We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG-1216, KMT-2019-BLG-2783, OGLE-2019-BLG-0249, and OGLE-2019-BLG-0679 (planets), as well as OGLE-2019-BLG-0344 and KMT-2019-BLG-0304 (possible planets). The five planets have mean log mass ratio measurements of (−2.6, −3.6, −2.5, −2.2, −2.3), median mass estimates of (1.81, 0.094, 1.16, 7.12, 3.34) M
Jup, and median distance estimates of (6.7, 2.7, 5.9, 6.4, 5.6) kpc, respectively. The main scientific interest of these planets is that they complete the AnomalyFinder sample for 2019, which has a total of 25 planets that are likely to enter the statistical sample. We find statistical consistency with the previously published 33 planets from the 2018 AnomalyFinder analysis according to an ensemble of five tests. Of the 58 planets from 2018–2019, 23 were newly discovered by AnomalyFinder. Within statistical precision, half of the planets have caustic crossings, while half do not; an equal number of detected planets result from major- and minor-image light-curve perturbations; and an equal number come from KMT prime fields versus subprime fields.

The circumgalactic medium (CGM) is often assumed to exist in or near hydrostatic equilibrium, with the regulation of accretion and the effects of feedback treated as perturbations to a stable balance between gravity and thermal pressure. We investigate global hydrostatic equilibrium in the CGM using four highly resolved L
* galaxies from the Figuring Out Gas & Galaxies in Enzo (FOGGIE) project. The FOGGIE simulations were specifically targeted at fine spatial and mass resolution in the CGM (Δx ≲ 1 kpc h
−1 and M ≃ 200M
⊙). We develop a new analysis framework that calculates the forces provided by thermal pressure gradients, turbulent pressure gradients, ram pressure gradients of large-scale radial bulk flows, centrifugal rotation, and gravity acting on the gas in the CGM. Thermal and turbulent pressure gradients vary strongly on scales of ≲5 kpc throughout the CGM. Thermal pressure gradients provide the main supporting force only beyond ∼0.25R
200, or ∼50 kpc at z = 0. Within ∼0.25R
200, turbulent pressure gradients and rotational support provide stronger forces than thermal pressure. More generally, we find that global equilibrium models are neither appropriate nor predictive for the small scales probed by absorption line observations of the CGM. Local conditions generally cannot be derived by assuming a global equilibrium, but an emergent global equilibrium balancing radially inward and outward forces is obtained when averaging over the nonequilibrium local conditions on large scales in space and time. Approximate hydrostatic equilibrium holds only at large distances from galaxies, even when averaging out small-scale variations.
The Surprising Evolution of the Shadow on the TW Hya Disk*

Published: May 2023

We report new total-intensity visible-light high-contrast imaging of the TW Hya disk taken with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope. This represents the first published images of the disk with STIS since 2016, when a moving shadow on the disk surface was reported. We continue to see the shadow moving in a counterclockwise fashion, but in these new images the shadow has evolved into two separate shadows, implying a change in behavior for the occulting structure. Based on radiative-transfer models of optically thick disk structures casting shadows, we infer that a plausible explanation for the change is that there are now two misaligned components of the inner disk. The first of these disks is located between 5 and 6 au with an inclination of 5.5° and position angle (PA) of 170°, and the second between 6 and 7 au with an inclination of 7° and PA of 50°. Finally, we speculate on the implications of the new shadow structure and determine that additional observations are needed to disentangle the nature of TW Hya’s inner-disk architecture.
Interpretation of the Observed Neutrino Emission from Three Tidal Disruption Events

days after the maximum of the optical-ultraviolet (OUV) luminosity. We discuss unified fully time-dependent interpretations of the neutrino signals where the neutrino delays are not a statistical effect, but rather the consequence of a physical scale of the post-disruption system. Noting that X-ray flares and infrared (IR) dust echoes have been observed in all cases, we consider three models in which quasi-isotropic neutrino emission is due to the interactions of accelerated protons of moderate, medium, and ultra-high energies with X-rays, OUV, and IR photons, respectively. We find that the neutrino time delays can be well described in the X-ray model assuming magnetic confinement of protons in a calorimetric approach if the unobscured X-ray luminosity is roughly constant over time, and in the IR model, where the delay is directly correlated with the time evolution of the echo luminosity (for which a model is developed here). The OUV model exhibits the highest neutrino production efficiency. In all three models, the highest neutrino fluence is predicted for AT2019aalc, due to its high estimated supermassive black hole mass and low redshift. All models result in diffuse neutrino fluxes that are consistent with observations.

Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems requires ever larger samples, which can be difficult (even impossible) to select from individual surveys. We use the new platform ESA Datalabs to assemble a catalog of interacting galaxies from the Hubble Space Telescope science archives; this catalog is larger than previously published catalogs by nearly an order of magnitude. In particular, we apply the Zoobot convolutional neural network directly to the entire public archive of HST F814W images and make probabilistic interaction predictions for 126 million sources from the Hubble Source Catalog. We employ a combination of automated visual representation and visual analysis to identify a clean sample of 21,926 interacting galaxy systems, mostly with z < 1. Sixty-five percent of these systems have no previous references in either the NASA Extragalactic Database or Simbad. In the process of removing contamination, we also discover many other objects of interest, such as gravitational lenses, edge-on protoplanetary disks, and “backlit” overlapping galaxies. We briefly investigate the basic properties of this sample, and we make our catalog publicly available for use by the community. In addition to providing a new catalog of scientifically interesting objects imaged by HST, this work also demonstrates the power of the ESA Datalabs tool to facilitate substantial archival analysis without placing a high computational or storage burden on the end user.
HOPS 361-C’s Jet Decelerating and Precessing through NGC 2071 IR

Published: May 2023

We present a two-epoch Hubble Space Telescope study of NGC 2071 IR highlighting HOPS 361-C, a protostar producing an arced 0.2 parsec-scale jet. The proper motions for the brightest knots decrease from 350 to 100 km s−1 with increasing distance from the source. The [Fe ii] and Paβ emission line intensity ratio gives a velocity jump through each knot of 40–50 km s−1. A new [O i] 63 μm spectrum, taken with the German REciever for Astronomy at Terahertz frequencies instrument aboard Stratospheric Observatory for Infrared Astronomy, shows a low line-of-sight velocity indicative of high jet inclination. Proper motions and jump velocities then estimate 3D flow speed for knots. Subsequently, we model knot positions and speeds with a precessing jet that decelerates. The measurements are matched with a precession period of 1000–3000 yr and half opening angle of 15°. The [Fe ii] 1.26-to-1.64 μm line intensity ratio determines visual extinction to each knot from 5 to 30 mag. Relative to ∼14 mag of extinction through the cloud from C18O emission maps, the jet is embedded at a 1/5–4/5 fractional cloud depth. Our model suggests the jet is dissipated over a 0.2 pc arc. This short distance may result from the jet sweeping through a wide angle, allowing the cloud time to fill cavities opened by the jet. Precessing jets contrast with nearly unidirectional protostellar jets that puncture host clouds and can propagate significantly farther.
Search for Extremely Metal-poor Stars with Gemini-N/Graces. I. Chemical-abundance Analysis

Published: May 2023

We present stellar parameters and abundances of 13 elements for 18 very metal-poor (VMP; [Fe/H] < –2.0) stars, selected as extremely metal-poor (EMP; [Fe/H] < –3.0) candidates from the Sloan Digital Sky Survey and Large sky Area Multi-Object Fiber Spectroscopic Telescope survey. High-resolution spectroscopic observations were performed using GEMINI-N/GRACES. We find 10 EMP stars among our candidates, and we newly identify three carbon-enhanced metal-poor stars with [Ba/Fe] < 0. Although chemical abundances of our VMP/EMP stars generally follow the overall trend of other Galactic halo stars, there are a few exceptions. One Na-rich star ([Na/Fe] = +1.14) with low [Mg/Fe] suggests a possible chemical connection with second-generation stars in a globular cluster. The progenitor of an extremely Na-poor star ([Na/Fe] = –1.02) with high K- and Ni-abundance ratios may have undergone a distinct nucleosynthesis episode, associated with core-collapse supernovae (SNe) having a high explosion energy. We have also found a Mg-rich star ([Mg/Fe] = +0.73) with slightly enhanced Na and extremely low [Ba/Fe], indicating that its origin is not associated with neutron-capture events. On the other hand, the origin of the lowest Mg abundance ([Mg/Fe] = –0.61) star could be explained by accretion from a dwarf galaxy, or formation in a gas cloud largely polluted by SNe Ia. We have also explored the progenitor masses of our EMP stars by comparing their chemical-abundance patterns with those predicted by Population III SNe models, and find a mass range of 10–26 M
⊙, suggesting that such stars were primarily responsible for the chemical enrichment of the early Milky Way.

