(Carnegie Mellon University) Intelligent tutoring systems have been shown to be effective in helping to teach certain subjects, such as algebra or grammar, but creating these computerized systems is difficult and laborious. Now, researchers at Carnegie Mellon University have shown they can rapidly build them by, in effect, teaching the computer to teach.

(University of Massachusetts Lowell) UMass Medical School and UMass Lowell will perform a key role in a new National Institutes of Health initiative aimed at speeding innovation, development and commercialization of COVID-19 testing technologies via their Center for Advancing Point of Care Technologies collaboration.

(Michigan Medicine - University of Michigan) They know it's addictive. They know it's linked to dangerous lung diseases. And they know it delivers more nicotine than the cigarettes it's supposed to replace. But the social aspects of vaping drives young people to use Juul and other e-cigarettes, according to nearly two-thirds of teens and young adults in a new study. Less than 5% say the availability of fruity flavors drives use of e-cigarettes by members of their generation, and only 10% say addiction does.

(University of Cambridge) Parents should not feel pressured to make their young children undertake structured learning or achieve specific tasks, particularly during lockdown. A new study of children under the age of two has found that parents who take a more flexible approach to their child's learning can - for children who were easy babies - minimise behavioural problems during toddlerhood.

The Government today announced that applications are open for several support schemes following the funding approval of the second round of the Anti-epidemic Fund and other relief measures by the Legislative Council Finance Committee.

The Club-house Subsidy Scheme, which provides a one-off subsidy of $100,000 to eligible club-houses, is now open for application. The deadline for application is May 18.

Upon submission of the completed application form and supporting documents, the disbursement of subsidies could generally be made in around two weeks.

The Travel Agents & Practitioners Support Scheme and the Hotel Sector Support Scheme are also open for applications, with the deadlines on June 15 and May 18 respectively.

The Subsidy Scheme for the Refuse Transfer Station Account Holders for Transporting Municipal Solid Waste, which offers a one-off subsidy of $8,000 to each of the eligible private municipal solid waste collectors operating in the first quarter, was also endorsed.

To ease the application procedures, the Environmental Protection Department will post cheques to recipients of this special subsidy in about a week after the funding endorsement.

Meanwhile, the total guarantee commitment of the Special 100% Loan Guarantee under the SME Financing Guarantee Scheme has been increased to $50 billion.

The maximum loan amount per enterprise has been increased to $4 million and the principal moratorium arrangement has been extended to the first 12 months.

The Special 100% Loan Guarantee will start receiving applications from April 20 and the application period has been extended to one year.

With the northeast monsoon over southern China being stronger than normal in April, the month was slightly cooler than usual, the Hong Kong Observatory said today.

The monthly mean temperature was 22 degrees Celsius, 0.6 degrees below normal.

The mean minimum temperature was 20 degrees Celsius, 0.8 degrees below average, while the monthly mean maximum temperature was 25.1 degrees Celsius, 0.1 degrees above normal.

The month was also drier than usual with a total rainfall of 77.8mm, about 55% below the normal figure.

The accumulated rainfall recorded in the first four months of the year was 213.7mm, about 36% below average.

In March, Hong Kong International Airport (HKIA) became the first in the world to be certified as an International Air Transport Association (IATA) Center of Excellence for Perishable Logistics (CEIV Fresh) Partner Airport.

Two of the airport’s cargo terminal operators, Hong Kong Air Cargo Terminals Limited (HACTL) and Cathay Pacific Services Limited (CPSL) have achieved IATA CEIV Fresh Certification, while Cathay Pacific recently became the world’s first airline to be certified.

IATA created the Centre of Excellence for Independent Validators (CEIV) to help organisations involved in the air cargo supply chain achieve handling excellence.

The certification underscores the speed, consistency and efficiency of all HKIA stakeholders when it comes to the treatment and transportation of perishable products.

It also helps to ensure food safety, and reduce food wastage and loss along the supply chain.

Quality benchmark

Hong Kong Air Cargo Terminals Limited Chief Executive Wilson Kwong said the main value of the accreditation is that it provides a universally recognised standard.

“It gives assurance to the various stakeholders that we have, and we are adhering to the highest possible standards.”

Both accredited cargo terminal operators HACTL and CPSL have set up perishable cargo handling areas with truck docks next to the apron.

As soon as the perishable goods are unloaded from the aircraft, they are immediately transported to the handling area.

The clearance and sampling checks have been streamlined to minimise the time taken to unload the goods. There are cold rooms set at tailored temperatures for various kinds of perishable cargo.

Their staff training and handling process have also been assessed and certified for their compliance with the global industry standards.

Cathay Pacific Services Limited Chief Executive Officer Jenny Lam noted that one of the challenges in meeting the certification standard is training its 2,000 employees in handling and storing perishable goods.

“They first have to identify what types of perishables they are, such as are they flowers, are they fruits, are they meat, so that they know how to segregate the storage.

“Secondly, they gain knowledge about certain fruits that cannot be put close to each other such as bananas and apples.”

