Abstract
We present the first results of an extensive spectroscopic survey of directly imaged planet host stars. The goal of the survey is the measurement of stellar properties and abundances of 15 elements (including C, O, and S) in these stars. In this work, we present the analysis procedure and the results for an initial set of five host stars, including some very well-known systems. We obtain C/O ratios using a combination of spectral modeling and equivalent-width measurements for all five stars. Our analysis indicates solar C/O ratios for HR 8799 (0.59 ± 0.11), 51 Eri (0.54 ± 0.14), HD 984 (0.63 ± 0.14), and GJ 504 (0.54 ± 0.14). However, we find a supersolar C/O (0.81 ± 0.14) for HD 206893 through spectral modeling. The ratios obtained using the equivalent-width method agree with those obtained using spectral modeling but have higher uncertainties (∼0.3 dex). We also calculate the C/S and O/S ratios, which will help us to better constrain planet formation, especially once planetary sulfur abundances are measured using JWST. Finally, we find no evidence of highly elevated metallicities or abundances for any of our targets, suggesting that a super metal-rich environment is not a prerequisite for large, widely separated gas planet formation. The measurement of elemental abundances beyond carbon and oxygen also provides access to additional abundance ratios, such as Mg/Si, which could aid in further modeling of their giant companions.

Abstract
Full-disk measurements of the solar magnetic field by the Helioseismic and Magnetic Imager (HMI) are often used for magnetic field extrapolations, but its limited spatial and spectral resolution can lead to significant errors. We compare HMI data with observations of NOAA 12104 by the Hinode Spectropolarimeter (SP) to derive a scaling curve for the magnetic field strength, B. The SP data in the Fe i lines at 630 nm were inverted with the SIR code. We find that the Milne–Eddington inversion of HMI underestimates B and the line-of-sight flux, Φ, in all granulation surroundings by an average factor of 4.5 in plage and 9.2 in the quiet Sun in comparison to the SP. The deviation is inversely proportional to the magnetic fill factor, f, in the SP results. We derived a correction curve to match the HMI B with the effective flux B
f in the SP data that scaled HMI B up by 1.3 on average. A comparison of non-force-free field extrapolations over a larger field of view without and with the correction revealed minor changes in connectivity and a proportional scaling of electric currents and Lorentz force (∝B ∼ 1.3) and free energy (∝B
2 ∼ 2). Magnetic field extrapolations of HMI vector data with large areas of plage and quiet Sun will underestimate the photospheric magnetic field strength by a factor of 5–10 and the coronal magnetic flux by at least a factor of 2. An HMI inversion including a fill factor would mitigate the problem.
Prospects for Observing High-redshift Radio-loud Quasars in the SKA Era: Paving the Way for 21 cm Forest Observations
Authors: Niu Qi , Li Yichao , Xu Yidong , Guo Hong , Zhang Xin 
Published: January 2025

Abstract
The 21 cm forest is a sensitive probe for the early heating process and small-scale structures during the epoch of reionization (EOR), to be realized with the upcoming Square Kilometre Array (SKA). Its detection relies on the availability of radio-bright background sources, among which the radio-loud quasars are very promising, but their abundance during the EOR is still poorly constrained due to limited observations. In this work, we use a physics-driven model to forecast future radio-loud quasar observations. We fit the parameters of the model using observational data of high-redshift quasars. Assuming Eddington accretion, the model yields an average lifetime of t
q ~ 105.5 yr for quasars at z ~ 6, consistent with recent results obtained from quasar proximity zone observation. We show that if the radio-loud fraction of quasars evolves with redshift, it will significantly reduce the abundance of observable radio-loud quasars in the SKA era, making 21 cm forest studies challenging. With a constant radio-loud fraction, our model suggests that a 1 yr sky survey conducted with SKA-LOW has the capability to detect approximately 20 radio-loud quasars at z ~ 9, with sufficient sensitivity to resolve individual 21 cm forest lines.

Published: January 2025

Abstract
Building a comprehensive catalog of galaxy clusters is a fundamental task for studies on structure formation and galaxy evolution. In this paper, we present Cluster Optical Search using Machine Intelligence in Catalogs (COSMIC), an algorithm utilizing machine learning techniques to efficiently detect galaxy clusters. COSMIC involves two steps, the identification of the brightest cluster galaxies and the estimation of cluster richness. We train our models on galaxy data from the Sloan Digital Sky Survey and the WHL galaxy cluster catalog. Validated against test data in the region of the northern Galactic cap, the COSMIC algorithm demonstrates high completeness when crossmatching with previous cluster catalogs. Richness comparison with previous optical and X-ray measurements also demonstrates a tight correlation. Our methodology showcases robust performance in galaxy cluster detection and holds promising prospects for applications in upcoming large-scale surveys.

