Phase transitions in semidefinite relaxations [Applied Mathematics]

19-Apr-2016 | Adel Javanmard; Andrea Montanari; Federico Ricci-Tersenghi, Proceedings of the National Academy of Sciences current issue, 2016

Statistical inference problems arising within signal processing, data mining, and machine learning naturally give rise to hard combinatorial optimization problems. These problems become intractable when the dimensionality of the data is large, as is often the case for modern datasets. A popular ...

Correction for Venton, Inner Workings: Exploring ancient storms in marshes, corals, and caves [Correction]

19-Apr-2016 | Proceedings of the National Academy of Sciences current issue, 2016

INNER WORKINGS Correction for “Inner Workings: Exploring ancient storms in marshes, corals, and caves,” by Danielle Venton, which appeared in issue 12, March 22, 2016, of Proc Natl Acad Sci USA (113:3125–3126; 10.1073/pnas.1600798113). The editors note that ref. 5 appeared incorrectly. The ...

A neural link between affective understanding and interpersonal attraction [Psychological and Cognitive Sciences]

19-Apr-2016 | Silke Anders; Roos de Jong; Christian Beck; John-Dylan Haynes; Thomas Ethofer, Proceedings of the National Academy of Sciences current issue, 2016

Being able to comprehend another person’s intentions and emotions is essential for successful social interaction. However, it is currently unknown whether the human brain possesses a neural mechanism that attracts people to others whose mental states they can easily understand. Here we show that ...

Insight into GATA1 transcriptional activity through interrogation of cis elements disrupted in human erythroid disorders [Genetics]

19-Apr-2016 | Aoi Wakabayashi; Jacob C. Ulirsch; Leif S. Ludwig; Claudia Fiorini; Makiko Yasuda; Avik Choudhuri; Patrick McDonel; ..., Proceedings of the National Academy of Sciences current issue, 2016

Whole-exome sequencing has been incredibly successful in identifying causal genetic variants and has revealed a number of novel genes associated with blood and other diseases. One limitation of this approach is that it overlooks mutations in noncoding regulatory elements. Furthermore, the ...

Anthropogenic aerosols are a potential cause for migration of the summer monsoon rain belt in China [Physical Sciences]

19-Apr-2016 | Shaocai Yu; Pengfei Li; Liqiang Wang; Peng Wang; Si Wang; Shucheng Chang; Weiping Liu; Kiran Alapaty, Proceedings of the National Academy of Sciences current issue, 2016

It has been proposed that the current and future global warming caused by increased greenhouse gases can produce a northward shift of the Earth’s rain belt (1). This conclusion is supported by a recent study in PNAS by Yang et al. (2) in which the carbon isotope composition of 21...

Tracking brain arousal fluctuations with fMRI [Neuroscience]

19-Apr-2016 | Catie Chang; David A. Leopold; Marieke Louise Schölvinck; Hendrik Mandelkow; Dante Picchioni; Xiao Liu; Frank Q. Ye; ..., Proceedings of the National Academy of Sciences current issue, 2016

Changes in brain activity accompanying shifts in vigilance and arousal can interfere with the study of other intrinsic and task-evoked characteristics of brain function. However, the difficulty of tracking and modeling the arousal state during functional MRI (fMRI) typically precludes the ...

Interallelic interaction and gene regulation in budding yeast [Genetics]

19-Apr-2016 | Daoyong Zhang; Lu Bai, Proceedings of the National Academy of Sciences current issue, 2016

In Drosophila, homologous chromosome pairing leads to “transvection,” in which the enhancer of a gene can regulate the allelic transcription in trans. Interallelic interactions were also observed in vegetative diploid budding yeast, but their functional significance is unknown. Here, we show that ...

Transmission dynamics of Ebola virus disease and intervention effectiveness in Sierra Leone [Medical Sciences]

19-Apr-2016 | Li-Qun Fang; Yang Yang; Jia-Fu Jiang; Hong-Wu Yao; David Kargbo; Xin-Lou Li; Bao-Gui Jiang; Brima Kargbo; Yi-Gang To ..., Proceedings of the National Academy of Sciences current issue, 2016

Sierra Leone is the most severely affected country by an unprecedented outbreak of Ebola virus disease (EVD) in West Africa. Although successfully contained, the transmission dynamics of EVD and the impact of interventions in the country remain unclear. We established a database of confirmed and ...

Coastal landforms and accumulation of mangrove peat increase carbon sequestration and storage [Environmental Sciences]

19-Apr-2016 | Paula Ezcurra; Exequiel Ezcurra; Pedro P. Garcillán; Matthew T. Costa; Octavio Aburto-Oropeza, Proceedings of the National Academy of Sciences current issue, 2016

Given their relatively small area, mangroves and their organic sediments are of disproportionate importance to global carbon sequestration and carbon storage. Peat deposition and preservation allows some mangroves to accrete vertically and keep pace with sea-level rise by growing on their own ...

Proteus mirabilis fimbriae- and urease-dependent clusters assemble in an extracellular niche to initiate bladder stone formation [Microbiology]

19-Apr-2016 | Jessica N. Schaffer; Allison N. Norsworthy; Tung-Tien Sun; Melanie M. Pearson, Proceedings of the National Academy of Sciences current issue, 2016

The catheter-associated uropathogen Proteus mirabilis frequently causes urinary stones, but little has been known about the initial stages of bladder colonization and stone formation. We found that P. mirabilis rapidly invades the bladder urothelium, but generally fails to establish an ...
