An ultrahigh vacuum tip transfer system for the scanning tunneling microscopy/field ion microscopy (1990)

The authors have developed a magnet-type tip transfer system for use in an ultrahigh vacuum scanning tunneling microscopy/field ion microscopy (UHV-STM/FIM) system. The construction of the tip transfer system ensures that a tip can be introduced into the STM and the FIM in situ without any chances of tip crushing during handling. The new tip transfer system is extremely simple and reliable, and is particularly suitable for rapid tip exchange in the STM. An atom-resolved image of a highly oriented pyrolytic graphite has been obtained with a tungsten tip characterized by an FIM and transferred to an STM via this transfer system.
Novel approaches to optical reflectometry (2002)

The author reviews the fundamentals of optical reflectometry, including the standard optical time-domain reflectometry (OTDR) measurement. Some novel reflectometry schemes are described, including a spread-spectrum approach to long-range OTDR, as well as new optical frequency-domain reflectometry (OFDR) techniques that have proven useful for high-resolution measurements. These novel reflectometry techniques are suitable for testing both fiber links and small components. The spread-spectrum technique allows improved dynamic range without sacrificing resolution. High-speed modulators and detectors now allow the extension of OFDR techniques to high frequencies. Resulting measurements show a large dynamic range and resolution better than 4 mm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Role of GABA in anxiety and depression (2006)

This review assesses the parallel data on the role of gamma-aminobutyric acid (GABA) in depression and anxiety. We review historical and new data from both animal and human experimentation which have helped define the key role for this transmitter in both these mental pathologies. By exploring the overlap in these conditions in terms of GABAergic neurochemistry, neurogenetics, brain circuitry, and pharmacology, we develop a theory that the two conditions are intrinsically interrelated. The role of GABAergic agents in demonstrating this interrelationship and in pointing the way to future research is discussed.

Characterization of two highly metastatic variants of Lewis lung carcinoma with different organ specificities. (1986)

The biological properties and metastasis of two sublines of the Lewis lung carcinoma (3LL) which have maintained a stable pattern of organ-selective metastasis have been studied. Subline M-3LL, a lung-specific variant which originated from a lung metastasis of the parent line, metastasized only to the lung following injection of 10(4)-10(6) tumor cells i.v. or s.c. Lymphatic metastases of this tumor were rarely detected. Subline H-3LL which was developed from a rare, spontaneous hepatic metastasis of the parent line metastasized primarily to the liver, but pulmonary metastases have also been observed. While it grew at local s.c. sites, this tumor metastasized to the regional lymph nodes draining the tumor site, as determined by histology and by bioassay of the lymph nodes following their grafting into new recipient animals. Histologically, the two lines were indistinguishable with the exception of a higher incidence of giant cells detected in tissue sections and culture monolayers of the liver-colonizing variant H-3LL. Ten clones derived from each of the variant lines were expanded in vitro and inoculated i.v. While none of the ten clones derived from line M-3LL gave rise to extrapulmonary metastasis, nine of ten clones derived from Tumor H-3LL gave rise to hepatic metastasis. Highly metastatic clones selected from each tumor were subsequently used to study the patterns of distribution and arrest of radiolabeled tumor cells following their inoculation i.v. No correlation could be found between the initial distribution of the radiolabeled tumor cells and the organ selectivity eventually noted in the site of the metastases.

