An Implementation of Conflict-Free Offline Permutation on the GPU (2012)

The Discrete Memory Machine (DMM) is a theoretical parallel computing model that captures the essence of the shared memory access of GPUs. The bank conflicts should be avoided for maximizing the bandwidth of the shared memory access. Offline permutation of an array is a task to copy all elements in array a into array b along a permutation given in advance. The main goal of this paper is to implement a conflict-free permutation algorithm on the DMM in a GPU. We have also implemented straightforward permutation algorithms on the GPU. The experimental results for 1024 float numbers on NVIDIA GeForce GTX-680 show that a straightforward permutation algorithm takes 246ns and 877ns for random permutation and bit-reversal permutation, respectively. Quite surprisingly, our conflict-free permutation algorithm runs in 165ns both for random permutation and for bit-reversal permutation although it performs more memory access operations. It follows that our conflict-free permutation is 1.5 times faster for random permutation and 5.3 times faster for bit-reversal permutation.
Excimer laser coronary angioplasty: Results in restenosis versus de novo coronary lesions (1992)

There is limited information regarding the use of excimer laser coronary angioplasty (ELCA) in patients with restenotic lesions. The purpose of this investigation was to compare the results of ELCA in patients with restenosis following prior PTCA with results obtained in de novo (no restenosis) patients. A retrospective review was obtained of all patients undergoing attempted ELCA at each of the 12 participating clinical investigative centers. There were 620 patients in the prior restenosis group and 949 in the de novo group. Both laser success (88% vs 78%) and procedural success (92% vs 88%) were higher in restenosis lesions compared with de novo lesions (P less than 0.001). Six-month follow-up was available in 40% of patients. Restenosis occurred in 49% of the prior restenosis group vs 44% of the de novo group (P nonsignificant) but death was more common in the de novo group (2.2 vs 0.4%, P = 0.01). ELCA can be performed with a high success rate in patients with restenosis following prior balloon angioplasty but recurrent restenosis following laser procedure remains a significant problem.
Mixed Kinematics and Camera Based Vehicle Dynamic Sideslip Estimation for an RC Scaled Model (2018)

Vehicle side slip angle is at the basis of many vehicle dynamics control systems. Many methods are available to estimate side-slip angle using on board sensors (usually accelerometers and gyros). The technical advances pertaining autonomous vehicles made an additional kind of sensor available: cameras. This study develops a mixed kinematic vision-based side slip angle estimation. The proposed algorithm merges the information of a commercial grade inertial measurement system, wheel encoders and information from a camera. The camera measurement are integrated in a Kalman filter observer. The paper implements and tests the approach on an instrumented RC scale vehicle, comparing the proposed approach against a kinematic based estimation. Experimental results show a decrease of a factor between 2 and 10 (depending on the type of maneuver) of the estimation mean squared error.

Tetraorganylborate salts as convenient precursors for photogeneration of tertiary amines (1998)

Photoreactions of p-(benzoyl)benzyl trisubstituted ammonium tetraorganylborate salts for the generation of tertiary amines in solution and rigid matrices are described. Structural modification of the complexes allows study of the influence of steric and electronic effects on the photogeneration of amines. Flash photolysis, cyclic voltammetry and product analysis indicate that single electron transfer from borate to excited benzophenone is followed by homolytic C–N bond cleavage. Photoliberation of the tertiary amine is controlled by the rate of the electron transfer reaction.
Transcription termination and processing of transcripts from tRNA‐related Xenopus satellite DNA sequences (1987)

Nucleotide sequence homologies have been found between the transcriptional unit of a Xenopus laevis satellite DNA containing 1037-bp monomeric repeats and tRNA-coding genes. Since the tRNA-homologous region forms only part of the transcriptional unit, we have analyzed the size of transcripts being made after injection of cloned DNA into Xenopus oocyte nuclei. Incubation for 6 h mainly results in three RNA species comprising 130, 180 and 196 nucleotides, which originate at the same initiation site but terminate at different T stretches. Longer incubation reveals a complex pattern of smaller RNAs most likely resulting from 3'-end processing of primary transcripts. All these RNAs are related to tRNA, since they contain the tRNA-homologous region which is close to the 5' end of the transcription unit.
UDCT: Unsupervised data to content transformation with histogram-matching cycle-consistent generative adversarial networks (2019)

