BackgroundLearning from feedback – adapting behavior based on reinforcing and punishing outcomes – has been implicated in numerous psychiatric disorders, including substance misuse, post-traumatic stress disorder, and depression; an emerging literature suggests it may also play a role in suicidality. This study examined whether a feedback-based learning task with rewarding, punishing and ambiguous outcomes, followed by computational modeling, could improve near-term prospective prediction of suicide attempt in a high-risk sample.MethodVeterans (N=60) at high-risk for suicide were tested on a task of reward- and punishment-based learning, at multiple sessions across a one-year period. Each session was coded according to whether the participant had (1) an actual suicide attempt (ASA); (2) another suicide-related event (OtherSE) such as suicidal behavior or suicidal ideation-related hospital admission (but not an ASA); or (3) neither (noSE) in the next 90 days. Computational modeling was used to estimate latent cognitive variables including learning rates from positive and negative outcomes, and the subjective value of ambiguous feedback.ResultsOptimal responding on the reward-based trials was positively associated with upcoming ASA, and remained predictive even after controlling for other standard clinical variables such as current suicidal ideation severity and prior suicide attempts. Computational modeling revealed that patients with upcoming ASA tended to view ambiguous outcomes as similar to weak punishment, while OtherSE and noSE both tended to view the ambiguous outcome as similar to weak reward. Differences in the reinforcement value of the neutral outcome remained predictive for ASA even after controlling for current suicidal ideation and prior suicide attempts.ConclusionA reinforcement learning task with ambiguous neutral outcomes may provide a useful tool to help predict near-term risk of ASA in at-risk patients. While most individuals interpret ambiguous feedback as mildly reinforcing (a “glass half full” interpretation), those with upcoming ASA tend to view it as mildly punishing (a “glass half empty” interpretation). While the current results are based on a very small sample with relatively few ASA events, and require replication in a larger sample, they provide support for the role of negative biases in feedback-based learning in the cognitive profile of suicide risk.

A violência é um fenômeno social que persiste ao longo da história da humanidade e afeta o indivíduo e o coletivo. Considerando que a violência contra crianças representa uma seria violação dos direitos humanos. Seja física, sexual ou interpessoal, constitui uma preocupação central de saúde pública em nível global. Objetiva-se apontar a violência em crianças com relevância específica do estado de São Paulo e do período de tempo entre os anos de 2018 a 2022. Para tanto, procede-se à um estudo quantitativo e ecológico originado do Sistema de Informações de Agravos de Notificação (SINAM) – de Violência Doméstica, Sexual e/ou Outras Violências Interpessoais, disponíveis no Departamento de Informática do Sistema Único de Saúde (DATASUS). Desse modo, observa-se que as notificações de maus-tratos na infância, totalizaram 7.688 ocorrências entre os anos de 2018 a 2022. A negligência/abandono obteve o maior destaque, em seguida violência física, observou-se a mãe da vítima como principal agente agressor. O ano com maior número de casos o ano de 2022. Os lactentes de etnia branca foram os mais registrados no sistema, com 1325 relatos, o que permite concluir que os meninos são mais suscetíveis à negligencia e as meninas à violência física e sexual, sendo cinco vezes mais propensas a sofrer violência sexual que os meninos e as consequências de quaisquer que seja a violência pode gerar problemas eternos na vida dos lactentes.

Abstract
We show AlN/GaN HEMTs with in-situ SiN for passivation and regrown n+ GaN ohmic contacts using a selective etching process that is more suitable for device scaling. The regrown ohmic contacts have a clean and sharp edge definition with a contact resistance of 0.25 Ω·mm. The interfacial resistance between the regrown n+ GaN and the 2DEG at AlN/GaN interface is 0.058 Ω·mm, close to the theoretical quantum conductance limit. The fabricated devices with a gate length of 0.7 µm exhibit a maximum current density of 1.57 A/mm and on-resistance of 1.85 Ω·mm at a gate bias of 1 V.

