Differential Diagnosis of Lower Extremity Enlargement in Pediatric Patients Referred with a Diagnosis of Lymphedema (2010)

"Lymphedema" is not a generic term. Approximately one-fourth of pediatric patients with a large lower extremity are misdiagnosed as having lymphedema; the most commonly confused causes are other types of vascular anomalies. History, physical examination, and often radiographic studies are required to differentiate lymphedema from other conditions to ensure the child is managed appropriately.
Quantitative Analysis of Prenylated RhoA Interaction with Its Chaperone, RhoGDI (2012)

Small GTPases of the Rho family regulate cytoskeleton remodeling, cell polarity, and transcription, as well as the cell cycle, in eukaryotic cells. Membrane delivery and recycling of the Rho GTPases is mediated by Rho GDP dissociation inhibitor (RhoGDI), which forms a stable complex with prenylated Rho GTPases. We analyzed the interaction of RhoGDI with the active and inactive forms of prenylated and unprenylated RhoA. We demonstrate that RhoGDI binds the prenylated form of RhoA·GDP with unexpectedly high affinity (K(d) = 5 pm). The very long half-life of the complex is reduced 25-fold on RhoA activation, with a concomitant reduction in affinity (K(d) = 3 nm). The 2.8-Å structure of the RhoA·guanosine 5'-[β,γ-imido] triphosphate (GMPPNP)·RhoGDI complex demonstrated that complex formation forces the activated RhoA into a GDP-bound conformation in the absence of nucleotide hydrolysis. We demonstrate that membrane extraction of Rho GTPase by RhoGDI is a thermodynamically favored passive process that operates through a series of progressively tighter intermediates, much like the one that is mediated by RabGDI.

Computational model for the dynamic stabilization of the Rayleigh-Bénard instability in rectangular enclosures (2011)

When fluid within a container is heated from the bottom, onset of convection occurs when Rayleigh number, gβΔTℓ3νχ, exceeds some critical value. If an acoustic field is imposed on the fluid in the container, the critical Rayleigh number is a strong function of the frequency and amplitude of that acoustic field as noted by Swift and Backhaus [J. Acoust. Soc. Am. 126(5), 2009]. Results will be reported for a linear model constructed to predict the modified critical Rayleigh number, based on a full field solution of the hydrodynamic equations using the approach of Gelfgat [J. Comp. Phys. 156, 1999]. The spatial portion of the differential equations was solved using the Galerkin method, and the dynamic stability was determined using Floquet analysis. One of the benefits of the approach compared to the averaging methods used by Gershuni and Lyubimov, [Thermal Vibration Convection (Wiley, New York, 1998)] is that the parametric stability boundary can also be recovered. This study includes a variety of container aspect ratios, boundary conditions, and Rayleigh numbers ranging from 103 to 108.

Global Topology Optimization in Two-Dimensional Supersonic Flow (2018)

In order to obtain a global topology optimal solution at supersonic flow conditions, it is necessary to solve efficiently high dimensional optimization problems with nonlinear discontinuous performance functions. As a countermeasure to solve these complicated optimization problems, we developed a novel optimization method which uses machine learning techniques such as DBSCAN clustering method and Support Vector Machine two-classes classification method. The developed method can explore the global optimum solution without probabilistic information such as variance calculated by Gauss Process Regression. In the test cases of multimodal/discontinuous functions, the developed method could obtain global optimal solutions superior to a conventional optimization method utilizing the EI acquisition function. Since the developed method uses only the predicted performance values to explore the global optimal solution, it can combine with any response surface methods such as Kernel Ridge Regression, Neural Network, Support Vector Regression, RBF Network, Reverse Distance Weighting Method and so on. In other words, when the developed method combines with response surface methods with higher adaptability to high dimensional problems, it will be able to solve high dimensional optimization problems efficiently.
Reconstruction of multiview images taken with non-regular sampling sensors (2014)

Increasing spatial image resolution is a widely discussed area in the field of image processing. In this paper, we present an efficient reconstruction approach for high-resolution images, taken with irregularly shielded low-resolution sensors in a multiview setup. The approach is based on the sparsity assumption, meaning that natural images can be efficiently represented in a transform-domain using only few coefficients. Utilizing information from adjacent cameras results in a better reconstruction quality for the central high-resolution view. Since neighboring camera perspectives might differ in illumination, the information from adjacent views has to be adapted to the view to be reconstructed. The simulation results show that a proper incorporation of information from neighboring views leads to a PSNR gain of up to 2.20 dB compared to a state-of-the-art singleview reconstruction approach.
Comparison of Energy and Growth Yields for Desulfitobacterium dehalogenans during Utilization of Chlorophenol and Various Traditional Electron Acceptors (1998)