New evidence based on Cassini magnetic field and plasma data has revealed that the discovery of Titan outside Saturn’s magnetosphere during the T96 flyby on 2013 December 1 was the result of the impact of two consecutive interplanetary coronal mass ejections (ICMEs) that left the Sun in 2013 early November and interacted with the moon and the planet. We study the dynamic evolution of Saturn's magnetopause and bow shock, which evidences a magnetospheric compression from late November 28 to December 4 (at least), under prevailing solar wind dynamic pressures of 0.16–0.3 nPa. During this interval, transient disturbances associated with the two ICMEs are observed, allowing for the identification of their magnetic structures. By analyzing the magnetic field direction, and the pressure balance in Titan’s induced magnetosphere, we show that Cassini finds Saturn’s moon embedded in the second ICME after being swept by its interplanetary shock and amid a shower of solar energetic particles that may have caused dramatic changes in the moon’s lower ionosphere. Analyzing a list of Saturn's bow shock crossings during 2004–2016, we find that the magnetospheric compression needed for Titan to be in the supersonic solar wind can be generally associated with the presence of an ICME or a corotating interaction region. This leads to the conclusion that Titan would rarely face the pristine solar wind, but would rather interact with transient solar structures under extreme space weather conditions.

Authors: Limijadi Edward Kurnia Setiawan , Ramadhani Inge Cahya , Hartutiningtyas Dian Tunjungsari , Brajadenta Gara Samara
Published: May 2023

Background: SARS-CoV-2 virus infection is a pandemic that began to emerge in December 2019 in various countries with high death rates of 4-9% until now. In March 2020, Indonesia found its first case where the condition of the infection kept spreading to various regions in Indonesia. Different regional conditions in Indonesia make it difficult to manage this virus infection. The capability of the regional hospitals to detect this virus infection with their facilities and infrastructure is required.
Case presentation: A 17-year-old man came to the Ajibarang Regional Hospital with complaints of coughs and colds felt for four days and fever for two days. Physical examination found a good general condition, moderate pain, the temperature of 38.8°C, pharyngeal hyperemia, and minimal lung crackles sound. Laboratory tests showed normal leukocytes, platelet, and hemoglobin levels. Chest radiograph was suggestive of bronchitis. The patient was hospitalized for approximately four days until the fever resolved and was discharged. Five days after the patient was discharged from the hospital, the results of the viral load examination using RT-PCR confirmed positive for COVID-19.
Conclusion: This case showed unusual conditions of a mild clinical COVID-19 infection, laboratory results that did not support viral infections, as well as radiology examination of only bronchitis. The viral load test was found to be positive. Therefore, the diagnosis of the COVID-19 infection requires a comprehensive interpretation of complete history taking, clinical examination, laboratory and radiology examinations for clinicians working with limited hospital facilities and infrastructures.

