A Higman-Haemers Inequality for Thick Regular Near Polygons [PDF]

open access: yesJournal of Algebraic Combinatorics, 2004
Let \(\Gamma\) be a generalized \(n\)-gon of order \((s, t)\) (i.e. on every line there are exactly \(s+1\) points and every point lies on \(t+1\) lines). W. Feit and D. G. Higman showed that, apart from the ordinary polygons, finite examples only exist for \(n = 3, 4, 6, 8\) or \(12\). If \(s>1\) and \(t>1\), then \(n = 12\) is not possible.

Thermal Radiation Emission From 3D Graphene Networks

open access: yesAdvanced Materials Interfaces, EarlyView.
Three‐dimensional graphene networks are demonstrated as exceptional broadband thermal emitters, exhibiting high‐intensity, spectrally homogeneous emission and strong mechanical flexibility compared to conventional emitters like silicon carbide.

The valuations of the near polygon G\(_{n}\)

open access: yesElectron. J. Comb., 2009
The author classifies the valuations of the near polygon \(\mathbb{G}_n\). A \textit{near polygon} is a point-line incidence geometry such that two points determine at most one line, and for each point \(p\) and line \(L\), there is a unique point on \(L\) nearest to \(p\) in the point collinearity graph.

The Universal Embedding of the Near Polygon ${\Bbb G}_n$ [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2007
In an earlier paper, we showed that the dual polar space $DH(2n-1,4)$, $n \geq 2$, has a sub near-$2n$-gon ${\Bbb G}_n$ with a large automorphism group. In this paper, we determine the absolutely universal embedding of this near polygon. We show that the generating and embedding ranks of ${\Bbb G}_n$ are equal to ${2n \choose n}$. We also show that the

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

open access: yesAdvanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

CREATING THE KULTUK POLYGON FOR EARTHQUAKE PREDICTION: VARIATIONS OF (234U/238U) AND 87SR/86SR IN GROUNDWATER FROM ACTIVE FAULTS AT THE WESTERN SHORE OF LAKE BAIKAL

open access: yesГеодинамика и тектонофизика, 2015
Introduction. Determinations of (234U/238U) in groundwater samples are used for monitoring current deformations in active faults (parentheses denote activity ratio units). The cyclic equilibrium of activity ratio 234U/238U≈≈(234U/238U)≈γ≈1 corresponds to

An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

open access: yesAdvanced Materials Technologies, EarlyView.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...

Investigation into valuation of land using remote sensing and GIS in Madurai, Tamilnadu, India

open access: yesEuropean Journal of Remote Sensing, 2020
Assessing the value of property is important in the real estate activity. Important factor to assess the property value is the location of the property. In India, value of a property is mainly evaluated by the guideline value and the market value.
