Interface properties of an AlN/(AlN)<i><sub>x</sub></i> (SiC)<sub>1–<i>x</i></sub>/4H‐SiC heterostructure (2006)

Abstract The crystal structure and compositional changes near the two interfaces of a AlN/(AlN) x (SiC) 1– x /4H‐SiC heterostructure prepared by sublimation‐recondensation growth were examined by cross‐sectional transmission electron microscopy. Deposition of an (AlN) x (SiC) 1– x layer between a SiC seed and a bulk AlN crystal is potentially beneficial for gradually changing the lattice constants and coefficient of thermal expansion from SiC to AlN. A compositional transition layer adjacent to the 4H‐SiC substrate suggested interdiffusion between the substrate and the alloy layer. The alloy had the 4H‐polytype crystal structure in this layer; above the layer, the alloy exhibited the typical 2H‐polytype. Voids were present at the AlN/(AlN) x (SiC) 1– x interface, due to the decomposition of the (AlN) x (SiC) 1– x layer before the AlN layer had completely coalesced. The nominally pure AlN layer contained approximately 8% of Si and C, possibly coming from the decomposition of the alloy layer and/or the substrate during growth of the AlN layer. Both interfaces were abrupt, to less than 50 nm, with low densities of threading dislocations. Dislocations in both the (AlN) x (SiC) 1– x and AlN layers were not threading, but ran parallel to the (0001) planes. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Short-Limbed dwarfism and ocular defects in the Samoyed dog (1983)

A syndrome of short-limbed dwarfism and ocular defects was found in Samoyed dogs. The most prominent abnormalities were small stature and valgus deformity of the carpi. Radiographic evidence of retarded growth at the distal ulnar physis was apparent by 12 weeks of age. Ocular defects included cataracts and retinal detachment. Family studies and limited breeding experiments were consistent with an autosomal recessive mode of inheritance.
Nanoassemblies of sulfonated polyaniline multilayers (2000)

A self-assembly layer-by-layer (LBL) technique was used for the sequential adsorption of polycation, poly(diallyldimethylammonium chloride) (PDDA) and polyanion, sulfonated polyaniline (SPANI) on glass, indium-tin-oxide (ITO) coated glass plates, polystyrene sulfonate (PSS)/glass and PSS/ITO surfaces, respectively. The building up of such multilayers was characterized by the increment of the adsorbed amount through UV-visible spectroscopy and cyclic voltammetry. The atomic force microscopic study showed the granular surface topology of such self-assembled films of sulfonated polyaniline. PDDA/SPANI LBL films were electrically active and detailed electrochemical parameters were investigated.

LIVE FIRE LOAD IN LARGE SCALE BOOK STORES : ITS CHARACTERIZATION AND FACILITATION OF ITS SITE INVESTIGATION (2007)

Investigation of the properties of live fire load is conducted on large book stores from the interest on performance based fire safety design. The study focuses not only the report of fire load, surface area to mass ratio but also development of a simplified site investigation methodology of fire load of book stores where extreme difficulty is anticipated for the few yearly holidays available for such investigation. In this report, the characteristics of live fire load were grasped for fire safety design of large book stores and a methodology for the measurement of fire load was developed to reduce the effort of investigation. This proposed method was essentially developed from the distinction of the characteristics of live fire load like the arrangement and shape of book cases. The results reveal that the fire load is highly dependent on the height and material of bookcases. This paper also indicates that the prescribed total heat release for book store in building code standards of Japan, 960MJ/m^2, is not on the dangerous side estimation because the investigation has resulted in total heat release over twice larger, and the surface area per unit weight ratio is smaller than 1/4 the previous reports on other occupancies. These suggest that a fire in a large book store may proceed generally notably more slowly and last longer than in other building occupancies if not extinguished. The proposed simplified investigation method is found to reduce manpower necessary for the site investigation by 80% and enable site investigation in short time before or after the business hours.
Nanowire architectures for iodide free dye-sensitized solar cells (2013)