Authors: Yanti Cici Apriza , Susanti Evi , Ediana Dina
Published: May 2023

BACKGROUND: Blood pressure may cause 7.5 million deaths and around 12.8% are deaths. The hypertension will continue and it is predicted in 2025, there are 29% of adults worldwide will be affected by hypertension. Based on data from Arosuka District Hospital in Solok, there were 133 (14.31%) patients with hypertension.
AIM: The purpose of this research was to determine factors influence hypertension.
METHODS: The type of this research was cross-sectional. The populations were all of hypertensive patients who visited the Arosuka District Hospital. They were 133 samples. They had been chosen using total sampling. Then, the data were analyzed by univariate and bivariate through Chi-square and multivariate tests with binary logistic regression.
RESULTS: The results showed that the variables related to hypertension were age (elderly = 66.2%, p = 0.0001, OR = 0.107), gender (female = 63.9%, p = 0.0001, OR = 3.917), index body mass (overweight = 69.2%, p = 0.0001, OR = 4.451), exercise (not exercising = 57.9%, p = 0.020, OR = 2.296), smoking (not smoking = 63.9%, p = 0.0001, OR = 0.255), and heart disease (undiagnosed = 87.2%, p = 0.005, OR = 7.000). In short, the variable related to hypertension were age (p = 0.0001, OR = 0.114), body mass index (p = 0.032, OR = 2.737), and heart disease (p = 0.002, OR = 12.231).
CONCLUSION: In conclusion, the most influential factor toward hypertension was heart disease. Prevention is done by having a heart-healthy diet, controlling blood pressure, maintaining a normal body weight, quitting smoking, and being diligent in doing physical activity.
Surgical management of tension pneumomediastinum in mechanically ventilated coronavirus disease 2019 patients
Authors: Ivanov Ivoslav A. , Mitev Dimo B. , Filipov Rumen A.
Published: May 2023

Introduction: Tension pneumomediastinum is an increasingly common condition since the COVID-19 pandemic’s onset. It is a life-threatening complication with severe hemodynamic instability that is refractory to catecholamines. Surgical decompression with drainage is the key point of treatment. Various surgical procedures are reported in the literature, but no cohesive approach has yet been developed.

Aim: The aim was to present the available options for surgical treatment of tension pneumomediastinum, as well as the post-interventional results.

Materials and methods: Nine cervical mediastinotomies were performed on intensive-care unit (ICU) patients who developed a tension pneumomediastinum during mechanical ventilation. The age and sex of patients, surgical complications, pre- and post-intervention basic hemodynamic parameters, as well as oxygen saturation levels, were recorded and analyzed.

Results: The mean age of patients was 62±16 years (6 males and 3 females). No postoperative surgical complications were recorded. The average preoperative systolic blood pressure was 91±12 mmHg, the heart rate was 104±8 bpm, and the oxygen saturation level was 89±6%, while the short-term postoperative values changed to 105±6 mmHg, 101±4 bpm, and 94±5%, respectively. There was no long-term survival benefit, with a mortality rate of 100%.

Conclusions: Cervical mediastinotomy is the operative method of choice in the presence of tension pneumomediastinum allowing an effective decompression of the mediastinal structures and improving the condition of the affected patients without improving the survival rate.

Published: May 2023

Introduction: Cigarette smoking is a preventable cause of cardiovascular morbidity and mortality. Despite the adverse effects of smoking, some studies have reported the term “smoker’s paradox’, meaning better outcomes in smokers following acute myocardial infarction.

Aim: The aim of the present study was to evaluate the relationship between smoking status and one-year mortality in patients with ST-segment elevation myocardial infarction (STEMI).

Materials and methods: This was a registry-based cohort study of STEMI patients from Imam-Ali hospital, Kermanshah, Iran. Consecutive STEMI patients (July 2016-October 2018) were stratified by smoking status and followed for one year. Cox proportional models were used to estimate crude, age-adjusted, and full-adjusted hazard ratios with 95% confidence intervals (HR, 95%CI).

Results: Of 1975 patients (mean age 60.1 years, 76.6% male) included in the study, 48.1% (n=951) were smokers (mean age 57.7 years, 94.7% male). Crude and age-adjusted HR (95% CI) for the associations of smoking and mortality were 0.67 (0.50-0.92) and 0.89 (0.65-1.22), respectively. After adjusting for age, sex, hypertension, diabetes, body-mass index, anterior wall myocardial infarction, creatine kinase-MB, glomerular filtration rate, left ventricular ejection fraction, low-density lipoprotein cholesterol, and hemoglobin, smoking was associated with increased risk of mortality: HR (95% CI: 1.56 (1.04-2.35).

