Solobacterium moorei Bacteremia: Identification, Antimicrobial Susceptibility, and Clinical Characteristics (2011)

We present five cases of Solobacterium moorei bacteremia. The isolates were identified with 16S rRNA gene sequencing and were susceptible to common antibiotics used for anaerobic infections. Bacteremia with S. moorei seems to be associated with debilitating conditions, but the prognosis of the infection appears to be good.
Kinetic properties of the pentobarbitone‐gated chloride current in frog sensory neurones. (1987)

1. The kinetic properties of the activation and inactivation (desensitization) phases of pentobarbitone (PB)-induced inward Cl- current (ICl) were studied in isolated frog sensory neurones, following suppression of Na+, K+ and Ca2+ currents, using the concentration jump technique which combines the internal perfusion and the rapid exchange of the external solutions surrounding a neurone with time constants of 2-3 ms. The results were compared with those of the gamma-aminobutyric acid (GABA)-gated ICl. 2. The PB dose-response curve was bell-shaped and the maximum peak value was less than the current induced by 1.7 X 1.5(-5) M-GABA, the concentration at which GABA evoked a half-maximum response. 3. The activation and inactivation phases of PB-induced ICl consisted of double-exponential, fast and slow components, respectively. The time constant of the fast component (tau af) of the activation was relatively stable in a concentration range between 3 X 10(-4) and 6 X 10(-3) M. The time constant of the slow component (tau as) of the activation decreased with increasing PB concentrations. Both the fast and slow components (tau if and tau is) of the inactivation decreased with increasing PB concentrations. 4. Over a wide range of concentrations the tau af and tau as values of the PB-induced ICl were 10-30 times greater than the respective values of GABA-induced ICl. 5. At concentrations below 10(-3) M the PB-induced ICl was voltage dependent at more negative potentials than -20 mV. 6. The PB-induced ICl was blocked by bicuculline and by picrotoxin, but in a different manner. Bicuculline increased the time constants of the activation and inactivation. Picrotoxin had little effect on the activation phase but markedly facilitated the inactivation phase. 7. High concentrations of PB (over 10(-3) M) led to a decline in both the peak and plateau currents of the PB-induced ICl. A transient 'hump' current appeared with wash-out of the external solutions containing high concentrations of PB. This hump current was blocked by bicuculline in a dose-dependent manner. 8. The results suggest the possibilities that the PB receptor-ionophore complexes consist of at least two different components having different affinities and kinetics and that the PB and GABA binding sites are closely located.

Formation of GaAs nanocrystals by laser ablation (2001)

The pulsed laser ablation method has been used to form GaAs nanocrystals. A quadrupled frequency Nd:yttrium–aluminum–garnet laser beam is focused onto a GaAs single crystal target, and a nitrogen flowing gas is sent at the neighborhood of the target in order to transfer in an ethanol bath, the nanoparticles grown in gas phase. The composition of the particles is close to stoichiometry and transmission electron microscopy analyses highlight zinc-blende GaAs nanocrystals with a rather well defined size: 5–8 nm diameter. The low temperature photoluminescence and photoluminescence excitation spectra show quantum confinement of about 870 meV via an emission band in the visible range (500–560 nm) for the GaAs nanocrystals produced by laser ablation without any postannealing treatment.
Primary structure of alpha-clostripain light chain (1984)

The primary structure of light chain of alpha-clostripain was determined by sequence analysis of peptides derived from tryptic digests purified by reverse-phase high-performance liquid chromatography. The 22 isolated tryptic peptides were aligned by peptides derived from chymotryptic and staphylococcal V8 proteinase digests. The light chain contains 133 amino acids residues and has a relative molecular mass of 15400. The prediction of its secondary structure is given.
Vestibulo-Ocular Reflex (2007)

