Robust spot-poled membrane hydrophones for measurement of large amplitude pressure waveforms generated by high intensity therapeutic ultrasonic transducers.

The Journal of the Acoustical Society of America

Wilkens V, Sonntag S, Georg O.
PMID: 27036269
J Acoust Soc Am. 2016 Mar;139(3):1319-32. doi: 10.1121/1.4944693.

The output characterization of medical high intensity therapeutic ultrasonic devices poses several challenges for the hydrophones to be used for pressure measurements. For measurements at clinical levels in the focal region, extreme robustness, broad bandwidth, large dynamic range, and...

Determinants for Sustained Use of an Activity Tracker: Observational Study.

JMIR mHealth and uHealth

Hermsen S, Moons J, Kerkhof P, Wiekens C, De Groot M.
PMID: 29084709
JMIR Mhealth Uhealth. 2017 Oct 30;5(10):e164. doi: 10.2196/mhealth.7311.

BACKGROUND: A lack of physical activity is considered to cause 6% of deaths globally. Feedback from wearables such as activity trackers has the potential to encourage daily physical activity. To date, little research is available on the natural development...

Therapeutics and clinical risk management

Mestres Gonzalvo C, Hurkens KP, de Wit HA, van Oijen BP, Janknegt R, Schols JM, Mulder WJ, Verhey FR, Winkens B, van der Kuy PH.
PMID: 26056459
Ther Clin Risk Manag. 2015 May 08;11:767-77. doi: 10.2147/TCRM.S77428. eCollection 2015.

BACKGROUND: The aim of this study was to evaluate to what extent laboratory data, actual medication, medical history, and/or drug indication influence the quality of medication reviews for nursing home patients.METHODS: Forty-six health care professionals from different fields were...

Structure and mechanism of ABC transporters.

F1000prime reports

Wilkens S.
PMID: 25750732
F1000Prime Rep. 2015 Feb 03;7:14. doi: 10.12703/P7-14. eCollection 2015.

All living organisms depend on primary and secondary membrane transport for the supply of external nutrients and removal or sequestration of unwanted (toxic) compounds. Due to the chemical diversity of cellular molecules, it comes as no surprise that a...

Controlling the physics and chemistry of binary and ternary praseodymium and cerium oxide systems.

Physical chemistry chemical physics : PCCP

Niu G, Zoellner MH, Schroeder T, Schaefer A, Jhang JH, Zielasek V, Bäumer M, Wilkens H, Wollschläger J, Olbrich R, Lammers C, Reichling M.
PMID: 26355535
Phys Chem Chem Phys. 2015 Oct 14;17(38):24513-40. doi: 10.1039/c5cp02283e.

Rare earth praseodymium and cerium oxides have attracted intense research interest in the last few decades, due to their intriguing chemical and physical characteristics. An understanding of the correlation between structure and properties, in particular the surface chemistry, is...

Classical information and distillable entanglement.

Physical review letters

Eisert J, Felbinger T, Papadopoulos P, Plenio MB, Wilkens M.
PMID: 11017580
Phys Rev Lett. 2000 Feb 14;84(7):1611-4. doi: 10.1103/PhysRevLett.84.1611.

We establish a quantitative connection between the amount of lost classical information about a quantum state and the concomitant loss of entanglement. Using methods that have been developed for the optimal purification of mixed states, we find a class...

Characterization of an optical multilayer hydrophone with constant frequency response in the range from 1 to 75 MHz.

The Journal of the Acoustical Society of America

Wilkens V.
PMID: 12656378
J Acoust Soc Am. 2003 Mar;113(3):1431-8. doi: 10.1121/1.1553457.

The performance of an optical multilayer hydrophone for ultrasound measurements is investigated both in theoretical terms and experimentally. The optical measurement system comprises a thin high-finesse dielectric interference filter structure that is deposited onto a plane glass plate. An...

Synthesis of periphery-functionalized dendritic molecules using polylithiated dendrimers as starting material.

Organic letters

Wijkens P, Jastrzebski JT, van Der Schaaf PA, Kolly R, Hafner A, van Koten G.
PMID: 10841494
Org Lett. 2000 Jun 01;2(11):1621-4. doi: 10.1021/ol0059100.

A general method for the functionalization of Si-Cl terminated carbosilane dendritic molecules via organolithium or organomagnesium reagents is described. Quantitative exchange of the bromine atoms of 4-bromophenyl-functionalized dendrimers affords polylithiated species that are valuable starting materials for further functionalization,...

Recall of a lead-contaminated vitamin and mineral supplement in a clinical trial.

Pharmacoepidemiology and drug safety

Rogan WJ, Ragan NB, Damokosh AI, Davoli C, Shaffer TR, Jones RL, Wilkens S, Heenehan MC, Ware JH, Henretig F.
PMID: 15073911
Pharmacoepidemiol Drug Saf. 1999 Aug;8(5):343-50. doi: 10.1002/(SICI)1099-1557(199908/09)8:5<343::AID-PDS440>3.0.CO;2-Q.

PURPOSE: The Treatment of Lead-exposed Children (TLC) trial tested whether developmental outcome differed between children treated for lead poisoning with succimer or placebo. On 7 July 1997, TLC was informed that the vitamin and mineral supplements it gave to...

Cortical cell assemblies: a possible mechanism for motor programs.

Journal of motor behavior

Wickens J, Hyland B, Anson G.
PMID: 15753061
J Mot Behav. 1994 Jun;26(2):66-82. doi: 10.1080/00222895.1994.9941663.

The concept of a motor program has been used to interpret a diverse range of empirical findings related to preparation and initiation of voluntary movement. In the absence of an underlying mechanism, its exploratory power has been limited to...
