A Cross-Cultural Comparison of American, Palestinian, and SwedishPerception of Charismatic Speech: Powerpoint Poster (2008)

Perception of charisma, the ability to inﬂuence others by virtue of one’s personal qualities, appears to be inﬂuenced to some extent by cultural factors. We compare results of ﬁve studies of charisma speech in which American, Palestinian, and Swedish subjects rated Standard American English political speech and Americans and Palestinians rated Palestinian Arabic speech. We identify acoustic-prosodic and lexical features correlated with charisma ratings of both languages for native and non-native speakers and ﬁnd that 1) some acoustic-prosodic features correlated with charisma ratings appear similar across all ﬁve experiments; 2) other acoustic-prosodic and lexical features correlated with charisma appear speciﬁc to the language rated, whatever the native language of the rater; and 3) still other acoustic-prosodic cues appear speciﬁc to both rater native language and to language rated. We also ﬁnd that, while the absolute ratings non-native raters assign tend to be lower than those of native speakers, the ratings themselves are strongly correlated.
A fission fragment reactor concept for nuclear thermal propulsion (1992)

The Space Exploration Initiative requires the development of nuclear thermal and nuclear electric technologies for space propulsion for future Luna and Mars missions. Sandia National Laboratories has proposed a new nuclear thermal propulsion concept that uses fission fragments to directly heat the propellant up to 1000 K or higher above the material temperatures. The concept offers significant advantages over traditional solid‐core nuclear rocket concepts because of higher propellent exit temperatures, while at the same time providing for more reliable operation due to lower structure temperatures and lower power densities. The reactor can be operated in either a steady‐state or pulsed mode. The steady‐state mode provides a high thrust and relatively high specific impulse, as compared to other nuclear thermal concepts. The pulsed mode requires an auxillary radiator for cooling, but has the possibility of achieving very high specific impulses and thrust scaleable to the radiator size. The propellant temperatures are limited only by thermal radiation and transient heat conduction back to the substrate walls.
Data mining for proteins characteristic of clades (2006)

A synapomorphy is a phylogenetic character that provides evidence of shared descent. Ideally a synapomorphy is ubiquitous within the clade of related organisms and nonexistent outside the clade, implying that it arose after divergence from other extant species and before the last common ancestor of the clade. With the recent proliferation of genetic sequence data, molecular synapomorphies have assumed great importance, yet there is no convenient means to search for them over entire genomes. We have developed a new program called Conserv, which can rapidly assemble orthologous sequences and rank them by various metrics, such as degree of conservation or divergence from out-group orthologs. We have used Conserv to conduct a largescale search for molecular synapomorphies for bacterial clades. The search discovered sequences unique to clades, such as Actinobacteria, Firmicutes and gamma-Proteobacteria, and shed light on several open questions, such as whether Symbiobacterium thermophilum belongs with Actinobacteria or Firmicutes. We conclude that Conserv can quickly marshall evidence relevant to evolutionary questions that would be much harder to assemble with other tools.

Preparation of high efficiency visible light activated Pt/CdS photocatalyst for solar hydrogen production (2007)

Production of hydrogen by water splitting using solar energy is one of the long sought goals of hydrogen economy. Approximately 33% of solar radiation is emitted as high energy photons while the remaining 67% consists of primarily thermal energy. Utilization of both thermal and photonic energies within the solar spectrum is essential for achieving water splitting at high efficiency. At FSEC, we have developed a solar-thermochemical water splitting cycle for the production of hydrogen. In this cycle, the photonic portion of solar irradiance is diverted and used to drive the hydrogen production step, while solar thermal portion drives the oxygen generation step of the cycle. The photocatalytic hydrogen production step of the cycle employs aqueous ammonium sulfite solution that is oxidized to ammonium sulfate in the presence of nanosized photocatalysts. We have developed a technique for the preparation of polymer encapsulated nanosize photocatalysts that show high activity toward oxidation of ammonium sulfite aqueous solution. The use of nano-scale and defect free photocatalysts hinder the recombination of photo-generated electron-hole pairs, thereby increasing solar to hydrogen energy conversion efficiency.
Bovine Reproductive Health in the 21st Century (1992)

Predicting the future is a skill that is not taught in most veterinary curricula, and not practiced by most learned veterinarians. It is an endeavor fraught with hazard, the greatest of which being that a small but wicked minority of those who hear one's predictions will remember them at an importune moment in the future.

