Non-coherent communication in wireless point-to-point and relay channels: a geometric approach (2010)

We address the problem of non-coherent transmission in block Rayleigh fading channels. We focus on the point-to-point MIMO channel and the wireless relay channel without direct link. The problem of non-coherent space-time coding can be given a geometric interpretation as a packing problem in the Grassmann manifold. We use the differentiable structure of the Grassmann manifold for code constructions for the non-coherent channel. We present several novel constructions which exploit the geometry of the Grassmann manifold. We propose code constructions from spherical codes and lattice packings and develop a method for recursive construction of high-dimensional codes. We also address the problem of non-coherent transmission in wireless relay networks. We focus on one-way and two-way relaying protocols with half-duplex constraints on the terminals. For the one-way relaying network we present novel distributed space-time codes based on Grassmann codes for the point-to-point MIMO channel. For the two-way relaying channel we first introduce the concept of non-coherent communication, showing that non-coherent communication is possible, although no channel knowledge is present at neither the terminals nor at the relays. Further, we present bounds on the achievable two-way rate in the non-coherent setup. We show that the upper and the lower bound meet in the high SNR regime and differ from the capacity within a constant. As a byproduct we derive the degrees of freedom of the two-way network and show that amplify-and-forward is optimal strategy in the non-coherent setup. Motivated from the results, we present two communication schemes. The first one is a differential scheme which extends over the known differential schemes for one-way relaying and adapts to the specifics of the two-way channel. The second scheme is a genuine non-coherent scheme, designed for the block channel model.
An implementation of Cognitive Resource Management on LTE platform (2010)

In this paper we describe an LTE based demonstrator of the Universal Link Layer API (ULLA) and Cognitive Resource Manager (CRM) modules that are developed in ARAGORN project. The demonstrated LTE system comprises one LTE TDD eNode B and one User Equipment (UE). We first introduce ULLA and CRM framework and then demonstrate their suitability to be implemented with the existing LTE equipments. We show how, through ULLA, CRM is able to obtain PHY/MAC status information of the link between the eNode B and UE, and in turn change system parameters to achieve better resource utilization and transmission efficiency. The control logic can be implemented with simple adaptation or policy-based intelligent methods. The platform clearly shows the feasibility to use ULLA/CRM architecture for radio resource management in a LTE network. It also shows the neutrality of ULLA/CRM mechanisms towards PHY/MAC characteristics of LTE technology platform; hence the platform is viable to flexibly switch between technology platforms (e.g. between LTE access and WiFi access) under the control of ULLA/CRM.
Vibration and Acoustics Facilities at Manned Spacecraft Center (1964)

Vibration tests in support of manned space flight have been conducted by MSC since the origin of the Manned Spacecraft Center; this, of course, is ever increasing in both magnitude and scope and now embraces the field of acoustic testing. This paper discusses the sources of dynamic excitation in flight, whether vibration or acoustics, to the spacecraft or its occupants, and relates the resulting forces to the need for certain test facilities. Such facilities, either in existence or currently in construction, are described with regard to their physical make and environmental-simulation potential and their use is illustrated by descriptive examples, experimental programs, test procedures, and technical results.
Improving Load Range of Dual-Band Impedance Matching Networks Using Load-Healing Concept (2016)

A novel and very simple scheme to mend conventional dual-band impedance matching networks is presented. It involves the employment of a load-modifying element (load-healer) so as to extend the range of frequency-dependent complex load that could be matched. Two simple load-healers incorporated in the conventional T-network are used to illustrate the concept. The proposed scheme can be successfully applied in many situations where conventional matching networks are severely limited. Two prototypes operating concurrently at 1 and 2 GHz are designed corresponding to the two types of load-healer. They are implemented on FR4 substrate having a dielectric constant of 4.6, a substrate height of 1.5 mm, and a 35-μm copper cladding. The prototypes exhibit good agreement between their EM simulated and measured results.
Techniques for Accurate, Accelerated Processor Simulation: Analysis of Reduced Inputs and Sampling (2002)

Detailed execution-driven simulation is an important tool for computer architecture research. It is desirable to drive these simulations with standard benchmark programs that are commonly used to evaluate existing computer systems, such as the SPEC2000 suite. Unfortunately, simulating these benchmark programs to completion using full-detail, cycle-accurate simulation on the designated reference input sets results in intractably long simulation durations. This study evaluates and compares two techniques for combating long simulation times: reduced inputs and sampling. Our objective is to assess the ability of each to reduce simulation running times, while simultaneously minimizing the difference in the results generated by using these techniques relative to the results generated by simulating the benchmark programs to completion using the reference inputs. With the reduced input technique, new input sets are carefully generated by hand to produce run-time characteristics of the benchmark programs that are comparable to the overall characteristics produced when the programs are run with the standard inputs. Sampling, on the other hand, simulates only a small fraction of the program&#39;s overall execution in full, cycle-accurate detail using the reference inputs.
Antimicrobial effect and mode of action of terpeneless cold-pressed Valencia orange essential oil on methicillin-resistant Staphylococcus aureus (2012)

