And another question: Say I want to watch, comment and share videos from #Peertube (and nothing else like microblogging). Where should I create an account, which platform/software has @… in mind? It's not Peertube itself, right? Because that's for publishing…

So here's a question: Is there an app for #Mastodon that plays videos from #Peertube directly in the timeline?
I'm on #android, but others would surely appreciate suggestions for

The bias of IID resampled backtests for rolling-window mean-variance portfolios
Backtests on historical data are the basis for practical evaluations of portfolio selection rules, but their reliability is often limited by reliance on a single sample path. This can lead to high estimation variance. Resampling techniques offer a potential solution by increasing the effective sample size, but can disrupt the temporal ordering inherent in financial data and introduce significant bias. This paper investigates the critical questions: First, How large is this bias for Sharpe Ratio…

Artist question: What’s the best media to set up an art portfolio for colleges?
#artist #question

#kde kmymoney also started to eat data. If Devs turn something from reliable and safe to unreliable and unsafe, the real question of liability comes into play. How can such a thing end in distribution?
Maybe we need to re-organize open source to have a reliable portfolio of applications, a kind of reliable #kde fr…

H3+ in irradiated protoplanetary disks: Linking far-ultraviolet radiation and hot water vapor
The likely JWST detection of vibrationally excited H3+ emission in the irradiated disk d203-506, reported by Schroetter et al., raises the question of whether cosmic-ray ionization is enhanced in disks within clustered star-forming regions, or if alternative mechanisms contribute to H3+ formation and excitation. We present a detailed model of the photodissociation region (PDR) component of a protoplanetary disk-comprising the outer disk surface and the photoevaporative wind-exposed to strong ex…

DeepRetro: Retrosynthetic Pathway Discovery using Iterative LLM Reasoning
Retrosynthesis, the identification of precursor molecules for a target compound, is pivotal for synthesizing complex molecules, but faces challenges in discovering novel pathways beyond predefined templates. Recent large language model (LLM) approaches to retrosynthesis have shown promise but effectively harnessing LLM reasoning capabilities for effective multi-step planning remains an open question. To address this challenge, we introduce DeepRetro, an open-source, iterative, hybrid LLM-based …

A Neuromorphic Electronic Nose Design
Rapid detection of gas concentration is important in different domains like gas leakage monitoring, pollution control, and so on, for the prevention of health hazards. Out of different types of gas sensors, Metal oxide (MOx) sensors are extensively used in such applications because of their portability, low cost, and high sensitivity for specific gases. However, how to effectively sample the MOx data for the real-time detection of gas and its concentration level remains an open question. Here, …

Dust-driven vortex cascades originating at water snow regions: A pathway to planetesimal formation
The origin of observed planetary systems, including our Solar System, as well as their diversity, is still an open question. Streaming instability (SI) is an important mechanism for the formation of gravitationally bound planetesimals, which can grow to form planetary embryos and eventually planets. Snow lines in a protoplanetary disk can assist this process, as they can form pressure maxima and promote both dust accumulation and growth. Since the sublimation of a volatile is gradual due to opa…
