On the Limits of Digital Back-Propagation in Fully Loaded WDM Systems (2016)

We investigate upper bounds for single-channel and multi-channel digital back-propagation (BP) in fully loaded wavelength-division multiplexed systems. Using the time-domain model for nonlinear interference noise, we expand previous estimates of BP gains to accurately cover a wide range of system configurations, including a variety of modulation formats from quadrature phase-shift keying to 256-ary quadrature amplitude modulation. In typical scenarios, the potential benefit of singlechannel BP is limited to ~0.5 dB in terms of the peak signal-tonoise ratio, and to ~1 and ~1.2 dB in the case of joint threeand five-channel BP. The additional gain from increasing the number of jointly back-propagated channels beyond five is limited to ~0.1 dB per additional back-propagated channel. We also study the role of BP for receivers that separately compensate for nonlinear phase and polarization rotation noise and show that while the additional gain provided by BP does not change significantly in long-haul systems, it holds the promise of being notably higher in short-reach ultra-high-capacity systems.
Wide-band power divider miniaturized by combining CRLH ZOR bandpass filters (2012)

In this paper, a new method is suggested to reduce the size of a wide-band power divider. It is made compact with the help of a novel Metamaterial wide-band power divider. The power divider has the Zeroth Order Resonant (ZOR) bandpass filter that is as small as approximately about λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">g</sub> /17. This power divider is clearly different from others in that the proposed design uses simple microstrip structured Composite Right and Left-Handed (CRLH) filters. The power divider is analyzed based on even- and odd- mode approach. The power divider is measured and compared with the prediction. Also, the size reduction effect is addressed.
Fast Spectrum Shaping for Next-Generation Wireless Networks (2013)

Spectrum management and device coordination for dynamic spectrum access (DSA) networks have received significant research attention. However, current wireless devices have yet to fully embrace DSA networks due to the difficulties in realizing spectrum-agile communications. We address the practical hurdles and present solutions toward implementing DSA devices, answering an important question “what is a simple practical extension to current wireless devices that makes them spectrum-agile?” To this end, we propose RODIN, a general per-frame spectrum-shaping protocol that has the following features to support DSA in commercial off-the-shelf (COTS) wireless devices: direct manipulation of passband signals from COTS devices, fast FPGA-based spectrum shaping, and a novel preamble design for spectrum agreement. RODIN uses an FPGA-based spectrum shaper together with a preamble I-FOP to achieve per-frame spectrum shaping with a delay of under 10 μs.
Receptors for insulin-like growth factor-I in plasma membranes isolated from bovine mesenteric arteries (1988)

Binding of IGF-I to plasma membranes from bovine mesenteric arteries was studied. The maximal specific binding of IGF-I was found to be 7.4 +/- 1.7% of total 125I-IGF-I added to the incubation medium. Unlabelled IGF-I displaced 125I-IGF-I with an IC50 value of 0.5 nmol/l and a maximal displacement of 64.2 +/- 2.8% of total binding. The potency of insulin to displace 125I-IGF-I was 100-1000-fold lower. Cross-linking of 125I-IGF-I to the receptor with disuccinimidyl suberate, followed by SDS-polyacrylamide gel electrophoresis under reducing conditions showed an IGF-I binding protein with a molecular weight of 146,000 Dalton. In summary, we have shown the presence of receptors for IGF-I in plasma membranes isolated from macrovessels. The binding characteristics and the size of the binding unit were found to be similar to those of the IGF-I receptor found in cultured vascular smooth muscle cells. Furthermore, insulin at high concentrations was found to interact with the IGF-I receptor.

Description and In-Vitro Test Results of a New Wearable/Portable Device for Extracorporeal Blood Ultrafiltration (2019)

This paper presents the design of Rene Artificiale Portatile (RAP), a novel wearable and portable device for extracorporeal blood ultrafiltration, capable of providing remote treatment of fluid overload in patients with kidney diseases and/or congestive heart failure. The development of the device is based on a new design paradigm, since the layout of the device is box-shaped, as to fit a backpack or a trolley case, differentiating it from other existing devices. The efficient layout and component placement guarantee minimalization and ergonomics, as well as an efficient and cost-effective use. The redundant control architecture of the device has been implemented to ensure a high level of safety and an effective implementation of the clinical treatment. The consistency of the design and its effective implementation are assessed by the results of the preliminary in-vitro tests presented and discussed in this work.
Effect of annealing on structural changes and oxygen diffusion in amorphous HfO2 using classical molecular dynamics (2018)

