3D printed intraocular lens for managing the color blindness (2023)

• Atto 565 dye-tinted intraocular lenses were fabricated using a vat-photopolymerization 3D printing technique. • Almost 50% blockage of the unwanted wavelength (565 nm) which is responsible for red-green colorblindness. • The focal length was found to be ∼ 35 mm which is close to design of the IOL utilised for the 3D printing. • Atto dye doesn't influence the optical performance of IOLs except blockage of the unwanted wavelength. Color vision deficiency (CVD) or color blindness is one of the ocular disorders dominated in the male population, where the CVD individual faces difficulty in distinguishing the shades of certain colors, and so far, no proper cure is available. Although efforts have been made to improve color recognition with the help of some wearables such as glasses and contact lenses (tinted with dyes to enable wavelength filtering capability), but permanent implants to correct CVD are yet to be explored. Towards providing a permanent solution to CVD patients, an effort has been made to develop 3D printed intraocular lenses (IOLs), using a vat-photopolymerization technique, tinted with Atto 565 dye (wavelength-specific filtering dye), which can be implanted in human eyes. A transparent resin was produced from the combination of poly-2-hydroxyethyl methacrylate (pHEMA), polyethylene glycol diacrylate (PEGDA), and trimethylbenzoyl diphenylphosphine oxide (TPO). While benefiting from the advantages established from the customization of the resin and the 3D printing process, IOLs were 3D printed with and without the tinting dye. The 3D printed IOLs were characterized by optical properties. The dye-tinted IOL was able to successfully block up to 50% of the unwanted wavelength (i.e., 565 nm) and exhibited high transparency for the remaining wavelengths in the visible light spectrum. The lenses also exhibited strong optical focusing property and polarization independent transmission. 3D printed intraocular lenses may be printed as per the patient's needs and requirements; with customised focal lengths and tints to contest the correct CVD type and other eye conditions.

Molecular characterization of infectious bursal disease virus isolates from Nepal based on hypervariable region of VP2 gene. (2005)

Two Infectious bursal disease virus (IBDV) isolates, NP1SSH and NP2K were obtained from a severe infectious bursal disease (IBD) outbreak in Nepal in 2002. The hypervariable (HV) region of VP2 gene (1326 bp) of the isolates was generated by RT-PCR and sequenced. The obtained nucleotide sequences were compared with those of twenty other IBDV isolates/strains. Phylogenetic analysis based on this comparison revealed that NP1SSH and NP2K clustered with very virulent (vv) IBDV strains of serotype 1. In contrast, classical, Australian classical and attenuated strains of serotype 1 and avirulent IBDV strains of serotype 2 formed a different cluster. The deduced amino acid sequences of the two isolates showed a 98.3% identity with each other and 97.1% and 98.3% identities, respectively with very virulent IBDV (vvIBDV) isolates/strains. Three amino acids substitutions at positions 300 (E-->A), 308 (I-->F) and 334 (A-->P) within the HV region were common for both the isolates. The amino acids substitutions at positions 27 (S-->T), 28 (I-->T), 31 (D-->A), 36 (H-->Y), 135 (E-->G), 223 (G-->S), 225 (V-->I), 351 (L-->I), 352 (V-->E) and 399 (I-->S) for NP1SSH and at position 438 (I-->S) for NP2K were unique and differed from other IBDV isolates/strains. NP1SSH and NP2K showed highest similarity (97.8%) with the BD399 strain from Bangladesh as compared with other vvIBDV isolates/strains. We conclude that the NP1SSH and NP2K isolates of IBDV from Nepal represent vvIBDV of serotype 1.

