An adaptive spatial diversity receiver for non-Gaussian interference and noise (1999)

Standard linear diversity combining techniques are not effective in combating fading in the presence of non-Gaussian noise. An adaptive spatial diversity receiver is developed for wireless communication channels with slow, flat fading and additive non-Gaussian noise. The noise is modeled as a mixture of Gaussian distributions and the expectation-maximization (EM) algorithm is used to derive estimates for the model parameters. The transmitted signals are detected using a likelihood ratio test based on the parameter estimates. The new adaptive receiver converges rapidly, its bit error rate performance is very close to optimum when relatively short training sequences are used, and it appears to be relatively insensitive to mismatch between the noise model and the actual noise distribution. Simulation results are included that illustrate various aspects of the adaptive receiver performance.
Increased synthesis of nitric oxide in rat brain cortex due to halogenated volatile anesthetics confirmed by EPR spectroscopy (2002)

The action of volatile anesthetics is coupled with an increase of NO content in the cortex dependent on NOS activity.
Design of compact RF choke for suppressing ground edge current in LTE mobile application (2015)

A radio frequency choke (RFC) is proposed for suppressing ground edge currents which lead to a degradation of antenna performance in a MIMO communication system. The proposed RFC is designed compactly in size of 14.88 mm × 10.98 mm, in order to implement compatibly in a high-integrated RF circuit board. For determining the isolation performance of proposed RFC, the experiments consist of a 50 Ω transmission line mounted on the proposed RFC, as well as the transmission coefficient of an electromagnetic wave passing through the line is observed. The isolation can be enhanced by implementing the proposed RFC structure in the MIMO antenna configuration. The achieved envelope correlation coefficient is less than 0.14 in LTE 2300 band and it can be regarded as a reliable result for improving the diversity performance in MIMO antenna system.
Magnetic Properties of High Bs Manganese Zinc Ferrites and Cooling Rate Dependence of Core Loss (2005)

Magnetic properties of manganese zinc ferrites with high saturation magnetic flux density (Bs) were investigated. Bs of more than 500 mT at 100°C was obtained with the composition where Fe2O3 is approximately 64 mol% or more. In Fe-rich compositions, an increased number of cation vacancies were generally observed. This causes changes in magnetic properties as time elapses. The cation vacancies also causes the deterioration of core loss (Pcv) and initial magnetic permeability. By sintering under low oxygen partial pressure (Po2), the number of cation vacancies decreased, however, Pcv increased. One cause of this is the decrease of electrical resistivity. The total electrical resistivity is dominated by that at grain boundary. We also studied the cooling rate, which controls the resistivity at grain boundary.
Challenge and Opportunity in Scaling‐Up Metathesis Reaction: Synthesis of Ciluprevir (BILN 2061) (2013)

This chapter describes the challenges and opportunities involved in developing a practical and efficient chemical process for ciluprevir through ring-closing metathesis (RCM). In particular, it highlights the efforts in developing the first scale-up of RCM reaction for potential commercialization. During the course of these studies, a number of critical parameters for the RCM reaction, such as the nature of the precatalysts, initiation site, and conformations of substrate/products, were studied which led to the successful development of a practical process for scaling up the RCM reaction. Also, the second generation ciluprevir process represents the optimal convergent strategy for the assembly of ciluprevir for its potential commercialization.

Device impact of photon recycling and luminescent coupling on InGaP/Si tandems (2015)

We numerically evaluate the device impact of photon re-absorption on InGaP/Si tandem solar cells using a coupled optical-electronic device model. The presented simulation results provide guidelines for designing high performance InGaP/Si tandem device. We find that including the effects of photon recycling (PR) and luminescent coupling (LC) results in a 12.5% increase in optimum top-cell thickness for a two-terminal configuration. Furthermore, PR and LC affect the sensitivity of the tandem's conversion efficiency to various device parameters. As the InGaP bulk lifetime increases, there is an absolute efficiency increase of up to 0.7% for the two-terminal as well as the four-terminal configuration. Considering PR and LC furthermore reduces the power generation sensitivity to shunting in the two-terminal configuration. For the four-terminal configuration, photon re-absorption has a less significant impact.
[18F]DCFPyL PET/CT imaging in prostate cancer patients: a prospective study on safety, lesion detection rate, and impact on management (2019)

