Large-Scale Synthesis of Six-Nanometer-Wide ZnO Nanobelts (2004)

Using a thin film of metallic tin as catalyst, ultrasmall single-crystalline zinc oxide nanobelts have been synthesized in large quantity using a simple solid−vapor technique. The nanobelts have an average width of 5.5 nm and a narrow size distribution of ±1.5 nm. The nanobelts grew along the [0001] direction, with (21̄1̄0) top/bottom surfaces and (011̄0) side surfaces. Photoluminescence measurement showed a blue shift in the emission spectrum compared to that acquired from ZnO nanobelts of ∼200 nm in width. These ultrafine nanobelts should be good candidates for investigating size-induced electrical and optical properties of functional oxides.

Regulation of adenylyl cyclase in LTP (1995)

Abstract Our results on hippocampal long-term potentiation are considered in the context of Xia et al.'s hypothesis. Whereas the target article proposes presynaptic PKC involvement in adenylyl cyclase activation by phosphorylation of nenromodulin, we suggest an additional postsynaptic role involving RC3/nenrogranin. Finally, we examine the possibility that the adenylyl cyclase mutant mouse may display normal learning with a selective impairment of memory.

Acoustic gas thermometry (2014)

We review the principles, techniques and results from primary acoustic gas thermometry&#13;\n(AGT). Since the establishment of ITS-90, the International Temperature Scale of 1990,&#13;\nspherical and quasi-spherical cavity resonators have been used to realize primary AGT in the&#13;\ntemperature range 7K to 552 K. Throughout the sub-range 90K &lt; T &lt; 384 K, at least two&#13;\nlaboratories measured (T − T90). (Here T is the thermodynamic temperature and T90 is the&#13;\ntemperature on ITS-90.) With a minor exception, the resulting values of (T −T90) are mutually&#13;\nconsistent within 3 × 10−6 T . These consistent measurements were obtained using helium and&#13;\nargon as thermometric gases inside cavities that had radii ranging from 40mm to 90mm and&#13;\nthat had walls made of copper or aluminium or stainless steel. The AGT values of (T − T90)&#13;\nfall on a smooth curve that is outside ±u(T90), the estimated uncertainty of T90. Thus, the&#13;\nAGT results imply that ITS-90 has errors that could be reduced in a future temperature scale.&#13;\nRecently developed techniques imply that low-uncertainty AGT can be realized at&#13;\ntemperatures up to 1350K or higher and also at temperatures in the liquid-helium range.
Precision medicine in diabetic nephropathy and chronic kidney disease (2021)

Progressive chronic kidney disease (CKD) in individuals with type 2 diabetes mellitus is a global public health problem accompanied by substantial comorbidities and reduced life expectancy. In this respect, CKD leading to uremia can be seen as a systemic disease with a critical impact on virtually all organ systems. Thus it is of particular importance to identify patients with incipient CKD and ongoing CKD progression, but the individual course of CKD is challenging to predict. Patterns of progression in persons with CKD include linear and nonlinear trajectories of glomerular filtration rate (GFR) loss. Kidney function can also remain stable for years, especially in the elderly. In particular, one-fifth of individuals show a substantial GFR decline in the absence of high albuminuria (nonproteinuric CKD), rendering albuminuria less suitable for predicting the progression in such individuals.
Conductivity and Viscosity of PC-DEC and PC-EC Solutions of LiPF[sub 6] (2003)

Conductivity κ and viscosity η of propylene carbonate (PC)-diethyl carbonate (DEC) and PC-ethylene carbonate (EC) solutions of were experimentally determined, the former at salt molalities from 0.2 to solvent compositions from 0 to 0.7 weight fraction of DEC and 0 to 0.6 weight fraction of EC, and temperatures θ from 60 to the latter indirectly and qualitatively through measuring the glass transition temperature in the same ranges of and The increased with and decreased with of DEC but increased with of EC, indicating a concurrent change in the η of the solutions. The κ of the PC-DEC solution of peaked in both and thus forming a dome in its 3D presentation in the coordinates, while that of the PC-EC solution peaked only in resulting in an arch-shaped surface. As θ lowered, these κ surfaces fell in height and shifted in the direction of low η. These observations correlated well with the changes of dielectric constant ɛ and viscosity η of the solutions with the same set of variables. More detailed study of the effects of DEC and EC on the κ of PC solution of demonstrated the benefit of having a low-η solvent component in an electrolyte for it to have a decent κ at low θ and the independence on θ of ion association in these solutions in support of an earlier finding. The data of the PC-DEC solution of were fit with the Vogel-Tamman-Fulcher equation for an evaluation of its apparent activation energy and its vanishing mobility temperature the former shown to be a simple surface in the coordinates slanting up in the direction of high η, and the latter another one slanting up in the same direction and lying beneath the surface of by more than ten degrees. © 2003 The Electrochemical Society.

