John C. Pew House (1938)

General view, from dock looking north, depicting house in landscape; The Pew house is one of Wright's few Usonian houses with a second floor. It takes advantage of its Lake Mendota shore site by having just one side anchored to the ground, the other end is supported by a limestone pier as the house passes over a ravine. A row of doors allows the balcony to function as an extension of the living room. Seen from the lake, the house appears to rise up the slope; it appears much larger than its 1,300 square feet from there. From the street, we can only see the square mass of the second floor bedrooms and the carport. Wright wisely did not have the house face the lake directly, but rather angeled it about 30 degrees. This allows the homeowners to have two separate views of the lake from two sides of the house, rather than just from the front. Source: http://www.dgunning.org/architecture/Wisc/pew.htm
Compact Tunable Balanced Bandpass Filter With Constant Bandwidth Based on Magnetically Coupled Resonators (2019)

In this letter, a compact high-selectivity and common-mode (CM) suppression tunable balanced microstrip bandpass filter (BPF) with constant bandwidth is designed by adopting the magnetically coupled resonators with stepimpedance parallel coupling feedline (SIPCF) structure. The desired coupling coefficient K <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sub> and external quality factor Q <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">e</sub> can be obtained by the mixed coupling between the two resonators and SIPCF structure, respectively. Two differential-mode (DM) transmission zeros (TZs) near the lower and upper passband edges are created by the mixed coupling and source- load coupling, respectively. Furthermore, intrinsic high CM suppression in the DM tunable operating passband can be maintained because of the magnetically coupled resonator structure. Finally, a compact tunable balanced BPF prototype with constant fractional bandwidth of 6.5% is implemented and fabricated. The measured results agree well with the simulated ones.
Reference-Based Clock Distribution Architectures (2006)

This paper examines the use of clock distribution architectures employing a reference-based skew compensation technique. For each clock domain, a bi-directional clock line is daisy-chained using specially designed switches at each tap in the distribution. Daisy-chaining the clock decreases the clock load by eliminating the redundant paths used to equalize delays in traditional H-tree distributions. Clock skew is accounted for by actively synchronizing each local clock to a position directly between forward and reverse-moving reference clocks. This reference-based clocking strategy achieves a set of skew-tolerant clocks at each tap in a daisy-chain. The design provides simple-to-layout and scalable multipoint skew compensation useful for large designs. The implementation of a reference-based clocking chain is outlined, followed by the description of single clock and multi-clock architectures using this design strategy.
Electron microscopy of endothelial cell-biopolymer interaction. (1990)

Vascular endothelial cells form a natural antithrombogenic lining on all blood vessels. Replacement or bypass of small diameter blood vessels with artificial polymeric grafts has not been clinically acceptable due to the thrombogenic nature of polymeric material. One approach to improving the patency of vascular prosthetic devices has been the establishment of endothelial monolayers on the blood flow surface using the technique known as seeding. Scanning electron microscopy has been a major tool in evaluating the interaction of endothelial cells with polymeric surfaces resulting in a basic understanding of forces and structures regulating endothelium-polymer interactions. In-vitro and in-vivo studies have established the feasibility of using endothelial cell seeding technology in human clinical trials. This tutorial describes the development of endothelial cell seeding technology and illustrates how scanning electron microscopic evaluations have furthered our understanding of endothelial cell-polymer interactions.
Hydroxide Ion Diffusion in Anion-Exchange Membranes at Low Hydration: Insights from Ab Initio Molecular Dynamics (2019)

Operation of anion-exchange membrane (AEM) fuel cells (AEMFCs) results in gradients in the cell that can lead to low-hydration conditions within the cell. It is therefore important to investigate hydroxide ion diffusion in AEMs with low water-to-cation ratios (λ ≤ 4, λ≡nH2O/ncation). In this work, ab initio molecular dynamics simulations are presented to explore hydroxide ion solvation complexes and diffusion mechanisms in model AEMs at low hydration. By changing the cation spacing within the AEM and the degree of hydration, six different idealized AEM models are created in which the water distribution is not uniform. It is shown that distinct water distributions impart unique OH– diffusion mechanisms that fall into three regimes. The observed mechanisms, nondiffusive, vehicular, and a mixture of structural and vehicular diffusion, depend on the presence or absence of a second solvation shell of the hydroxide ion and on the local water structure. The results suggest that the water distribution is a better descriptor than the value of λ for classifying AEMs under low-hydration conditions. These results enable us to posit idealized mechanisms for the three diffusion regimes and to define requirements for promoting OH– conductivity in high-performance AEMFC devices operating under low-hydration conditions.
Robust relational layout synthesis from examples for Android (2018)