The vestibulo-ocular reflex (VOR) ensures best vision during head motion by moving the eyes contrary to the head to stabilize the line of sight in space. The VOR has three main components: the peripheral sensory apparatus (a set of motion sensors: the semicircular canals, SCCs, and the otolith organs), a central processing mechanism, and the motor output (the eye muscles). The SCCs sense angular acceleration to detect head rotation; the otolith organs sense linear acceleration to detect both head translation and the position of the head relative to gravity. The SCCs are arranged in a push-pull configuration with two coplanar canals on each side (like the left and right horizontal canals) working together. During angular head movements, if one part is excited the other is inhibited and vice versa. While the head is at rest, the primary vestibular afferents have a tonic discharge which is exactly balanced between corresponding canals. During rotation, the head velocity corresponds to the difference in the firing rate between SCC pairs. Knowledge of the geometrical arrangement of the SCCs within the head and of the functional properties of the otolith organs allows to localize and interpret certain patterns of nystagmus and ocular misalignment. This is based on the experimental observation that stimulation of a single SCC leads v ia the VOR to slowphase eye movements that rotate the globe in a plane parallel to that of the stimulated canal. Furthermore, knowledge of the mechanisms that underlie compensation for vestibular disorders is essential for correctly diagnosing and effectively managing patients with vestibular disturbances.
Review on screen printed metallization on p-type silicon (2012)

Advanced solar cell contacts feature local contacts to p- and p+- Si. In this review existing models for contact formation to p and p+-Si are presented. The formation of the local Al BSF as applied in PERC like solar cell structures is inhibited by the formation of voids. It is shown that the formation of voids depends on process parameters and their influence on the contact formation is reviewed. Using an analytical model it is possible to predict the depth of the resulting Al BSF in dependence of the contact geometry and the peak firing temperature. Contact formation to B doped Si with pure Ag paste results in high contact resistances whilst contact formation to Al doped Si with Ag paste is less difficult. The contact formation with Ag paste to B doped Si is enhanced by the addition of Al to the Ag paste.
Enantioselective α-Trifluoromethylation of Aldehydes via Photoredox Organocatalysis (2009)

The first enantioselective, organocatalytic alpha-trifluoromethylation and alpha-perfluoroalkylation of aldehydes have been accomplished using a readily available iridium photocatalyst and a chiral imidazolidinone catalyst. A range of alpha-trifluoromethyl and alpha-perfluoroalkyl aldehydes were obtained from commercially available perfluoroalkyl halides with high efficiency and enantioselectivity. The resulting alpha-trifluoromethyl aldehydes were subsequently shown to be versatile precursors for the construction of a variety of enantioenriched trifluoromethylated building blocks.
Recognizing abruptly changing facial expressions from time-sequential face images (2002)

This paper proposes a method that can spot and recognize each facial expression. From time-sequential images that contain multiple facial expressions that could abruptly change from one expression to another expression. Previously, the authors have proposed an HMM (Hidden Markov Models) based method for recognizing a spotted facial expression. In this paper to HMM, we add states corresponding to the simultaneous motion of two different facial expressions: i.e. a muscle relaxation for one expression and a muscle contraction for another expression. Then, the added states are each lined from the HMM apex state of one expression and are linked to that of another expression. Experimental results showed that for most pairs of expressions the change in expression can be recognized accurately. In addition, recognition rate for very fast change of expressions improved significantly. The proposed method was applied to regenerate facial expressions on a synthesized character to show the method's effectiveness in obtaining facial motion information.

