An area-efficient VLSI architecture of a Reed-Solomon decoder/encoder for digital VCRs (1997)

A new flexible and area-efficient VLSI architecture of a Reed-Solomon product-code decoder/encoder has been developed for digital VCRs. The new architecture of the decoder/encoder targeted to reduce the circuit size and decoding latency has the following three features. First, a high area-efficiency has been achieved by sharing a functional block for encoding, modified syndrome computation, and erasure locator polynomial evaluation. Second, the circuit size and decoding latency has been reduced by using a new architecture to implement the modified Euclid's algorithm. Third, by doubling the internal clock speed (from 18 MHz to 36 MHz), the decoding latency and hence the memory size can be reduced. The decoder/encoder designed by using the proposed method uses a reduced number of gates, by about 30%, than the one based on the conventional architectures.
Purification of a β-Primeverosidase Concerned with Alcoholic Aroma Formation in Tea Leaves (Cv. Shuixian) To Be Processed to Oolong Tea (1997)

β-Primeverosidase, which is concerned with the alcoholic aroma formation in tea leaves, was purified from fresh tea leaves (Camellia sinensis var. sinensis cv. Shuixian) to be processed to oolong tea by successive precipitation with acetone and ammonium sulfate followed by column chromatography on CM-Toyopearl and Mono S-HR. The molecular mass was shown to be 61 and 60.3 kDa by SDS−PAGE and TOFMS, respectively. Its pI, optimum temperature, and pH are 9.5, 45 °C, and 4, respectively. The enzyme is stable below 45 °C and between pH 3 and 5. The enzyme hydrolyzes β-primeveroside into primeverose and an aglycon without further hydrolysis. These enzymic characteristics were found to be quite similar to those of the β-primeverosidase from cv. Yabukita exclusively processed to green tea. As most of the alcoholic tea aroma precursors have been isolated as β-primeverosides, the main route of the aroma formation in oolong tea has been elucidated on a molecular basis. Keywords: β-Primeverosidase; oolong tea; Camellia sinensis; aroma formation; glycosidase; tea aroma
"Maneggiare con cura" : un rapporto sulla redazione delle Buone Pratiche per la storia orale (2017)

Nell’aprile 2014 l’Associazione italiana di storia orale (Aiso) diede incarico a una commissione – composta da sette storici e storiche, due giuristi e uno studioso di archivistica – di definire le «linee guida» per la pratica della storia orale. I lavori sono durati venti mesi e hanno portato all’approvazione nel novembre 2015 di un testo chiamato "Buone pratiche per la storia orale", che rappresenta il primo documento prodotto dalla comunità scientifica degli storici italiani teso a sciogliere i nodi di ordine etico, deontologico e giuridico che i ricercatori di storia si trovano ad affrontare quando utilizzano le fonti orali.\nIn questo articolo, tre componenti del gruppo di lavoro che ha elaborato le Buone pratiche intendono richiamare il contesto entro cui questo documento ha visto la luce per poi illustrarne le ragioni, i principi ispiratori, i destinatari, la procedura attraverso cui è stato redatto e gli esiti cui si è giunti.
Preparation and electrical properties of electrospun tin-doped indium oxide nanowires (2007)

Well-aligned tin-doped indium (ITO) nanowires have been prepared using the electrospinning process. The Sn doping mechanism and microstructure have been characterized by x-ray diffraction (XRD) and x-ray photoelectron spectroscopy (XPS). Devices for I-V measurement and field-effect transistors (FETs) were assembled using ITO nanowires with top contact configurations. The effect of Sn doping on the electrical conductivity was significant in that it enhanced the conductance by over 10(7) times, up to ∼1 S cm(-1) for ITO nanowires with an Sn content of 17.5 at.%. The nanowire FETs were operated in the depletion mode with an electron mobility of up to 0.45 cm(2) V(-1) s(-1) and an on/off ratio of 10(3).
Optimizing sparse matrix-vector multiplication using index and value compression (2008)