Conclusions: In our study, smoking was associated with an increased risk of mortality. Although the smokers had a better outcome, this would be reversed after controlling for age and the other STEMI associated factors.
Adult morphology and redescription of Lestidiops indopacificus (Ege, 1953), with comments on the features of related species (Teleostei, Aulopiformes, Paralepididae)
Authors: Ho Hsuan-Ching , Lin Tzu-Yung
Published: May 2023

Two specimens representing the first known adults of Lestidiops indopacificus (Ege, 1953) are reported and described from Taiwan, and the validity and generic assignment of this species are confirmed. The origin of the pelvic fin directly below the dorsal-fin base shows that L. indopacificus belongs to the L. mirabilis species complex. It can be separated from its congeners by the position of the nostrils above the posterior end of the maxilla, the light body color with unevenly distributed melanophores in adults, and a distinct combination of meristic values and other morphological characteristics. New geographic records are reported for the two other current members of this species complex, L. mirabilis (Ege, 1933) and L. extremus (Ege, 1953). The diagnostic features that separate these three very similar species are discussed.

Le thanatopouvoir des passeurs djiboutiens
Authors: Lauret Alexandre
Published: May 2023

Cet article traite de la pratique de l’enterrement des migrants éthiopiens chez certains passeurs djiboutiens. Il s’appuie sur des données empiriques récoltées auprès de passeurs entre 2016 et 2021. La mort des migrants sur la route menant vers la péninsule Arabique devient un enjeu politique et sociétal pour la population locale et l’État. L’enterrement des corps est alors pris en charge par les passeurs, ce qui soulage les pouvoirs publics. Cette gestion permet par la suite une marge de manœuvre aux passeurs, devenus incontournables, pour négocier leur présence et faire pérenniser leur activité. Cette thanatopolitique a donc des conséquences sur le vivant : l’amenuisement entre les sphères licites et illicites, ainsi que l’évolution de l’éthique des passeurs autour du devoir funéraire.

Professional comportment is critical to the development of professional nurses. An essential component of professional identity, professional comportment should be integrated into lifelong learning. Defined as a nurse's professional behavior, it is “demonstrated through words, actions, and presence” (University of Kansas Medical Center). Students must learn professional comportment, and practicing nurses will need to become knowledgeable to meet the needs of the new generation of nurses.

On the fractional-order glucose-insulin interaction
Authors: Ahmed Ghada A.
Published: May 2023

We consider a fractional-order model of glucose and insulin interaction based on the intra-venous glucose tolerance test (IVGTT). We show the existence of the model's solution, uniqueness, non-negativity, and boundadness. In addition, for the proposed fractional-order model, we establish sufficient conditions for stability or instability. Some conditions for bifurcation in the proposed model are presented using bifurcation theory. Further, in the case of first order the model is discretized by applying the forward Euler scheme. We investigate how small the time step size must be chosen to guarantee that the steady state solution is an attractive fixed point of the discretized model. Numerical simulations that we provided support the analytical results.
$ k $NN local linear estimation of the conditional density and mode for functional spatial high dimensional data
Authors: Alshahrani Fatimah , Bouabsa Wahiba , Almanjahie Ibrahim M. , Attouch Mohammed Kadi
Published: May 2023

Traditionally, regression problems are examined using univariate characteristics, including the scale function, marginal density, regression error, and regression function. When the correlation between the response and the predictor is reasonably straightforward, these qualities are helpful and instructive. Given the predictor, the response's conditional density provides more specific information regarding the relationship. This study aims to examine a nonparametric estimator of a scalar response variable's function of a density and mode, given a functional variable when the data are spatially dependent. The estimator is then derived and established by combining the local linear and the $ k $ nearest neighbors methods. Next, the suggested estimator's uniform consistency in the number of neighbors (UNN) is proved. Finally, to demonstrate the efficacy and superiority of the acquired results, we applied our new estimator to simulated and real data and compared it to the existing competing estimator.
Accelerated American option pricing with deep neural networks
Authors: Anderson David , Ulrych Urban
Published: May 2023

