Magnesium Versus Zinc Coordination to Multidentate Schiff Base Ligands (2001)

The reactions of two mononuclear zinc complexes, [Zn(HL1)(H2O)2], 1, and [ZnL4(H2O)], 7, (H3L1 = Schiff base derived from 3-formylsalicylic acid and glycine, H2L4 = Schiff base derived from 2,6-diformyl-4-methylphenol and 1,2-diaminoethane), with Mg2+ has been studied. These complexes contain binucleating Schiff base ligands and have vacant coordination sites. For both compounds, substitution of zinc by magnesium has been observed in DMSO. Likewise, the Zn complex of H2L2 (Schiff base derived from salicylaldehyde and glycine) can be converted into the corresponding Mg compound. The following complexes were characterized by single-crystal X-ray analysis: [MgL3(H2O)3], 4, [MgL2(H2O)2]n, 5, [Mg(sal)2(H2O)2], 6, and [MgL4(H2O)(CH3OH)], 8 (H2L3 = Schiff base derived from 5-bromosalicylaldehyde and glycine, Hsal = salicylaldehyde). The tri- and tetradentate N,O ligands H2L3 and H2L4 form discrete complex molecules in the solid state, while a carboxylate-bridged polymeric structure is formed by H2L2. In 4 and 8 the aqua ligands hydrogen bond with the deprotonated phenolate and carboxylate oxygen atoms, resulting in the formation of dimers. In 6 two aqua ligands, two phenolate oxygens and two aldehyde oxygens give rise to an O6 coordination sphere.
Efficacy of vaccination and antimicrobial treatment to eliminate chronic intramammary Staphylococcus aureus infections in dairy cattle (2006)

Results indicate that a combination of vaccination and antimicrobial treatment can be successful in eliminating some cases of chronic intramammary S aureus infections in dairy cattle. However, it is important to consider extended treatment protocols carefully because many cows are likely to remain infected with S aureus despite treatment and vaccination.
An e-mail-based bibliographic information server (1994)

The National Centre for Science Information (NCSI), of the Indian Institute of Science (IISc), provides var ious computer-based information services to the researchers and scientists in academic and research and development (R & D) institutions in India. Foremost among them is the selec tive dissemination of information (SDI) service, provided in five different disciplines, using the appropriate abstracting/ indexing periodicals published by international bibliograhic agencies in computer-readable form on magnetic tapes. NCSI came on the e-mail network ERNET (Education and Research Network) - India's academic computer network - when its computer system, that runs under the UNIX environment, was connected to IISc's e-mail node through the campus- wide fibre optic network. With a view to providing better access to the bibliographic data which NCSI regularly acquires on tapes, an information server, bibserv, was devel oped that can be made available over ERNET from NCSI's computer system. An information server, or infoserver for short, is software that receives queries in predefined format by e-mail, executes the commands therein by searching the database and sends back the retrieved information or files by e-mail. The infoserver, bibserv, performs these operations on a bilbliographic database. It has the capabilities of: reading the mailbox to obtain the return address and the message lines from each mail arrived; parsing each line of the mes sage, which forms a command for the server, and executing the command if it falls within its set of built-in commands. The built-in commands are: help, which sends a help mes sage containing information on how to use the infoserver through e-mail; find, which finds and shows the number of records retrieved in response to a Boolean query; send, which sends the references and abstracts retrieved from the Boolean search executed, and list, which lists a page from the index of the database starting with a given keyword. To use bibserv, one can send an e-mail to bibserv@ncsi. iisc. ernet. in with one or more commands in the message body. Problems or queries relating to bibserv that require human intervention can be sent to help@ncsi. iisc. ernet. in. The bibserv software is written in the C language and implemented under UNIX System V Release 3.0. The search and retrieval modules that are developed for running the SDI service are utilised for bib serv. Sending the output file as the reply mail is imple mented by using system calls to one of the mail programs of the UNIX system. This paper describes the development and implementation of the bibserv software.
Repairing GUI Test Suites Using a Genetic Algorithm (2010)

