Li3V(MoO4)3: A New Material for Both Li Extraction and Insertion (2010)

Besides topotactical Li insertion, Li deinsertion also is possible for the new potential electrode material Li3V(MoO4)3, in contrast to isostructural Li3Fe(MoO4)3. This new phase crystallizes in an orthorhombic NASICON-type structure with large channels along the crystallographic a-axis, which are half-filled by Li atoms. A reversible reduction of Li3V(MoO4)3 occurs at 2.1 V, with the formation of isostructural Li4V(MoO4)3, whereas an oxidation to Li2V(MoO4)3 is found at 3.7 V, preserving the space-group symmetry. The first charge/discharge cycle differs significantly from the following ones. According to X-ray photoelectron spectroscopy (XPS) measurements, Li extraction is associated with vanadium oxidation (V3+ ⇒ V4+) and Li intercalation is accompanied mainly by molybdenum reduction (Mo6+ ⇒ Mo5+), but also is partially associated with vanadium reduction (V3+ ⇒ V2+). In situ synchrotron diffraction on a LixV(MoO4)3 cathode with x ≈ 3 during the first discharge/charge cycle revealed a monotonous increase of the lattice volume and of the lattice parameter a during Li insertion from x = 3 to x = 3.5, but a multiphase mechanism for 3.5 ≤ x ≤ 4. At x ≤ 2.95, a monotonous decrease of the lattice volume was observed. The paramagnetic moments of LixV(MoO4)3 (x = 2, 3, 4) are smaller than the theoretical values, calculated for spin-only contributions from V4+, V3+, and V2+, respectively, which might indicate the partially delocalized character of the V valence electrons.
Recombinant modified vaccinia virus Ankara–simian immunodeficiency virusgag polelicits cytotoxic T lymphocytes in rhesus monkeys detected by a major histocompatibility complex class I/peptide tetramer (1998)

The utility of modified vaccinia virus Ankara (MVA) as a vector for eliciting AIDS virus-specific cytotoxic T lymphocytes (CTL) was explored in the simian immunodeficiency virus (SIV)/rhesus monkey model. After two intramuscular immunizations with recombinant MVA-SIVSM gag pol, the monkeys developed a Gag epitope-specific CTL response readily detected in peripheral blood lymphocytes by using a functional killing assay. Moreover, those immunizations also elicited a population of CD8+ T lymphocytes in the peripheral blood that bound a specific major histocompatibility complex class I/peptide tetramer. These Gag epitope-specific CD8+ T lymphocytes also were demonstrated by using both functional and tetramer-binding assays in lymph nodes of the immunized monkeys. These observations suggest that MVA may prove a useful vector for an HIV-1 vaccine. They also suggest that tetramer staining may be a useful technology for monitoring CTL generation in vaccine trials in nonhuman primates and in humans.
A new Method for the Calculation of Partition Coefficients from Experimental Data for Both Mixtures and Pure Compounds (1992)

Abstract A new method for estimating partition coefficients from data collected using the filter probe extractor (or similar equipment) is described. The method was developed to analyse the data from a two‐component mixture, which cannot be dealt with using the conventional form of data analysis. It is suggested that not only is this method suitable for mixtures but that it also offers advantages for pure compounds.
Pyostomatitis Vegetans (1985)

Pyostomatitis vegetans is a rarely occurring disorder of the oral mucosa, which has a dramatic clinical picture and a striking histopathologic pattern. Moreover, the condition is a highly specific oral mucosal marker for inflammatory bowel disease, particularly ulcerative colitis. Our findings in two cases and a review of the literature emphasize the relationship of pyostomatitis vegetans to inflammatory bowel disease and the vegetating dermatoses.
Antimicrobial Chrysophaentin Analogs Identified from Laboratory Cultures of the Marine Microalga Chrysophaeum taylorii (2019)

A laboratory culture of the colonial marine alga Chrysophaeum taylorii NIES-1699 yielded a set of new bioactive chrysophaentin analogs, and their structures were determined by HRESIMS and NMR spectroscopy. Differences in the metabolites identified between cultured C. taylorii NIES-1699 and field-collected strains from the U.S. Virgin Islands revealed additional structure-activity relationships for the Gram-positive antibiotic activity of the chrysophaentins. The presence of new hemichrysophaentins and a C-C linked biphenyl analog suggest novel features of their biosynthetic pathway. Bayesian analysis of the alignment of the 18S rRNA gene places the microalga C. taylorii in the pelagophyte clade.
Associations between the gut microbiome and fatigue in cancer patients (2021)

