Self stabilizing sonic inlet [PDF]
, 1979 An inlet suitable for a turbine engine in a STOL, VTOL or CTOL aircraft is described. A circumferentially extended slot is provided in the inner surface of the air inlet at the windward side and downstream of the throat region. The slot communicates with

Advanced Science, EarlyView.A multifaceted chemical strategy, integrating bacterial tropism, metal‐ion interference therapy, and immunotherapy, resulted in significant tumor regression in murine models. A pioneering paradigm for the design of biohybrid materials was established, highlighting how sophisticated chemical engineering of living systems can unlock new avenues for ...

Advanced Science, EarlyView.Imidazolium PIL nanoparticles, as an N‐rich template and morphology director, enable a colloidal self‐nitriding route to TMNs (VN, Mo2N) within controlled solid/hollow carbon architectures. As sulfur hosts/additives, TMNs accelerate Li–S redox kinetics and support high‐loading cathodes.

Theoretical evaluation of engine auxiliary inlet design for supersonic V/STOL aircraft [PDF]
A higher order panel method is used to evaluate the potential flow of a 2-D supersonic V/STOL inlet. A nonsymmetric analytical inlet model is developed to closely match a wind tunnel model tested at NASA-Lewis.

The approximation property for spaces of Lipschitz functions [PDF]
, 2014 Let $\mathrm{Lip}_0(X)$ be the space of all Lipschitz scalar-valued functions on a pointed metric space $X$. We characterize the approximation property for $\mathrm{Lip}_0(X)$ with the bounded weak* topology using as tools the tensor product, the ...

Scalable Manufacturing of Roll‐to‐Roll Slot‐Die Coated Perovskite Solar Cells
Advanced Science, EarlyView.Roll‐to‐roll (R2R) slot‐die coating is emerging as a scalable pathway for perovskite solar cells. This mini‐review summarizes advances in ink design, drying control, and electrode integration that enable high‐efficiency flexible devices and modules. Challenges in throughput, stability, and sustainable processing are outlined, guiding the translation of

Syringocystadenoma Papilliferum of the Upper Lip
Sultan Qaboos University Medical Journal, 2014 Syringocystadenoma papilliferum (SCAP) is a rare skin tumour believed to arise from the apocrine or eccrine sweat glands. It appears predominantly in childhood, usually at birth. It is exceedingly rare for it to appear on the upper lip.

On the Lattice Isomorphism Problem
, 2013 We study the Lattice Isomorphism Problem (LIP), in which given two lattices L_1 and L_2 the goal is to decide whether there exists an orthogonal linear transformation mapping L_1 to L_2. Our main result is an algorithm for this problem running in time n^{
