String Junctions and the BPS Spectrum of N=2 SU(2) Theory with Massive Matters [PDF]
, 1998 We study the BPS spectrum of four dimensional N=2 SU(2) theory with massive fundamental matters using the D3-brane probe. Since the BPS states are realized by string webs subject to the BPS conditions, we determine explicitly the configurations of such ...

Elementary stability considerations for bowed-string motion [PDF]
The Journal of the Acoustical Society of America, 1991 Using the approach first pioneered by Raman, the Helmholtz motion of a bowed string is discussed as a special case of “two-velocity motions,” in which a given point (at which the bow is located) alternates, in the course of a cycle, between two constant velocities. The fact that the bow typically presents a negative resistance to the string during the “

Advanced Functional Materials, EarlyView.A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Influence of drill-string lateral collision on wellbore stability of a horizontal well
Advances in Mechanical Engineering, 2022 A finite element model of wellbore stability was proposed for a horizontal well, and drill-string friction and lateral collision in the process of rotary motion were taken into account.

Stability Analysis of a Predecessor-Following Platoon of Vehicles With Two Time Delays
Promet (Zagreb), 2015 The problem of controlling a platoon of vehicles moving in one dimension is considered so that they all follow a lead vehicle with constant spacing between successive vehicles.

Spinning Strings, Black Holes and Stable Closed Timelike Geodesics
, 2008 The existence and stability under linear perturbation of closed timelike curves in the spacetime associated to Schwarzschild black hole pierced by a spinning string are studied. Due to the superposition of the black hole, we find that the spinning string

String Junctions and BPS States in Seiberg-Witten Theory [PDF]
, 1998 We argue that certain BPS states in the D3-brane probe realization of N=2 SU(2) Super-Yang-Mills theory correspond to multi-pronged strings connecting the D3-brane to the background 7-branes.

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
Advanced Functional Materials, EarlyView.A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.
