<i>gem</i>-Diborylalkanes: recent advances in their preparation, transformation and application (2018)

Recently, gem-diborylalkanes have attracted much attention as versatile building blocks and fundamental intermediates in organic synthesis, because they enable multiple C-C bond construction and further transformation at C-B bonds. Importantly, gem-diborylalkanes can be utilised as bisnucleophilic partners in a variety of chemo-selective C-C bond-forming reactions. This review describes recent developments in synthesising gem-diborylalkanes in complex molecules along with their chemical transformation. In the first part of the review the different synthetic approaches used to synthesise gem-diborylalkanes are described. In the second part, an overview of the chemoselective transformation of gem-diborylalkanes into various functionalized materials is discussed along with one-carbon homologation of diborylmethane via a selective uni- and bidirectional method.
Piloplex, a new long-acting pilocarpine polymer salt. B: Comparative study of the visual effects of pilocarpine and Piloplex eye drops. (1979)

Induced accommodation and changes in vision (distance and near) were measured monocularly and binocularly in 9 young healthy volunteers in a double blind study after administering to them pilocarpine hydrochloride 4%, Piloplex 3.4, and saline eye drop instillations. Piloplex 3.4, a new long-acting pilocarpine polymer salt, and pilocarpine hydrochloride 4% (both contain equal amounts of pilocarpine-3.4%) induced changes in vision and accommodation. These changes were greater with pilocarpine hydrochloride than with Piloplex. The maximum changes occurred half an hour after instillation and the effect vanished after an additional period up to 3 hours. The changes were greater when measured monocularly than binocularly. Piloplex initiates a prolonged hypotensive effect which lasts for 12 hours. Patients with glaucoma are thus able to use Piloplex on a twice-daily schedule. Consequently, visual disturbances occur only once a day in contrast to pilocarpine hydrochloride given 4 times a day, which induces 3 visual disturbances during the day.
[Use of the phenol fraction of Brucella for isolating a specific serum against Yersinia enterocolitica serovar O9]. (1985)

A phenol fraction, capable of adsorbing cross-reacting antibodies from Y. enterocolitica O9 antiserum without affecting its serological activity against specific antigens, has been obtained from a Brucella strain. The physicochemical and antigenic characteristics of the preparation are presented. It is recommended that the proposed method be tested in differentiation of intestinal yersiniosis caused by Y. enterocolitica O9 from Brucella infection. This work has resulted in obtaining highly specific antiserum to Y. enterocolitica, serovar O9.
Digital content management: the search for a content management system (2004)

Digital content management system is a software system that provides preservation, organization and dissemination services for digital collections. By adapting the systems analysis process, the University of Arizona Library analyzed its needs and developed content management system requirements for finding a suitable information system that addresses the increasing needs of digital content management. Dozens of commercial and open source candidates were examined to match against the requirements. This article provides detailed analysis of three major players (Greenstone, Fedora, and DSpace) in key areas of digital content management: preservation, metadata, access, and system features based on the needs of the University of Arizona Library. This paper describes the process used to analyze and evaluate potential candidates and includes results of analysis to illuminate the process.
Waveform optimal design for MISO space-based radar system (2009)

Based on space-borne multiple-input single-output radar systems, a novel orthogonal bi-phase coding waveform optimization design method is presented. However, it is impossible to design a set of codes with ideal impulsive autocorrelation and idea zero cross-correlation performances. Hence, only the shape of its main-lobe and side-lobe near the detected range cell is considered as the optimization criteria. The aperiodic correlation properties are discussed. Simulation results show that the proposed algorithm is effective and feasible.

Heat transfer measurements in a heated jet-pipe flow issuing into a cold cross stream (1983)

Measurements are presented of mean temperature in a nonbuoyant heated jet issuing perpendicularly into a cold stream at velocity ratios R=0.25, 0.5, 1, and 2, and of velocity-temperature fluctuation statistics at R=0.5. The mean temperature profiles at the jet exit are found to be considerably nonuniform at low velocity ratios, indicating an early mixing between the cold and hot fluid. The extra rate of strain due to streamline curvature and the longitudinal and normal temperature gradients affect the rate of generation of temperature fluctuations and turbulent heat fluxes. There are regions of the flow where the streamlines are unstably curved but the generation of ∼(ϑ2) is damped. The eddy diffusivity is well behaved across the flow only at downstream positions where the turbulent Prandtl number has rather high values close to the wall and reaches values around 0.9 away from the wall.
Synthesis of Dumbbell-Shaped Au−Ag Core−Shell Nanorods by Seed-Mediated Growth under Alkaline Conditions (2004)

