User Scheduling and Power Allocation for Precoded Multi-Beam High Throughput Satellite Systems With Individual Quality of Service Constraints (2022)

For extensive coverage areas, multi-beam high throughput satellite (HTS) communication is a promising technology that plays a crucial role in delivering broadband services to many users with diverse Quality of Service (QoS) requirements. This article focuses on multi-beam HTS systems where all beams reuse the same spectrum. In particular, we propose a novel user scheduling and power allocation design capable of providing guarantees in terms of the individual QoS requirements while maximizing the system throughput under a limited power budget. Precoding is employed in the forward link to mitigate mutual interference among the users in multiple-access scenarios over different coherence time intervals. The combinatorial optimization structure from user scheduling requires an extremely high cost to obtain the global optimum even when a reduced number of users fit into a time slot. Therefore, we propose a heuristic algorithm yielding a good trade-off between performance and computational complexity, applicable to a static operation framework of geostationary (GEO) satellite networks. Although the power allocation optimization is signomial programming, non-convex on a standard form, the solution can be lower bounded by the global optimum of a geometric program with a hidden convex structure. A local solution to the joint user scheduling and power allocation problem is consequently obtained by a successive optimization approach. Numerical results demonstrate the effectiveness of our algorithms on GEO satellite networks by providing better QoS satisfaction combined with outstanding overall system throughput.
Association of Polymorphism in the Promoter Region of the Apolipoprotein E Gene with Diastolic Blood Pressure in Normotensive Japanese. (2000)

The epsilon4 allele of apolipoprotein E (APOE) is reported to be a genetic risk factor of atherosclerosis through hyperlipidemia and late-onset Alzheimer's dementia. A recent report showed that a genetic variant (A -491T) in the promoter region of the APOE gene increases the risk of Alzheimer's disease. In the present study, we examined whether these APOE polymorphisms were genetically involved in essential hypertension. Japanese hypertensives (n=180) with a family history of hypertension and normotensive controls (n=195, sex and age matched with hypertensives) were recruited from the outpatients of Osaka University Hospital, and an informed consent to participate in the study was obtained from each person. APOE polymorphisms were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The frequencies of the A -491 allele in hypertensives and normotensives were 0.98 and 0.97, respectively, and the TT/-491 genotype was not found in either group. No significant differences between hypertensives and normotensives were observed in allele frequencies in either APOE polymorphism; however, the mean diastolic blood pressure in normotensive subjects with AA/-491 was significantly higher than in the subjects with AT/-491 (p < 0.01). These results suggest that the presence of the APOE promoter polymorphism is not a major risk factor for hypertension but that it does have some minor effect on basal blood pressure variation.
Measurement of the CKM angle γ from a combination of B±→Dh± analyses (2013)

A combination of three LHCb measurements of the CKM angle gamma is presented. The decays B-+/- -&gt; DK +/- and B-+/- -&gt; D pi(+/-) are used, where D denotes an admixture of D-0 and (D) over bar (0) mesons, decaying into K+K-, pi(+)pi(-), K-+/-pi(-/+), K-+/-pi(-/+)pi(+/-)pi(-/+), or K-S(0)pi(+)pi(-) final states. All measurements use a dataset corresponding to 1.0 fb-1 of integrated luminosity. Combining results from B-+/- -&gt; DK +/- Dill decays alone a best-fit value of gamma = 72.0 degrees is found, and confidence intervals are set gamma is an element of [56.4, 86.7]degrees at 68% CL, gamma is an element of [42.6, 99.6]degrees at 95% CL. The best-fit value of gamma found from a combination of results from B-+/- -&gt; D pi(+/-) decays alone, is gamma = 18.9 degrees, and the confidence intervals gamma is an element of [7.4, 99.2]degrees boolean OR [167.9, 176.4]degrees at 68% CL are set, without constraint at 95% CL The combination of results from B1 DKI and B -&gt; DTC decays gives a best-fit value of y = 72.6 degrees and the confidence intervals gamma is an element of [55.4, 82.3]degrees at 68% CL, gamma is an element of [40.2, 92.7]degrees at 95% CL are set. All values are expressed modulo 180 degrees, and are obtained taking into account the effect of D-0-(D) over bar (0) mixing. (C) 2013 CERN. Published by Elsevier B.V. All rights reserved.
Left Ventricular Remodelling After St-Segment Elevation Myocardial Infarction: Sex Differences and Prognosis (2020)