Recent advances in automated functional testing of Graphical User Interfaces (GUIs) rely on deriving graph models that approximate all possible sequences of events that may be executed on the GUI, and then use the graphs to generate test cases (event sequences) that achieve a specified coverage goal. However, because these models are only approximations of the actual event flows, the generated test cases may suffer from problems of infeasibility, i.e., some events may not be available for execution causing the test case to terminate prematurely. In this paper we develop a method to automatically repair GUI test suites, generating new test cases that are feasible. We use a genetic algorithm to evolve new test cases that increase our test suite's coverage while avoiding infeasible sequences. We experiment with this algorithm on a set of synthetic programs containing different types of constraints and for test sequences of varying lengths. Our results suggest that we can generate new test cases to cover most of the feasible coverage and that the genetic algorithm outperforms a random algorithm trying to achieve the same goal in almost all cases.
FIVE-COORDINATED COMPLEXES CONTAINING AN OPTICALLY ACTIVE LIGAND (1980)

Abstract Copper(II), nickel(II), and cobalt(II) complexes containing (+)546-2-[bis(dimethylaminoethyl)amino]-1-propanol were prepared. The CD spectra of these complexes in nitromethane were measured between 10000–26000 cm−1.
Mononuclear salen-gallium complexes for iso-selective ring-opening polymerization (ROP) of rac-lactide (2017)

A series of mononuclear salen-supported gallium amido/alkoxide derivatives were prepared and structurally characterized and subsequently used as initiators in rac-lactide ring-opening polymerisation (ROP). The reaction of variously substituted salen ligands (1a-1f) with 0.5 equiv. of Ga<sub>2</sub>(NMe<sub>2</sub>)<sub>6</sub> allowed the isolation of the corresponding (salen)Ga-NMe<sub>2</sub> chelates (2b-2d, 2f) via an amine elimination route, as poorly soluble compounds in common solvents. The (salen)Ga-OBn derivatives (3a-3e) may be readily accessed by an amine-elimination/alcoholysis sequence and the molecular structures of 3a, 3d and 3e were confirmed through X-ray crystallography diffraction analysis. The present (salen)Ga-X species may effectively mediate the iso-selective ROP of rac-LA in a controlled manner (P<sub>m</sub> up to 0.77 using a 1/1 2f/BnOH mixture as ROP initiator), with a ROP activity greatly dependent upon steric hindrance and geometrical constraints imposed by the variously substituted salen ligands. Based on the present study, salen ligands with limited steric hindrance and a certain degree of flexibility appear best suited for iso-selective ROP by (salen)Ga chelates. The salen-gallium complex 3a is also effective for the controlled ROP of ε-caprolactone (CL) and the production of PCL-b-PLA copolymers.
Experimental Investigation of the Wet Oxidation Destruction of Shipboard Waste Streams (1974)

Increasingly stringent water quality regulations anticipate the need for treating all shipboard waste streams containing combustible matter. Wet air oxidation or pressurized aqueous combustion conducted at 475 to 600F at operating pressures from 600 to 1850 pounds per square inch gage was investigated as one means for the ultimate destruction of organic wastes. This process was investigated by conducting experiments in a 1-gallon pressure vessel with a variety of wastes under different conditions. Waste types used in the experiments were sanitary, food, oil, municipal sludge, glucose, and cellulose. Results showed that the wet oxidation process obeys first-order kinetics consisting of two separate and distinct reactions. Catalysts have their main influence on the fast reaction, increasing its rate by a factor of three. Additional removal of organic matter can be achieved by further processing the wet oxidation effluent through a reverse osmosis membrane. (Modified author abstract)
Analyses of jitter suppression for digital transmission system with filter-less clock recovery (2004)

New behaviors of jitter generation and accumulation in a chain of repeaters are investigated for digital transmission systems with filter-less clock recovery. It is shown that considerable jitter accumulation is encountered in such systems. Alleviating jitter accumulation by minimal Q filtering is analyzed.
Performance assessment of DPSK soliton transmissionsystem (2001)

An optical communication system using solitons and a coding/multiplexing scheme based on differential phase-shift keying and optical delays is proposed. The performance of such a system is analysed theoretically, based on the soliton optical phase jitter that occurs in an amplified link, and measured in a recirculating loop experiment.
Three-phase, two-switch PFC rectifier fed three-level VSI based FOC of induction motor drive (2012)

