V-band (57–66 GHz) planar antennas for WPAN applications (2011)

In this paper we present two planar V-band antennas for wireless personal area networks applications. Both of them are implemented on conventional single layer substrates that can serve as packaging for integrated transceivers. Antennas on low- and high-permittivity substrate are investigated and their performances are discussed. The antenna on low-permittivity substrate is shown to have gain higher than 10 dBi and return loss better than 10 dB in 57–66GHz frequency band. The other antenna is demonstrated to have similar characteristics only in two sub-bands of the frequency range due to poor manufacturing quality and higher order mode excitation.

Multiscale Morphological Analysis of the Atherosclerotic Carotid Plaque (2005)

The aim of this paper was to investigate the usefulness of multiscale morphological analysis in the assessment of atherosclerotic carotid plagues. Ultrasound images were recorded from 137 asymptomatic and 137 symptomatic plaques and were converted to binary images at low, middle and high intensity intervals based on structural morphology. Low images represent low intensity regions corresponding to blood, thrombus, lipid or hemorrhage, whereas high images describe the collagen and calcified components of the plaque. Middle image describe image regions that fall between low and high components. The morphological pattern spectra were computed and several classifiers like the K-Nearest Neighbor (KNN), the Probabilistic Neural Network (PNN), and the Support Vector Machine (SVM) were evaluated for classifying these spectra into two classes: asymptomatic or symptomatic. The highest diagnostic yield achieved was 67% that is slightly lower than texture analysis carried out on the same data set.
Power assignment in CDMA personal communication systems with integrated voice/data traffic (2002)

A CDMA personal communication system with integrated voice/data traffic is considered, in which the link transmission error performance is controlled to meet the error rate requirement by the voice user, and the much more stringent error rate requirement for data user is further ensured by ARQ. Optimum power assignment between voice and data users is investigated to maximize the total system throughput. A graphical method is described to obtain this optimum power ratio. Numerical results and a design example are given for a power controlled wideband IS-95 type wireless personal communication system.

A prospective evaluation of degranulation assays in the rapid diagnosis of familial hemophagocytic syndromes (2012)

Familial hemophagocytic lymphohistiocytosis (FHL) is a life-threatening disorder of immune regulation caused by defects in lymphocyte cytotoxicity. Rapid differentiation of primary, genetic forms from secondary forms of hemophagocytic lymphohistiocytosis (HLH) is crucial for treatment decisions. We prospectively evaluated the performance of degranulation assays based on surface up-regulation of CD107a on natural killer (NK) cells and cytotoxic T lymphocytes in a cohort of 494 patients referred for evaluation for suspected HLH. Seventy-five of 77 patients (97%) with FHL3-5 and 11 of 13 patients (85%) with Griscelli syndrome type 2 or Chediak-Higashi syndrome had abnormal resting NK-cell degranulation. In contrast, NK-cell degranulation was normal in 14 of 16 patients (88%) with X-linked lymphoproliferative disease and in 8 of 14 patients (57%) with FHL2, who were identified by diminished intracellular SLAM-associated protein (SAP), X-linked inhibitor of apoptosis protein (XIAP), and perforin expression, respectively. Among 66 patients with a clinical diagnosis of secondary HLH, 13 of 59 (22%) had abnormal resting NK-cell degranulation, whereas 0 of 43 had abnormal degranulation using IL-2-activated NK cells. Active disease or immunosuppressive therapy did not impair the assay performance. Overall, resting NK-cell degranulation below 5% provided a 96% sensitivity for a genetic degranulation disorder and a specificity of 88%. Therefore, degranulation assays allow a rapid and reliable classification of patients, benefiting treatment decisions.

Computing Unique Information for Poisson and Multinomial Systems (2023)

Bivariate Partial Information Decomposition (PID) describes how the mutual information between a random variable M and two random variables Y and Z is decomposed into unique, redundant, and synergistic terms. Recently, PID has shown promise as an emerging tool to understand biological systems and biases in machine learning. However, computing PID is a challenging problem as it typically involves optimizing over distributions. In this work, we study the problem of computing PID in two systems: the Poisson system inspired by the 'ideal Poisson channel' and the multinomial system inspired by multinomial thinning, for a scalar M. We provide sufficient conditions for both systems under which closed-form expressions for many operationally-motivated PID can be obtained, thereby allowing us to easily compute PID for these systems. Our proof consists of showing that one of the unique information terms is zero, which allows the remaining unique, redundant, and synergistic terms to be easily computed using only the marginal and the joint mutual information.
Strictly nonblocking 512/spl times/512 optical fiber matrix switch based on three-stage Clos network (1994)

