Gauge origin of discrete flavor symmetries in heterotic orbifolds
We show that non-Abelian discrete symmetries in orbifold string models have a gauge origin. This can be understood when looking at the vicinity of a symmetry enhanced point in moduli space.

Background Symmetry during lifting is considered critical for allowing balanced power production and avoidance of injury. This investigation assessed the influence of elevating the heels on bilateral lower limb symmetry during loaded (50% of body weight)

Discrete Lorentz symmetry and discrete time translational symmetry
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.

Linking entanglement and discrete anomaly
In 3d Chern-Simons theory, there is a discrete one-form symmetry, whose symmetry group is isomorphic to the center of the gauge group. We study the ‘t Hooft anomaly associated to this discrete one-form symmetry in theories with generic gauge groups, A, B,

Accidental Peccei–Quinn symmetry from discrete flavour symmetry and Pati–Salam
We show how an accidental U(1) Peccei–Quinn (PQ) symmetry can arise from a discrete A4 family symmetry combined with a discrete flavour symmetry Z3×Z52, in a realistic Pati–Salam unified theory of flavour. Imposing only these discrete flavour symmetries,

Dai-Freed anomaly in the standard model and topological inflation
When we impose discrete symmetries in the standard model we have Dai-Freed global anomalies. However, interestingly if we introduce three right-handed neutrinos we can have an anomaly-free discrete Z 4 gauge symmetry.

Scotogenic A5 → A4 Dirac neutrinos with freeze-in dark matter
Radiative Dirac neutrino masses and their mixing are linked to dark matter through the non-Abelian discrete symmetry A5 of the 4-dimensional pentatope, softly broken to A4 of the 3-dimensional tetrahedron.

Anomalous discrete flavor symmetry and domain wall problem
Discrete flavor symmetry is often introduced for explaining quark/lepton masses and mixings. However, its spontaneous breaking leads to the appearance of domain walls, which is problematic for cosmology. We consider a possibility that the discrete flavor

In this paper I give a short review on the continuous, semi-discrete and discrete Burgers equations, which are featured as integrable equations that are linearisable.

Anomaly matching in the symmetry broken phase: Domain walls, CPT, and the Smith isomorphism
Symmetries in Quantum Field Theory may have 't Hooft anomalies. If the symmetry is unbroken in the vacuum, the anomaly implies a nontrivial low-energy limit, such as gapless modes or a topological field theory. If the symmetry is spontaneously broken,