Abstract The segmentation of images is a common task in a broad range of research fields. To tackle increasingly complex images, artificial intelligence (AI) based approaches have emerged to overcome the shortcomings of traditional feature detection methods. Owing to the fact that most AI research is made publicly accessible and programming the required algorithms is now possible in many popular languages, the use of such approaches is becoming widespread. However, these methods often require data labeled by the researcher to provide a training target for the algorithms to converge to the desired result. This labeling is a limiting factor in many cases and can become prohibitively time consuming. Inspired by Cycle-consistent Generative Adversarial Networks’ (cycleGAN) ability to perform style transfer, we outline a method whereby a computer generated set of images is used to segment the true images. We benchmark our unsupervised approach against a state-of-the-art supervised cell-counting network on the VGG Cells dataset and show that it is not only competitive but can also precisely locate individual cells. We demonstrate the power of this method by segmenting bright-field images of cell cultures, a live-dead assay of C.Elegans and X-ray-computed tomography of metallic nanowire meshes.
Observation of spin structure related positive magnetoresistance in antiferromagnetically coupled magnetic multilayers (1993)

We report the observation of a previously unobserved positive magnetoresistance effect in several antiferromagnetically coupled magnetic multilayers. The effect is typically very small with the largest magnetoresistance values observed of less than 0.1% at 4.2 K. We find that the effect is common in magnetic multilayers comprised of magnetic layers of Fe and Co and spacer layers composed of elements from the left hand portions of the 4d and 5d transition metal periods. We propose the magnetoresistance is a consequence of Lorentz magnetoresistance and is unrelated to the giant magnetoresistance effect observed in related structures.
Genetic and functional evidence relates a missense variant in B4GALT1 to lower LDL-C and fibrinogen (2019)

Abstract Increased LDL-cholesterol (LDL-C) and fibrinogen are independent risk factors for cardiovascular disease (CVD). We identified novel associations between an Amish-enriched missense variant (p.Asn352Ser) in a functional domain of beta-1,4-galactosyltransferase 1 ( B4GALT1 ) and 13.5 mg/dl lower LDL-C (p=1.6E-15), and 26 mg/dl lower plasma fibrinogen (p= 9.8E-05). N-linked glycan profiling found p.Asn352Ser to be associated (p-values from 1.4E-06 to 1.0E-17) with decreased glycosylation of glycoproteins including: fibrinogen, ApoB100, immunoglobulin G (IgG), and transferrin. In vitro assays found that the mutant (352Ser) protein had 50% lower galactosyltransferase activity compared to wild type (352Asn) protein. Knockdown of b4galt1 in zebrafish embryos resulted in significantly lower LDL-C compared to control, which was fully rescued by co-expression of 352Asn human B4GALT1 mRNA but only partially rescued by co-expression of 352Ser human B4GALT1 mRNA. Our findings establish B4GALT1 as a novel gene associated with lower LDL-C and fibrinogen and suggest that targeted modulation of protein glycosylation may represent a therapeutic approach to decrease CVD risk.
Low nonlinearity dispersion-shifted fibers employing dual-shaped core profile with depressed cladding (2002)

Recently, dispersion-shifted fibers (DSFs) with large effective core areas have been widely studied and demonstrated by employing various index profiles. In the paper, we show that DSFs with effective core areas >85 /spl mu/m/sup 2/ and excellent bending loss performance can be realized by properly optimizing the dual-shaped core profile, which is one of the major refractive index profiles employed by the currently mass-produced standard DSFs.
Pump-linewidth-tolerant wavelength multicasting using soliton Kerr frequency combs (2017)

We experimentally demonstrate pump-linewidth-tolerant wavelength multicasting using microresonator-based soliton Kerr frequency combs. When Kerr comb lines serve as coherent pumps in a periodically poled lithium niobate waveguide, the linewidth of the multicast signal almost remains that of the original signal at different linewidths of Kerr combs, ranging from 100&#x00A0;kHz to 1&#x00A0;MHz. However, in conventional multicasting where free-running (FR) pumps are used, the linewidth of the converted signal significantly increases. Furthermore, the error vector magnitude (EVM) performance demonstrates eight-fold error-free multicasting of 10&#x00A0;Gbaud 16-quadrature amplitude modulation signals, even when the linewidths of the Kerr combs are as broad as 1&#x00A0;MHz (no Kalman filtering algorithm in the receiver). In contrast, the EVM performance of the signal copy is degraded with an FR laser as a dummy pump.
Liquid silver tris(perfluoroethyl)trifluorophosphate salts as new media for propene/propane separation (2016)

