Concurrent dual-band GaN-HEMT power amplifier at 1.8 GHz and 2.4 GHz (2012)

This paper presents the design, implementation, and experimental results of a highly efficient concurrent dual-band GaN-HEMT power amplifier at 1.8 GHz and 2.4 GHz. A bare-die approach, in conjunction with a harmonic source-pull/load-pull simulation approach, are used in order to design and implement the harmonically tuned dual-band PA. For a continuous wave output power of 42.3 dBm the measured gain is 12 dB in the two frequency bands; while the power added efficiency is 64% in both bands. Linearized modulated measurements, using concurrently 10 MHz LTE and WiMAX signals, show an average PAE of 25% and and adjacent channel leakage ratio of -48 dBc and -47 dBc at 1.8 GHz and 2.4 GHz, respectively.
P347Epicardial-derived interstitial fibroblasts and bone marrow-derived cell interaction determines post-infarction ventricular remodeling (2014)

Myocardial infarction is a prevalent cardiovascular disease. Mechanisms of repair in the post-infarcted heart include a progressive fibrosis that severely affects cardiac performance, eventually leading to cardiac failure. Cardiac fibrosis in the context of ventricular remodeling after infarction depends on fibroblasts of the cardiac interstitium (cardiac fibroblasts), a heterogeneous population of cells which, upon interaction with other interstitial cell types, initiates a massive deposition of extracellular matrix promoting the formation of a characteristic scar. In this work we have studied the cellular components of the cardiac interstitium from the embryo to the adult. Our results show that Wilms tumor supresor (Wt1) positive epicardial-derived mesenchymal cells pioneer the formation of the cardiac interstitium along embryogenesis, followed by the peri- and post-natal incorporation of bone-marrow derived cells. Adult epicardial-derived cells robustly differentiate into cardiac fibroblasts under normal and pathologic conditions, and become the predominant fibroblast type in the post-infarction scar. Furthermore, epicardial-derived cardiac fibroblasts are shown to display stromal properties respect to bone marrow-derived cells, critically contributing to the homing and persistence of circulating cells after infarction.
Joint Opportunistic Scheduling and Selective Channel Feedback (2013)

It is well known that Max-Weight type scheduling algorithms are throughput optimal since they achieve the maximum throughput while maintaining the network stability. However, the majority of existing works employing Max-Weight algorithm require the complete channel state information (CSI) at the scheduler without taking into account the associated overhead. In this work, we design a Scheduling and Selective Feedback algorithm (SSF) taking into account the overhead due to acquisition of CSI. SSF algorithm collects CSI from only those users with sufficiently good channel quality so that it always schedules the user with the highest queue backlog and channel rate product at every slot. We characterize the achievable rate region of SSF algorithm by showing that SSF supports 1 + ϵ fraction of the rate region when CSI from all users are collected. We also show that the value of ϵ depends on the expected number of users which do not send back their CSI to the base station. For homogenous and heterogeneous channel conditions, we determine the minimum number of users that must be present in the network so that the rate region is expanded, i.e., ϵ > 0. We also demonstrate numerically in a realistic simulation setting that this rate region can be achieved by collecting CSI from only less than 50% of all users in a CDMA based cellular network utilizing high data rate (HDR) protocol.

Molecular Targets for PET Imaging of Activated Microglia: The Current Situation and Future Expectations (2017)

Microglia, as cellular mediators of neuroinflammation, are implicated in the pathogenesis of a wide range of neurodegenerative diseases. Positron emission tomography (PET) imaging of microglia has matured over the last 20 years, through the development of radiopharmaceuticals targeting several molecular biomarkers of microglial activation and, among these, mainly the translocator protein-18 kDa (TSPO). Nevertheless, current limitations of TSPO as a PET microglial biomarker exist, such as low brain density, even in a neurodegenerative setting, expression by other cells than the microglia (astrocytes, peripheral macrophages in the case of blood brain barrier breakdown), genetic polymorphism, inducing a variation for most of TSPO PET radiopharmaceuticals' binding affinity, or similar expression in activated microglia regardless of its polarization (pro- or anti-inflammatory state), and these limitations narrow its potential interest. We overview alternative molecular targets, for which dedicated radiopharmaceuticals have been proposed, including receptors (purinergic receptors P2X7, cannabinoid receptors, α7 and α4β2 nicotinic acetylcholine receptors, adenosine 2A receptor, folate receptor β) and enzymes (cyclooxygenase, nitric oxide synthase, matrix metalloproteinase, β-glucuronidase, and enzymes of the kynurenine pathway), with a particular focus on their respective contribution for the understanding of microglial involvement in neurodegenerative diseases. We discuss opportunities for these potential molecular targets for PET imaging regarding their selectivity for microglia expression and polarization, in relation to the mechanisms by which microglia actively participate in both toxic and neuroprotective actions in brain diseases, and then take into account current clinicians' expectations.
Comparing discrimination and CFA for selecting tracking features (2008)