A High-Throughput Screening Assay for NKCC1 Cotransporter Using Nonradioactive Rubidium Flux Technology (2017)

A high-throughput screening (HTS) assay was developed for cotransporter, NKCC1, which is a potential target for the treatment of diverse disorders. This nonradioactive rubidium flux assay coupled with ion channel reader series provides a working screen for this target expressed in human embryonic kidney (HEK) cell line. An eightfold window of detection was achieved with the optimized assay. This new functional assay offered a robust working model for NKCC1 in determining reliable and concordant rank orders of the test compounds supporting its sensitivity and specificity. The robustness of manual assay indicated by Z' of 0.9 qualified its amenability to automation. The Z' of 0.7 was displayed by automated assay employed in high-throughput screening of compound libraries against this target. Being electrically neutral, the NKCC1 screening is difficult to achieve by both manual and automated electrophysiological techniques. These techniques, although considered gold standard, suffer from their inherent problems of being too slow to be in high-throughput format and with high running costs. In addition to being a functional assay for NKCC1, it is nontoxic as compared with thallium flux assay, which is prone to generate high number of false-positive/false-negative rates because of its innate fluorescence issues.
Effects of dissolved hydrogen on durability of silica glass under excimer laser irradiation. (1991)

As an evaluation of durability of synthetic silica glass under irradiation of KrF excimer laser (5.0 eV) or ArF excimer laser (6.4 eV), degradation of transmission was studied for a sample that contained 4×1018 molecules/cm3 H2 but was substantially free of other impurities. First, Khotimchenko’s method of H2 analysis was examined with specimens whose H2 contents were varied by vacuum degassing, covering three orders of magnitude down to H2-free (i.e., less than the instrumental detection limit of 5×1016). It was shown that this method was quite reliable.Then the effects of dissolved H2 were assessed. The hydrogen molecules were decomposed under excimer laser irradiation, and reacted with the E’ center. For KrF excimer laser irradiation, the degradation of transmission was found to be suppressed, when the concentration of hydrogen much increased. Whereas for ArF excimer laser irradiation, there seemed to exist an optimum concentration range.The author proposes a reaction model for the last observation as:≡ Si–O–Si ≡+ H2+hν→≡Si·+·O–Si≡+ H2→≡+Si–H + H–O–Si ≡, where ≡Si· is the E’ center, and ·O–Si≡ , the non-bxsridging oxygen hole center.

Studies on urinary thrombomodulin in toxemia of pregnancy. (1989)

Thrombomodulin (TM) is known to exist in the glomerulus and to be excreted in urine. To elucidate biochemical properties of urinary TM in normal and toxemic pregnancy, the levels of immunoreactive TM (TM antigen) and its activities were measured by ELISA and by a protein C activation method, respectively. The samples for measurements were prapered from urine by DIP-thrombin agarose affinity chromatography.The urinary protein fraction bound to DIP-thrombin agarose, obtained from normal pregnants, pregnants with early onsets type toxemia (24-28 weeks of gestation), and with late onset type toxemia (later than 32 weeks) commonly showed a single band with a mol. wt. 63Kd in SDS-polyacrylamide gel electrophoresis with silver staining.The levels of urinary TM antigen and TM activity in normal pregnancy increased with gestation weeks. Those in late onset type pregnancy showed similar chnges. There was no difference in the ratio of TM activity/antigen between these two types of pregnancy. However, in early onset type toxemia the level of TM activity was low, and, further, the ratio of TM activity/antigen was extremely low.The TM in early onset type toxemia had a significantly lower Vmax than that in normal pregnancy. These findings suggested that the TM in early onset type toxemia was functionally impaired as a cofactor for thrombin.
Effect of heat-killed <i>Streptococcus thermophilus</i> on type 2 diabetes rats (2019)

Our study supports the hypothesis that treatment with heat-killed <i>S. thermophilus</i> could effectively improve glycemic parameters in T2D model rats. In addition, the potential mechanisms underlying the protection maybe include changing the composition of gut microbiota, reinforcing the intestinal epithelial barrier and the immunity of the intestinal mucosa, decreasing the level of inflammation, and then reducing the insulin resistance.
Polyphase implementation of a video scalar (2002)

Image scaling is important in the conversion between different formats such as NTSC, PAL, HDTV and between the CCIR 601 video resolution to the various sizes included in MPEG coding. The change of the resolution proves specially beneficial for improving the coding efficiency. The scaling operation can be generalized by decimation by a factor of M followed by filtering and then interpolation by a factor of L where M and L are integers. The choice of the digital filter depends on the values of L and M. For certain resolution changes, M and L can be rather large integers. Conventional implementation of the filter may result in huge memory and computational requirements. To reduce this factor for practical applications, a polyphase implementation of the digital filter for the video scalar is presented. Some factors determining the choice of the digital filter are discussed. Finally, examples are shown for different resolution scaling of an image.

