Research expedition faces extreme conditions in fast-changing Arctic
Research expedition extreme conditions fast-changing Arctic
2020/4/29
In October 2019, scientists froze a ship filled with equipment into Arctic sea ice with the intention of drifting across the Arctic Ocean for a full year, gathering data on polar atmosphere, ice and o...

In October 2019, scientists froze a ship filled with equipment into Arctic sea ice with the intention of drifting across the Arctic Ocean for a full year, gathering data on polar atmosphere, ic...
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...
Men and women show equal ability at recognizing faces
Men women equal ability recognizing faces
2017/7/20
Despite conventional wisdom that suggests women are better than men at facial recognition, Penn State psychologists found no difference between men and women in their ability to recognize faces and ca...
Fixating on Faces
Fixating Faces
2017/2/16
When we are walking down a crowded street, our brains are constantly active, processing a myriad of visual stimuli. Faces are particularly important social stimuli, and, indeed, the human brain has ne...
COUNTING THE FACES OF RANDOMLY-PROJECTED HYPERCUBES AND ORTHANTS, WITH APPLICATIONS
RANDOMLY-PROJECTED ORTHANTS
2015/8/21
Let RN
+ denote the positive orthant; the expected number of k-faces of
the random cone ARN
+ obeys Efk(ARN
+)/fk(RN
+) = 1 − PN−n,N−k. The
formula applies to numerous matrix e...
COUNTING FACES OF RANDOMLY-PROJECTED POLYTOPES WHEN THE PROJECTION RADICALLY LOWERS DIMENSION
RANDOMLY-PROJECTED RADICALLY LOWERS DIMENSION
2015/8/21
The modern trend in statistics and probability is to consider the case where both
the number of dimensions d and the sample size n are large [19, 21]. In that case, the
intuition fostered by the cla...
FEASIBILITY AND PROBLEMS OF TLS IN MODELING ROCK FACES FOR HAZARD MAPPING
Terrestrial Laser Scanning Landslides Geology Monitoring Hazard Mapping
2015/8/13
In the paper we focus on the application of TLS to carry out the geometric surveying of rock faces to derive their DSM for
simulating possible paths of falling rocks and then drawing hazard maps. Af...
Duality of non-exposed faces
convex body polar conjugate face non-exposed point singular point dual self-dual
2011/9/5
Abstract: The assignment of the conjugate face is a natural mapping associated to a convex body and its polar convex body. We study its restriction to non-exposed faces. Conjugate faces of non-exposed...
Exposed faces for decomposable positive linear maps arising from completely positive maps
decomposable positive maps exposed faces product vectors
2011/7/25
Abstract: Let $D$ be a space of $2\times n$ matrices. Then the face of the cone of all completely positive maps from $M_2$ into $M_n$ given by $D$ is an exposed face of the bigger cone of all decompos...
Oxford University scientists are using brain-scanning technology to understand how we learn to recognise and ‘read’ faces as children. The research will also investigate whether there are any differen...
APPLICATION OF TLS FOR CHANGE DETECTION IN ROCK FACES
Change Detection Deformation Monitoring Natural Hazards Rockfall Terrestrial Laser Scanning
2016/2/29
The paper describes some experiences carried out in monitoring of two rock faces in Italian Prealps in order to detect changes due to
rock detachments. Since the forecasting of possible rockfall eve...

Individual management of the animal is the first step towards reaching the goal of precision livestock farming that aids animal welfare. Accurate recognition of each individual animal is important for...
Vicinal Faces on Synthetic Goethite Observed by Atomic Force Microscopy
Atomic Force Microscopy Crystal Growth Goethite
2011/12/27
Abstract: In this paper atomic force microscopy-studies are reported suggesting the existence of vicinal faces on the (100) plane of artificially grown goethite. Goethite crystals are commonly regarde...
