Endogeneity in Residential Location Choice Models (2006)

Empirical residential location choice models have occasionally reported estimated coefficients of dwelling-unit price that are small, statistically insignificant, or even positive. This would imply that households are insensitive to changes in dwelling-unit prices and taxes; this not only is counterintuitive but makes the models useless for policy analysis. One explanation for this result is price endogeneity, which means that the included dwelling unit's price variable is correlated with the model's error term. In discrete choice models this problem is caused principally by the omission of attributes correlated with price. An application of the control-function method is presented as the most suitable to correct for endogeneity in choice models of residential location. The method is tested for robustness to different error structures by using two Monte Carlo experiments, and it is also applied to real data from Santiago, Chile. The results show that price endogeneity is significant in choice models of residential location and that the control function method is suitable to account for it.
Using one-sided RDMA reads to build a fast, CPU-efficient key-value store (2013)

Recent technological trends indicate that future datacen-ter networks will incorporate High Performance Com-puting network features, such as ultra-low latency and CPU bypassing. How can these features be exploited in datacenter-scale systems infrastructure? In this pa-per, we explore the design of a distributed in-memory key-value store called Pilaf that takes advantage of Re-mote Direct Memory Access to achieve high perfor-mance with low CPU overhead. In Pilaf, clients directly read from the server’s mem-ory via RDMA to perform gets, which commonly dominate key-value store workloads. By contrast, put operations are serviced by the server to simplify the task of synchronizing memory accesses. To detect in-consistent RDMA reads with concurrent CPU memory modifications, we introduce the notion of self-verifying data structures that can detect read-write races without client-server coordination. Our experiments show that Pilaf achieves low latency and high throughput while consuming few CPU resources. Specifically, Pilaf can surpass 1.3 million ops/sec (90 % gets) using a single CPU core compared with 55K for Memcached and 59K for Redis. 1

Luminescent LaF3:Ce-doped organically modified nanoporous silica xerogels (2013)

Organically modified silica compounds (ORMOSILs) were synthesized by a sol-gel method from amine-functionalized 3-aminopropyl triethoxylsilane and tetramethylorthosilicate and were doped in situ with LaF3:Ce nanoparticles, which in turn were prepared either in water or in ethanol. Doped ORMOSILs display strong photoluminescence either by UV or X-ray excitation and maintain good transparency up to a loading level of 15.66% w/w. The TEM observations demonstrate that ORMOSILs remain nanoporous with pore diameters in the 5–10 nm range. LaF3:Ce nanoparticles doped into the ORMOSILs are rod-like, 5 nm in diameter and 10–15 nm in length. Compression testing indicates that the nanocomposites have very good strength, without significant lateral dilatation and buckling under quasi-static compression. LaF3:Ce nanoparticle-doped ORMOSILs have potential for applications in radiation detection and solid state lighting.
Function ofPseudomonasPorins in Uptake and Efflux (2002)

Porins are proteins that form water-filled channels across the outer membranes of Gram-negative bacteria and thus make this membrane semipermeable. There are four types of porins: general/nonspecific porins, substrate-specific porins, gated porins, and efflux porins (also called channel-tunnels). The recent publication of the genomic sequence of Pseudomonas aeruginosa PAO1 has dramatically increased our understanding of the porins of this organism. In particular this organism has 3 large families of porins: the OprD family of specific porins (19 members), the OprM family of efflux porins (18 members), and the TonB-interacting family of gated porins (35 members). These familial relationships underlie functional similarities such that well-studied members of these families become prototypes for other members. We summarize here the latest information on these porins.
Domain Structure‐Second Harmonic Generation Correlation in Potassium Niobate Thin Films Deposited on a Strontium Titanate Substrate (1996)

