Intercellular cancer collisions generate an ejected crystal comet tail effect with fractal interface embryoid body reassembly transformation
We have documented self-assembled geometric triangular chiral crystal complexes (GTCHC) and a framework of collagen vascular invariant geometric attractors in cancer tissues. This article shows how this system evolves in time. These structures are incorporated together and evolve in different ways. When the geometric core is stable, and the tissue architecture collapses, fragmented components emerge, which reveal a hidden interior identifying how each molecule is reassembled into the original mold, using one common connection, ie, a fractal self-similarity that guided the system from the beginning. GTCHC complexes generate ejected crystal comet tail effects and produce strange helicity states that arise in the form of spin domain interactions. As the crystal growth vibration stage progresses, biofractal echo images converge in a master-built construction of embryoid bodies with enolase-selective immunopositivity in relation to clusters of triangular chiral cell organization. In our electro-optic collision model, we were able to predict and replicate all the characteristics of this complex geometry that connects a physical phenomenon with the signal patterns that generate biologic chaos. Intrinsically, fractal geometry makes spatial correction errors embrace the chaotic system in a way that permits new structures to emerge, and as a result, an ordered self-assembly of embryoid bodies with neural differentiation at the final stage of cancer development is a predictable process. We hope that further investigation of these structures will lead not only to a new way of thinking about physics and biology, but also to a rewarding area in cancer research
Characterisation of AMS H35 HV-CMOS monolithic active pixel sensor prototypes for HEP applications
Monolithic active pixel sensors produced in High Voltage CMOS (HV-CMOS)
technology are being considered for High Energy Physics applications due to the
ease of production and the reduced costs. Such technology is especially
appealing when large areas to be covered and material budget are concerned.
This is the case of the outermost pixel layers of the future ATLAS tracking
detector for the HL-LHC. For experiments at hadron colliders, radiation
hardness is a key requirement which is not fulfilled by standard CMOS sensor
designs that collect charge by diffusion. This issue has been addressed by
depleted active pixel sensors in which electronics are embedded into a large
deep implantation ensuring uniform charge collection by drift. Very first small
prototypes of hybrid depleted active pixel sensors have already shown a
radiation hardness compatible with the ATLAS requirements. Nevertheless, to
compete with the present hybrid solutions a further reduction in costs
achievable by a fully monolithic design is desirable. The H35DEMO is a large
electrode full reticle demonstrator chip produced in AMS 350 nm HV-CMOS
technology by the collaboration of Karlsruher Institut f\"ur Technologie (KIT),
Institut de F\'isica d'Altes Energies (IFAE), University of Liverpool and
University of Geneva. It includes two large monolithic pixel matrices which can
be operated standalone. One of these two matrices has been characterised at
beam test before and after irradiation with protons and neutrons. Results
demonstrated the feasibility of producing radiation hard large area fully
monolithic pixel sensors in HV-CMOS technology. H35DEMO chips with a substrate
resistivity of 200 cm irradiated with neutrons showed a radiation
hardness up to a fluence of ncm with a hit efficiency of
about 99% and a noise occupancy lower than hits in a LHC bunch
crossing of 25ns at 150V
Estudio fitoquÃmico de JunÃperus Oxycedrus, L. subsp. Macrocarpa
Se han estudiado los componentes ácidos de las arcésticas de Juniperus oxycedrus L. subsp. macrocarpa, encontrándose fundamentalmente ácidos diterpénicos de esqueleto labdano; trans-comúnico (mayoritario), mirceocomúnico, cis-comúnico, junicédrico, 15-metil-imbricatálico, 12(R)-hidroximirceocomúnico, imbricatólico e isocuprésico. También se han identificado los ácidos sandaracopimárico e isopimárico, con esqueleto pimarano y el abietano, éter metÃlico de sugiol. Este estudio ha permitido establecer las analogÃas y diferencias fitoquÃmicas con la subespecie oxycedrus, asà como su quimiotaxonomÃa dentro del género JunÃperus.Acid components from berries of Juniperus oxycedrus L. subsp. macrocarpa, have been studied.

A test-rig to evaluate a dual-3-phase induction motor drive
The potential advantages of multi-phase solutions over
the conventional 3-phase ones have been widely
described in the literature. However, their feasibilities
and performances have been poorly described and
proven. The main goal of this paper is the design and
implementation of a test rig to evaluate some control
policies for a double-3-phase induction motor drive, a
multiphase drive with interest in Electric Vehicle (EV)
applications

We studied the essential oil of Lavandula Lanata Boiss, in which thirty four substances were identified, camphor, lavandulol and 3-octanone being the most abundant of them.