LV post-infarct remodelling incidence, as well as long-term survival of LV remodellers and non-remodellers, was similar in men and women who were treated with primary PCI and optimal pharmacotherapy post-STEMI.
Differential laser absorption and thermal emission for remote identification of opaque surface coatings (1997)

We experimentally and theoretically studied the phenomenon of thermal emission from nonvolatile liquid surface coatings following heating with a pulsed CO(2) laser. The effects of thermal diffusion across the liquid-air and liquid-substrate interfaces as well as the full absorption spectrum of the liquid are addressed theoretically. The differential temporal and intensity characteristics of the thermal emission signal from the heated surface coating, resulting from the differential heat deposition profile for on- and off-resonance excitation, are shown to be useful for the purposes of identifying different surface contaminants. The application of this technique to standoff thermal imaging of contaminated surfaces is discussed.
Synthesis of signal processing structured datapaths for FPGAs supporting RAMs and busses (1995)

A novel approach is presented for transforming a given scheduled and bound signal processing algorithm for a multiplexer based datapath to a BUS/RAM based FPGA datapath. A datapath model is introduced that allows maximum flexibility in scheduling bus transfers independent of operation scheduling. A novel integer linear programming (ILP) formulation that optimally selects and assigns data-transfers to busses while scheduling the bus transfers to minimize a linear combination of the number of busses, bus loading in terms of tristate drivers and fanout, registers and register file storage (RAM) locations. We demonstrate that our resulting optimal datapaths compare favorably to others for signal processing synthesis benchmarks such as: single and multiple elliptic filter and fast discrete-cosine-transform (FDCT).
Event-triggered Feedback Control for Signal Temporal Logic Tasks (2018)

A framework for the event-triggered control synthesis under signal temporal logic (STL) tasks is proposed. In our previous work, a continuous-time feedback control law was designed, using the prescribed performance control technique, to satisfy STL tasks. We replace this continuous-time feedback control law by an event-triggered controller. The event-triggering mechanism is based on a maximum triggering interval and on a norm bound on the difference between the value of the current state and the value of the state at the last triggering instance. Simulations of a multi-agent system quantitatively show the efficacy of using an event-triggered controller to reduce communication and computation efforts.
Time-resolved transmission through homogeneous scattering media: time-response effects (1999)

An analytical expression has been obtained that describes the time variation of time-resolved signals transmitted through or reflected by a homogeneous scattering slab as measured with a detection system having a square-impulse response. This expression can be used to improve the match between theoretical and experimental time-resolved signals measured with a system having a finite response time. It can also be used to assess the effect of a finite detection response time on the time-domain characterization of a turbid medium. The expression can be adapted to detection systems that are not time invariant.
Insulin‐like growth factor‐II is produced by, signals to and is an important survival factor for the mature podocyte in man and mouse (2013)

Podocytes are crucial for preventing the passage of albumin into the urine and, when lost, are associated with the development of albuminuria, renal failure and cardiovascular disease. Podocytes have limited capacity to regenerate, therefore pro-survival mechanisms are critically important. Insulin-like growth factor-II (IGF-II) is a potent survival and growth factor; however, its major function is thought to be in prenatal development, when circulating levels are high. IGF-II has only previously been reported to continue to be expressed in discrete regions of the brain into adulthood in rodents, with systemic levels being undetectable. Using conditionally immortalized human and ex vivo adult mouse cells of the glomerulus, we demonstrated the podocyte to be the major glomerular source and target of IGF-II; it signals to this cell via the IGF-I receptor via the PI3 kinase and MAPK pathways. Functionally, a reduction in IGF signalling causes podocyte cell death in vitro and glomerular disease in vivo in an aged IGF-II transgenic mouse that produces approximately 60% of IGF-II due to a lack of the P2 promoter of this gene. Collectively, this work reveals the fundamental importance of IGF-II in the mature podocyte for glomerular health across mammalian species.
Lipocortin-1 Immunoreactivity in the Normal Human Central Nervous System and Lesions with Astrocytosis (1989)

