Behavior and neuropsychiatric manifestations in Angelman syndrome
Angelman syndrome has been suggested as a disease model of neurogenetic developmental condition with a specific behavioral phenotype. It is due to lack of expression of the UBE3A gene, an imprinted gene located on chromosome 15q. Here we review the main features of this phenotype, characterized by happy demeanor with prominent smiling, poorly specific laughing and general exuberance, associated with hypermotor behavior, stereotypies, and reduced behavioral adaptive skills despite proactive social contact. All these phenotypic characteristics are currently difficult to quantify and have been subject to some differences in interpretation. For example, prevalence of autistic disorder is still debated. Many of these features may occur in other syndromic or nonsyndromic forms of severe intellectual disability, but their combination, with particularly prominent laughter and smiling may be specific of Angelman syndrome. Management of problematic behaviors is primarily based on behavioral approaches, though psychoactive medication (eg, neuroleptics or antidepressants) may be required

High-dimensional coherent one-way quantum key distribution
High-dimensional quantum key distribution (QKD) offers secure communication,
with secure key rates that surpass those achievable by QKD protocols utilizing
two-dimensional encoding. However, existing high-dimensional QKD protocols
require additional experimental resources, such as multiport interferometers
and multiple detectors, thus raising the cost of practical high-dimensional
systems and limiting their use. Here, we present and analyze a novel protocol
for arbitrary-dimensional QKD, that requires only the hardware of a standard
two-dimensional system. We provide security proofs against individual attacks
and coherent attacks, setting an upper and lower bound on the secure key rates.
Then, we test the new high-dimensional protocol in a standard two-dimensional
QKD system over a 40 km fiber link. The new protocol yields a two-fold
enhancement of the secure key rate compared to the standard two-dimensional
coherent one-way protocol, without introducing any hardware modifications to
the system. This work, therefore, holds great potential to enhance the
performance of already deployed time-bin QKD systems through a software update
alone. Furthermore, its applications extend across different encoding schemes
of QKD qudits
