Vejez y enfermedad en 'Como caracol...' de Alaíde Ventura Medina
Authors: Flores Grajales María Guadalupe 
Published: February 2025

Alaíde Ventura Medina (Xalapa, 1985), en su primera novela, Como caracol... –premio Gran Angular 2018–, explora el reencuentro de una niña con su abuela, que enfrenta un estado de transición hacia el alzhéimer. Mediante el relato de la enfermedad, la autora liga el pasado y el presente afectivo, corporal y simbólico. La pérdida de memoria de la abuela conlleva una pérdida de autoestima y de identidad, y deteriora el estado físico y emocional de la familia. No obstante, la autocompasión y la desacreditación social son sustituidas por la propuesta digna de la abuela ante la vejez, la enfermedad y la muerte. La necesidad de depender del otro, el deterioro físico debido a la enfermedad y la pérdida de memoria, que trae como consecuencia el temor ante la ausencia de autonomía, hacen del individuo un sujeto frágil y vulnerable psíquica y socialmente. Pero el Alzheimer también permite que la historia familiar se construya y deconstruya: se develan secretos, ausencias y rencores. Así, la presencia de la enfermedad da paso a una nueva forma de convivencia, identificada como del afecto (Pons y Guerrero, 2018) ante la vejez y la enfermedad, en conjunción con el desgaste físico y emocional.

Abstract
Wafer-level direct bonding has become a critical process for advanced 3D architectures in logic, memory, and CMOS image sensors. The minimization of the wafer distortion caused by wafer bonding is essential for a precise overlay for the subsequent backside lithography. Although numerous studies have reported a strong connection between distortion and bond wave speed, discussion of the relationship between the pre-bonding surface and the bond wave speed has been inadequate. This study aimed to clarify the latter correlation using 300 mm wafers. Through the application of surface-sensitive techniques, we found that the plasma activation process enhances the amount of Si–OH groups on the surface, thereby enhancing the bond wave speed. Conversely, high-power plasma results in a slight decrease in bond wave speed because of the influence of excessive adsorbed water. In addition, the present study reveals no correlation between bond wave speed and adherence energy.

Lansia mengharapkan kehidupan yang tenang dan damai, tetapi tidak semua mendapatkannya. Perubahan fisik dan mental serta kurangnya adaptasi terhadap stres dapat menyebabkan depresi. Terapi tertawa merupakan intervensi non-farmakologis yang dapat membantu menurunkan tingkat depresi dengan meningkatkan ekspresi kebahagiaan dan mengurangi stres. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan pemahaman dan keterampilan lansia dalam menerapkan terapi tertawa. Dilaksanakan di wilayah kerja Puskesmas Kecamatan Makasar, kegiatan ini melibatkan 20 lansia dengan pendekatan quasi-eksperimental menggunakan desain pre-test dan post-test tanpa kelompok kontrol. Intervensi dilakukan dalam bentuk edukasi dan praktik terapi tertawa selama tiga minggu dengan frekuensi satu kali per minggu. Pengukuran tingkat depresi menggunakan Geriatric Depression Scale (GDS) sebelum dan sesudah intervensi. Hasil analisis menunjukkan penurunan skor GDS 80% yang mengindikasikan berkurangnya tingkat depresi. Secara kualitatif, peserta melaporkan peningkatan suasana hati, rasa kebersamaan, dan motivasi untuk bersosialisasi. Kesimpulan dari kegiatan ini adalah terapi tertawa efektif dalam menurunkan depresi pada lansia dan perlu dikembangkan sebagai bagian dari program kesehatan mental komunitas.

Elderly individuals aspire to live a peaceful and serene life, but not all of them achieve this. Physical and mental changes, along with a lack of adaptation to stress, can lead to depression. Laughter therapy is a non-pharmacological intervention that can help reduce depression levels by enhancing expressions of happiness and reducing stress. This community service activity aims to improve the understanding and skills of the elderly in applying laughter therapy. Conducted in the working area of the Makasar District Public Health Center, this activity involved 20 elderly participants using a quasi-experimental approach with a pre-test and post-test design without a control group. The intervention was carried out in the form of education and laughter therapy practice over three weeks, with a frequency of once per week. Depression levels were measured using the Geriatric Depression Scale (GDS) before and after the intervention. The analysis results showed an 80% reduction in GDS scores, indicating a decrease in depression levels. Qualitatively, participants reported an improvement in mood, a sense of togetherness, and increased motivation to socialize. In conclusion, laughter therapy is effective in reducing depression among the elderly and should be developed as part of community mental health programs.