The ability of a tracker to isolate the foreground target from the background of an image is crucially dependent on the set of features selected for tracking. Collins & Liu [2] propose an on-line, adaptive approach to selecting the set of features based on the insight that the set of features that best discriminate between target and background classes is the best set to use for tracking. In previous work [10], we have proposed an approach based on Combinatorial Fusion Analysis for selecting features for Real-Time tracking. We discuss the relative merits of the two methods and motivate their combination to produce an improved tracking system. We show several results from a difficult tracking sequence with human targets to demonstrate the effectiveness of the combined system.
Exome Sequencing Identifies Mutations in CCDC114 as a Cause of Primary Ciliary Dyskinesia (2021)

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous, autosomal-recessive disorder, characterized by oto-sino-pulmonary disease and situs abnormalities. PCD-causing mutations have been identified in 14 genes, but they collectively account for only ∼60% of all PCD. To identify mutations that cause PCD, we performed exome sequencing on six unrelated probands with ciliary outer dynein arm (ODA) defects. Mutations in CCDC114, an ortholog of the Chlamydomonas reinhardtii motility gene DCC2, were identified in a family with two affected siblings. Sanger sequencing of 67 additional individuals with PCD with ODA defects from 58 families revealed CCDC114 mutations in 4 individuals in 3 families. All 6 individuals with CCDC114 mutations had characteristic oto-sino-pulmonary disease, but none had situs abnormalities. In the remaining 5 individuals with PCD who underwent exome sequencing, we identified mutations in two genes (DNAI2, DNAH5) known to cause PCD, including an Ashkenazi Jewish founder mutation in DNAI2. These results revealed that mutations in CCDC114 are a cause of ciliary dysmotility and PCD and further demonstrate the utility of exome sequencing to identify genetic causes in heterogeneous recessive disorders.
Regional and age differences in specialised palliative care for patients with pancreatic cancer (2021)

From 2011 to 2018 more patients with pancreatic cancer than previously were admitted to SPC, with marked differences between regions of residence and age groups. The persistently short period of time the patients are in SPC raises concern that early integrated palliative care is not fully integrated into the Danish healthcare system for patients with pancreatic cancer, with the risk that the referral comes so late that the patients do not receive the full benefit of the SPC.

Surface Matching and Change Detection Using a Modified Hough Transformation for Robust Parameter Estimation (2001)

Many photogrammetric and GIS applications, such as city modelling, change detection and object recognition, deal with surfaces. Change detection involves looking for differences between two surface models that are obtained from different sensors, for example an optical sensor and a laser scanner, or by the same sensor at different epochs. Surfaces obtained through a sampling process may also have to be compared for future processing (for example transformation parameter estimation and change detection). Surface matching is therefore an essential task in these applications. The matching of surfaces involves two steps. The first step deals with finding the correspondences between two surface points and/or patches. The second step requires the determination of transformation parameters between the two surfaces. However, since most surfaces consist of randomly distributed discrete points and may have different reference systems, finding the correspondences cannot be achieved without knowing the transformation parameters between the two surfaces. Conversely, deriving the transformation parameters requires the knowledge of the correspondence between the two point sets. The suggested approach for surface matching deals with randomly distributed data sets without the need for error prone interpolation and requires no point‐to‐point correspondence between the two surfaces under consideration. This research simultaneously solves for the correspondence and the transformation parameters using a Modified Iterated Hough Transform for robust parameter estimation. Several experiments are conducted to prove the feasibility and the robustness of the suggested approach, even when a high percentage of change exists.
Effect of geopolymer paste on compressive strength, water absorption and porosity (2020)