The authors have examined the cellular distribution of lipocortin-1 (L-1) in the normal and diseased central nervous system (CNS) using the peroxidase-antiperoxidase (PAP) technique with a polyclonal antibody specific for L-1. L-1 immunoreactivity was evaluated in the frontal cortex, parahippocampal gyrus/lateral ventricle, cerebellum, medulla, and spinal cord from 27 normal human fetuses, neonates, and adults without neurologic disease and in these same regions and representative lesions from 35 patients with diseases producing varying degrees of astrocytosis, including intraparenchymal hemorrhage; embolic, thrombotic, or traumatic infarctions; and Alzheimer's disease (AD). L-1 immunoreactivity was identified in ependymocytes, choroid plexus epithelia, and scattered subependymal astrocytes throughout the ventricular system from 15 weeks gestation through 82 years of age in both normal and diseased CNSs. L-1 immunoreactivity was also detected in reactive astrocytes and many macrophages surrounding each infarction regardless of site or pathogenesis and in scattered reactive astrocytes in people with AD or SDAT. The limited distribution of L-1 in CNS is consistent with the low amounts of L-1 found in brain and suggests that L-1 may participate in the normal function of ependymocytes and the pathophysiology of reactive astrocytosis.

Polarity control and transport properties of Mg-doped (0001) InN by plasma-assisted molecular beam epitaxy (2013)

The authors report on the plasma-assisted molecular beam epitaxy growth and carrier transport of Mg-doped In-face (0001) InN. The 1.2 μm thick InN films were grown on GaN:Fe templates under metal rich conditions with Mg concentration from 1 × 1017/cm3 to 3 × 1020/cm3. A morphological transition, associated with the formation of V-shape polarity inversion domains, was observed at Mg concentration over 7 × 1019/cm3 by atomic force microscopy and transmission electron microscopy. Seebeck measurements indicated p-type conductivity for Mg-concentrations from 9 × 1017/cm3 to 7 × 1019/cm3, i.e., as it exceeded the compensating (unintentional) donor concentration.

Reduced Ferrite Double D Pad for Roadway IPT Applications (2020)

Roadway inductive power transfer presents an opportunity to provide a robust and user friendly system for electric vehicle charging by utilizing magnetic couplers (pads) embedded in the roadway. Roadway pads are expected to have a long service life but existing pads use a large quantity of the brittle magnetic material ferrite, which may break in the harsh environment of a roadway. This article shows what happens when the volume of ferrite material is reduced from an example double D pad to minimize the quantity and size of ferrite that needs to be protected. Also presented are design insights into the placement of a reflection winding that helps shape the field in the absence of the majority of ferrite. The final selected example design reduces the leakage magnetic field where a person may be present by 43%, at the expense of an increase in primary VA of 73% from the original double D pad. The final presented pad reduces the ferrite volume by 86% compared to the original example double D pad, is only 50 mm thick, and is shown to have a measured dc-dc efficiency of 91% when delivering 4.7 kW to an available secondary.
Langmuir Analysis of Nanoparticle Polyvalency in DNA‐Mediated Adsorption (2014)

