  • Feng, Guoping; Ting, Jonathan Thomas (Elsevier, 2013-03)
    Here we review the rapidly growing toolbox of transgenic mice and rats that exhibit functional expression of engineered opsins for neuronal activation and silencing with light. Collectively, these transgenic animals are ...
  • Hu, Qing; Kumar, Sushil; Qin, Qi; Williams, Benjamin S.; Reno, John L. (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    We report a novel tuning mechanism based on a “wire-laser” with subwavelength transverse dimensions(w≪λ). By manipulating the waveguided mode propagating outside the cavity, frequency tuning of ∼137GHz (3.6%) is demonstrated ...
  • Raja, Waseem Khan; Padgen, Michael R.; Williams, James K.; Gertler, Frank; Wyckoff, Jeffrey B.; Condeelis, John S.; Castracane, James (2012-03)
    Cancer cells create a unique microenvironment in vivo that enables migration to distant organs. To better understand the tumor microenvironment, special tools and devices are required to monitor the interactions between ...
  • Hsieh, David; Wray, L. A.; Thomale, R.; Platt, C.; Qian, D.; Chen, G. F.; Luo, J. L.; Wang, N. L.; Hasan, M. Z. (American Physical Society, 2012-10)
    We present a polarization-resolved study of the low-energy band structure in the optimally doped iron pnictide superconductor Ba[subscript 0.6]K[subscript 0.4]Fe[subscript 2]As[subscript 2] (T[subscript c]=37 K) using ...
  • Peraud, Jean-Philippe Michel; Hadjiconstantinou, Nicolas (American Society of Mechanical Engineers (ASME), 2012-11)
    We present a new method for simulating phonon transport at the nanoscale. The proposed approach is based on the recently developed energy-based deviational Monte Carlo method by the authors [Phys. Rev. B 84, 205331, 2011] ...
  • Landon, Colin D.; Hadjiconstantinou, Nicolas (American Physical Society, 2014-10)
    We present a deviational Monte Carlo method for solving the Boltzmann-Peierls equation with ab initio 3-phonon scattering, for temporally and spatially dependent thermal transport problems in arbitrary geometries. Phonon ...
  • Heo, Myoung-Sun; Rvachov, Timur M.; Cotta, Dylan Alain; Ketterle, Wolfgang; Wang, Tout Taotao (American Physical Society, 2013-04)
    Collisions of [superscript 6]Li[subscript 2] molecules with free [superscript 6]Li atoms reveal a striking deviation from universal predictions based on long-range van der Waals interactions. Li[subscript 2] closed-channel ...
  • Wadhwa, Neal; Dekel, Tali; Wei, Donglai; Freeman, William T.; Durand, Fredo (Association for Computing Machinery (ACM), 2015-11)
    Structures and objects are often supposed to have idealized geometries such as straight lines or circles. Although not always visible to the naked eye, in reality, these objects deviate from their idealized models. Our ...
  • Bonkowski, Michael S.; Pointer, Kelli; Pletcher, Scott D.; Libert, Sergiy V.; Guarente, Leonard Pershing (Wiley Blackwell, 2012-07)
    The variation of individual life spans, even in highly inbred cohorts of animals and under strictly controlled environmental conditions, is substantial and not well understood. This variation in part could be due to ...
  • Mitchell, Bernhard; Altermatt, Pietro P.; Wagner, Hannes; Hofstetter, Jasmin; Buonassisi, Anthony (Elsevier, 2015-08)
    We present a numerical simulation study of different multicrystalline silicon materials and solar cell architectures to understand today's efficiency limitations and future efficiency possibilities. We compare conventional ...
  • Strauss, Jacob A.; Lesniewski-Laas, Christopher Tur; Paluska, Justin Mazzola; Ford, Bryan; Morris, Robert Tappan; Kaashoek, M. Frans (Association for Computing Machinery, 2010-01)
    This paper proposes a new storage model, device transparency, in which users view and manage their entire data collection from any of their devices, even from disconnected storage-limited devices holding only a subset of ...
  • Çağlar, Tolga; Berker, A Nihat (American Physical Society, 2017-04)
    The chiral clock spin-glass model with q=5 states, with both competing ferromagnetic-antiferromagnetic and left-right chiral frustrations, is studied in d=3 spatial dimensions by renormalization-group theory. The global ...
  • Kenny, Jonathan Dillion; Taylor, Norman E.; Brown, Emery N.; Solt, Ken (Public Library of Science, 2015-07)
    Methylphenidate induces reanimation (active emergence) from general anesthesia in rodents, and recent evidence suggests that dopaminergic neurotransmission is important in producing this effect. Dextroamphetamine causes ...
  • Gomez, Jose Alberto; Hoeffner, Kai; Barton, Paul I. (BioMed Central Ltd, 2014-12)
    Background: Dynamic Flux Balance Analysis (DFBA) is a dynamic simulation framework for biochemical processes. DFBA can be performed using different approaches such as static optimization (SOA), dynamic optimization (DOA), ...
  • White, Richard Mark; Cech, Jennifer N.; Ratanasirintrawoot, Sutheera; Lin, Charles Y.; Rahl, Peter B.; Burke, Christopher J.; Langdon, Erin; Tomlinson, Matthew L.; Mosher, Jack; Kaufman, Charles; Chen, Frank; Long, Hannah K.; Kramer, Martin; Datta, Sumon; Neuberg, Donna S.; Granter, Scott; Young, Richard A.; Morrison, Sean; Wheeler, Grant N.; Zon, Leonard I. (Nature Publishing Group, 2011-03)
    Melanoma is a tumour of transformed melanocytes, which are originally derived from the embryonic neural crest. It is unknown to what extent the programs that regulate neural crest development interact with mutations in the ...
  • Van Voorhis, Troy; Kowalczyk, Timothy Daniel; Kaduk, Benjamin James; Wang, Lee-Ping; Cheng, Chiao-Lun; Wu, Qin (Annual Reviews, 2010-05)
    Diabatic states have a long history in chemistry, beginning with early valence bond pictures of molecular bonding and extending through the construction of model potential energy surfaces to the modern proliferation of ...
  • French, Katherine L.; Tosca, Nicholas J.; Cao, Changqun; Summons, Roger Everett (Elsevier Ltd., 2012-05)
    Many biogeochemical anomalies coincide with the Late Permian Extinction (LPE; 252.28 Ma). Several mechanisms have been proposed to explain the moretane/hopane anomaly that has been identified in samples from Meishan GSSP ...
