Silicon-on-insulator wavelength-selective filter with integrated detectors at the 2 µm wave band.

The short-wave infrared range is highly significant for spectroscopic sensing and upcoming optical communication applications. Integrating active and passive photonic components is essential to achieve compact optical solutions. In this paper, we show, for the first time to our knowledge, a wavelength-selective detection system based on the heterogeneous integration of two grating-coupled InGaAs photodetectors operating at the 2µm wave band, with a wavelength selectivity provided by a dual-channel Mach-Zehnder interferometer fabricated using a silicon-on-insulator (SOI) wafer.

Integration of High-Performance InGaAs/GaN Photodetectors by Direct Bonding via Micro-transfer Printing.

The integration of dissimilar semiconductor materials holds immense potential for harnessing their complementary properties in novel applications. However, achieving such combinations through conventional heteroepitaxy or wafer bonding techniques presents significant challenges. In this research, we present a novel approach involving the direct bonding of InGaAs-based p-i-n membranes with GaN, facilitated by van der Waals forces and microtransfer printing technology.

Effect of the Gupta Score on Pre-operative Cardiology Consultation Requests in Noncardiac Nonvascular Surgery.

Objective: Cardiologists are the most frequently consulted specialists during pre-operative evaluations. However, unnecessary cardiology consultations (CC) can increase cardiologists' workload without impacting anaesthesia practice, resulting in delayed surgeries and additional financial burdens. We hypothesize that using Gupta during the preoperative period can reduce these adverse effects.

Comparison of Two Different Methods for ProSeal Laryngeal Mask Fixation.

Dietary advices for patients with metabolic syndrome and obesity.

Obesity and metabolic syndrome are two important health problems that have increased in incidence in recent years in all around world. Stone occurrence and recurrence risks are increased in these diseases. Apart from general dietary recommendations for stone patients, metabolic evaluation and personalized dietary recommendations are important in these patients.

Attitudes of urologists on metabolic evaluation for urolithiasis: outcomes of a global survey from 57 countries.

Although stone disease is an important health problem with high incidence and recurrence rates, it is a preventable disease. Attitudes and practices of urologists regarding the prevention of recurrence continue to be a subject of debate. In this context, an online survey study was conducted involving 305 urologists from 57 different countries.

Optimal patient position for percutaneous nephrolithotomy in horseshoe kidneys: Traditional prone or supine?

Objective: Although it was stated that supine percutaneous nephrolithotomy (PCNL) was associated with relatively shorter surgical times and comparable success and complication rates, there is no consensus in the current literature concerning the safety and efficacy of supine PCNL in patients with horseshoe kidneys. We aimed to compare supine and prone PCNL regarding safety and efficacy in patients with horseshoe kidneys.

Methods: Data of the patients with horseshoe kidneys who underwent PCNL for renal stones larger than 2 cm between January 2010 and May 2021 were retrospectively reviewed.

Objective: To identify the preoperative and intraoperative factors that might cause systemic inflammatory response syndrome (SIRS) after retrograde intrarenal surgery (RIRS), and to investigate the effect of time elapsed between the date of performing preoperative bladder urine culture (PBUC) and surgery date on postoperative SIRS.

Materials And Methods: Four hundred sixty-seven patients who had RIRS between January 2013 and June 2020 constituted the target population of this study. PBUC were obtained from all patients before undergoing surgery.

Supine Percutaneous Nephrolithotomy in a Patient with Solitary Lung: A Case Report and Literature Review.

Percutaneous nephrolithotomy (PNL) surgeries are performed with different patient positions, anesthesia methods and different-sized access sheaths in order to reduce the complication rates. Supine positioned PNL can be performed safely in the high-risk group patients with comorbidities. Herein, we present a patient who had a past surgical history of right pneumonectomy and underwent a supine PNL procedure under regional anesthesia for a staghorn renal stone in the right kidney.

Can shock wave lithotripsy lead to impaction of ureteral stones?

Background: One of the underlying reasons for shock wave lithotripsy (SWL) resistance is the ureteral stone impaction. This study aimed to investigate the accuracy of the hypothesis, suggesting that SWL per se can be the reason for ureteral stone impaction.

Methods: One hundred and seventy-six patients were enrolled in the study.

CMOS-Compatible Titanium Nitride for On-Chip Plasmonic Schottky Photodetectors.

Here, we propose a waveguide-integrated plasmonic Schottky photodetector (PD) operating based on an internal photoemission process with a titanium nitride plasmonic material. The theoretically examined structure employs an asymmetric metal-semiconductor-metal waveguide configuration with one of the electrodes being gold and the second being either gold, titanium, or titanium nitride. For the first time, we measured a Schottky barrier height of 0.

Plasmonic Schottky photodetector with metal stripe embedded into semiconductor and with a CMOS-compatible titanium nitride.

Here we propose an original waveguide-integrated plasmonic Schottky photodetector that takes full advantage of a thin metal stripe embedded entirely into a semiconductor. The photodetector is based on the long-range dielectric-loaded surface plasmon polariton waveguide with a metal stripe deposited on top of a semiconductor rib and covered by another semiconductor. As the metal stripe is entirely surrounded by semiconductor, all hot electrons with appropriate k-vectors can participate in transitions that highly enhances the electron transfer, and consequently the internal quantum efficiency.

Gasless robotic perineal radical prostatectomy: An initial experience.

Radical prostatectomy (RP) is the gold standard treatment method of localized prostate cancer. Today, this surgery is performed with open or minimally invasive methods. The history of open perineal RP (RPP) is very old, but it is not often preferred by urologists.