Tic-Tac-Textiles: A waiting game (2010)

In light of the imminent arrival of ambient intelligence and smart textiles, the design of computational and textile things are rapidly converging. Substantial attention is directed towards the new technical possibilities of these new materials, but less effort seems to be put into the challenging task of re-thinking the use of textiles and computational technology as design materials on the basis of the complex mixture of traditions, perspectives, concepts and methods that result from such convergence. These challenges and opportunities inspired the IT+Textiles design research program. Trying to dissolve the distinction between technologies and design materials, we have combined textile and interaction design, textile and electrical engineering, philosophy and the behavioural sciences to find new approaches to issues of use and context, form and aesthetics, practice and theory. In this book, we describe the collection of materials, examples, methods and concepts we have developed in our investigation of this emerging design space.

Anisotropic regularization of ultrasound pulse-echo tomography for reconstruction of speed-of-sound and tissue heterogeneity through abdominal layers (2020)

Regularization has a critical impact on the performance of pulse-echo computed-tomography and is a key component of the speed-of-sound (SoS) reconstruction pipeline. We investigate SoS reconstruction accuracy through heterogeneous abdominal models. We propose anisotropic regularization approaches, which integrate available gradient information for both Tikhonov (L2) and Total Variation (L1) regularizers. Our results show that different target clinical applications, for instance, quantification of focal lesions or diffuse disease may benefit from different regularization approaches. Reconstruction of SoS distributions through abdominal layers was feasible in limited-angle ray tracing simulations, with Pearson coefficient r = 0.909 for estimation of SoS baseline (mean) and r = 0.66 for estimation of SoS heteroaeneity (std. deviation).
Towards scalable networks of solid-state quantum memories in a photonic integrated circuit (Presentation Recording) (2015)

A central goal of quantum information science is the entanglement of multiple quantum memories that can be individually controlled. Here, we discuss progress towards photonic integrated circuits designed to enable efficient optical interactions between multiple spin qubits in nitrogen vacancy (NV) centers in diamond. We describe NV-nanocavity systems in the strong Purcell regime with optical quality factors approaching 10,000 and electron spin coherence times exceeding 200 &mu;s; implantation of NVs with nanometer-scale apertures, including into cavity field maxima; hybrid on-chip networks for integration of multiple functional NV-cavity systems; and scalable integration of superconducting nanowire single photon detectors on-chip.
Cannabinoids May Have a Neuroprotective Effect in MS (2004)

Multiple sclerosis (MS) is caused by CNS inflammation. This inflammation is generally believed to result from an autoimmune process that targets brain
BIOMARKERS, SELF-ANTIGENS & THE IMMUNOLOGICAL HOMUNCULUS (2012)

The notion of the immunological homunculus arose from the observations that the healthy adaptive immune system is inclined to respond (T cell reactivity and auto antibodies) to particular sets of body molecules (self-antigens) and that autoimmune diseases are characterized by sets of autoimmune reactivity to some of the very same self-antigens recognized by healthy subjects - with an obvious difference in outcome. I termed this natural autoimmune structuring of the immune system, the immunological homunculus - the immune system’s representation of the body. What might be the selective advantage of an immune system expressing patterns of built-in autoimmunity to particular sets of self-molecules? To better characterize the homunculus, we have used informatic tools to study patterns of antibodies to many hundreds of self-molecules arrayed on glass slides - an antigen chip of our design. Results using the antigen chip suggest that the particular self-reactivities comprising the homunculus could serve as a set of biomarkers that help the immune system initiate and regulate the inflammatory processes that maintain the body.
Alterations in Plasma Oxidative Stress Markers After Laparoscopic Operations of the Upper and Lower Abdomen (2005)

The patient's position during laparoscopic surgery can have a clinically relevant effect on lower limb and splanchnic circulation; this factor has not yet been investigated with respect to oxidative stress markers. In order to assess this effect, a prospective clinical trial was designed wherein 2 groups of patients were studied. In group A, 15 patients underwent upper abdominal nonhepatobiliary operations (13 modified Nissen fundoplications and 2 Taylor vagotomies) in the head-up position. In group B, 15 patients underwent lower abdominal operations (10 laparoscopic colectomies and 5 inguinal hernia repairs) in the head-down position. The pneumoperitoneum was maintained at 14 mm Hg in all cases. Plasma concentrations of thiobarbituric-acid reactive substances (TBARS), a marker of lipid peroxidation, plasma total antioxidant status (TAS), and serum uric acid concentrations were measured preoperatively, 5 minutes after deflation of the pneumoperitoneum, and 24 hours postoperatively. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) serum activities were measured preoperatively and 24 hours postoperatively. In group A, there was a significant increase in TBARS levels (p<0.005) immediately after deflation of the pneumoperitoneum and a significant decrease in TAS and uric acid levels (p<0.005) in the first postoperative day. There was also a significant postoperative elevation in both ALT and AST activities (p<0.001). In group B, no significant increase was found in postoperative TBARS or transaminase levels. TAS and uric acid levels decreased significantly in the first postoperative day (p<0.05) and (p<0.005, respectively). In conclusion, these results show that a combination of pneumoperitoneum and the head-up position causes significant increase in lipid peroxidation, decrease in plasma TAS, and increase in transaminases. The mechanism responsible for these events could be the low-flow ischemia-reperfusion syndrome induced by the pneumoperitoneum and aggravated by the head-up position.
Geometric methods for improving the upper bounds on the number of rational points on algebraic curves over finite fields (2001)

