Using collar-worn sensors to forecast thermal strain in military working dogs (2016)

Military working dogs (MWDs) are at high risk of heat strain both during training and missions. Body heat in a MWD increases due to work, and the primary means for reducing this heat are resting and panting. Body-worn sensors can enable monitoring of work level and respiratory rate in real time. They can thereby provide real-time objective indicators of thermal strain in MWDs. In this paper a system is proposed for using collar-worn accelerometer, global positioning system (GPS), and audio recorder sensors to provide real-time estimates of work level and respiration (breathing and panting) rate. Automated methods are demonstrated for using a collar-worn accelerometer and GPS sensor to estimate work levels during multiple short-duration activities, and for estimating respiration rates from a collar-worn audio recorder. The potential utility of these estimates for forecasting and monitoring thermal strain is assessed based on performance in out of sample prediction of core temperature (Tc) statistics, which are obtained from ingestible sensors. Using cross-validation, regression models are trained from accelerometer- and GPS-based activity estimates to predict rate of change in Tc, obtaining a correlation of r=0.59 between actual and predicted Tc change rates. Regression models are also trained from audio-based respiration rate estimates during recovery to predict the Tc values immediately prior to recovery, obtaining a correlation of r=0.49 between actual and predicted Tc.
High Availability of the α7-Nicotinic Acetylcholine Receptor in Brains of Individuals with Mild Cognitive Impairment: A Pilot Study Using 18F-ASEM PET (2019)

Emerging evidence supports a hypothesized role for the 7-nicotinic acetylcholine receptor (7-nAChR) in the pathophysiology of Alzheimer's disease. 18 F-ASEM (3-(1,4-diazabicyclo[3.2.2]nonan-4-yl)-6-18 F-fluorodibenzo[b,d]thiophene 5,5-dioxide) is a radioligand for estimating the availability of 7-nAChR in the brain in vivo with PET. Methods: In this cross-sectional study, 14 patients with mild cognitive impairment (MCI), a prodromal stage to dementia, and 17 cognitively intact, elderly controls completed 18 F-ASEM PET. For each participant, binding in each region of interest was estimated using Logan graphical analysis with a metabolite-corrected arterial input function. Results: Higher 18 F-ASEM binding was observed in MCI patients than in controls across all regions, supporting higher availability of 7-nAChR in MCI. 18 F-ASEM binding was not associated with verbal memory in this small MCI sample. Conclusion: These data support use of 18 F-ASEM PET to examine further the relationship between 7-nAChR availability and MCI.
Learning, positioning, and tracking visual appearance (2002)

The problem of vision-based robot positioning and tracking is addressed. A general learning algorithm is presented for determining the mapping between robot position and object appearance. The robot is first moved through several displacements with respect to its desired position, and a large set of object images is acquired. This image set is compressed using principal component analysis to obtain a four-dimensional subspace. Variations in object images due to robot displacements are represented as a compact parametrized manifold in the subspace. While positioning or tracking, errors in end-effector coordinates are efficiently computed from a single brightness image using the parametric manifold representation. The learning component enables accurate visual control without any prior hand-eye calibration. Several experiments have been conducted to demonstrate the practical feasibility of the proposed positioning/tracking approach and its relevance to industrial applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
CW results of a 460 GHz second harmonic gyrotron oscillator - for sensitivity enhanced NMR (2006)

We report microsecond pulse and CW results of a gyrotron operating near 460 GHz and 230 GHz at the second electron cyclotron harmonic and fundamental, respectively. Peak power levels of up to 70 W at the fundamental and 3 W at the second harmonic have been obtained in operation at up to 13 kV and 150 mA. The gyrotron has been operated continuously to achieve 3 W CW at the second harmonic. The gyrotron was also demonstrated as a wideband continuous frequency tunable oscillator by magnetically exciting fundamental higher order longitudinal modes. The gyrotron oscillator can be used for dynamic nuclear polarization (DNP) studies in conjunction with a 700 MHz (/sup 1/H), 16.5 T nuclear magnetic resonance (NMR) spectrometer.