We present a novel approach for synthesizing robust relational layouts from examples. Given an application design consisting of a set of views and their location on the screen, we synthesize a relational layout that when rendered, places the components at that same location. We present an end-to-end system, called InferUI, that addresses the above challenge in the context of Android. The system is based on the following technical contributions: (i) a formalization of the latest and most efficient ConstraintLayout class, capturing a rich set of relational constraints, (ii) a set of robustness properties designed to prevent common layout generalization errors, (iii) a synthesis algorithm that produces relational layouts that generalize across multiple screen sizes and resolutions, and (iv) a probabilistic model of constraints that guides the synthesizer towards layouts preferred by developers. Our evaluation shows that InferUI is practically effective: it successfully synthesizes real world complex layouts obtained from top 500 GitHub and top 500 Google Play Store applications, succeeds in 100% of the cases when synthesizing layouts for a single device, and correctly generalizes 92% of the views across multiple devices, all without requiring additional specifications.
Altered networks in bothersome tinnitus: a functional connectivity study (2012)

These results imply that in bothersome tinnitus there is dissociation between activity in auditory cortex and visual, attention and control networks. The reciprocal negative correlations in connectivity between these networks might be maladaptive or reflect adaptations to reduce phantom noise salience and conflict with attention to non-auditory tasks.
Mechanisms in the suppression of tumor rejection produced in mice by repeated UV irradiation. (1984)

Mice exposed repeatedly to UVB (280 to 320 nm) radiation are unable to reject highly antigenic UVB-induced skin cancers, and their lymphoid organs contain T lymphocytes that transfer this inability to nonimmune recipients. We show that the phenotype of the cells capable of transferring suppression of tumor rejection is Lyt-1+2-,Ia-. Removal of the suppressive activity of spleen cells from UVB-irradiated mice through the use of monoclonal anti-Lyt-1 antibodies resulted in a population of cells capable of mediating tumor rejection when injected into lethally x-irradiated recipients. This finding demonstrates that the inability of UVB-irradiated mice to reject skin cancers induced by UVB radiation is not due to clonal deletion, e.g., the absence of lymphocytes that are capable of recognizing and responding to antigens on these tumors, but instead is likely to depend solely on the activity of suppressor lymphocytes. The phenotype of antigen-specific suppressor lymphocytes induced by painting oxazalone on the unirradiated skin of mice exposed once to UVB radiation was Lyt-1+2-, also a finding consistent with the hypothesis that the two forms of UVB-induced immunosuppression occur by means of the same mechanism. The phenotype of suppressor cells induced in mice treated once with 8-methoxypsoralen plus UVA (320 to 400 nm) radiation, followed by painting unexposed skin with oxazalone, was Lyt-1+2+, suggesting that this treatment may activate a different suppressor pathway.
The Laplacian weighted minimum norm estimate of three dimensional equivalent charge distribution in the brain (2002)

A three dimensional equivalent charge distribution is estimated from scalp EEGs with the Laplacian weighted minimum norm solution. Computer simulations have been conducted to test the feasibility of the proposed approach. A three-shell concentric head volume conductor model was used in the present simulation study. The algorithm was tested using two kinds of source configurations: 4-dipoles and 4-charges. In both cases, the present equivalent charge distribution can provide a 3D equivalent source image of the assumed sources.
Blood Levels of Brain-Derived Neurotrophic Factor Correlate with Several Psychopathological Symptoms in Anorexia Nervosa Patients (2007)

Our data suggest that BDNF levels could be involved in the severity of the disease through the modulation of psychopathological traits that are associated with the ED phenotype.
Clinical results of hydrogel lens implantation (1986)

Polymethylmethacrylate has proven to be a useful intraocular lens (IOL) implant material and remains the most widely used material for the fabrication of IOLs. Complications, however, from IOL implantation still occur. A hydrogel lens has been designed for posterior chamber placement. A clinical study from August 1983 to June 1985 was undertaken to determine the safety and efficacy of this new lens manufactured from 38% poly HEMA. The noninflammatory postoperative complications were limited to lens decentration and opacification of the lens capsule. Three cases of posterior capsule opacification required YAG laser capsulotomy. Laser capsulotomy is feasible and the lens appeared to be more resistant to damage from the YAG laser than polymethylmethacrylate lenses. In general, the material appeared to be well tolerated and there have been no cases of persistent iritis or clinically detectable cystoid macular edema. If the visual acuity outcome by age decade for all patients irrespective of follow-up time is considered, 92% of patients achieved 20/40 or better corrected visual acuity.
Anionic lanthanide phenoxide complexes as novel single‐component initiators for the polymerization of ε‐caprolactone and trimethylene carbonate (2007)