Given the competitiveness of a market-making environment, the ability to speedily quote option prices consistent with an ever-changing market environment is essential. Thus, the smallest acceleration or improvement over traditional pricing methods is crucial to avoid arbitrage. We propose a method for accelerating the pricing of American options to near-instantaneous using a feed-forward neural network. This neural network is trained over the chosen (e.g., Heston) stochastic volatility specification. Such an approach facilitates parameter interpretability, as generally required by the regulators, and establishes our method in the area of eXplainable Artificial Intelligence (XAI) for finance. We show that the proposed deep explainable pricer induces a speed-accuracy trade-off compared to the typical Monte Carlo or Partial Differential Equation-based pricing methods. Moreover, the proposed approach allows for pricing derivatives with path-dependent and more complex payoffs and is, given the sufficient accuracy of computation and its tractable nature, applicable in a market-making environment.
L’Image au pied de la lettre. L’imagerie aménageuse au prisme de la (climate) fiction
Authors: Nivet Soline
Published: May 2023

Entre promesses commerciales et préfigurations optimistes des changements urbains à venir, les images produites par les aménageurs et les promoteurs immobiliers entretiennent a priori peu de relations avec d’autres discours, fictions ou imaginaires futuristes plus inquiets, notamment en termes de changement climatique. En empruntant à la théorie littéraire, et en particulier à celle qui étudie la Science-fiction et la Climate-Fiction, l’article propose d’autres modes de lecture de ces images, pour en révéler des aspects plus ambivalents.
Versailles et ses visiteurs étrangers, xviie-xixe siècle
Authors: Leroux Flavie
Published: May 2023

Cet article présente les premiers résultats issus de l’analyse du corpus documentaire rassemblé dans la base « Visiteurs de Versailles », publiée en 2019 par le Centre de recherche du château de Versailles. Les témoignages de voyageurs étrangers qui y sont recensés – plus de six cents auteurs – permettent de saisir les impressions laissées par Versailles à l’occasion de visites effectuées sur une période longue, allant du milieu du xviie siècle au début du xxe siècle. Au prisme d’une étude quantitative qui détermine qui vient, quand, d’où et pourquoi, peuvent d’abord être retracées la fréquentation du lieu et la typologie des visiteurs. Le but est ensuite de restituer les regards que ces derniers portent sur le domaine, son histoire, ses acteurs afin de reconstituer un certain imaginaire collectif de Versailles. Entre le réel et l’image construite et retranscrite dans les sources (récits de voyages, correspondances, journaux, mémoires), se dessinent ainsi les contours du mythe dans ses nuances, ses particularités, ses évolutions – qui pour beaucoup résonnent encore jusqu’à nos jours.
La fabrique dialectique du Songe de Versailles dans la littérature de voyage européenne du xviie siècle
Authors: Requemora Sylvie
Published: May 2023

La quasi-totalité des textes du xviie siècle compilés dans la base « Visiteurs de Versailles » du Centre de recherche du château de Versailles est dithyrambique. À de très rares exceptions, les récits de voyages à Versailles des visiteurs étrangers relèvent d’un genre viatique encomiastique convenu qu’il s’agit d’interroger, afin de comprendre comment se façonnent la mythographie et le « Songe de Versailles ». La « fabrique des fables » passe par des éloges viatiques paradoxaux et leur analyse littéraire aide à saisir le laboratoire scriptural de la fabula versaillaise. L’étude se déroule en trois points : d’abord la fabrique du Songe dithyrambique, puis l’envers du décor, Versailles comme singularité à blâmer, et enfin la fabula versaillaise, conçue comme une mythographie dialectique. La fabrique de la mythographie versaillaise entrelace les points de vue et les discours à la fois exotiques laudatifs et endotiques satiriques, mais aussi, vice versa, exotiques satiriques et endotiques émerveillés, ainsi que les discours encomiastiques, anti-encomiastiques et pseudo-encomiastiques ironiques. Le récit de voyage européen à Versailles est un genre viatique complexe : l’interroger génériquement permet d’affiner la fabrique d’une machine enchantée, l’étudier stylistiquement permet de découvrir un subtil système de duplicité ironique, chercher à le comprendre politiquement permet de débusquer un jeu diplomatique, entre flagorneries dithyrambiques, contemptions idéologiques et parallèles exotiques à effet de miroirs dissonants.