651 Objectives: PET tracers targeting the prostate specific membrane antigen (PSMA) have shown promise to detect prostate cancer recurrence and metastases that are occult on conventional imaging. However, most studies reported to date are retrospective or involve a small number of subjects. The objective of this prospective study was to evaluate the lesion detection rate, safety, and impact on management of [18F]DCFPyL PET/CT for prostate cancer imaging.
 Methods: An interim analysis of the first 208 [18F]DCFPyL PET/CT patient scans done in an investigator-initiated clinical trial (clinicaltrials.gov identifier NCT03181867) was conducted. The inclusion criteria were: (1) known prostate cancer with biochemical recurrence after initial curative therapy with radical prostatectomy with PSA > 0.4 ng/mL followed by an additional measurement showing increase; (2) known prostate cancer with biochemical recurrence after initial curative therapy by radiation therapy with a PSA level > 2.0 ng/mL above nadir after radiation therapy; (3) castration resistant prostate cancer with minimum PSA of 2.0 ng/mL and castrate levels of testosterone (<1.7 nmol/L); (4) findings on other examinations that are suspicious but not conclusive for metastatic disease. The participants underwent [18F]DCFPyL PET/CT after informed consent was obtained. The localization and number of lesions was recorded as well as uptake of the five most active lesions. Referring physicians completed a pre- and post-test survey to determine impact on management.
 Results: Two hundred and eight subjects were evaluated. The lesion detection rates were: 60% (PSA 0.2 to <0.5), 83% (0.5 to <1.0), 73% (1.0 to <2.0), 94% (≥2.0). Many subjects had few lesions: 38.5% (1 lesion), 9.6% (2 lesions), 6.7% (3 lesions). By ANOVA analysis, the number of lesions was significantly related to PSA, but there was a large overlap in PSA ranges for number of lesion categories. Total lesion uptake was also significantly related to PSA values. There were no adverse events during scans. Twenty-two subjects reported mild adverse events after the scan; all resolved completely. Treatment intent changed in 64.4%, disease stage changed in 66.7%, and management plans changed in 87.8% following [18F]DCFPyL PET/CT imaging.
 Conclusions: [18F]DCFPyL is a safe and sensitive radiopharmaceutical for the detection of prostate cancer. It also improved decision making for referring physicians and changed management for the majority of participants.
Multi-Antenna Interference Cancellation for Black Space Cognitive Radio Communications (2015)

This paper focuses on multi-antenna interference rejection based black-space cognitive radio (BS- CR) schemes. The idea of BS-CR is to transmit secondary user (SU) signal in the same frequency band with the primary user (PU) such that SU's power spectral density is clearly below that of the PU, and no significant interference is inflicted on the PU receivers. Advanced interference cancellation techniques allow such operation mode, which enables effective reuse of the PU spectrum for short-distance communication. This study aims at investigating the performance of multi antenna based co-channel interference suppression at the secondary receiver. The interference suppression capability of minimum mean square error (MMSE) based multi-antenna Interference Rejection Combining (IRC) is analyzed under the BC-CR framework. The performance of the IRC scheme is examined under different modulation and diversity orders and interference levels. In our case study, the proposed secondary communication system uses OFDM based 802.11af technology operating in the terrestrial TV frequency band, within an active DVB-T transmission channel.
Real-Time Observation of Atomic Layer Deposition Inhibition: Metal Oxide Growth on Self-Assembled Alkanethiols (2014)

Through in situ quartz crystal microbalance (QCM) monitoring, we resolve the growth of a self-assembled monolayer (SAM) and subsequent metal oxide deposition with high resolution. We introduce the fitting of mass deposited during each atomic layer deposition (ALD) cycle to an analytical island-growth model that enables quantification of growth inhibition, nucleation density, and the uninhibited ALD growth rate. A long-chain alkanethiol was self-assembled as a monolayer on gold-coated quartz crystals in order to investigate its effectiveness as a barrier to ALD. Compared to solution-loading, vapor-loading is observed to produce a SAM with equal or greater inhibition ability in minutes vs days. The metal oxide growth temperature and the choice of precursor also significantly affect the nucleation density, which ranges from 0.001 to 1 sites/nm2. Finally, we observe a minimum 100 cycle inhibition of an oxide ALD process, ZnO, under moderately optimized conditions.