SCR inverter commutated by an auxiliary impulse (1964)

THE KEY to efficient inverter circuits, using silicon controlled rectifiers (SCR's), is the method of commutation — the process of transferring current from one controlled rectifier to another. When feedback rectifiers are used to provide an alternative path for reactive load current, the size of the commutating components can be greatly reduced, <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> and the commutation transient takes the form of an impulse. This impulse must be large enough to extinguish the current in the conducting controlled rectifier and long enough to provide inverse voltage for the required turn-off time. In many inverters, <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> commutation is initiated by turning on the controlled rectifier that is complementary to the one being turned off. This paper describes a new circuit in which the commutating impulse is initiated by gating auxiliary controlled rectifiers. The inductance-capacitance (LC) pulse circuit is separate from the main power circuit except during commutation.
Computation of Rank and Select Functions on Hierarchical Binary String and Its Application to Genome Mapping Problems for Short-Read DNA Sequences (2009)

Abstract We have developed efficient in-practice algorithms for computing rank and select functions on a binary string, based on a novel data structure, a hierarchical binary string with hierarchical accumulatives. It efficiently stores decomposed information on partial summations over various scales of subregions of a given binary string, so that the required space overhead ratio is only about 3.5% irrespective of the string length. Values of rank and select functions are computed hierarchically in [(log(2)n)/8] iterations, where n is the string length. For example, for an unbiased random binary string of 64 G bits, each value of these functions can be computed in about a microsecond, on average, on a single 3.0-GHz CPU using 8+ GB of memory. We also present their applications to genome mapping problems for large-scale short-read DNA sequence data, especially produced by ultra-high-throughput new-generation DNA sequencers. The algorithms are applied to the binarization of the Burrows-Wheeler transform of the human genome DNA sequence. For the sake of high-speed performance, we adopted a somewhat stringent mapping condition that allows at most a single-base mismatch (either a substitution, insertion, or deletion of a single base) per query sequence. An experimentally implemented program mapped several thousands of sequences per second on a single 3.0-GHz CPU, several times faster than ELAND, a widely used mapping program with the Illumina-Solexa 1G analyser.
Spine Research Is Multidisciplinary (2016)

Spine research has advanced substantially over the past 25 years through a highly multidisciplinary process. Through early work on fracture healing, osteosynthesis, tissue engineering, and joint biomechanics, researchers discerned 2 main areas of study: musculoskeletal biomechanics and musculoskeletal regeneration. Investigations of the spine continually move from the research bench-through endeavors that incorporate basic science, biology, biomaterials, mechanical testing, finite element analysis, and mathematical modeling-to the bedside-through treatments, devices, and procedures designed to improve patient health while safeguarding quality of life.
Near Maximum-Likelihood Detector and Channel Estimator for Uplink Multiuser Massive MIMO Systems with One-Bit ADCs (2015)

In massive multiple-input multiple-output (MIMO) systems, it may not be power efficient to have a high-resolution analog-to-digital converter (ADC) for each antenna element. In this paper, a near maximum likelihood (nML) detector for uplink multiuser massive MIMO systems is proposed where each antenna is connected to a pair of one-bit ADCs, i.e., one for each real and imaginary component of the baseband signal. The exhaustive search over all the possible transmitted vectors required in the original maximum likelihood (ML) detection problem is relaxed to formulate an ML estimation problem. Then, the ML estimation problem is converted into a convex optimization problem which can be efficiently solved. Using the solution, the base station can perform simple symbol-by-symbol detection for the transmitted signals from multiple users. To further improve detection performance, we also develop a two-stage nML detector that exploits the structures of both the original ML and the proposed (one-stage) nML detectors. Numerical results show that the proposed nML detectors are efficient enough to simultaneously support multiple uplink users adopting higher-order constellations, e.g., 16 quadrature amplitude modulation. Since our detectors exploit the channel state information as part of the detection, an ML channel estimation technique with one-bit ADCs that shares the same structure with our proposed nML detector is also developed. The proposed detectors and channel estimator provide a complete low power solution for the uplink of a massive MIMO system.
The Recombinant Phage Lysin LysK Has a Broad Spectrum of Lytic Activity against Clinically Relevant Staphylococci, Including Methicillin-Resistant Staphylococcus aureus (2005)

