There is a growing interest in the German thinker Arthur Schopenhauer (1788-1860), sometimes referred to as "the psychologist of the "will", but scarce empirical research has been conducted on the relevance of his philosophy for psychology and psychiatry. Following his death, philosophers, psychologists, psychiatrists, artists, writers, and natural scientists commended him. However, he was harshly criticized by others, notably by Friedrich Nietzsche and Martin Heidegger.

We carried out a comparison of the neuromuscular and clinical effects produced by electrostimulation therapies, as an adjuvant to the use of occlusal splints (removable muscle relaxation apparatus) in patients with temporomandibular disorders In this simple randomized clinical trial, 91 patients were randomly divided into three groups. Group A (GA) received transcutaneous electrostimulation therapy and an occlusal splint, Group B (GB) received percutaneous electrostimulation therapy and an occlusal splint, and Group C (GC) received an occlusal splint. The neuromuscular activity, as well as the signs and symptoms of each patient, were evaluated every week throughout the treatment (T0 = baseline; T1 = 7 days; T2 = 14 days; T3 = 21 days; T4 = 28 days; and T5 = 35 days).

We report the results of the investigation of bulk and surface acoustic phonons in the undoped and boron-doped single-crystal diamond films using the Brillouin-Mandelstam light scattering spectroscopy. The evolution of the optical phonons in the same set of samples was monitored with Raman spectroscopy. It was found that the frequency and the group velocity of acoustic phonons decrease nonmonotonically with the increasing boron doping concentration, revealing pronounced phonon softening.

Article Synopsis
  • The study investigates how the vibrational properties and interfacial structure influence thermal transport in wide band gap semiconductor systems, specifically examining interfaces between nitride metals and various semiconductor materials.
  • Time-domain thermoreflectance measurements reveal that conductance varies between materials, showing that while TiN interfaces are highly conductive, vibrational similarity alone doesn't guarantee high thermal conductance.
  • The research suggests that double thermal transport is largely influenced by the bulk phonon properties of the softer material and the specific structure of the interface, with interfacial disorder introducing significant thermal resistance.
