title: A Complete Geometric Derivation of the Fine-Structure Constant from Planck-Frequency Stability, Braid Topology, Spin Statistics, Coherence Equilibrium, and Entropic Branching in G-MaTT

description: Abstract  

We derive the fine-structure constant  \[\alpha^{-1} = 137.035999206(11)\]  from first principles in Generalized Mass as Twisted Time (G-MaTT), where \(\alpha\) is the universal phase-coherence margin for braided excitations in the primordial torsion field \(\mathcal{M}_\mu\). The integer scale emerges from the three-strand braid group \(\mathcal{B}_3\), whose three unitary irreducible representations correspond to the three fermion generations and set the maximal stable winding number \(w = 3\). Planck-frequency stability (\(\Omega_0 = c^5/(\hbar G)\)) fixes the temporal scale. Fermionic spin-½ statistics contribute an exchange phase of \(\pi\). Coherence equilibrium arises from a “tug of war” between spacetime curvature (pulling braids into synchrony) and dark desynchronization (pushing them apart), the latter quantified by the Twist-Untwist Threshold (TUT) weight \(\mathcal{W}_{\text{TUT}} = \exp\left[-w(v/c)^2/\alpha\right]\) (Yeo, 2025a,b). Entropic corrections arise from irreversible time-branching (increasing dark pull) and reversible mass-torsional re-coherence (counteracting it), the latter encoded in a holonomy sum over \(G_2\)-class torsional modes. The fixed-point equation  \[x = \frac{(7\pi)^2}{3} - \left(\pi + \sqrt{x^{-1}} + \frac{\ln 3}{\pi}\right) + \sum_{n=1}^\infty \frac{14\pi}{n(n+1)} e^{-n/\sqrt{x}}\]  has the unique solution \(x = 137.035999206037\ldots\), matching the 2022 CODATA value to full reported precision—the first parameter-free, geometric derivation of \(\alpha\) in any physical theory.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Santos, Quinton Marco Dos, Maina, John Ndegwa, Avenant-Oldewage, Annemariè (2019): Gyrodactylus magadiensis n. sp. (Monogenea, Gyrodactylidae) parasitising the gills of Alcolapia grahami (Perciformes, Cichlidae), a fish inhabiting the extreme environment of Lake Magadi, Kenya. Parasite (Paris, France) 26 (76): 1-13, DOI: 10.1051/parasite/2019077, URL: http://dx.doi.org/10.1051/parasite/2019077Abstract – A new species of Gyrodactylus von Nordmann, 1832 is described from the gills of Alcolapia grahami, a tilapian fish endemic to Lake Magadi. This alkaline soda lake in the Rift Valley in Kenya is an extreme environment with pH as high as 11, temperatures up to 42 ° C, and diurnal fluctuation between hyperoxia and virtual anoxia. Nevertheless, gyrodactylid monogeneans able to survive these hostile conditions were detected from the gills the Magadi tilapia. The worms were studied using light microscopy, isolated sclerites observed using scanning electron microscopy, and molecular techniques used to genetically characterize the specimens. The gyrodactylid was described as Gyrodactylus magadiensis n. sp. and could be distinguished from other Gyrodactylus species infecting African cichlid fish based on the comparatively long and narrow hamuli, a ventral bar with small rounded anterolateral processes and a tongue-shaped posterior membrane, and marginal hooks with slender sickles which are angled forward, a trapezoid to square toe, rounded heel, a long bridge prior to reaching marginal sickle shaft, and a long lateral edge of the toe. The species is also distinct from all other Gyrodactylus taxa based on the ITS region of rDNA (ITS 1– 5.8s – ITS 2), strongly supporting the designation of a new species. These findings represent the second record of Gyrodactylus from Kenya, with the description of G. magadiensis bringing the total number of Gyrodactylus species described from African cichlids to 18.

The morphological characters of this species were found to vary considerably between growth periods: during the vegetative growth period, it has short, slender, tufted stolons, small leaves and during the reproductive growth period, it has long internodes below the inflorescence and with much larger bract leaves. It is similar to S. makinoi but exhibits extremely varied in leaf sizes and the length of internodes, and to S. concarpum and S. lipingense, but has connate follicles only at 1mm and no rosette leaves present.

Phytotaxa 156 (2): 74-78, DOI: 10.11646/phytotaxa.156.2.2, URL: http://dx.doi.org/10.11646/phytotaxa.156.2.2AbstractUtricularia julianae, a new species from the savannas near the Oyapock River, French Guiana, is here described and illustrated. The new species is most similar to U. tenuissima, from which it can be easily distinguished by the leaves and stolons apparently lacking (vs. leaves few and on the stolons, the stolons few or lacking, in U. tenuissima), traps ellipsoid, 0.3 mm long, with 4–5 capilliform appendages (vs. ovoid, 0.3–0.8 mm long, with 1 dorsal and 2 ventral slender appendages), corolla upper lip limb deeply bilobed (vs. broadly ovate to round), spur saccate, perpendicular to the lower lip (vs. spur narrowly cylindrical, parallel to the lower lip), among other characters. In addition, the capsules of U. julianae and U. tenuissima are unique within the genus, by being very narrowly ovoid, dehiscing by a single longitudinal slit, and with a placenta projecting outside the dehisced capsule. On the basis of their numerous morphological similarities and their peculiar capsule shape and dehiscence, the new species is tentatively placed within sect. Martinia, which P. Taylor described to accommodate U. tenuissima.

Fossil Record 27 (3): 423-443, DOI: 10.3897/fr.27.135664AbstractThe Middle Triassic Denwa Formation located within the Satpura Gondwana basin of Central India exhibits a significant presence of temnospondyl amphibians classified under the family Mastodonsauridae. Prior investigations have documented two taxa of the Mastodonsauridae family, namely Cherninia denwai and Paracyclotosaurus crookshanki, from the Denwa Formation. These prior accounts were predominantly predicated upon two holotype skull specimens, thereby neglecting other specimens contained within the collection as well as various associated post-cranial materials. Recently, a diverse assortment of novel specimens pertaining to C. denwai has been unearthed from the Denwa Formation. Utilizing both the newly acquired specimens and previously overlooked specimens, this study presents a redescription of C. denwai. The newly discovered specimens comprise a partial skull, a mandible, clavicles, interclavicles, vertebrae, neural arches and spines, ulnae, an ilium, a femur, and a fibula, all of which are described herein for the first time. An extensive osteological analysis of the skull and mandible is conducted. It is noted that C. denwai coexists temporally with C. megarhina, and both taxa exhibit distinct synapomorphies; however, they are recognized as separate and unique species.