The crystal structure of the secreted aspartic proteinase 3 from Candida albicans and its complex with pepstatin A (2007)

The family of secreted aspartic proteinases (Sap) encoded by 10 SAP genes is an important virulence factor during Candida albicans (C. albicans) infections. Antagonists to Saps could be envisioned to help prevent or treat candidosis in immunocompromised patients. The knowledge of several Sap structures is crucial for inhibitor design; only the structure of Sap2 is known. We report the 1.9 and 2.2 A resolution X-ray crystal structures of Sap3 in a stable complex with pepstatin A and in the absence of an inhibitor, shedding further light on the enzyme inhibitor binding. Inhibitor binding causes active site closure by the movement of a flap segment. Comparison of the structures of Sap3 and Sap2 identifies elements responsible for the specificity of each isoenzyme.

Synthesis and Luminescence of Eu2+ Activated Yellow Oxynitride Phosphor (2013)

In this paper, we discuss synthesis and luminescence properties of a novel yellow phosphor composition, Ba 4 Si 9 (O,N) 16- d :Eu 2+ (YON). The powder x-ray diffraction pattern indicates formation of a new oxynitride phase with a minor secondary phase of BaSi 7 N 10 . To our knowledge, the composition and luminescence properties of this oxynitride material has not been reported earlier. YON crystallizes in monoclinic crystal system with unit cell parameters a=5.7598(1)Å, b=7.0499(1)Å, c=9.6315(1)Å, b = 107.362(1). The Eu 2+ activated material shows efficient yellow emission peaking around ~580nm under UV/blue excitation. The emission position can be tuned by Sr 2+ /Ca 2+ substitution in the Ba 2+ site. We also investigate the nature of their emission at different Eu 2+ concentration levels and at elevated temperatures. Warm white lamps built using phosphor blends with this new phosphor are capable of making high CRI, warm white lamps with high lumen equivalents (&gt;325 lm/W opt ).
Compact and scalable three-dimensional microelectromechanical system optical switches [Invited] (2007)

&lt;p&gt;&lt;a href="http://www.osa-jon.org/virtual_issue.cfm?vid=28"&gt;Feature Issue on Nanoscale Integrated Photonics for Optical Networks&lt;/a&gt;&lt;/p&gt;We review the performance and applications of compact (20cm&lt;sup&gt;3&lt;/sup&gt;) and large-scale (320×320) three-dimensional microelectromechanical system (3-D MEMS) based optical switches. The low loss (&lt;3dB for all 102,400 paths) and variable attenuation capable optical switch performs penalty-free for cascaded operation at 40Gbits/s. Scalability and performance of integrated wavelength-selective cross-connects based on 3-D MEMS with an unprecedented 12.8Tbit/s switching capacity for next-generation all-optical networks are also presented.
The Effect of Cathodic Arc Guiding Magnetic Field on the Growth of (Ti0.36Al0.64)N Coatings (2019)

We use a modified cathodic arc deposition technique, including an electromagnetic coil that introduces a magnetic field in the vicinity of the source, to study its influence on the growth of (Ti0.36Al0.64)N coatings. By increasing the strength of the magnetic field produced by the coil, the cathode arc spots are steered toward the edge of the cathode, and the electrons are guided to an annular anode surrounding the cathode. As a result, the plasma density between the cathode and substrate decreased, which was observed as a lateral spread of the plasma plume, and a reduction of the deposition rate. Optical emission spectroscopy shows reduced intensities of all recorded plasma species when the magnetic field is increased due to a lower number of collisions resulting in excitation. We note a charge-to-mass ratio decrease of 12% when the magnetic field is increased, which is likely caused by a reduced degree of gas phase ionization, mainly through a decrease in N2 ionization. (Ti0.36Al0.64)N coatings grown at different plasma densities show considerable variations in grain size and phase composition. Two growth modes were identified, resulting in coatings with (i) a fine-grained glassy cubic and wurtzite phase mixture when deposited with a weak magnetic field, and (ii) a coarse-grained columnar cubic phase with a strong magnetic field. The latter conditions result in lower energy flux to the coating’s growth front, which suppresses surface diffusion and favors the formation of c-(Ti,Al)N solid solutions over phase segregated c-TiN and w-AlN.
Visual analytics for team-based invasion sports with significant events and Markov reward process (2019)