In this study, we show that the performance of iodide free redox couples in dye-sensitized solar cells could be significantly improved by engineering the electron transport and surface properties of the electrode materials. Specifically, tin oxide nanowires electrophoretically coated with titania nanoparticles and subsequently passivated with a submonolayer of alumina by atomic layer deposition show a remarkable ten-fold increase in short-circuit current densities over those obtained with titania nanoparticles, even when a typical N-719 dye is used for sensitization. Comparison of the performance of different electrode materials such as nanowires, nanoparticles and nanowire–nanoparticle hybrid architectures of tin oxide and titania suggests that fast electron transport helps in improving the short-circuit current density with ferrocene/ferrocenium and TEMPO redox couples. The nature of the surface trap states and their passivation have a significant effect on the electron lifetimes in the semiconductor and the resulting open-circuit voltage with these redox couples. The higher electron diffusion lengths with the tin oxide nanowire based architectures allow for thicker electrodes with enhanced dye loading. The analysis of literature data on DSCs made using different dyes and alternate redox couples suggests smaller delta G or reorganization energy for non-ruthenium based dyes.
Enclosure Methods for Multivariate Differentiable Functions and Application to Global Optimization (2020)

The efficiency of global optimization methods in connection with interval arithmetic is no more to be demonstrated. They allow to determine the global optimum and the corresponding optimizers, with certainty and arbitrary accuracy. One of the main features of these algorithms is to deliver a function enclosure defined on a box (right parallelepiped). The studied method provides a lower bound (or upper bound) of a function in that box throughout two different strategies. As we shall see, these algorithms associated with various Branch and Bound methods lead to accelerated convergence and permit to avoid the cluster problem.
Productive herpes simplex virus in brain of elderly normal subjects and Alzheimer's disease patients (2004)

It was previously shown that herpes simplex virus type 1 (HSV1) DNA resides latently in a high proportion of aged brains and that in carriers of the type 4 allele of the apolipoprotein E gene (APOE-epsilon4), it confers a strong risk of Alzheimer's disease. It was suggested that initial entry of brain by HSV1 and any subsequent reactivation(s) would cause a type of limited encephalitis, the resulting damage being more harmful in APOE-epsilon4 carriers. Reactivation(s) would induce synthesis of intrathecal antibodies; these are long-lived after herpes simplex encephalitis so they were sought in cerebrospinal fluid (CSF) of Alzheimer's disease patients and age-matched normal subjects. Intrathecal antibodies to human herpesvirus 6 (HHV6) were also sought as DNA of this virus has been detected previously in a high proportion of Alzheimer's disease brains. Antibody indices for HSV and HHV6 were measured using indirect ELISA for IgG antibody, and single radial immunodiffusion was used for albumin, in serum and CSF. A raised antibody index (>1.5) indicative of virus-specific intrathecal HSV1 IgG synthesis was found in 14/27 (52%) Alzheimer's disease patients and 9/13 (69%) age-matched normals (difference non-significant). A raised antibody index to HHV6 was detected in 22% of the Alzheimer's disease patients and in no normals, so presumably this virus either did not reactivate in brain or it elicited only short-lived intrathecal antibodies. The HSV1 results confirm the original PCR findings that show the presence of HSV1 DNA sequences in many elderly brains, and indicate also that the whole functional HSV1 genome is present, and that the virus has replicated.
Spin injection into carbon nanotubes and a possible application in spin-resolved scanning tunnelling microscopy (2001)

We present magnetotransport measurements on multiwall nanotubes contacted by ferromagnetic electrodes that are 1 µm apart. The observed magnetoresistance of 2.2% is consistent with a spin-scattering length of at least 380 nm. We further discuss a novel concept for spin-resolved scanning tunnelling microscopy (SR-STM) with a carbon-nanotube tip. The concept relies on a long spin-scattering length as well as on spin-dependent scattering at the interfaces to the ferromagnetic electrodes. The observed magnitude of the magnetoresistance effect and the distance between the electrodes are large enough for application in a SR-STM.
Mutations in the Gene Encoding for the <i>β</i> 2-adrenergic Receptor in Normal and Asthmatic Subjects (1993)