High Open-Circuit Voltage: Fabrication of Formamidinium Lead Bromide Perovskite Solar Cells Using Fluorene–Dithiophene Derivatives as Hole-Transporting Materials (2016)

Four different fluorene–dithiophene derivative-based hole-transporting materials (HTMs) (SO7–10) have been synthesized via a facile route and were successfully used in the fabrication of formamidinium lead bromide perovskite solar cells. Detailed characterization of the new compounds was carried out through 1H/13C NMR spectroscopy, mass spectrometry, ultraviolet–visible and photoluminescence spectroscopy, and cyclic voltammetry. Under AM1.5 G illumination, the mesoscopic CH(NH2)2PbBr3 perovskite solar cell employing SO7 as the HTM displayed an outstanding photovoltage (Voc) of 1.5 V with an efficiency (η) of 7.1%. The photovoltaic performance is on par with the device using the state-of-the-art Spiro-OMeTAD as HTM, which delivered a Voc of 1.47 V and a maximum η of 6.9%. A density functional theory approach with GW simulations including spin–orbit coupling and electrochemical measurements revealed deeper highest occupied molecular orbital levels for newly synthesized fluorene–dithiophene derivatives, which eventually makes them promising HTMs for perovskite solar cells, especially when high photovoltage is desired.
Evidence that rotons in helium II are interstitial atoms (2017)

Superfluid helium II contains excitations known as rotons. Their properties have been studied experimentally for more than 70 years but their structure is not fully understood. Feynman's 1954 description, involving rotating flow patterns, does not fully explain later experimental data. Here we identify volumetric, thermodynamic, colloidal, excitation, x-ray and neutron scattering evidence that rotons are composed of interstitial helium atoms. We show in particular that they have the same mass, effective mass and activation energy within experimental accuracy. They readily move through the substrate, and couple through lattice vibrations to produce quantized, loss-free flow which corresponds to the observed superflow. Our observations revive London's 1936 conclusion that helium II has a relatively open crystal-like lattice with enough free volume for atoms to move relative to one another, and reconcile it with London's 1938 description of a quantum fluid.
Current and emerging treatments for the management of osteogenesis imperfecta (2010)

Osteogenesis imperfecta (OI) is the most common bone genetic disorder and it is characterized by bone brittleness and various degrees of growth disorder. Clinical severity varies widely; nowadays eight types are distinguished and two new forms have been recently described although not yet classified. The approach to such a variable and heterogeneous disease should be global and therefore multidisciplinary. For simplicity, the objectives of treatment can be reduced to three typical situations: the lethal perinatal form (type II), in which the problem is survival at birth; the severe and moderate forms (types III-IX), in which the objective is 'autonomy'; and the mild form (type I), in which the aim is to reach 'normal life'. Three types of treatment are available: non-surgical management (physical therapy, rehabilitation, bracing and splinting), surgical management (intramedullary rod positioning, spinal and basilar impression surgery) and medical-pharmacological management (drugs to increase the strength of bone and decrease the number of fractures as bisphosphonates or growth hormone, depending on the type of OI). Suggestions and guidelines for a therapeutic approach are indicated and updated with the most recent findings in OI diagnosis and treatment.
Progressive atypia in spontaneous and N-nitrosodiethylamine- induced hepatocellular adenomas of C3H/HeNCr mice (1992)

The progression of hepatocellular adenomas to carcinomas has been less well documented in mice than in rats. We studied progression of spontaneous and chemically induced hepatocellular adenomas in male C3H/HeNCr mice by image analysis. Spontaneous lesions in 15, 18 and 21 month old untreated male C3H/HeNCr mice and experimentally induced lesions were examined. Experimental group 1 received a single i.p. injection of N-nitrosodiethylamine (DEN) (5 mg/kg body wt) at 15 days of age. Groups 2 and 3 were injected a second time with DEN at 15 or 20 weeks of age (75 mg/kg body wt), with interim sacrifices at 11, 16 and 34 weeks after the second DEN injection. Atypia in adenomas were classified into four grades according to cell size, tinctorial changes, cellular pleomorphism and trabecular pattern. At earlier stages of the neoplastic process (11 or 16 weeks after the second DEN dose), most adenomas were well-differentiated lesions with no atypia or focal grade 1 or 2 atypia. At later stages (34 weeks after the second DEN dose), a large proportion of hepatocellular tumors were classified as adenoma with grade 3 atypia or carcinoma. The proportion of carcinomas in mice treated with a second dose of DEN at 20 weeks of age was significantly higher than in mice treated with a single dose of DEN or in mice given a second dose of DEN at 15 weeks. A positive correlation was found between increase in the size of lesions and increased atypia in both spontaneous and DEN-induced lesions and with age for spontaneous tumors. These results support the hypothesis that mouse hepatocellular adenomas are truly neoplastic lesions in different stages of progression toward malignancy.
Immobilization of DNA onto a polymer support and its potentiality as immunoadsorbent (2000)

