Approximate dynamic programming via sum of squares programming

We describe an approximate dynamic programming method for stochastic control problems on infinite state and input spaces. The optimal value function is approximated by a linear combination of basis functions with coefficients as decision variables. By rela ...

Manifold Sparse Beamforming

Volkan Cevher, Afsaneh Asaei, Baran Gözcü

We consider the minimum variance distortionless response (MVDR) beamforming problems where the array covariance matrix is rank deficient. The conventional approach handles such rank-deficiencies via diagonal loading on the covariance matrix. In this settin ...

The interplay of conditional NCAM-knockout and chronic unpredictable stress leads to increased aggression in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht, Céline Fournier

Abstract The neural cell adhesion molecule (NCAM) is a key regulator of brain plasticity. Substantial evidence indicates that NCAM is down-regulated by exposure to sustained stress and chronic stress seems to lead to increased aggression. In addition, cons ...

Personality traits in rats predict vulnerability and resilience to developing stress-induced depression-like behaviors, HPA axis hyper-reactivity and brain changes in pERK1/2 activity

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Cristina Marquez Vega, Jorge Eduardo Castro Cifuentes, Shanaz Diessler

Emerging evidence indicates that certain behavioral traits, such as anxiety, are associated with the development of depression-like behaviors after exposure to chronic stress. However, single traits do not explain the wide variability in vulnerability to s ...

Psychobiological Vulnerability to Stress

Maria del Carmen Sandi Perez, Jorge Eduardo Castro Cifuentes

Several psychobiological factors are associated with vulnerability/resilience to stress-induced depression. Emerging evidence indicates behavioral traits, such as anxiety, can be related to depression-like symptoms after exposure to chronic stress. However ...

Coupling quantum and continuum scales to predict crack tip dislocation nucleation

William Curtin, Derek Warner

A quantum-continuum multiscale coupling of Kohn-Sham density functional theory to continuum material is presented that can handle mechanics problems in metals when long-range stress fields are present, such as occurs for dislocations and cracks. The method ...

The role of perspective functions in convexity, polyconvexity, rank-one convexity and separate convexity

Bernard Dacorogna

Any finite, separately convex, positively homogeneous function on

\mathbb{R}^2

is convex. This was first established by the first author ["Direct methods in calculus of variations", Springer-Verlag (1989)]. Here we give a new and concise proof of this re ...

Stress before puberty exerts a sex- and age-related impact on auditory and contextual fear conditioning in the rat

Maria del Carmen Sandi Perez

Adolescence is a period of major physical, hormonal, and psychological changes. It is also characterized by a significant increase in the incidence of psychopathologies and this increase is gender-specific. Stress during adolescence is associated with the ...

Analysis of cracked steel members reinforced by pre-stressed composite patch

Alain Nussbaumer, Andrea Bassetti

Pre-stress bonded composite patch is a promising technique to reinforce steel member damaged by fatigue. ifhe effectiveness of this technique was verified by fatigue tests on notched steel plates. Results showed that the application of carbon fibre reinfor ...