We have measured the upper critical field ${B}_{c2}$(T) of ${\mathrm{Y}}_{2\mathrm{\ensuremath{-}}\mathrm{x}}$${\mathrm{Ba}}_{\mathrm{x}}$${\mathrm{CuO}}_{4\mathrm{\ensuremath{-}}\mathrm{y}}$ with x=0.4 near ${T}_{c}$ in dc fields up to 20 T and at 77 K with pulsed fields to 45 T. The data yield (${\mathrm{dB}}_{c2}$/dT${)}_{T={T}_{c}}$=1.3 T/K and ${T}_{c}$=89.5 K for the midpoint of the resistive transitions, and (${\mathrm{dB}}_{c2}$/dT${)}_{T={T}_{c}}$=5\ifmmode\pm\else\textpm\fi{}1 T/K and ${T}_{c}$=95.1 K for the onset. The estimates for ${B}_{c2}$(0) range from 80 to 320 T. Pulsed-field data suggest that a fraction of the material is still superconducting above 45 T at 77 K.
Multireceptor fingerprints in progressive supranuclear palsy (2017)

We demonstrate, for the first time to our knowledge, that kainate and A<sub>1</sub> receptors are altered in PSP and that clinically identifiable PSP subgroups differ at the neurochemical level. Numerous receptors were altered in the midcingulate cortex, further suggesting that it may prove to be a key region in PSP. Finally, we add to the evidence that nondopaminergic systems play a role in the pathophysiology of PSP, thus highlighting potential novel treatment strategies.
Novel Filter for Biological Materials (1964)

Thin plastic sieves with precisely controlled hole size and density can be made by irradiating plastic films with fission fragments and etching out the material traversed by the fragments. These filters may be used for the nondestructive separation of cells of closely similar sizes.
Magnesium recycling by |J carbonation and centrifugation of high-lime wastewater sludge (2016)

High-lime treatment of secondary effluent or of raw wastewater is a common process in wastewater reuse schemes, as well as in advanced wastewater treatment plants, which must comply with stringent discharge re quirements. The high-lime process usually fulfills a va riety of functions: clarification by coagulation-sedimen tation of suspended matter (including algae); phospho rus precipitation; removal of dissolved organics, color, heavy metals, and trace elements; disinfection by re moval and inactivation of bacteria and viruses; soften ing; and preparation for nitrogen removal by ammonia stripping.
Interaction, imagination and immersion some research needs (2000)

This paper discusses four ways that humans interact with their environments, plus four variables that determine the experience of virtual reality, and also which of the interactions support which of the VR-enhancing variables. Some philosophical issues abou immersion, the experience of presence, and the meaning of realit are then considered. The engineering paradigm of estimation is then reviewed as a way of bridging classical ontologica differences of opinion about reaility. Finally some VR research needs are discussed: haptics, mi nimally invasive diagnosis and surgery, driving simulation, decision aids in system operation, education, computer-aided synthesis, measures of presence and whether presence enhances performance, social ills of VR, and the relation of VR to spirituality.

Exploring the design space of composite visualization (2012)

We propose the notion of composite visualization views (CVVs) as a theoretical model that unifies the existing coordinated multiple views (CMV) paradigm with other strategies for combining visual representations in the same geometrical space. We identify five such strategies - called CVV design patterns - based on an extensive review of the literature in composite visualization. We go on to show how these design patterns can all be expressed in terms of a design space describing the correlation between two visualizations in terms of spatial mapping as well as the data relationships between items in the visualizations. We also discuss how to use this design space to suggest potential directions for future research.

Breeding and cultivation of industrial hemp in Poland (2009)

In recent years we are witnesses of the growth of interest in agriculture, industry and environmental movements in reproducible plant materials, including fibrous hemp – a plant attractive both to the agriculture and many industries. In addition to traditional textile use, the use of hemp found, inter alia, in the paper industry, construction materials, automotive, energy, cosmetics, pharmaceutical and chemical industries. Also in Poland, after the crisis, the growth of interest in hemp is demonstrated by the increase in area from 100 ha in 2003 to more than 1,600 ha in 2008. In Poland, work with hemp breeding started in 1946. At that time, the content of crude fiber in straw was only 14.3%. As a result of the multi-breeding work out this contents grew to 25–30%. The first the Polish monoecious hemp variety, entered in 1968 in the Register of Varieties is Bialobrzeskie. This variety of high economic value has successfully grown to this days not only in Poland, but also in the European Union. At present, in the National Register of COBORU there are five varieties of monoecious hemp grown in INF&MP: Bialobrzeskie, Beniko, Silesia, Tygra and Wielkopolskie. These are varieties adapted to Polish climate and soil conditions. When applied for proper growing conditions, they ensure high and stable yields. In accordance with the requirements of the Drugs Act of 29 July 2005, which regulates the cultivation of hemp in Poland, all Polish varieties and breeding prospective families contain less than 0.2% of hallucinogens. Growing hemp does not require, as a rule, use of plant chemical protection, provides high yields, leaving the soil in a very good structure. The new varieties, technologies and cultivation of cannabis harvest to total mechanization and obtain the raw material for specific technological parameters, caused the hemp plant has become attractive for both agriculture and industry.
Allergic Fungal Sinusitis/Polyposis (1996)