Previous research work has identified memory bandwidth as the main bottleneck of the ubiquitous Sparse Matrix-Vector Multiplication kernel. To attack this problem, we aim at reducing the overall data volume of the algorithm. Typical sparse matrix representation schemes store only the non-zero elements of the matrix and employ additional indexing information to properly iterate over these elements. In this paper we propose two distinct compression methods targeting index and numerical values respectively. We perform a set of experiments on a large real-world matrix set and demonstrate that the index compression method can be applied successfully to a wide range of matrices. Moreover, the value compression method is able to achieve impressive speedups in a more limited yet important class of sparse matrices that contain a small number of distinct values
Exploring natural silk protein sericin for regenerative medicine: an injectable, photoluminescent, cell-adhesive 3D hydrogel (2014)

Sericin, a major component of silk, has a long history of being discarded as a waste during silk processing. The value of sericin for tissue engineering is underestimated and its potential application in regenerative medicine has just begun to be explored. Here we report the successful fabrication and characterization of a covalently-crosslinked 3D pure sericin hydrogel for delivery of cells and drugs. This hydrogel is injectable, permitting its implantation through minimally invasive approaches. Notably, this hydrogel is found to exhibit photoluminescence, enabling bioimaging and in vivo tracking. Moreover, this hydrogel system possesses excellent cell-adhesive capability, effectively promoting cell attachment, proliferation and long-term survival of various types of cells. Further, the sericin hydrogel releases bioactive reagents in a sustained manner. Additionally, this hydrogel demonstrates good elasticity, high porosity, and pH-dependent degradation dynamics, which are advantageous for this sericin hydrogel to serve as a delivery vehicle for cells and therapeutic drugs. With all these unique features, it is expected that this sericin hydrogel will have wide utility in the areas of tissue engineering and regenerative medicine.
The Single-Case Reporting Guideline In BEhavioural Interventions (SCRIBE) 2016: Explanation and elaboration. (2016)

Single-case experimental design (SCED) studies in the behavioral sciences literature are not only common, but their proportion has also increased over past decades. Moreover, methodological complexity of SCEDs and sophistication in the techniques used to analyze SCED data has increased apace. Yet recent reviews of the behavioral sciences literature have shown that reporting of SCED research is highly variable and often incomplete. Explicit, precise and transparent reporting is crucial not only for critical evaluation of the study methodology and conclusions, but also to facilitate exact replication of investigations, and ascertain applicability and possible generality of results. Accordingly, we developed the SCRIBE 2016 (Single-Case Reporting guideline In BEhavioural interventions) by a consensus process by experts in SCED methodology and research in the behavioral sciences, as well as experts in reporting guideline development. The SCRIBE 2016 Explanation and Elaboration article describes a set of 26 items to guide and structure the reporting of SCED research. A rationale and minimum reporting standards that stipulate what needs to be reported are provided for each item. In addition, examples of adequate and clear reporting drawn from the literature are included for each item. It is recommended that the SCRIBE 2016 Explanation and Elaboration article is used in conjunction with the complementary SCRIBE 2016 Statement (Tate et al., 2016) by authors preparing manuscripts for publication and journal reviewers and editors considering manuscripts for publication.
Mesoporous-silica films, fibers, and powders by evaporation (2023)

This invention pertains to surfactant-templated nanometer-scale porosity of a silica precursor solution and forming a mesoporous material by first forming the silica precursor solution into a preform having a high surface area to volume ratio, then rapid drying or evaporating a solvent from the silica precursor solution. The mesoporous material may be in any geometric form, but is preferably in the form of a film, fiber, powder or combinations thereof. The rapid drying or evaporation of solvent from the solution is accomplished by layer thinning, for example spin casting, liquid drawing, and liquid spraying respectively. Production of a film is by layer thinning, wherein a layer of the silica precursor solution is formed on a surface followed by removal of an amount of the silica precursor solution and leaving a geometrically thinner layer of the silica precursor solution from which the solvent quickly escapes via evaporation. Layer thinning may be by any method including but not limited to squeegeeing and/or spin casting. In powder formation by spray drying, the same conditions of fast drying exists as in spin-casting (as well as in fiber spinning) because of the high surface-area to volume ratio of the product. When a powder is produced by liquid spraying, the particles or micro-bubbles within the powder are hollow spheres with walls composed of mesoporous silica. Mesoporous fiber formation starts with a similar silica precursor solution but with an added pre-polymer making a pituitous mixture that is drawn into a thin strand from which solvent is evaporated leaving the mesoporous fiber(s).

