SOUND SOURCE LOCATION MEASUREMENTS ON HIGH SPEED TRAINS (1979)

Measurements with two different directional microphone systems were made for the purpose of locating and identifying radiated noise sources on a high speed electric train travelling at speeds between 160 and 250 km/h. An acoustic mirror with 7 microphones positioned in the focal plane was used to measure higher frequency noise, while a linear array of 14 microphones was used for lower frequencies. Data recorded with the array were processed so as to allow the main lobe to either (1) focus dead ahead, or (2) be electronically slewed to track moving sound sources. Both wheel/rail and aerodynamic sound sources were investigated with the mirror and the array. The results of these measurements demonstrate the versatility and usefulness of directional microphone systems for locating and analyzing noise sources on moving vehicles.
[Initial observations on the biocompatibility of a polymer used as a skin dressing]. (1983)

In the development of a dressing for burn wound covers, a material is required which combines good oxygen permeability, high water content and good biocompatibility with reasonable mechanical properties. One of the most important functions of the cover is to protect the burned surfaces from drying out and to constitute the first defence against microbial invasion. In this study composite sheets crosslinked either in presence of glicerol or diacetin, obtained by reinforcing PHEMA with a tricot PET net have been implanted subacute in rabbits, to test their biocompatibility. The same composites crosslinked in presence of diacetin and grafted on a polybutadene film, have been used as a skin graft on rabbits.
(Invited) Microdefects in Czochralski-Grown Silicon Crystals and Their Application to Gettering Technique (1982)

Microdefects in Czochralski-grown (CZ) silicon crystals are induced by thermal treatments used in an LSI process. They are detrimental to device performance, if they are formed near the surface. The microdefects originate in the precipitation of oxygen involved in CZ crystals. However, it is possible to reduce the microdefect density after thermal treatments without decreasing the oxygen concentration by controlling crystal growth condition. On the other hand, the microdefects serve as gettering sites for both harmful impurities and surface defects, if their formations are confined to the interior of the wafer. This is called the intrinsic gettering (I-G) phenomenon. The I-G technique is successfully applied to a lifetime improvement, a heavy metal gettering, and an elimination of surface defects.
Charts for Resonant Frequencies of Cavities (1947)

Six charts are given which may be used for designing cylindrical resonant cavities whose cross sections are circles, concentric circles, squares, or rectangles. A new method of representing multiple-resonance phenomena is used, to which the name "mode lattice" has been given. The mode lattice is an alignment chart which relates the size and shape of a cavity with resonant wavelength for a large number of modes. Points distributed on a lattice represent the modes. The equations involved, the method of use, and the special advantages of each chart are described, together with the method of construction. A set of equations has been derived for calculating the effect of small changes in dimensions or wavelength for resonators of all the above shapes.
Capacity Degradation Mechanism and Cycling Stability Enhancement of AlF<sub>3</sub>-Coated Nanorod Gradient Na[Ni<sub>0.65</sub>Co<sub>0.08</sub>Mn<sub>0.27</sub>]O<sub>2</sub> Cathode for Sodium-Ion Batteries (2018)

O3-type Na[Ni <sub>x</sub>Co <sub>y</sub>Mn <sub>z</sub>]O<sub>2</sub> materials are attractive cathodes for sodium-ion batteries because of their full cell fabrication practicality, high energy density, and relatively easy technology transfer arising from their similarity to Li[Ni <sub>x</sub>Co <sub>y</sub>Mn <sub>z</sub>]O<sub>2</sub> materials, yet their performance viability with Ni-rich composition ( x ≥ 0.6) is still doubtful. More importantly, their capacity degradation mechanism remains to be established. In this paper, we introduce an O3-type Ni-rich AlF<sub>3</sub>-coated nanorod gradient Na[Ni<sub>0.65</sub>Co<sub>0.08</sub>Mn<sub>0.27</sub>]O<sub>2</sub> cathode with enhanced electrochemical performance in both half-cells and full cells. AlF<sub>3</sub>-coated nanorod gradient Na[Ni<sub>0.65</sub>Co<sub>0.08</sub>Mn<sub>0.27</sub>]O<sub>2</sub> particles were synthesized through a combination of dry ball-mill coating and columnar composition gradient design and deliver a discharge capacity of 168 mAh g<sup>-1</sup> with 90% capacity retention in half cells (50 cycles) and 132 mAh g<sup>-1</sup> with 90% capacity retention in full cells (200 cycles) at 75 mA g<sup>-1</sup> (0.5C, 1.5-4.1 V). Through analysis of the cycled electrodes, the capacity-degradation mechanism was unraveled in O3-type Ni-rich Na[Ni <sub>x</sub>Co <sub>y</sub>Mn <sub>z</sub>]O<sub>2</sub> from a structural perspective with emphasis on high-resolution transmission electron microscopy, providing valuable information on improving O3-type Na[Ni <sub>x</sub>Co <sub>y</sub>Mn <sub>z</sub>]O<sub>2</sub> cathode performance.
Test of a stand-off laser-induced breakdown spectroscopy sensor for the detection of explosive residues on solid surfaces (2005)