This paper presents a Scott transformer based three-phase, two-switch PFC (Power Factor Correction) boost rectifier for improving the power quality in a three-level diode clamped inverter (DCI) feeding indirect rotor field oriented control (FOC) based induction motor drive (IMD). Sinusoidal unity power factor source current and dc-link voltage regulation are achieved in the proposed rectifier only with two-switches. The three-level DCI is supplied by a split dc-link obtained from a Scott connected transformer feeding a rectifier. It is shown that a three-level DCI achieves reduced stator current with lower voltage harmonic content even at a lower switching frequency as compared to a two-level inverter. This results in reduction of voltage stress on motor windings for the same amount of torque ripple when indirect rotor FOC algorithm is implemented for the IMD. A MATLAB based simulation model of proposed PFC rectifier is developed for validating the design and to verify that the power quality issues in three-level DCI fed IMD are adequately addressed. The performance of the system is studied and compared with a conventional diode rectifier fed vector controlled IMD for different operating conditions of the drive.
[Targeted therapy for cancer: anti-tyrosine kinase receptor agents]. (2007)

The use of drugs to treat cancer based on molecular targets is common fact, especially those targeting kinases that are involved in the cellular signalling pathways. The anti-tyrosine receptor drugs are among the most developed, some of them having already been approved by the FDA and the EMEA for breast cancer, colorectal, lung GIST and renal cancer treatment. Although these drugs are currently focused on a single target, the future challenge is to hit several targets simultaneously, along with combined chemotherapy. Thus we are facing the beginning of a new era in the battle against cancer.
Camera Calibration and Selective Tracking of a Moving Object by the Collaboration of Multiple Cameras (2003)

We discuss a system which utilizes the collaboration of multiple cameras and traces moving objects specified by a user. Three-dimensional shape reconstruction and collaborative tracking of objects require a camera calibration to evaluate the position and orientation of each camera. We introduce a dynamic camera calibration method which lets more than one camera to track a moving object simultaneously and evaluates calibration data. The method is incorporated with our object-tracking system using multiple cameras, and its validity is confirmed.
Zero offset drift suppression in SiC pressure sensors at 600 (2010)

Temporal drifts in zero pressure offset voltage, V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oz</sub> , observed in piezoresistive silicon carbide (SiC) pressure sensors at 600 °C were significantly suppressed to allow reliable operation. By modifying the bondpad/contact metallization, the Vη relative drift velocity at 600 °C was suppressed to within ± 0.5 mV.hr <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> , for over 1000 hours. Microstructural changes within the contact metallization were analyzed with Auger Electron Spectroscopy (AES) and Scanning Electron Microscopy (SEM). This metallization scheme may improve SiC pressure sensor reliability in short duration ground/flight tests and lower temperature (~300 °C) remote pressure monitoring (i.e., geothermal, and deep well drilling).
A decision-based approach to rhetorical parsing (1999)

We present a shift-reduce rhetorical parsing algorithm that learns to construct rhetorical structures of texts from a corpus of discourse-parse action sequences. The algorithm exploits robust lexical, syntactic, and semantic knowledge sources.
Proposed Fracture Theory of a Dispersion‐Strengthened Glass Matrix (1966)

A fracture theory is proposed for a composite system based on a continuous glass matrix. It is hypothesized that hard crystalline dispersions within the glass matrix will limit the size of Griffith flaws and strengthen the composite. Quantitative relations are derived for the effect of a dispersed phase on composite strength. At low volume fractions of the dispersed phase, the average flaw size is statistically reduced independent of the size of the dispersed particles. At high volume fractions of the dispersed phase, the average flaw size is governed by the average distance between particles dispersed in the matrix. The strength of a composite should, therefore, be a function of the volume fraction of the dispersed phase at low volume fractions and dependent on both the volume fraction and particle size of the dispersed phase at high volume fractions. For verification of the theory, cross‐bending strengths were measured on a sodium borosilicate glass containing varying volume fractions of spheroidized alumina over a range of particle sizes. The average distance between dispersed particles ranged from approximately 15 to 500μ. Good agreement with theory was found. Values of glass surface energy calculated from the experimental data agree well with literature data.
Affective ranking of movie scenes using physiological signals and content analysis (2008)