In team-based invasion sports such as soccer and basketball, analytics is important for teams to understand their performance and for audiences to understand matches better. The present work focuses on performing visual analytics to evaluate the value of any kind of event occurring in a sports match with a continuous parameter space. Here, the continuous parameter space involves the time, location, score, and other parameters. Because the spatiotemporal data used in such analytics is a low-level representation and has a very large size, however, traditional analytics may need to discretize the continuous parameter space (e.g., subdivide the playing area) or use a local feature to limit the analysis to specific events (e.g., only shots). These approaches make evaluation impossible for any kind of event with a continuous parameter space. To solve this problem, we consider a whole match as a Markov chain of significant events, so that event values can be estimated with a continuous parameter space by solving the Markov chain with a machine learning model. The significant events are first extracted by considering the time-varying distribution of players to represent the whole match. Then, the extracted events are redefined as different states with the continuous parameter space and built as a Markov chain so that a Markov reward process can be applied. Finally, the Markov reward process is solved by a customized fitted-value iteration algorithm so that the event values with the continuous parameter space can be predicted by a regression model. As a result, the event values can be visually inspected over the whole playing field under arbitrary given conditions. Experimental results with real soccer data show the effectiveness of the proposed system.

Analysis of parallel hierarchical matching schedulers for input-queued switches under different traffic conditions (2004)

Input-queued packet switches are more scalable than output-queued ones. However, due to HOL blocking, their throughput is poor. The virtual output queueing (VOQ) switch architecture and several buffer schedulers have been proposed to overcome this problem. Among them, the class of iterative maximal matching algorithms, with the first example being parallel iterative matching (PIM), which uses random selection, and iSLIP that uses round-robin selection, and has become a de facto standard in switching research. iSLIP admit efficient practical implementations, and has several variants with different pointer updating strategies - like FIRM, DRRM and RDSRR - that improve performance. In previous work, we formulated a new scheduler, parallel hierarchical matching (PHM), which compare favorably to iSLIP-like algorithms. PHM can be considered a parallelization of previous high-performance sequential hierarchical matching algorithms, like 2DRR or WWFA. In this paper, we compare their delay performance for same decision response-time, determined from ASIC implementations, and for different traffic models.
Fourier spectrum of radially periodic images (1997)

Although the spectrum of radially periodic images is often expressed in terms of finite or infinite series of Bessel functions, such expressions do not clearly reveal the exact impulsive structure of the spectrum. An alternative Fourier decomposition of radially periodic images, in terms of circular cosine functions, is presented, and its significant advantages are shown. It is shown that the Fourier transform of the circular cosine function, which can be expressed in terms of a half-order derivative of the impulse ring δ(r-f), plays a fundamental role in the spectra of radially periodic functions. Just as any symmetric periodic function p(x) in the one-dimensional case can be represented by a sum of cosines with frequencies of f=1/T, 2/T, … [the Fourier series decomposition of p(x)], a radially periodic function in the two-dimensional case can be decomposed into a circular Fourier series, which is a sum of circular cosine functions with radial frequencies of f=1/T, 2/T, … . This result can also be formulated in terms of the spectral domain: Just as the Fourier transform of a one-dimensional periodic function consists of impulse pairs located at f=n/T (the Fourier transforms of the cosines in the sum), the Fourier spectrum of a radially periodic function in the two-dimensional case consists of half-order derivative impulse rings with radii f=n/T (which are the Fourier transforms of the circular cosines in the sum). The significance of these results is discussed, and it is briefly shown how they can be extended into dimensions other than two.
Advantages of percent weight loss as a method of reporting weight loss after Roux‐en‐Y gastric bypass (2013)

Of the metrics examined, %WL is the parameter describing WL after RYGB least influenced by pBMI. It thus improves comparison of WL outcomes across studies of patients undergoing surgery and facilitates the most sensitive identification of novel predictors of surgery-induced WL. We therefore is recommend that %WL be adopted more broadly in reporting weight loss after RYGB.
Unique Electronic Structure in a Porous Ga‐In Bimetallic Oxide Nano‐Photocatalyst with Atomically Thin Pore Walls (2016)

Abstract A facile synthetic route is presented that produces a porous Ga‐In bimetallic oxide nanophotocatalyst with atomically thin pore walls. The material has an unprecedented electronic structure arising from its ultrathin walls. The bottom of the conduction band and the top of the valence band of the material are distributed on two opposite surfaces separated with a small electrostatic potential difference. This not only shortens the distance by which the photogenerated charges travel from the sites where they are generated to the sites where they catalyze the reactions, but also facilitates charge separations in the material. The porous structure within the walls results in a large density of exposed surface reactive/catalytic sites. Because of these optimized electronic and surface structures, the material exhibits superior photocatalytic activity toward the hydrogen evolution reaction (HER).
Ultrahigh-Q on-chip silicon–germanium microresonators (2022)

