Clinical Reasoning: A 50-Year-Old Man With Intracerebral Hemorrhage and Tortuous Retinal Arterioles

Posted by in categories: biotech/medical, neuroscience

A 50-year-old man presented with headache. Examination showed left sided ataxic hemiparesis and elevated blood pressure. Brain imaging revealed an acute intracerebral hemorrhage in the right lentiform nucleus, deep and periventricular white matter hyperintensities, and predominantly deep cerebral microbleeds. Fundus examination showed important arteriolar tortuosity involving several blood vessels. In this young patient, we explain the diagnostic approach to intracerebral hemorrhage, the causes of cerebral small vessel disease, and the interpretation of biomolecular tests.

Higher-order topological simulation unlocks new potential in quantum computers

Posted by in categories: computing, engineering, quantum physics

Prof Lee said, “Existing breakthrough studies in quantum advantage are limited to highly-specific tailored problems. Finding new applications for which quantum computers provide unique advantages is the central motivation of our work.”

“Our approach allows us to explore the intricate signatures of topological materials on quantum computers with a level of precision that was previously unattainable, even for hypothetical materials existing in four dimensions,” added Prof Lee.

Despite the limitations of current noisy intermediate-scale quantum (NISQ) devices, the team is able to measure topological state dynamics and protected mid-gap spectra of higher-order topological lattices with unprecedented accuracy, thanks to advanced in-house developed error mitigation techniques. This advance demonstrates the potential of current quantum technology to explore new frontiers in material engineering.

Strong interlayer magnetic exchange coupling in La3Ni2O7-δ revealed by inelastic neutron scattering

Posted by in category: futurism

Recently, an inelastic neutron scattering work on the bilayer nickelate La3Ni2O7-δ polycrystal finished by a team from Sun Yat-sen University was published in Science Bulletin. The team employed neutron spectroscopy to study the magnetic ground state and spin dynamics of La3Ni2O7-δ at ambient pressure.

General Dynamics secures $491 million contract extension from Space Development Agency

Posted by in categories: military, satellites

WASHINGTON — General Dynamics Mission Systems, a unit of defense contractor General Dynamics, has been awarded a $491 million contract extension by the Space Development Agency for satellite ground systems, the Pentagon announced Aug. 30.

The modification nearly doubles the company’s existing contract with the Space Development Agency (SDA) to approximately $900 million through 2029. General Dynamics in 2022 was selected to build the ground operations and integration segment for the SDA’s Proliferated Warfighter Space Architecture (PWSA), a mesh network of satellites in low Earth orbit designed to support global military operations.

SDA. which is under the U.S. Space Force, is building the PWSA with a dedicated tracking layer that allows for real-time detection and monitoring of ballistic missile threats. The PWSA also is intended to provide a low-latency communication backbone for continuous data transmission, enhancing the ability to coordinate joint operations across different military branches.

Chinese researchers assess U.S. space situational awareness, call for boost in China’s capabilities

Posted by in categories: satellites, surveillance

HELSINKI — Chinese researchers are calling for improved space situational awareness, following an assessment of U.S. capabilities and trends.

An article titled “A Review of Space Situational Awareness Satellites: Silentbarker,” published in the journal ACMSR, provides an in-depth review of the development, status and future trends of space situational awareness (SSA) satellites.

It focuses in particular on four significant programs developed by the United States. These are the Midcourse Space Experiment (MSX), the Space-Based Surveillance System (SBSS), the Geosynchronous Space Situational Awareness Program (GSSAP) and Silentbarker.

New Experiment Brings The Quantum Internet a Step Closer to Reality

Posted by in categories: internet, quantum physics

While the idea of a quantum internet has a huge amount of potential, getting it hooked up to the regular old internet has its challenges.

Now a new study hints at how existing and future networks could be combined.

An experiment conducted by researchers from Leibniz University Hannover in Germany show how quantum information and the classic 1s and 0s of conventional data could be beamed down the same optical fiber.