In this paper, we propose an approach for affective ranking of movie scenes based on the emotions that are actually felt by spectators. Such a ranking can be used for characterizing the affective, or emotional, content of video clips. The ranking can for instance help determine which video clip from a database elicits, for a given user, the most joy. This in turn will permit video indexing and retrieval based on affective criteria corresponding to a personalized user affective profile.
Optimal implementation of sea of leads (SoL) compliant interconnect technology (2004)

Compliant interconnects can enable wafer level packages with high I/O density, high reliability and better performances with low cost and small size. A fabrication process for SoL compliant interconnects has been optimized to achieve high yield and compatibility with standard back-end-of-line (BEOL) as well as flip-chip bonding processes. The optimized fabrication process further enables a reliable joining between the IC and SoL compliant interconnects to the next level of packaging without the use of an expensive underfilling process.
Exacerbation of invasive aspergillosis by the immunosuppressive fungal metabolite, gliotoxin (1996)

Invasive aspergillosis is a significant cause of death in immunocompromised individuals. The majority of strains of the main causative agent, Aspergillus fumigatus, produce gliotoxin, a secondary metabolite with demonstrated in vitro immunosuppressive activity. Pretreatment of normally resistant mice with a single injection of a sublethal dose of gliotoxin was sufficient to make them susceptible to infection and subsequent death, after challenge with A. fumigatus spores. Animals infected with the non-gliotoxin producing strain survived significantly longer than those infected with a gliotoxin producer. We propose that the release of gliotoxin by A. fumigatus hyphae during infection can exacerbate the pathogenesis of aspergillosis.
Dose Rate Effects on Radiolytic Synthesis of Gold−Silver Bimetallic Clusters in Solution (1998)

Radiolysis of mixed AuIII/AgI solutions at different dose rates is examined. The progressive evolution with dose of the UV−visible absorption spectra of radiation-induced metal clusters is discussed and compared with those calculated by Mie theory. The clusters have been also observed by transmission electron microscopy and analyzed by X-ray microanalysis and diffraction. At low dose rate, reduced silver atoms transfer an electron to gold ions (either free or at the surface of aggregates). Then, when AuIII ions are totally reduced, reduction of the silver ions occurs in a second step at the surface of gold clusters, and silver-coated gold aggregates are obtained. At high dose rate, the shape of the absorption spectrum does not change with an increase in the absorbed dose and X-ray microdiffraction confirms that bimetallic alloyed Ag/Au clusters are synthesized. These results imply the preponderant influence of kinetics in the competition between the reduction−coalescence processes and intermetallic electron transfer. The segregation or the alloying of the metals is controlled by the reduction rate; a fast total reduction of both types of metal ions prevents the redox equilibrium through electron transfer from being established. A perfectly ordered nanocrystal, as observed by electron microdiffraction, also implies an intimate association of metal atoms from the early steps of reduction and aggregation.
Inductive detection of piezoelectric resonance by using a pulse NMR/NQR spectrometer (1989)

An inductive excitation and detection scheme of piezoelectric resonance is shown using a conventional pulse NMR/NQR spectrometer and its associated experimental techniques. This new method has advantages over the previous capacitive scheme since the measurement does not require any electrode to be attached to the sample. For a test we investigated the piezoelectric resonance observed inductively from a 3.5-MHz AT-cut quartz crystal.
FIFTY YEARS ON - LOOKING BACK AT DEVELOPMENTS IN METHODS OF BLOOD- AND BREATH-ALCOHOL ANALYSIS (2000)