Formacja intelektualno-duchowa jako punkt zwrotny w biografii moskiewskiego poety i teologa – Symeona Połockiego (1629–1680)
Authors: Mojżyn Norbert 
Published: January 2025

Osoba białoruskiego poety i teologa, Symeona Połockiego (Samuela Sitnianowicza-Piotrowskiego) stanowi kamień milowy w dziejach kultury rosyjskiej otwierającej się w 2 połowie XVII wieku na prądy artystyczne, filozoficzne i teologiczne płynące z Europy zachodniej. Punktem zwrotnym w życiu Połockiego, były studia w Akademii Wileńskiej, które przyczyniły się do sformowania się i krystalizacji dojrzałego światopoglądu społeczno-religijnego i wpłynęły na kształt jego pisarskiej twórczości w Moskwie. Dla wielu Białorusinów i Ukraińców w XVII wieku studia w Akademii były szansą wejścia do politycznej i duchownej elity Rzeczypospolitej, a nawet dalej, w Państwie Moskiewskim. Spośród studentów białoruskich i ukraińskich w Wilnie rekrutowało się wielu członków, w tym duchownych, Kościoła unickiego (Unia brzeska 1596). W tym celu w 1617 roku przy klasztorze św. Trójcy erygowano konwikt dla studentów zakonu bazylianów.
Własnoręczne notatki Samuela Sitnianowicza-Piotrowskiego wskazują, że był on studentem Akademii Wileńskiej oraz pozwalają przypuszczać, że w tym mieście i w tym czasie (1650-1654) wstąpił do zakonu bazylianów. W niniejszym artykule przedstawiono argumenty świadczące zarówno o studiach w Wilnie, jak i przynależności Połockiego do zakonu bazylianów, które stały się punktem zwrotnym w jego dalszej karierze artystycznej i teologicznej.

Abstract
We present new observations of the cosmic ultraviolet background (CUVB) at high Galactic latitudes (∣b∣ > 40∘), made using the Alice UV spectrograph on board the New Horizons spacecraft. These observations were taken at about 57 au from the Sun, outside much of the foreground emission affecting previous missions, and allowed a new determination of the spectrum of the CUVB between 912–1100 Å and 1400–1800 Å. We found a linear correlation between the CUVB and the Planck E(B − V) with offsets at zero-reddening of 221 ± 11 photon units at 1000 Å and 264 ± 24 photon units at 1500 Å (4.4 ± 0.2 nW m−2 sr−1 at 1000 Å and 5.3 ± 0.5 nW m−2 sr−1 at 1500 Å). The former is the first firm detection of the offset in the range 912–1100 Å while the latter result confirms previous results from the Galaxy Evolution Explorer, showing that there is little emission from the solar system from 1400 to 1800 Å. About half of the offset may be explained by known sources (the integrated light of unresolved galaxies, unresolved stars, emission from ionized gas, and two-photon emission from warm hydrogen in the halo) with the source of the remaining emission as yet unidentified. There is no detectable emission below the Lyman limit with an upper limit of 3.2 ± 3.0 photon units.
The Influence of General Relativity on the Spins of Celestial Bodies in Inclined Orbits

Abstract
Through the Rossiter–McLaughlin effect, several hot Jupiters have been found to exhibit spin–orbit misalignment and even retrograde orbits. The high obliquity observed in these planets can be attributed to two primary formation mechanisms, as summarized in the existing literature. First, the host star's spin becomes misaligned with the planetary disk during the late stages of star formation, primarily due to chaotic accretion and magnetic interactions between the star and the planetary disk. Second, the orbital inclination of an individual planet can be excited by dynamical processes such as planet–planet scattering, the Lidov–Kozai cycle, and secular chaos within the framework of Newtonian mechanics. This study introduces a third mechanism, where, within the framework of general relativity, the post-Newtonian spin–orbit coupling term induces precession of the host star's spin around the orbital angular momentum. The orbital inclination, relative to a reference plane, can expand the range of deviation in the spatial orientation of the bodies’ spins from the plane's normal. The varying amplitude and period of spin precession for both the star and the planet are derived theoretically, and the results, which can be applied without restriction, agree well with numerical simulations.
Rotating Neutron Stars with Relativistic Ab Initio Calculations

Published: January 2025

Abstract
The equation of state (EOS) of extremely dense matter is crucial for understanding the properties of rotating neutron stars. Starting from the widely used realistic Bonn potentials rooted in a relativistic framework, we derive EOSs by performing state-of-the-art relativistic Brueckner–Hartree–Fock calculations in the full Dirac space. The self-consistent and simultaneous consideration of both positive- and negative-energy states (NESs) of the Dirac equation allows us to avoid the uncertainties present in calculations where NESs are treated using approximations. To manifest the impact of rotational dynamics, several structural properties of neutron stars across a wide range of rotation frequencies and up to the Keplerian limit are obtained, including the gravitational and baryonic masses, the polar and equatorial radii, and the moments of inertia. Our theoretical predictions align well with the latest astrophysical constraints from observations of massive neutron stars and joint mass–radius measurements. The maximum mass for rotating configurations can reach up to 2.93 M
⊙ for Bonn A potential, while the radius of a 1.4 M
⊙ neutron star in the nonrotating case can be extended to around 17 km through constant baryonic mass sequences. Relations with good universalities between the Keplerian frequency and static mass as well as radius are obtained, from which the radius of the black widow PSR J0952-0607 is predicted to be less than 19.58 km. Furthermore, to understand how rotation deforms the equilibrium shape of a neutron star, the eccentricity is also calculated. The approximate universality between the eccentricity at the Keplerian frequency and the gravitational mass is found.