Leucoderma treated by transplantation of a basal cell layer enriched suspension (1998)

The aim of this study was to test the usefulness of a melanocyte-enriched cell suspension for the treatment of leucoderma. After removal of a superficial (4-30 cm2) skin sample, the cells were mechanically separated in a trypsin-EDTA solution, centrifuged and washed in a melanocyte medium. The melanocyte-enriched epidermal cell suspension devoid of stratum corneum and stratum granulosum was then applied to the dermabraded depigmented skin. The 26 patients treated had piebaldism (three), vitiligo vulgaris (17), segmental vitiligo (three), halo naevi (one), naevus depigmentosus (one) and chemical leucoderma (one). In patients with widespread piebaldism we found that by diluting the cell suspension the recipient area could be increased to up to 10 times the size of the donor area with the same good results as without or with less dilution. In patients with vitiligo areas of between 50 and 90 cm2, the recipient areas were increased three- to fivefold in the donor area. Patients with piebaldism, segmental vitiligo and halo naevi healed completely, as did most patients with vitiligo. In naevus depigmentosus no effect was seen. Our new method for treatment of leucoderma has the advantage that cell culture is not needed and that it is more suitable than epidermal sheet grafts when several small areas are to be treated.
Maternal and larval effects of photoperiod on the induction of larval diapause in two species of fly, Calliphora vicina and Lucilia sericata. (1986)

The induction of larval diapause in the blowflies Calliphora vicina and Lucilia sericata was studied in relation to maternal and/or larval exposure to photoperiod. In C. vicina, maternal experience of short daylength was shown to be more important than larval exposure, although diapause was only observed when the larval rearing temperature was below 15 degrees C. The critical daylength was between 12 and 15 h per day. Recovery from diapause was temperature- but not photoperiod-dependent. Some evidence was obtained, however, to suggest that the rate of recovery was more rapid among larvae from short-day mothers which were bred in pre-diapause conditions of long days. By transferring adult flies from short days into darkness several days before oviposition, it was shown that the important photoperiodic effects were truly maternal. In L. sericata, larval sensitivity to photoperiod was also demonstrated, short days inducing a protracted rate of pupariation. 'Waves' of pupariation in short-day cultures indicated intrinsic differences in diapause intensity. The critical day-length for larval sensitivity was close to 14 h per day. It is suggested that the maternal effects of photoperiod on larval diapause probably involve an unknown maternal factor which is incorporated into the developing oocytes during short-day exposure.
Mercury-arc valves for high-voltage d.c. transmission (1964)

Use of the high-voltage direct-current method for power transmission necessitates conversion of a.c. into h.v.d.c. for the line, and conversion of the d.c. back to a.c. again. The critical component of such convertors is the controllable electric valve. The basic problem of extending the voltage range of mercury-arc valves to these high levels is outlined, as well as the nature of the underlying development work. Some features of present-day valves are quoted, as well as some considerations which have to be taken into account when designing the convertor circuits, owing to the properties and limitations of actual valves.
Making the circular self-test path technique effective for real circuits (1994)

