Plant density can increase invertebrate postdispersal seed predation in an experimental grassland community.

Ecology and evolution

Dudenhöffer JH, Pufal G, Roscher C, Klein AM.
PMID: 27231530
Ecol Evol. 2016 May 06;6(11):3796-3807. doi: 10.1002/ece3.2039. eCollection 2016 Jun.

Janzen-Connell effects are negative effects on the survival of a plant's progeny at high conspecific densities or close to its conspecifics. Although the role of Janzen-Connell effects on the maintenance of plant diversity was frequently studied, only few studies...

Fostering Formal Commutativity Knowledge with Approximate Arithmetic.

PloS one

Hansen SM, Haider H, Eichler A, Godau C, Frensch PA, Gaschler R.
PMID: 26560311
PLoS One. 2015 Nov 11;10(11):e0142551. doi: 10.1371/journal.pone.0142551. eCollection 2015.

How can we enhance the understanding of abstract mathematical principles in elementary school? Different studies found out that nonsymbolic estimation could foster subsequent exact number processing and simple arithmetic. Taking the commutativity principle as a test case, we investigated...

Designing PbSe nanowires and nanorings through oriented attachment of nanoparticles.

Journal of the American Chemical Society

Cho KS, Talapin DV, Gaschler W, Murray CB.
PMID: 15884956
J Am Chem Soc. 2005 May 18;127(19):7140-7. doi: 10.1021/ja050107s.

Single-crystal PbSe nanowires are synthesized in solution through oriented attachment of nanocrystal building blocks. Reaction temperatures of 190-250 degrees C and multicomponent surfactant mixtures result in a nearly defect-free crystal lattice and high uniformity of nanowire diameter along the...

Cold atom dynamics in a quantum optical lattice potential.

Physical review letters

Maschler C, Ritsch H.
PMID: 16486317
Phys Rev Lett. 2005 Dec 31;95(26):260401. doi: 10.1103/PhysRevLett.95.260401. Epub 2005 Dec 19.

We study a generalized cold atom Bose-Hubbard model, where the periodic optical potential is formed by a cavity field with quantum properties. On the one hand, the common coupling of all atoms to the same mode introduces cavity-mediated long-range...

What I Say is What I Get: Stronger Effects of Self-Generated vs. Cue-Induced Expectations in Event-Related Potentials.

Frontiers in psychology

Kemper M, Umbach VJ, Schwager S, Gaschler R, Frensch PA, Stürmer B.
PMID: 23403896
Front Psychol. 2012 Dec 14;3:562. doi: 10.3389/fpsyg.2012.00562. eCollection 2012.

Expectations regarding future events enable preparatory processes and allow for faster responses to expected stimuli compared to unexpected stimuli. Expectations can have internal sources or follow external cues. While many studies on expectation effects use some form of cueing,...

Implicit learning of what comes when and where within a sequence: The time-course of acquiring serial position-item and item-item associations to represent serial order.

Advances in cognitive psychology

Schuck NW, Gaschler R, Frensch PA.
PMID: 22679464
Adv Cogn Psychol. 2012;8(2):83-97. doi: 10.2478/v10053-008-0106-0. Epub 2012 May 21.

Much research has been conducted aimed at the representations and mechanisms that enable learning of sequential structures. A central debate concerns the question whether item-item associations (i.e., in the sequence A-B-C-D, B comes after A) or associations of item...

Does explicit expectation really affect preparation?.

Frontiers in psychology

Umbach VJ, Schwager S, Frensch PA, Gaschler R.
PMID: 23248606
Front Psychol. 2012 Oct 01;3:378. doi: 10.3389/fpsyg.2012.00378. eCollection 2012.

Expectation enables preparation for an upcoming event and supports performance if the anticipated situation occurs, as manifested in behavioral effects (e.g., decreased RT). However, demonstrating coincidence between expectation and preparation is not sufficient for attributing a causal role to...

Tumor-associated copy number changes in the circulation of patients with prostate cancer identified through whole-genome sequencing.

Genome medicine

Heitzer E, Ulz P, Belic J, Gutschi S, Quehenberger F, Fischereder K, Benezeder T, Auer M, Pischler C, Mannweiler S, Pichler M, Eisner F, Haeusler M, Riethdorf S, Pantel K, Samonigg H, Hoefler G, Augustin H, Geigl JB, Speicher MR.
PMID: 23561577
Genome Med. 2013 Apr 05;5(4):30. doi: 10.1186/gm434. eCollection 2013.

BACKGROUND: Patients with prostate cancer may present with metastatic or recurrent disease despite initial curative treatment. The propensity of metastatic prostate cancer to spread to the bone has limited repeated sampling of tumor deposits. Hence, considerably less is understood...
