Full Aging in Spin Glasses

, 2003
The discovery of memory effects in the magnetization decays of spin glasses in 1983 began a large effort to determine the exact nature of the decay. While qualitative arguments have suggested that the decay functions should scale as $t_{w}$, the only ...

Steps towards the development of an experimentally verified simulation of pool nucleate boiling on a silicon wafer with artificial sites [PDF]

, 2009
Nucleate boiling is a very effective heat transfer cooling process, used in numerous industrial applications. Despite intensive research over decades, a reliable model of nucleate pool boiling is still not available.

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement

Advanced Science, EarlyView.
This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

Advanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Houston, We Have a Problem: Effects of Technical Frustration on Student Learning in Physics Laboratories [PDF]

, 2013
This study investigates the effect of laboratory work’s typical technical difficulties on student learning in the physical science classroom. Certainly the educational strategies of text and lecture are sorely lacking.

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, EarlyView.
Doehl et al. discovered an adaptive neuroimmune mechanism that induces itch in tick‐exposed guinea pigs, enabling rapid tick removal. This itch‐induced tick removal (IITR) is mediated by an adaptive cellular immune response and is independent of IgG, IgE, or TRPV1.

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Su Hippon. fr. 180 Dg. (= 171 W.²)

Lexis
Hipponax’s compound word χειρόχωλος (fr. 180 Dg.) could be read as an image-kenning used to define not only a miser, but also a πτωχός, as the comparison with Aristoph. Eq. 1080-5 seems to suggest.
