There was a lack of difference in the accuracy of the various bacterial vaginosis tests for predicting preterm birth in both asymptomatic and symptomatic women of threatened preterm labour.
Car Size in U.K. Crashes: The Effects of User Characteristics, Impact Configuration, and the Patterns of Injury (2002)

Previous work examining the effect of vehicle mass has demonstrated the link with occupant injury severity. The principal factor has been related to Newtonian mechanics. This article analyses data from the U.K. Co-operative Crash Injury Study and identifies other factors associated with car size. The mass of the car is found to have a predominant effect on injury outcome in frontal collisions only where the effect is seen most in injuries to the head, face, and chest. Most fatal casualties in small cars occur when in collision with another car in front or side collisions while the key group for large cars is frontal collisions with roadside objects. There are several characteristics of small car occupants that differ from those in large cars including gender, age, and vehicle occupancy. New information in the analysis concerns the priorities in casualty reduction between small and large car occupants, and the article argues that vehicle design should take account of this variation to produce vehicles optimized for the complete range of crashes and car occupants.

Software-defined underwater acoustic networks: toward a high-rate real-time reconfigurable modem (2015)

We review and discuss the challenges of adopting software-defined radio principles in underwater acoustic networks, and propose a software-defined acoustic modem prototype based on commercial off-the-shelf components. We first review current SDR-based architectures for underwater acoustic communications. Then we describe the architecture of a new software-defined acoustic modem prototype, and provide performance evaluation results in both indoor (water tank) and outdoor (lake) environments. We present three experimental testbed scenarios that demonstrate the real-time reconfigurable capabilities of the proposed prototype and show that it exhibits favorable characteristics toward spectrally efficient cognitive underwater networks, and high data rate underwater acoustic links. Finally, we discuss open research challenges for the implementation of next-generation software-defined underwater acoustic networks.
Pro-Active Detection of Content Quality in TurboTax AnswerXchange (2015)

User satisfaction in social question-and-answer (Q&A) systems depends on the quality of answers typically measured by a proxy metrics of user votes on the answers. We show that user votes in TurboTax AnswerXchange (AXC) can be predicted with reasonable accuracy based on the attributes of the question alone. This provides an opportunity for "pro-active" detection of potentially high or low quality content in real time while the question is still being formulated. As a result, undesirable content can be prevented by instructing the user to re-phrase the question. We can also optimize the AXC answer queue or tweak the AXC point system to generate higher quality answers.
High-speed three-dimensional human retinal imaging by line-field spectral domain optical coherence tomography (2007)

Line-field spectral domain optical coherence tomography (LF-SDOCT) has been developed for very high-speed three-dimensional (3D) retinal imaging. By this technique, the A-line rate significantly improved to 823,200 A-lines/s for single frame imaging and 51,500 A-lines/s for continues frame imaging. The frame rate at continues frame imaging is 201 fps. This 3D acquisition speed is more than two fold higher acquisition speed than the standard flying spot SD-OCT. In this paper, the integration time of the camera was optimized for the in vivo retinal measurement and the degradation of the lateral resolution due to the ocular aberrations was suppressed by introducing the pupil stop. Owing to an optimal integration time, the motion artifact can be significantly suppressed. Also a pupil stop was employed in order to enhance the contrast of the OCT image for the effect of ocular aberrations. The in vivo 3D retinal imaging with 256 cross-sectional images (256 A-lines/image) was successfully performed in 1.3 seconds, corresponding to 0.8 volume/s. The maximum on-axis system sensitivity was measured to be 89.4 dB at a depth of 112 mum with an axial resolution of 7.4 mum in tissue. It is shown that LF-SDOCT might have a sensitivity advantage in comparison to the flying spot SD-OCT in the ultra high-speed acquisition mode.

