Time-bin entangled Bell state generation and tomography on thin-film lithium niobate.

Optical quantum communication technologies are making the prospect of unconditionally secure and efficient information transfer a reality. The possibility of generating and reliably detecting quantum states of light, with the further need of increasing the private data-rate is where most research efforts are focusing. The physical concept of entanglement is a solution guaranteeing the highest degree of security in device-independent schemes, yet its implementation and preservation over long communication links is hard to achieve.

Clinical outcomes after emergency transarterial renal embolization: a retrospective study.

Background: Studies on emergency transarterial embolization (TAE) of renal arterial injuries are rare. The aim of this retrospective study was to evaluate clinical outcomes after emergency transarterial renal embolization.

Material And Methods: Between January 1st, 2013 and January 1st, 2024, all consecutive patients treated for renal arterial injuries by TAE in emergency settings were retrospectively reviewed.

From high- to low-contrast: the role of asymmetries in dielectric gratings supporting bound states in the continuum.

One-dimensional sub-wavelength gratings are versatile photonic platforms supporting diverse resonances, including symmetry-protected bound states in the continuum. However, practical access to these bound modes relies on their quasi-bound form, which necessitates the introduction of perturbations in either geometry or material properties. Despite having a large, finite quality factor, quasi-bound modes retain their characteristically strong field confinement.

Cryoablation for treatment of peripheral lung metastases from colorectal cancer: a bicenter retrospective study.

Objectives: To evaluate the oncological efficacy and complications of cryoablation (CA) in treating lung metastases from colorectal cancer (CRC) at the lung periphery.

Materials And Methods: The inclusion criteria for this bicenter retrospective study included patients with histologically confirmed CRC, with radiologically confirmed lung metastases at the periphery of the lung (distance of less than or equal to 2 cm from the costal, diaphragmatic, or cervical pleura) treated with CA between January 2017 and June 2022. Patients with intra-parenchymal metastases or metastases close to the mediastinal pleura and patients without follow-up were excluded.

Pancreatic steatosis is a strong risk factor for post-ERCP pancreatitis: An emerging concept.

Objective: The Endoscopic Retrograde Cholangiopancreatography (ERCP) is the treatment of choice for biliary obstruction but is associated with post-ERCP pancreatitis (PEP) in around 5 % of cases. No radiological criteria have been evaluated for predicting PEP risk.

Design: This retrospective study examined records of 1365 patients who underwent ERCP at our center between 2014-2023.