Les bases de données événementielles sont importantes pour la compréhension des risques d’origine naturelle et la limitation des dommages associés. En France, en zones de montagne, les phénomènes naturels potentiellement dommageables et les enjeux sont nombreux et diversifiés, mais les bases de données recensant les informations liées aux événements du passé sont peu nombreuses. La base de données du service de Restauration des terrains de montagne de l’Office national des forêts (BD-RTM) capitalise l’information selon une approche multi-phénomènes et sur une longue période temporelle en associant une alimentation régulière par des observations directes et une compilation historique a posteriori. Cet article présente les caractéristiques principales de cette source d’information originale. À partir de l’exemple du département de l’Isère (38), celui recensant le plus d’événements sur les 12 couverts par la BD-RTM, (1) l’historique et la structure de cette base de données, notamment l’origine des données, sont présentés et (2) la richesse et la diversité des informations consignées sont illustrées. Dans la BD-RTM, 5888 événements sont recensés en Isère au 31/12/2023, dont près de 70 % sont des crues torrentielles et des glissements de terrain. Également, 85 % des événements enregistrés ont causé des dommages. Une nette augmentation dans la chronologie des événements est visible à partir des années 2000, en moyenne 85 événements sont répertoriés chaque année. Ces informations sont disponibles pour des analyses spatiales et temporelles plus approfondies : statistiques, historiques, couplages avec d’autres données, etc.
Achieving Large-Scale HBM Integration with Adaptive Pad Stacks on Molded Embedded Bridge Die Interposers
Authors: San Jose Benedict , Sandstrom Cliff , Bishop Craig , Olson Tim 
Published: January 2025

Chiplets and heterogeneous integration are now common vernacular in the semiconductor industry. One of the more pressing issues facing device designers and system architects in this new reality is the insatiable appetite for high-bandwidth memory tightly integrated with GPU, CPU and other chiplet processing devices. This ever-increasing drive for higher levels of integration is resulting in module sizes that now exceed the bounds of the industry’s current de-facto standard silicon interposer solutions. With module dimensions exceeding 50 mm on a side, the industry is transitioning to organic substrates or molded fan-out interposers with embedded bridge die. These embedded bridge technologies provide a practical roadmap for significant module size growth to 100mm per side and beyond. As module sizes continue to grow, the number of embedded bridge die similarly increase. An emerging device currently in design now exceeds 20 bridge die. During assembly of the molded interposer, manufacturing tolerances to achieve the true positions required for all the bridge die become incredibly challenging to achieve in a cost-effective high-volume process. Within this paper, an innovative solution, Adaptive Pad Stacks, will be presented which increases process tolerances by up to 10X versus the conventional approach. For example, the ± 1.5 µm true position required for 35 µm pitch bridge die interfaces can be achieved with a die attach specification allowing up to ± 25 µm. Adaptive Pad Stacks utilize Adaptive Patterning® and mask-less laser direct imaging photolithography to not only deliver high yield on large scale interposers, but also remove the historical challenge with reticle stitching.

Published: January 2025

Copper bonding (direct and hybrid) in interconnection – one of these concepts, will benefit from an electroplated nanograined copper. The copper grain size for this purpose should not change for up to 1 month at RT, but increases up to 10 times under bonding conditions. It is desirable that the electroplated copper has low impurities and achieves strong Cu2Cu bonds at low temperatures without voids. The electrodeposition of nanograined copper with IntraCu® SC-4 electrolyte was investigated with voltammetry, SEM, EBSD, GDEOS and SIMS methods. The effect of current density, grain size of seed layer and geometry of vias on the structure of nanograined copper was established. The resulting coatings were characterized for: • Grain size (less than 150nm) stability at room temperature storage - unchangeable more than 3 weeks (almost suppressed self-annealing behavior); • Increasing of the size of copper grains after different annealing temperature and duration – from 120⁰ to the 260⁰ C, from 1 to 10 hours, also with different annealing profile. Size of grains is shown to increase more than 7 times-10, even at lower than 200⁰ C temperature A linear relationship between the impurities, voids in the layer and the concentration of additives (as well current density) was found. According to this relation, the size, stability in time, impurities and annealing behavior of the nanocrystals could be predicted and controlled.
Novel Pressure-less Adhesive Dispensing Strategy for Thin Die Applications
Authors: Quattrocchio Matteo Luca 
Published: January 2025