Fatigue is the most prevalent symptom of cancer and its treatments. Changes in the intestinal microbiome have been identified in chronic fatigue syndrome and other neuropsychiatric disorders, and cancer patients. However, the association between intestinal microbiome and fatigue in patients with advanced cancers has not been evaluated. Understanding the connection between intestinal microbiome and fatigue will provide interventional and therapeutic opportunities to manipulate the microbiome to improve fatigue and other patients' reported outcomes. In this project, we aimed to identify associations between microbiome composition and fatigue in advanced cancer patients. In this cross-sectional observational study at a tertiary cancer care center, we included 88 patients with advanced, metastatic, unresectable cancers who were in a washout period from chemotherapy. We measured fatigue using the MD Anderson Symptom Inventory-Immunotherapy fatigue score, and used 16srRNA to analyze intestinal microbiome. Using correlation analysis we found that Eubacterium hallii was negatively associated with fatigue severity scores (r = - 0.30, p = 0.005), whereas Cosenzaea was positively associated with fatigue scores (r = 0.33, p = 0.0002). We identified microbial species that exhibit distinct composition between high-fatigued and low-fatigued cancer patients. Further studies are warranted to investigate whether modulating the microbiome reduces cancer patients' fatigue severity and improves their quality of life.
Robust adaptive flow control in high speed telecommunication networks (2002)

We consider a single controlled traffic source, sharing a bottleneck node with other (higher priority) sources, whose traffic is modeled by an ARMA process. The controlled source adapts dynamically its transmission rate to the remaining available bandwidth. We focus in this paper on the case when the ARMA parameters are unknown. We use an H/sup /spl infin// approach, and design a controller which combines identification (of the ARMA parameters) with the control in a novel way.

Design of FLAT-SUGAR: Randomized Trial of Prandial Insulin Versus Prandial GLP-1 Receptor Agonist Together With Basal Insulin and Metformin for High-Risk Type 2 Diabetes (2015)

FLAT-SUGAR is a proof-of-concept study testing whether, in a population of individuals with type 2 diabetes and high cardiovascular risk, the GLIPULIN regimen can limit glycemic variability more effectively than BBI, reduce levels of cardiovascular risk markers, and favorably alter albuminuria and electrocardiographic patterns. We successfully randomized a population that has sufficient power to answer the primary question, address several secondary ones, and complete the protocol as designed.
<title>Improved resolution of photonic A/D conversion using oversampling techniques</title> (1998)

The majority of the signals encountered in nature ar analog while the preferred method of processing these signals is digital. Digital signal processors provide higher resolution, improved flexibility and functionality, and improved noise immunity over its analog counterparts. As a result, the analog-to-digital, (A/D) interface is generally considered to be the most critical part of any signal acquisition and processing systems. Because of the difficulty in achieving high-resolution and high-speed A/D converters, this A/D interface has been and continues to be a barrier to the realization of high-speed, high-throughput systems. Electronic A/D techniques have been investigated but appear to be limited. (Sigma) (Delta) techniques have been successful in providing high-resolution converters but only for audio frequency signal. Optical approaches have also ben investigated to leverage the wide bandwidth and parallelism of optics but most have been limited by the component linearity, device speed, or dynamic range. We previously proposed and demonstrate an optical approach to A/D conversion based on oversampling techniques using a modification of the (Sigma) (Delta) architecture and multiple quantum well modulators as the optical devices. Here we describe other approaches to oversampling A/D conversion incorporating space-time processing of optical signals leading to ultra-high resolution at very high speed.
2‐Dimensional Transition Metal Dichalcogenides with Tunable Direct Band Gaps: MoS2(1–x)Se2x Monolayers (2013)

MoS2(1-x) Se2x single-layer films are prepared using a mixture of organic selenium and sulfur precursors as well as a solid molybdenum source. The direct bandgaps are found to scale nearly linearly with composition in the range of 1.87 eV (pure single-layer MoS2 ) to 1.55 eV (pure single-layer MoSe2 ) permitting straightforward bandgap engineering.
Vascular Heterograft: Human Umbilical Cord Veinas an Aortic Substitute in Baboon (1973)

Human umbilical cord vein was employed as an arterial substitute for the infrarenal aorta in baboons. The veins were found patent at the time of removal, three days to eight weeks after implantation. Formation of aneurysms occurred in grafts implanted three weeks or longer.
Mechanism of catalytic gasification of coal char. Quarterly technical progress report No. 4, 1 July-30 September 1981 (1981)

The objective of this study is to determine the mechanisms involved in the catalytic gasification reactions of coal char and to identify the specific reaction steps and the parameters that control the catalytic process. The catalytic process involves three phases, the char, the catalyst dispersion on the char surface, and the gaseous reactants. Progress reports are presented for the following areas of investigation: (1) chemical and physical changes in catalyst-impregnated char; (2) kinetics of gasification of catalyst-impregnated char; (3) surface area and gasification kinetics; and (4) identification of reaction intermediates in the solid.

