Etching of GaAs, when plasma of Ar gas is used and CF4 /O2 is directed fall on the wafer from another port in Electron Cyclotron Resonance (ECR) source in Chemically Assisted Ion Beam Etching (CAIBE) has been carried out. The plasma source was 2.45 GHz microwave source superimposed with mirror type magnetic field configuration to have resonance. Effect of CF4/O2/Ar ratio and substrate bias on e...

This paper decribes a novel method for detecting nonstationary signals in colored noise. A first order complex autoregressive, or AR(l), signal model is used which restricts the application of the detector to low order signals, i.e., those which are well modeled by a low order AR process and have only a single spectral peak. The detector assumes the noise covariance is stationary and known. The...

PURPOSE The expression and involvement of estrogen (ER) and progesterone receptor (PR) is extensively studied in endometrial cancer. Androgen receptor (AR) is a hormone receptor less studied in female cancers, and we here aim to investigate the expression level of AR in endometrial cancer precursor lesions, primary tumors and metastases, and its potential as therapeutic target. RESULTS Expres...

The present study demonstrates a single-molecular bioluminescent probe carrying functional peptides in the N-terminal domain of the androgen receptor (AR NTD) with an improved sensorial property to androgens. The N-terminal peptides in AR were genetically fused to the ligand binding domain of AR (AR LBD) with a flexible linker, and then sandwiched between the N- and C-terminal fragments of spli...

Stroke is one of the leading causes of disability in all over the world. This disability greatly impacts the stroke patients’ daily life activities. Thus, rehabilitation exercises are essential for post stroke patients to restore their lost functions gradually for daily life activities. Traditional rehabilitation exercises do not motivate the post stroke patients as they are normally humdrum an...

We report the 790 nm photofragmentation of mass-selected I2 2 •Arn clusters, n51 to 27. We determine the I1I caging efficiency as a function of the number of solvent Ar atoms and compare these results with I2 2 in CO2 clusters. Caging is much less effective with Ar. In addition to ‘‘normal’’ caged photoproducts ~I2 2 •Arm , where m,n!, the evaporation process following photoexcitation produces ...

Reproducibly achieving proper implant alignment is a critical step in total hip arthroplasty procedures that has been shown to substantially affect patient outcome. In current practice, correct alignment of the acetabular cup is verified in C-arm x-ray images that are acquired in an anterior-posterior (AP) view. Favorable surgical outcome is, therefore, heavily dependent on the surgeon's experi...

Operating a robot from a distant place using haptic and visual feedback gets enormous applications in various situations. But due to time-delay in the communication, an tele-operator sometimes has to go for a move-n-wait strategy. However, the problem can be minimized by using Augmented Reality (AR) concepts of superimposing virtual objects onto the real video image of the remote scene to creat...

Our recent retrospective study revealed a significantly reduced risk of bladder cancer (BC) recurrence in men who received androgen deprivation therapy (ADT) for their prostate cancer. However, whether androgen receptor (AR) signals contributed to the preventive effect of ADT remained unclear because ADT could reduce serum estrogens as well. The purpose of this study is to investigate the assoc...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...
