Inproclaiming this Decade, the international community is recognizing that people of African descent represent a distinct group whose human rights must be promoted and protected. Around 200 million people identifying themselves as being of African descent live in the Americas. Many millions more live in other parts of the world, outside of the African continent.
Descent is a noun that means the act of moving downward (descending), a downward movement, or downward movement in general. Dissent can be a noun meaning disagreement, as in I voiced my dissent, or a verb meaning to disagree, as in The judge is expected to dissent. Decent is an adjective that means adequate or suitable, as in a decent meal, or good or respectable, as in a decent person.
Despite their similar spelling, descent and decent are pronounced differently. In descent, the emphasis is on the -scent part of the word, with the first part pronounced like dih. In decent, the emphasis is on the first part of the word, which is pronounced like dee.
Having a rescue plan is only part of providing fast, secure fallen user rescues; the right equipment and personnel are just as important. FallTech products are designed for both self and assisted rescues that require stable, controlled descents. For high levels of protection, we build each component to stringent standards for safety, versatility, and dependability. Our solutions are durably built and configured to perform in virtually any construction or industry rescue operation.
Transmissions within and across artworks and artists reverberate throughout the gallery as unexpected genealogies and unruly inheritance. This exhibition considers the aesthetic, sensory, and social horizons that emerge when we dissent from traditional lines of descent.

Her work has been exhibited at Artists Space, New York; Museum of Contemporary Art Santa Barbara; LAXART, Los Angeles; New Museum of Contemporary Art, New York; and Temple Bar Gallery + Studios, Dublin, among others. Her recent book, Lisa Tan: Sunsets, Notes from Underground, Waves, is published by Archive Books, Berlin.
Descent animates alternative modes and materials of inheritance across generations of families, artists, and artworks. While inheritance, influence, and other acts of transmission often move down vertical lines of property and patrimony, the works in this exhibition unsettle this passage with forms of heredity that are often undervalued or unconventional: used or surplus possessions, intergenerational collaborations, maternal memories and matter, transatlantic journeys, spoken words, and sound waves.
We study accelerated mirror descent dynamics in continuous and discrete time. Combining the original continuous-time motivation of mirror descent with a recent ODE interpretation of Nesterov's accelerated method, we propose a family of continuous-time descent dynamics for convex functions with Lipschitz gradients, such that the solution trajectories are guaranteed to converge to the optimum at a $O(1/t^2)$ rate. We then show that a large family of first-order accelerated methods can be obtained as a discretization of the ODE, and these methods converge at a $O(1/k^2)$ rate. This connection between accelerated mirror descent and the ODE provides an intuitive approach to the design and analysis of accelerated first-order algorithms.

I have recently come across PEG parsers, and Guido van Rossum's article on PEG parsers and how to construct them. That article talks about "PEG" parsers but internally it looks exactly like a recursive descent parser (generator). I have a feeling that that PEG parsers have something to do with generating recursive descent parsers, but am not sure.
Bryan Ford (the creator of PEG) in his 2004 article describes the first two, but the first point is not a novel contribution. Rather, PEG is equivalent to top-down parsing language (TDPL) from the 1970s in terms of expressive power, but Ford borrows convenient aspects of EBNF and regular expression syntax to make grammars easier to read and write than the extremely minimal TDPL. Basically, PEG's notation makes TDPL more approachable, like writing code in C or Python instead of Assembly.
In Ford's 2002 article based on his master's thesis, he also introduces the Packrat parsing algorithm which allows recursive descent parsers, even those with infinite lookahead like PEG, to run in linear time by memoizing, or caching, intermediate results. This is a theoretical result, however, and even if it helps with some pathological cases, in many cases the overhead of Packrat's memoization is significant. Parsing with PEGs without Packrat parsing is simply recursive descent parsing.
One interesting thing about PEG's formal properties, compared to CFGs, is the prioritized choice operator (PEG notation uses / instead of EBNF's for ambiguous choice). With prioritized choice, alternatives are attempted in order, and once an alternative succeeds, the others will not be attempted. Thus, a PEG, unlike a context-free grammar (CFG), is unambiguous; there is either one parse for an input, or no parses. Relatedly, PEGs are considered "analytical" grammars rather than "generative" grammars (e.g., CFG, which has its roots in linguistics for describing natural language utterances) as their purpose is for parsing rather than licensing (or generating) valid strings.
You don't really choose between PEG parsing and recursive descent parsing as they are about the same thing, but you may choose to use a PEG parsing library to implement your parser via a grammar instead of hand-writing the parsing functions. As Michael Dyck commented, however, PEGs are a subset of recursive descent parsers as you can write recursive descent parsers that go beyond what's representable in a PEG. Then again, many PEG libraries extend the original formalism with features such as semantic actions or additional syntactic constructs.
From the point of view of infinity category theory (nPOV), descent is the study of generalizations of the sheaf condition on presheaves to presheaves with values in higher categories. Those higher presheaves that satisfy descent are called infinity-stacks.
For SS any small category and Set the category of small sets, write PSh(S)=[S op,Set]\mathrmPSh(S) = [S^op, Set] for the category of presheaves on SS. Categories of this form enjoy various nice properties which are familiar from SetSet itself, and which are summarized by saying that PSh(S)\mathrmPSh(S) is a topos. The relevance of this for the present purpose is that there is a natural notion of morphisms of topoi, which are functors respecting this structure in some sense: these are called geometric morphisms.
Recall from model structure on simplicial presheaves that there is the global and the local injective simplicial model structure on [S op,SSet][S^op, SSet] which makes it a simplicial model category and that the local model structure is a (Bousfield-)localization of the global model structure.
Since for instance something as simple as an abelian group AA regarded as a complex of groups in degree nn (hence as an nn-group) already bcomes a somewhat involved object to understand under the nervet operation,
The ATC must have changed since the last time I used it as it never used to take you to cruise level. Usually you would get asked to climb to somewhere in the 12 to 15 thousand feet range and that would be it. You would then have to request step climbs up to your cruise alt.
I had much the same problem with a late descent. That along with the constant requests to change frequencies got to me, so I changed the way I fly longer IFR flights. I let ATC handle my flight from clearance until I get to cruise altitude, then I cancel IFR, which allows me to fly without interruptions.
The reason why ATC is late in giving descent instructions is because it is doing exactly what is in the flight plan. If the cruising altitude is 39,000 ft and your flight plan is imported from SimBrief, then your flight plan tells ATC to keep you at your cruising altitude until the IAF. ATC instructions are linked directly to the flight plan information.
Create the flight plan using the MSFS World Map flight planner. When a flight plan is created in MSFS using SIDs, STARs, and approaches, the flight plan contains the necessary information about the correct waypoint altitude and speed restrictions needed by ATC. (Imported flight plans are missing this information needed by ATC.)
The workaround provided by SimBrief is to reselect the arrival and approach using the drop down boxes right after import. MSFS will then insert the correct waypoint information into the flight plan. I do this for every flight plan I import. I then save the flight plan with the MSFS information in case I want to fly it again.