Immobilization of DNA to the surface of poly(ethylene terephthalate) (PET) microfibers with a high specific surface area of 0.83 m(2)/g was carried out to give the fiber surface an affinity for anti-DNA antibody. Following ozone oxidation, the microfibers were subjected to graft polymerization of monomers including acrylic acid, methacryloyloxyethyl phosphate, N,N-dimethylaminoethyl methacrylate, N-vinylformamide, and glycidyl methacrylate. Calf thymus DNA was immobilized to the grafted fiber surface through either covalent binding or polyion complexation with the grafted polymer chains. The highest surface density of DNA immobilized (0.6 microg/cm(2)) was obtained when DNA was immobilized through formation of phosphodiester linkage between the hydroxyl group of DNA and the phosphate group in grafted poly(methacryloyloxyethyl phosphate) using 1,1-carbonyldiimidazole, or through polyion complexation between the anionic DNA and the cationic grafted poly(N,N-dimethylaminoethyl methacrylate) chains. Batch adsorption of anti-DNA antibody to the grafted PET fibers with and without DNA immobilized on their surface was conducted with serum obtained from systemic lupus erythematosus model mice. The DNA-immobilized PET fibers exhibited a higher adsorption capacity and specificity than the others. In addition, the DNA-immobilized fibers effectively adsorbed human anti-DNA antibody.
Luminol–hydrogen peroxide–horseradish peroxidase chemiluminescence intensification by kosmotrope ammonium sulfate (2022)

The kosmotropic effect induced by ammonium sulfate (AS) at concentrations greater than approximately 2.8 M allows the marked intensification of chemiluminescence (CL) arising from a conventional luminol-hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>)-horseradish peroxidase (HRP) reaction. Because of the kosmotropic effect, CL is intensified by at least three orders of magnitude than that from the conventional HRP-catalyzed luminol reaction with no AS; the linear relationship between the CL intensity and the HRP concentration is established over the range of 0.3 pM to several tens of pM. The novel CL intensification effect on the HRP-catalyzed luminol CL can be stably and reproducibly induced.
A NEW TREE-STRUCTURE-SPECIFIED MULTISIGNATURE SCHEME FOR A DOCUMENT CIRCULATION SYSTEM (2011)

In this paper, the authors propose a new multisignature scheme with pairing-based cryptography, which can describe the tree structure of signers. In order to denote the relationship among a parent and its child signers, a dedicated middle key is generated on our scheme. In addition, we prove that our scheme is provably secure under the Gap-Diffie-Hellman assumption. Based on our proposal, we also implement the prototype of a document circulation system. In this system, a document is signed by members, who are divided into multiply layered groups. The browsing history can be confirmed by verifying the final signature on the document. The computational performance of the system is evaluated, and the result shows a good performance.