It has long been hypothesized that a defective beta 2-adrenergic receptor (beta 2AR) may be a pathogenic factor in bronchial asthma. We examined the gene encoding the beta 2AR to assess the frequency of polymorphisms in 51 patients with moderate to severe asthma and 56 normal subjects. Nine different point mutations were found in both heterozygous and homozygous forms at nucleic acid residues 46, 79, 100, 252, 491, 523, 1053, 1098, and 1239. No mutations resulting in large deletions or frame shifts were detected. Of these nine polymorphisms, four were found to cause changes in the encoded amino acids at residues 16, 27, 34, and 164. The most frequent polymorphisms were arginine 16 to glycine (Arg16-->Gly) and glutamine 27 to glutamic acid (Gln27-->Glu). The other two polymorphisms, valine 34 to methionine, and threonine 164 to isoleucine, occurred in only four subjects. The incidence of beta 2AR homozygous polymorphisms was no greater in asthmatic patients as compared with controls (Arg16-->Gly: 53% versus 59%, Gln27-->Glu: 24% versus 29%, respectively; P = NS). Some subjects were found to have both of these polymorphisms simultaneously, but there was no difference in incidence between the two groups, with 23% of asthmatics and 28% of normal subjects being homozygous for both polymorphisms. The apparently normal subjects with both polymorphisms did not have subclinical hyperreactive airways disease as determined by methacholine challenge testing. In the asthma group, one mutation (Arg16-->Gly) identified a subset of patients with a distinct clinical profile.(ABSTRACT TRUNCATED AT 250 WORDS)

Mining User Interests from Personal Photos (2015)

Personal photos are enjoying explosive growth with the popularity of photo-taking devices and social media. The vast amount of online photos largely exhibit users' interests, emotion and opinions. Mining user interests from personal photos can boost a number of utilities, such as advertising, interest based community detection and photo recommendation. In this paper, we study the problem of user interests mining from personal photos. We propose a User Image Latent Space Model to jointly model user interests and image contents. User interests are modeled as latent factors and each user is assumed to have a distribution over them. By inferring the latent factors and users' distributions, we can discover what the users are interested in. We model image contents with a four-level hierarchical structure where the layers correspond to themes, semantic regions, visual words and pixels respectively. Users' latent interests are embedded in the theme layer. Given image contents, users' interests can be discovered by doing posterior inference. We use variational inference to approximate the posteriors of latent variables and learn model parameters. Experiments on 180K Flickr photos demonstrate the effectiveness of our model.
Prevention of acute mountain sickness by low positive end-expiratory pressure in field conditions (2004)

This field study shows that PEEP could be an efficient method with which to prevent acute mountain sickness without adverse effects. However, the ergonomics of the PEEP system must be improved to make its use more practical in the future.
TTG-2, a new gene encoding a cysteine-rich protein with the LIM motif, is overexpressed in acute T-cell leukaemia with the t(11;14)(p13;q11). (1991)

We have cloned 70 kb of DNA from chromosome 11p13 at the site of a recurrent translocation in T-cell leukaemia (T-ALL): t(11;14)(p13;q11). The translocation involves the TCR-delta gene on 14q11 and a new site on 11p13. Two new and 10 previously identified translocations all mapped within 25 kb on 11p13, the 11p13 T-cell translocation cluster (11p13 ttc). A search for expressed sequences surrounding the breakpoint cluster region on 11p13 identified a gene telomeric of all breakpoints which is overexpressed in three T-ALL samples with a t(11;14). The gene T-cell translocation gene (TTG-2) encodes a small cysteine-rich protein. Forty-eight per cent of the amino acids are identical with another translocation-deregulated gene, TTG-1 (T-cell translocation gene 1 or rhombotin) in 11p15. There are two copies of a cysteine-rich motif in both proteins. Two tandem copies of the same cysteine-rich motif are also present in the recently described lin-11, isl-1 and mec-3 gene products, and one motif is found in the CRIP protein. Therefore the proteins encoded by these two translocation-deregulated genes belong to this new class of cysteine-rich proteins with the 'LIM' motif, which are important in normal development.
Crop Allelopathy and Its Role in Ecological Agriculture (2001)