Abstract
We report the detection of repeated transits in the TESS light curves of TYC 8996-1013-1 (TIC 414929408) with a period of 2.77542 ± 0.00001 days and a width of 4.32 hr. We did not find significant variability in the transit time through the observations taken during TESS Sectors 37, 38, 64 and 65. The color B − V and the GAIA DR3 spectrum of TYC 8996-1013-1 point to a stellar temperature of ≈5000 K and radius of ≈1 R
⊙, and thus the transit model suggests a Neptune size for the candidate transiting planet (radius ≈ 25,000 km).
Pytaxon: A Python software for resolving and correcting taxonomic names in biodiversity data
Authors: Proença Neto Marco , De Sousa Marcos 
Published: January 2025

The standardisation and correction of taxonomic names in large biodiversity databases remain persistent challenges for researchers, as errors in species names can compromise ecological analyses, land-use planning and conservation efforts, particularly when inaccurate data are shared on global biodiversity portals.
We present pytaxon, a Python software designed to resolve and correct taxonomic names in biodiversity data by leveraging the Global Names Verifier (GNV) API and employing fuzzy matching techniques to suggest corrections for discrepancies and nomenclatural inconsistencies. The pytaxon offers both a Command Line Interface (CLI) and a Graphical User Interface (GUI), ensuring accessibility to users with different levels of computing expertise. Tests on spreadsheets derived from datasets published in the Global Biodiversity Information Facility (GBIF) demonstrated its effectiveness in identifying and resolving taxonomic errors. By mitigating the propagation of inaccuracies from researchers' datasets to global biodiversity databases, pytaxon supports more reliable conservation decisions and robust scientific investigations. Its contributions enhance data integrity and promote informed biodiversity management in a rapidly evolving global environment.

Authors: Wang Yanhong , Zhang Ke , Ruan Haihui , Niu Xiaodan , Zhang Jing , Chen Yaxin , Tao Hongxia 
Published: January 2025

Purpose

To report the prevalence and risk factors of elder self-neglect (ESN) among community-dwelling older adults (
N
= 604).

Method
The current cross-sectional study was conducted from July 2019 to October 2020 in Lanzhou City, China. ESN was determined by the Scale of Elderly Self-Neglect, which evaluates five dimensions: (a) medical health and care, (b) environmental sanitation and personal hygiene, (c) mental health, (d) safety, and (e) social engagement. Frailty was assessed using the Physical Frailty Phenotype scale. Participants were asked whether they had bothersome and activity-limiting pain over the past 1 month. Characteristics associated with ESN were identified through multiple linear regression analyses.

Results

Mean age of participants was 71.34 years (
SD
= 7.15 years), and 255 (57.8%) were female. The prevalence of ESN among participants was 16.2%. Among the five dimensions of ESN, medical health and care accounted for the largest proportion (44%). Approximately 58% of participants were pre-frail and 11.4% were frail, and 45% reported experiencing bothersome pain. Older adults with a household monthly income per capita <2,000 RMB (β = −0.112,
p
< 0.05), larger waist circumference (β = 0.185,
p
< 0.001), pre-frailty (β = 0.176,
p
< 0.001), frailty (β = 0.420,
p
< 0.001), and pain (β = 0.102,
p
< 0.05) were more prone to ESN.

Conclusion

ESN is a prevalent issue among community-dwelling older adults. Frailty, pain, low economic status, and larger waist circumference are identified as independent risk factors for ESN. There is a need to improve the understanding of ESN among health care providers and policymakers. Personalized interventions aimed at preventing or addressing these risk factors may lead to improvements in ESN outcomes. [

Published: January 2025

Purpose
Stroke family caregivers often struggle to provide care. The purpose of the current study was to determine: (a) ease or difficulty with caregiving tasks; (b) life changes because of providing care; and (c) relationship between caregiving tasks and life changes.

Method
A descriptive correlational design was used. Telephone interviews were conducted with 74 stroke caregivers. Tasks were measured using the Oberst Caregiving Burden Scale; life changes with the Bakas Caregiving Outcomes Scale.