Size determination of hyaluronan using a gas-phase electrophoretic mobility molecular analysis (2011)

Hyaluronan (HA) is a linear non-sulfated polysaccharide mainly found in the extracellular matrix. The size of HA can vary from a few disaccharides up to at least 25,000 units, reaching molecular weights of 10 10(3) kDa. HA has many biological functions, and both its size and tissue concentration play an important role in many physiological and pathological processes. It is relatively easy to determine the HA concentration using enzyme-linked binding protein assays, but the molecular weight of HA has so far been shown to be a more challenging task to measure. Here, we present a method for size determination of HA using gas-phase electrophoretic mobility molecular analysis (GEMMA), which utilizes the electrophoretic mobility of molecules in air to estimate the molecular weight of the analyte. We show that this method gives reliable molecular weight estimations of HA in the range of 30-2400 kDa, which covers almost its whole biological range. The average measuring time for one GEMMA spectrum is between 5 and 10 min using only 6 pg of HA. In addition, the peak area in a GEMMA spectrum can be used to estimate the HA concentration in the sample. The high sensitivity and small sample volumes make GEMMA an excellent tool for both size determinations and estimation of concentration of samples with low HA concentration, as is the case for HA extracted from small tissue samples.
The Relationship Between Electrical Energy Delivered by Deep Brain Stimulation and Levodopa-Induced Dyskinesias in Parkinson's Disease: A Retrospective Preliminary Analysis (2021)

<b>Background:</b> Adaptive Deep Brain Stimulation (aDBS) is now considered as a new feasible and effective paradigm to deliver DBS to patients with Parkinson's disease (PD) in such a way that not only stimulation is personalized and finely tuned to the instantaneous patient's state, but also motor improvement is obtained with a lower amount of energy transferred to the tissue. Amplitude-controlled aDBS was shown to significantly decrease the amplitude-driven total electrical energy delivered to the tissue (aTEED), an objective measure of the amount of energy transferred by DBS amplitude to the patient's brain. However, there is no direct evidence of a relationship between aTEED and the occurrence of DBS-related adverse events in humans. <b>Objective:</b> In this work, we investigated the correlation of aTEED with the occurrence of levodopa-induced dyskinesias pooling all the data available from our previous experiments using aDBS and cDBS. <b>Methods:</b> We retrospectively analyzed data coming from 19 patients with PD undergoing surgery for STN-DBS electrode positioning and participating to experiments involving cDBS and aDBS delivery. Patients were all studied some days after the surgery (acute setting). The aTEED and dyskinesia assessments (Rush Dyskinesia Rating Scale, RDRS) considered in the Med ON-Stim ON condition. <b>Results:</b> We confirmed both that aTEED values and RDRS were significantly lower in the aDBS than in cDBS sessions (aTEED mean value, cDBS: 0.0278 ± 0.0011 j, vs. aDBS: 0.0071 ± 0.0003 j, <i>p</i> < 0.0001 Wilcoxon's rank sum; normalized RDRS mean score, cDBS: 0.66 ± 0.017 vs. aDBS: 0.45 ± 0.01, <i>p</i> = 0.025, Wilcoxon's rank sum test). In addition, we found a direct significant correlation between aTEED and RDRS (ρ = 0.44, <i>p</i> = 0.0032, Spearman's correlation). <b>Conclusions:</b> Our results provide a first piece of evidence that aTEED is correlated to the amount of levodopa-induced dyskinesias in patients with PD undergoing STN-DBS, thus supporting the role of aDBS as feasible and safe alternative to cDBS.
Experimental Observation of Monastatic Reflection by Elastic Spheres in Water (1972)

Careful comparison of steady-state theory and experiment has shown that outstanding features such as nulls in the reflection solution vs ka for spheres can be identified with precision by pulse experiments. The systematic influence of experimental parameters such as elastic constants and ambient temperature is discussed. A persistent discrepancy of 0.05% in wavenumber between theory and experiment has been observed.
Integration and calibration of NDIR CO 2 low-cost sensors, and their operation in a sensor network covering Switzerland (2019)

