An approach to the design of fully actuated body extenders for material handling (2010)

This paper deals with the mechanical and control design of an exoskeletric power extender for the whole human body. A critical issue in the design of such kid of devices is granting a sufficient level of transparency. The authors propose two design conditions based on tracking force threshold and equilibrium considerations that should be complied. This methodology has been applied to the specific design of a body extender for material handling that is currently being developed at the PERCRO (PERceptual RObotics) Lab of Scuola Superiore S. Anna of Pisa, Italy.

Evidence for a dimer reconstruction at a metal-silicon interface (1989)

We show that the stable structure of a ${\mathrm{CoSi}}_{2}$/Si(001) interface involves a 2\ifmmode\times\else\texttimes\fi{}1 periodic array of Si dimers with bond length 0.23\ifmmode\pm\else\textpm\fi{}0.02 nm. We use a novel combination of quantitative transmission-electron diffraction, transmission-electron-microscope (TEM) imaging, and high-resolution TEM to solve the structure and have imaged separate 2\ifmmode\times\else\texttimes\fi{}1 and 1\ifmmode\times\else\texttimes\fi{}2 domains, \ensuremath{\sim}100 nm in size, over many \ensuremath{\mu}${\mathrm{m}}^{2}$ of the interface.
On evaluation of adaptive topic tracking systems (2005)

Summative evaluation methods for supervised adaptive topic tracking systems convolve the effect of system decisions on present utility with the effect on future utility. This paper describes a new formative evaluation approach that focuses on future utility for use in the design stage of adaptive systems. Topic model quality is assessed at a predefined set of points using a fixed document set to enhance comparability. Experiments using a vector-space topic tracking system illustrate the utility of this approach to formative evaluation.
Biodegradation of Malachite Green by Extracellular Laccase Producing Bacillus thuringiensis RUN1 (2013)

A bacteria strain Bacillus thuringiensis RUN1identifiedby 16s RNA gene phylogenetic analysiswas used to decolorize malachite green, a triphenylmethane dye in a simulated wastewater. The ability of the organism to produce extracellular laccase and degrade the dye were also investigated. Results showed that the organism decolorized (84.67 ± 1.19 %) malachite green at 40 mgl-1 within 6 h; and the decolorization was associated to laccase production by the organism experimentally. Laccase activity increased as the decolorization process progressed, with the highest activity value of 0.1043 ± 0.02 U/min/ mg protein recorded after 24 h of incubation using ABTS as substrate. In addition, FTIR analysis showed that the strain actually degraded the dye. It was therefore concluded that this strain of Bacillus thuringiensis will be relevant in the biotreatment of industrial effluent containing malachite green and in the production of laccase, an industrially important enzyme.
Compensation of reflection from an RF absorbent material with the help of a lattice of double split rings (2016)

The frequency dependences of the coefficients of reflection from a lattice of double split rings excited by an RF magnetic field and from an RF-absorbent composite based on resistive films or fibers are analyzed. It is shown that partial reflections from the surface of the composite and the closely spaced lattice can compensate each other and, thus, the reflection from the composite can be significantly reduced. It is experimentally confirmed that the reflection can be decreased by more than 15 dB as compared to the reflection from the composite in the absence of the lattice.
An agent architecture for intelligent information assistance (2010)

Human users trying to plan and accomplish information-dependent goals in highly dynamic environments with prevalent uncertainty must consult various types of information sources in their decision-making processes while the information requirements change as they plan and re-plan. When the users must make time-critical decisions in informationintensive tasks they become cognitively overloaded not only by the planning activities but also by the information-gathering activities at various points in the planning process. We have developed the ANTicipatory Information and Planning Agent (ANTIPA) to manage information adaptively in order to mitigate user cognitive overload. To this end, the agent brings information to the user as a result of user requests but most crucially, it proactively predicts the user’s prospective information needs by recognizing the user’s plan; pre-fetches information that is likely to be used in the future; and offers the information when it is relevant to the current or future planning decisions. This paper describes a fully implemented agent of the ANTIPA architecture using a decision-theoretic user model, and reports preliminary user study results.
A speaker system with Bass back-loading of unusual parameter values (1960)

