Integrative, Scalable Modeling of Hydrological Systems with MBSE and HFGT
Worsening global challenges in the Anthropocene demand complex, adaptive solutions grounded in a systems-level understanding of coupled social and environmental dynamics. However, existing modeling approaches often fall short due to disciplinary silos, limited scalability, and the absence of shared ontological frameworks. Model-Based Systems Engineering (MBSE), when integrated with Hetero-functional Graph Theory (HFGT), offers a powerful methodology for modeling systems of systems while preserv…

Social Learning with Limited Attention: Negative Reviews Persist under Newest First
We study a model of social learning from reviews where customers are computationally limited and make purchases based on reading only the first few reviews displayed by the platform. Under this limited attention, we establish that the review ordering policy can have a significant impact. In particular, the popular Newest First ordering induces a negative review to persist as the most recent review longer than a positive review. This phenomenon, which we term the Cost of Newest First, can make t…

Well, fuck. Silver had a manic minute and knocked my laptop out of my hand and then stood on its open screen, breaking it!
Most expensive dog sitting I've ever done.
Struggling along with the external 1080p display I brought with me.
Ah well, in theory an easy fix since this ia a Framework 13, and also gives me the excuse I needed to go up to the 2.8k model.

Save me your fake nostalgia, people. There is only one true #BSOD, and it never was blue. 💣

Closely-cropped screenshot of a modal dialog box from the classic #Macintosh operating system. It is a sparse, black-and-white window displaying a cartoon-like, cannonball bomb icon, the words “Sorry, a system error occurred,” and a simple button labeled “Restart.”

If my bio didn’t make it obvious, I’m an anarcho-syndicalist who’s bisexual, gender-fluid, and autistic!

The image features a flag divided diagonally into two equal parts, with the top half in red and the bottom half in black. In the center of the flag, there is a white infinity symbol, which is a continuous loop resembling the number 8 on its side. The infinity symbol is bold and stands out against the contrasting background colors. The red and black sections of the flag are evenly split, creating a striking visual effect. The overall design is simple yet powerful, with the infinity symbol servin…
The image shows two flags displayed on a windowsill. On the left is a flag with horizontal stripes in the colors pink, red, white, purple, black, and blue, representing the transgender pride flag. On the right is a smaller flag with the traditional rainbow colors, symbolizing LGBTQ+ pride. Both flags are mounted on wooden poles. In the background, there is a view of a residential area with houses and a cityscape in the distance. A potted plant is visible on the windowsill, adding a touch of gre…
The image is an infographic titled "What's in a Flag? Bisexual Flag" for Pride Month. It features the bisexual flag, which consists of three horizontal stripes: pink at the top, purple in the middle, and blue at the bottom. The flag is designed by Michael Page and was unveiled in December 1998. The infographic explains that the flag was created to represent and increase visibility of bisexuals in the LGBT community and society as a whole. The infographic includes a section titled "The Invisibl…

Assisted Fibre Inflation in Perturbative LVS
We propose a multi-field fiber inflation scenario in type IIB perturbative large volume compactifications, showing that the multi-field dynamics suppresses trans-Planckian displacements of the canonical inflaton. Considering a concrete K3-fibred Calabi-Yau (CY) threefold with $h^{1,1}({\rm CY})=3$ and having certain underlying symmetries, we show that the presence of multi-fibre moduli creates an assisted inflation scenario where multiple moduli collectively help in producing the cosmological o…

**English:** This black-and-white photograph depicts a small outdoor kiosk or stall. The kiosk is adorned with various plush toys, prominently featuring several Mickey Mouse dolls hanging at the top. Below the toys, there are shelves stocked with small items, possibly keychains or small trinkets. The front of the kiosk displays images of ice cream cones and bottles of beverages, suggesting that it might also sell refreshments. The setting appears to be a park or a fair, with trees and a fence v…
English alt text: A black and white photo of a park path flanked by evenly spaced trees with their trunks painted white at the base. A few people walk quietly along the paved walkway, framed by natural foliage. Trash bins are visible in the background, contributing to the everyday tranquility of the scene. 中文替代文本（Chinese alt text）：一张黑白照片展示了一条公园小路，路两旁是整齐排列的树木，树干下部涂有白漆。几位行人安静地走在铺设的步道上，周围环绕着自然景色。背景中可见垃圾桶，为这幅日常宁静的画面增添了现实感。
English alt text: Two large ducks shaped object float in a narrow water channel. One duck is in the foreground, reflected in the water, while the other is partially hidden behind a metal grid structure. The scene features an interesting contrast between the playful shapes of the ducks and the rigid geometry of the metal structure. Trees and a building with windows are visible in the background. 中文替代文本（Chinese alt text）：两只大型鸭型物漂浮在一条狭窄的水渠中。一只靠近前方，在水中有清晰倒影；另一只则部分被左侧的金属网格结构遮挡。画面中趣味盎然的鸭子与硬朗的金属框架形成鲜…
English alt text: A wooden platform nestled among tall trees, covered by a striped canopy. A person stands on the platform, which is accessed by a stairway. Beneath the structure is a bilingual sign, possibly in Chinese, and fencing and foliage frame the background, suggesting a serene park or nature retreat. 中文替代文本（Chinese alt text）：一座建在高大树木之间的木质平台，上方覆盖着条纹遮阳篷。一人站在平台上，通往平台的楼梯清晰可见。平台下方有一块双语标牌（可能含有中文），背景中的树木和围栏营造出宁静的自然氛围。

Sociophysics models inspired by the Ising model
The Ising model, originally developed for understanding magnetic phase transitions, has become a cornerstone in the study of collective phenomena across diverse disciplines. In this review, we explore how Ising and Ising-like models have been successfully adapted to sociophysical systems, where binary-state agents mimic human decisions or opinions. By focusing on key areas such as opinion dynamics, financial markets, social segregation, game theory, language evolution, and epidemic spreading, w…

Next stop in our NLP timeline is 2013, the introduction of low dimensional dense word vectors - so-called "word embeddings" - based on distributed semantics, as e.g. word2vec by Mikolov et al. from Google, which enabled representation learning on text.
T. Mikolov et al. (2013). Efficient Estimation of Word Representations in Vector Space.

Slide from the Information Service Engineering 2025 lecture, lecture 02, Natural Language Processing 01, NLP Timeline. The timeline is in the middle of the slide from top to bottom, indicating a marker at 2013. On the left, a diagram is shown, displaying vectors for "man" and "woman" in a 2D diagram. An arrow leades from the point of "man" to the point of "woman". Above it, there is also the point marked for "king" and the same difference vector is transferred from "man - > woman" to "king - ?…

Efficient Estimation of Word Representations in Vector Space
We propose two novel model architectures for computing continuous vector representations of words from very large data sets. The quality of these representations is measured in a word similarity task, and the results are compared to the previously best performing techniques based on different types of neural networks. We observe large improvements in accuracy at much lower computational cost, i.e. it takes less than a day to learn high quality word vectors from a 1.6 billion words data set. Fur…
