PURPOSE The aim of this study was to evaluate via Fourier-domain anterior-segment optical coherence tomography 3-dimensional corneal, epithelial, and graft thickness changes after Descemet stripping automated endothelial keratoplasty (DSAEK). METHODS Sixteen eyes were investigated preoperatively and up to 6 months postoperatively for preoperative and postoperative central corneal thickness (C...

The MALTA pixel chip is a 2 cm × large monolithic detector developed in the Tower 180 nm imaging process. contains four CMOS transceiver blocks at its sides which allow chip-to-chip data transfer. power pads are located mainly side edges on allows for transmission. has been used to study module assembly using different interconnection techniques transmit and from minimise overall material budge...

Whereas the previous chapters focused mainly on the physical basics of surface plasmon resonance, instrumentation and assay design, we will now turn to the heart of SPR and related biosensors: the sensor chip and its surface chemistry. It is here where the biomolecular interaction takes place and although dimensionally extremely small (the coating thickness is measured in nanometers), the senso...

The current work presents a quantitative approach for the prediction of minimum film thickness in elastohydrodynamic-lubricated (EHL) circular contacts. In contrast to central thickness, can be hard accurately measure, and it is usually poorly estimated by classical formulae. For this, an advanced finite element-based numerical model used quantify variations central-to-minimum ratio with operat...

Endometrial thickness is defined as the minimal distance between the echogenic interfaces of myometrium and endometrium. An adequate thickness of endometrium is indispensable for embryo implantation [1-4]. The minimum endometrial thickness that may cause a successful implantation is called “threshold thickness”. The endometrium that is thinner than “threshold thickness” is called “thin endometr...

This paper presents a new, high-performance silicon-on-insulator (SOI) MEMS gyroscope with decoupled oscillation modes. The gyroscope tructure allows it to achieve matched-resonance-frequencies, large drive-mode oscillation amplitude, high sense-mode quality factor, and low echanical cross-talk. The gyroscope is fabricated through the commercially available SOIMUMPS process of MEMSCAP Inc. The ...

This paper discusses the resistive termination of on-chip high-performance interconnects. Resistive termination is effective to improve the bandwidth of on-chip interconnects, on the other hands, increases the power dissipation and the area. Therefore trade-off analysis about resistive termination is necessary. This paper proposes a method to determine the termination of on-chip interconnects. ...

background: although studies have shown that porcelain veneers are very effi cient for treating discolored teeth, they did not address in particular the minimum thickness of a multilayer ips e.max press (ivoclarvivadent, schaan, liechtenstein) restoration required to mask discolored tooth. the aim of this study was to determine the minimum thickness of a multilayer porcelain restoration require...