Multiple antibiotics resistance is becoming a serious problem in the management of Staph. aureus infections. In this study, the altered expression of cell wall-associated genes and subsequent cell lysis in MRSA caused by CPV suggest that it may be a potential antimicrobial agent to control antibiotic-resistant Staph. aureus.
Nylon–MOF Composites through Postsynthetic Polymerization (2018)

Hybridization of metal-organic frameworks (MOFs) and polymers into composites yields materials that display the exceptional properties of MOFs with the robustness of polymers. However, the realization of MOF-polymer composites requires efficient dispersion and interactions of MOF particles with polymer matrices, which remains a significant challenge. Herein, we report a simple, scalable, bench-top approach to covalently tethered nylon-MOF polymer composite materials through an interfacial polymerization technique. The copolymerization of a modified UiO-66-NH<sub>2</sub> MOF with a growing polyamide fiber (PA-66) during an interfacial polymerization gave hybrid materials with up to around 29 weight percent MOF. The covalent hybrid material demonstrated nearly an order of magnitude higher catalytic activity for the breakdown of a chemical warfare simulant (dimethyl-4-nitrophenyl phosphate, DMNP) compared to MOFs that are non-covalently, physically entrapped in nylon, thus highlighting the importance of MOF-polymer hybridization.
Building the HARMONI engineering model (2018)

HARMONI (High Angular Resolution MOnolithic Integral field spectrograph)<sup>1</sup> is a planned first-light integral field spectrograph for the Extremely Large Telescope. The spectrograph sub-system is being designed, developed, and built by the University of Oxford. The project has just completed the Preliminary Design Review (PDR), with all major systems having nearly reached a final conceptual design. As part of the overall prototyping and assembly, integration, and testing (AIT) of the HARMONI spectrograph, we will be building a full-scale engineering model of the spectrograph. This will include all of the moving and mechanical systems, but without optics. Its main purpose is to confirm the AIT tasks before the availability of the optics, and the system will be tested at HARMONI cryogenic temperatures. By the time of the construction of the engineering model, all of the individual modules and mechanisms of the spectrograph will have been prototyped and cryogenically tested. The lessons learned from the engineering model will then be fed back into the overall design of the spectrograph modules ahead of their development.
Rapid Diagnosis of Mycobacterium tuberculosis with Truenat MTB: A Near-Care Approach (2013)

This preliminary study shows that the Truenat MTB test allows detection of TB in approximately one hour and can be utilized in near-care settings to provide quick and accurate diagnosis.
Integrated plasmonic waveguides: A mode solver based on density of states formulation (2009)

We express the density of states (DOS) near guided resonances of plasmonic waveguides by using multiple-scattering theory. In direct analogy with the case of localized electronic defect states in condensed matter, we demonstrate that optical DOS variations follow a lorentzian profile near guided modes resonances. The lorentzian shape gives quantitative information on the guided modes (effective index, propagation length, and polarization state). We numerically investigate both leaky and bound (lossy) modes supported by dielectric-loaded surface-plasmon-polariton waveguides.
Path Length Sensitivity in Coherent Laser Beam Combining: Comparison between Architectures (2011)

The effect of path length errors on coherent beam combining performance is analyzed and measured for several combining architectures. Cavity loss and coherence characteristics are highly dependent on design, and can often be optimized.

Is Ketamine a Safe Anesthetic for Percutaneous Liver Biopsy in a Liver Transplant Recipient Immunosuppressed with Cyclosporine? (2004)

A 6-yr-old male patient underwent live related left lateral segment liver transplant for cryptogenic cirrhosis with portal hypertension. One month after the liver transplant the patient had an isolated liver transaminases increase. He was posted for percutaneous liver biopsy for suspected graft rejection under general anesthesia. The patient was administered ketamine 7 mg/kg along with glycopyrrolate 0.01 mg/kg IM in the preoperative area. He developed generalized tonic clonic seizures just before the biopsy and was treated with IV midazolam 1 mg and thiopental 60 mg. Percutaneous liver biopsy was obtained once the convulsions subsided. Both ketamine and cyclosporine have been implicated as having proconvulsant properties and may have been responsible for the seizures in our patient. Our experience prompted us to suggest that ketamine in a patient immunosuppressed with cyclosporine may not be safe and that alternative anesthetics may need to be considered for such procedures.
A224Ra-labeled polyoxopalladate as a putative radiopharmaceutical (2019)