Growth opportunities

In 2018, the airport handled about 380,000 tonnes of perishable cargo - a rise of 12% on 2017, with perishables accounting for about 8% of total air cargo volume.

Airport Authority Commercial Executive Director Cissy Chan explained that temperature-controlled air freight is one of the fastest growing segments in the air cargo market.

She believes with the new certification, the airport is well-placed to capture the increasing growth opportunities in the market for fresh and perishable goods.

“With the opening of the Hong Kong-Zhuhai-Macao Bridge, the transport time between the airport and the Greater Bay Area, notably the western part of the Pearl River Delta, will be further cut down.

“So this will put us in an even better position to become the transhipment hub for these perishables for the entire bay area.”

Extra backing

To support the growing demand for perishables, the Airport Authority has provided additional cool dollies, so there are now more than 30 for use by the whole airport community. It is also building apron shelters to protect the perishables from ambient weather elements.

Cathay Pacific Cargo Service Delivery General Manager Frosti Lau said they would work closely with the authority and its cargo terminal to see what new investments are required to handle the increasing demand.

Residents may have seen a distinctive white car, fitted with advanced imaging and sensory gadgetry, on its journey to create the next generation of Hong Kong maps.

As it travels up and down the city’s streets, it records the three-dimensional shapes of buildings ranging from the iconic Convention & Exhibition Centre to the Customs Headquarters Building, and even primary school campuses.

The vehicle, dubbed the Mobile Mapping System, is one of the latest technologies used by the Lands Department to survey the city.

Five pieces of equipment work in concert to collect detailed information for the 3D City Map - a core component of the digital infrastructure underpinning Hong Kong’s smart city development.

A high-resolution camera on top of the vehicle captures 360-degree images and a 3D laser scanner collects spatial measurements. An inertial navigation system and a global navigation satellite system receiver provide precise positioning.

Lands Department Assistant Land Surveyor Charlie Hung said one of the biggest advantages of this system is its ability to quickly and efficiently acquire data, which can be used to enrich 3D models and enhance existing maps.

“We can enhance the attributed information of our basic map. For example, the lamppost number, the building name or the street number.”

Drones are also used to map the city, she added. However, air surveying may not be suitable for collecting data from ground level. This is where the Mobile Mapping System vehicle comes into play.

Better data

The 3D City Map is part of the 3D Digital Map Development, which aims to contribute to an innovative, sustainable and smart Hong Kong.

Compared with traditional maps, the 3D City Map can provide more accurate and abundantly better spatial data.

The map will cover the entire city by 2023, serving as a handy tool for analysis and planning, according to Lands Department Land Surveyor Ben Fan.

He said: “Based on the 3D digital map, we can develop various kinds of applications such as land administration, environmental assessment, town planning and also transport and engineering studies.”

The latest transport infrastructures such as the Hong Kong-Zhuhai-Macao Bridge, the Central-Wan Chai Bypass and the Heung Yuen Wai Highway have also been scanned.

In the next stage of the 3D Digital Map Development, the department will create the 3D Indoor Map. As a start, data from 150 buildings in Kowloon East will be collected first before extending to other buildings in the city.

The last stage 3D models of objects such as trees and lampposts for city modelling will be produced.

(JAMA Network) This randomized clinical trial looked at the effect of a face-aging mobile app on daily sunscreen use and other skin protection among teens in Brazil. Selfies of students were altered to show UV effects on their future faces and shown to their class, accompanied by information about sun protection. Reducing UV exposure in children and adolescents is important because of the increased risk of skin cancer with cumulative UV exposure and sunburns early in life.

(SCALE Nanotech) ESA-backed researchers demonstrate the laser-propulsion of graphene sails in microgravity. The light sails use a scalable micro-membrane design that minimizes their mass and hence increases their thrust upon light irradiation. To demonstrate the new sail concept, the scientists gained access to ZARM Drop Tower. There, the sail prototypes were set in vacuum and microgravity, and 1W-lasers caused their acceleration up to 1 m/s2.

(University of Michigan) The coronavirus pandemic has highlighted just how reliant the United States and other countries are on Chinese manufacturing, with widespread shortages of protective medical gear produced there.

(Tokyo University of Science) Plastic waste often ends up in river bodies and oceans, posing a serious threat to the marine ecosystem. To prevent the accumulation of plastic debris, we must find out where plastic emission is prevalent. To this end, scientists in Japan have come up with a new method to track plastic emissions from inland areas to sea. This method is useful to identify the 'hotspots' of plastic emission and can even help to implement appropriate measures to avoid plastic pollution.

(American Friends of Tel Aviv University) The research reveals that hunter-gatherer societies expressed a deep emotional and psychological connection with the animal species they hunted, especially after their disappearance. The study will help anthropologists and others understand the profound environmental changes taking place in our own lifetimes.

(Universitat Pompeu Fabra - Barcelona) Expansions by groups of humans were common during prehistoric times, after the adoption of agriculture. Among other factors, this is due to population growth of farmers which was greater than of that hunter-gatherers. We can find one example of this during the Neolithic period, when farming was introduced to Europe by migrations from the Middle East.
