Abstract Observations indicate the Atlantic Meridional Overturning Circulation-a fundamental component of ocean’s global conveyor belt-is weakening. Although causes remain uncertain, such weakening is consistent with increasing greenhouse gases. Recent studies also suggest that anthropogenic emissions associated air pollution can impact Circulation. Here, we use four state-of-the-art chemistry-...

Cascading blackouts can be thought of as initiating events followed by propagating events that progressively weaken the power system. We briefly discuss the implications for assessing cascading risk by proper sampling from the various sources of uncertainty and for mitigating cascading risk by reducing both the initiating events and their propagation.

Although the cosmic concordance cosmology is quite successfull in fitting data, fine tuning and coincidence problems apparently weaken it. We review several possibilities to ease its problems, by considering various kinds of dynamical Dark Energy and possibly its coupling to Dark Matter, trying to set observational limits on Dark Energy state equation and coupling.

Through some topics on knowing something, empirical temperature and robot’s recognition, we make the interface between parts and whole manifesting, and express it as “extended pain”. By formalizing wholeness as a weaken co-limit, we describe dynamical negotiation between making parts and making whole in a lattice theory as a model for differentiation under a constraint of unity.

We prove new automorphy lifting theorems for essentially conjugate self-dual Galois representations into GLn. Existing theorems require that the residual representation have ‘big’ image, in a certain technical sense. Our theorems are based on a strengthening of the Taylor-Wiles method which allows one to weaken this hypothesis.

It is proved herein that any absolute minimizer u for a suitable Hamiltonian H ∈ C(R × R× U) is a viscosity solution of the Aronsson equation: Hp(Du, u, x) · (H(Du, u, x))x = 0 in U. The primary advance is to weaken the assumption that H ∈ C, used by previous authors, to the natural condition that H ∈ C.

We study the structure of shocks in clumpy media, using a multifluid formalism. As expected, shocks broaden as they weaken: for sufficiently weak shocks, no viscous sub-shock appears in the structure. This has significant implications for the survival of dense clouds in regions overrun by shocks in a wide range of astrophysical circumstances , from planetary nebulae to the nuclei of starburst g...

Osteoid osteomas may be treated medically or surgically; both have similar long-term outcomes. Nonetheless, only surgery allows complete excision of the lesion for histological analysis. Excessive removal of surrounding bone may destabilise and weaken the bony structure and predispose it to fractures. We describe a surgical technique using a bone graft trephine to enable precise lesion removal ...
