Our sense of touch enables us to recognize texture and shape and to grasp objects. The challenge in making an electronic skin which can emulate touch for applications such as a humanoid robot or minimally invasive and remote surgery is both in mimicking the (passive) mechanical properties of the dermis and the characteristics of the sensing mechanism, especially the intrinsic digital nature of neurons. Significant progress has been made towards developing an electronic skin by using a variety of materials and physical concepts, but the challenge of emulating the sense of touch remains. Recently, a nanodevice was developed that has achieved the resolution to decipher touch on a par with the human finger; this resolution is over an order of magnitude improvement on previous devices with a sensing area larger than 1 cm(2). With its robust mechanical properties, this new system represents an important step towards the realization of artificial touch.

Localization and Spread of Challenging Conduction Gaps of Pulmonary Veins for Atrial Fibrillation Cryoablation.

Background: Cryoballoon ablation has been widely performed in patients with paroxysmal atrial fibrillation (AF). In some challenging pulmonary veins (PVs), the procedure requires additional touch-up applications against the residual conduction gaps. It implies that there could exist difficult sites to cover with standard cryoballoon applications (CBAs), resulting in resistant conduction gaps (RCGs).

Mirror-invariance enables recognition of mirrored objects as identical. During reading acquisition, sighted readers must overcome this innate bias to distinguish between mirror-inverted letters ('d' vs. 'b').

Background: Burkholderia cenocepacia complex is an important cause of hospital acquired infections. We describe the management of an outbreak in a neonatal intensive care unit (NICU) due to tap colonisation.
Methods: Microbiological testing of touch (n = 26) and non-touch taps (n = 28), sinks and drains, including genomic sequencing of selected isolates.
Behavior Coding of Adolescent and Therapy Dog Interactions During a Social Stress Task.

Youth mental health interventions incorporating trained therapy animals are increasingly popular, but more research is needed to understand the specific interactive behaviors between participants and therapy dogs. Understanding the role of these interactive behaviors is important for supporting both intervention efficacy and animal welfare and well-being. The goal of this study was to develop ethograms to assess interactive behaviors (including both affiliative and stress-related behaviors) of participants and therapy dogs during a social stress task, explore the relationship between human and dog behaviors, and assess how these behaviors may vary between experimental conditions with varying levels of physical contact with the therapy dog.

Background: Psoriasis is commonly associated with metabolic dysfunction-associated steatotic liver disease, raising concerns about the hepatic effects of systemic treatments on psoriasis and its comorbid conditions. This study evaluates liver stiffness measurement (LSM) alterations and identifies predictors of abnormal LSM in psoriatic patients following systemic treatments, including biologics and methotrexate.
Methods: This prospective cohort study is based on the PSOWCH database (Psoriasis Cohort of West China Hospital).
