Ethiopian girl reportedly guarded by lions
A 12-year-old girl who was abducted and beaten by several men was found being guarded by three lions who apparently had chased off her captors, a policeman said Tuesday.

Basis Expansion Extrapolation based Long-Term Channel Prediction for Massive MIMO OTFS Systems
Massive multi-input multi-output (MIMO) combined with orthogonal time frequency space (OTFS) modulation has emerged as a promising technique for high-mobility scenarios. However, its performance could be severely degraded due to channel aging caused by user mobility and high processing latency. In this paper, an integrated scheme of uplink (UL) channel estimation and downlink (DL) channel prediction is proposed to alleviate channel aging in time division duplex (TDD) massive MIMO-OTFS systems. …

JD Vance is being lambasted for dismissing social safety net rollbacks under the Trump tax bill currently making its way through Congress.
On Monday night, Vance attempted to rally support for the bill in a post on X, writing,
“Everything else—the CBO score [the Congressional Budget Office cost estimate], the proper baseline, the minutiae of the Medicaid policy—is immaterial compared to the ICE money and immigration enforcement provisions.”
Many were rubbed the wrong way by…

Backpressure-based Mean-field Type Game for Scheduling in Multi-Hop Wireless Sensor Networks
We propose a Mean-Field Type Game (MFTG) framework for effective scheduling in multi-hop wireless sensor networks (WSNs) using backpressure as a performance criterion. Traditional backpressure algorithms leverage queue differentials to regulate data flow and maintain network stability. In this work, we extend the backpressure framework by incorporating a mean-field term into the cost functional, capturing the global behavior of the system alongside local dynamics. The resulting model utilizes t…

Bundestagspräsidentin #Klöckner hat ihr Amt immer noch nicht verstanden (mich wundert es nicht). Sie agiert immer noch aus einem CDU Mindset heraus.
Nach Lammert, Schäuble und Bas ist Klöckner eine ganz, ganz herbe Enttäuschung. Wie kann man nur mit so wenig Format das 2. höchste Amt in Deutschland bekommen?
Frau Klöckner, lassen Sie sich von Ihren VorgängerInnen erklären, wie man sic…

Moskau meldet erneuten Austausch von Gefangenen
Russland und die Ukraine haben nach Angaben aus Moskau erneut Gefangene ausgetauscht. Man habe im Gegenzug eine Gruppe ukrainischer Soldaten übergeben, teilte das Verteidigungsministerium in Moskau mit. Angaben zur Zahl der ausgetauschten Soldaten machte es nicht. Die ukrainische Regierung gab zunächst keinerlei Stellungnahme ab.
Die beiden Kriegsparteien haben in der Vergangen…

System-performance and cost modeling of Large Language Model training and inference
Large language models (LLMs), based on transformer architectures, have revolutionized numerous domains within artificial intelligence, science, and engineering due to their exceptional scalability and adaptability. However, the exponential growth in LLM size and complexity has outpaced advancements in compute capacity, memory bandwidth, network performance, and cost efficiency, posing significant challenges to their scalability on distributed systems. To address these limitations, alternative m…