Currently, the best upper bounds on the number of rational points on an absolutely irreducible, smooth, projective algebraic curve of genus g defined over a finite field F_q come either from Serre's refinement of the Weil bound if the genus is small compared to q, or from Oesterle's optimization of the explicit formulae method if the genus is large. This paper presents three methods for improving these bounds. The arguments used are the indecomposability of the theta divisor of a curve, Galois descent, and Honda-Tate theory. Examples of improvements on the bounds include lowering them for a wide range of small genus when q=2^3, 2^5, 2^{13}, 3^3, 3^5, 5^3, 5^7, and when q=2^{2s}, s&gt;1. For large genera, isolated improvements are obtained for q=3,8,9.
Electrodeposition As an Approach for Fabricating High Performance Battery Electrodes (2016)

Conventionally, battery electrodes are prepared from physical mixtures of conductive additives, polymeric binders, and electroactive active material particles which are usually coated onto metal foil current collectors. The three passive components serve distinct functions, where the current collector provides structural support, the binder maintains physical adhesion throughout the composite, and the conductive additives establish an interconnected conduction network. Minimizing the mass of passive material in the electrode is desirable to maximize functional gravimetric capacity. To maximize energy density and rate capability, obtaining a continuous conductive pathway with open pores for fast ion transport is critical. Electrodeposition is presented here as a design strategy for lightweight, high performing, high energy density battery electrodes. Opportunity for removal or reduction of passive components will be discussed. Examples of direct deposition of electroactive particles onto a three-dimensional, lightweight, conductive substrate will be described, along with functional testing of the resulting composite electrodes for beyond lithium-ion batteries (i.e. magnesium-ion batteries and metal air batteries). Benefits of the electrodeposition based fabrication strategy, including quantitative control over active material loading, and opportunity to realize continuous electrical contact by design, will be highlighted.

Candid Interaction (2015)

The growth of mobile and wearable technologies has made it often difficult to understand what people in our surroundings are doing with their technology. In this paper, we introduce the concept of candid interaction: techniques for providing awareness about our mobile and wearable device usage to others in the vicinity. We motivate and ground this exploration through a survey on current attitudes toward device usage during interpersonal encounters. We then explore a design space for candid interaction through seven prototypes that leverage a wide range of technological enhancements, such as Augmented Reality, shape memory muscle wire, and wearable projection. Preliminary user feedback of our prototypes highlights the trade-offs between the benefits of sharing device activity and the need to protect user privacy.
Potential Clinical Uses of CDK Inhibitors: Lessons from Synthetic Lethality Screens (2015)

Developments in genetic and genomic technology have produced vast quantities of data that are gradually yielding new insights into fundamental cellular and molecular processes. In particular, they have revealed some differences between normal and transformed cells that could potentially be exploited to develop targeted, personalized cancer therapies with unprecedented efficiencies. This review summarizes recent findings from synthetic lethality (SL) screens against cyclin-dependent kinases (CDKs) that can be targeted with small molecule kinase inhibitors. SL screens can be used to identify cancers sensitive to CDK inhibitors. Several SL partners of specific CDKs have been identified, including MYC, K-Ras, VHL, PI3K, and PARP, all of which are discussed in the review. CDK inhibitors have been in clinical trials for nearly 20 years and it has become clear that effective therapy using these compounds will require careful selection of patients with respect to the specific molecular phenotype of their disease.
Equivalent circuit models for canonical chiral elements (2003)

An external load can be connected to a chiral clement in two ways; a parallel connection or a series connection. The parallel connection places the external load across the dipole-loop gap, putting the loop terminals, the dipole terminals and the load terminals in parallel. The other configuration breaks the connection between the dipole and loop sections at the center gap, reconnecting the loop, the load and the dipole in a series configuration. The terminal impedance and backscatter behavior of the chiral clement is different for each connection method. The objective of this paper is to develop useful equivalent circuit models for both series connected and parallel connected versions of canonical chiral elements.
Defective Production of Myeloid Dendritic Cells Results from Skewing of Chronic Myelogenous Leukemia Progenitors. (2004)