This letter describes a novel structure for large-matrix connector-type optical switches. The dimensions of the apparatus designed for 512/spl times/512 switching were 0.8 m/sup W//spl times/0.6 m/sup D//spl times/1.85 m/sup H/. It is based on the three-stage Clos network. Switching is accomplished by the mechanical reconnection of fibers. The fiber tangling is avoided by using an intelligent zigzag transfer method for the connector plugs. The mean insertion loss is less than 1 dB for SM fibers. The most appropriate internal fiber link is chosen by a computer algorithm from all possible candidates. The mean switching time is estimated at about 1 min.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Impaired Set-Shifting from Dorsal Stream Disconnection: Insights from a European Series of Right Parietal Lower-Grade Glioma Resection (2021)

Awake surgery with cognitive monitoring has increasingly been implemented to preserve brain networks and functionality. More recently, not only surgery in the left but also in the right hemisphere, i.c., the parietal lobe, was associated with potential risk for deficits in cognitive functions, such as cognitive flexibility. In this explorative pilot study, we compare cognitive performance more than three months after surgery with baseline measurements and explore the association between cognitive decline and subcortical tracts that may have been severed during surgery in the right hemisphere. Twenty-two patients who underwent surgery for a right parietal low-grade glioma were assessed pre- and postoperatively using the Trail Making Test and the Stroop task to administer set-shifting abilities and inhibition. Volume measurements and lesion-symptom mapping analyses were performed on postoperative MRI scans. Careful interpretation of the results shows a change in TMT performance and not on the Stroop Task when the lateral part of the arcuate fasciculus is damaged, indicating that disconnection of the lateral part of the dorsal stream might be correlated specifically with impaired set-shifting and not with inhibition. More importantly, this study underlines the need for international concertation to allow larger studies to increase power and perform more detailed analyses.
Design, Synthesis, and Pharmacological Effects of a Cyclization-Activated Steroid Prodrug for Colon Targeting in Inflammatory Bowel Disease (2009)

Glucocorticoids are used in the treatment of inflammatory bowel disease. A limitation to their use is that they undergo absorption from the GIT before reaching the colon causing severe systemic side effects. We report here on a novel prodrug approach to targeting corticosteroids to the colon. The design involves attaching a 21-ester group that suppresses absorption during transit to the colon. The prodrug is designed to be primed by colonic microflora liberating an amino ester that cyclizes releasing the steroid. One of the prodrugs 5b was as efficacious as prednisolone in the murine DSS model but did not cause thymic atrophy, a marker for systemic steroid effects.
Cardiometabolic genomics and pharmacogenomics investigations in Filipino Americans: Steps towards precision health and reducing health disparities (2022)

At the time of this publication, the study has enrolled 97 participants. This ongoing study is expected to inform future research to reduce cardiovascular health disparities among FAs.
Synthesis, Photophysical and Electronic Properties of New Red‐to‐NIR Emitting Donor–Acceptor Pyrene Derivatives (2019)

We synthesized new pyrene derivatives with strong bis(para-methoxyphenyl)amine donors at the 2,7-positions and n-azaacene acceptors at the K-region of pyrene. The compounds possess a strong intramolecular charge transfer, leading to unusual properties such as emission in the red to NIR region (700 nm), which has not been reported before for monomeric pyrenes. Detailed photophysical studies reveal very long intrinsic lifetimes of >100 ns for the new compounds, which is typical for 2,7-substituted pyrenes but not for K-region substituted pyrenes. The incorporation of strong donors and acceptors leads to very low reduction and oxidation potentials, and spectroelectrochemical studies show that the compounds are on the borderline between localized Robin-Day class-II and delocalized Robin-Day class-III species.
Sarcina ventriculi as the potential cause of abomasal bloat (1999)

Sarcina-like bacteria, possibly Sarcina ventriculi, have been seen upon histopathologic examination of the abomasums of calves that died of abomasal bloat. The ability of the organism to grow at a low pH and produce large amounts of gas suggests that it may be the cause of abomasal bloat.
Agglomeration and percolation conductivity (2001)