Non-volatile memory is a promising alternative to present memory technologies. Oxygen vacancy diffusion has been widely accepted as one of the reasons for the resistive switching mechanism of transition-metal-oxide based resistive random access memory. In this study, molecular dynamics simulation is applied to investigate the diffusion coefficient and activation energy of oxygen in amorphous hafnia. Two sets of empirical potential, Charge-Optimized Many-Body (COMB) and Morse-BKS (MBKS), were considered to investigate the structural and diffusion properties at different temperatures. COMB predicts the activation energy of 0.53 eV for the temperature range of 1000–2000 K, while MBKS predicts 2.2 eV at high temperature (1600–2000 K) and 0.36 eV at low temperature (1000–1600 K). Structural changes and appearance of nano-crystalline phases with increasing temperature might affect the activation energy of oxygen diffusion predicted by MBKS, which is evident from the change in coordination number distribution and radial distribution function. None of the potentials make predictions that are fully consistent with density functional theory simulations of both the structure and diffusion properties of HfO2. This suggests the necessity of developing a better multi-body potential that considers charge exchange.
Cover Picture: Harvesting piezoelectric potential from zinc oxide nanoflowers grown on textile fabric substrate (Phys. Status Solidi RRL 11/2013) (2013)

The fabrication of novel devices for harvesting energy from various resources is emerging as an active area of research. The coupling between electrical and mechanical properties of materials, i.e. piezoelectricity, is one of the approaches with great potential. On the other hand, the use of flexible and nonconventional substrates is a popular approach for the fabrication of nanogenerators relying on the piezoelectric property due to the possibility of efficient transfer of mechanical energy. Khan et al. (pp. 980–984) harvest the piezoelectric potential from ZnO nanoflowers grown on a textile fabric substrate by applying an external load. Moreover, a review of the literature reveals that the morphology of the ZnO nanostructures can influence the harvested piezoelectric output. In the investigation by Khan et al., the obtained results proved the effect of morphology on the piezoelectric output from ZnO nanostructure. In addition, the development of a ZnO nano- generator on textile fabrics is a useful step towards introducing electronic devices on non-conventional substrates and for new applications, e.g. self-powered nanosensors on textile fabrics.
Molecular characterization of a common fragile site ( FRA7H ) on human chromosome 7 by the cloning of a simian virus 40 integration site (1998)

Common fragile sites are chromosomal loci prone to breakage and rearrangement, hypothesized to provide targets for foreign DNA integration. We cloned a simian virus 40 integration site and showed by fluorescent in situ hybridization analysis that the integration event had occurred within a common aphidicolin-induced fragile site on human chromosome 7, FRA7H. A region of 161 kb spanning FRA7H was defined and sequenced. Several regions with a potential unusual DNA structure, including high-flexibility, low-stability, and non-B-DNA-forming sequences were identified in this region. We performed a similar analysis on the published FRA3B sequence and the putative partial FRA7G, which also revealed an impressive cluster of regions with high flexibility and low stability. Thus, these unusual DNA characteristics are possibly intrinsic properties of common fragile sites that may affect their replication and condensation as well as organization, and may lead to fragility.
Metal self-expandable covered temporary urethral stent Allium in patients with irreversibile uroobstruction: Ten-year experience (2014)

Aim of this study is to judge effectiveness of new design, temporary, cover, metal selective urethral Allium stents in lower urinary tract symptoms treatment concerning all peri and post procedural complications. Material and methods: We observed group of 40 patients with longstanding history of lower urinary tract symptom, in which outflow obstruction was localized in bulbar urethra in 24 pts and in prostatic urethra in 13 pts. Residual voiding volume and prostate volume measurements by ultrasonography, urethrocystography, urine culture and uroflowmetry (bulbar urethra stricture PTS) were done before stent insertion. Procedure was done in all cases but one in ambulatory conditions, under local anesthesia with oral antibiotics administration day before and 5 days after. Objective and subjective parameters of stent effectiveness were estimated and statistically revealed. Results: Majority of pts (32/40) were satisfied with all the aspects of the procedure and with quality of life while urethra was stented. Urinary infection did not happen in any case, encrustation of the migrated stent occurred in 2 cases (6,4%). Emptying of the bladder was adequate while wearing either prostatic or bulbar urethra stent. Residual volume was significantly smaller, urinary flow significantly higher. In pts with bulbar urethra stricture urinary flow and morphology of patent urethra lumen, 6 months after stent extraction suggested prolonged-permanent recanalisation results. Conclusion: Site specific, metal Allium urethral stents enable adequate emptying of the urinary bladder with minimal and transient patient discomfort. Stent insertion and explantation are simple procedures to perform, when correctly indicated without significant early and late complications.
Cytogenetic Prognostication Within Medulloblastoma Subgroups (2014)