Many nanoparticle adsorption processes are dictated by the collective interactions of surface-bound ligands. These adsorption processes define how nanoparticles interact with biological systems and enable the assembly of nanoparticle-based materials and devices. Herein, we present an approach for quantifying nanoparticle adsorption thermodynamics in a manner that satisfies the assumptions of the Langmuir model. Using this approach, we study the DNA-mediated adsorption of polyvalent anisotropic nanoparticles on surfaces and explore how deviations from model assumptions influence adsorption thermodynamics. Importantly, when combined with a solution-based van't Hoff analysis, we find that polyvalency plays a more important role as the individual interactions become weaker. Furthermore, we find that the free energy of anisotropic nanoparticle adsorption is consistent across multiple shapes and sizes of nanoparticles based on the surface area of the interacting facet.
Mechanistic Understanding of Uranyl Ion Complexation on Montmorillonite Edges: A Combined First-Principles Molecular Dynamics–Surface Complexation Modeling Approach (2018)

Systematic first-principles molecular dynamics (FPMD) simulations were carried out to study the structures, free energies, and acidity constants of UO<sub>2</sub><sup>2+</sup> surface complexes on montmorillonite in order to elucidate the surface complexation mechanisms of the uranyl ion (UO<sub>2</sub><sup>2+</sup>) on clay mineral edges at the atomic scale. Four representative complexing sites were investigated, that is, ≡Al(OH)<sub>2</sub> and ≡AlOHSiO on the (010) surface and ≡AlOHOa and ≡SiOOa on the (110) surface. The results show that uranyl ions form bidentate complexes on these sites. All calculated binding free energies for these complexes are very similar. These bidentate complexes can be hydrolyzed, and their corresponding derived p K<sub>a</sub> values (around 5.0 and 9.0 for p K<sub>a1</sub> and p K<sub>a2</sub>, respectively) indicate that UO<sub>2</sub>(OH)<sup>+</sup> and UO<sub>2</sub>(OH)<sub>2</sub> surface groups are the dominant surface species in the environmental pH range. The OH groups of UO<sub>2</sub>(OH)<sub>2</sub> surface complexes can act as complexing sites for subsequent metals. Additional simulations showed that such multinuclear adsorption is feasible and can be important at high pH. Furthermore, FPMD simulation results served as input parameters for an electrostatic thermodynamic surface complexation model (SCM) that adequately reproduced adsorption data from the literature. Overall, this study provides an improved understanding of UO<sub>2</sub><sup>2+</sup> complexation on clay mineral edge surfaces.
Resistance and repression in India: the hunger strike at the Andaman cellular jail in 1933 (2003)

The rise of militancy in the beginning of twentieth century in India made the colonial authorities apprehensive of confining the nationalists on the mainland where they could spread their «dangerous ideas». The hunger strikes by the political convicts in the mainland prisons and in the cellular jail were an extension of the resistance movement against British colonialism. At the cost of three lives the hunger strike of 1933 kept the spirit of anti-colonial struggle alive during the lull created after Gandhi’s Civil Disobedience Movement and exposed the mistreatment of political prisoners and the dehumanisation involved in forced feeding. The narratives of participants put together with government records unearths a minor resistance movement against a mighty colonial power.
Intratracheal administration of perfluorochemical‐gentamicin suspension: A comparison to intravenous administration in normal and injured lungs* (2001)