We report a simple synthesis of Au-Ag core-shell nanorods (NRs) under alkaline conditions (pH 8.0-10.0) from silver and ascorbate ions using gold nanorods (GNRs) as the seeds. The silver ions that are reduced by the ascorbate ions become deposited on the surfaces of the GNRs to form differently dumbbell-shaped Au-Ag core-shell NRs and nanoparticles, depending on the pH and the concentration of silver ions. The longitudinal plasmon absorbance bands of the Au-Ag core-shell NRs are stronger and appear at shorter wavelengths than those for the original GNRs. We confirmed the formation of Au-Ag core-shell NRs by both energy-dispersive X-ray spectrometry and inductively coupled plasma mass spectrometry measurements, which indicate that the 109Ag/197Au ratios are 0.046, 0.085, and 0.097 at pH 8.0, 9.0, and 10.0, respectively. The transmission electron microscopy measurements show that the Au-Ag core-shell NRs are monodispersed (>90%).
Interfacial Adsorption of Polymers and Surfactants: Implications for the Properties of Disperse Systems of Pharmaceutical Interest (1999)

This review considers basic aspects of the interfacial adsorption of polymers and surfactants, with particular reference to the relevance of these processes for the formulation of pharmaceutical disperse systems. First, we discuss different approaches to the interpretation of adsorption isotherms, paying particular attention to systems containing more than one adsorbate. Second, we consider the implications of adsorption for the properties of suspensions, emulsions, and colloidal systems, particularly as regards the use of polymers and surfactants for stabilizing disperse systems, for controlling flocculation, and for modifying the biopharmaceutical behavior of colloidal drug carriers. Finally, we present a number of representative examples of the importance of adsorption of macromolecules in pharmaceutical systems.
Very high water permeability in vasopressin-induced endocytic vesicles from toad urinary bladder. (1989)

The regulation of transepithelial water permeability in toad urinary bladder is believed to involve a cycling of endocytic vesicles containing water transporters between an intracellular compartment and the cell luminal membrane. Endocytic vesicles arising from luminal membrane were labeled selectively in the intact toad bladder with the impermeant fluid-phase markers 6-carboxyfluorescein (6CF) or fluorescein-dextran. A microsomal preparation containing labeled endocytic vesicles was prepared by cell scraping, homogenization, and differential centrifugation. Osmotic water permeability was measured by a stopped-flow fluorescence technique in which microsomes containing 50 mM mannitol, 5 mM K phosphate, pH 8.5 were subject to a 60-mM inwardly directed gradient of sucrose; the time course of endosome volume, representing osmotic water transport, was inferred from the time course of fluorescence self-quenching. Endocytic vesicles were prepared from toad bladders with hypoosmotic lumen solution treated with (group A) or without (group B) serosal vasopressin at 23 degrees C, and bladders in which endocytosis was inhibited by treatment with vasopressin at 0-2 degrees C (group C), or with vasopressin plus sodium azide at 23 degrees C (group D). Stopped-flow results in all four groups showed a slow rate of 6CF fluorescence decrease (time constants 1.0-1.7 s for exponential fit) indicating a component of nonendocytic 6CF entrapment into sealed vesicles. However, in vesicles from group A only, there was a very rapid 6CF fluorescence decrease (time constant 9.6 +/- 0.2 ms, SEM, 18 separate preparations) with an osmotic water permeability coefficient (Pf) of greater than 0.1 cm/s (18 degrees C) and activation energy of 3.9 +/- 0.8 kcal/mol (16 kJ/mol). Pf was inhibited reversibly by greater than 60% by 1 mM HgCl2. The rapid fluorescence decrease was absent in vesicles in groups B, C, and D. These results demonstrate the presence of functional water transporters in vasopressin-induced endocytic vesicles from toad bladder, supporting the hypothesis that water channels are cycled to and from the luminal membrane and providing a functional marker for the vasopressin-sensitive water channel. The calculated Pf in the vasopressin-induced endocytic vesicles is the highest Pf reported for any biological or artificial membrane.
The Radiosensitivity of Kidney Colony-Forming Cells: A Short-Term Assay in Situ in the Mouse (1989)

A short-term colony assay for renal tubule epithelium has been developed. Uranyl nitrate (UN) is a heavy metal nephrotoxin that induces acute tubule necrosis followed by a large compensatory increase in the rate of cell proliferation in the nephron. UN was used to precipitate latent damage following renal irradiation. Using a subcapsular colony count at 14 days after unilateral irradiation, a single-dose cell survival curve was obtained with a D0 of 4.2 +/- 0.3 Gy. High-dose irradiation of an exteriorized kidney resulted in a survival curve which was biphasic, with a plateau in survival between 18 and 40 Gy. Subtraction of this plateau level from all the survival data gave D0 values of 2.5 +/- 0.2 Gy (data analyzed between 7.5 and 16 Gy) or 2.0 +/- 0.2 Gy (over range 12-16 Gy). The D0 value obtained at 20 months after bilateral (or unilateral) kidney irradiation, without the use of UN, was 2.9 +/- 1.1 Gy (over range 10-14 Gy).