The detection and characterization of energetic materials at distances up to 45 m using stand-off laser induced breakdown spectroscopy (LIBS) has been demonstrated. A field-portable open-path LIB spectrometer working under a coaxial configuration was used. A preliminary study allowed choosing a single-pulse laser source over a double-pulse system as the most suitable source for the stand-off analysis of organic samples. The C2 Swan system, as well as the hydrogen, oxygen and nitrogen emission intensity ratios were the necessary parameters to identify the analyte as an organic explosive, organic non-explosive and non-organic samples. O/N intensity ratios of 2.9 and 2.16 with relative standard deviations of 4.03% and 8.36% were obtained for 2,4-dinitrotoluene and aluminium samples, respectively. A field test with known samples and a blind test were carried out at a distance of 30 m from the sample. Identification of energetic compounds in such conditions resulted in 19 correct results out of 21 samples.
Minimum time path planning for robot motion in obstacle strewn environment (1986)

A new algorithm of minimum time motion planning is proposed for robots operating in the obstacle strewn environment. Structure of the topological passageways is analyzed and represented using a model of slalom situations for which a number of rules is determined. Dynamical system of robot is described in a form of sequential machine. Thls enabled a merger between two kindred algorithms: A* search algorithm, and dynamic programming. An experimental analysis of the simulated mobile robot has confirmed the applicability of results.
64 pH-ISFET averaging array employing global negative current feedback (2009)

The previously reported discrete ISFET using current feedback has been redesigned in a CMOS platform with an array of ISFETs to improve the performance of the single ISFET's readout. The circuit novelty is the averaging of ISFET currents generated by a cluster of 64 ISFETs with a global current feedback. Simulation results from the 0.18 µm CMOS process also indicate improvements of high signal-to-noise ratio with power consumption to early µW. As a result, it all leads to benefit biomedical applications.
A Chorionic Gonadotropin-Secreting Human Pituitary Cell* (1991)

Recent data from our laboratory show that hCG is secreted in a pulsatile manner in parallel with human LH (hLH) in nonpregnant normal humans. Furthermore, GnRH stimulates hCG and hLH release. Using a monoclonal antibody specific for the beta-chain of hCG and not reacting with hLH, we have identified a heretofore unknown cell type in human pituitaries which stains only for hCG. The light microscopic, immunocytochemical, and ultrastructural features are described. These data coupled to those from multiple earlier studies indicate that hCG is secreted by these cells in normal nonpregnant humans.
The handing over of foundlings in the early XIX century: an unpublished study on the medical and social problems of newborn babies abandoned in the hospital of Città di Castello. (1990)

The problems of illegitimate births in the early XIX century. The newborn babies were abandoned at the "Rota" of the hospital. The handing over of the newborn babies to the Rota avoided their being left with unknown persons, who, attracted by infant cries from a bundle in front of a Church or Convent, might be unreliable though compassionate. The hospital was the safest place for the babies as it provided immediate care but only after their souls had been given priority. First baptism and then medical care. For concealment the parents' names were not revealed. The baby was handed over by friends or well-wishers, a midwife or a neighbour that took interest in the baby receiving the required attention.

Antibody Activity in Otitis Media with Effusion (1979)

Bacteria were isolated from a high percentage of the effusions from patients with otitis media with effusion (OME, serous otitis media). In an attempt to determine if the isolated bacteria were involved in the disease process, we analyzed the serum and effusion of 25 OME patients for the presence of antibacterial antibodies by the indirect immunofluorescence antibody method. Specific antibody activity was detected in 20 of 25 effusions (80%) and 19 of 22 sera (86%). IgG antibodies were the most frequently found class of antibodies in both sera and effusions, but IgA antibodies were detected more frequently in the effusions than in the sera. Hemophilus influenzae, Streptococcus pneumoniae, and diphtheroids were the most frequently isolated organisms, and antibody activity to all bacterial species isolated was detected. The results support the concept that the isolated bacteria are not contaminants but are actively involved in the disease process.