Whispering Gallery Mode Thermometry (2016)

This paper presents a state-of-the-art whispering gallery mode (WGM) thermometer system, which could replace platinum resistance thermometers currently used in many industrial applications, thus overcoming some of their well-known limitations and their potential for providing lower measurement uncertainty. The temperature-sensing element is a sapphire-crystal-based whispering gallery mode resonator with the main resonant modes between 10 GHz and 20 GHz. In particular, it was found that the WGM around 13.6 GHz maximizes measurement performance, affording sub-millikelvin resolution and temperature stability of better than 1 mK at 0 °C. The thermometer system was made portable and low-cost by developing an ad hoc interrogation system (hardware and software) able to achieve an accuracy in the order of a few parts in 10⁸ in the determination of resonance frequencies. Herein we report the experimental assessment of the measurement stability, repeatability and resolution, and the calibration of the thermometer in the temperature range from -74 °C to 85 °C. The combined standard uncertainty for a single temperature calibration point is found to be within 5 mK (i.e., comparable with state-of-the-art for industrial thermometry), and is mainly due to the employed calibration setup. The uncertainty contribution of the WGM thermometer alone is within a millikelvin.
Improving search quality in peer-to-peer file-sharing systems (2008)

Peer-to-peer (P2P) file-sharing is one of the most significant P2P applications nowadays in terms of number of participants and volume of data transferred. The large volume and diversity of data as well as the limited search functionalities and poor file description in a P2P file-sharing system make exhaustive searches for desired content infeasible. Therefore, better ways of retrieving and ranking query results are needed. 
This work introduces traditional information retrieval ranking into P2P file-sharing systems and metadata distribution techniques that are effective in finding data in query result sets, especially rare files in such a decentralized environment. Regarding the issue of poor data description, we consider the design of a fully distributed, automatic subsystem to gather other's descriptive metadata through probe queries. Experimental results indicate that the proposed techniques are effective in improving search quality with reasonable cost in both ranking and retrieving search results. 
To guarantee clients find and download desired genuine files, we also work on P2P spam characterization and detection, so as to further improve the search effectiveness in P2P file-sharing systems. We propose probing technique to collect more complete feature information of query results from the network and apply feature-based ranking for automatically detecting spam in P2P query result sets. Experimental results show that the proposed techniques dramatically improve the effectiveness of P2P spam detection with reasonable cost.
NEW WEIGHTED MULTILINEAR OPERATORS AND COMMUTATORS OF HARDY-CESARO TYPE (2015)

This paper deals with a general class of weighted multilinear Hardy-Cesaro operators that acts on the product of Lebesgue spaces and central Morrey spaces.Their sharp bounds are also obtained.In addition,we obtain sufficient and necessary conditions on weight functions so that the commutators of these weighted multilinear Hardy-Cesaro operators(with symbols in central BMO spaces) are bounded on the product of central Morrey spaces.These results extends known results on multilinear Hardy operators.

Matching-pursuit video coding .II. Operational models for rate and distortion (2002)

For pt. I see ibid., vol.12 , no.1, (2000).We introduce two models for predicting the rate and distortion of the matching-pursuit video codec. The first model is based on a pre-coding analysis pass using the full matching-pursuit dictionary. The second model is based on a reduced-complexity analysis pass. We evaluate these models for use within existing rate-distortion optimization techniques. Our prediction results suggest that the models have sufficient accuracy to be useful in this context, and that significant complexity reductions could be achieved compared to exact rate-distortion computation.
Fonetische articulatiestoornissen (2014)

Sprekers van een taal maken gebruik van een set van klanken om te kunnen communiceren. Het Nederlands kent ongeveer 35 verschillende klanken. Bij de verwerving van de moedertaalleert een kind elk van die klanken in de loop der tijd correct produceren. Bovendien leert het deze klanken ook combineren tot betekenisvolle syllaben en woorden. Sommige kinderen blijken echter problemen te ondervinden bij het correct leren produceren en/of gebruiken van de moedertaalklanken. Dergelijke problemen bij de verwerving van spraakklanken noemt men heel algemeen articulatiestoornissen.
Chemical constituents from Penianthus camerounensis Dekker (Menispermaceae) (2019)