Despite their attractive properties, internal targeted alpha therapies using 223/224Ra are limited to bone-seeking applications. As there is no suitable chelator available, the search for new carriers to stably bind Ra2+ and to connect it to biological target molecules is necessary. Polyoxopalladates represent a class of compounds where Ra2+ can be easily introduced into the Pd-POM core during a facile one-pot preparation. Due to the formation of a protein corona, the connection to other targeting (bio)macromolecules is possible.
Treatment of Presumed Hyperkalemia in the Prehospital Setting (2022)

The study evaluated a novel protocol for detecting and managing HK in the prehospital setting. It is feasible for EMS crews to administer this protocol, although a larger study is needed to make the results generalizable.
Admittance spectroscopy measurements of band offsets in Si/Si1−xGex/Si heterostructures (1992)

Admittance spectroscopy has been used to measure conduction- and valence-band discontinuities in Si/Si1−xGex heterojunctions (0&amp;lt;x&amp;lt;0.45). Most of the band-gap discontinuity was in the valence band. The measured valence-band offset increased with increasing Ge concentration in the strained Si1−xGex films, and it decreased when the Si1−xGex layers started to relax. These results indicate that admittance spectroscopy can be used to monitor the electronic properties of transistorlike Si/Si1−xGex/Si heterostructures.
Layered Iron Pnictide Superconductors: Discovery and Current Status (2008)

our paper reporting Tc of 26K in LaFeAsO 1-x F x was published on line in the Journal of American Chemical Society. The present article describes our research flow to this discovery and summarizes research advances on Fe (Ni)-based superconductors since then. Emphases are placed on that (1) all the superconducting materials reported to date have square lattice of Fe ions whose 3d orbitals predominately contribute the Fermi level. (2) Occurrence of crystallographic transition from tetragonal phase to a lower symmetry phase is required for parent phases of high Tc. (3) There are a variety of materials with different chemical compositions as candidates for high Tc superconductors. Even Fe ions may be substituted by Co ion without drastically reducing Tc. Fabrication of epitaxial thin films of Co-substituted Sr(FeAs) 2 exhibiting Tc=20K is also described.
Phenotypic Antimicrobial Susceptibility Testing with Deep Learning Video Microscopy (2018)

Timely determination of antimicrobial susceptibility for a bacterial infection enables precision prescription, shortens treatment time, and helps minimize the spread of antibiotic resistant infections. Current antimicrobial susceptibility testing (AST) methods often take several days and thus impede these clinical and health benefits. Here, we present an AST method by imaging freely moving bacterial cells in urine in real time and analyzing the videos with a deep learning algorithm. The deep learning algorithm determines if an antibiotic inhibits a bacterial cell by learning multiple phenotypic features of the cell without the need for defining and quantifying each feature. We apply the method to urinary tract infection, a common infection that affects millions of people, to determine the minimum inhibitory concentration of pathogens from human urine specimens spiked with lab strain E. coli (ATCC 43888) and an E. coli strain isolated from a clinical urine sample for different antibiotics within 30 min and validate the results with the gold standard broth macrodilution method. The deep learning video microscopy-based AST holds great potential to contribute to the solution of increasing drug-resistant infections.
A study of HLA class II antigens in an Italian paediatric population with coeliac disease. (1988)

One hundred and twenty-one Italian children with coeliac disease (CD) have been compared with a control population from the same geographical area for the distribution of HLA-DR and DQ antigens. The pattern of an increase in DR3, DR7, and of heterozygotes DR5/7 was associated with an excess of heterozygotes DQw2/DQw3 in the CD population. These findings suggest that epitopes determined by specific combinations of DQ alpha and beta chains (combinatorial determinants) predispose to the disease.
A Global Modular Equalizer Based on Forward Conversion for Series-Connected Battery Strings (2017)

