Directed compact percolation: cluster size and hyperscaling [PDF]
Exact recurrence relations are obtained for the length and size distributions of compact directed percolation clusters on the square lattice. The corresponding relation for the moment generating function of the length distribution is obtained in closed form whereas in the case of the size distribution only the first three moments are obtained. The work

A Nearby Analog of z~2 Compact Quiescent Galaxies with a Rotating Disk
Recent studies have identified a population of compact quiescent galaxies at z\sim2. These galaxies are very rare today and establishing the existence of a nearby analog could allow us to study its structure in greater detail than is possible at high ...

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Simulating the X-ray luminosity of Be X-ray binaries: the case for black holes versus neutron stars
There are over 100 Be stars that are known to have neutron star companions but only one such system with a black hole. Previous theoretical work suggests this is not due to their formation but due to differences in X-ray luminosity.

High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

A Compact Formulation for the $\ell_{2,1}$ Mixed-Norm Minimization Problem
Parameter estimation from multiple measurement vectors (MMVs) is a fundamental problem in many signal processing applications, e.g., spectral analysis and direction-of- arrival estimation.

The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

A Compact Dual-Band Quasi-Elliptic Filter Employing Meander-Line- and CRLH-Based SIW Triplets
A compact dual-band quasi-elliptic filter with high selectivity is developed and investigated in this communication. It employs two hybrid-structure substrate integrated waveguide (SIW) triplets, which show completely inverse transfer responses under the

Experimental study on effect of scaling on compact density of coarse-grained soils
There is a certain difference in compact density of rockfill materials between the real gradation and corresponding scaling gradation. In order to describe the difference quantitatively, the scaling effect can be divided into two parts, changes of the ...