Total Stepwise Solid-Phase Peptide-Oligonucleotide Conjugate Synthesis on Macroporous Polystyrene (2003)

An efficient total stepwise solid-phase synthesis of oligonucleotide-peptide conjugates on a macroporous polystyrene is described. Extending our homoserine linker approach, we prepared a range of fluorescein-labelled conjugates containing one of two different peptides together with oligonucleotides containing 2'-deoxynucleoside or 2'-O-methylribonucleoside phosphodiesters, or gapmers containing 2'-deoxyphosphorothioate sequences flanked by 2'-O-methyl wings.
High-power self-starting femtosecond Cr:forsterite laser (1998)

Owing to its broad tunability and useful fundamental and second harmonic wavelengths, Cr:forsterite (Cr 4+ :Mg 2 SiO 4 ) lasers are attracting a lot of attention in the ultrafast science. However, self-starting operation of relatively low power Kerr lens mode-locked femtosecond Crforsterite lasers using semiconductor saturable-absorber mirrors (SESAM’s) was reported only recently [1,2]. We scaled the parameters of this purely passive technique and achieved simultaneously output energies on the 10-nJ level and sub-100 fs pulse durations. The high contrast of these pulses allowed for the first time efficient direct frequency conversion to the 600 nm region with efficiency as high as 30%.
High-temperature MIRAGE XL (LFRA) IRSP system development (2017)

The development of very-large format infrared detector arrays has challenged the IR scene projector community to develop larger-format infrared emitter arrays. Many scene projector applications also require much higher simulated temperatures than can be generated with current technology. This paper will present an overview of resistive emitterbased (broadband) IR scene projector system development, as well as describe recent progress in emitter materials and pixel designs applicable for legacy MIRAGE XL Systems to achieve apparent temperatures >1000K in the MWIR. These new high temperature MIRAGE XL (LFRA) Digital Emitter Engines (DEE) will be “plug and play” equivalent with legacy MIRAGE XL DEEs, the rest of the system is reusable. Under the High Temperature Dynamic Resistive Array (HDRA) development program, Santa Barbara Infrared Inc. (SBIR) is developing a new infrared scene projector architecture capable of producing both very large format (>2k x 2k) resistive emitter arrays and improved emitter pixel technology capable of simulating very high apparent temperatures. During earlier phases of the program, SBIR demonstrated materials with MWIR apparent temperatures in excess of 1500 K. These new emitter materials can be utilized with legacy RIICs to produce pixels that can achieve 7X the radiance of the legacy systems with low cost and low risk. A 'scalable' Read-In Integrated Circuit (RIIC) is also being developed under the same HDRA program to drive the high temperature pixels. This RIIC will utilize through-silicon via (TSV) and Quilt Packaging (QP) technologies to allow seamless tiling of multiple chips to fabricate very large arrays, and thus overcome the yield limitations inherent in large-scale integrated circuits. These quilted arrays can be fabricated in any N x M size in 512 steps.
Reactions of organosulphur ligands on tungsten centres. Evidence for carbonium ion formation in the degradation of alkanethiolatopentachlorotungsten(VI) species (1980)

The monothiolate derivatives of tungsten(VI) chloride, [WCl5(SR)](R = Me, Et, cyclohexyl, But, But, CH2,Ph, or Ph), have been found to be unstable with respect to at least two modes of degradation. Heterolytic cleavage of the carbon–sulphur bond to generate a carbonium ion, which can further abstract chloride to give WSCl4+ RCl, is the preferred pathway if the R+ ion is relatively stable. The intermolecular elimination of R2S2 is the alternative route for degradation and is the exclusive one for R = Ph, where the carbonium ion is very unstable. The only pure [WCl5(SR)] compounds which have been isolated are [WCl5(SMe)] and [WCl5(SPh)] and even these slowly decompose at room temperature over a period of a few weeks.
Study on friction behavior of SiC-B<sub>4</sub>C composite ceramics after annealing (2019)