Abstract. More than 300 LP8 CO2 sensors were integrated into sensor units and evaluated for the purpose of long-term operation in the Carbosense CO2 sensor network in Switzerland. Prior to deployment, all sensors were calibrated in a pressure and climate chamber, and in ambient conditions co-located with a reference instrument. To investigate their long-term performance and to test different data processing strategies, 18 sensors were deployed at five locations equipped with a reference instrument after calibration. Their accuracy during 19 to 25 months deployment was between 8 to 12 ppm. This level of accuracy requires careful sensor calibration prior to deployment, continuous monitoring of the sensors, efficient data filtering, and a procedure to correct drifts and jumps in the sensor signal during operation. High relative humidity (&gt; ∼85 %) impairs the LP8 measurements, and corresponding data filtering results in a significant loss during humid conditions. The LP8 sensors are not suitable for the detection of small regional gradients and long-term trends. However, with careful data processing, the sensors are able to resolve CO2 changes and differences with a magnitude larger than about 20 ppm. Thereby, the sensor can resolve the site-specific CO2 signal at most locations in Switzerland. A low power network (LPN) using LoRaWAN allowed reliable data transmission with low energy consumption, and proved to be a key element of the Carbosense low-cost sensor network.
Aberration control for 70-nm optical lithography (2001)

This paper examines the control of optical aberrations in an advanced step-and-scan system operating at 157 nm wavelength that uses catadioptric projection optics. Optical lithography will need to operate at K-factors approaching 0.33 using 157 nm wavelength with extremely high numerical apertures.
Analysis of lithium-ion cells performance, through novel test protocol for stationary applications (2017)

Renewable energy sources (RES) are changing the operating conditions of power systems. In this context, battery energy storage systems (BESSs) could be a viable technical solution to maximize the local consumption of RES generation or to provide ancillary services to the grid. However, the lack of technical information about the real field performance is affecting the diffusion of BESS on the market. Here we present a technological comparison between different lithium-based storage technologies in terms of energy density, power density and efficiency based on the IEC 62660-1 standard for automotive. However, the standard measurements are not sufficient to describe the cell performance in the case of stationary applications. We therefore introduce two additional test protocols to evaluate the energy density as a function of the power density, and the efficiency as a function of the charge/discharge current rates. We discuss how these procedures improve the evaluation of performance and how they improve the system design and cost estimation for BESS in stationary applications.
Meßabweichung, Meßunsicherheit, Meßgerätefähigkeit (1996)

Meßergebnisse sind nur dann miteinander vergleichbar, wenn sie unter reproduzierbaren Bedingungen gewonnen wurden. Durch Angabe von Referenzbedingungen soll ein Meßergebnis nachvollziehbar werden. Zu den Referenzbedingungen gehören die Bezugstemperatur, die nach DIN 102 auf 20 °C festgelegt ist, ferner der gesamte Meßablauf (Messung unter Wiederholbedingungen oder unter Vergleichsbedingungen) und die Einflußgrößen, die selbst nicht zur Meßgröße gehören, den Meßwert aber beeinflussen. Beim Messen geometrischer Größen sind die Temperaturen von Meßobjekt und Umgebung wichtige Einflußgrößen, die Meßabweichungen zur Folge haben können. Der Meßtechniker bemüht sich wohl, durch eine geeignete Meßanordnung, durch einen günstigen Meßablauf und Abschirmen von Störgrößen die Meßabweichungen klein zu halten, ganz vermeiden kann er sie jedoch nicht.
Compact isolation-enhanced UWB MIMO antenna with band-notch character (2016)

In this paper, a compact multiple-input multiple-output antenna with band-notched characteristic is presented for Ultra-Wideband (UWB) applications. Two orthogonally placed radiator elements excite the same open slot which consists of two connected T-shaped slots on the ground plane. Such orthogonal structure easily achieves good diversity performance. To enhance isolation of the lower band, a fork-shaped slot is notched on the ground between two radiators, and the mutual coupling reduces to −20 dB below for the entire UWB frequency band. By slitting open-ended quarter-wavelength L slots on the radiator elements, the rejection bands are achieved. The compact size of the antenna is only 30 × 30 mm2, and the antenna prototype is fabricated and measured. Measured results indicate that a wide-impedance bandwidth, which is from 2.85 to 11.9 GHz with rejection band of 5.1–6 GHz, is achieved, and the envelope correlation coefficient is below 0.008, which are competitive for portable UWB devices.