In the last decade, the medical community has recognized allergic fungal sinusitis as an unique clinical entity strongly associated with nasal polyps. We will review the differential diagnosis, clinical features, diagnosis, treatment, and prognosis. Appropriate management requires distinguishing allergic fungal sinusitis from other forms of chronic fungal and bacterial sinusitis. Surgical treatment initially results in dramatic improvement, and oral steroids help maintain postoperative success. However, recurrent disease eventually prevails, leaving a glaring need for improved medical treatment.
Empirical studies of competitve spinning for a shared-memory multiprocessor (1991)

A common operation in multiprocessor programs is acquiring a lock to protect access to shared data. Typically, the requesting thread is blocked if the lock it needs is held by another thread. The cost of blocking one thread and activating another can be a substantial part of program execution time. Alternatively, the thread could spin until the lock is free, or spin for a while and then block. This may avoid context-switch overhead, but processor cycles may be wasted in unproductive spinning. This paper studies seven strategies for determining whether and how long to spin before blocking. Of particular interest are competitive strategies, for which the performance can be shown to be no worse than some constant factor times an optimal off-line strategy. The performance of five competitive strategies is compared with that of always blocking, always spinning, or using the optimal off-line algorithm. Measurements of lock-waiting time distributions for five parallel programs were used to compare the cost of synchronization under all the strategies. Additional measurements of elapsed time for some of the programs and strategies allowed assessment of the impact of synchronization strategy on overall program performance. Both types of measurements indicate that the standard blocking strategy performs poorly compared to mixed strategies. Among the mixed strategies studied, adaptive algorithms perform better than non-adaptive ones.

Cellulose Acetate Polymer Thrombosis for the Emergency Treatment of Aneurysms (1994)

Cellulose acetate polymer solution is a liquid thrombotic material that hardens into the shape of an aneurysm into which it is injected. Therapy using this solution is a rapid technique that helps prevent the rupture of aneurysms, especially those that extravasate contrast material during angiography in the acute stage of subarachnoid hemorrhage. Using this polymer solution and an endovascular technique, we treated two patients who had aneurysms of the basilar and anterior communicating arteries with extravasation of contrast material during angiography a few hours after the initial subarachnoid hemorrhage. In one patient with an aneurysm of the anterior communicating artery, the aneurysm's wall was perforated with the catheter during neurointerventional procedures. In both patients, postoperative angiograms demonstrated obliteration of the aneurysmal dome, including the site of extravasation or perforation. The parent artery and surrounding perforating branches were preserved. Although we do not advocate aggressive therapy for patients who bleed during angiography, we pursued this therapy in these two patients because of the opportunity to introduce cellulose acetate polymer in an attempt to preserve the patients' lives. Unfortunately, both patients died. Histopathological studies performed at the time of autopsy demonstrated that the luminal surface of cellulose acetate polymer was covered with thrombus by 6 days after cellulose acetate polymer thrombosis. By 10 days, the thrombus had a prominent fibrin network, a concentrated plasma component, and few fibrocytes adhering to its luminal surface.(ABSTRACT TRUNCATED AT 250 WORDS)