Work with corner horn speakers has led to a philosophy that there is a narrow range of optimum size limited by performance on the one hand and cohesion of bass and treble events on the other. In the design of a new speaker system of size smaller than these limits, the horn principle was abandoned for the bass section but continued to be used for the midrange-tweeter functions in the interest of lowest distortion. The bass section is of the enclosure type with a tubular back exhaust, corresponding in principle to the Bass Reflex but differing in the high inertance of the port. Adjusted empirically, the response of the new speaker resembles that of a three-way corner-horn reference system. The new speaker may be used against a wall, but as in all speakers affords best performance in a corner. It may be used for any of the two or three positions of a stereo array, including the bridged or derived center output.
Structural Features of Sm- and Gd-Doped Ceria Studied by Synchrotron X-ray Diffraction and μ-Raman Spectroscopy (2015)

A structural study of Sm- and Gd-doped ceria was performed with the aim to clarify some unexplained structural features. (Ce1-xREx)O2-x/2 samples (RE ≡ Sm, Gd; x = 0, 0.1, ..., 1) were prepared by coprecipitation of mixed oxalates and subsequent thermal treatment at 1473, 1173, or 1073 K in air; they were then analyzed at room temperature both by synchrotron X-ray diffraction and μ-Raman spectroscopy. Two structural models were adopted to fit the experimental data, namely, a fluoritic one, resembling the CeO2 structure at low RE content, and a hybrid one at higher RE content, intermediate between the CeO2 and the RE2O3 structures. Two main transitions were detected along the compositional range: (a) an RE-dependent transition at the boundary between the fluoritic and the hybrid regions, of a chemical nature; (b) an RE-independent transition within the hybrid region at ∼0.5, having a purely geometrical nature. The presence of two finely interlaced F- and C-based structures within the hybrid region was confirmed, and hints of their composition were obtained by μ-Raman spectroscopy. The obtained results indicate a possible explanation for the non-Vegard behavioral trend of the cell parameters.

Short-cavity, edge-emitting lasers with high-reflectance, dielectric mirrors (2000)

The fabrication and characterization of short-cavity, edge-emitting lasers operating at 861 nm is reported. These lasers were fabricated with high-reflectance, dielectric mirrors formed by plasma-enhanced, chemical-vapor deposition. Lasers with cavity lengths of 64 and 32 μm had continuous-wave, room-temperature threshold currents of 4.0 and 2.9 mA, respectively. To determine the reflectance of the deposited dielectric mirrors, a simple relationship was derived that used the change in the laser threshold current density resulting from mirror deposition.
Can Treatment of Social Isolation and Loneliness Reduce Healthcare Utility? An analysis of Social Prescribing (2021)

The paper focuses on the practice of social prescribing as it is currently implemented through the National Health Service (NHS) of the United Kingdom. Social Prescribing is an emerging healthcare intervention aimed at referring patients to community-based activities. NHS promotes social prescribing as a method of reducing healthcare utilization in chronically ill patients. Current evidence on social prescribing is subject to significant variation and has not supported NHS’s claims. The potential link between feeling of social isolation, loneliness and chronic illness was further investigated through data from the National Social Life, Health & Aging Project (NSHAP). Data was tested for correlations between respondents’ self-report of heart problems (chi-squared) and systolic blood pressure (Pearson’s correlation), in relation to survey measures on subjects’ level of social isolation and loneliness. To control for common comorbidities of cardiovascular disease, respondents were excluded if they reported current smoking status, diagnosis of diabetes, or waist measurements relating to obesity. Logistic and linear regression was then performed to identify predictive models for self-reported heart problems and systolic blood pressure respectively. The study provides limited evidence for to support the impact of social prescribing. This limitation is driven by the high degree of variation amongst reported outcomes. Future policy initiatives should focus on developing the body of literature and establishing clear expectations for patient prognosis.
Green synthesis and thermoluminescence study on LiAlSiO4:Ce3+ nanophosphors for dosimetry applications (2020)

In this paper the LiAlSiO4:Ce3+ nanophosphors for different concentration were prepared by low temperature solution combustion method using aloe vera gel as a fuel. The thermoluminescences (TL) was used to characterize the synthesized nanophosphors after gamma irradiation at various doses from a 60Co source. The LiAlSiO4:Ce3+ (1-11 mol %) nanophosphors were irradiated for a total dose 1kGy. Also 7 mol% is irradiated by the different dose such as 1, 3, 6 and 10 kGy which shows good sensitivity for the radiation. The LiAlSiO4:Ce3+ (5 mol%) irradiated with 5 kGy was characterized upto 160 οC at heating rate by 3 and 7 οC/s. The TL analysis using glow curve deconvolution technique was also done for determining different trapping parameters. The obtained results confirm that the synthesized nanophosphors are suitable for dosimetry application.
Milk and meat consumption patterns and the potential risk of zoonotic disease transmission among urban and peri-urban dairy farmers in Ethiopia (2022)

