Conditional Entropy and Location Error in Indoor Localization Using Probabilistic Wi-Fi Fingerprinting.

Sensors (Basel, Switzerland)

Berkvens R, Peremans H, Weyn M.
PMID: 27706099
Sensors (Basel). 2016 Oct 02;16(10). doi: 10.3390/s16101636.

Localization systems are increasingly valuable, but their location estimates are only useful when the uncertainty of the estimate is known. This uncertainty is currently calculated as the location error given a ground truth, which is then used as a...

Ultrafast optical control of orbital and spin dynamics in a solid-state defect.

Science (New York, N.Y.)

Bassett LC, Heremans FJ, Christle DJ, Yale CG, Burkard G, Buckley BB, Awschalom DD.
PMID: 25123482
Science. 2014 Sep 12;345(6202):1333-7. doi: 10.1126/science.1255541. Epub 2014 Aug 14.

Atom-scale defects in semiconductors are promising building blocks for quantum devices, but our understanding of their material-dependent electronic structure, optical interactions, and dissipation mechanisms is lacking. Using picosecond resonant pulses of light, we study the coherent orbital and spin...

Phonon-induced diamagnetic force and its effect on the lattice thermal conductivity.

Nature materials

Jin H, Restrepo OD, Antolin N, Boona SR, Windl W, Myers RC, Heremans JP.
PMID: 25799325
Nat Mater. 2015 Jun;14(6):601-6. doi: 10.1038/nmat4247. Epub 2015 Mar 23.

Phonons are displacements of atoms around their rest positions in a crystalline solid. They carry sound and heat, but are not classically associated with magnetism. Here, we show that phonons are, in fact, sensitive to magnetic fields, even in...

Septicaemia And Endocarditis Due to Streptococci of Lancefield Group.

Acta clinica Belgica

Mascart G, Dutaye J, Feremans W.
PMID: 27373461
Acta Clin Belg. 1981 Jan;36(4):209-12. doi: 10.1080/22953337.1981.11718809.

Though beta haemolytic streptococci of Lancefield group B are important in the infectious pathology of the newborn, they are much less common in the adult and for this reason less well-known. In connection with a case of endocarditis due...

Observation of spin Seebeck contribution to the transverse thermopower in Ni-Pt and MnBi-Au bulk nanocomposites.

Nature communications

Boona SR, Vandaele K, Boona IN, McComb DW, Heremans JP.
PMID: 27941927
Nat Commun. 2016 Dec 12;7:13714. doi: 10.1038/ncomms13714.

Transverse thermoelectric devices produce electric fields perpendicular to an incident heat flux. Classically, this process is driven by the Nernst effect in bulk solids, wherein a magnetic field generates a Lorentz force on thermally excited electrons. The spin Seebeck...

Independent tuning of size and coverage of supported Pt nanoparticles using atomic layer deposition.

Nature communications

Dendooven J, Ramachandran RK, Solano E, Kurttepeli M, Geerts L, Heremans G, Rongé J, Minjauw MM, Dobbelaere T, Devloo-Casier K, Martens JA, Vantomme A, Bals S, Portale G, Coati A, Detavernier C.
PMID: 29057871
Nat Commun. 2017 Oct 20;8(1):1074. doi: 10.1038/s41467-017-01140-z.

Synthetic methods that allow for the controlled design of well-defined Pt nanoparticles are highly desirable for fundamental catalysis research. In this work, we propose a strategy that allows precise and independent control of the Pt particle size and coverage....

Energy Level Tuning of Non-Fullerene Acceptors in Organic Solar Cells.

Journal of the American Chemical Society

Cnops K, Zango G, Genoe J, Heremans P, Martinez-Diaz MV, Torres T, Cheyns D.
PMID: 26104833
J Am Chem Soc. 2015 Jul 22;137(28):8991-7. doi: 10.1021/jacs.5b02808. Epub 2015 Jul 10.

The use of non-fullerene acceptors in organic photovoltaic (OPV) devices could lead to enhanced efficiencies due to increased open-circuit voltage (VOC) and improved absorption of solar light. Here we systematically investigate planar heterojunction devices comprising peripherally substituted subphthalocyanines as...

Mechanical and Electronic Properties of Thin-Film Transistors on Plastic, and Their Integration in Flexible Electronic Applications.

Advanced materials (Deerfield Beach, Fla.)

Heremans P, Tripathi AK, de Jamblinne de Meux A, Smits EC, Hou B, Pourtois G, Gelinck GH.
PMID: 26707947
Adv Mater. 2016 Jun;28(22):4266-82. doi: 10.1002/adma.201504360. Epub 2015 Dec 28.

The increasing interest in flexible electronics and flexible displays raises questions regarding the inherent mechanical properties of the electronic materials used. Here, the mechanical behavior of thin-film transistors used in active-matrix displays is considered. The change of electrical performance...

Prolonged Walking with a Wearable System Providing Intelligent Auditory Input in People with Parkinson's Disease.

Frontiers in neurology

Ginis P, Heremans E, Ferrari A, Dockx K, Canning CG, Nieuwboer A.
PMID: 28428770
Front Neurol. 2017 Apr 06;8:128. doi: 10.3389/fneur.2017.00128. eCollection 2017.

Rhythmic auditory cueing is a well-accepted tool for gait rehabilitation in Parkinson's disease (PD), which can now be applied in a performance-adapted fashion due to technological advance. This study investigated the immediate differences on gait during a prolonged, 30...

Benzodiazepine receptor ligands have no specific action on working memory in a delayed conditional discrimination task in rats.

Behavioural pharmacology

Herremans AH, Hijzen TH, Olivier B, Slangen JL.
PMID: 11224332
Behav Pharmacol. 1995 Apr;6(3):238-244.

We investigated effects of benzodiazepine (BDZ) receptor ligands on working memory in a delayed conditional discrimination (DCD) task. The BDZ receptor full agonist midazolam (0.1-1.0mg/kg) dose-dependently impaired performance independent of delay, indicating no specific effect on working memory. The...

Observation of the spin-Seebeck effect in a ferromagnetic semiconductor.

Nature materials

Jaworski CM, Yang J, Mack S, Awschalom DD, Heremans JP, Myers RC.
PMID: 20871608
Nat Mater. 2010 Nov;9(11):898-903. doi: 10.1038/nmat2860. Epub 2010 Sep 26.

Reducing the heat generated in traditional electronics is a chief motivation for the development of spin-based electronics, called spintronics. Spin-based transistors that do not strictly rely on the raising or lowering of electrostatic barriers can overcome scaling limits in...