The battery equalizer using a multi winding transformer has the advantages of easy isolation and fast balancing, but is very difficult to be applied to a large battery string with large numbers of cells connected in series due to the serious mismatching of multiple windings, the high voltage stress on switches, the additional demagnetizing circuits, bulky size, and high implementation complexity. Therefore, a global modular balancing architecture is proposed based on forward conversion, which integrates cell balancing, module balancing, and demagnetizing functions into one circuit, greatly reducing the volume, cost, energy loss, and implementation complexity. A prototype of the proposed equalizer for eight battery cells was built to validate the balancing performances, and a comparison between the proposed equalizer and existing solutions was presented. Experimental and comparative results show that the proposed topology exhibits a good balancing performance with strong robustness, and the measured peak efficiency is about 95.6%. In summary, the inherent advantages of the proposed global modular architecture are the fast balancing speed, high balancing efficiency, small size, low cost, ease of control, and the simultaneous any-cells-to-any-cells equalization among any cells.
OP26 Long-term safety of vedolizumab in ulcerative colitis and Crohn’s disease: final results from the GEMINI LTS study (2019)

Vedolizumab (VDZ), a gut-selective, humanised, α4β7 integrin monoclonal antibody, was approved in 2014 in the USA and EU to treat moderately to severely active ulcerative colitis (UC) and Crohn’s disease (CD). GEMINI long-term safety (LTS) is the longest VDZ continuous treatment study to date and provides unique data for VDZ therapeutic profiling. We report the final GEMINI LTS safety and efficacy findings. GEMINI LTS was a multi-national, multi-centre, open-label, Phase 3 study (NCT00790933/EudraCT 2015-000480-14). Patients with UC or CD received VDZ 300 mg IV every 4 weeks after they completed or withdrew from a Phase 2 study or one of the GEMINI Phase 3 studies or enrolled as VDZ-naïve de novo patients. Treatment continued until study completion or loss to follow-up (eg, after VDZ approval or expanded-access programme availability at the local site). Long-term safety was the primary endpoint and efficacy was an exploratory endpoint. A total of 894 patients with UC and 1349 with CD enrolled in GEMINI LTS for a planned treatment duration of 9 years. All patients had received ≥1 prior conventional therapy (Table 1). Adverse events (AEs) occurred in 93% of UC patients and 96% of CD patients; most frequent were UC (36%) and CD (35%) exacerbations and nasopharyngitis (UC, 28%; CD, 25%; Table 2). No new trends were observed for infections, malignancies, infusion-related reactions, or hepatic events. Serious AEs (SAEs) were reported in 31% of UC patients and 41% of CD patients; disease exacerbation was the most frequent SAE in both cohorts (UC, 13%; CD, 17%). VDZ was discontinued due to AEs in 15% of UC patients and 17% of CD patients, with UC or CD exacerbation (9% and 8%, respectively) the most frequent reason for discontinuation. There were no cases of progressive multi-focal leukoencephalopathy and 10 (UC, 4; CD, 6) deaths during the study. Clinical response was maintained long-term in patients who continued to receive VDZ throughout the entire study; however, the efficacy analysis was limited due to the expected, protocol-defined, patient loss to follow-up. The final GEMINI LTS results provide evidence that VDZ has a safety profile suitable for long-term treatment of UC and CD. In this carefully monitored population receiving VDZ in a clinical trial setting, there continue to be no unexpected or new safety concerns. Abstract OP026 – Table 1.

Peptide tags for enhanced cellular and protein adhesion to single‐crystalline sapphire (2007)

In order to facilitate a novel means for coupling proteins to metal oxides, peptides were identified from a dodecamer peptide yeast surface display library that bound a model metal oxide material, the C, A, and R crystalline faces of synthetic sapphire (alpha-Al(2)O(3)). Seven rounds of screening yielded peptides enriched in basic amino acids compared to the naive library. While the C-face had a high background of endogenous yeast cell binding, the A- and R faces displayed clear peptide-mediated cell adhesion. Cell detachment assays showed that cell adhesion strength correlated positively with increasing basicity of expressed peptides. Cell adhesion was also shown to be sensitive to buffer ionic strength as well as incubation with soluble peptide (with half maximal inhibition of cell binding at approximately 5 microM peptide). Next, dodecamer peptides cloned into yeast showed that lysine led to stronger interactions than arginine, and that charge distribution affected adhesion strength. We postulate binding to arise from peptide geometries that permit conformation alignment of the basic amino acids towards the surface so that the charged groups can undergo local electrostatic interactions with the surface oxide. Lastly, peptide K1 (-(GK)(6)) was cloned onto the c-terminus of maltose binding protein (MBP) and the resultant mutant protein showed a half-maximal binding at approximately 10(-7)-10(-6) M, which marked a approximately 500- to 1,000-fold binding improvement to sapphire's A-face as compared with wild-type MBP. Targeting proteins to metal oxide surfaces with peptide tags may provide a facile one-step alternative coupling chemistry for the formation of protein bioassays and biosensors.