The experimental measurement of second harmonic generation (SHG) and theoretical correlation of the SHG output to domain microstructure is presented for ferroelectric KNbO 3 (110) thin films on a SrTiO 3 (100) substrate. From X‐ray diffraction, four possible domain variants in the film growth plane were determined to be KNbO 3 [1 1 0]∥SrTiO 3 [001], [00 1 ], [010], or [0 1 0] denoted as variants X +, X −, Y +, and Y −, respectively. From theoretical modeling of the SHG output from the film, the ratios of nonlinear coefficients d o /d 32 and d 24 /d 0 in the film were determined to be 2.19 ± 0.12 and 0.46 ± 0.26, respectively, in good agreement with the bulk KNbO 3 crystals. The term d 0 is defined as d 15 + (d 31 + d 33 )/2 . The SHG can also distinguish between X+ and X– , as well as Y+ and Y– , domains, which was not possible by X‐ray diffraction. The ratio of net area fraction (| A X+ − A X− |/| A Y+ − A Y− |) was determined to be 2.76 ± 1.06 in the probe area (2.25π mm 2 ) where A x+ , A x‐ , A Y+ , and A Y− are the area fractions of domain variants X+, X−, Y+ , and Y− , respectively, in the film growth plane.
Multicomponent Reactions in Polymer Chemistry Utilizing Heavier Main Group Elements (2020)

Herein, a concise overview of the use of heavier main group elements in multicomponent reactions and their use in polymer chemistry is provided. Incorporating heavier elements into macromolecular structures via multicomponent reactions allows for the rapid development of materials with unique properties that are not readily achieved using carbon, nitrogen, and/or oxygen. Elements in Group 13, Group 14, Group 15, and Group 16 are specifically covered examining both the familiar and unfamiliar properties of these elements and how they are used in multicomponent chemistry. Furthermore, elements that both take part in the reaction mechanism and remain in the macromolecular structure upon completion are only briefly explored. Some of the state-of-the-art work going into developing these heavier element multicomponent reactions are highlighted and it is hoped to inspire other polymer chemists to explore other parts of the periodic table.
Secretion of Vasopressin, Oxytocin, and Two Neurophysins from Rat Hypothalamo-Neurohypophyseal Explants in Organ Culture (1986)

Secretion of the neurohypophyseal principles arginine vasopressin, oxytocin, vasopressin-neurophysin, and oxytocin-neurophysin by hypothalamic-neurohypophyseal explants in organ culture was studied. The viability of explant cultures was tested on day 6 by their ability to incorporate 3H-amino acid into acid-precipitable protein, specifically vasopressin-neurophysin. The explants released all four neurosecretory products in a controlled manner during 8 successive days of culture. In addition, these substances were all present in neural lobes and hypothalami at the end of the culture period. Although the tissue retained a 1:1 molar ratio between the hormone and corresponding neurophysin, the levels of neurophysins in culture media were much higher than the levels of hormones. Through immunoprecipitation techniques we determined that both arginine vasopressin and oxytocin were unstable in culture media containing explants or in medium containing 10% heat-inactivated fetal calf serum. This suggests that neurophysins are more stable indicators of secretion by explants than are the corresponding hormones. An increased release of arginine vasopressin, oxytocin, vasopressin-neurophysin, and oxytocin-neurophysin occurred in response to elevated K+ and to increased sodium ions in the medium, and these four substances were released in different molecular proportions. The results indicate that explant cultures may be useful for comparisons of secretion of the two neurophysins and, to a more limited extent, of the two hormones in response to such stimuli.

Towards usage control models: beyond traditional access control (2002)

In this paper we develop the concept of Usage Control (UCON) that encompasses traditional access control, trust management, and digital rights management and goes beyond them in its definition and scope. While usage control concepts have been mentioned off and on in the security literature for some time, there has been no systematic treatment so far. By unifying these three areas UCON offers a promising approach for the next generation of access control. Traditional access control has focused on a closed system where all users are known and primarily utilizes a server-side reference monitor within the system. Trust management has been introduced to cover authorization for strangers in an open environment such as the Internet. Digital rights management has dealt with client-side control of digital information usage. Each of these areas is motivated by its own target problems. Innovations in information technology and business models are creating new security and privacy issues which require elements of all three areas. To deal with these in a systematic unified manner we propose the new UCON model. UCON enables finer-grained control over usage of digital objects than that of traditional access control policies and models. For example, print once as opposed to unlimited prints. Unlike traditional access control or trust management, it covers both centrally controllable environment and an environment where central control authority is not available. UCON also deals with privacy issues in both commercial and non-commercial environments. In this paper we first discuss access control, trust management, and digital rights management and describe general concepts of UCON in the information security discipline. Then we define components of the UCON model and discuss how authorizations and access controls can be applied in the UCON model. Next we demonstrate some applications of the UCON model and develop further details. We use several examples during these discussions to show the relevance and validity of our approach. Finally we identify some open research issues.
Advances in the approach to novel drug clinical development for breast cancer (2014)