Combining subgroup and cytogenetic biomarkers with established clinical biomarkers substantially improves patient prognostication, even in the context of heterogeneous clinical therapies. The prognostic significance of most molecular biomarkers is restricted to a specific subgroup. We have identified a small panel of cytogenetic biomarkers that reliably identifies very high-risk and very low-risk groups of patients, making it an excellent tool for selecting patients for therapy intensification and therapy de-escalation in future clinical trials.
Binaural Reproduction of Finite Difference Simulations Using Spherical Array Processing (2015)

Due to its efficiency and simplicity, the finite-difference time-domain method is becoming a popular choice for solving wideband, transient problems in various fields of acoustics. So far, the issue of extracting a binaural response from finite difference simulations has only been discussed in the context of embedding a listener geometry in the grid. In this paper, we propose and study a method for binaural response rendering based on a spatial decomposition of the sound field. The finite difference grid is locally sampled using a volumetric array of receivers, from which a plane wave density function is computed and integrated with free-field head related transfer functions, in the spherical harmonics domain. The volumetric array is studied in terms of numerical robustness and spatial aliasing. Analytic formulas that predict the performance of the array are developed, facilitating spatial resolution analysis and numerical binaural response analysis for a number of finite difference schemes. Particular emphasis is placed on the effects of numerical dispersion on array processing and on the resulting binaural responses. Our method is compared to a binaural simulation based on the image method. Results indicate good spatial and temporal agreement between the two methods.
The Lossless, Resonant, Minimum Scattering Approximation for Fast Phased Array Design (2018)

The classical framework for phased array beamforming, analysis, and design is based on the array factor approximation. As research in antenna arrays has progressed, attention has turned to sophisticated, high sensitivity applications that require more accurate models. Mutual coupling, edge effects, surface waves, and other non-ideal effects can be accounted for full wave numerical methods, but the run time for the model becomes large, and design optimization can be unduly time consuming. A middle ground between the array factor and full wave numerical models is provided by the lossless, resonant, minimum scattering (LRMSA)approximation. Embedded element radiation patterns with open circuit loads on the element ports are approximated using an analytically known or modeled isolated element pattern, and mutual coupling is included to first order using the element pattern overlap matrix and relationships from the network theory of antenna arrays. We give an overview of the LRMSA method for fast phased array modeling and design in this paper, and the presentation will include numerical comparisons and design examples for a variety of phased array application areas.
Binary Information from Open Clusters Using SEDS (BINOCS) Project: The\n Dynamical Evolution of the Binary Populations in Cluster Environments (2015)

Studying the internal dynamics of stellar clusters is conducted primarily\nthrough N-Body simulations. One of the major inputs into N-Body simulations is\nthe binary star frequency and mass distribution, which is currently constrained\nby relations derived from field binary stars. However to truly understand how\nclustered environments evolve, binary data from within star clusters is needed\nincluding masses. Detailed information on binaries masses, primary and\nsecondary, in star clusters has been limited to date. The primary technique\ncurrently available has been radial velocity surveys that are limited in depth.\nUsing previous two-band photometry-based studies that may cover different mass\nranges produce potentially discrepant interpretations of the observed binary\npopulation. We introduce a new binary detection method, Binary INformation from\nOpen Clusters Using SEDs (BINOCS) that covers the wide mass range needed to\nimprove cluster N-body simulation inputs and comparisons. Using newly-observed\nmulti-wavelength photometric catalogs (0.3 - 8 microns) of the key open\nclusters with a range of ages, we can show that the BINOCS method determines\naccurate binary component masses for unresolved cluster binaries through\ncomparison to available RV-based studies. Using this method, we present results\non the dynamical evolution of binaries from 0.4 - 2.5 solar masses within five\nprototypical clusters, spaning 30 Myr to 3.5 Gyr, and how the binary\npopulations evolve as a function of mass.\n
NT-proBNP and high intensity care for acute heart failure: the STRONG-HF trial (2023)

Among patients with acute HF enrolled in STRONG-HF, HIC reduced 180-day HF readmission or death regardless of baseline NT-proBNP. GRMT up-titration early post-discharge, utilizing increased NT-proBNP as guidance to increase diuretic therapy and reduce the GRMT up-titration rate, resulted in the same 180-day outcomes regardless of early post-discharge NT-proBNP change.
Bandwidth-efficient OFDM cooperative protocol with applications to UWB communications (2006)