Simple Aqueous Preparation of High Activity and Stability NiFe Hydrous Oxide Catalysts for Water Oxidation (2016)

A series of Ni1–xFex hydrous oxide nanoparticles (HO-nps, x = 0–0.5, 1) were prepared by stirring 0.1 M KOH solutions of NiCl2 and FeCl2 under air at room temperature. The resulting HO-nps can be used directly, or washed and isolated without loss of activity. The Ni1–xFex HO-nps are outstandingly active and stable toward the water oxidation reaction (WOR) in base. The Ni0.75Fe0.25 HO-np was the most active mass-normalized WOR catalyst in the series, with onset overpotential = 190 mV, Tafel slope = 24 mV dec–1, overpotential at 10 mA cm–2 = 234 mV, and loadings Ni + Fe = 0.135 mg cm–2. The catalysts were robust under long-term galvanostatic and duty-cycle testing. The Ni0.75Fe0.25 HO-np catalyst has a layered double hydroxide structure, and it appears that Fe enhances the activity of Ni toward the WOR by decreasing its electron density.
Oligonucleotides form a duplex with non-helical properties on a positively charged surface (2001)

The double helix is known to form as a result of hybridization of complementary nucleic acid strands in aqueous solution. In the helix the negatively charged phosphate groups of each nucleic acid strand are distributed helically on the outside of the duplex and are available for interaction with cationic groups. Cation-coated glass surfaces are now widely used in biotechnology, especially for covalent attachment of cDNAs and oligonucleotides as surface-bound probes on microarrays. These cationic surfaces can bind the nucleic acid backbone electrostatically through the phosphate moiety. Here we describe a simple method to fabricate DNA microarrays based upon adsorptive rather than covalent attachment of oligonucleotides to a positively charged surface. We show that such adsorbed oligonucleotide probes form a densely packed monolayer, which retains capacity for base pair-specific hybridization with a solution state DNA target strand to form the duplex. However, both strand dissociation kinetics and the rate of DNase digestion suggest, on symmetry grounds, that the target DNA binds to such adsorbed oligonucleotides to form a highly asymmetrical and unwound duplex. Thus, it is suggested that, at least on a charged surface, a non-helical DNA duplex can be the preferred structural isomer under standard biochemical conditions.
P11.59.B Real-life application of the 2021 WHO Classification molecular criteria in Italy: a national survey from the Italian Association of Neuro-Oncology (AINO) Gruppo Giovani (2022)

Abstract Background Diffuse gliomas display heterogeneous biology, natural history, response to treatments, and outcome. According to the 2021 WHO Classification, an integration of histological and molecular factors is needed for the diagnosis of diffuse gliomas. The Italian Association of Neuro-Oncology (AINO), with the participation of the Italian Society of Neurosurgery (SINch), promoted a survey to explore how the 2021 WHO molecular diagnostic criteria are integrated into clinical practice in a national framework. Material and Methods A web-based survey containing 38-item multiple-choice questions was sent to members of the AINO and SINch in February 2022 via the respective email listings of these organizations. Results We collected 152 answers. Most attendants were &amp;lt; 45-year-old (117, 77.0%). Participants from North, Centre and South of Italy were 85 (55.9%), 38 (25.0%), and 29 (19.1%). Academic and non-academic hospitals were 35 (46.1%) and 82 (53.9%). The presence of an institutional Brain Tumour Board was reported in 108 cases (71.7%). One hundred forty attendees (92.1%) reported that IDH mutation was assessed in all glioma patients regardless of age. The 1p19q-codeletion was assessed routinely in all IDH-mutant gliomas in 88 (57.9%) or when TP53 mutation and/or ATRX expression was found (45, 29.6%). The MGMTp methylation was assessed, regardless of grading, at diagnosis in 110 (72.4%), and at second surgery in 82 (53.9%). Eighty (52.6%) performed a quantitative analysis of MGMTp status. The CDKN2A/B homozygous deletion in IDH-mutant lower-grade astrocytomas was routinely investigated in 53 (34.9%). Assessment of EGFR amplification, pTERT status or +7/-10 chromosome alterations to stratify IDH-wildtype lower-grade astrocytomas was reported in 76 (50.0%), 43 (28.3%), and 16 (10.5%) cases. Rarer alterations were less commonly investigated (H3K27M: 34, 22.4%; H3G34: 11, 7.2%; BRAF: 18, 11.8%; NTRK: 16, 10.5%), being usually evaluated in selected cases (e.g., younger patients). Academic vs non-academic hospitals treated more patients per year (&amp;gt; 300 in 22/70, 31.4% vs 3/82, 3.7%, p&amp;lt;0.001), had more available molecular technologies (53/70, 75.5% vs 37/82, 45.1, p&amp;lt;0.001), had a higher availability of molecular markers, such as CDKN2A/B deletion (34/70, 48.6% vs 19/82, 23.2%, p=0.001), MGMTp at second surgery (48/69, 69.6% vs 34/72, 47.2%, p=0.008), EGFR/pTERT/+7-10 (46/70, 65.7% vs 32/77, 41.6%, p=0.003), BRAF (14/70, 20.0% vs 4/82, 4.9%, p=0.002), NTRK (14/70, 20.0% vs 2/81, 2.5%, p&amp;lt;0.001). Conclusion The availability of new molecular markers is increasing among Italian Neuro-Oncology Centres. However, there is still a gap with the proposed criteria of the 2021 WHO Classification and the real-life application. A critical issue remains how to select patients who might benefit from the identification of some extremely rare mutations in light of targeted therapies.
Dyakonov–Tamm waves guided by the planar surface of a chiral sculptured thin film (2013)

