The global diversity of birds in space and time

diversity

Jetz W, Thomas GH, Joy JB, Hartmann K, Mooers AO.
GSID: LMF9xMWWOvIJ
W Jetz, GH Thomas, JB Joy, K Hartmann, AO Mooers - Nature, 2012 - nature.com

Current global patterns of biodiversity result from processes that operate over both space and time and thus require an integrated macroecological and macroevolutionary perspective 1, 2, 3, 4. Molecular time trees have advanced our understanding of the tempo and...

Development and investigation of a long-range time-of-flight and color imaging system.

IEEE transactions on cybernetics

Langmann B, Weihs W, Hartmann K, Loffeld O.
PMID: 24235261
IEEE Trans Cybern. 2014 Aug;44(8):1372-82. doi: 10.1109/TCYB.2013.2283971. Epub 2013 Oct 16.

Time-of-flight (Tof) imaging based on the photonic mixer device (PMD) or similar ToF imaging solutions has been limited to short distances in the past, due to limited lighting devices and low sensitivity of ToF imaging chips. Long-range distance measurements...

The giant impact hypothesis: past, present (and future?).

Philosophical transactions. Series A, Mathematical, physical, and engineering sciences

Hartmann WK.
PMID: 25114315
Philos Trans A Math Phys Eng Sci. 2014 Sep 13;372(2024):20130249. doi: 10.1098/rsta.2013.0249.

At the request of editors, this paper offers a historical review of early work on the giant impact hypothesis, as well as comments on new data. The author hereby claims (whether believable or not) that his interest is to...

Gastric bulging confirmed as a pancreatic solid pseudopapillary tumor by endoscopic ultrasound-guided fine needle aspiration.

Endoscopic ultrasound

Lopes CV, Hartmann AA, Almeida RF, Weiss PB.
PMID: 28621302
Endosc Ultrasound. 2017 May-Jun;6(3):212-214. doi: 10.4103/2303-9027.208175.

A persistent northern boundary of Indian Summer Monsoon precipitation over Central Asia during the Holocene.

Scientific reports

Ramisch A, Lockot G, Haberzettl T, Hartmann K, Kuhn G, Lehmkuhl F, Schimpf S, Schulte P, Stauch G, Wang R, Wünnemann B, Yan D, Zhang Y, Diekmann B.
PMID: 27173918
Sci Rep. 2016 May 13;6:25791. doi: 10.1038/srep25791.

Extra-tropical circulation systems impede poleward moisture advection by the Indian Summer Monsoon. In this context, the Himalayan range is believed to insulate the south Asian circulation from extra-tropical influences and to delineate the northern extent of the Indian Summer...

Number of guards needed by a museum: a phase transition in vertex covering of random graphs.

Physical review letters

Weigt M, Hartmann AK.
PMID: 10991138
Phys Rev Lett. 2000 Jun 26;84(26):6118-21. doi: 10.1103/PhysRevLett.84.6118.

In this Letter we study the NP-complete vertex cover problem on finite connectivity random graphs. When the allowed size of the cover set is decreased, a discontinuous transition in solvability and typical-case complexity occurs. This transition is characterized by...

Immunotoxicity of gallium arsenide on antigen presentation: comparative study of intratracheal and intraperitoneal exposure routes.

Journal of immunotoxicology

Hartmann CB, Harrison MT, McCoy KL.
PMID: 18958654
J Immunotoxicol. 2005 Jan 01;2(1):1-9. doi: 10.1080/15476910590930083.

Gallium arsenide (GaAs) is a semiconductor utilized in electronics and computer industries. GaAs exposure of animals causes local inflammation and systemic immune suppression. Mice were administered 2 to 200 mg/kg GaAs. On day 5, intratracheal instillation increased lung weights...

Calculation of partition functions by measuring component distributions.

Physical review letters

Hartmann AK.
PMID: 15783622
Phys Rev Lett. 2005 Feb 11;94(5):050601. doi: 10.1103/PhysRevLett.94.050601. Epub 2005 Feb 07.

A new algorithm is presented, which allows us to calculate numerically the partition function Z for systems, which can be described by arbitrary interaction graphs and lattices, e.g., Ising models or Potts models (for arbitrary values q>0), including random...