New generations of robots are designed to support humans with a variety of partially or fully automated

services. Such flexible and mobile service robots cooperate with humans or even act completely independent.

To achieve this, it is necessary to significantly improve their capabilities in terms of environment perception,

data processing and movement. At the same time, they must meet the highest standards of reliability and

safety. Innovative electronics enable the necessary improvements and thus appropriate robot behavior.

The aim of the Bionic RoboSkin project is to enhance the possibilities of a robot platform that is capable

of autonomously navigating its respective environment by means of a flexible bionic sensor skin. The sensor

platform is an autonomous underwater vehicle [AUV] that is based on the bionic principles of a Manta Ray

[1, 2, 3]. The newly developed sensor skin consists of a textile composite as a carrier for sensor elements and

provides moisture-resistant electrical connections for energy supply and communication. The integrated

sensor modules enable both the detection of touch and approach and the exploration of the environment. The

functionality of the sensor skin is targeting two service robotics applications: autonomous surveying of

underwater structures (e.g. inspection of pipelines) and semi-autonomous geo-exploration in difficult-to-access areas (e.g. monitoring in tunnel construction).

As a result, the paper presents the concept of a modular packaging platform for the use in a harsh marine

environment. The technologies used for the miniaturization of the sensor module by PCB embedding and for

outer housing development will be discussed in detail and a strong focus is put on packaging material

properties in sub-marine conditions.

Published: May 2023

Lead-frames have been widely used in the semiconductor package assembly field, and QFN (Quad flat no

leads) has the advantages of miniaturization and cost reduction of the semiconductor package. It has had

limited use in automotive or defense products because of its board-level reliability. Nevertheless, due to the

advantages of QFN packages, there is a trend toward using QFNs in automotive packaging. Automotive use

would also require a wettable flank design of the QFN leads and automated optical inspection (AOI) of

solder joints. New lead forming and surface finish technologies, including wettable flank design, are

expected to improve reliability and enable AOI inspection, but much research is needed.

This study investigated the board-level reliability of various QFN lead designs and surface finishes. All

lead frames with different structures and surface finish types were assembled under the same conditions

and then mounted on a daisy chain printed circuit board to evaluate board-level reliability. Accelerated

thermal cycling (TC) tests were performed per IPC-9701A rev 2/2006 over a temperature range of -40°C to

125°C and 6080cycles. Lastly, each package type tested was cross-sectioned, and failure analysis was

performed by observing the solder joint crack for all leg samples.

Published: May 2023

At IMAPS2021, we reported on 1-dimensional VCSEL arrays and the packaging technology developed for

these arrays, but this time we present the manufacturing workflow and look at the challenges presented by

the packaging of special long-wavelength 2-dimensional vertical-cavity surface-emitting laser (VCSEL)

arrays in various dimensions. We will show that available packaging technologies for epoxy application by

silk screening, die- and wire bonding can be adapted for the unique properties of the 2D VCSEL arrays,

delivering high accuracy for production with great overall yield. Proof of the excellent reliability and lifetime

will be given through mechanical and electro-optical testing results. The technologies developed for 2D laser

arrays will enable new devices for various new applications like high channel count interconnects for data

communication and high power VCSEL solutions for 3D sensing.

The perfected wire bonding process secured a homogeneous monometallic structure of the wire bonds, a

reduced, well defined bond loop height, with sufficient clearance of the bonding wire above the VCSEL

surface. Properly set-up manufacturing procedures for the packaging of the VCSEL arrays are necessary to

achieve high performance and reliability of the products presented. Processing of large 2D-VCSEL arrays

will be part of the paper.

2D arrays have enabled VCSEL technologies to address a wide range of new laser-based sensing applications.

