Experimental demonstration of a reconfigurable free-space receiver implementing polarization routing and filtering for daytime quantum key distribution.

Free-space quantum key distribution (QKD) systems are often designed to implement polarization-encoding protocols. Alternatively, time-bin/phase-encoding protocols are considerably more challenging to perform over a channel experiencing atmospheric turbulence. However, over the last decade, new and improved optical platforms have revived the interest in them.

Quantum bit error rate timing jitter dependency on multi-mode fibers.

The full time-jitter response of a single-photon detector can make a significant contribution to the quantum bit error rate (QBER) of high repetition rate quantum key distribution (QKD) implementations. Although there have been studies into understanding the contribution for single-mode optical fiber coupled single-photon detectors, the contribution of larger, multimode core diameters to the QBER have not been explored in detail. With the growing importance of free-space QKD, which typically use multimode fibers to reduce coupling loss, it is vitally important to understand how the multimode fiber coupling will impact the total QBER.

Cerebral Venous Sinus Thrombosis Treated with Vacuum Aspiration Thrombectomy without Thrombolysis: A Descriptive and Retrospective Study of 5 Years' Experience at a Single Center.

Purpose: Cerebral venous sinus thrombosis (CVST) is a rare but life-threatening condition. Mechanical thrombectomy is a treatment option for patients who deteriorate or do not improve despite anticoagulation treatment or those who have a major contraindication to anticoagulation. The purpose of this study was to describe the authors' 5 years of experience in treating CVST with vacuum aspiration thrombectomy without thrombolysis.

Toxicological evaluation of an aqueous suspension from leaves and stems of Petiveria alliacea L. (Phytolaccaceae).

Ethnopharmacological Relevance: Petiveria alliacea L. (Phytolaccaceae) is used in folk medicine due to its antispasmodic, diuretic, hypoglycemic, abortive, anti-inflammatory and anticancerogenic properties. Although P.

Antioxidant and toxicological evaluation of a Tamarindus indica L. leaf fluid extract.

In the scientific community, there is a growing interest in Tamarindus indica L. leaves, both as a valuable nutrient and as a functional food. This paper focuses on exploring its safety and antioxidant properties.

Embryonic and larval development of Eugerres mexicanus (Perciformes: Gerreidae) in Tenosique, Tabasco, Mexico.

Most studies on Eugerres mexicanus mainly consider biogeographic and systematic aspects and rarely address reproductive characteristics, which are useful for fishery population management plans. This study aimed at evaluating the ontogeny of E. mexicanus, based on 30 embryos and 30 larvae sampled by induced spawning of breeders, taken in February 2009 from the Usumacinta River in Tenosique, Tabasco, Mexico.
