2. 1. Emotional Communication in the Human Voice

   Author : Henrik Nordström; Petri Laukka; Marc Pell; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; emotion recognition; vocal expression; speech; acoustic parameters; Psychology; psykologi;

   Abstract : Emotional communication is an important part of social interaction because it gives individuals valuable information about the state of others, allowing them to adjust their behaviors and responses appropriately. When people use the voice to communicate, listeners do not only interpret the words that are said, the verbal content, but also the information contained in how the words are said, the nonverbal content.

   Abstract : Microdialysis has recently developed from a laboratory research method of animals to a useful clinical tool to evaluate parameters suggesting tissue ischemia. It is now used in neurosurgery, plastic surgery and liver transplantation. READ MORE

6. 4. Hierarchical energy management in smart grids : Flexibility prediction, scheduling and resilient control

   Author : Kaveh Paridari; Lars Nordström; Henrik Sandberg; Geert Deconinck; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

   Abstract : The electric power industry and society are facing challenges and opportunitiesof transforming the present power grid into a smart grid. Energymanagement systems (EMSs) play an important role in smart grids. A generalhierarchical structure for EMSs is considered here, which is composed ofa lower layer and an upper layer. READ MORE

7. 5. Glutamate Turnover and Energy Metabolism in Brain Injury : Clinical and Experimental Studies

   Author : Carolina Samuelsson; Elisabeth Ronne-Engström; Lars Hillered; Eva Kumlien; Carl-Henrik Nordström; Uppsala universitet; []
   Keywords : Neurosciences; glutamate; glutamine; lactate; pyruvate; microdialysis; GLT-1; energy metabolism; intracranial pressure; cerebral perfusion pressure; subarachnoid hemorrhage; ischemia; epilepsy; Neurovetenskap;

   Abstract : During brain activity neurons release the major excitatory transmitter glutamate, which is taken up by astrocytes and converted to glutamine. Glutamine returns to neurons for re-conversion to glutamate. This glutamate-glutamine cycle is energy demanding. READ MORE