VCSEL products vary from laser chips with only a few emitters for proximity sensors up to several thousands

of emitters for LiDAR systems. Applications include systems for the automotive, industrial, medical and

consumer markets. There is a strong and growing market opportunity for long wavelengths VCSELs, e.g.

based on InP material enabling single mode and multi-mode 2D-VCSEL arrays from 1.3 to beyond 2 µm.

For 3D sensing systems and free-space optical communication, long wavelength 2D-VCSEL arrays offer

improved eye safety and further benefits. The long wavelength VCSELs discussed in this paper can be

deployed in a wide range of sensing and optical communication applications.
Open-Cavity Plastic Packages: A Robust IC Packaging Solution for High-Reliability Applications
Authors: Sadri Sam , Tammen Tom
Published: May 2023

Fast-turn prototype package assembly is frequently employed for rapid IC design verification. Open-cavity

plastic packages (OCPP) are an attractive assembly option when commercial off-the-shelf (COTS) prototype

packages are not available. Any existing IC plastic packages, whether dummies, electrical test rejects or

excess inventory, can be quickly converted into robust open-cavity packages, ready to be assembled with

new die, creating new packages that will fit an established footprint. This allows them to be easily inserted

into test sockets and boards, so that no retooling or redesign is required.

OCPP is also a practical option for production when no onshore sources exist for a company’s required plastic

package assembly. This paper will delve into a case study example that details the process by which QP

Technologies’ OCPPs were selected and qualified for avionics ASIC provider DEI when its prior

package/assembly provider went out of business. The resulting packages passed MSL-3 solder stress

tests with results equivalent to factory-fresh parts.

Published: May 2023

The mobile device’s limited thermal budget hardly allows the use of a high-performance application (AP) at

its full speed. However, as artificial intelligence technologies has been rapidly applied for mobile devices,

the demand like high-speed and large-capacity signal processing is continuously increasing. Therefore,

controlling the heat generation of AP chip is becoming a key factor, and it is necessary to develop a Re-Distribution Layer (RDL) based Fan-Out Package (FOPKG) structure that does not increase the thickness of

the package while maximizing the die thickness for heat dissipation. The height of Cu post is getting higher

for the production of FOPKG that can apply thick die, and in this study, the world’s thickest photoresist

material (>350um thickness) was developed for the production of Cu post (>300um thickness). The effect of

light transmittance of the photoresist and the effect of solubility depending on the molecular structure of the

main polymer were studied for lithography process of thick photoresist. Based on the understanding of this

thick photoresist behavior, the optimal liquid type photoresist composition was developed. Through

lithography evaluation based on thick photoresist characteristics, deep-hole via implementation and Cu

electro-plating were performed to obtain a yield of Cpk 1.27 in the AP product design applied wafer.

Depending on this in-depth understanding and experimentation on thick photoresist, it is possible to build an

advanced research foundation of increasing the photoresist thickness and finer Cu post pitch to secure heat

dissipation characteristics and improve the degree of freedom of architecture.
Modeling the effect of hatched grounds on the radio-frequency performance of microstrip lines on flexible substrate

Published: May 2023

Cross-hatching of PCB grounds refers to a process in which certain ground planes appear as copper lattices;

regular openings are placed at regular intervals. Nowadays, the efficacy of ground hatching on rigid PCBs is

minimal. However, it is becoming essential for flexible hybrid electronics. Utilizing hatched grounds for

flexible applications could offer some benefits. Hatched grounds can perform dual roles, act as ground

surfaces, and offer structural support. Hatched grounds are more durable for bending and stretching

applications. Also, hatched grounds are desirable in terms of material conservation.

In this paper, we focus on studying how hatched grounds affect the RF performance of a straight microstrip

line. Simulations show that cross-hatched grounds with more than 50% filling produces good radio-frequency

performance. We will study the effect hatching pattern as well as the density of the hatching on the RF

performance of the microstrips. The theoretical modeling is considered in this work and fabricating aerosol

jet silver ink microstrip lines on PET substrates will be considered as an extension of this work.