Summary A number of crops exhibit allelopathic interactions that play a significant role in the complex environment of agroecosystems. Several studies have shown that allelopathic crops reduce growth, development and yield of other crops growing simultaneously or subsequently in the fields. Another aspect of interest regarding crop allelopathy is that allelochemicals may exhibit inhibitory effect on the same crop which is commonly called as crop autotoxicity. It is predominantly common in fields where sole cropping under reduced or no-tillage system is practiced. Though any crop part can be allelopathic, including even the pollens, but decomposing crop residues exhibit more influence on other plants. Furthermore, the extent of allelopathy by a crop plant varies with age, part and type of cultivar being used. Nowadays allelo-pathic crops are being used as an important tool in managing weeds and harmful pests under sustainable pest management programs. In this context several cover/smother and green manure crops with allelopathic nature hold a good promise as well as challenge for the future as they have a potential to suppress noxious weeds. Likewise, the decomposing residues of such crops can also be used for managing harmful weeds and pests vis-à-vis maintaining the sustainability of the system. The traditional practice of crop rotation which declined with the discovery of synthetic herbicides can also be revived, if allelopathic potential of rotational crops is well understood. Selection of cultivars with high allelopathic potential/high competitiveness is another possible way by which crop allelopathy can be better utilized for weed control and yield enhancement. Crops with less allelopathic potential can be genetically improved by incorporating desired genes encoding the synthesis of allelochemicals. Pure allelochemicals extracted and identified from some crop plants can also be used as bioherbicides.
Fabrication of Visible-Light-Transparent Solar Cells Using p-Type NiO Films by Low Oxygen Fraction Reactive RF Sputtering Deposition (2013)

Visible-light-transparent p-type NiO films were deposited by reactive RF sputtering under unintentional heating. An optical transmittance of >80% was obtained in the wavelength range of 500–800 nm when the films were deposited under a very low O 2 fraction in the gas phase O 2 /(Ar+ O 2 ) = 0.5%. This result may reflect a decrease in the concentration of Ni vacancies due to the increase in their formation energy under oxygen-poor deposition conditions. Heterostructure pn junctions consisting of p-type NiO and n-type ZnO layers were also deposited. We eventually observed a slight but noticeable photovoltaic effect.
Compact and miniature snapshot imaging polarimeter (2008)

We present and demonstrate a compact and miniature snapshot imaging polarimeter camera; it is anticipated that such a camera can be scaled down to less than 1.5 cm. Two Savart plates are used at the pupil plane to generate multiple fringes to encode the full Stokes vector in a single image. A geometric ray model is developed to explain the system. The numerical simulation based on this model is presented. Finally, the validity of the device is demonstrated by showing experimental results.
The Endoparasitic Nematophagous Fungus Meria coniospora Infects Nematodes Specifically at the Chemosensory Organs (1983)

Conidia of the endoparasitic fungus Meria coniospora infected the bacterial-feeding nematode Panagrellus redivivus at specific sites, namely the mouth region and in male nematodes also in the tail. Plant-parasitic nematodes were also infected in other parts of the body. The specific infection sites in P. redivivus were the sensory organs, which are the sites of chemoreception. Blocking of chemoreceptors by adhered conidia of M. coniospora caused a complete loss of the ability of nematodes to be attracted to different sources of attractants. Inhibition of conidial adhesion by means of sugar haptens suggested a lectin-carbohydrate interaction. Out of 21 sugars only N-acetylneuraminic acid inhibited the adhesion, indicating the importance of sialic acids in the infection process. Reduction of conidial adhesion by treatment of nematodes with neuraminidase further supported this view.
Characterization of a histone-like protein extracted from yeast mitochondria. (1979)