A new grid-connected PV system based on cascaded H-bridge quasi-Z source inverter (2012)

A new scheme for grid-connected photovoltaic (PV) interface by combination of a quasi-Z source inverter (qZSI) into cascaded H-bridge (CHB) is proposed in this paper. The proposed scheme enables PV string voltage boost to a higher level, and solves the imbalance problem of DC-link voltage in traditional CHB inverters. A multilevel voltage waveform of inverter output is generated by an improved phase shifted sinusoidal pulse width modulation (PS-SPWM) algorithm, which introduces shoot-through states into the conventional zero states to control qZS-CHB module. The effective control schemes are proposed to regulate the maximum power point tracking (MPPT) of each string, and control the DC-link voltage of each H-bridge, respectively. Grid injected power is controlled corresponding to the proportionality factors of each PV string output power. A 1.5 kW system is built in MATLAB/SIMULINK, and the simulation results verify the proposed novel multilevel PV interface inverter and its control principles.
<title>Image registration for multifocus image fusion</title> (2001)

In this paper, some image registration algorithms are investigated for the purpose of image fusion. A hybrid scheme which uses both feature-based and intensity-based methods is proposed. In this scheme, an edge-based image registration approach is developed to guide the intensity- based registration which uses optical flow estimation. The idea of coarse-to-fine multiscale iterative refinement is also studied. Experiments show that this approach is robust and efficient.
Moco Mojo: Crystal Structure Reveals Essential Features of Eukaryotic Assimilatory Nitrate Reduction (2005)

Ankle arthrodesis using internal screw fixation. (1991)

Ankle arthrodesis treated by external fixation frequently results in complications from pin tract infections, loss of position, nonunion, and malunion. A method of ankle arthrodesis using 6.5-mm cancellous screws as the primary fixation hardware was developed. The most important screw is placed from the posterior malleolus into the neck and head of the talus, and medial and lateral malleolar screws are added to secure fixation. Near-normal anatomy is maintained with this technique because little or no bone, only cartilage, is removed. Earlier cases were all done through an anterior approach. Later, special techniques were developed for placing screws and strain-relieving bone grafting was added to promote union. Twenty-three cases that were treated by the earlier technique are reviewed. The overall fusion rate was 74%. Three conditions (avascular talus, pyarthrosis, and spasticity) were identified that placed patients at high risk for failure of fusion. Of the patients who were not in a high-risk group, only one had a delayed union. When the high-risk patients were not included in the statistics, the fusion rate was 93%. The evolved technique shows great promise for accurate and trouble-free ankle arthrodesis.
Study of Polymer Particles Suspensions for Electrophoretic Deposition (2012)

Recently a great interest has been expressed in electrophoretic deposition (EPD) of polymers, both as particles and as chains. It is generally accepted that also for polymer particles, the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory is valid, therefore, in principle, polymer suspensions suitable for EPD could be easily obtained by dispersing polymer particles in an aqueous or nonaqueous medium. Nevertheless, this work demonstrated that in order to obtain good quality deposits based on poly(ether ether ketone) (PEEK) and poly(tetrafluoroethylene) (PTFE), some additives have to be used. In the case of PEEK, a dispersant providing citrate anions was successfully used, whereas for PTFE a steric suspension stabilization was reached by adding polyvinylpyrrolidone (PVP). In such a way, codeposition of PEEK and PTFE was achieved. The efficiency of the EPD process was demonstrated by means of differential scanning calorimetry (DSC) measurements. A thermal program consisting of heat/cool/heat cycles at a low rate was used in order to evaluate the crystalline amount of each polymer in the deposits. In order to explain the obtained results, it needed to also consider the dimension and structural characteristic of the polymer particles.
A Simple Apparatus for Accelerating Recovery from Inhaled Volatile Anesthetics (2001)

High yield GaAs flip-chip MMICs lead to low cost T/R modules (2002)

A flip-chip design and assembly technique has been developed for GaAs MMICs resulting in lower fabrication costs and improved module yields. Plated bumps on the face of the MMIC are used as a replacement for wirebonds to interconnect all DC and RF signals. Wafer thinning, backside via etch, and backside plating steps have been eliminated, resulting in both higher fabrication yields and improved assembly yields. Microstrip matching networks have been replaced with uniplanar transmission structures such as Coplanar Waveguide (CPW) and spiral inductors. RF data will be shown to validate the design and assembly methods. Results will be shown indicating that flipped high-power MMICs provide lower thermal resistances than their unflipped counterparts, resulting in lower junction temperatures and improved reliability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The cortisol awakening response - normal values and confounds. (2000)

