Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Hard Lefschetz properties, complete intersections and numerical dimensions
莱夫谢茨数 性质 完整交集 数值尺寸
2023/4/19
In this talk, we discuss the positivity of complete intersections of nef classes, including sufficient and necessary characterizations of the hard Lefschetz property on a compact complex torus and the...
The strongest part of a tree lies not in its trunk or its sprawling roots, but in the walls of its microscopic cells.
Collapse of Northern California kelp forests will be hard to reverse（图）
Collapse Northern California kelp forests hard to reverse
2021/3/19
Satellite imagery shows that the area covered by kelp forests off the coast of Northern California has dropped by more than 95%, with just a few small, isolated patches of the bull kelp remaining. Spe...

NSF provides support drug discovery platform hard-to-treat cancers
2020/5/9
A new round of support will help a Purdue University-affiliated startup further develop a platform designed to create drugs for people with hard-to-treat cancers.Akanocure Pharmaceuticals, Inc., ...
Earliest look at newborns' visual cortex shows that babies are hard-wired to see faces and places（图）
Earliest newborns visual cortex shows babies hard-wired faces and places
2020/3/13
Within hours of birth, a baby's gaze is drawn to faces. Now, brain scans of newborns reveal the neurobiology underlying this behavior; in babies as young as 6 days, brains appear to be hardwired for t...
A Round-Collapse Theorem for Computationally-Sound Protocols; or, TFNP is Hard (on Average) in Pessiland
TFNP round-collapse average-case hardness
2019/6/26
This result follows from a more general theory of interactive average-case complexity, and in particular, a novel round-collapse theorem for computationally-sound protocols, analogous to Babai-Moran's...
Data-Independent Memory Hard Functions: New Attacks and Stronger Constructions
Memory Hard Function Depth-Robust Graph Sustained Space Complexity
2018/11/7
Data-Independent Memory-hard functions (iMHFs) are a key cryptographic primitive underlying the design of moderately expensive password hashing algorithms and egalitarian proofs of work that are resis...
Strongly Unforgeable Signatures Resilient to Polynomially Hard-to-Invert Leakage under Standard Assumptions
Digital signature Strong existential unforgeability Leakage-resilience
2018/11/2
A signature scheme is said to be weakly unforgeable, if it is hard to forge a signature on a message not signed before. A signature scheme is said to be strongly unforgeable, if it is hard to forge a ...
Modelling human hard palate shape with Bézier curves
Molecules hard palate forensic science anthropology
2018/3/5
People vary at most levels, from the molecular to the cognitive, and the shape of the hard palate (the bony roof of the mouth) is no exception. The patterns of variation in the hard palate are importa...
Static-Memory-Hard Functions and Nonlinear Space-Time Tradeoffs via Pebbling
memory-hard functions pebbling space-time trade-offs
2018/3/5
Pebble games were originally formulated to study time-space tradeoffs in computation, modeled by games played on directed acyclic graphs (DAGs). Close connections between pebbling and cryptography hav...

Advances continue to be made in hard x-ray, gamma-ray, neutron detectors and associated technologies for spectroscopy and imaging of these energetic photons and particles. Many types of position and e...
Harmonization of blood-based indicators of iron status: making the hard work matter
assay bias clinical bioindicator harmonization imprecision iron status reference material reference method standardization
2018/11/21
Blood-based indicators that are used in the assessment of iron status are assumed to be accurate. In practice, inaccuracies in these measurements exist and stem from bias and variability. For example,...