Quae cum Balbus dixisset, turn arridens Cotta, Sero, inquit, milii, Balbe, praecipis, quid defeudam. Ego enim te disputante, quid contra dicerem, mecum ipse meditabar, neque tarn refellendi tui causa quam ea, quae minus intellegebani, requirendi. Cum autem suo cuique judicio sit utendum, difficile factu est me id sentire, quod tu velis. Hie Velleius, Nescis, inquit, quanta cum exspectatione, Cotta, sim te auditurus. Jucundus enim Balbo nostro sermo tuus contra Epicurum fuit; praebebo igitur ego me tibi vicissim attentum contra Stoicos auditorem. Spero enim te, ut soles, bene paratum venire. Turn Cotta, Sic mehercule, inquit, Vellei; neque enim mihi par ratio cum Lucilio est ac tecum fuit. Qui tandem? inquit ille. Quia mihi videtur Epicurus vester de dis immortalibus non magnopere pugnare; tantum modo uegare deos esse non audet, ne quid invidiae subeat aut criminis. Cum vero deos nihil agere, nihil curare confirmat membrisque humanis esse praeditos, sed eorum membrorum usum nullum habere, ludere videtur satisque putare, si dixerit esse quandam beatam naturam et aeternam. A Balbo autem animadvertisti, credo, quam multa dicta sint quamque, etiam si minus vera, tamen apta inter se et cohaerentia. Itaque cogito, ut dixi, non tarn refellere ejus orationem quam ea, quae minus intellexi, requirere. Quare, Balbe, tibi permitto, responderene mihi malis de singulis rebus quaerenti ex te ea, quae parum accepi, an universam audire orationem meam.

Received Signal Strength Indicator-Based Adaptive Localization Algorithm for Indoor Wireless Sensor Networks (2013)

Abstract: Solutions for indoor localization have become more critical with recent advancement in context and location-aware technologies. When wireless sensor network (WSN) used in complex indoor environment, great propagation loss will be caused and it is very difficult to estimate adaptively the location of target nodes when environment changed. In this paper, an indoor adaptive localization algorithm based on received signal strength indication (RSSI) for wireless sensor networks is proposed. The algorithm utilizes the RSSI of radio signals radiating from two other fixed nodes to generate the local parameters of signal propagation model for each fixed node, and the parameters are updated online according to environmental variation. According to the estimated parameters of the signal propagation model, iteration method is applied to estimate the position of target node. Through actual experimental tests, the validity of the proposed algorithm is demonstrated. Copyright © 2013 IFSA.
A Framework for Learning from Distributed Data Using Sufficient Statistics and Its Application to Learning Decision Trees (2004)

This paper motivates and precisely formulates the problem of learning from distributed data; describes a general strategy for transforming traditional machine learning algorithms into algorithms for learning from distributed data; demonstrates the application of this strategy to devise algorithms for decision tree induction from distributed data; and identifies the conditions under which the algorithms in the distributed setting are superior to their centralized counterparts in terms of time and communication complexity; The resulting algorithms are provably exact in that the decision tree constructed from distributed data is identical to that obtained in the centralized setting. Some natural extensions leading to algorithms for learning from heterogeneous distributed data and learning under privacy constraints are outlined.
A Thermal Tactile Display Device with Multiple Heat Sources (2012)

A compact thermal tactile display device with multiple heat sources is proposed in this paper. The device has a 3×3 display units array and a Peltier module. In every display unit, a wire-twined resistance is used as heat component, a minitype NTC thermistor is used as temperature sensor, and an aluminum column is used as heat conduction component for contacting. The Peltier module is used to cool the display units array. Finally, the device was installed on the hand controller, allowing operators to manipulate virtual hand to touch the heat sources in the virtual environment, and its thermal tactile display property was tested. The results showed that the thermal tactile device can display the temperature from 5°C to 55°C, and different temperature field distribution can be displayed on the contact surface of the 3×3 array.
Enhanced P1500 compliant wrapper suitable for delay fault testing of embedded cores (2004)