Abstract The phytochemical study of the roots, leaves and twigs of Penianthus camerounensis Dekker (Menispermaceae) has led to the isolation and the characterization of 20 compounds. A ceramide, camerounamide ( 1 ), and a furoclerodanediterpenoid, camerounin ( 2 ), have not been described previously, while the compounds xylopic acid ( 3 ), syringaresinol ( 4 ), iso -propylmethylcyclohexa-1,4-diol ( 5 ), 1-(28-hydroxyoctacosanoyl)glycerol ( 6 ), scoparone ( 7 ), friedelin ( 8 ), friedelanol ( 9 ) and betulinic acid ( 10 ) are being reported for the first time from the genus Penianthus alongside 10 known compounds ( 11–20 ). Chemical structures were determined using 1D- and 2D-NMR spectroscopy, MS and chemical analysis. Their chemotaxonomic importance is discussed.
Yeast mutant affected for viability upon nutrient starvation: Characterization and cloning of the RVS161 gene (1991)

In yeast, nutrient starvation leads to entry into stationary phase. Mutants that do not respond properly to starvation conditions have been isolated in Saccharomyces cerevisiae. Among them the rvs161 mutant (RVS for Reduced Viability upon Starvation) is sensitive to carbon, nitrogen and sulphur starvation. When these nutrients are depleted in the medium, mutant cells show cellular viability loss with morphological changes. The mutation rvs161-1 is very pleiotropic, and besides the defects in stationary phase entry, the mutant strain presents other alterations: sensitivity to high salt concentrations, hypersensitivity to amino acid analogs, no growth on lactate or acetate medium. The addition of salts or amino acid analogs leads to the same morphological defects observed in starved cells, suggesting that the gene could be implicated mainly in the control of cellular viability. The gene RVS161 was cloned; it codes for a 30,252 daltons protein. No homology was detected with the proteins contained in the databases. Moreover, Southern analysis revealed the presence of other sequences homologous to the RVS161 gene in the yeast genome.
Gate-level netlist reverse engineering for hardware security: Control logic register identification (2016)

The heavy reliance on third-party resources, including third-party IP cores and fabrication foundries, has triggered the security concerns that design backdoors and/or hardware Trojans may be inserted into fabricated chips. While existing reverse engineering tools can help recover netlist from fabricated chips, there is a lack of efficient tools to further analyze the netlist for malicious logic detection and full functionality recovery. While it is relatively easy to identify the functional modules from the netlist using pattern matching methods, the main obstacle is to isolate control logic registers and reverseengineering the control logic. Upon this request, we proposed a topology-based computational method for register categorization. Through this proposed algorithm, we can differentiate data registers from control logic registers such that the control logic can be separated from the datapath. Experimental results showed that the suggested method was capable of identifying control logic registers in circuits with various complexities ranging from the RS232 core to the 8051 microprocessor.
Classification based character segmentation guided by Fast-Hessian-Affine regions (2011)

This paper presents a method of fast and accurate character localization for OCR (Optical Character Reader). We already proposed an acceleration framework of arbitrary classifiers, classifier molding, for real-time verification of characters printed by Industrial Ink Jet Printer (IIJP). In this framework, the behavior of accurate but slow character classifier is learnt by linear regression tree. The resulted classifier is up to 1,500 times faster than the original one but is not fast enough for real-time pyramidal scan of VGA images, which is necessary for scale-free character recognition. For solving this problem, we also proposed CCS (Classification based Character Segmentation). This method finds character arrangement that maximizes the sum of the likelihood of character regions assuming that all characters are horizontally aligned with almost regular intervals. This assumption is not always true even for the characters printed by IIJP. For solving this problem, we extended the idea of CCS to arbitrary located characters. Our method first generates character-region candidates based on local elliptical regions, named Fast-Hessian-Affine regions, and finds most likely character arrangement. Through experiments, we confirmed that our method quickly and accurately recognizes non-uniformly arranged characters.