Abstract The anionic lanthanide‐sodium‐2,6‐di‐ tert ‐butyl‐phenoxide complexes [Ln(OAr) 4 ][Na(DME) 3 ]·DME (Ln = Nd 1 (neodymium), Sm 2 (samarium), or Gd 3 (gadolium); DME = dimethoxyethane) were synthesized by the reaction of anhydrous LnCl 3 with 4 equiv of sodium‐2,6‐di‐ tert ‐butyl‐phenoxide NaOAr in high yields and structurally characterized. These complexes showed high catalytic activity in the ring‐opening polymerizations of ϵ‐caprolactone (ϵ‐CL) and trimethylene carbonate (TMC). The catalytic activity profoundly depended on the lanthanide metals. The active order of Gd < Sm < Nd for the polymerization of ϵ‐CL and TMC was observed. The polymers obtained with these initiators all showed a unimodal molecular weight distribution, indicating that the [Ln(OAr) 4 ][Na(DME) 3 ]·DME anionic complexes could be used as single‐component initiators. The anionic complex was more efficient than the corresponding neutral complex, Ln(OAr) 3 (THF) 2 . © 2007 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 45: 1210–1218, 2007
Effects of CI-930, a novel phosphodiesterase III inhibitor, on platelet aggregation and arachidonic acid metabolism. (1990)

In the platelet-rich plasma of rabbits, 4,5-dihydro-6-[4-(1H-imidazol-1-yl)phenyl]-5-methyl-3(2H)-pyridazinone (CI-930) inhibited platelet aggregation triggered by AA, U-46619, ADP, collagen and PAF, with the IC50 values of 0.91, 0.73, 2.12, 2.35 and 7.15 mumols/L, respectively. The inhibitory effect of CI-930 on AA-induced aggregation was potentiated by PGE1, an adenylate cyclase activator, and antagonized by SQ-22536, an adenylate cyclase inhibitor. The contents of cAMP in washed rabbit platelets were increased by CI-930 5-50 mumols/L. In the concentration range of 0.5-500 mumols/L, CI-930 reduced the synthesis of TXB2 by either washed rat or rabbit platelets or rat pleural neutrophils. At the same time, CI-930 induced a dose-dependent increase of PGE2, PGF2a, and PGD2 biosynthesis by rat platelets and had no significant influence on the formation of 6-keto-PGF1a by the neutrophils. It is showed that CI-930 is an anti-platelet agent with a wide-spectrum activity and its anti-aggregating action may be exerted by dual mechanisms, both increasing cAMP contents and selectively inhibiting TXA2 synthesis in platelets.
Mutational Analysis of Amino Acid Positions Crucial for IgE-Binding Epitopes of the Major Apple <i>(Malus domestica)</i> Allergen, Mal d 1 (2005)

Our findings suggest that it is possible to modulate the IgE-binding properties of allergens by single amino acid substitutions at crucial positions which might be useful for future immunotherapy of birch-pollen-associated food allergies which are not ameliorated by birch pollen immunotherapy.
A Look-Up-Based Universal Real-Time Transformer for Image Coding (1987)

A universal transformer for two-dimensional separable linear transforms in image coding is proposed. It is not restricted to fast transforms, and switching between transforms only requires writing the appropriate constants into an internal RAM. Look-up tables are used to reduce computational complexity. The linear transform properties are exploited to reduce the memory requirements by decomposing the input vector into smaller arrays and into bit planes. The input is pipelined into parallel data paths. An implementation example on a single gate array with existing technology achieves real-time transformation of 8 × 8 blocks, with area requirements of around 38K gates.

Micromeres are required for normal vegetal plate specification in sea urchin embryos (1995)

Vegetal plate specification was assessed in S. purpuratus embryos after micromere deletions at the 4th, 5th and 6th cleavages, by assaying expression of the early vegetal plate marker Endo 16, using whole-mount in situ hybridization. After 4th cleavage micromere deletions, the embryos typically displayed weak Endo16 expression in relatively few cells of the lineages that normally constitute the vegetal plate, while after 5th and 6th cleavage micromere deletions the embryos exhibited strong Endo16 expression in larger fractions of cells belonging to those lineages. When all four micromeres were deleted, the embryos were severely delayed in initiating gastrulation and sometimes failed to complete gastrulation. However, if only one micromere was allowed to remain in situ throughout development, the embryos exhibited strong Endo16 expression and gastrulation occurred normally, on schedule with controls. Additional measurements showed that these microsurgical manipulations do not alter cleavage rates or generally disrupt embryo organization. These results constitute direct evidence that the micromeres provide signals required by the macromere lineages for initiation of vegetal plate specification. The specification of the vegetal plate is completed in a normal manner only if micromere signaling is allowed to continue at least to the 6th cleavage stage.
Multi-bandgap high efficiency converter (RAINBOW) (2002)