Continual advances in the manufacturing processes of integrated circuits provide designers the ability to create more complex and denser architectures and increased functionality on a single chip. The increased usage of embedded cores necessitates a core-based test strategy in which cores are also tested separately. The IEEE P1500 proposed standard for embedded core test (SECT) is a standard under development which aims is to improve the testing of core-based system chips. This paper deals with the enhancement of the test wrapper and wrapper cells to provide a structure to be able to test embedded cores for delay faults. This approach allows delay fault testing of cores by using the digital oscillation test method and the help of the enhanced elements while staying compliant to the P1500 standard.
Use of on-line UV/Vis-spectrometry in the measurement of dissolved ozone and AOC concentrations in drinking water treatment (2008)

The concentrations of dissolved ozone and assimilable organic carbon (AOC) are important performance parameters in drinking water production. For the measurement of ozone, a spectral algorithm was developed that allows quantification in situ using a UV/Vis spectrometer probe. Furthermore, a strong correlation between the change in the absorption spectrum after individual treatment steps and the formation or removal of AOC in that treatment step was observed. This allowed the development of a spectral algorithm that predicts AOC formation during ozonation and subsequent removal in further treatment steps. This method has been verified at one pilot plant of the Amsterdam drinking water supply.
An investigation of the educational needs of health sciences library manpower. 3. Manpower supply and demand in health sciences libraries. (1971)

An investigation of the manpower requirements of health sciences libraries and of educational programs appropriate to these manpower needs was begun in March 1968. To date, 4,727 libraries have been identified as being used by 14,000 health sciences institutions and programs. Of this total, 2,628 are hospital libraries; 1,328 are health sciences libraries and collections located outside of hospitals; and 771 are academic or public libraries. Within these libraries some 14,938 persons are directly involved, either full- or part-time, in the delivery of health sciences library services. Of the total work force, 5,861 persons are employed in hospital libraries and 9,077 are employed in health sciences libraries and collections. The ratio between professional and nonprofessional employees is 1:2; professional and nonprofessional status was assigned by the chief librarian. Survey data indicate a 7 percent manpower shortage in positions classified as professional, and a 3 percent shortage in positions classified as nonprofessional.
User Profile-Based Authorization Policies for Network QoS Services (2008)

Recent papers propose QoS solutions allowing the users to explicitly specify the quality level they request during a so-called explicit QoS service invocation that includes dynamic QoS offering and new mechanisms for authentication, authorization and accounting. In particular, organizations should be able to control their network services and authorize QoS services based on service parameters, as destination addresses, applications and employees’ roles. Therefore, user profile-based authorization policies for explicit QoS service invocations should be adopted. Each user profile indicates the services that the user is authorized to request, their consumption limits and scope. This paper deals with the authorization of explicit QoS services invocations and proposes a user profile model for profile-based authorization of QoS services.
Dynamic Lane Grouping at Isolated Intersections: Problem Formulation and Performance Analysis (2012)

This paper presents some fundamentals of the dynamic lane grouping (DLG) concept, the aim of which is to improve lane utilization under variations in traffic demand. The problem was formulated as a mathematical programming model to determine the optimal lane allocation of an isolated intersection in relation to minimizing the maximum lane flow ratio (defined as the assigned flow divided by the saturation rate). Shared lanes and user equilibrium status for lane use were also considered in the model. Numerical analyses were conducted for four cases with different numbers of lanes, saturation levels, and methods for setting signal timing (adaptive and fixed timing). The results indicated that DLG might provide significant performance improvement in reducing the maximum-flow ratio under the spatial variation in demand. The performance of DLG was also compared with real-time adaptive signal timing by means of the average delay; improvements to the average delay were also observed when the spatial variation was large. The maximum-flow ratio and the average delay of DLG remained almost unchanged for the full spectrum of spatial demand variation when total demand was constant. The results also implied that the more significantly the demand varied, the more benefits the dynamic lane grouping method could potentially provide.
Overview of the Mceliece Cryptosystem and its Security (2014)

Abstract McEliece cryptosystem (MECS) is one of the oldest public key cryptosystems, and the oldest PKC that is conjectured to be post-quantum secure. In this paper we survey the current state of the implementation issues and security of MECS, and its variants. In the first part we focus on general decoding problem, structural attacks, and the selection of parameters in general. We summarize the details of MECS based on irreducible binary Goppa codes, and review some of the implementation challenges for this system. Furthermore, we survey various proposals that use alternative codes for MECS, and point out some attacks on modified systems. Finally, we review notable existing implementations on low-resource platforms, and conclude with the topic of side channels in the implementations of MECS