Desulfitobacterium dehalogenans grew with formate as the electron donor and 3-chloro-4-hydroxyphenylacetate (3-Cl-4-OHPA) as the electron acceptor, yielding Y(X/formate), Y(X/2e), and Y(X/ATP) ranging from 3.2 to 11.3 g of biomass (dry weight)/mol, thus indicating that energy was conserved through reductive dechlorination. Pyruvate was utilized as the electron donor and acceptor, yielding stoichiometric amounts of acetate and lactate, respectively, and a Y(X/reduced acceptor) of 13.0 g of biomass (dry weight)/mol. The supplementation of pyruvate-containing medium with additional electron acceptors, such as 3-Cl-4-OHPA, nitrate, fumarate, or sulfite, caused pyruvate to be replaced as the electron acceptor and nearly doubled the Y(X/ATP) (Y(X/acetate formed)). A comparison of the yields for 3-Cl-4-OHPA with those for other traditional electron acceptors indicates that the dehalogenation reaction led to the formation of similar amounts of energy equivalents. The various electron acceptors were used concomitantly with 3-Cl-4-OHPA in nonacclimated cultures, but the utilization rates and amounts utilized differed.
Exotic resonant level models in non-Abelian quantum Hall states coupled to quantum dots (2010)

In this paper, we study the coupling between a quantum dot and the edge of a non-Abelian fractional quantum Hall state. We assume the dot is small enough that its level spacing is large compared to both the temperature and the coupling to the spatially proximate bulk non-Abelian fractional quantum Hall state. We focus on the physics of level degeneracy with electron number on the dot. The physics of such a resonant level is governed by a $k$-channel Kondo model when the quantum Hall state is a Read-Rezayi state at filling fraction $\ensuremath{\nu}=2+k/(k+2)$ or its particle-hole conjugate at $\ensuremath{\nu}=2+2/(k+2)$. The $k$-channel Kondo model is channel symmetric even without fine tuning any couplings in the former state; in the latter, it is generically channel asymmetric. The two limits exhibit non-Fermi-liquid and Fermi-liquid properties, respectively, and therefore may be distinguished. By exploiting the mapping between the resonant level model and the multichannel Kondo model, we discuss the thermodynamic and transport properties of the system. In the special case of $k=2$, our results provide a distinct venue to distinguish between the Pfaffian and anti-Pfaffian states at filling fraction $\ensuremath{\nu}=5/2$. We present numerical estimates for realizing this scenario in experiment.
Randomized phase II study with window-design to evaluate anti-tumor activity of the survivin antisense oligonucleotide (ASO) ly2181308 in combination with docetaxel for first-line treatment of castrate-resistant prostate cancer (CRPC). (2013)

5019 Background: In prostate cancer, expression of survivin, a protein that inhibits apoptosis, is associated with resistance to taxanes and poor outcome. LY2181308 reduces survivin expression and consequently is expected to improve activity of taxanes, such as docetaxel. A randomized phase II study was conducted to assess the activity of the combination. Methods: Adult patients (pts) with CRPC, ECOG performance status &lt;2, and no bone or CNSmetastases were randomized 1:2 to standard docetaxel/prednisone every 21 days (Arm A) or standard therapy combined with LY2181308 given as a 3-hr IV infusion (Arm B). Analysis was planned and performed after 130 pts progressed or died. This assessment provided a 70% chance of detecting a difference in progression-free survival (PFS) at the 10% significance level. Initially, LY2181308 was given as a loading dose (3 consecutive days) and then as a weekly 3-hr IV maintenance dose. Arm B also included a window treatment with LY2181308 monotherapy equivalent to a 21-day cycle of docetaxel before starting combined treatment. The primary endpoint was PFS. Results: This study enrolled 154 pts. The median PFS for Arm B was 8.64 (90% CI, 7.39–10.45) months vs. 9.00 (90% CI, 7.00–10.09) months in Arm A, showing no statistical difference (log rank p=0.755). The median overall survival (OS) for Arm B was 27.04 (90% CI, 19.94–33.41) months vs. 29.04 (90% CI, 20.11–39.26) months for Arm A (log-rank p= 0.838). The PSA responses (&gt;50% reduction in PSA) were similar: 56.9% for Arm A and 56.1% in Arm B (p=0.856). Most pts had no pain or mild pain at baseline and during the active period. Pts treated in Arm B had a higher frequency of serious and nonserious adverse events (AEs) than those in Arm A. The observed AE and pharmacokinetic (PK) profiles were consistent with the known safety and PK profiles of LY2181308 and docetaxel. Conclusions: The addition of LY2181308 to a standard docetaxel/prednisone regimen showed no improvement in PFS, PSA response, and OS in first line CRPC pts. The safety profile of docetaxel and LY2181308 is predictable and consistent with the known safety profiles. Clinical trial information: NCT00642018.
Towards recency ranking in web search (2010)

In web search, recency ranking refers to ranking documents by relevance which takes freshness into account. In this paper, we propose a retrieval system which automatically detects and responds to recency sensitive queries. The system detects recency sensitive queries using a high precision classifier. The system responds to recency sensitive queries by using a machine learned ranking model trained for such queries. We use multiple recency features to provide temporal evidence which effectively represents document recency. Furthermore, we propose several training methodologies important for training recency sensitive rankers. Finally, we develop new evaluation metrics for recency sensitive queries. Our experiments demonstrate the efficacy of the proposed approaches.
NSAIDs for the Chemoprevention of Oral Cancer: Promise or Pessimism? (2004)

