Rotation, Shifting, and Translation (RST) invariant image watermarking is a very important research topic. In this letter, we report a new filtering method in the log-polar mapping (LPM), and a novel rectification method that can be used in any RST invariant image watermarking algorithms. We get a log-polar mapping of an image by calculating the Fourier transform of the image and resampling the...

Purpose: The aim of present study was to improve the dissolution rate of poorly soluble drug Loperamide (LPM) by liquisolid compact technique. Methods: Liquisolid compacts of LPM were prepared using Propylene glycol (PG) as a solvent, Avicel pH 102 as carrier, Aerosil as coating material and Sodium Starch Glycolate (SSG) as superdisintegrant. Interactions between the drug and excipients were ex...

OBJECTIVES The aim of this experiment was to detect pressure pain threshold (PPT) differences on intra-oral palpation of the lateral pterygoid muscle (LPM) between subjects diagnosed with temporomandibular disorders (TMD) and controls. METHODS Thirty-one consecutive female TMD patients and 31 age and gender matched controls underwent palpation of the LPM using an algometer made with a queue-t...

We have studied the effect of the boundaries on the local density of states (LDOS) in one-, two-, and three-dimensional finite size photonic structures. The LDOS was calculated with the help of the local perturbation method (LPM) and a new LPM-Bloch method using periodicity of the system. The methods are applicable for the clusters made of small (relative to the incident wavelength) particles o...

This paper proposes an RST−invariant multi−bit watermarking system based on LPM and DFT. This system embeds the watermark in a rotation and translation invariant domain obtained by first acquiring log−polar mapped DFT (LPM−DFT) magnitudes of an image, and then taking the magnitude of the 1−dimensional DFT along the angular axis of this LPM−DFT magnitudes. Neither the original cover image nor a ...

It is well known that beamstrahlung and bremsstrahlung take place over a finite formation zone distance. If something disturbs the electron during this time, the emission can be suppressed. In this paper, we examine the Landau-PomeranchukMigdal (LPM) effect and other LPM-like effects, such as the longitudinal density (dielectric) suppression and EM field suppression of beamstrahlungand bremsstr...

Handoff is one of the most important factors that may degrade the performance of TCP connections in wireless data networks. In this paper, we present a lossless and duplication free handoff scheme called LPM (Last Packet Marking) for improving Cellular IP semisoft handoff. LPM signals the safe handoff cue by sending a specially marked packet to mobile hosts. With this control packet, MH can ada...

The suitability of seven media for the enumeration of Listeria spp. was evaluated at 30 degrees C for 48 h. The media tested were (i) the original McBride Listeria agar formulation (with glycine); (ii) modified McBride agar containing glycine anhydride; (iii) LiCl-phenylethanol-moxalactam (LPM) agar; (iv) acriflavine-ceftazidime agar; (v) Rodriguez isolation agar (RISA); (vi) modified Vogel-Joh...

We studied the effect of cyclosporin A (CyA) on liver plasma membrane (LPM) composition, fluidity, and functions and on hepatic glutathione (GS) and oxidative status. We also evaluated the ability of S-adenosylmethionine (SAMe) to antagonize the CyA-induced disturbances in rats. The animals were randomly divided into four groups and treated daily with saline, CyA vehicle, CyA, and SAMe plus CyA...

Worldwide spreading of drug-resistant pathogens makes mechanistic understanding of antibiotic action an urgent task. The macrocyclic antibiotic lipiarmycin (Lpm), which is under development for clinical use, inhibits bacterial RNA polymerase (RNAP) by an unknown mechanism. Using genetic and biochemical approaches, we show that Lpm targets the sigma(70) subunit region 3.2 and the RNAP beta' subu...
