Transfer learning (TL) has emerged as a powerful tool for improving estimation and prediction performance by leveraging information from related datasets. In this paper, we repurpose the control-variates (CVS) method for TL in the context of scalar-on-function regression. Our proposed framework relies exclusively on dataset-specific summary statistics, avoiding the need to pool subject-level data and thus remaining applicable in privacy-restricted or decentralized settings. We establish theoretical connections among several existing TL strategies and derive convergence rates for our CVS-based proposals. These rates explicitly account for the typically overlooked smoothing error and reveal how the similarity among covariance functions across datasets influences convergence behavior. Numerical studies support the theoretical findings and demonstrate that the proposed methods achieve competitive estimation and prediction performance compared with existing alternatives.

ARXIV PREPRINT 1 Attention-Based V ariational Framework for Joint and Individual Components Learning with Applications in Brain Network Analysis Yifei Zhang, Meimei Liu, and Zhengwu Zhang Abstract Brain organization is increasingly characterized through multiple imaging modalities, most notably structural connectivity (SC) and functional connectivity (FC). Integrating these inherently distinct yet complementary data sources is essential for uncovering the cross-modal patterns that drive behavioral phenotypes. However, effective integration is hindered by the high dimensionality and non-linearity of connectome data, complex non-linear SC-FC coupling, and the challenge of disentangling shared information from modality-specific variations. To address these issues, we propose the Cross-Modal Joint-Individual Variational Network (CM-JIVNet), a unified probabilistic framework designed to learn factorized latent representations from paired SC-FC datasets. Our model utilizes a multi-head attention fusion module to capture non-linear cross-modal dependencies while isolating independent, modality-specific signals. V alidated on Human Connectome Project Y oung Adult (HCP-Y A) data, CM-JIVNet demonstrates superior performance in cross-modal reconstruction and behavioral trait prediction. By effectively disentangling joint and individual feature spaces, CM-JIVNet provides a robust, interpretable, and scalable solution for large-scale multimodal brain analysis.

Apple could unveil Gemini-powered Siri in Feb. TikTok's US joint venture is off to a bumpy start. UpScrolled is seeing a surge in interest. TikTok's newly formed US entity is off to a very bumpy start. As the app continues to face technical issues affecting the recommendation algorithm, view counts and other features, TikTok is also seeing a wave of frustrated users uninstalling it, according to new data. Analytics firm Sensor Tower, which tracks downloads and other app store-related metrics, told CNBC that there has been a 150 percent rise in uninstalls of the TikTok app in the United States compared with the last three months.

Apple could unveil Gemini-powered Siri in Feb. Plaintiffs claimed they saw ads based on conversations Google Assistant shouldn't have heard. Google has agreed to a $68 million settlement regarding claims that its voice assistant inappropriately spied on smartphone users. Plaintiffs claimed that the company's Google Assistant platform began listening to them after it misheard conversations that sounded like its wake words. The suit argued that private information that Google Assistant shouldn't have heard was then used to deliver those individuals targeted ads. The preliminary class action settlement was filed on Friday and now awaits approval from U.S. District Judge Beth Labson Freeman.

"In my opinion ICE are the bad guys. I am not proud that the company I enjoy so much working for is part of this," one worker wrote on Slack. After federal agents shot and killed Minneapolis nurse Alex Pretti on Saturday, Palantir workers pressed for answers from leadership on the company's work with Immigration and Customs Enforcement (ICE) --and many questioned whether Palantir should be involved with the agency at all. Leadership defended its work as in part improving "ICE's operational effectiveness." Internal Slack messages reviewed by WIRED reveal growing frustration within Palantir over its relationship with the Department of Homeland Security (DHS), and in particular, ICE's enforcement and investigations teams.

The technical failure coincided with TikTok's ownership transition, leading users to question whether videos criticizing ICE raids in Minnesota were being intentionally censored. TikTok is currently experiencing a widespread service outage in the US, causing disruptions for millions of users only a few days after the company officially transferred control of its American business to a group of majority-US investors . The technical issues led many TikTok users to speculate about whether the app's new owners were intentionally suppressing videos about political topics, particularly content related to recent federal immigration operations in Minnesota. TikTok has denied the allegations, attributing the problems to a power outage. TikTok users began reporting on Sunday that they were having trouble uploading videos to the app as well as viewing content that had already been posted on the platform.

Hazrat Mirza Ghulam Ahmad, also known as the Promised Messiah and the Imam Mahdi, wrote a 1905 poem describing massive earthquakes and destruction across the world, which some have now interpreted as a warning of World War III . In the poem, published around the time of his death in 1908, Ahmad predicted streams of blood flowing from widespread death, entire regions being wiped out, a massive earthquake, and even strange sky events beyond scientific explanation. It mentions of calamity befalling the Czar of Russia has been seen by some as foreshadowing modern conflicts involving Russia, such as the war in Ukraine and continued tensions with the US and NATO .

Many of today's most popular products including gels, strips, and rinses rely on peroxide-based bleaching solutions. While effective, the chemical processes generate reactive oxygen species (ROS) compounds that not only destroy staining molecules--they can eventually erode tooth enamel .