Total Synthesis of Abyssomicin C and atrop‐Abyssomicin C (2006)

Into the abyss: A total synthesis of abyssomicin C (1) through a metathesis-based strategy offers a highly convergent approach to the construction of analogues. A novel and potent atropisomer of the natural product 1 was thus discovered, namely atrop-abyssomicin C (2), which reveals subtle yet important structural differences to 1 (see structures; O red, C gray, H white).
KinectFusion rapid 3D reconstruction and interaction with Microsoft Kinect (2012)

Using a Microsoft Kinect camera, the KinectFusion system enables a low-cost way for a user to digitally reconstruct a whole room and its contents within seconds. As the space is explored, new views of the arbitrary scene and objects are revealed and these are fused into a single 3D model. The 6DoF pose of the camera is tracked in real-time using a method which directly uses the point-based depth data of Kinect, and requires no feature extraction or feature tracking. Once the 3D pose of the camera is known, each depth measurement from the sensor can be integrated into a volumetric representation. Kinect Fusion enables many Augmented Reality applications and 3D interaction such as multi-touch on arbitrary shaped surfaces.
Efficient Loading and Controlled Release of Benzophenone-3 Entrapped into Self-Assembling Nanogels (2010)

Benzophenone-3 (BZ-3), was successfully entrapped into nanogels prepared by a simple one-step method based on selfassembly of two water soluble polymers: a hydrophobically modified dextran (MD) and a β-Cyclodextrin polymer (pβ-CD). Isothermal titration microcalorimetry (ITC) and phase solubility experiments were performed at 4, 25 or 37°C to investigate the interaction of the hydrophobic BZ-3 with MD and pβ-CD. The BZ-3 entrapment efficiency, yield of nanogels formation, particle size, and BZ-3 release were also evaluated. BZ-3/pβ-CD interaction was characterized by association constants K= 5180 M-1 and K´= 2700 M-1, as determined by phase solubility and ITC experiments, respectively. Differences obtained in association constants values were discussed critically. Results indicate that both K and K´ decrease with increase in temperature. The strong interactions between BZ-3 and pβ-CD were characterized by a negative enthalpy change ( H) with entropic contribution (T S). Monodisperse nanogels were produced with an entrapment up to 75 % and yield up 84 %. BZ-3 was firmly entrapped into nanogels, as only the dilution of the nanogels led to its release. This system provides an advantage for sunscreen formulation to prevent systemic penetration of BZ-3. The ‘green’ (solvent free) preparation method, and the possibility of unlimited storage after freeze drying makes these nanogels valuable candidates for the entrapment of sun screen agents.
The state of quantum computing applications in health and medicine (2023)

Medicine, including fields in healthcare and life sciences, has seen a flurry of quantum-related activities and experiments in the last few years (although biology and quantum theory have arguably been entangled ever since Schrödinger's cat). The initial focus was on biochemical and computational biology problems; recently, however, clinical and medical quantum solutions have drawn increasing interest. The rapid emergence of quantum computing in health and medicine necessitates a mapping of the landscape. In this review, clinical and medical proof-of-concept quantum computing applications are outlined and put into perspective. These consist of over 40 experimental and theoretical studies. The use case areas span genomics, clinical research and discovery, diagnostics, and treatments and interventions. Quantum machine learning (QML) in particular has rapidly evolved and shown to be competitive with classical benchmarks in recent medical research. Near-term QML algorithms have been trained with diverse clinical and real-world data sets. This includes studies in generating new molecular entities as drug candidates, diagnosing based on medical image classification, predicting patient persistence, forecasting treatment effectiveness, and tailoring radiotherapy. The use cases and algorithms are summarized and an outlook on medicine in the quantum era, including technical and ethical challenges, is provided.
A prospective multicentre registry of the procedural and long-term clinical and angiographic results of stent implantation using a Dylyn coated coronary stent system (2004)

A Dylyn coated coronary stent system is well tolerated and has excellent short-term results. The amount of angiographic restenosis at 6 months, however, is considerable, but comparable to other non-drug-eluting stent systems.
