Identification of inhibitors of the Salmonella FraB deglycase, a drug target
FEBS Open Bio, EarlyView.A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

Complete N-Point Superstring Disk Amplitude II. Amplitude and Hypergeometric Function Structure [PDF]
, 2011 Using the pure spinor formalism in part I [1] we compute the complete tree-level amplitude of N massless open strings and find a striking simple and compact form in terms of minimal building blocks: the full N-point amplitude is expressed by a sum over ...

Amplitude control of quantum interference
, 2012 Usually, the oscillations of interference effects are controlled by relative phases. We show that varying the amplitudes of quantum waves, for instance by changing the reflectivity of beam splitters, can also lead to quantum oscillations and even to Bell

Expansion of tree amplitudes for EM and other theories [PDF]
Prog Theor Exp Phys (2020), 2019 The expansions of tree-level amplitudes for one theory into amplitudes for another theory, which have been studied in various recent literatures, exhibit hidden connections between different theories that are invisible in traditional Lagrangian formulism of quantum field theory.

Development of difference spectrophotometric method for the estimation of leflunomide in tablet dosage form [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2012 A new simple, accurate, precise, highly sensitive and reproducible difference spectrophotometric method for the determination of leflunomide in bulk and pharmaceutical dosage form is described. Difference spectroscopic method is based on the principle

A relation between massive and massless string tree amplitudes [PDF]
arXiv, 2023 We uncover a relation between the scattering amplitudes of massive strings and the $\alpha'$ expansion of the massless string amplitude at tree level. More precisely, the n-point tree amplitude of n-1 massless and one massive state is written as a linear combination of n+1 massless string amplitudes at the $\alpha'^2$ order.

Physical Simulation of Ultrasonic Imaging Logging Response
Sensors, 2022 Ultrasonic imaging logging can visually identify the location, shape, dip angle and orientation of fractures and holes. The method has not been effectively applied in the field; one of the prime reasons is that the results of physical simulation ...