Analysis of proteins isolated by affinity chromatography on DNA-cellulose from highly purified yeast mitochondria shows that these organelles do not contain histones but have in abundance a DNA-binding protein of 20,000 daltons. The purification yield of this protein, called HM, indicates that mitochondria have at least an equal mass of HM relative to DNA. The amino acid composition and its electrophoretic characterization reveal that HM, rich in lysine, is slightly basic and heat stable. HM appears to be coded by the yeast nucleus, as shown by its presence in several "petite" mutants. We have shown that HM, like histones or histone-like proteins, is able to introduce superhelical turns into circular relaxed DNA in the presence of a nicking-closing activity.
Technology mapping and architecture evalution for <i>k/m</i> -macrocell-based FPGAs (2005)

In this article, we study the technology mapping problem for a novel field-programmable gate array (FPGA) architecture that is based on k -input single-output programmable logic array- (PLA-) like cells, or, k/m -macrocells. Each cell in this architecture can implement a single output function of up to k inputs and up to m product terms. We develop a very efficient technology mapping algorithm, k_m_flow, for this new type of architecture. The experimental results show that our algorithm can achieve depth-optimality on almost all the testcases in a set of 16 Microelectronics Center of North Carolina (MCNC) benchmarks. Furthermore it is shown that on this set of benchmarks, with only a relatively small number of product terms ( m ≤ k + 3), the k/m -macrocell-based FPGAs can achieve the same or similar mapping depth compared with the traditional k -input single-output lookup table- ( k -LUT-) based FPGAs. We also investigate the total area and delay of k/m -macrocell-based FPGAs and compare them with those of the commonly used 4-LUT-based FPGAs. The experimental results show that k/m -macrocell-based FPGAs can outperform 4-LUT-based FPGAs in terms of both delay and area after placement and routing by VPR on this set of benchmarks.
Synthesis of Reactive Polymeric Dyes as Textile Auxiliaries (2003)

Abstract New polymeric materials containing amino‐substituted azobenzene chromophores and reactive functional groups and characterized by some hydrophilicity were prepared with the aim of investigating alternative textile dyeing routes. The indicated materials were obtained either by copolymerization of suitable monomers or by modification of preformed polymers. In both cases commercial 4‐amino‐2′,3‐dimethylazobenzene (FG) was used as chromogenic compound. According to the first synthetic strategy, the methacrylamido derivative of FG was copolymerized by free radical initiation with different monomers, such as methyl methacrylate, glycidyl methacrylate, N ‐ tert ‐butylacrylamide, methacrylic acid, N ‐vinyl‐2‐pyrrolidinone, and vinyl acetate. Reaction of FG with preformed polymers containing epoxy groups generally afforded crosslinked materials. On the other hand, low FG loading extents were recorded by amidation of polymers containing carboxylic groups. Indeed, almost quantitative conversions were obtained only in the reaction of FG with anhydride containing polymers. The chemical structure, molecular weight properties, and the physical‐chemical characteristics of all synthesized polymeric dyes were thoroughly investigated. Some very preliminary dyeing tests of different cloth types with the prepared polymeric dyes were also performed.

Preferential heterodimerization of a bispecific diabody based on a humanized anti-EGFR antibody 528 (2008)

We report the utility of in vitro refolding in the preparation of monomorphous hEx3 bispecific diabodies with epidermal growth factor receptor and CD3 retargeting from insoluble aggregates in Escherichia coli. Appropriate interaction between cognate variable heavy and light chains led to the formation of functional hEx3 heterodimers in a diabody format rather than inactive homodimers. The refolded hEx3 was found to exhibit almost the equivalent activity to the hEx3 and single-chain hEx3 (hEx3-scDb) prepared in a mammalian secretion system. We suggest that the preparation of hEx3 from bacterial insoluble material by means of in vitro refolding would be useful for industrial-scale production of the diabody for its potential use in clinical studies.