This study concerns the cloning, characterization, and expression of the lysin (LysK) from staphylococcal phage K in Lactococcus lactis. Lactococcal lysates containing recombinant LysK were found to inhibit a range of different species of staphylococci isolated from bovine and human infection sources, including methicillin-resistant Staphylococcus aureus. LysK thus has potential as an antimicrobial for applications in the prevention and/or treatment of infections caused by staphylococci.
Artifact Lifecycle Discovery (2015)

Artifact-centric modeling is an approach for capturing business processes in terms of so-called business artifacts — key entities driving a company's operations and whose lifecycles and interactions define an overall business process. This approach has been shown to be especially suitable in the context of processes where one-to-many or many-to-many relations exist between the entities involved in the process. As a contribution towards building up a body of methods to support artifact-centric modeling, this article presents a method for automated discovery of artifact-centric process models starting from logs consisting of flat collections of event records. We decompose the problem in such a way that a wide range of existing (non-artifact-centric) automated process discovery methods can be reused in a flexible manner. The presented methods are implemented as a package for ProM, a generic open-source framework for process mining. The methods have been applied to reverse-engineer an artifact-centric process model starting from logs of a real-life business process.
Septa design study for volumetric imaging in positron emission tomography (2002)

Positron emission tomography (PET) has become an essential imaging tool to localize tumors in diagnostic radiology and to monitor the size of a lesion before and during the treatment in oncology. Currently, commercial PET cameras operate only in two extreme modes: i) no-septa: three-dimensional (3-D) acquisition mode, also called volumetric imaging; and ii) all-septa-in: two-dimensional (2-D) acquisition mode, also called multislice imaging. In this paper, intermediate septa designs in the brain mode have been sought to minimize the scatter and accidental coincidences with acceptable sensitivity loss. To achieve this goal, Monte Carlo simulations were performed to evaluate possible septa designs. Information about septal penetration, absorption and scattering components from simulations guided us to modify the thickness and total number of septa in the new configurations. Count rate performances of three septa configurations were measured on our experimental high resolution PET camera with 3.85-cm axial field-of-view (AFOV); the measurements were compared with the simulation results. No-septa configuration had lower noise equivalent count (NEC) compared the other two configurations because of small AFOV Monte Carlo simulations were performed to predict the count rate performances of seven septa configurations for 13.1-cm AFOV. In the large AFOV, because of increased number of line of responses, NEC rate for no-septa case peaked rapidly at 0.07 /spl mu/Ci/cc. No-septa configuration is not recommended for high count rate studies. In this case where activity density is 0.3 /spl mu/Ci/cc or more, 10-septa and 15-septa configurations performed better than the other configurations. Intermediate 5-septa designs with variable septum length performed better between 0.07-/spl mu/Ci/cc and 0.3-/spl mu/Ci/cc range which represents the clinical activity level for /sup 18/F-FDG brain studies.
Genetic Regulation of Bone Mass (2006)

INTRODUCTION Estrogen deficiency arising after the menopause or upon surgical removal of the ovaries leads to accelerated bone loss and promotes the development of postmenopausal osteoporosis in approximately one-third of the female population1. The primary consequence of the relative lack of estrogen is an increase in bone resorption, which can be attributed to marked increases in both the number and resorptive activity of osteoclasts2. Although bone formation also shows a notable increase upon the propagation of estrogen deficiency, the rise in resorption exceeds the increase in formation, the net changes leading to loss of bone mass. While bone resorption is carried out by osteoclasts, the paths by which estrogen exerts its inhibitory effects on these cells are still under debate. Although osteoclasts possess estrogen receptors and thus can be direct targets of estrogen action, a considerable part of the effect is believed to be indirect and mediated by osteoblasts and various cells of the immune system3. Research attempting the clarification of how estrogen acts on bone metabolism includes: the direct effects of sex steroids on osteoclasts investigated in simple in vitro systems; the impact of sex steroid receptor deficiency on osteoclastic function and skeletal homeostasis using data from estrogen and androgen receptor knock-out mice; and finally the in vivo effects of sex steroids on bone turnover assessed in various clinical settings. The current review combines these three major approaches to bring forward the present understanding of the action of sex steroids on osteoclast function and overall bone turnover.
Multiview point cloud kernels for semisupervised learning [Lecture Notes] (2009)