This paper presents the effect of geopolymer paste on the compressive strength, water absorption and porosity. Fly ash is a waste materials produced by combustion of coal at power plant. Fly ash were mixed with alkaline activators that are sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solutions. The alkaline activator was prepared 24 hours prior to use with the ratio of the mixture of NaOH/Na2SiO3 is 2.5 to 1. The mixture are placed in cylinder mould, compacted and kept in the mould for 24 hours until it hardened and and cured at 60 °C in the oven for 24 hours. The sample were then left for 7, 14 and 28 days before it be tested. It was observed that the fly ash geopolymer paste sample had a optimum results. The compressive strength value for 28 days was 53.92 MPa and the value of water absorption were 0.003 % and porosity were 1.829 %. The pore size decreases and the structures became denser. The porosity and permeability also decreased hence the strength potentially improved.

Permanent electrochemical promotion of C3H8 oxidation over thin sputtered Pt films (2010)

The effect of “permanent electrochemical promotion of catalysis” (P-EPOC) was studied for the first time in the catalytic deep oxidation of C3H8 over a thin (∼ 150 nm) sputtered Pt film on YSZ, under excess of oxygen at 350 °C. Short positive potential application (+ 1 V) resulted in a 5.6-fold increase of the catalytic rate, where C3H8 conversion reached 33%, while the apparent Faradaic efficiency was ∼ 330. After positive current interruption the catalytic rate remained in a highly active steady-state, determined by the total charge of the anodic polarization step. Restoration of the catalytic activity to the initial value occurred only by a similar negative potential imposition. This new stable steady-state after current interruption can be interpreted by storage of a non-reactive oxygen species upon anodic polarization at the proximity of the Pt/YSZ interface and subsequent enhanced migration of spillover Oδ− species from the electrolyte support to the Pt/gas interface under open-circuit conditions.
Lyophilization of Protein Pharmaceuticals (2020)

This chapter outlines the main principles that are important, at least as a starting point for guiding the development of stable lyophilized protein products, there will not be an exhaustive review of all of the published studies, many of which are excellent, on acute and storage stability of lyophilized proteins. It provides an overview of the principles that must be followed, and how essential physical data are obtained and used to meet these criteria. The efficient and consistent production of a stable, freeze-dried, protein product, contained in a mechanically strong and rapidly dissolvable cake, is the ultimate objective during the development of a freeze-drying cycle. A precaution for this single-step drying cycle is that some products may collapse during the transition from primary drying to secondary drying, if the temperature gradient between the shelf and sample at the end of primary drying is too great, resulting in an excessively fast warming rate.

Development and Validation of a Fully GMP-Compliant Process for Manufacturing Stromal Vascular Fraction: A Cost-Effective Alternative to Automated Methods (2020)

The therapeutic use of adipose-derived stromal vascular fraction (SVF) is expanding in multiple pathologies. Various processes have been proposed for manufacturing SVF but they must be revisited based on advanced therapy medicinal product (ATMP) regulations. We report here the development and validation of a fully good manufacturing practices (GMP)-compliant protocol for the isolation of SVF. Adipose tissue was collected from healthy volunteers undergoing lipoaspiration. The optimal conditions of collagenase digestion and washing were determined based on measurements of SVF cell viability, yield recovery, and cell subset distribution. Comparability of the SVF obtained using the newly developed manufacturing process (n = 6) and the Celution-based automated method (n = 33), used as a reference, was established using inter-donor analyses. Characteristics of SVF (n = 5) generated using both manufacturing protocols were analyzed for an intra-donor comparison. In addition, these comparisons also included the determination of colony-forming unit fibroblast frequency, in vitro angiogenic activity, and in vivo regenerative effects in a mouse ischemic cutaneous wound model. We successfully developed a process for the generation of SVF presenting higher cell viability and yield recovery compared to the Celution device-based protocol. Characteristics of the SVF including phenotype, capacity for angiogenesis, and wound-healing promotion attested to the comparability of the two manufacturing processes. We validated an optimized non-automated process that should allow for a GMP-compliant, more affordable, and reduced-cost strategy to exploit the potential of SVF-based regenerative therapies.