Respiratory infections can lead to acute lung injury and perfusion abnormalities. We hypothesized that intratracheal (IT) administration of a perfluorochemical (PFC) gentamicin (G) suspension as compared to intravenous (IV) administration of gentamicin will result in higher lung tissue levels of gentamicin, while maintaining safe serum levels. To test this hypothesis, 21 lambs with normal and acid injured lungs were studied for 4 hr, using 2 different drug delivery methods, IT and IV. Lungs were injured with warm HCl acid in saline lavage, followed by partial liquid ventilation with perflubron (bolus FRC = 20 mL/kg). G at a dose of 5 mg/kg was delivered either IT (G-PFC; 20 mL/kg) or IV (aqueous injection with IT 20 mL/kg PFC alone). Throughout the study, serum G levels, arterial blood gases, respiratory system compliance, and mean arterial blood pressure were measured. Lung tissue G levels were measured at 4 hr and averaged across lobes. Physiologic gas exchange and pulmonary function were maintained throughout the protocol for both the normal and injured lungs. Intravenously administered G resulted in an initial 5-min serum concentration of 43 +/- 2.5 mcg/mL, followed by an exponential decline over the 4-hr protocol to a level of 2.1 +/- 0.23 mcg/mL at hr 4. The intratracheally administered G suspension resulted in a 5-min serum concentration of 1.8 +/- 0.98 mcg/mL and remained relatively constant throughout the protocol, with a 4-hr level of 1.6 +/- 0.29 mcg/mL. With respect to lung tissue G levels, IT administration was significantly more effective in delivering the drug to the normal lungs than IV (31.4 +/- 3.3 mcg/g vs. 4.0 +/- 0.7 mcg/g) 4 hr after administration. In the lung injury group, there was a small but significant difference in lung tissue G levels, with the IT-administered perfluorochemical-G suspension achieving greater levels than the IV-administered G (11.9 +/- 0.52 mcg/g vs. 10.1 +/- 0.8 mcg/g). Additionally, the drug delivered IV and IT in both the normal and injured lung models was homogeneously distributed throughout the lung. These data show that G lung tissue levels in both normal and injured lungs were higher in the IT group when compared to IV administration. The results of this study demonstrate that in normal and injured lungs, homogeneous G lung tissue levels can be more effectively achieved at lower serum levels when delivered IT in a G-PFC suspension as compared to IV administration.
Correction with blood T1 is essential when measuring post-contrast myocardial T1 value in patients with acute myocardial infarction (2013)

Post-contrast T1 mapping by modified Look-Locker inversion recovery (MOLLI) sequence has been introduced as a promising means to assess an expansion of the extra-cellular space. However, T1 value in the myocardium can be affected by scanning time after bolus contrast injection. In this study, we investigated the changes of the T1 values according to multiple slicing over scanning time at 15 minutes after contrast injection and usefulness of blood T1 correction. Eighteen reperfused acute myocardial infarction (AMI) patients, 13 cardiomyopathy patients and 8 healthy volunteers underwent cardiovascular magnetic resonance with 15 minute-post contrast MOLLI to generate T1 maps. In 10 cardiomyopathy cases, pre- and post-contrast MOLLI techniques were performed to generate extracellular volume fraction (Ve). Six slices of T1 maps according to the left ventricular (LV) short axis, from apex to base, were consecutively obtained. Each T1 value was measured in the whole myocardium, infarcted myocardium, non-infarcted myocardium and LV blood cavity. The mean T1 value of infarcted myocardium was significantly lower than that of non-infarcted myocardium (425.4±68.1 ms vs. 540.5±88.0 ms, respectively, p 0.05). The Ve did not show significant differences from apical to basal slices. Post-contrast myocardial T1 corrected by blood T1 or Ve, provide more stable measurement of degree of fibrosis in non-infarcted myocardium in short- axis multiple slicing.
MPC Model Individualization in Free-Living Conditions: A Proof-of-Concept Case Study (2017)

In the last years, Model Predictive Control (MPC) proved to be one of the most promising approaches for an Artifcial Pancreas (AP), a device for closed-loop blood glucose control in subjects afected by Type 1 Diabetes (T1D). MPC performance is highly infuenced by the quality of the model used for prediction. Moreover, the inter-patient variability characterising subjects with T1D increases the need of patient-tailored models. Recently, promising results have been obtained in silico using the UVA/Padova simulator in Soru et al. (2012) and Messori et al. (2016) where diferent individualization techniques have been studied and compared to the “average” model of the UVA/Padova adult population showing signifcant improvements in term of prediction ability. The aim of this paper is to verify the applicability of the technique described in Soru et al. (2012) and extend it to be used on free-living data collected without ad hoc clinical protocols. Data were collected during a 1 month trial in free-living conditions (Renard et al. (2016)). In this proof-of-concept case study, individualized models obtained with diferent identifcation parameters are compared with the “average” model that was used to synthetize the MPC controller used during that trial. The individualized models show superior prediction performance and prove robustness to non-optimal algorithm initialization in a selected test-case.
