Computation of a large group of interior eigenvalues at the middle spectrum is an important problem for quantum many-body systems, where the level statistics provides characteristic signatures of quantum chaos.We propose an exact numerical method, dual applications of Chebyshev polynomials (DACP), to simultaneously find thousands of central eigenva
Abstract Effective absorption of low-frequency waterborne sound with subwavelength absorbers has always been a challenging work.In this paper, we derive two theoretical requirements for broadband perfect absorption of low-frequency waterborne sound by ultrathin acoustic metasurface under a finite-thickness steel plate followed by semi-infinite air.
The recent identification of copy-number variation in the human genome has opened up new avenues for the discovery of positional candidate genes underlying King Poster Bed with storage complex genetic disorders, especially in the field of psychiatric disease.One major challenge that remains is pinpointing the susceptibility genes in the multitude o
Migration of bullet in the canal is rare and intradural migration is even rarer.Most migration are caudal to the site of trauma.This case presents present a case of 27 years old man who sustained a bullet injury on his back at L1 Golf Ball with no exit site.He was having generalized tenderness on his abdomen and complete neurologic injury below the
In recent years, hybrid structures have attracted wide consideration because they generate new very interesting properties.In this study, a hybrid gas sensor was developed using a simple fabrication process from the combination of porous silicon (PSi) and polythiophene (PTh).The study of the effect of electropolymerization rate and Vitamin and Mine
