Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

ASRock has expanded its family of motherboards with the H81TM-ITX R2.0 model, designed for small form factor desktops, all-in-ones and home media centers.

The novelty has a Thin Mini-ITX size. Power can be supplied via a DC-In connector compatible with external adapters up to 19V. Without a bulky internal power supply, the motherboard can be placed in a very compact case.

The board is based on the entry-level Intel H81 Express chipset. It is allowed to install Core i7 / i5 / i3, Pentium and Celeron processors in LGA 1150 version with a maximum value of dissipated thermal energy up to 65 W.

There are two slots for DDR3-1600/1333/1066 RAM modules with a total capacity of up to 16 GB and two SATA 3.0 (6 Gb / s) ports for connecting drives. There are PCI-Express 2.0 x4 and mPCIe slots.

The board is equipped with a gigabit network controller and Realtek ALC892 7.1 audio codec. DVI-I and HDMI interfaces are displayed on the panel with connectors, two USB 3.0 and USB 2.0 ports with ESD protection, speaker and microphone jacks.

Of the proprietary solutions, the XFast RAM system is mentioned, which creates a virtual disk in the system memory to improve performance: at the same time, the speed of operations, for example, in Photoshop can increase 5 times. The XFast LAN tool enhances the performance of Internet applications.