Perkawinan dini menjadi salah satu penyebab perceraian yang paling dominan di Indonesia. Hal ini tentunya perlu menjadi perhatian yang serius karena dapat berdampak pada kualitas generasi penerus di masa depan. Berdasarkan hal tersebut, maka kami tertarik untuk melakukan pencegahan terjadinya perkawinan dini dengan edukasi kepada masyarakat, yaitu melalui penyuluhan hukum yang kami laksanakan di SMAN 42 Jakarta. Menurut Kepala Sekolah SMAN 42 Jakarta yaitu bapak Deden Suhendi, belum pernah ada yang melakukan sosialiasi terkait upaya pencegahan perkawinan dini. Sehingga ini menjadi suatu kesempatan yang baik bagi kami untuk melaksanakan sosialisasi di SMAN 42 Jakarta. Metode yang digunakan dalam kegiatan ini adalah dengan menggunakan metode ceramah, yaitu melalui pemberian materi terkait UU Perkawinan, selain itu juga diberikan pre-test dan post-test untuk mengukur pemahaman siswa tentang materi yang diberikan. Hasil kegiatan ini menunjukkan bahwa berdasarkan perbandingan antara pre-test dan post-test, terdapat kenaikan signifikan terhadap jawaban siswa yang benar terkait materi perkawinan dini. Para peserta memahami materi yang disampaikan, narasumber menguasai materi. Secara keseluruhan, kegiatan ini sukses dalam mencapai tujuan edukasi dan dapat dijadikan sebagai model untuk program pengabdian masyarakat lainnya.

Early marriage is one of the most dominant causes of divorce in Indonesia. This certainly needs serious attention because it can affect the quality of the next generation in the future. Based on this, we are interested in preventing early marriage by educating the community, namely through legal counseling that we carry out at SMAN 42 Jakarta. According to the Principal of SMAN 42 Jakarta, Mr. Deden Suhendi, no one has ever conducted socialization related to efforts to prevent early marriage. So this is a good opportunity for us to carry out socialization at SMAN 42 Jakarta. The method used in this activity is to use the lecture method, namely by providing material related to the Marriage Law, in addition to a pre-test and post-test to measure students' understanding of the material given. The results of this activity show that based on the comparison between the pre-test and post-test, there is a significant increase in students' correct answers related to the material on early marriage. The participants understand the material presented, the resource person masters the material. Overall, this activity was successful in achieving educational goals and can be used as a model for other community service programs.

The Membership and Age of the Planet-hosting Young Star IRAS 04125+2902*
Authors: Luhman K. L. 
Published: February 2025

Abstract
A transiting planet was recently discovered around a star in the Taurus star-forming region, IRAS 04125+2902, making it one of the youngest known planets. The discovery paper cited two age estimates for IRAS 04125+2902, one based on a comparison to two sets of model isochrones in the Hertzsprung–Russell diagram and a second age reported by an earlier study for a putative population in Taurus that includes IRAS 04125+2902 (D4-North). However, the model isochrones in question differ significantly for most temperatures and luminosities of young low-mass stars, and do not reproduce the observed sequences for the TW Hya and 32 Ori associations (10 and 21 Myr). Meanwhile, as found in my previous work, D4-North is a collection of field stars and fragments of several distinct Taurus groups and older associations, so its quoted age is not meaningful. The true parent population for IRAS 04125+2902 is a small group that is ∼35 pc behind the L1495 and B209 clouds (B209N). I have analyzed the age of B209N through a comparison to TW Hya and 32 Ori. The M-star sequences in the latter two associations have the same shapes, but the sequence for B209N is flatter, indicating that >M4 stars at ages of <10 Myr fade more quickly than stars at earlier types and older ages. For the one member of B209N that is earlier than M4 (IRAS 04125+2902), I estimate an age of 3.0 ± 0.4 Myr based on its offsets from TW Hya and 32 Ori, which by happenstance is similar to the value derived through the comparison to model isochrones.
Long-term X-Ray Variability on the Benchmark YSO HL Tau

Published: February 2025

Abstract
HL Tau is one of the most well-studied Class I young stellar objects (YSOs), including frequent observations at near- and mid-infrared, (sub)millimeter, and X-ray wavelengths. We present the results of an X-ray variability monitoring campaign with XMM-Newton in 2020 and X-ray grating spectroscopy from Chandra/HETGS in 2018. We find that the X-ray spectrum of HL Tau is consistently hot (with characteristic plasma temperatures T ≳ 30 MK) over 31 epochs spanning 20 yr, which is consistent in temperature with most Class I YSOs. The high-resolution HETG spectrum indicates the presence of some cooler plasma. We characterize the variability of the star across the 31 observations and find a subset of observations with significant variability on a ∼21-day timescale in the observed count rate and flux. We discuss the possible origins of this variability and identify further observations that would better constrain the nature of the changes.
Empirical Constraints on Tidal Dissipation in Exoplanet Host Stars
Authors: Millholland Sarah C. , MacLeod Morgan , Xiao Felicia 
Published: February 2025