A series of silver tris(perfluoroethyl)trifluorophosphate (Ag[FAP]) complexes with various ligands (acetonitrile ACN, chloroacetonitrile Cl-ACN, acrylonitrile acryl-CN, pyridine py, ethylenediamine en and propene C<sub>3</sub>H<sub>6</sub>) have been synthesized starting from Ag[NO<sub>3</sub>] and K[FAP] using three different routes. Physicochemical properties as well as crystal structures ([Ag(ACN)<sub>2/4</sub>][FAP], [Ag(py)<sub>2</sub>][FAP]) were determined and the suitability of such Ag salts for propene/propane separation processes was investigated. The investigated silver complexes exhibit either low melting points or form liquid complexes when contacted with gaseous propene at 30 °C. This makes them promising separation materials for both liquid membranes and absorber fluids due to their high silver content and significant propene capacity. Single (iGSC) and mixed (NMR) gas solubilities as well as diffusion coefficients (PFG-NMR) of propene and propane were determined to predict the theoretical selectivity of solubility, membrane selectivity, capacity and transport properties of the silver salts according to the solution diffusion model. A strong influence of the number and type of ligands on chemical complexation, physicochemical properties and separation performance has been observed.
Development and characterization of a gastroretentive dosage form composed of chitosan and hydroxyethyl cellulose for alendronate (2013)

In this study, alendronate, the most commonly used biphosphonate for treating osteoporosis, was formulated as gastroretentive dosage form (GRDF) tablets to enhance its oral bioavailability. GRDF tablets were characterized with the effects of different molecular weights (MWs) of chitosan (CS) and hydroxyethyl cellulose (HEC) at various ratios on swelling, floating, and physical integrity. The CS component was formed using various acids: acetic, lactic, malic, succinic, and citric, and a high viscosity grade of HEC was selected. The results demonstrated that the swelling ratios of the formulations comprising high MW CS were lower than those of low or medium MW CS when salts were formed with any countering acids except for acetic acid. The decreasing ranking of the swelling rates was: CS-citrate > CS-malate > CS-lactate > CS-succinate > CS-acetate. A negative correlation was found between the pKa of the respective countering acid and the swelling rate. The swelling rate was promoted if an acidic salt of CS with a lower water content was incorporated, while it became slower when tablet hardness was higher or the compression force to form tablets was increased. Although HEC did not contribute to swelling or floating, it played a role in maintaining structural integrity. A prolonged dissolution profile of alendronate GRDF tablets developed in this study was observed.
Best Practice Guidelines for Hip Arthroscopy in Femoroacetabular Impingement: Results of a Delphi Process (2019)

Objectives: Treatment algorithms for the arthroscopic management of femoroacetabular impingement syndrome (FAI) remain controversial due to a paucity of evidence-based guidance. Consequently, significant variability in clinical practice exists between different practitioners, necessitating expert consensus. The purpose of this study is to establish Best Practice Guidelines (BPG) using formal techniques of consensus building among a group of experienced hip arthroscopists driven by the results of a systematic review and meta-analysis. The scope of these guidelines includes preoperative recommendations, intraoperative practices, and postoperative protocols. Methods: The validated Delphi process and nominal group technique (NGT), utilized by the Centers for Disease Control and peer-reviewed orthopedic literature, were used to formally derive consensus among 15 surgeons in North America. Participants were surveyed for current practices, presented with the results of a meta-analysis and systematic literature review, and asked to vote for or against inclusion of non-leading, impartially-phrased items during three iterative rounds while preserving the anonymity of participants’ opinions. Agreement greater than 80% was considered consensus, and items near consensus (70%-80% agreement) were further queried using the NGT in a moderated group session at the American Orthopaedic Society for Sports Medicine (AOSSM) annual meeting. Results: Participants had a mean of 12.3 years of practice (range: 1-29 years) and performed an annual mean of 249 (range 100 to 500+) hip arthroscopies, with a combined total of approximately 52,580 procedures. Consensus was reached for the creation of BPG consisting of 27 preoperative recommendations, 15 intraoperative practices, and 10 postoperative protocols. The final checklist was supported by 100% of participants. Conclusion: We developed the first national consensus-based Best Practice Guidelines for the surgical and nonsurgical management of FAI. The resulting consensus items can serve as a tool to reduce the variability in pre-, intra-, and postoperative practices and guide further research for arthroscopic management of FAI.
Vehicle Optimal Torque Vectoring Using State-Derivative Feedback and Linear Matrix Inequality (2012)