Results

The most difficult tasks were managing survivor behaviors and the most negative life changes were lack of time for social activities. The easiest tasks were medical or nursing treatments, whereas the most positive life change was an improved relationship with the survivor. Tasks and life changes were different for each caregiver. Caregiver tasks and life changes were moderately correlated (
r
= 0.33,
p
< 0.01).

Conclusion

Caregiver tasks and life changes are important for designing strategies to support stroke caregivers. [

Una innovación estadística: las encuestas 1-2-3
Authors: Razafindrakoto Mireille 
Published: January 2025

En el centro de las cuestiones de desarrollo, la economía informal ha sido durante mucho tiempo una terra incognita. Sin embargo, desempeña un papel decisivo en los países del Sur, ya que es la principal fuente de ingresos de la inmensa mayoría de los hogares, sobre todo de los más pobres. En estos países, la inmensa mayoría de los empleos se encuentran en la economía informal. Habida cuenta de lo que está en juego, el método de encuesta 1-2-3 ha permitido responder a un doble desafío, estadístico y económico: medir aquello que se escapa de la medición - la economía informal - y comprender su funcionamiento y su dinámica. Esta metodología fue desarrollada y consolidada por el IRD a través de diversos proyectos nacionales y regionales lanzados a principios de los años 90 y realizados en estrecha colaboración con los institutos nacionales de estadística, en asociación con centros de investigación y universidades, organismos regionales, agencias y donantes. Este estudio repasa los trabajos realizados en tres países: Perú, Madagascar y Vietnam. Describe cómo los resultados de la investigación han generado impactos en los ámbitos social, económico, institucional, político, académico y de capacitación.
Innovative PVD Technology Solutions for Advanced Substrate, EMI Shielding, and Backside Metal
Authors: Turner Jeff 
Published: January 2025

Traditional silicon scaling with Moore’s law is facing fundamental technical and cost challenges. Several IDM and foundry customers are utilizing heterogenous integration and system in package approaches to meet next generation performance and cost requirements. A number of integration scheme approaches for SiP (System in Package) implementation are being developed. Each of these approaches poses challenges that require innovative technical solutions. 5G, AI, and HPC devices are driving this adoption of Heterogeneous Integration (HI). HI uses various packaging technologies to integrate different functional chips in side-by-side or die stack formats from different fabless design houses, foundries, wafer sizes, and feature sizes into a system. For the next few decades, we will see the trend of a higher level of HI, whether it is for time-to-market, performance, form factor, power consumption, signal integrity, or cost savings. One example to be covered of how the industry is working to accomplish these market trends and requirements, is by the deposition of metal layers using PVD on the backside of wafers for thermal dissipation purposes. This is especially critical for the high thermal dissipation requirements for power devices such as SiC, GaN, and IGBT. In this presentation, we will review new PVD processes and flows to improve the performance of packages while lowering the cost structure of 5G, AI, and HPC devices. Applied Materials offers various PVD solutions to meet those requirements, such as panel sputtering processing, backside metal deposition and EMI shielding.
Fan Out Wafer Level Package With Enhanced Product Reliability and Advanced Node Silicon Chip Package Integration

Published: January 2025

Different fan out wafer level package (FOWLP) versions are used in the industry for various device applications in hand held consumer products. Traditional wafer level fan out is a die first, die down FOWLP that has been in volume production for low end baseband, PMIC, Codec, Wi-Fi, RF products. A die up high-density fan out package process has found adoption for mobile phone processor and DRAM integration in a package on package format. For all these applications the primary product package benefits are small form factor, reduced height and better electrical, thermal performance. All these advantages are the result of absence of substrate between the die and printed circuit board (PCB), which leads to reduced package size and shorter electrical signal and thermal conduction path. However, when the package is directly mounted on PCB, then board level temperature cycling may lead to significant coefficient of thermal expansion (CTE) mismatch between the package and PCB in some instances. This CTE mismatch may stress the package solder joint leading to cyclic fatigue related solder joint cracking. Stiffer solder alloys have been evaluated to minimize the fatigue damage due to cyclic stress and thus improve the solder joint fatigue life. However, the higher stiffness of the solder alloy may move the induced cyclic stress and failure from the solder joint to the package metal interconnect. Moreover, wafer level packages for advanced silicon nodes may have fragile low-k and extremely low-k back end of line dielectric layers that can also crack or delaminate in cyclic fatigue. In this work several design of experiment legs including different package interconnect layer stack ups, dielectric materials, solder alloys, were mechanically modelled and empirically tested to achieve optimum package design that passed the following product reliability qualification conditions - high temperature storage life (150°C, 2000 hours), application level temperature cycling ((-40 °C to 125 °C, 600 cycles), board level temperature cycling (-40 °C to 125 °C, 500 cycles) and board level drop test (1500g/0.5ms, 30 drops). Excellent product reliability performance and successful chip package integration for all levels of interconnects (silicon-package- board) was achieved.
Achieving Success in Automotive Leadframe Packages
Authors: Nickelsen John 
Published: January 2025