The Effect of Ketorolac Tromethamine, Methylprednisolone, and Platelet‐Rich Plasma on Human Chondrocyte and Tenocyte Viability (2013)

Intra-articular injections of pain-modifying or anti-inflammatory drugs are routinely given in orthopaedic practice. Among the many agents available for intra-articular injection, corticosteroids and local anesthetics are the most common in clinical practice. Potential detrimental side effects of intra-articular injections of corticosteroids and local anesthetics have prompted investigation into alternative treatment options such as combinations of PRP and ketorolac tromethamine. In vitro evaluation of their effect on cell viability might build a basis for further translational research and clinical application.
Ultrafast myocardial elastography using coherent compounding of diverging waves during simulated stress tests: An in vitro study (2017)

Objective myocardial deformation assessment during stress tests could help clinicians to better diagnose myocardial ischemia. However, the use of conventional focused echocardiography is compromised at increased heart rates due to its limited lateral field of view and frame rate. Ultrafast echocardiography using coherent compounding of diverging waves improves temporal resolution while maintaining a large field of view and could be a valuable alternative during stress tests. This study aimed to illustrate the feasibility of estimating myocardial strain using ultrafast echocardiography combined with a Lagrangian speckle model estimator (LSME) at increased heart rates. Myocardial strain assessment was tested on a dynamic cardiac phantom at heart rates ranging from 60 to 180 beats-per-minute (bpm). Ultrafast echocardiography was obtained with a Verasonics platform equipped with a 2.5 MHz phased array transducer (PRF: 4500 Hz). Negative effects of side lobes and phase delays during the large tilted transmission and compounding of diverging waves were suppressed through a triangle transmit sequence and motion compensation strategy. The robustness and accuracy of affine strain estimation were then enhanced using radiofrequency least-squares-based LSME combined with a coarse-to-fine strain estimation and a time-ensemble estimation strategy. 2D myocardial strain images at systole and early-diastole as well as regional strain curves were estimated. Myocardial strains with high contrast-to-noise and signal-to-noise ratios were obtained at all simulated heart rates. Regional strain curves were accurately estimated and periods matched those of the phantom pump cycles. These preliminary results suggest that the use of ultrafast echocardiography combined with the modified LSME could be useful clinically to provide an accurate and objective method of myocardial strain assessment at high heart rates.
Evaluation of optimal rain gauge network density for rainfall-runoff modelling (2015)

The hydrological significance of the rainfall time-space distribution on a flood hydrograph is well known and assessed in literature. The density of the rain gauge network and the pattern of areal and temporal distribution of rainfall can affect the results of the calibration and the validation of distributed rainfall-runoff modeling. The aim of this work is to assess the implications of changing the composition of rain gauge network, successively reducing the number of gauging stations, while maximizing the performance of the hydrological model. This case study is based on the Mignone river basin (500 km2), which is located in Central Italy and equipped with 4 rain gauges.
A new method to estimate parameters of linear compartmental models using artificial neural networks (1998)

At present, the preferred tool for parameter estimation in compartmental analysis is an iterative procedure; weighted nonlinear regression. For a large number of applications, observed data can be fitted to sums of exponentials whose parameters are directly related to the rate constants/coefficients of the compartmental models. Since weighted nonlinear regression often has to be repeated for many different data sets, the process of fitting data from compartmental systems can be very time consuming. Furthermore the minimization routine often converges to a local (as opposed to global) minimum. In this paper, we examine the possibility of using artificial neural networks instead of weighted nonlinear regression in order to estimate model parameters. We train simple feed-forward neural networks to produce as outputs the parameter values of a given model when kinetic data are fed to the networks' input layer. The artificial neural networks produce unbiased estimates and are orders of magnitude faster than regression algorithms. At noise levels typical of many real applications, the neural networks are found to produce lower variance estimates than weighted nonlinear regression in the estimation of parameters from mono- and biexponential models. These results are primarily due to the inability of weighted nonlinear regression to converge. These results establish that artificial neural networks are powerful tools for estimating parameters for simple compartmental models.

Measurement of the charge asymmetry in highly boosted top-quark pair production in s=8 TeV pp collision data collected by the ATLAS experiment (2016)

In the pp →t¯tprocess the angular distributions of top and anti-top quarks are expected to present a subtle difference, which could be enhanced by processes not included in the Standard Model.
