BERLIN, April 16 (Xinhua) -- World super middleweight champion Felix Sturm announced Saturday he failed a doping test following his win over Russia's Fedor Chudinov last February.

Sturm, 37, tested positive for anabolic steroid Hydro-XY Stanozolol in his A sample after he beat Chudinov on majority decision in Oberhausen on February 20 for the WBA super middleweight belt.

The five-time world champion German said he was shocked by his doping result and denied any wrongdoing.

Two units under internet giant Alibaba Group Holding Ltd are working in tandem to test facial recognition technology that will allow users to unlock delivery drop boxes.

Cainiao Network Technology Co Ltd nike air force 1 bianche saldi , an Alibaba-backed courier aggregator, is promoting such an application to its partner delivery firms and parcel pickup facility providers in a test run in Shanghai, the company said during a customer conference in Shanghai on Thursday.

The technology is provided by Ant Financial Services Group, Alibaba's fintech subsidiary, which since September has enabled customers to pay by literally flashing a smile in a KFC store in Hangzhou, where Alibaba is headquartered.

An army of specially equipped kiosks have been installed across five locations at Shanghai's financial district of Lujiazui nike cortez uomo saldi , with cameras scanning people's faces to verify their identities. The companies plan for a nationwide rollout when the pilot projects mature in the city.

In the first instance, the machine would compare the detected face with the image logged by public security authorities, said Chen Jidong, director of biometric identification technology at Ant Financial.

To achieve that, users need to subscribe to a service embedded in the Alipay digital wallet, which gives the app the green light to capture their personal information to confirm their identity nike cortez classic saldi , he noted.

This is possible thanks to 550 million real-name users on Alipay, through which they pay bills, settle traffic fines, manage wealth and get small loans.

"The scanning system focuses on your face, so it doesn't matter if you change your makeup or wear a wig," Chen said nike air presto uncaged saldi , adding that multiple tests have been conducted under various environments such as under sunlight or in the dark to ensure a smooth and consistent performance.

A demonstration video displayed during the conference suggested the whole process takes roughly five seconds, significantly shortening the conventional method of parcel retrieval by typing in text codes, which normally takes 16 seconds, the companies said.

"I would expect this investment and new process to save a substantial amount of time and ensure security," said Zou Jianhua, CEO of Diyi Box nike air presto woven saldi , a parcel pickup facility provider. "Just in Shanghai, at least 10,000 parcel pickup locations will be equipped with such functionality in three years."

Chen said that the false-acceptance rate, or the chances that the system incorrectly accepts an unauthorized user, should be below 0.001 percent and be further lowered to ensure bank-level security.

Shenzhen-based SF Express, a leading Chinese courier that is competing with Cainiao's network nike air presto ultra flyknit saldi , said it is also developing biometric-based technologies to apply to its own parcel pickup cabinets.

HOUSTON, Sept. 20 (Xinhua) -- In the aftermath of tropical storm Harvey, expert believe there is a long way to go to improve emergency preparedness system in the United States.

Category four Hurricane Harvey made a landfall along the coast of Gulf of Mexico. The storm brought unprecedented rainfall to the greater Houston area in south U.S., killing dozens of people. Texas Governor Greg Abbott said damage by Hurricane Harvey would reach 150 billion to 180 billion U.S. dollars.

During an exclusive interview by Xinhua, Jim Blackburn, co-director of Severe Storm Prediction nike air presto qs saldi , Education and Evacuation Center from Disasters in Rice University, said the disaster showed there is a lot to improve the emergency preparedness system in the U.S.

"We have a long way to go in emergency preparedness system. There's a much better warning system that we could have. In fact it would be very easy to have."

According to him, the flood-alert system in the Texas Medical Center (TMC) in Houston sets a good example for the entire country.

Designed by Rice University civil engineering professor Philip Bedient and other experts, the Flood Alert System - now in its third version - uses radar, rain gauges, cameras and modeling to indicate whether Houston's Brays Bayou is at risk of overflowing and flooding the TMC. The system can predict maximum flooding conditions two to three hours ahead of time and track rain totals more accurately than radar alone.

The lead time was crucial nike air presto nere saldi , said TMC's President and CEO Bill McKeon. It allowed the hospitals to shut their floodgates and evacuate basement garages before the flood hit.

In the end, the only damage the hospital sustained was downed trees and leaky roofs, McKeon said.

This was not the first time the system worked well. When Tropical Storm Allison hit Houston in 2001, the system gave accurate predictions. During the past two decades, it has been upgraded from the first version to the third and monitored more than 150 storms.

In an interview with local newspaper in 2015, Bedient said the existing National Weather Service only issues warning by county which is too general nike air presto bianche saldi , while the TMC Flood Warning System is designed to provide its users more specific flood warnings by monitoring key watersheds. Moreover, the system is interactive and provides real time updates every five minutes.

Blackburn believed the flood alert system in TMC should be widely used in the country. "It tells them when they need to deploy their flood gates that they have, it tells them when to tell their employees not t.