In recent years, the quality and reliability requirements of the automotive market have increased significantly. Among other things, automotive customers are demanding zero defects and zero delamination after extended reliability testing. To support these market requirements,Amkor has invested and continues to invest substantial resources in two strategic directions. The first strategic direction is the development of automation tools to significantly reduce escaped defects and achieve zero delamination. Defect trapping/isolation has been improved by marking tracking identification on leadframe strips prior to the start of assembly. The tracking marks are then used to create defect maps when automatic optical inspection (AOI) is performed following wire bonding and again during open and short (O/S) electrical testing after the completion of assembly. In addition to preventing defective parts from escaping, these automatic inspections provide rapid feedback to the process engineering team in the factory. In the case of the defects caught at AOI, there is a photographic record of all defects found that the engineering team can use to troubleshoot the issue without the need for further failure analysis. As a part of the plan for extending automation implementation for the automotive market, Amkor is currently developing support for Die Traceability Systems (DTS) for leadframe products. DTS leverages the equipment and processes put in place to support defect trapping with the addition of the integration of the die attach equipment with the strip mark tracking to link the customer electronic wafer map to leadframe strip maps. This creates a record of which die are placed on which leadframe locations. The unit laser markers near the end of the assembly process then mark a 2D code on the package identifying the package and linking it to the information about the die and wafer as well as the defect maps generated during the assembly process. The DTS records will be electronically transferred to customers as needed. The second strategic direction has been the development of the capability for leadframe packages to consistently achieve zero delamination following extended automotive reliability (AEC Q100 & Q006 G1 & G0) testing. Many different combinations of processes and materials were tried before consistent results were achieved. With the initial success of these efforts, further implementation is occurring across the broad portfolio of leadframe packages. This success has been achieved by focusing on many factors including design, process and environmental controls, and the interactions of physical properties of the bill of materials (BOM) elements. This paper discusses these strategic directions in greater detail.
The Effects of the Global Pandemic on Women Athletic Training Students as They Transitioned to Practice
Authors: Kloepfer Marlaina E. , Gardiner-Shires Alison M. , Duckett Emily A. , Wood Heather N. 
Published: January 2025

Context
The transition to practice process is complex and facilitated by many formal and informal processes. The coronavirus disease 2019 global pandemic presented unique challenges for athletic trainers. An identity-specific focus is necessary to understand better the transition to practice process during the pandemic.

Objective
To understand (1) what socializing factors influence a cohort of women athletic trainers who graduated from the same professional master’s (PM) athletic training program as they transitioned to practice and (2) the unique challenges the women athletic trainers faced as they sought employment and transitioned into their first professional roles during the pandemic.

Design
Qualitative phenomenological cohort study.

Setting
Semistructured, in-depth, 1-on-1 videoconference interviews.

Patients or other Participants
Six women (24.83 ± .96 years old) who graduated from the same PM athletic training program now working in various athletic training settings.

Data Collection and Analysis
We conducted semistructured interviews via Zoom (Zoom Video Communications). Interviews were transcribed, and a general phenomenological approach to analysis was used. Member checks, multiple analyst triangulation, and peer review were used to ensure trustworthiness.

Results
Three main themes emerged that describe the effects of the pandemic on the transition to practice of women athletic trainers: (1) personal identity, (2) relational identity, and (3) professional identity. Several subthemes were also identified to further illustrate the participants’ lived experiences.

Conclusions
Although some of the participants’ socialization and transition to practice experiences were similar to other graduates described in the literature, the personal, relational, and professional identities of these women athletic trainers were influenced by the pandemic. The participants purposefully sought women mentors to assist them with navigating the challenges of developing a professional identity during the pandemic. There is a need to create gender-specific networks to support individuals during their growth from novice to professional.