Abstract The robustness of the immunostimulatory response generated by dendritic cells (DCs) has positioned these cells as central and determining cellular mediators of T cell activation. Their production in sufficient number from hematopoietic precursors is crucial in order to drive immune responses. To determine the capacity of CML clonogenic cells to generate dendritic cells expressing endogenous CML-specific epitopes, we have evaluated the generation of DCs from CD34+ progenitor cells and CD14+ monocytes isolated from patients with CML (n=28). We found that the kinetics of production of DCs, in GM-CSF 800U/ml, TNF-a 50U/ml and IL-4 10U/ml, from CD34+ progenitors of CML patients were significantly delayed in comparison to healthy controls (p&amp;lt;0.05). Even after 20 day-cultures, DC numbers remained decreased (P&amp;lt;0.01). A proliferative defect of CML blasts cannot explain this finding since CD34+ cells divided normally according to total cell culture count and CFSE staining. Flow cytometry analysis of the few DCs produced from CML CD34+ cells showed the same phenotypic characteristics of expression of MHC (class I and II), costimulatory (CD80, CD86) and adhesion molecules (CD11a, CD11b and CD58), as DCs generated from control CD34+ cells, except for late downregulation of CD11a. Normal maturation of DCs from CML CD14+ cells and a sustained proportion of the bcr-abl+ DCs before and after DC expansion excluded a 9:22 translocation-induced differentiation defect. However, retarded down-modulation of the CD34 antigen at the surface of CML blasts, independently of IL-4 receptor synthesis, rather suggested decreased susceptibility of CML progenitors to IL-4 and GM-CSF-mediated DC growth conditions. Indeed, CML progenitors, plated in semi-solid media, showed an important skewing toward more mature progenitors (BFU-E and late CFU-GM) with a significant decrease in immature CFU-GM (&amp;gt; 500 cells) (CML = 29 vs normal = 95 colonies, P&amp;lt;0.001) and CFU-Mix (CML = 0.6 vs normal = 5.6 colonies, P=0.0006). Moreover, the number of DCs obtained after 10 and 15 day-cultures showed a strong correlation with the number of immature CFU-GM and CFU-Mix colonies (R=0.95). Thus, our study identifies a selective impairment in DC production from CD34+ progenitors of CML patients corresponding to a skewing of the progenitor cell compartment toward mature myeloid and/or erythroid progenitors. The lack of DCs derived from leukemia progenitors may explain the immunologic escape of CML clonogenic cells and provides clues to enhance their immune recognition.
Flight performance of micro-wings rotating in an alternating magnetic field (1999)

The flight mechanism that gains thrust by rotating magnetic wings in an alternating magnetic field is proposed. Through the analysis and the experiments with large-sized models whose wing length is from 3 mm to 8.6 mm, some hints for the design of micro-sized models whose wing length is around 1 mm were shown. That is, the wings should be flat, the angle of attack should be over 25 degrees, and the take-off frequency is estimated to be 600 Hz. We made micro-sized models using MEMS technology. The wings are made of electroplated nickel, and a thin glass rod is attached to the center as an axis of rotation. The glass rod is inserted into a small glass tube which works as an outer bearing. The 900 /spl mu/m long micro-wings succeed in flying up at a rotating frequency of 570 Hz. The thrust generated by the wings at 570 Hz can be regarded as the weight of the micro-wings.
Design of a phased array for the generation of adaptive radiation force along a path surrounding a breast lesion for dynamic ultrasound elastography imaging (2013)

This work demonstrates, with numerical simulations, the potential of an octagonal probe for the generation of radiation forces in a set of points following a path surrounding a breast lesion in the context of dynamic ultrasound elastography imaging. Because of the in-going wave adaptive focusing strategy, the proposed method is adapted to induce shear wave fronts to interact optimally with complex lesions. Transducer elements were based on 1-3 piezocomposite material. Three-dimensional simulations combining the finite element method and boundary element method with periodic boundary conditions in the elevation direction were used to predict acoustic wave radiation in a targeted region of interest. The coupling factor of the piezocomposite material and the radiated power of the transducer were optimized. The transducer's electrical impedance was targeted to 50 Ω. The probe was simulated by assembling the designed transducer elements to build an octagonal phased-array with 256 elements on each edge (for a total of 2048 elements). The central frequency is 4.54 MHz; simulated transducer elements are able to deliver enough power and can generate the radiation force with a relatively low level of voltage excitation. Using dynamic transmitter beamforming techniques, the radiation force along a path and resulting acoustic pattern in the breast were simulated assuming a linear isotropic medium. Magnitude and orientation of the acoustic intensity (radiation force) at any point of a generation path could be controlled for the case of an example representing a heterogeneous medium with an embedded soft mechanical inclusion.