Position Sensorless Control of a Reluctance Synchronous Wind Generator Drive with an LC Inverter Filter (2015)

—A control structure for an inverter-fed high speed reluctance synchronous generator wind energy conversion system is proposed and investigated in this article. The novel combination of an LC inverter output filter and a hybrid position sensorless control method is used to ensure robustness and reliability of the system. The proposed LC inverter filter and position sensorless control method also allows the inverter unit to be stationed in the tower base instead of in the nacelle. With the LC filter, sinusoidal machine terminal voltages and reduced electromagnetic interference (EMI) from the tower supple cables are ensured. A new estimation method is developed to minimize current and voltages sensors in the drive system with the LC filter, whereby the machine’s stator quantities are estimated, requiring only parameter knowledge of the LC filter. The proposed hybrid position sensorless control algorithm uses the estimated stator quantities to estimate the rotor position. A high-frequency injection position sensorless control method is used at low speeds. The frequency of the high-frequency injection voltage is chosen close to the resonance frequency of the filter and machine model to amplify the high-frequency current response. Excellent dynamic performance of the proposed control drive system is obtained from a 9.6-kW laboratory reluctance synchronous generator drive system.
Microstructure and optical properties of submicron porous silicon thin films grown at low current densities (2000)

The mechanism of porous silicon (PS) film growth remains a debate among researchers. This study investigates the effect of current density (J) and anodization time (t) on the film thickness, optical properties, and microstructure of films grown at low current densities. The samples reported herein were generated from polished and unpolished 〈100〉 single crystal wafers, with resistivities of 0.1 and 0.6 Ω cm, respectively. Current densities of 1–10 mA/cm2 and anodization times ranging from 3 to 900 s were used. This work shows that film growth is at first linear but beyond a given anodization time (dependent on J), the film produced is not continuous, but is best described as a finite number of stacked sublayers with each sublayer having a unique microstructure, porosity, and optical response. This article also shows that as the PS film grows, second and third order peaks appear in the reflectance spectra. This data, together with modulations in the index of refraction spectra and visual evidence from cross-sectional scanning electron microscopy (SEM) images demonstrate that submicron PS thin films grown at low current densities have a multilayer structure. Above a certain thickness, the modulation in the properties due to the sublayers phases out and the films appear as if they were single layered films. SEM is used to show the progression, from cross-sectional imaging, from a layered or stacked PS film structure to an apparently homogeneous film with depth. When using low current densities, single layer films are only obtained at very short times.

A framework for considering opportunities and threats in distributed software development (2005)

In this paper we present an overview of the field of distributed development of software systems and applications (DD). Based on an analysis of the published literature, we consider threats to communication, coordination and control in DD caused by Temporal Distance, Geographical Distance, and Socio-Cultural Distance. The analysis results in a more complete framework for reasoning in the DD domain which should be a useful resource for both academic researchers and practitioners.
The Role of Seizure-RelatedSEZ6as a Susceptibility Gene in Febrile Seizures (2011)

Sixty cases of febrile seizures from a Chinese cohort had previously been reported with a strong association between variants in the seizure-related (SEZ) 6 gene and febrile seizures. They found a striking lack of genetic variation in their controls. We found genetic variation in SEZ6 at similar levels at the same DNA sequence positions in our 94 febrile seizure cases as in our 96 unaffected controls. Two of our febrile seizure cases carried rare variants predicted to have damaging consequences. Combined with some of the variants from the Chinese cohort, these data are compatible with a role for SEZ6 as a susceptibility gene for febrile seizures. However, the polygenic determinants underlying most cases of febrile seizures with complex inheritance remain to be determined.
On Combining Shortest-Path and Back-Pressure Routing Over Multihop Wireless Networks (2009)

Back-pressure based algorithms based on the algorithm by Tassiulas and Ephremides have recently received much attention for jointly routing and scheduling over multi-hop wireless networks. However a significant weakness of this approach has been in routing, because the traditional back-pressure algorithm explores and exploits all feasible paths between each source and destination. While this extensive exploration is essential in order to maintain stability when the network is heavily loaded, under light or moderate loads, packets may be sent over unnecessarily long routes and the algorithm could be very inefficient in terms of end-to-end delay and routing convergence times. This paper proposes new routing/scheduling back-pressure algorithms that not only guarantees network stability (through-put optimality), but also adaptively selects a set of optimal routes based on shortest-path information in order to minimize average path-lengths between each source and destination pair. Our results indicate that under the traditional back-pressure algorithm, the end-to-end packet delay first decreases and then increases as a function of the network load (arrival rate). This surprising low-load behavior is explained due to the fact that the traditional back-pressure algorithm exploits all paths (including very long ones) even when the traffic load is light. On the otherhand, the proposed algorithm adaptively selects a set of routes according to the traffic load so that long paths are used only when necessary, thus resulting in much smaller end-to-end packet delays as compared to the traditional back-pressure algorithm.