It is important not to forget that the development of BC therapeutics is a 'moving target', as its biology evolves in time under the pressure of ongoing treatments. There are currently a finite number of resources available for the development of new therapeutics, which means that resources need to be carefully allocated. There is also a need to prioritize clinical trials that can reduce the number of patients who are candidates for expensive treatments.

Increased regimen durability in the era of once-daily fixed-dose combination antiretroviral therapy (2008)

Durability of contemporary once-daily fixed-dose antiretroviral regimens has significantly eclipsed the duration of earlier antiretroviral drug options. Our results indicate this is due to both more convenient dosing and improved tolerability of modern antiretroviral regimens.

Altering an Artificial Gagpolnef Polyprotein and Mode of ENV Co-Administration Affects the Immunogenicity of a Clade C HIV DNA Vaccine (2012)

HIV-1 candidate vaccines expressing an artificial polyprotein comprising Gag, Pol and Nef (GPN) and a secreted envelope protein (Env) were shown in recent Phase I/II clinical trials to induce high levels of polyfunctional T cell responses; however, Env-specific responses clearly exceeded those against Gag. Here, we assess the impact of the GPN immunogen design and variations in the formulation and vaccination regimen of a combined GPN/Env DNA vaccine on the T cell responses against the various HIV proteins. Subtle modifications were introduced into the GPN gene to increase Gag expression, modify the expression ratio of Gag to PolNef and support budding of virus-like particles. I.m. administration of the various DNA constructs into BALB/c mice resulted in an up to 10-fold increase in Gag- and Pol-specific IFNγ(+) CD8(+) T cells compared to GPN. Co-administering Env with Gag or GPN derivatives largely abrogated Gag-specific responses. Alterations in the molar ratio of the DNA vaccines and spatially or temporally separated administration induced more balanced T cell responses. Whereas forced co-expression of Gag and Env from one plasmid induced predominantly Env-specific T cells responses, deletion of the only H-2(d) T cell epitope in Env allowed increased levels of Gag-specific T cells, suggesting competition at an epitope level. Our data demonstrate that the biochemical properties of an artificial polyprotein clearly influence the levels of antigen-specific T cells, and variations in formulation and schedule can overcome competition for the induction of these responses. These results are guiding the design of ongoing pre-clinical and clinical trials.

Investigation of a Tandem Tilt-wing VTOL Aircraft in the NASA Langley 12-Foot Low-Speed Tunnel (2020)

The emerging Urban Air Mobility market imposes new design requirements on aircraft, including the ability to have vertical take-off and landing (VTOL) capabilities with the ability to transition into fast and efficient forward flight. Industry has proposed many different vehicle configurations, which have many different challenges. A primary challenge facing many of these concepts is flight through the transition corridor from vertical to horizontal flight and back. In an effort to better understand and help improve vehicle safety in the complex transition corridors, NASA Langley Research Center has proposed to characterize the transition corridor with wind tunnel and flight tests for a variety of unmanned aircraft system sized VTOL configurations. The first vehicle of this series is the Langley Aerodrome 8 (LA-8). LA-8 is a high-risk/high-reward tandem tilt-wing vehicle with distributed electric propulsion and a partially deflected slipstream aircraft. The LA-8 vehicle has gone through a preliminary wind tunnel test in NASA Langley's 12-Foot Low-Speed Wind Tunnel. The results of the aerodynamic data collected, including the longitudinal, lateral, and directional force and moment aerodynamic coefficients, from these tests during different phases of flight are presented.
fJ/bit photonic platform based on photonic crystals (2011)