In this paper, we propose an OFDM cooperative protocol that not only achieves full diversity but also efficiently utilizes available bandwidth. The proposed protocol exploits limited feedback from the destination terminal (central node) such that each relay is able to help forward information of multiple sources in one OFDM symbol. To specify how relay-source pairs should be assigned, we propose two practical relay-assignment schemes, including fixed-location scheme in which the relays are fixed at optimum locations, and centralized-control scheme in which the relays are assigned by the central node. We provide outage probability analysis of the proposed protocol in wireless indoor environment. Moreover, a lower bound on the outage probability of any relay-assignment schemes is established, and the performance of the proposed relay-assignment schemes is analyzed. We also investigate the application of the proposed protocol to enhance the performance of UWB systems. In UWB wireless indoor scenarios, both theoretical and simulation results show that the proposed cooperative protocol can achieve 75% power saving and 200% coverage extension compared to the noncooperative UWB system proposed in the IEEE 802.15.3a standard.
5G and NOA (2021)

NAMUR Open Architecture (NOA) follows the concept of creating an Industry 4.0 world that stands beside the classical automation pyramid. In this concept, devices which previously only had a communication path within the OT world receive a controlled second communication path into the IT world, where NOA realizes monitoring and optimization applications. The challenge lies in retrofitting communication in brownfield plants, where a large fraction of field devices and many control devices currently only have analog and/or OT communication. In this paper we introduce 5G and the standards contain and show that these are a very promising path to retrofit communication from the OT to the IT world of NOA. This allows to retrofit NOA, but also forms the basis for future Industry 4.0 szenarios, in which the automation pyramid may be dropped.&#x0D;

Electroluminescent Device Made of Diamond (1991)

A diamond light-emitting device was fabricated using boron-doped epitaxial film and a Schottky junction. The emission was white with a spectrum which was quite broad and centered at 530 nm. This spectrum was found to be similar to the spectrum obtained by cathodoluminescence from the boron-doped epitaxial film. The emission is considered to be caused by the injection electroluminescence and the color center named “Band-A” is considered to be the emitted center.
Relugolix Combination Therapy in Women With Uterine Fibroids and Adenomyosis: LIBERTY 1 and 2 Trials [ID: 1345355] (2023)

INTRODUCTION: Adenomyosis and uterine fibroids (UFs) may coexist in women with heavy menstrual bleeding (HMB). Relugolix combination therapy (Relugolix-CT: relugolix 40 mg, estradiol 1 mg, norethindrone acetate 0.5 mg) is approved in the United States to treat HMB associated with UFs and moderate-to-severe pain associated with endometriosis. A post-hoc analysis of the pivotal, 24-week LIBERTY 1 and 2 studies evaluated the efficacy of Relugolix-CT versus placebo in the subgroup with ultrasound evidence of adenomyosis. METHODS: Baseline ultrasound images from women enrolled in the replicate, IRB-approved LIBERTY studies were evaluated for adenomyosis using predefined criteria. Primary endpoint: proportion of study completers with baseline adenomyosis who were HMB responders, defined as 50% or higher reduction in menstrual blood loss (MBL) volume from baseline and less than 80-mL MBL over the last 35 days. Pooled LIBERTY 1 and 2 results are presented. RESULTS: Of women who completed the LIBERTY studies, 111/610 (18.2%) had ultrasound evidence of adenomyosis at study entry. The prevalence of adenomyosis was similar between treatment groups (18.3% and 14.0% for Relugolix-CT and placebo, respectively). In this subgroup, 83.8% of women treated with Relugolix-CT were HMB responders versus 27.6% of women who received placebo; responders in the overall population were 72.3% and 16.8%, respectively. Additionally, 64.9% of women in this subgroup who received Relugolix-CT were amenorrheic over the last 35 days of treatment, versus 6.9% of women treated with placebo. CONCLUSION: Relugolix-CT effectively reduced HMB in women with UFs and adenomyosis through 24 weeks. Efficacy in this subgroup of women was generally similar to the overall study population.
A mobile-bearing total knee prosthesis compared with a fixed-bearing prosthesis (2003)

Before proceeding to longer-term studies, we have studied the early clinical results of a new mobile-bearing total knee prosthesis in comparison with an established fixed-bearing device. Patients requiring bilateral knee replacement consented to have their operations under one anaesthetic using one of each prosthesis. They also agreed to accept the random choice of knee (right or left) and to remain ignorant as to which side had which implant. Outcomes were measured using the American Knee Society Score (AKSS), the Oxford Knee Score (OKS), and determination of the range of movement and pain scores before and at one year after operation. Preoperatively, there was no systematic difference between the right and left knees. One patient died in the perioperative period and one mobile-bearing prosthesis required early revision for dislocation of the meniscal component. At one year the mean AKSS, OKS and pain scores for the new device were slightly better (p < 0.025) than those for the fixed-bearing device. There was no difference in the range of movement. We believe that this is the first controlled, blinded trial to compare early function of a new knee prosthesis with that of a standard implant. It demonstrates a small but significant clinical advantage for the mobile-bearing design.