Purpose This study aims to investigate the friction behavior of SiC-B 4 C composite ceramics treated by annealing in air sliding against SiC balls. Design/methodology/approach The dry sliding tests were performed with a ball-on-disk tribometer in ambient air condition. Analysis of friction coefficient, phase compositions of the surfaces, morphologies of worn surfaces of disks and wear scars of balls and surface profiles of wear tracks for disks were carried out using Raman spectroscope, microscope and surface profilometer. Findings The results show that a self-lubricating layer with the main composition of H 3 BO 3 was successfully fabricated on the surface of SiC-B 4 C composite ceramics by the annealing treatment in air. When the mass fraction of SiC is more than that of B 4 C, SiC-B 4 C composite ceramics show higher friction coefficients, the values of which are 0.38 for 80 Wt.%SiC-20 Wt.%B 4 C and 0.72 for 60 Wt.%SiC-40 Wt.%B 4 C, respectively. SiC-B 4 C composite ceramics show lower friction coefficients when the mass fraction of B 4 C is more than that of SiC. The low friction coefficients of 40 Wt.%SiC-60 Wt.% B 4 C composite ceramics (0.16) and 20 Wt.%SiC-80 Wt.% B 4 C composite ceramics (0.20) are attributed to the formation of a sufficient amount of H 3 BO 3 layer, rather than the layer of silicon oxides. Originality/value This study will help to understand the friction behavior of SiC-B 4 C composite ceramics with different ratios of SiC to B 4 C treated by annealing in air.
Action Bank: A High Level Representation of Activity in Video (Author's Manuscript) (2012)

Abstract : Activity recognition in video is dominated by low- and mid-level features, and while demonstrably capable, by nature, these features carry little semantic meaning. Inspired by the recent object bank approach to image representation, we present Action Bank, a new high-level representation of video. Action bank is comprised of many individual action detectors sampled broadly in semantic space as well as viewpoint space. Our representation is constructed to be semantically rich and even when paired with simple linear SVM classifiers is capable of highly discriminative performance. We have tested action bank on four major activity recognition benchmarks. In all cases, our performance is better than the state of the art, namely 98.2 on KTH (better by 3.3 ), 95.0 on UCF Sports (better by 3.7 ), 57.9 on UCF50 (baseline is 47.9 ), and 26.9 on HMDB51 (baseline is 23.2 ). Furthermore, when we analyze the classifiers, we find strong transfer of semantics from the constituent action detectors to the bank classifier.
Decoupling Thin Film CdTe Growth from Packaging: Toward Record Specific Power in Low Cost Polycrystalline PV: Preprint (2018)

There are critical material and scientific barriers to producing high efficiency, flexible, lightweight solar cells that maximize specific power in a cost-effective manner. GaAs solar cells produce the highest specific power of any photovoltaic (PV) technology due to their low weight and extremely high efficiency, but they are also among the most expensive to produce. This work explores a novel lift-off approach with thin-film solar cells, particularly CdTe, to achieve high specific power at low costs. Thin-film devices can be delaminated from their heavy, glass growth substrates post-growth by exploiting a mismatch in coefficient of thermal expansion between the two. This allows thin-film PV to be decoupled from high temperature growth requirements and repackaged using lightweight materials. Currently, the most consistent method of achieving complete delamination of CdTe films is to apply a glass handle at the back contact of the device using epoxy and submerge it in liquid nitrogen. By Tthen re-depositing a transparent front contact but be re-deposited and selectively etcheding to expose the back contact to produce, a functioning lifted-off devices have been produced. Effects of delamination and contributions to device functionality from CdCl2 and CdS layers are discussed. Reproducible delamination of high efficiency, thin-film solar cells over large areas will enable work to further improve device efficiency through passivation and reconstruction of the previously buried interface between the transparent contact and CdS.
Epidural block (2012)

Abstract Epidural block has now become well established as an adjunct to general anaesthesia and is regarded as the most effective means of providing pain relief after surgery and during labour (Dolin et al. 2002). Regardless of the type of surgery and means of assessing pain, epidural block provides better pain relief than parenteral opioids (Block et al. 2003). Several factors have contributed to this: 1. Placement of a catheter in the epidural space is a relatively straightforward procedure; 2. Epidural block may be extended for several days into the postoperative period if needed; 3. Quality pain relief allows effective coughing and early mobilization; and 4. Acute pain teams are available to provide continuity of management. There are, however, disadvantages: 1. Visceral sensation remains intact and general anaesthesia is needed as a supplement for major surgery of the thorax and abdomen; 2. Surgery to the trunk requires thoracic epidural block, but inexperienced anaesthetists tend to insert catheters several dermatomes below the ideal, ‘mid-incisional’ level, resulting in inadequate pain relief and lower limb motor block; 3. Performance of the block adds to anaesthesia time; and 4. Pre-existing neurological conditions, coagulation disorders, and pharmacological thromboprophylaxis are weightier contraindications to epidural block than to other regional techniques because bleeding into the epidural space is not always immediately apparent, cannot be controlled directly, and may only be revealed when it causes symptoms.