Exactly 50 years ago at the T-1950 conference in Stockholm, a new principle was introduced for measuring alcohol in biological specimens. This involved the oxidation of ethanol with an enzyme called alcohol dehydrogenase (ADH), which had been extracted and purified from horse liver. The ADH method was more sensitive and selective for measuring ethanol than the wet-chemistry oxidation procedures used during the first half of the century. Breath tests for alcohol were given a boost when Borkenstein developed the Breathalyzer in 1954. Breath testing for alcohol influence became widely used for traffic law enforcement purposes in USA, Canada, and Australia. In European countries blood and urine were the preferred specimens for forensic alcohol analysis and by the early 1960s the method of gas chromatography (GC) appeared including the headspace sampling technique, which was perfect for analyzing volatile substances in body fluids. Interest in Europe shifted towards evidential breath-alcohol testing in the 1980s, which coincided with the introduction of new analytical technology for sampling and analysis of breath, such as compact infrared (IR) spectrometers controlled by microprocessors. In the 1970s, electrochemical oxidation of alcohol with fuel cell devices became popular and these were incorporated into hand-held instruments suitable for roadside screening of motorists. Recent improvements in this kind of technology have meant that fuel cells are being used for evidential breath-alcohol testing. Whether breath-alcohol devices utilizing gas chromatography and mass spectrometry (GC-MS) or Fourier transform infrared spectrometry (FTIR) will emerge to provide the ultimate way of identifying ethanol in blood and breath samples for forensic purposes remains to be seen. One goal for the new millennium, at least in some countries, seems to be the use of evidential breath-alcohol testing at the roadside. This saves much time and resources for the police and also reduces the number of false-positive roadside alcohol screening tests. For the covering abstract see ITRD E106992.
Hepatitis B and cancer: A practical guide for the oncologist (2015)

Hepatitis B virus (HBV) infection is a worldwide disease associated with significant morbidity and mortality and after acute infection, HBV infection can persist in about 1-2% of immunocompetent hosts. Chemotherapy-induced immunosuppression can lead to HBV reactivation and may cause discontinuation of anticancer treatment, fulminant hepatitis with liver failure and death. During immunosuppressive treatments such as chemotherapy, reactivation of HBV infection is a life-threatening complication that can occur in HBV active or inactive carriers but also in patients with OBI. Occult HBV infection (OBI) is defined as the presence of detectable very low levels of HBV DNA in HBsAg-negative patients. Many literature data showed a benefit from prophylactic antiviral treatment in cancer patients at risk for HBV reactivation, however there is no evidence in determining the benefit of routine screening for chronic HBV infection in all patients undergoing cytotoxic and immunosuppressive chemotherapy. Major guidelines recommend HBV screening in HBV-infection high risk patients or if the immunosuppression caused by the treatment is expected to be high.

The significance of axillary sentinel lymph node biopsy after neoadjuvant chemotherapy (2009)

Objective Comparing the influence of neoadjuvant chemotherapy on sentinel lymph node biopsy and axillary lymph nodal staging. Methods From June 2005 to June 2007 one hundred and sixty five breast cancer patients of stage Ⅰ,Ⅱa,Ⅱb and Ⅲ underwent sentinel lymph node biopsy(SLNB) using 99mTc combining methylene blue dye as tracer to help axillary lymph node dissection(AND) were retrospectively reviewed. Sixty five patients staged Ⅱb or Ⅲ were treated with three circles neoadjuvant chemotherapy prior to SLNB and AND , another one hundred patients staged ⅠorⅡa had SLNB and AND directly without neoadjuvant chemotherapy.Results Average 14.60 axillary lymph nodes were retrieved in patients had neoadjuvant chemotherapy and 14.74 lymph nodes in patients did not have neoadjuvant chemotherapy(P>0.05),a mean number of 1.46 sentinel lymph nodes in neoadjuvant chemotherapy group and 1.5 sentinel lymph nodes in non-neoadjuvant chemotherapy(P>0.05), sentinel lymph node identification rate 96.9% in neoadjuvant chemotherapy group and 97% in non-neoadjuvant chemotherapy(P>0.05), the false negative rate was 4.6% in neoadjuvant chemotherapy group and 4% in non-neoadjuvant chemotherapy group(P>0.05). Conclusions The mean number of lymph nodes,sentinel lymph nodes,SLN identification rate and false-negative rates after neoadjuvant chemotherapy are similar to those seen in patients without neoadjuvant chemotherapy.The SLNB can accurately predict lymph node status of axillary lymph node following neoadjuvant chemotherapy.
