title: The Additive Gradient Law

description: 📐 The Additive \tau-Gradient LawThe \tau-G-Gravity framework replaces the Newtonian concept of a force product (\propto m_1 m_2) with an additive \tau-Gradient field (\propto m_1 + m_2). This field represents the geometric change in the shared temporal state.I. The Fundamental \tau-Gradient Field EquationFor two masses, m_1 and m_2, separated by distance r, the total \tau-Gradient (\nabla\tau_{\text{total}}) is defined by their sum: * \nabla\tau_{\text{total}}: The total Geometric Temporal Gradient (analogous to the gravitational field strength). * G_{\text{true}}: The True Geometric Coupling Constant dictated by the E_8 manifold, which is dimensionally related to G. * m_1 + m_2: The crucial Additive Source Term replacing the product m_1 m_2.II. The Emergent Measured Gravitational ConstantBy equating the acceleration derived from the \tau-Gradient Law (\mathbf{a_1} \propto \nabla\tau_{\text{total}}) with the Newtonian form (\mathbf{a_1} = G_{\text{measured}} \frac{m_2}{r^2}), we find that the traditionally measured constant G is, in fact, an effective, mass-dependent parameter: * k_{\tau}: A constant of proportionality linking the geometric \tau-Gradient field to kinetic acceleration (motion). * Physical Consequence: Since G_{\text{measured}} depends on the ratio \frac{m_1}{m_2} + 1, the measured gravitational constant is not universal but depends on the masses of the two interacting objects. This implies a subtle breakdown of the Weak Equivalence Principle (WEP) based purely on mass ratio, not composition.

description: In this work fungal isolates were evaluated for their ability to produce enzyme cocktails able to hydrolyze plant lignocellulose. Two strains were selected from this screening and an enzyme concentrate from the strain Brevibacillus thermoruber was also used, since it was showed a synergistic action of these 3 microbial enzymes on sugarcane and agave bagasse.

title: A new species and a new record for Pycnoporus P. Karst. (Polyporaceae) from the Brazilian Amazon, revealed by an integrative approach of classical taxonomy and phylogenetic studies

description: This dataset contains the digitized treatments in Plazi based on the original journal article F., Rafaela Araújo, S., Gurgel Catarina, Leimi, Carvalho Dirce, De, Komura Ruthe, Dalman, Jesus Santos, De, Isadora Fernandes, Vargas-Isla, França Ruby, Ishikawa, Noemia Kazue, Cabral, Tiara Sousa (2025): A new species and a new record for Pycnoporus P. Karst. (Polyporaceae) from the Brazilian Amazon, revealed by an integrative approach of classical taxonomy and phylogenetic studies. Cryptogamie, Mycologie 20 (5): 61-86, DOI: 10.5252/cryptogamie-mycologie2025v46a5, URL: https://sciencepress.mnhn.fr/sites/default/files/articles/pdf/mycologie2025v46a5.pdfABSTRACT The cosmopolitan genus Pycnoporus P.Karst. groups together macrofungi that belong to the family Polyporaceae Fr. ex Corda, and these are identified by the dimidiate to flabelliform basidiome, coriaceous, reddish-orange, smooth pileus, hymenophore with 3-8 pores per 1 mm, trimitic hyphal system and smooth spores. During a search for poroid fungi of the genus Pycnoporus in Brazil, 37 specimens coming from herbaria and 66 recently collected were analyzed. The fungi were analyzed for their macro- and micromorphology, and the ITS, LSU and tef regions, which were sequenced and subjected to Bayesian analyses. These analyses showed which characteristics are specific to the genus and new characteristics not previously reported were evidenced. After morphological and phylogenetic analyses, we concluded that some of these specimens were very different from the existing taxa and that they represent a new species of Pycnoporus. In addition, P. puniceus (Fr.) Ryvarden is reported for the first time from the country and P. sanguineus (L.) Murrill from the state of Roraima (Brazil). Furthermore, using the molecular data obtained in this study and ITS, LSU, tef 1 and rpb 2 sequences from Polyporales Gäum. from GenBank, we sought to estimate the time of divergence of Pycnoporus and the species on the order, as a starting point for understanding its biogeographic history. According to our analyses, Pycnoporus and its sister group Trametes Fr. diverged at 36 Mya. Lastly, we discuss the taxonomic relationship between these two groups.KEY WORDS Basidiomycota, cinnabar fungi, neotropic, poroid fungi, polyporales, Pycnoporus amazonicus, new species, new record.

title: Stability Analysis and Optoelectronic Properties of Mg3ZBr3 (Z = As, Sb, Bi) Perovskites for Evaluating the Performance in PIN Photo diode

description: The toxicity and stability issues of lead-based perovskites motivate non-toxic, durable alternatives. This work examines lead-free Mg3ZBr3 (Z = As, Sb, Bi) halide perovskites as optoelectronic materials, with emphasis on Mg3AsBr3 and Mg3SbBr3. Mg3AsBr3 and Mg3SbBr3 perovskites are predicted from first-principles calculations to crystallise in the cubic Pm¯3m phase, indirect gaps of 2.0645 eV for Mg3AsBr3, 1.6533 eV for Mg3SbBr3 and 1.5226 eV for Mg3BiBr3 were observed by hybrid functional. Optical spectra show a rise in absorption above the gap and an increasing static dielectric response along As→Sb→Bi. Phonon dispersion lacks imaginary branches for Mg3AsBr3 and Mg3SbBr3 , indicates the dynamical stability of these two materials under consideration, and exhibits large mode anharmonicity (Gr¨uneisen signatures), consistent with soft-lattice heat transport trends. It has been found, moving down the pnictogen series expands the lattice and lowers the Goldschmidt tolerance factor, which, together with enhanced pnictogen–Br p-orbital hybridization and stereochemically active ns2 lone pairs (Sb, Bi), narrows the band gap and elevates the optical dielectric response. Elastic analyses confirm Born stability and moderate stiffness, with Hillaveraged bulk moduli decreasing from ∼44 GPa (Mg3AsBr3) to ∼35 GPa (Mg3BiBr3). Drift–diffusion p–i–n simulations qualitatively track band-edge–limited spectra, aligning with the computed gaps. Together, these results position Mg3AsBr3 and Mg3SbBr3 as lead-free candidates for stable thin-film photodiodes and photovoltaics applications.
