Medicinering vid adhd kopplat till minskad risk att dö

Posted by in category: biotech/medical

Researchers from Karolinska Institutet have shown that there is a connection between medication against ADHD and a reduced risk of dying prematurely.


Forskare från Karolinska Institutet har visat att det finns ett samband mellan medicinering mot adhd och minskad risk för att dö i förtid. Risken för dödsfall av onaturliga orsaker, som olyckor och överdoseringar, kan minska med en fjärdedel, enligt den nya studien publicerad i JAMA.

Why AI Is Creating A Revolution In SaaS Pricing Models

Posted by in category: robotics/AI

Alvaro Morales is the co-founder and CEO of Orb, a flexible usage-based billing engine for modern software pricing models.

Many SaaS companies want to leverage AI in their products. However, since AI is so new, pricing remains volatile. Costs can drop drastically for an AI model when the next iteration is out, and many companies lower their pricing in response to a competitor launch to gain or retain market share.

In addition to the fluctuating and unpredictable model prices, AI pricing is mostly based on usage. Customer usage is usually difficult to predict, which affects the costs your product will incur if it relies on AI models.

Researchers demonstrate metasurfaces that control thermal radiation in unprecedented ways

Posted by in categories: materials, nanotechnology

Researchers with the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have experimentally demonstrated that metasurfaces (two-dimensional materials structured at the nanoscale) can precisely control the optical properties of thermal radiation generated within the metasurface itself. This pioneering work, published in Nature Nanotechnology, paves the way for creating custom light sources with unprecedented capabilities, impacting a wide array of scientific and technological applications.

Investigating nonlinear magnetohydrodynamics in an optimized, reactor-scale quasi-axisymmetric stellarator

Posted by in categories: evolution, particle physics

We use the new simulation capabilities of the extended-magnetohydrodynamic (MHD) code, M3D-C1, to investigate the nonlinear MHD properties of a reactor-scale quasisymmetric stellarator equilibrium. Our model captures the self-consistent evolution of the magnetic field, temperature, density, and flow profiles without imposing restrictions on the structure of the first. We include the effects of resistivity using a realistic temperature-dependent Spitzer model, along with a model for heat transport that captures the key physical characteristic, namely, strongly anisotropic diffusion in directions perpendicular and parallel to the magnetic field. We consider a quasi-axisymmetric, finite-pressure equilibrium that was optimized for self-consistent bootstrap current, quasi-symmetry, and energetic particle confinement. Our assessment finds that the equilibrium is highly unstable to interchange-like pressure-driven instabilities near the plasma edge. The initially unstable modes rapidly destabilize other modes in the direction of the N-fold rotational symmetry (toroidal, in this case). For this equilibrium, N = 2, meaning destabilization of a large number of even-numbered toroidal Fourier modes. Thus, field-periodicity is likely to be an important factor in the nonlinear MHD stability characteristics of optimized stellarators.