The automotive electronics market is facing increasingly demanding reliability requirements, along with restrictive European and international environmental legislations targeting the elimination of lead-based materials in electronics packages. As a result, pressure-less Ag-sinter adhesives have been identified as one of the most mature lead-free bonding materials, with thermal and electrical performances comparable or superior to lead-tin alloys, as well as reliability performances compliant with automotive mission profiles. Simultaneously, there is a clear trend towards using thinner dice (<200 µm) in the semiconductor packaging industry for automotive applications, driven primarily by the demand for devices with higher electrical performance. This poses a challenge for the use of pressure-less adhesives, as they have a natural tendency to climb up the vertical sides of the die, potentially causing adhesive to flow over the die surface and resulting in short circuits or yield loss during subsequent IC assembly process steps. Currently, one of the most established processes for controlling the rise of adhesive on the vertical sides of thin dice is 2D screen printing (also known as stencil printing). This process involves selectively printing a complete pattern of adhesive material onto a substrate, onto which the die can then be placed without the need to forcibly spread the pressure-less adhesive to achieve full die backside coverage. However, this process is associated with significant material wastage and is only applicable to flat substrates. The aim of this paper is to introduce an innovative dispensing strategy for thin dice, which dispenses the adhesive in a spiral pattern shape. This technique can be applied to both flat (2D) and non-flat (3D or downset) substrates and minimizes material waste by utilizing a standard time-pressure dispensing system. The paper provides an overview of the concept and the underlying dispensing strategy developed by Besi, as well as an example of its application for die thicknesses down to 110um and 3D substrates in some power packages manufactured by STMicroelectronics. Process capability is validated, and package reliability is demonstrated up to MSL3 + 1000 thermal cycles through scanning acoustic microscopy.
Chiplets and Heterogeneous IC Packaging: Building Blocks and Tradeoffs
Authors: Kelly Mike , Hiner Dave , Jayaraman Suresh 
Published: January 2025

Chiplets-based IC packages have arrived. This year, many more customers are developing and qualifying their products at Amkor and in the outsourced semiconductor assembly and test (OSAT) and foundry space at large. The rationale for this surge into new multi-die embodiments has been well documented and discussed. In the final analysis, the chiplets approach has become the preferred alternative to large system on chip (SoC) designs. The chiplets approach often permits a better product performance, while lowering total silicon costs. This also enables more transistors in the package than an equivalent SoC, and most importantly, reuse flexibility that reduces time-to-market (TTM) for follow-on products. Heterogeneous IC packages are more expensive than traditional alternatives, for example a single-die Flip Chip ball grid array (FCBGA), but this increase is often offset by lower total silicon cost and the positive time-to-market benefits. However, moving to a heterogeneous approach requires a strong infrastructure to be established for: 1) design, 2) new IC and package structure development and fabrication techniques, and 3) electrical test. IC packaging options to support chiplets have now consolidated into just a few primary constructions that are being developed in the industry and entering early production. These package configurations are much simpler than the now-confusing terminology currently present in the industry. This presentation will review these constructions, simplify their attributes and provide some groundwork for doing the tradeoff analyses during the package construction evaluation and down-selection phase of a project. These higher density integration approaches create modules which integrate the die or chiplets that need ultra fine-line routing for die-die interfaces. Today, these are: (a) modules based on silicon interposers – 2.5D Through Silicon Via (TSV), (b) modules based on High-Density Fan-Out (HDFO) multi-layer redistribution layer (RDL) approaches or (c) modules with bridges. Silicon die can be singular planar devices or combinations using 3D die integration achieved with copper (Cu)-hybrid construction. 1. (c) Bridges (S-Connect) (RDL + Bridge(s)) In Amkor, 2.5D TSV with silicon interposers technology has been in high volume manufacturing (HVM) since 2017. HDFO packaging is internally qualified and currently being qualified for multiple customer products.