In semisupervised learning (SSL), a predictive model is learn from a collection of labeled data and a typically much larger collection of unlabeled data. These paper presented a framework called multi-view point cloud regularization (MVPCR), which unifies and generalizes several semisupervised kernel methods that are based on data-dependent regularization in reproducing kernel Hilbert spaces (RKHSs). Special cases of MVPCR include coregularized least squares (CoRLS), manifold regularization (MR), and graph-based SSL. An accompanying theorem shows how to reduce any MVPCR problem to standard supervised learning with a new multi-view kernel.
High-resolution spectroscopy and emission decay in concentrated Nd:YAG ceramics (2002)

The high-resolution spectroscopic and emission-decay investigation of highly concentrated (up to 9 at. %) Nd:YAG ceramics indicates that the state of the Nd3+ ion in these materials is similar to that of diluted crystals. The increased relative intensities of the spectral satellites connected with ensembles of Nd ions in near-lattice sites at high Nd concentrations CNd is consistent with the predictions of the statistics of the random placement of these ions at the available lattice sites. The room-temperature transmission spectra show that the resonant pump in the emitting level 4F3/2, including the hot-band pump Z2→R1 and Z3→R2, can be efficient at high CNd, with important effects in the reduction of the pump quantum defect and of the corresponding heat generation under the pump. The accelerated 4F3/2 emission decay at high CNd is consistent with the increased efficiency of the energy transfer, including the contribution of migration-assisted transfer processes. The calculated emission quantum efficiency η and the figure of merit ηCNd indicate that the concentrated Nd:YAG components can be used for construction of efficient solid-state lasers in free-generation or low-storage regimes, and, coupled with the hot-band resonant pump in the emitting level, they could enable the scaling of Nd:YAG lasers to high powers.
A Ka-band narrow bandpass filter using LTCC technology (2003)

A Ka-band low-temperature co-fired ceramic (LTCC) narrow bandpass filter (BPF) is presented first. This BPF shows a very narrow 3 dB fractional bandwidth of 4.5% centered at 28.7 GHz. The advantages of multilayered LTCC technology such as high integration and vertical stacking capabilities were employed to design a three-dimensional interdigital end-coupled embedded microstrip narrow BPF. The difficulties in controlling the precise distance between two adjacent resonators in LTCC end-coupled BPF were overcome by locating the resonators on different layers. The measured insertion loss is 3 dB at 28.7 GHz.
Joint space narrowing progression quantification with joint angle correction in rheumatoid arthritis (2022)

Rheumatoid arthritis is a form of autoimmune disease characterized by synovitis that can ultimately cause joint deformities and impaired functioning. The cartilage destruction is one of the most important indicators for diagnosis and treatment of Rheumatoid arthritis, and it is radiographically manifested as joint space narrowing. In this study, we propose a joint location detection method and a sub-pixel accurate method for quantifying joint space narrowing progression with a joint angle correction. The proposed joint location detection method can detect the location of 14 joints from a given hand radiographic image, the error of 89.13% joints is less than 3 pixels (spatial resolution: 0.175 mm/pixel). In our previous works, we measured joint space narrowing progression between a baseline and its follow-up finger joint images by using partial image phase only correlation. We found that the inconsistency of joint angles may lead to characteristic mismatch and thus affect the accuracy of joint space narrowing quantification. In this work, we introduce rotation invariant phase only correlation in joint space narrowing quantification for joint angle correction. In our experiment, the improved quantification method can effectively manage the mismatch due to the inconsistency of joint angles.
NMR Microscopy: A Tool for Measuring Monomer Diffusion in Supercritical CO2 (2006)

Abstract Summary: The diffusion of styrene into linear low density polyethylene in a solution of supercritical CO 2 was investigated using NMR microimaging. For both pure styrene and styrene dissolved in supercritical CO 2 , the diffusion was found to follow Fickian kinetics. Supercritical CO 2 was found to enhance the rate and extent of diffusion of styrene into the substrate by up to three times under the conditions of this investigation, compared to pure styrene. NMR imaging was used to measure the concentration profiles of the styrene penetrants in real time, and the results were fitted to a Fickian model for diffusion. At a CO 2 pressure of 150 bar and temperature of 40 °C, the diffusion coefficient of a 30 wt‐% solution of styrene into LLDPE was calculated to be 1 × 10 −11 m 2 · s −1 . This is significantly faster than the diffusion coefficient measured for pure styrene diffusion at 40 °C (3 × 10 −12 m 2 · s −1 ). The diffusion coefficients determined by gravimetric analysis were slightly higher than those determined by the imaging method. This was probably due to residual styrene and/or polystyrene adhering to the surface of the films in the gravimetric technique.
