ImpReSS: Implicit Recommender System for Support Conversations
Following recent advancements in large language models (LLMs), LLM-based chatbots have transformed customer support by automating interactions and providing consistent, scalable service. While LLM-based conversational recommender systems (CRSs) have attracted attention for their ability to enhance the quality of recommendations, limited research has addressed the implicit integration of recommendations within customer support interactions. In this work, we introduce ImpReSS, an implicit recomme…

War is an unconscionable horror. The illusions of "international law" and "rules of war" have lead us to believe that war can be clean, managed, and "civilized."
But wars are fought by humans and humans are messy. Humans are not well suited to following orderly rules. Humans respond to their environment. Humans in extraordinary situations can be extraordinarily vindictive and brutal. Sufficiently traumatized humans can act without a conscience, spreading trauma like an infection. If humans respond to their situation, then there can be no "civilized" war because war is itself an situation outside of the society. It is a place that promotes antisocial behavior and punishes pro-social behavior. War cannot be expected to follow "international law" because it is what fills the void created by the failure of "international law" (so long as we rely on nations).
To call for war is to inflict atrocities on civilians. It is to kill the parents and children who serve, and to destroy the combatants who survive. It is to infect both sides with a trauma that will spread if untreated, when soldiers come home or when they become mercenaries in other wars.
And yet... there are times when the brutality, the incompetence, the evil becomes so unbearable that no other option exists, when taking up arms is simply bringing symmetry to an existing asymmetric conflict. There are times when the worst possible thing is inescapable, though it can never be justified.
In this new era of war, in the scramble of conflict under the collapsing of the (poorly named) "Pax Americana," I hope that we, the people, can understand that war is not a tool to fulfill an objective. It is not part of a larger strategy. It is not an extension of deplomacy.
War is a failure.
While it may be the only way to deal with the irrational - the genocidal, the slaver, the dictator - it is still a failure. It is a failure to build a world in which these people can't control armies and economies, can't turn populations in to cults and bend nations to their will.
And we will continue to have such wars until we unite against those who would use as as pawns, who would control our lives and lead us to our deaths. We will have these wars until we unite, as one world, against those rulers. This is what I mean, and what a lot of other people mean, when we say, "No War, but Class War."

High-gain model-following control for trajectory tracking
We consider trajectory tracking for minimum-phase nonlinear systems in Byrnes-Isidori form using the model-following control (MFC) architecture. The tracking problem is motivated by a hierarchical control concept where a higher-level instance provides the reference trajectory at run-time. We present a computational efficient implementation of the feedback linearisation MFC design, and apply high-gain feedback in the process control loop (PCL) to achieve practical tracking in presence of Lipschi…

Feeling Machines: Ethics, Culture, and the Rise of Emotional AI
This paper explores the growing presence of emotionally responsive artificial intelligence through a critical and interdisciplinary lens. Bringing together the voices of early-career researchers from multiple fields, it explores how AI systems that simulate or interpret human emotions are reshaping our interactions in areas such as education, healthcare, mental health, caregiving, and digital life. The analysis is structured around four central themes: the ethical implications of emotional AI, …

Nice!
One of the better #litrpg webnovels I've read, Worth the Candle by Alexander Wales, is being made into a #manhwa / #manga!
Already enjoying the story! 😄

Worth the Candle
Juniper was always the Dungeon Master, never the player. He was always a creator of worlds rather than the one who walked within them…until now. Somehow, the tables have turned in the most dramatic way possible. Juniper finds himself in a world filled with the wildest fantasies a mind could come up with, and his fingerprints are all over it. Throughout this world, echoes of his own ideas and plots leave him feeling like he’s always one step behind. He finds bits and pieces of ancient infl…

3 out of 7 recommended news stories are about Trump failing.
I would be happier about it if it did not imply Putin was winning. This is bad for everyone, but especially Ukraine.
Trump’s ego, fealty, and idiocy is going to destroy the world if Europe, the Global South, and other democratic nations don’t take the reins from the USA.

glass: ordered set data structure for client-side order books
The "ordered set" abstract data type with operations "insert", "erase", "find", "min", "max", "next" and "prev" is ubiquitous in computer science. It is usually implemented with red-black trees, $B$-trees, or $B^+$-trees. We present our implementation of ordered set based on a trie. It only supports integer keys (as opposed to keys of any strict weakly ordered type) and is optimized for market data, namely for what we call sequential locality. The following is the list of what we believe to be …

Implied Probabilities and Volatility in Credit Risk: A Merton-Based Approach with Binomial Trees
We explore credit risk pricing by modeling equity as a call option and debt as the difference between the firm's asset value and a put option, following the structural framework of the Merton model. Our approach proceeds in two stages: first, we calibrate the asset volatility using the Black-Scholes-Merton (BSM) formula; second, we recover implied mean return and probability surfaces under the physical measure. To achieve this, we construct a recombining binomial tree under the real-world (natu…

Fine-structure Line Atlas for Multi-wavelength Extragalactic Study (FLAMES) III: [C II] as Tracer, Crisis of SFR, [O III]/[C II] at High-z, New Answers and New Questions
In the final paper of this series, we discuss new perspectives and challenges in the study of interstellar medium (ISM), leveraging comprehensive catalogs and physical insights presented in our previous papers. We focus on key questions of far-infrared (FIR) fine-structure lines (FSLs): their origins, diagnostic value, and implications of correlations. Our analysis reveals a strong dependence on elemental abundance, so that FSL/H$α$ traces metallicity, [N II]/[C II] traces N/O, and $\sim$80% o…

From Flat to Feeling: A Feasibility and Impact Study on Dynamic Facial Emotions in AI-Generated Avatars
Dynamic facial emotion is essential for believable AI-generated avatars; however, most systems remain visually inert, limiting their utility in high-stakes simulations such as virtual training for investigative interviews with abused children. We introduce and evaluate a real-time architecture fusing Unreal Engine 5 MetaHuman rendering with NVIDIA Omniverse Audio2Face to translate vocal prosody into high-fidelity facial expressions on photorealistic child avatars. We implemented a distributed t…