The Oblique Rectus Abdominal Myocutaneous Flap for Complex Pelvic Wound Reconstruction (2008)

The treatment of complex pelvic wounds, especially following pelvic radiation, is facilitated by the oblique rectus abdominal myocutaneous flap. This technique provides ample tissue for large pelvic wounds, including skin for perineal defects. Comparing our results to existing literature, the oblique rectus abdominal myocutaneous flap displays a favorable morbidity profile, providing a safe means of delivering well-vascularized tissue to the pelvic cavity and perineal floor.
Egg albumin microspheres containing paracetamol for oral administration. I. In vitro characterization (1990)

Different egg albumin microsphere systems for oral administration of paracetamol were prepared by the emulsion and capillary extrusion methods. The size of the microspheres depended on the method used to produce the microcapsules and also the size of the crystals of paracetamol. The effect of the following factors on in vitro dissolution were studied: different denaturation processes, variation in the ratio of paracetamol to albumin, size of microspheres, remnant oil in the microspheres, and the coating of the microspheres with membranes of polymethacrylates (Eudragit). The most important factors to control the release of paracetamol from the microspheres were the denaturation process and the use of waxes and membranes to delay the release of paracetamol from the microspheres. The egg albumin microspheres were very porous and permeable to water and thus the release of the paracetamol from the matrix was usually fast unless the microspheres were suitably coated, with, for example, Eudragit RL or RS.
5‐Hydroxymethylfurfural‐Based Adhesives (2023)

5-Hydroxymethylfurfural (5-HMF) is often referred to as a “sleeping giant”. The term highlights not only the great potential of 5-HMF but also points to the many challenges still preventing its large-scale production. This chapter gives an overview of 5-HMF-based adhesives, focusing on the challenges and the opportunities for 5-HMF, e.g., in terms of its industrial production, the availability of feedstocks, and the most promising derivatives for adhesive applications. 5-HMF shows high potential as a component in adhesive systems. The industrial production is still in its very early stages, which makes in situ approaches for 5-HMF utilization an important possible alternative. Although most of the adhesive systems reported so far were applied under conditions far from, e.g., today's wood composite board production, at least some of the adhesives are used under conditions similar to present fossil-based adhesive systems considering the current industrial production standards.
Production of Biodiesel at Kinetic Limit Achieved in a Centrifugal Reactor/Separator (2010)

The kinetics of the transesterification of soybean oil has been investigated in a centrifugal reactor at temperatures from 45 to 80 C and pressures up to 2.6 bar using gas chromatography flame ionization detection (GC-FID) and infrared (IR) spectroscopy. The yields of product methyl esters were quantified using IR, proton Nuclear Magnetic Resonance (H1NMR), and viscosity measurements and were found to achieve 90% of the yield in 2 min; however, to meet ASTM specifications with one pass through the reactor, a 15 min residence time was needed. Performance was improved by sequential reactions, allowing separation of by-product glycerine and injection of additional small aliquots of methanol. The kinetics was modeled using a three-step mechanism of reversible reactions, which was used to predict performance at commercial scale. The mechanism correctly predicted the exponential decline in reaction rate as the concentration of the products allowed significant reverse reactions to occur.
Acoustic Vehicle Speed Estimation From Single Sensor Measurements (2021)

The paper addresses acoustic vehicle speed estimation using single sensor measurements. We introduce a new speed-dependent feature based on the attenuation of the sound amplitude. The feature is predicted from the audio signal and used as input to a regression model for speed estimation. For this research, we have collected, annotated, and published a dataset of audio-video recordings of single vehicles passing by the camera at a known constant speed. The dataset contains 304 urban-environment real-field recordings of ten different vehicles. The proposed method is trained and tested on the collected dataset. Experiments show that it is able to accurately predict the pass-by instant of a vehicle and to estimate its speed with an average error of 7.39 km/h. When the speed is discretized into intervals of 10 km/h, the proposed method achieves the average accuracy of 53.2% for correct interval prediction and 93.4% when misclassification of one interval is allowed. Experiments also show that sound disturbances, such as wind, severely affect acoustic speed estimation.