In several recent investigations it could be demonstrated that the free cortisol response to awakening can serve as an useful index of the adrenocortical activity. When measured with strict reference to the time of awakening the assessment of this endocrine response is able to uncover subtle changes in hypothalamus-pituitary-adrenal (HPA) axis activity, which are, for instance, related to persisting pain, burnout and chronic stress. Furthermore, it has been suggested that the HPA axis might serve as an indicator of allostatic load in subjects exposed to prolonged environmental noise. In the present paper four separate studies with a total of 509 adult subjects were combined in order to provide reliable information on normal values for the free cortisol response to awakening. Corresponding with earlier findings, a mean cortisol increase of about 50% within the first 30 minutes after awakening was observed. The intraindividual stability over time was shown to be remarkably high with correlations up to r=.63 (for the area under the response curve). Furthermore, the cortisol rise after awakening is rather consistent, with responder rates of about 75%. Gender significantly influenced early morning free cortisol levels. Although women showed a virtually identical cortisol increase after awakening compared to men, a significantly delayed decrease was observed. Confirming and extending previous findings, the present study strongly suggests that neither age, nor the use of oral contraceptives, habitual smoking, time of awakening, sleep duration or using / not using an alarm clock have a considerable impact on free cortisol levels after awakening. The cortisol awakening response can be assessed under a wide variety of clinical and field settings, since it is non-invasive, inexpensive and easy-to-employ. The present data provide normal values and information on potential confounds which should facilitate investigations into the endocrine consequences of prolonged exposure to environmental noise.

Acaricidal Effect of Essential Oils From Lippia graveolens (Lamiales: Verbenaceae), Rosmarinus officinalis (Lamiales: Lamiaceae), and Allium sativum (Liliales: Liliaceae) Against Rhipicephalus (Boophilus) microplus (Acari: Ixodidae) (2011)

Acaricidal effects of three essential oils extracted from Mexican oregano leaves (Lippia graveolens Kunth), rosemary leaves (Rosmarinus officinalis L.), and garlic bulbs (Allium sativum L.) on 10-d-old Rhipicephalus (Boophilus) microplus (Canestrini) tick larvae were evaluated by using the larval packet test bioassay. Serial dilutions of the three essential oils were tested from a starting concentration of 20 to 1.25%. Results showed that both Mexican oregano and garlic essential oils had very similar activity, producing high mortality (90-100%) in all tested concentrations on 10-d-old R. microplus tick larvae. Rosemary essential oil produced >85% larval mortality at the higher concentrations (10 and 20%), but the effect decreased noticeably to 40% at an oil concentration of 5%, and mortality was absent at 2.5 and 1.25% of the essential oil concentration. Chemical composition of the essential oils was elucidated by gas chromatography-mass spectrometry analyses. Mexican oregano essential oil included thymol (24.59%), carvacrol (24.54%), p-cymene (13.6%), and y-terpinene (7.43%) as its main compounds, whereas rosemary essential oil was rich in a-pinene (31.07%), verbenone (15.26%), and 1,8-cineol (14.2%), and garlic essential oil was rich in diallyl trisulfide (33.57%), diallyl disulfide (30.93%), and methyl allyl trisulfide (11.28%). These results suggest that Mexican oregano and garlic essential oils merit further investigation as components of alternative approaches for R. microplus tick control.
Spatial preferential attachment networks: Power laws and clustering coefficients (2015)

We define a class of growing networks in which new nodes are given a spatial position and are connected to existing nodes with a probability mechanism favoring short distances and high degrees. The competition of preferential attachment and spatial clustering gives this model a range of interesting properties. Empirical degree distributions converge to a limit law, which can be a power law with any exponent $\tau>2$. The average clustering coefficient of the networks converges to a positive limit. Finally, a phase transition occurs in the global clustering coefficients and empirical distribution of edge lengths when the power-law exponent crosses the critical value $\tau=3$. Our main tool in the proof of these results is a general weak law of large numbers in the spirit of Penrose and Yukich.
