We report on precision resonance spectroscopy measurements of quantum states ultracold neutrons confined above the surface a horizontal mirror by gravity potential Earth. Resonant transitions between several lowest are observed for first time. These demonstrate that Newton's inverse square law is understood at micron distances an energy scale $1{0}^{\ensuremath{-}14}\text{ }\text{ }\mathrm{eV}$. At this level precision, we able to provide constraints any possible gravitylike interaction. In...
A versatile and portable magnetically shielded room with a field of (700 ± 200) pT within central volume 1 m × gradient less than 300 pT/m, achieved without any external stabilization or compensation, is described. This performance represents more hundredfold improvement the state art for two-layer magnetic shield provides an environment suitable next generation precision experiments in fundamental physics at low energies; particular, searches electric dipole moments systems tests...
We present a magnetically shielded environment with damping factor larger than 1 × 106 at the mHz frequency regime and an extremely low field gradient over extended volume. This extraordinary shielding performance represents improvement of state-of-the-art in difficult very low-frequency distortions by more order magnitude. technology enables new generation high-precision measurements fundamental physics metrology, including searches for far beyond reach accelerator-based experiments....
An increasing number of measurements in fundamental and applied physics rely on magnetically shielded environments with sub nano-Tesla residual magnetic fields. State the art rooms (MSRs) consist up to seven layers high permeability materials combination highly conductive shields. Proper equilibration is crucial obtain such low fields small gradients any MSR. Here we report a scheme equilibrate MSRs 10 times reduced duration sequence significantly lower field improved homogeneity. For search...
Introdução: A Atenção Primária à Saúde (APS) é um modelo essencial no sistema de saúde, com foco na promoção da saúde e prevenção doenças, incluindo o combate às Doenças Sexualmente Transmissíveis (DSTs). No contexto sexual reprodutiva, a APS uma estratégia crucial para melhorar acesso conscientização população sobre DSTs, promovendo comportamentos sexuais seguros detecção precoce infecções, como HIV. Diante disso, presente estudo visa explorar Básica pode transformar reduzindo incidência...
Introdução: a síndrome dos ovários policísticos (SOP) é uma das condições clínicas mais comuns entre as disfunções endócrinas que afetam mulheres em idade reprodutiva, tendo sua prevalência variando de 6% 16% dependendo da população estudada e do critério diagnóstico empregado. Caracteriza-se frequentemente por hiperandrogenismo pode se manifestar por: hirsutismo, acne, seborreia, alopecia, irregularidade menstrual, obesidade cistos ovarianos. Os fatores risco associados à SOP são...
The neutron's permanent electric dipole moment $d_n$ is constrained to below $3\times10^{-26} e~\text{cm}$ (90% C.L.) [ arXiv:hep-ex/0602020, arXiv:1509.04411 ], by experiments using ultracold neutrons (UCN). We plan improve this limit an order of magnitude or more with PanEDM, the first experiment exploiting ILL's new UCN source SuperSUN. SuperSUN expected provide a high density energies 80 neV, implying extended statistical reach respect existing sources, for that rely on long storage...

The evidence for the observation of Higgs spin-0-boson as a manifestation scalar field provides missing corner stone standard model particles (SM). However, SM fails to explain non-visible but gravitationally active part universe. Its nature is unknown confirmation giving boost scalar-field-theories. So far gravity experiments and observations performed at different distances find no deviation from Newton's law. Therefore dark energy must possess screening mechanism which suppresses...
Despite decades of reports weak magnetic field effects in biology across the tree life and on a broad range cell types, evidence to date remains met with skepticism. To remedy this, we present open-data, large-scale, varied morphological that Xenopus laevis embryo development is accelerated well-engineered, environmentally-calibrated hypomagnetic less than 1 nT. These data imply basal tadpole physiology can sense react absence Earth’s minute approximately 50 µ T. The effect significant, as...