Propagation of Dyakonov&#x2013;Tamm waves guided by the interface of air and a chiral sculptured thin film (STF) was investigated theoretically. The solution of the dispersion equation showed that the direction of propagation is either unrestricted or almost unrestricted in the interface plane. For very limited ranges of the direction of propagation, multiple Dyakonov&#x2013;Tamm waves may even exist. These surface waves were theoretically found to be excitable in the Otto prism-coupled configuration by an incident plane wave of either linear polarization state, thereby lending hope for an easy way to observe Dyakonov&#x2013;Tamm waves experimentally.

Broadband Island interconnection via satellite—performance analysis for the race II—catalyst project (1994)

Abstract The use of communication satellites as a possible way of offering broadband island interconnectivity appears to be a very attractive option, as it will enable the provision of an all‐digital, transparent service to a number of ATM islands spanning a wide area, accommodating efficiently a variety of traffic demands. The CATALYST Project (RACE II/R2074) is an attempt to demonstrate the applicability and compatibility of satellite technology with the terrestrial BISDN. In this paper we present an overview of the project and focus on an initial study of the expected user performance through the CATALYST network. Our analysis is based upon mathematical and simulation models and describes the end‐system to end‐system transfer delay for given message lengths. The protocol profiles assume a mix of Novell NetWare and Network File System client/server architectures, which are supported by either the IEEE 802.3/Ethernet or fibre distributed data interface LANs, which are themselves linked via LAN/ATM/satellite interface units. Areas of further investigation, and the implication of our analysis on the actual network architecture, are discussed.
Gold-layered calcium phosphate plasmonic resonants for localized photothermal treatment of human epithelial cancer (2009)

We fabricated de novo biocompatible mineral plasmon resonants for localized and systemic treatment of cancer. Biodegradable calcium-phosphate gold nanocomposites were synthesized for inducing a superior surface plasmon resonance effect. The combination of therapeutic antibody, Erbitux® and NIR laser with nanocomposites demonstrated the potential for selective bimodal cancer treatment by combination of EGFR-induced signaling inhibition as a systemic treatment and localized photothermal effects caused by the NIR laser.