Creating awareness about the risk factors for zoonotic transmission of diseases through training and media campaigns, improving meat hygiene through better abattoir services, and inducing behavioural change around meat sourcing, raw meat and raw milk consumption, are all crucial to the successful prevention and control of the spread of zoonotic diseases, including bTB.
Retention of Configuration and E/Z Stereoselectivity in the Photolysis of cis‐ and trans‐Tetraalkyl‐4‐methylene‐1‐pyrazolines (1991)

The isomeric 4‐methylene‐1‐pyrazolines cis ‐ and trans ‐ 2 are synthesized by a Wittig reaction from the pyrazolin‐4‐ones cis ‐ and trans ‐ 1 , respectively. Direct irradiation with 350‐nm light of cis ‐ 2 affords the alkylidenecyclopropanes cis ‐ 8 , ( E )‐ and ( Z )‐ 9 (64: 17: 19) besides molecular nitrogen and small amounts of the 4‐methylenepyrazolidine cis ‐ 7 as a result of photoreduction. Under the same conditions, trans ‐ 2 is converted into trans ‐ 8 as well as ( E )‐ and ( Z )‐ 9 (64: 14: 22). The configurations of cis ‐ and trans ‐ 8 have been established by means of a 1,3‐dipolar cycloaddition with mesityl nitrile oxide which furnishes two cycloadducts from cis ‐ 8 , e.g. cis ‐ 14A and B , but only one cycloadduct from trans ‐ 8 , viz. trans ‐ 14 . The configurations of ( E )‐ and ( Z )‐ 9 have been assigned on the basis of homoallylic 1 H, 1 H coupling constants and nuclear Overhauser experiments. The results demonstrate that, on the least‐motion paths leading to cis ‐ and trans ‐ 8 , the configuration of the ring substituents in cis ‐ and trans ‐ 2 is completely retained. Of the non‐least‐motion products ( E )‐ and ( Z )‐ 9 the latter is favoured regardless of the configuration of the precursors cis ‐ and trans ‐ 2 though the extent of ( Z ) selectivity depends on that configuration. The results are interpreted in terms of bis‐orthogonal trimethylenemethane diradicals as primary intermediates from which irreversible paths bifurcate. Cyclization yields cis ‐ 8 (from cis ‐ 2 ) or trans ‐ 8 (from trans ‐ 2 ) and 90°‐bond rotations afford two diastereomeric mono‐orthogonal trimethylenemethane diradicals [( E )‐ and ( Z )‐ 18 ] which eventually cyclize to the corresponding non‐least‐motion products ( E )‐ 9 and ( Z )‐ 9 .
Simulation and sterilization of a surrogate soil organic matter for the study of the fate of trichloroethylene in soil (1997)

Abstract The objective of this paper is to present a procedure for the preparation and sterilization of a surrogate soil organic matter (SSOM) to study the chemical and biological interactions that may occur with trichloroethylene (TCE). For this purpose, the SSOM was prepared by composting sphagnum moss, a readily available and rather homogenous material. Both gamma irradiation and autoclaving were compared for their ability to effectively sterilize the SSOM. The efficiency of gamma irradiation, at varying intensities, was compared with that of autoclaving. Irradiation of SSOM at 50 kGy was found to be the most effective method of sterilization tested. Therefore, the effect of 50 kGy gamma irradiation on the surface properties of the SSOM (as evidenced by the cation exchange capacity (CEC), specific surface area (SSA), pH, infrared spectrophotometry (IRS), and TCE sorption isotherms) were compared with the non‐sterilized SSOM. Although there were differences in the CEC and SSA for the two materials, the IRS of sterilized and unsterilized SSOM were similar as was sorption of aqueous TCE at initial concentrations of 2 to 130 mg‐L‐1.
Identification of a high incidence region for retroviral vector integration near exon 1 of the LMO2locus (2009)

Therapeutic retroviral vector integration near the oncogene LMO2 is thought to be a cause of leukemia in X-SCID gene therapy trials. However, no published studies have evaluated the frequency of vector integrations near exon 1 of the LMO2 locus. We identified a high incidence region (HIR) of vector integration using PCR techniques in the upstream region close to the LMO2 transcription start site in the TPA-Mat T cell line. The integration frequency of the HIR was one per 4.46 x 10(4) cells. This HIR was also found in Jurkat T cells but was absent from HeLa cells. Furthermore, using human cord blood-derived CD34+ cells we identified a HIR in a similar region as the TPA-Mat T cell line. One of the X-linked severe combined immunodeficiency (X-SCID) patients that developed leukemia after gene therapy had a vector integration site in this HIR. Therefore, the descriptions of the location and the integration frequency of the HIR presented here may help us to better understand vector-induced leukemogenesis.

