Drill Pipe-Based Riser (DPBR) that can be used in a Through-BOP Intervention Riser System (TBIRS)[1] or in an Open Water Intervention Riser System (OWIRS)[1]. The design and qualification of the connection while navigating the different challenging requirements from several industry standards are described, along with valuable lessons learned.
Failures Modes Effects and Criticality Analysis (FMECA) was performed using a collaborative process between various stakeholders and used to create a detailed qualification program. Finite Element Analysis (FEA) was used to determine the static, functional and cyclic capacities of the threaded connector in accordance with API 17G[1], API 17TR8[2] and ASME Boiler and Pressure Vessel Code (B&PVC) Section VIII Division 3[5]. Physical testing consisted of validating the connector capacities by performing make- and-break (functionality) testing, sealability testing, and cyclic fatigue testing. Independent Third Party (I3P) witnessing, and review was completed on all relevant design and qualification activities as per the Bureau of Safety and Environmental Enforcement (BSEE) requirements for High Pressure High Temperature (HPHT) equipment.
The drill pipe type connection used to complete this fit-for-purpose design and subsequent API 17G qualification for a 20,000 psi riser is a versatile product that reduces the total cost of ownership. It enhances operational efficiencies in offshore completion, intervention, and workover activities, allowing for multiple trips without repair. After successful completion of the qualification program, the product improves endurance capacities without compromising pressure sealability.
Case Study - Improvements to Cementing Operation and Installation of Cement Packer and Inflatable Cement Retainer for Water Shut-Off

Published: February 2024

Abstract
This paper highlights the related challenges, lessons learned, and recommended best practices to improve the cementing operation and installation of cement packer and inflatable cement retainer using Coiled Tubing (CT) as conveyance during zonal isolation operations for meeting the objective of Water Shut-Off (WSO). The study was triggered by a cement overshot issue during a Production Enhancement (PE) job to reactivate Well X-1. The scope of the paper focuses on four (4) aspects - cement design, cementing operational planning, cementing operation execution, and cement verification.
Well X-1, initially completed as a single gas producer from A1/A2 sand in 1997, underwent subsequent isolation of A1/A2 sand using a tubing plug and additional perforation at B1/B2 sand in 2002. A workover was performed in 2010 to replace tubing size and reperforate B1/B2 sand. However, sand production led to the well being idle in 2014. To reactivate Well X-1, a Non-Routine Production Enhancement (NR-PE) job was performed, involving a Water Shut-Off (WSO) using cement to prevent unwanted water production and later installing Thru-Tubing Gravel Pack (TTGP) as the remedial sand control. However, the job was suspended due to cement overshot during WSO operation that covered the entire H1 interval after 3 stages of cement pumping (i.e. after severe cement loss into formation during the 1st & 2nd stages of cement pumping). A Root Cause and Failure Analysis (RCFA) was conducted, where best practices and lessons learned were documented.
The Post Job Analysis and Lessons Learned Report (PJALLR) revealed three (3) main issues - cementing overshot, difficulties during the setting of the Retrievable Cement Packer (RCP) and the unsuccessful setting of the Permanent Inflatable Bridge Plug Cement Retainer (PIBP-CR).

Abstract
Carbon and GHG emission reduction targets are becoming ubiquitous in the oil and gas industry, with most producing companies having defined and published ambitious objectives for the next decades.
In reality, there is still limited feedback and knowledge of practical and sustainable carbon reduction solutions, outside of a small number of players.
This paper aims to present an efficient, semi-qualitative methodology to define decarbonization road maps, help Energy Producers to fill this knowledge gap and enables organization to take a more holistic and strategic approach to meet their environmental commitment.
The methodology developed leverages on proven Concept Identification and Selection tools and methodology, decades of experience in energy efficiency improvement, CO2 capture and a deep understanding of the oil and gas technologies and practices. It has been enhanced with Carbon footprint assessment tools, and an innovative way to visualize the economic and environmental impacts of Carbon reduction opportunities, to support investment decision and road map definition.
This methodology also allows to test different scenarios against various sets of legislative, operational, and economic constraints aligned with the possible future strategies of the organization. It helps decision-makers to explore the potential impacts of different CO2 reduction strategies, and identify which ones are most likely to succeed in achieving their goals.
To illustrate the efficiency and outcome produced with the described methodology, case studies will be presented.
