Observations were made that falsify planetary formation via proto-planetary disk. An alternative model is proposed. Observations that Falsify the Proto-planetary Disk/Nebular Hypothesis Model: 1. Older stars are still mislabeled by mainstream as planets/exo-planets. [1] They orbit the opposite direction their host star is rotating. [2] The backwards orbits completely falsifies any notion of a c...
Abstract We have conducted the first extensive observational survey of several deuterated species in 16 Class 0/I proto-brown dwarfs (proto-BDs) and 4 Flat/Class II brown dwarfs. Observations were obtained with IRAM 30m telescope DCO+ (3-2), DCN DNC N2D+ (3-2) lines. The DCO+/H13CO+, DCN/H13CN, DNC/HN13C ratios are comparatively higher show a narrower range than DCO+/HCO+, DCN/HCN, DNC/HNC rati...
We propose the semantic proto-role linking model, which jointly induces both predicate-specific semantic roles and predicate-general semantic proto-roles based on semantic proto-role property likelihood judgments. We use this model to empirically evaluate Dowty’s thematic proto-role linking theory.
We present results from two high–resolution hydrodynamical simulations of proto–cluster regions at z ≃ 2.1. The simulations have been compared to observational results for the socalled Spiderweb galaxy system, the core of a putative proto–cluster region at z = 2.16, found around a radio galaxy. The simulated regions have been chosen so as to form a poor cluster with M200 ≃ 10 hM⊙ (C1) and a ric...
Background: Thyroid carcinoma is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) approximately accounts for 5-10% of all thyroid carcinoma. Nowadays, it is obviously, the mutations in REarranged during transfection (RET) proto-oncogene, especially, mutations in exons 10, 11 and 16 are associated with MTC pathogenesis and occurrence. Thus, early diagnosis of MTC by mutati...
The clustering properties of clusters, galaxies and AGN as a function of redshift are briefly discussed. It appears that extremely red objects at z ∼ 1, and objects with J − K > 1.7 and photometric redshifts 2 < zphot < 4 are highly clustered, indicating that a majority of these objects constitutes the progenitors of nearby ellipticals. Similarly clustered seem luminous radio galaxies at z ∼ 1,...
We present models of the cosmological star formation and metal production history of (proto-)galaxies with varying axis ratios. More massive and/or roughly spherical systems reach the threshold-metallicity for a transition to a multi-phase interstellar medium earlier than less massive, more flattened systems. Therefore, more flattened, lower-mass systems start to form stars actively at smaller ...
The human lbc oncogene product is a guanine nucleotide exchange factor that specifically activates the Rho small GTP binding protein, thus resulting in biologically active, GTP-bound Rho, which in turn mediates actin cytoskeletal reorganization, gene transcription, and entry into the mitotic S phase. In order to elucidate the mechanism of onco-Lbc transformation, here we report that while proto...