An Up-regulation of IRF-1 After a Spinal Cord Injury: Implications for Neuronal Apoptosis (2015)

IRF-1, a kind of transcription factor, is expressed in many cell types, except in early embryonal cells. IRF-1 has played an essential role in various physiological and pathological processes, including tumor immune surveillance, viral infection, development of immunity system and pro-inflammatory injury. However, the expression and function of IRF-1 in spinal cord injury (SCI) are still unknown. In this study, we have performed an acute SCI model in adult rats and investigated the dynamic changes of IRF-1 expression in the spinal cord. Western blot have shown that IRF-1 protein levels gradually increased, reaching a peak at day 3 and then gradually declined to a normal level at day 14 after SCI. Double immunofluorescence staining showed that IRF-1 immunoreactivity was found in neurons, but not in astrocytes and microglia. Additionally, colocalization of IRF-1/active caspase-3 was detected in neurons. In vitro, IRF-1 depletion, by short interfering RNA, obviously decreases neuronal apoptosis. In conclusion, this is the first description of IRF-1 expression in spinal cord injury. Our results suggested that IRF-1 might play crucial roles in CNS pathophysiology after SCI.
Synthesis of epoxy monomers that undergo synergistic photopolymerization by a radical‐induced cationic mechanism (2001)

Abstract A series of novel, cycloaliphatic, cationically photopolymerizable epoxide monomers bearing benzyl ether groups were prepared. These monomers display a considerable enhancement in the rate of their cationic ring‐opening polymerizations in comparison with monomers that do not contain such groups. In this article, a synergistic free‐radical mechanism is proposed that accounts for this effect, and supporting evidence is offered for its verification. During UV irradiation of an onium salt cationic photoinitiator, the aryl radicals that are generated abstract labile benzyl hydrogens present in such monomers to generate the corresponding carbon‐centered radicals. Subsequently, these radicals are oxidized to benzyl carbocations by the onium salt via a nonphotochemical chain process. The observed increase in the rate and extent of the cationic ring‐opening polymerization of the epoxide monomers is due to the aforementioned mechanism, which effectively increases the number of reactive cationic species present during polymerization. © 2001 John Wiley &amp; Sons, Inc.

Genomic Characterization of the Fruity Aroma Gene, FaFAD1, Reveals a Gene Dosage Effect on γ-Decalactone Production in Strawberry (Fragaria × ananassa) (2021)

Strawberries produce numerous volatile compounds that contribute to the unique flavors of fruits. Among the many volatiles, γ-decalactone (γ-D) has the greatest contribution to the characteristic fruity aroma in strawberry fruit. The presence or absence of γ-D is controlled by a single locus, <i>FaFAD1</i>. However, this locus has not yet been systematically characterized in the octoploid strawberry genome. It has also been reported that the volatile content greatly varies among the strawberry varieties possessing <i>FaFAD1</i>, suggesting that another genetic factor could be responsible for the different levels of γ-D in fruit. In this study, we explored the genomic structure of <i>FaFAD1</i> and determined the allele dosage of <i>FaFAD1</i> that regulates variations of γ-D production in cultivated octoploid strawberry. The genome-wide association studies confirmed the major locus <i>FaFAD1</i> that regulates the γ-D production in cultivated strawberry. With the hybrid capture-based next-generation sequencing analysis, a major presence-absence variation of <i>FaFAD1</i> was discovered among γ-D producers and non-producers. To explore the genomic structure of <i>FaFAD1</i> in the octoploid strawberry, three bacterial artificial chromosome (BAC) libraries were developed. A deletion of 8,262 bp was consistently found in the <i>FaFAD1</i> region of γ-D non-producing varieties. With the newly developed InDel-based codominant marker genotyping, along with γ-D metabolite profiling data, we revealed the impact of gene dosage effect for the production of γ-D in the octoploid strawberry varieties. Altogether, this study provides systematic information of the prominent role of <i>FaFAD1</i> presence and absence polymorphism in producing γ-D and proposes that both alleles of <i>FaFAD1</i> are required to produce the highest content of fruity aroma in strawberry fruit.