We report on results of agglomeration experiments for the Ag/SiO2/Si(100) system. Thin silver films, 100 nm in thickness, were annealed, and their electrical resistance was continuously monitored using a four-point probe technique. Scanning electron microscopy and digital image analysis were used to correlate the time-dependent agglomeration morphology to the sheet resistance of the Ag thin film. Our results indicated that the area fraction of the surface uncovered during agglomeration scaled linearly in time. We found that at fixed annealing temperature, the normalized sheet resistance followed power-law scaling in time, i.e., R∼|t−τ|−μ, (μ=1.25±0.1) where τ corresponds to the time it takes to reach electrical failure of the sample.
Demonstration of Highly Linear Uncooled DFB Lasers for Next Generation RF over Fibre Applications (2002)

Growing the impact of management education and scholarship (2022)

Management is only taught in business schools. For more than 100 years it has also been taught by a special type of university that is ‘more than a business school’. An international group of university leaders trace the emergence, role and future contributions of ‘universities for business and management’ ome traditions remain vital while others are fading. Performing traditional and modern opera pieces at large concert venues, this pluralistic approach expanded popular appreciation of great composers, such as Wagner and Bizet. Just like opera, management education needs to balance tradition and innovation. Clearly, it is transforming its delivery and learning techniques to embrace new possibilities offered by technology and digitalisation. Few institutions continually experiment with preparing students for innovation, entrepreneurial thinking or navigating a business environment set in a global world that is culturally diverse, yet highly connected. Managers cannot ignore the deep philosophical undercurrents running through the history of mankind and across cultures.
Arthrodesis of the Knee with a Long Intramedullary Nail Following the Failure of a Total Knee Arthroplasty as the Result of Infection (2007)

We believe that obtaining large surfaces of bleeding contact bone during arthrodesis following staged treatment of an infection at the site of a failed total knee arthroplasty contributes to stability and enhances bone-healing. Staged arthrodesis with use of a long intramedullary nail and convex-to-concave preparation of bone ends provided a painless functional gait with low complication and reoperation rates in this challenging group of patients.
Analysis of Proteins, Protein Complexes, and Organellar Proteomes Using Sheathless Capillary Zone Electrophoresis - Native Mass Spectrometry (2017)

Native mass spectrometry (MS) is a rapidly advancing field in the analysis of proteins, protein complexes, and macromolecular species of various types. The majority of native MS experiments reported to-date has been conducted using direct infusion of purified analytes into a mass spectrometer. In this study, capillary zone electrophoresis (CZE) was coupled online to Orbitrap mass spectrometers using a commercial sheathless interface to enable high-performance separation, identification, and structural characterization of limited amounts of purified proteins and protein complexes, the latter with preserved non-covalent associations under native conditions. The performance of both bare-fused silica and polyacrylamide-coated capillaries was assessed using mixtures of protein standards known to form non-covalent protein-protein and protein-ligand complexes. High-efficiency separation of native complexes is demonstrated using both capillary types, while the polyacrylamide neutral-coated capillary showed better reproducibility and higher efficiency for more complex samples. The platform was then evaluated for the determination of monoclonal antibody aggregation and for analysis of proteomes of limited complexity using a ribosomal isolate from E. coli. Native CZE-MS, using accurate single stage and tandem-MS measurements, enabled identification of proteoforms and non-covalent complexes at femtomole levels. This study demonstrates that native CZE-MS can serve as an orthogonal and complementary technique to conventional native MS methodologies with the advantages of low sample consumption, minimal sample processing and losses, and high throughput and sensitivity. This study presents a novel platform for analysis of ribosomes and other macromolecular complexes and organelles, with the potential for discovery of novel structural features defining cellular phenotypes (e.g., specialized ribosomes).