Recently, photonic crystals have enabled a variety of ultrasmall photonic devices with extremely small energy consumption of ~fJ/bit level, suggesting that we can integrate a vast number of nanophotonic devices in a single chip. This technology may give us a way to introduce high-speed integrated nanophotonics in an information chip, which will be crucial in future ICT.
Bidirectional Joint Attention Mechanism for Target Tracking Algorithm (2022)

In this paper, we propose a target tracking algorithm SiamMT based on Siamese network architecture. The attention mechanism is introduced to solve the problem of semantic information loss caused by the classical traditional Siamese network architecture. Aiming at the problem that the target feature is not prominent and comprehensive, a bidirectional feature enhancement network model is proposed. The local and global attention mechanisms of MobileNet and Transformer are used to enhance and update bi-directional features, and then the attention mechanism and classification regression network are combined to form a fusion prediction network. This fusion mechanism effectively integrates local and global features, and breaks the limitations of the search domain method by making full use of spatial information and motion information. In order to solve the problem of complexity and inefficiency of tracking network, lightweight network MobileNet is introduced as an enhanced network with local features. Finally, the experiments on OTBIOO and LaSOT long-term benchmark show that the tracker in this paper has higher accuracy and success than other advanced trackers.
Colorimetric Enantiodiscrimination of α-Amino Acids in Protic Media (2005)

A new method is described for the determination of optical purity of alpha-amino acid samples in protic media. No derivatization of the analyte or multistep synthesis is required, and high accuracy is obtained from the colorimetric output. Chiral discrimination is achieved through the use of an optically pure trans-1,2-diaminocyclohexane-derived Cu(II)-containing host that differentiates amino acid enantiomers by a factor of about 2. Enantioselective signaling arises from the implementation of an indicator displacement assay based on competitive Cu(II) coordination involving the chiral Cu(II)-containing host, the amino acid guest, and a metal ion indicator. The molecular structure of the host/guest complex was determined by X-ray analysis and exhibits chelation of the Cu(II) center by the amino acid to provide substrate organization.

Design and fabrication of wide-angle TE-TM mode splitter in lithium niobate (2000)

A novel wide-angle TE-TM mode splitter in a Z-cut lithium niobate is presented. A straight random polarization nickel-indiffused waveguide and a proton-exchanged waveguide bend with substrate prism on the bend corner were combined to form an asymmetric wide-angle Y-branch. The waveguide bend with substrate prism bends the TM wave to the proton-exchanged waveguide with large angle. Hence, the TE wave is left in the straight NI waveguide. The experimental results show that the splitting ratios are 26 dB for the TE mode and 28 dB for the TM mode even at a splitting angle of 7.

The Inelastic Neutron Scattering Spectrum of H3B:NH3 and the Reproduction of Its Solid-State Features by Periodic DFT (2004)

The inelastic neutron scattering (INS) and periodic density functional theory (DFT) vibrational spectra of H3B:NH3 are reported to 1600 cm-1. The H3B:NH3 structural and INS features, specifically the reduced solid-state B:N dative bond length and the altered B:N stretching frequency, are reproduced by the periodic DFT calculations, placing the B:N stretching mode at 800 cm-1, in excellent agreement with experiment relative to previous nonperiodic theoretical treatments of this molecule.
Imaging of Tendons (2009)

Both magnetic resonance imaging (MRI) and sonography are well suited to tendon imaging. A normal tendon on MRI demonstrates low signal intensity and on sonography, an echogenic fibrillar pattern. MRI is considered the imaging gold standard, providing an anatomic overview and excellent soft tissue contrast. Sonography is a more rapidly performed examination; it has greater resolution than that of MRI; it allows dynamic evaluation of tendons and muscles; and it can guide percutaneous therapeutic procedures. Moreover, the advent of sonographic extended-field-of-view imaging allows the demonstration of the entire length of a tendon, matching MRI's ability to display a large anatomic region. Sonography should best be considered a focused examination, concentrating on the area of pain and clinical suspicion of pathology, whereas MRI can provide a global assessment of the region of concern. Both modalities demonstrate high accuracy for abnormalities of various tendons. This article reviews normal tendon anatomy and its imaging appearance, as well as the imaging appearances of tendon degeneration and tear.
