Mm, another healthy Dad Dinner™!
(half-eaten mac & cheese that came back in one kid's lunchbox, half-eaten pancakes that came back in the other kids lunchbox, leftover vegetable samosas, and a couple of Pizza Bites that are actually pretty gross but the kid claims he's too full to eat the rest. And an apple, which is the only non-kid leftover.)

Transparenter Lenovo-Laptop im Hands-On: Ein Prototyp auf Sinnsuche
Hübsch, aber nutzlos? Lenovos transparenter Konzept-Laptop zieht auf dem MWC die Blicke auf sich. Wozu man ihn brauchen könnte, blieb beim Hands-On aber unklar.

Weak lensing combined with the kinetic Sunyaev Zel'dovich effect: A study of baryonic feedback
Extracting precise cosmology from weak lensing surveys requires modelling the non-linear matter power spectrum, which is suppressed at small scales due to baryonic feedback processes. However, hydrodynamical galaxy formation simulations make widely varying predictions for the amplitude and extent of this effect. We use measurements of Dark Energy Survey Year 3 weak lensing (WL) and Atacama Cosmology Telescope DR5 kinematic Sunyaev-Zel'dovich (kSZ) to jointly constrain cosmological and astrophys…

US embassy warns of imminent attack in Moscow by 'extremists'
The U.S. embassy in Russia warned that "extremists" had imminent plans for an attack in Moscow, hours after Russian security services said they had foiled a planned shooting at a synagogue by a cell from the Afghan arm of Islamic State.

The Thousand Faces of Pythagoras (As Mil Faces de Pitágoras)
The Pythagorean Theorem is one of the oldest, more famous and more useful theorems of Mathematics, and possibly the one that has had the most impact in the evolution of this and other sciences. In this article, we look at it from different perpectives, some of them uncommon. We recall some of its history, some well known applications and generalizations, other less known ones, and show it still has many surprising facets which are usually ignored. (O Teorema de Pitágoras (TP) é um dos mais …

The Simons Observatory: Design, integration, and testing of the small aperture telescopes
The Simons Observatory (SO) is a cosmic microwave background (CMB) survey experiment that includes small-aperture telescopes (SATs) observing from an altitude of 5,200 m in the Atacama Desert in Chile. The SO SATs will cover six spectral bands between 27 and 280 GHz to search for primordial B-modes to a sensitivity of $σ(r)=0.002$, with quantified systematic errors well below this value. Each SAT is a self-contained cryogenic telescope with a 35$^\circ$ field of view, 42 cm diameter optical ap…

NP-Completeness for the Space-Optimality of Double-Array Tries
Indexing a set of strings for prefix search or membership queries is a fundamental task with many applications such as information retrieval or database systems. A classic abstract data type for modelling such an index is a trie. Due to the fundamental nature of this problem, it has sparked much interest, leading to a variety of trie implementations with different characteristics. A trie implementation that has been well-used in practice is the double-array (trie) consisting of merely two integ…

High-energy extension of the gamma-ray band observable with an electron-tracking Compton camera
Although the MeV gamma-ray band is a promising energy-band window in astrophysics, the current situation of MeV gamma-ray astronomy significantly lags behind those of the other energy bands in angular resolution and sensitivity. An electron-tracking Compton camera (ETCC), a next-generation MeV detector, is expected to revolutionize the situation. An ETCC tracks each Compton-recoil electron with a gaseous electron tracker and determines the incoming direction of each gamma-ray photon; thus, it h…
