In recent decades, caving has changed considerably due to the availability of modern protective wear and equipment.

In recent decades, at least two continuations of this fragment have appeared:

In recent decades the Cyclades islands have become popular with European and other tourists, and as a result there have been problems with erosion, pollution, and water shortages.

Cheerleading's increasing popularity in recent decades has made it a prominent feature in high-school themed movies and television shows.

Canada has witnessed a " Celtic revival " in which many Maritime musicians and songs have risen to prominence in recent decades.

Regional transportation networks have also changed significantly in recent decades with port modernizations, with new expressways and ongoing arterial highway construction, the abandonment of various low-capacity railway branchlines ( including the entire railway system of Prince Edward Island and southwestern Nova Scotia ), and the construction of the Canso Causeway and the Confederation Bridge.

The Chabad-Lubavitch branch of Hasidic Judaism has been an exception to this non-proselytizing standard, since in recent decades it has been actively promoting Noahide Laws for Gentiles as an alternative to Christianity.

In recent decades, de Pizan's work has been returned to prominence by the efforts of scholars such as Charity Cannon Willard, Earl Jeffrey Richards and Simone de Beauvoir.

Chiropractic has developed a strong political base and sustained demand for services ; in recent decades, it has gained more legitimacy and greater acceptance among medical physicians and health plans in the U. S., and the principles of evidence-based medicine have been used to review research studies and generate practice guidelines.

Most quantitative calculations in modern quantum chemistry use either valence bond or molecular orbital theory as a starting point, although a third approach, Density Functional Theory, has become increasingly popular in recent years.

Its necessity arises from the well-known fact that apart from relatively recent results concerning the hydrogen molecular ion ( see references therein for more details ), the quantum n-body problem cannot be solved analytically, much less in closed form.

In recent years, however, doubt has been cast on EPR's conclusion due to developments in understanding locality and especially quantum decoherence.

Historically, classical mechanics came first, while quantum mechanics is a comparatively recent invention.

There have been recent claims that loop quantum gravity may be able to reproduce features resembling the Standard Model.

In recent years, it has consisted primarily of quantum chemistry, i. e., the application of quantum mechanics to problems in chemistry.

A more recent paper by Carlos Barceló, Stefano Finazzi, and Stefano Liberati makes use of quantum theory to argue that the Alcubierre Drive at FTL velocities is impossible ; mostly due to extremely high temperatures caused by Hawking radiation destroying anything inside the bubble at superluminal velocities and leading to instability of the bubble itself.

One recent significant development here is the introduction of a quantum group, a certain kind of Hopf algebra.

A recent development called non-relativistic quantum electrodynamics ( NRQED ) used this system as a proving ground.

Most physicists consider his overall approach to be unsuccessful. Attempts by recent scientists to develop a unified theory focus on the development of a quantum theory that includes gravitation.

Kauffman's recent work translates his biological findings to the mind body problem and issues in neuroscience, proposing attributes of a new " poised realm " that hovers indefinitely between quantum coherence and classicality.

While there has been a recent proposal relating to observation of naked singularities, and doubly special relativity, as a part of a program called loop quantum cosmology, as of now there is no experimental observation for which loop quantum gravity makes a prediction not made by the Standard Model or general relativity ( a problem that plagues all current theories of quantum gravity ).

More recent developments in OLED architecture improves quantum efficiency ( up to 19 %) by using a graded heterojunction.

More recent experiments prove the quantum nature of molecules with a mass up to 6910 amu.

More modern proponents such as the Maharishi Mahesh Yogi have also tried to correlate recent developments from quantum physics and consciousness research with Hindu concepts.

In recent years, Borcherds has been attempting to construct quantum field theory in a mathematically rigorous manner.

" He had told me about the relatively recent discovery at Cambridge of the manner in which an electron's energy increases and decreases ... not linearly as had been long assumed, but in a discrete step, known as a " quantum ".

A recent overview of quantum turbulence is given by Skrbek.

Interest in this " old-quantum-theory " paper subsided with the arrival of full quantum mechanics, but Philp M. Morse's biography states that " in recent years it has been recognized that the correct ideas in the article are those of Slater.

In his epilogue Gribbin touches on the most recent developments of string theory at the time of writing, and introduces the transactional interpretation of quantum mechanics as the new " mythology " of our time.

Interest in Einstein – Cartan theory has been renewed in recent years, however, as theorists try to incorporate torsion into novel quantum theories or as they explore its cosmological implications.