The paper assesses the effectiveness of the circular self-test path BIST technique from an experimental point of view and proposes an algorithm to overcome the low fault coverage that often arises when real circuits are examined. Several fault simulation experiments have been performed on the ISCAS89 benchmark set, as well as on a set of industrial circuits: in contrast to the theoretical analysis proposed in [PKKa92], a very high fault coverage is attained with a limited number of clock cycles, but this happens only when the circuit does not enter a loop. This danger cannot be avoided even if clever strategies for flip-flops ordering, aimed at reducing the functional adjacency, are adopted. Instead, we suggest that loops can be avoided and fault coverage increased by carefully choosing the initial state, and we present an approach based on binary decision diagrams and symbolic techniques to solve the problem.
Tetranuclear Mixed-Metal M<sup>II</sup><sub>2</sub>Cu<sup>II</sup><sub>2</sub> Complexes Derived from a Phenol-Based Macrocyclic Ligand Having Two N(amine)<sub>2</sub>O<sub>2</sub> and Two N(imine)<sub>2</sub>O<sub>2</sub> Metal-Binding Sites (2001)

The reaction of N,N'-dimethyl-N,N'-ethylenebis(5-bromo-3-formyl-2-hydroxybenzylaminato)copper(II) with ethylenediamine in aqueous DMF with excess perchloric acid resulted in the [2:2] cyclic condensation of the constituents, providing the dinuclear Cu(II) complex [Cu2(H2R)](ClO4)2. It crystallizes in the monoclinic space group P2(1)/c, with a = 19.603(3) A, b = 13.370(2) A, c = 21.072(3) A, beta = 98.87(1) degrees, V = 5456(1) A3, and Z = 4. The ligand R4- has two N(amine)2O2 and two N(imine)2O2 metal-binding sites sharing two phenolic oxygens, and [Cu2(H2R)](ClO4)2 has the two Cu(II) ions in the N(imine)2O2 sites and two protons in the N(amine)2O2 sites. [Cu2(H2R)](ClO4)2 was converted by neutralization into [Cu2(R)], from which mixed-metal Cu(II)2M(II)2 complexes [Cu2M2(R)Cl4] (M = Co(II), Ni(II), Zn(II)) were derived. [Cu2Co2(R)Cl4]*2CHCl3*H2O crystallizes in the monoclinic space group C2/c, with a = 32.514(3) A, b = 12.246(3) A, c = 19.827(2) A, beta = 126.082(1) degrees, V = 6380(1) A3, and Z = 4. [Cu2Zn2(R)Cl4]*2CHCl3*H2O crystallizes in the monoclinic space group C2/c, with a = 32.53(1) A, b = 12.242(2) A, c = 19.729(9) A, beta = 126.03(3) degrees, V = 6354(4) A3, and Z = 4. The two complexes are isotructural and have a dimer-of-dimers structure with two separated Cu(II)M(II) units. In each dinuclear unit, the Cu(II) is bound to the N(imine)2O2 site and the M(II) is bonded to a phenolic oxygen and two nitrogens of the N(amine)2O2 site. The Cu(II) and M(II) ions are bridged by a phenolic oxygen and an exogenous chloride ion. The Cu(II)2Ni(II)2 complex has a defect double-cubane structure. Cryomagnetic studies for the Cu(II)2Co(II)2 complex indicate an antiferromagnetic spin-exchange interaction within each dinuclear Cu(II)Co(II) unit (J = -9.5 cm(-1) based on H = -2JS(Cu)S(Co)). The Cu(II)2Ni(II)2 complex shows a weak antiferromagnetic interaction between the adjacent Cu(II) and Ni(II) ions (-3.5 cm(-1)) and a weak ferromagnetic interaction between the two Ni(II) ions (+2.0 cm(-1)).

Scheduling tasks with precedence constraints to solicit desirable bid combinations (2003)

In our previous research we suggested an approach to maximizing agents preferences over schedules of multiple tasks with temporal and precedence constraints. The proposed approach is based on Expected Utility Theory. In this paper we address two mutually dependent questions: (a) what are the properties of the problem domain that can facilitate efficient maximization algorithms, and (b) what criteria determine attractiveness of one or another potential solution to the agent. We discuss different ways of exploring the problem domain. We show that naive optimization approaches often fail to find solutions for risk-averse agents and propose ways of using properties of the domain to improve upon naive approaches.
