Perturbed Public Voices (P$^{2}$V): A Dataset for Robust Audio Deepfake Detection
Current audio deepfake detectors cannot be trusted. While they excel on controlled benchmarks, they fail when tested in the real world. We introduce Perturbed Public Voices (P$^{2}$V), an IRB-approved dataset capturing three critical aspects of malicious deepfakes: (1) identity-consistent transcripts via LLMs, (2) environmental and adversarial noise, and (3) state-of-the-art voice cloning (2020-2025). Experiments reveal alarming vulnerabilities of 22 recent audio deepfake detectors: models trai…

I’m so proud of my little brother.
I just spoke to him in his dorm room at a top 30 college here in the US, he just arrived for freshman orientation.
He got in on a full ride - tuition, housing, food, books, travel, stipend for daily expenses. Won a competitive scholarship to do so.
More than that, he’s had a tougher road than most to get there:
- he had to suddenly move away from Manila, Philippines (where he grew up) in middle school because of COVID restrictions that didn’t let kids go outside (2020)
- then, just as he adjusted to school and a different language in our home country, Ukraine, Russia invaded (2022)
- he stayed in Greece for a month while I was calling our congressional representative here in NY and negotiating with the US embassy to get them a visa ASAP to enter the US and be with me and my husband. There were no paths for Ukrainian refugees yet, we just wanted them with us temporarily for a few months to figure out what options they even had next.
- he had to wait, not going to school, with no clue where they’d move next, until TPS became available to Ukrainians and they got to stay here in the US
- then he had to continue high school in yet another system, yet another country, amidst news of bombings and destruction back home
- my mother wasn’t allowed to work for months while their documents were pending, so we had to raise money with a public GoFundMe campaign and my husband and I maxed out our credit cards to help them get by
- they shared a one-room cottage for the first year, graciously hosted for free by an elderly local couple
- he saw a therapist who also graciously took him in for free while they didn’t have insurance
- he had to graduate high school amidst news of other immigrant students getting arrested, detained, and deported at their own graduations around the country
- he wasn’t sure if he would even make it to college as this administration publicly considered canceling TPS for Ukrainians and cutting off their pathway to maintaining legal status.
We don’t know what tomorrow holds. But he’s there. He’s on campus. He got to go to college.
I love him so much.

(2020) Economic growth is incompatible with biodiversity conservation #environment

Economic growth is incompatible with biodiversity conservation
The increase in resource consumption and polluting emissions as a result of economic growth is not compatible with biodiversity conservation. However, most international policies on biodiversity and sustainability advocate economic growth. These are the main conclusions of the study "Biodiversity policy beyond economic growth," published this week in the scientific journal Conservation Letters. This contradiction became clear after a review of international scientific and policy work on the sub…

Analysis and Constructive Criticism of the Official Data Protection Impact Assessment of the German Corona-Warn-App
On June 15, 2020, the official data protection impact assessment (DPIA) for the German Corona-Warn-App (CWA) was made publicly available. Shortly thereafter, the app was made available for download in the app stores. However, the first version of the DPIA had significant weaknesses, as this paper argues. However since then, the quality of the official DPIA increased immensely due to interventions and interactions such as an alternative DPIA produced by external experts and extensive public disc…

Expressive Power of Graph Transformers via Logic
Transformers are the basis of modern large language models, but relatively little is known about their precise expressive power on graphs. We study the expressive power of graph transformers (GTs) by Dwivedi and Bresson (2020) and GPS-networks by Rampásek et al. (2022), both under soft-attention and average hard-attention. Our study covers two scenarios: the theoretical setting with real numbers and the more practical case with floats. With reals, we show that in restriction to vertex properti…

Superpolynomial convergence in the Riemann Rearrangement Theorem

https://arxiv.org/abs/2508.02489 https://arxiv.org/pdf/2508.02489

Superpolynomial convergence in the Riemann Rearrangement Theorem
Let $x \in \mathbb{R}$ be arbitrary and consider the `greedy' approximation of $x$ by signed harmonic sums: given $a_n = \sum_{k \leq n} \varepsilon_k/k$ with $\varepsilon_k \in \left\{-1,1\right\}$, we set $\varepsilon_{n+1} = 1$ if $a_n \leq x$ and $\varepsilon_{n+1} = -1$ otherwise. Bettin-Molteni-Sanna showed (Adv. Math. 2020) that this procedure has remarkable approximation properties: for almost all $x \in \mathbb{R}$ one has superpolynomial convergence in the sense that for every $k \in …

Extended c-differential distinguishers of full 9 and reduced-round Kuznyechik cipher
This paper introduces {\em truncated inner $c$-differential cryptanalysis}, a novel technique that for the first time enables the practical application of $c$-differential uniformity to block ciphers. While Ellingsen et al. (IEEE Trans. Inf.

Nonlinear-linear duality for multipath quantum interference
In quantum optics, the postselection amplitude of a nondegenerate parametric down-conversion (PDC) process is linked to a beamsplitter (BS) via partial time reversal, up to a normalization coefficient which is related to the parametric gain [Proc. Natl. Acad. Sci. USA 117, 33107 (2020)]. A special example where the gain is low is reminiscent of Klyshko's advanced-wave picture in quantum imaging. Here, we propose and prove a generalized duality for multiple spatial paths connecting a quantum non…

In order to understand solar atmospheric heating it is important to test heating models against spatially resolved data from solar active regions. Here we model a small active region, AR~12760 observed on 2020 April 28, with the GX Simulator package by fitting the EUV intensities in wavebands observed by Solar Dynamics Observatory's Atmospheric Imaging Assembly. We assume the temporally and spatially averaged heating rate along a loop has a power-law dependence on loop length, $L$ and average m…

Good Morning #Canada
#HappyBirthday to me. It's my 69th, and mentally, I feel young, but parts of my body have exceeded the "best before date." According to bornglorious .com there are 137 "famous" Canadians born on August 24th. Most are nobodies like me - politicians, actors, or NHL players you've never heard of. But there are a few notables. Like Alex Colville (1920-2013), a favourite Canadian conceptual painter. Or chain-smoker René Lévesque (1922-1987), who tried to tear Canada apart. But perhaps the Canadian born on this day with the most impact is Rocky Johnson (1944-2020). Born in Amherst, Nova Scotia, Johnson was a Canadian pro wrestler and the first black champion in WWE history. Oh yeah.... he was also the father of Dwayne "The Rock" Johnson.