Many proposals have been made to increase solar array efficiency by using two or more cells with appropriately spaced bandgaps to span a greater portion of the incident spectrum. One such technique is to split the solar spectrum and focus each portion on a different cell bandgap. Each bandgap is selected to best match the input spectral portion and thus obtain maximum efficiency. This paper reports on the reexamination of the spectrally split, individually matched cell approach using modern-day optics and lightweight structures. The RAINBOW multi-bandgap system represents a unique combination of solar cells, concentrators and beam splitters. The use of separate cells offers the widest possible scope of material choices. Many different component combinations are possible. The relatively low temperature operation, due to reduced thermal input per cell, adds to the performance increase. Finally, RAINBOW is a flexible system which can readily expand as new high efficiency components are developed. Based to a large extent on data for real cells and optical components, RAINBOW is expected to convert over 40% of incident solar energy to electricity at the system level. This conclusion is based on preliminary analyses of cell and optics performances.
Detection of Information and GSR Habituation: An Attempt to Derive Detection Efficiency From Two Habituation Curves (1975)

ABSTRACT The study attempts to describe the detection of information paradigm, based on differential GSR reactivity in terms of basic habituation processes. Two GSR habituation curves, for relevant and neutral stimuli, were generated rated on a sample of 83 Ss. Relevant and neutral stimuli exhibited similar habituation curves, From these two habituation curves it was possible to predict in a meaningful fashion the characteristics of standard information detection experiments using a notion of dichotomization . This notion refers to separate habituation processes for the relevant and neutral stimulus categories . The predictions were tested on an additional sample of 102 Ss. It was found that without additional assumptions it was possible to predict, at least the order, of the efficiencies of detection in various information detection tasks. In light of the present results, consideration was given to Sokolov's concept of “signal value.”
SMILE: A Data Sharing Platform for Mobile Apps in the Cloud (2014)

We identify an opportunity to share data among mobile apps hosted in the cloud, thus helping users improve their mobile experience, while resulting in cost savings for the cloud provider. In this work, we propose a platform for sharing data among mobile apps hosted in the cloud. A “sharing” is specified by a triple consisting of: (a) a set of data sources to be shared, (b) a set of specified transformations on the shared data, and (c) a staleness (freshness) requirement on the shared data. The platform addresses the following two main challenges: What sharings to admit into the system under a set of specified constraints, how to implement a sharing at a low cost while maintaining the desired level of staleness. We show that reductions in costs are achievable by exploiting the commonalities between the different sharings in the platform. Experimental evaluation is performed with a cloud platform containing 25 sharings among mobile apps with realistic datasets containing user, social, location and checkin data. Our platform is able to maintain the sharings with very few violations, even under a very high update rate. Our results show that our method results in a cost savings of over 35% for the cloud provider, while enabling an improved mobile experience for users.
On views and XML (1999)

XML data for us refers to data in XML and not to the precursor of DCD, a typing language for XML, that was called XML data. we prefer to use the term XML data instead of XML document to stress that our prime concern is in data exchange and not in document management.
Incentives for Efficient Inventory Management: The Role of Historical Cost (2005)

This paper examines inventory management from an incentive perspective. We show that when a manager has private information about future attainable revenues, the residual income performance measure based on historical cost can achieve optimal (second-best) incentives with regard to managerial effort as well as production and sales decisions. The LIFO (last-in–first-out) inventory flow rule is shown to be preferable to the FIFO (first-in–first-out) rule for the purpose of aligning incentives. Our analysis also finds support for the lower-of-cost-or-market inventory-valuation rule in situations where the manager receives new information after the initial contracting stage.
Antibody immunosuppressive therapy in solid-organ transplant (2010)

Currently, a wide variety of both polyclonal and monoclonal antibodies are being routinely utilized to prevent and treat solid organ rejection. More commonly, these agents are also administered in order to delay introduction of calcineurin inhibitors, especially in patients with already compromised renal function. While these antibody therapies dramatically reduced the incidence of acute rejection episodes and improved both short and long-term graft survival, they are also associated with an increased incidence of opportunistic infections and neoplastic complications. Therefore, effective patient management must necessarily balance these risks against the potential benefits of the therapy.
Vaccine‐Like Immunity against Malaria by Repeated Causal‐Prophylactic Treatment of Liver‐Stage<i>Plasmodium</i>Parasites (2009)

Liver-stage development of Plasmodium parasites represents a dramatic expansion phase for the malarial parasite between vector transmission and onset of the pathogenic blood-stage cycle. Here, we report that repeated causal-prophylactic primaquine treatment of liver-stage Plasmodium parasites in rodents elicits vaccine-like protective immunity against sporozoite-induced malaria. This regimen differs fundamentally from those involving radiation- or genetically attenuated parasites, in which long-lasting immune responses are dependent on persistence of metabolically active parasites. Pharmacological inhibition of liver-stage parasites in the rodent malaria model offers a potential fast track toward development of a vaccine that targets parasites in preerythrocytic stages.
