2. 1. Quantum acoustics with propagating phonons

   Author : Maria Ekström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phonon router; unidirectional transducer; phonon; Electromagnetically Induced Transparency; Surface acoustic wave; artificial atom; interdigital transducer; quantum acoustics; qubit; superconducting circuits;

   Abstract : Surface acoustic waves (SAWs) are mechanical vibrations that propagate on the surface of solids while dissipating little power, consequently enabling them to propagate freely over long distances. The speed and wavelength of SAWs are reduced a five order of magnitude compared to when light is used as a carrier at gigahertz frequencies. READ MORE

4. 2. Towards measuring quantum sound

   Author : Maria Ekström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; surface acoustic wave; interdigital transducer; artificial atom; qubit; superconducting circuits; cryogenic temperature; phonon; gigahertz frequency; quantum acoustics; unidirectional transducer;

   Abstract : One of the most fundamental phenomena occurring in nature is the interaction between single atoms and electromagnetic fields. This is studied in quantum optics to probe the quantum nature of the system. In appended Paper I, we demonstrated that an artificial atom can couple to propagating sound, which is the acoustic analogue of quantum optics. READ MORE

5. 3. Human olfaction : Associations with longitudinal assessment of episodic memory, dementia, and mortality risk

   Author : Ingrid Ekström; Jonas Olofsson; Maria Larsson; Devangere Devanand; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; olfaction; odor identification; self-assessments; aging; episodic memory; ApoE; dementia; Alzheimer’s disease; vascular dementia; mortality; cohort study; population-based.; Psychology; psykologi;

   Abstract : A declining sense of smell is a common feature in older age. Above and beyond diminished smelling capacity due to normal processes of human aging, impairments in olfactory function have also been linked to numerous ill-health related outcomes, such as cognitive dysfunctions, dementia pathology and even an increased risk of death.

6. 4. Towards Predictable and Reliable Wireless Communication in Harsh Environments

   Author : Martin Ekström; Maria Lindén; Dag Stranneby; Mälardalens högskola; []
   Keywords : Wireless; Reliable; predictable; Bluetooth; Zigbee; hardware development; measurements; elektronik; Electronics;

   Abstract : Wireless communication in industrial, scientific and medical applications have several benefits. The main benefits when using wireless technologies include ease-of-deployment, the simplicity to introduce new units into the network and mobility. READ MORE

7. 5. Det besvärliga våldet : Socialtjänstens stöd till kvinnor som utsatts för våld i nära relationer

   Author : Veronica Ekström; Martin Börjeson; Magnus Karlsson; Maria Eriksson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social work; social services; domestic violence; need interpretations; street-level bureaucrats.; Socialtjänst; våld i nära relationer; gatubyråkrater; behovstolkningar;

   Abstract : I avhandlingen analyseras hur våldsutsatta kvinnors behov tolkas, omförhandlas och anpassas för att kunna hanteras inom socialtjänstens organisation. Avhandlingens övergripande frågeställningar fokuserar på insatser och behov, betydelsen av socialtjänstens organisering och betydelsen av socialarbetarnas handlingsutrymme. READ MORE