A controller assistant system is developed based on the closed-form solution of an offline optimization problem for a four-wheel-drive front-wheel-steerable vehicle. The objective of the controller is to adjust the actual vehicle attitude and motion according to the driver's manipulating commands. The controller takes feedback from acceleration signals, and the imposed conditions and limitations on the controller are studied through the concept of state-derivative feedback control systems. The controller gains are optimized using linear matrix inequality (LMI) and genetic algorithm (GA) techniques. Reference signals are calculated using a driver command interpreter module (DCIM) to accurately interpret the driver's intentions for vehicle motion and to allow the controller to generate proper control actions. It is shown that the controller effectively enhances the handling performance and stability of the vehicle under different road conditions and driving scenarios. Although controller performance is studied for a four-wheel-drive front-wheel-steerable vehicle, the algorithm can also be applied to other vehicle configurations with slight changes.
Performance evaluation of Directional MAC protocol for Inter-vehicle communication (2005)

In this paper, the performance of directional MAC protocol, proposed in [T. Koriakis et al., June 2003], and IEEE 802.11 MAC protocol are compared for an inter-vehicle communication application. Actual vehicle movement in a city and highway road scenarios are used for simulating inter-vehicle communication among nodes in network simulator (ns-2). DMAC protocol was implemented in ns-2. The results obtained from simulations demonstrate the performance improvement of directional MAC protocol as compared to IEEE 802.11 MAC for inter-vehicle communication.

Loss analysis in perovskite photovoltaic modules (2019)

Hybrid metal halide perovskite-based thin-film photovoltaics have the potential to become the next generation of commercialized PV technology with certified power conversion efficiencies reaching 24% on 0.1 cm2 area devices. Recent efforts in upscaling of this technology resulted in an efficiency of 12.6% for 354 cm2 modules. Still, upscaling loss for perovskite-based photovoltaics is higher than for any other PV technology. In this study, we investigate these upscaling losses, with a focus on layer inhomogeneities, for devices with aperture area of 0.1, 4 and 100 cm2. With use of electro-luminescence, dark lock-in thermography, micro photoluminescence spectroscopy and electron spectroscopy we analyze and group layer inhomogeneities with minimal size of 10 m and compare loss mechanisms for radial and linear deposition techniques. Analysis leads us to defining processing pitfalls, where understanding and control of perovskite crystal formation plays the crucial role.
45-OR: Less Favorable Response to Anti-VEGF Therapy in Patients with Diabetic Macular Edema and Decreased Baseline Outer Retinal Layer Thickness (2022)

Early identification of patients who are more likely to respond to anti-VEGF therapy for diabetic macular edema (DME) would improve patient management and allow for more rapid assessment of new therapeutic targets. This study evaluated retinal thickness variables and their association with anti-VEGF therapy response in patients with DME. We identified patients at the Joslin Diabetes Center who received their first anti-VEGF injection for DME between 1/2016-12/20 and assessed mean change in visual acuity (VA) and central retinal thickness (RT) at 6 mos. A good VA or RT response to anti-VEGF therapy was defined using thresholds of letter and retinal thickness change as follows: eyes with baseline VA of ≥20/32, ≥5 letters; 20/40-20/70, ≥letters; ≤20/80, ≥15 letters and eyes with baseline RT of &amp;lt;375µm, &amp;gt;10%; 375-449µm, &amp;gt;20%; &amp;gt;449µm, &amp;gt;25%. A total of 151 eyes from 126 patients fell into the following responder groups: both VA and RT response (32.5%) , only VA response (21.9%) or RT response (11.3%) , and neither VA nor RT response (34.4%) , with 57.0% of all eyes exhibiting VA response and 43.7% exhibiting RT response. While diabetes duration, A1c, and blood pressure were not associated with responder group, decreased baseline thickness of the outer retinal layer (ORL) was more likely to be present in eyes with neither VA nor RT response (β=-.018; 95% CI -0.03 to -0.01; P=.006) . Improvement in mean VA was associated with younger age (β=.004; 95% CI 0.001-0.007; P=.01) . Decreased baseline ORL thickness (β=-.003; 95% CI -0.0to -0.001; P=.01) and increased baseline inner retinal layer (IRL) thickness (β=.0004; 95% CI 0.0001-0.0007; P=.02) were associated with less VA gain at 6 mos. These findings suggest that decreased baseline ORL thickness is associated with less favorable outcome after anti-VEGF therapy and may be a potential biomarker for treatment response in patients with DME.