Estimation techniques in non-stationary renewal processes (1980)

The multiplicative intensity model for the intensity function u(t;N(t);w) = v(t)r(t - of a self-exciting point process is analyzed in terms of the distortion of v(t) by the channel r(x). A convenient and common method of presenting point process data, the Post Stimulus Histogram is shown to be related to the ensemble average of the intensity process and hence incorporates stimulus v() as well as refractory r() related effects. This quantity is not usually amenable to closed-form representation. We propose an approximation to the PST which is reasonably good under specified conditions. A maximum likelihood estimator of r(x), where v(t) is known, is derived. A maximum likelihood estimator of v(t), given r(x), is also derived. This estimator is meaningful only when the signal v(t) is known to be periodic. The M.L. Estimator compensates for relative dead-time effects. We propose an iterative dead-time processor, which operating on the histogram obtained from the M.L. Estimate, partially compensates for absolute dead-time effects. The performance of these estimators is compared with those of other procedures. Applications to spike trains recorded from auditory neurons are discussed.
Biogenerated Polymers: An Enviromental Alternative (2020)

Biogenerated polymers are of great interest in industry in general, due to the trend of reduced use of petroleum-derived materials. However, their development costs are high and the benefit is still low. Currently, biodegradable alternatives are available from biogenerated polymers approximately 10% of the plastics market. Its consumption is estimated at 50,000 tons/year in Europe, with a share of less than 1%. In this order of ideas, the objective of this revision is to show the importance of the production of biogenerated polymers in the manufacture of biodegradable materials, from their formulation that contains macromolecules of natural origin such as oligomers or monomers. To this purpose, we will discuss topics related to several types of biogenerated polymers, such as chitosan, starch, polybutylene succyanate and polylactic acid, which have been used for the development of biogenerated polymeric materials by different research groups.
Energy awareness in self-growing sensor networks (2012)

An ever increasing variety of applications are being addressed by wireless sensor networks, resulting in a continuous proliferation of their deployments, which are in many cases co-located. This development is mostly hindered by the operational complexity involved with management and maintenance of large numbers of small, battery powered wireless sensor devices. The paradigm of energy aware self-growing networks addresses these difficulties. It focuses on power saving which reduces the major maintenance complexity of replacing batteries, and on automatic cooperation between networks which reduces the management complexity. However, cross-network cooperation requires cross-network communication, which is not straightforward as they typically operate on different frequencies. Receiver Directed Transmission is a MAC layer protocol which can bridge this gap, while also minimizing interference and thus reducing the number of transmissions. In this work we study how Receiver Directed Transmission can be combined with Low Power Listening in order to take advantage of the reduced number of transmissions to improve power consumption. We then implement the selected approach on TinyOS and verify its operation experimentally.
EFFECT OF ESSENTIAL OILS ON THE ROOT-KNOT NEMATODE MANAGEMENT (2017)

In an attempt to find alternative compounds for the management of root-knot nematodes, whether essential oils would be absorbed by plants and affect the development of Meloidogyne javanica inside tomato roots was evaluated. First, the viability, in vitro, of the essential oils of Artemisia absinthium (wormwood), Mentha × piperita (peppermint), Origanum vulgare (oregano) and Thymus vulgaris (thyme) was assessed. Then, the same essential oils were tested in pot experiments, at concentrations of 0.25% (v / v) and 0.5% (v / v). In in vitro tests, all essential oils were effective in killing the juveniles, resulting in mortality rates of 99.0% at both concentrations. The essential oils of Mentha × piperita, O. vulgare and T. vulgaris were effective in reducing nematode hatching to about 2.0%. In tests conducted under greenhouse conditions, however, tomato plants treated with the essential oils of A. absinthium, Mentha × piperita and O. vulgare hadincreased the number of M. javanica eggs and galls. Therefore, despite being highly toxic to nematodes in vitro, some of the essential oils tested in this study increased nematode development.
Translational Mini-Review Series on Vaccines for HIV: T lymphocyte trafficking and vaccine-elicited mucosal immunity (2009)

Many pathogens use mucosal surfaces to enter and propagate within the host, making particularly desirable vaccines that target immune responses specifically to mucosal compartments. The majority of mucosal vaccine design strategies to date have been empirical in nature. However, an emerging body of basic immunological knowledge is providing new insights into the regulation of tissue-specific lymphocyte trafficking and differentiation. These insights afford the opportunity for the rational design of vaccines that focus immune responses at mucosal surfaces. Mucosal cellular immunity may prove critical for protection in the context of HIV infection, and thus there has been considerable interest in developing vaccines that target HIV-specific cellular immune responses to the gastrointestinal and vaginal mucosa. However, the optimal strategies for eliciting mucosal cellular immune responses through vaccination remain to be determined. Here, we review both recent vaccine studies and emerging paradigms from the basic immunological literature that are relevant to the elicitation of potent and protective mucosal cellular immune memory. Increasing the synergy between these avenues of research may afford new opportunities for mucosal vaccine design.
