We use quasar absorption lines to study the physical conditions in the circumgalactic medium of redshift $z\approx 2.3$ star-forming galaxies taken from the Keck Baryonic Structure Survey (KBSS). In Turner et al. 2014 we used the pixel optical depth...
The purpose of this corrigendum is to point out that a handful of models in the original paper were computed with faulty initial structures. Using exactly the same modelling methods we have recomputed the faulty models with new initial structures. Th...
The electronic structure of Me[N(CN)$_2$]$_2$ (Me=Mn, Fe, Co, Ni, Cu) molecular magnets has been investigated using x-ray emission spectroscopy (XES) and x-ray photoelectron spectroscopy (XPS) as well as theoretical density-functional-based methods...
Angle-resolved photoemission spectroscopy (ARPES) combined with band structure calculations have shown that the layered transition metal dichalcogenide(TMD) NiTe$_2$ is a type-II Dirac semimetal. However, conflicting conclusions were reported regardi...
his concept to replace the fabric covered aircraft structures by metal sheets and reasoned that a metal sheet can also be loaded in compression if it is
I live in an apartment that was renovated from an old coffee and tea factory. In the bedroom, there’s this weird section built into the wall, cut-out exposing what looks like a metal shaft or chute ...
Metastable cation-disordered compounds have greatly expanded the synthesizable compositions of solid-state materials and drawn sharp attention among battery electrochemists. While such a strategy has been very successful in a few well-known structure...
A workpiece having a predetermined range of a composition is hot-forged to form precipitates in a metallographic structure and to be plastically deformed into a shape of a retainer, and is introduced …

Steel is an alloy of iron with about 1 percent carbon. It may also contain other elements, such as manganese. Whereas pure iron is a relatively soft metal that rusts easily, steel can be hard, tough, …
We present novel metamaterial structures based upon various planar wallpaper groups, in both hexagonal and square unit cells. An investigation of metamaterials consisting of one, two, and three unique sub-lattices with resonant frequencies in the t...
Jan 8, 2026 · Abortion – Intro & System State Old-school European death metal energy. Sharp riffing, direct structure, no modern polish excess. It carries that late-80s / early-90s underground ethos …
The nonlinear mechanical response of soft materials and slender structures is purposefully harnessed to program functions by design in soft robotic actuators, such as sequencing, amplified response, fast energy release, etc. However, typical designs...
Complex engineering problems can be modelled as optimisation problems. For instance, optimising engines, materials, components, structure, aerodynamics, navigation, control, logistics, and planning is essential in aerospace. Metaheuristics are applie...
Resistance-change random access memory (RRAM) devices are nanoscale metal-insulator-metal structures that can store information in their resistance states, namely the high resistance (HRS) and low resistance (LRS) states. They are a potential candida...
is the branch of philosophy that examines the basic structure of reality. It is traditionally seen as the study of mind-independent features of the world
Jul 12, 2021 · Metadata is data that describes other data, providing a structured reference that helps to sort and identify attributes of the information it describes.
Oct 8, 2025 · Metadata can be described as “data about data,” a structured way of describing and providing context to information so that it can be better understood, organized, and retrieved.
Sep 16, 2018 · Relational databases (most common type of database) store and provide access not only data but also metadata in a structure called data dictionary or system catalog.
I recently went through the interview process for Data Engineer role at Meta and received an offer. The process itself was structured and fair. A mix of SQL, Python, and Product Sense rounds, and I ac...