Abstract
The orbits of short-period exoplanets are sculpted by tidal dissipation. However, the mechanisms and associated efficiencies of these tidal interactions are poorly constrained. We present robust constraints on the tidal quality factors of short-period exoplanetary host stars through the usage of a novel empirical technique. The method is based on analyzing structures in the population-level distribution of tidal decay times, defined as the time remaining before a planet spirals into its host star due to stellar tides. Using simple synthetic planet population simulations and analytic theory, we show that there exists a steady-state portion of the decay time distribution with an approximately power-law form. This steady-state feature is clearly evident in the decay time distribution of the observed short-period planet population. We use this to constrain both the magnitude and frequency dependence of the stellar tidal quality factor and show that it must decrease sharply with planetary orbital period. Specifically, with

Published: February 2025

Abstract
The 2024 May 10 space weather event stands out as the most powerful storm recorded during the current solar cycle. This study employs a numerical framework utilizing a semiempirical coronal model, along with heliospheric upwind extrapolation with time dependence and cone coronal mass ejection (CME) models for the inner heliosphere, to forecast solar wind velocity and the arrival of CMEs associated with this event. The simulations were also carried out using the Space Weather Adaptive Simulation framework and a drag-based model (DBM) for this complex event of multiple CMEs. Predicted arrival times and velocities from these models are compared with actual observations at the Sun–Earth L1 point. These simulations reveal that three CMEs reached Earth nearly simultaneously, resulting in the extreme space weather event, followed by the arrival of a few more eruptions. The simulations accurately predicted arrival times with a discrepancy of approximately 5 hr or less for these CMEs. Further, the ensemble study of the DBM shows the sensitivity of the CME arrival time to the background solar wind speed and drag parameters. All three models have done fairly well in reproducing the arrival time closely to the actual observation of the CMEs responsible for the extreme geomagnetic storm of 2024 May 10. These rare solar storms offered a unique opportunity to thoroughly evaluate and validate our advanced models for predicting their arrival at Earth.
Dynamic Photometric Variability in Three Young Brown Dwarfs in Taurus: Detection of Optical Flares with TESS Data

Published: February 2025

Abstract
We present I-band time-series photometric variability studies of three known nearby (∼140 pc) and young (∼1 Myr) brown dwarfs (BD) in the Taurus star-forming region in the Perseus molecular cloud. From 10 nights of observations over a time span of 10 yr, with a typical run of 3–6 hr each night, we estimated that the BDs show unstable short-scale periodicity from 1.5 to 4.8 hr. Using the long-term photometry from the Transiting Exoplanet Survey Satellite (TESS), we have conducted a time-resolved variability analysis of CFHT-BD-Tau 3 and CFHT-BD-Tau 4, revealing orbital periods of ∼0.96 days and ∼3 days respectively, consistent with earlier studies. We also found two superflares in TESS sector 43 data for CFHT-BD-Tau 4 and estimated the flare energies as 7.09 × 1035 erg and 3.75 × 1036 erg. A magnetic field of ∼3.39 kG is required to generate such flare energies on this BD. We performed spot modeling analysis on CFHT-BD-Tau 3 and CFHT-BD-Tau 4 to address the variability detected in the data using the package BASSMAN. Spectral energy distribution and infrared colors of the sources suggest that they have a sufficient amount of circumstellar material around them.

Abstract
We report the large scale structure and clustering analysis of Lyα emitters (LAEs) and Lyα blobs (LABs) at z = 2.2–2.3. Using 3341 LAEs, 117 LABs, and 58 bright (Lyα luminosity L
Lyα
> 1043.4 erg s−1) LABs at z = 2.2–2.3 selected with Subaru/Hyper Suprime-Cam, we calculate the LAE overdensity to investigate the large scale structure at z = 2. We show that 79% of LABs and 83% of bright LABs are located in overdense regions, which is consistent with the trend found by previous studies that LABs are generally located in overdense regions. We find that one of our eight fields, dubbed J1349, contains 39/117 ≈ 33% of our LABs and 22/58 ≈ 38% of our bright LABs. A unique and overdense

(40 × 20 comoving Mpc2) region (J1347 protocluster) has 12 LABs (eight bright LABs). By comparing to SSA22, which is one of the most overdense LAB regions found by previous studies, we show that the J1347 protocluster region has a higher bright LAB density than the SSA22 protocluster region with a 1σ significance. We calculate the angular correlation functions (ACFs) of LAEs and LABs in the unique J1349 field and fit the ACFs with a power-law function to measure the slopes. The bright LABs show a 5σ larger slope, suggesting that bright LABs are more clustered than faint LAEs. Our LABs have a large galaxy bias of ∼5–7, which suggests that LABs generally reside in more massive dark matter halos (halo masses M ≳ 1013
M
⊙) than faint LAEs.
