Review of structural neuroimaging and genetic findings in autism spectrum disorder - a clinical perspective.

Autism spectrum disorders (ASDs) are neurodevelopmental conditions characterized by deficits in social relationships and communication and restrictive, repetitive behaviors and interests. ASDs form a heterogeneous group from a clinical and genetic perspective. Currently, ASDs diagnosis is based on the clinical observation of the individual's behavior.

Vacancy-Induced Tunable Kondo Effect in Twisted Bilayer Graphene.

In single sheets of graphene, vacancy-induced states have been shown to host an effective spin-1/2 hole that can be Kondo screened at low temperatures. Here, we show how these vacancy-induced impurity states survive in twisted bilayer graphene (TBG), which thus provides a tunable system to probe the critical destruction of the Kondo effect in pseudogap hosts. Ab initio calculations and atomic-scale modeling are used to determine the nature of the vacancy states in the vicinity of the magic angle in TBG, demonstrating that the vacancy can be treated as a quantum impurity.

Proximity induced charge density wave in a graphene/1T-TaS heterostructure.

The proximity-effect, whereby materials in contact appropriate each other's electronic-properties, is widely used to induce correlated states, such as superconductivity or magnetism, at heterostructure interfaces. Thus far however, demonstrating the existence of proximity-induced charge-density-waves (PI-CDW) proved challenging. This is due to competing effects, such as screening or co-tunneling into the parent material, that obscured its presence.

Periodontal changes induced by fixed orthodontic therapy.

Background: Orthodontic therapy is a complex process involving a series of specialists in the dental field: the oral-maxillo-facial surgeon, the periodontologist, sometimes even the prosthetist, implantologist, or general practitioners. The injuries of the oral mucosa induced by orthodontic therapy include gingival overgrowths, traumatic lesions of the oral mucosa, different degrees of periodontal damage manifested by gingival retraction, alveolar bone resorption.

Methods: From a total of 327 subjects who came to the Dental Clinic in Craiova 74 subjects were selected, who presented with gingival overgrowth associated with fixed orthodontic therapy.

Cryogen-free modular scanning tunneling microscope operating at 4-K in high magnetic field on a compact ultra-high vacuum platform.

One of the daunting challenges in modern low temperature scanning tunneling microscopy (STM) is the difficulty of combining atomic resolution with cryogen-free cooling. Further functionality needs, such as ultra-high vacuum (UHV), high magnetic field (HF), and compatibility with μm-sized samples, pose additional challenges to an already ambitious build. We present the design, construction, and performance of a cryogen-free, UHV, low temperature, and high magnetic field system for modular STM operation.