Adducts of nitrogenous ligands with rhodium(II) tetracarboxylates and tetraformamidinate: NMR spectroscopy and density functional theory calculations (2013)

Complexation of tetrakis(μ2-N,N'-diphenylformamidinato-N,N')-di-rhodium(II) with ligands containing nitrile, isonitrile, amine, hydroxyl, sulfhydryl, isocyanate, and isothiocyanate functional groups has been studied in liquid and solid phases using (1)H, (13)C and (15)N NMR, (13)C and (15)N cross polarisation-magic angle spinning NMR, and absorption spectroscopy in the visible range. The complexation was monitored using various NMR physicochemical parameters, such as chemical shifts, longitudinal relaxation times T1 , and NOE enhancements. Rhodium(II) tetraformamidinate selectively bonded only unbranched amine (propan-1-amine), pentanenitrile, and (1-isocyanoethyl)benzene. No complexation occurred in the case of ligands having hydroxyl, sulfhydryl, isocyanate, and isothiocyanate functional groups, and more expanded amine molecules such as butan-2-amine and 1-azabicyclo[2.2.2]octane. Such features were opposite to those observed in rhodium(II) tetracarboxylates, forming adducts with all kind of ligands. Special attention was focused on the analysis of Δδ parameters, defined as a chemical shift difference between signal in adduct and corresponding signal in free ligand. In the case of (1)H NMR, Δδ values were either negative in adducts of rhodium(II) tetraformamidinate or positive in adducts of rhodium(II) tetracarboxylates. Experimental findings were supported by density functional theory molecular modelling and gauge independent atomic orbitals chemical shift calculations. The calculation of chemical shifts combined with scaling procedure allowed to reproduce qualitatively Δδ parameters.

Purification of Silicon by Directional Solidification (1997)

Purification of silicon by directional solidification under the solidification rate from 5.9×10−6 to 2.2×10−5 m/s was applied for removing aluminium, iron and titanium. Aluminium content was decrease of up to the range of two to three orders from about 100 mass ppm. Iron and titanium contents were decreased under 0.1 mass ppm from about 300 and 20 mass ppm, respectively. Aluminium content profile in solidified silicon could be expressed by the Sceil’s equation and Burton’s equation. Iron and titanium content profiles could not be confirmed by those equations, because detective values limit for iron and titanium were higher than the calculated content.High initial impurity contents lowered efficiency for removing impurity contents in silicon. This was assumed that the stability of planar solid/liquid interface was broken by a low temperature gradient of the liquid phase according to the constitutional supercooling theory.SOG-Si which was experimentally produced through the direct reduction process and the molten purification process showed low impurities contents of less than 0.1 mass ppm of aluminium, iron and titanium. Conversion efficiency of the multicrystalline cell made by those silicon had almost the same performance as made from electrical-grade silicon.

Speckle interferometry for non destructive testing of out of plane or in-plane stresses or deformations of rough mechanical parts is a powerful and modern technique. Basics of speckle phenomena and interferometry in specked light are reviewed. Electronic speckle pattern interferometry for vibration analysis and a Duffy-Young digital camera for in- plane measurement are presented.
Comparative study of vibro-acoustography and B-mode ultrasound in prostate imaging (2008)

Vibro-acoustography (VA) is an imaging modality that uses the radiation force of ultrasound to vibrate tissue at a low frequency and records the resulting acoustic field to produce an image that is represents object characteristics at both ultrasound as well as low (audio) frequencies. Currently, B-mode ultrasound is used for prostate imaging. This imaging method has some limitations, including the speckle noise, which limit its ability in detection of lesions and calcifications. The purpose of this study is to explore the potentials of VA for prostate imaging. VA, B-mode ultrasound, and radiography were performed on 12 excised human prostate samples and the resulting images were compared. VA system parameters were, center frequency 3 MHz, Δf=50 kHz, image area 5×5 cm, pixel size 0.2×0.2 mm. Images evaluated in terms of visibility of anatomical and pathological structures and contrast. Results showed that prostate anatomical structures, mass lesions, and calcifications were visible in the VA images taken at different depths, and VA image quality was superior to B-mode. VA images exhibited significant contrast between the central and peripheral zones with enhanced borders. It is concluded that, with further development, VA may become suitable modality for in prostate imaging.
