Calculation of Small Antennas Quality Factor Using FDTD Method (2006)

The complexity in the evaluation of the radiation quality factor Q of small antenna lies in the calculation of the stored energy. Previous authors proposed several analytical expressions for simple antennas to obtain the Q, which is of practical importance because of its relationship to the antenna bandwidth. This letter presents a general numerical method to calculate the Q using finite-difference time-domain (FDTD) method giving us accurate results and can be applied to complex antennas. Examples of a linear dipole antenna, a loop antenna and an inverted L-shaped antenna along with their results are presented and compared to analytical results of the literature.
[Significance of lactate dehydrogenase measurements in diagnosis of malignancies]. (2004)

The clinical stage of cancer is the end result in a complex, multistage carcinogenic process, during which several regulatory circuits are altered. These alterations often manifest themselves through changes in the cellular enzymatic patterns. It is well known that the most prominent biochemical feature of malignant cells remains the high glycolytic activity, the result of which is production of a large quantity of lactic acid. Lactic acid dehydrogenase (LDH) is considered a key enzyme in glycolysis. It catalyses the process of lactate production in pirogronian reduction reaction. Five active isoenzymes of LDH can be found in human tissues. Each isoenzyme is a tetrametric composition of two subunits, A(M) and B(H), encoded by separate genes (Ldh-A and Ldh-B respectively). Each subunit determines metabolic characteristics of isoenzymes and predisposes them to activity either in aerobic (B-type isoenzymes) or anaerobic environment (A-type isoenzymes). Therefore each normal tissue has its own special LDH activity pattern, depending on its function. In malignant tumours the macromolecular synthesis is changed in favour of subunit A in comparison with the healthy tissues from which they derive. It results in a dominance of the cathodic isoenzymes, which move slowest after electrophoresis, namely LD5 and LD4. It is even thought that izoenzymograms of most malignant tumours do not differ. Similar changes in isoenzyme activity of LDH are observed in morphologically normal tissues, adjacent to the tumour, which can suggest early pre-tumour stage in those tissues. In this report we summarise basic physico-chemical properties of LDH and discuss its clinical significance in diagnosis and prognosis of neoplastic diseases.

Single-waveguide power-combined multipliers for next generation LO sources above 100 GHz (2010)

The next generation of local oscillator terahertz sources will demand novel and efficient power-combined frequency multiplier structures able to handle the increasing available power provided by state-of-the-art solid-state sources and amplifiers at W-band. In this paper, we give a brief overview of the different proposed alternatives and describe a new concept of frequency multiplier featuring two GaAs Schottky diode based MMIC chips on a single wave-guide structure. This scheme adds an extra symmetry to the multiplier circuit with respect to previously reported power-combined structures, increasing the power handling capabilities of frequency multipliers by an additional factor of two. GaAs foundry, post-processing, waveguide block micromachining and testing will be fully performed within the European Union.
Management of Factor VIII Inhibitors: Evolution and Current Status (1992)

Management of patients with factor VIII (and IX) inhibitors includes management of acute bleeds and methods to induce immune suppression and tolerance and to detect patients at risk of developing inhibitors. The methods used over the years to treat acute bleeding have been more or less successful. The best method is to raise factor VIII levels by human or porcine factor VIII concentrate, but this is not usually possible. Prothrombin complex concentrates, activated or non-activated, have enjoyed some success as factor VIII by passing agents, but the development of recombinant activated factor VII represents a new and promising method of inducing haemoslasis at the site of bleeding whilst minimizing the risk of disseminated intravascular coagulation. Alternatively, the use of tissue factor is under consideration to exploit the extrinsic system. Methods to induce immunological tolerance by use of the 'Bonn' regime or by the introduction of immunomodulation with the 'Malmö' regime of extracorporeal immunodepletion, cyclophosphamide, and intravenous immunoglobulin continue to be attempted with significant but variable success. Gradually the inhibitor problem is being contained, but it is still an important complication of haemophilia therapy.
A generalized method for maintaining views (1984)

A generalized method for maintaining views, which takes into account each view's pattern of usage, is described. This method involves storing views in both actual and potential forms. When views exist in actual form (concrete views), updates are deferred until the view is queried. Differential files are formed from tuples inserted and deleted from the defining relations. These differential files are then used in conjunction with specified update schemes to update the view. Views alternate between actual and potential form based on their usage and the storage replacement algorithm.
Beyond Word Importance: Contextual Decomposition to Extract Interactions from LSTMs (2018)

The driving force behind the recent success of LSTMs has been their ability to learn complex and non-linear relationships. Consequently, our inability to describe these relationships has led to LSTMs being characterized as black boxes. To this end, we introduce contextual decomposition (CD), an interpretation algorithm for analysing individual predictions made by standard LSTMs, without any changes to the underlying model. By decomposing the output of a LSTM, CD captures the contributions of combinations of words or variables to the final prediction of an LSTM. On the task of sentiment analysis with the Yelp and SST data sets, we show that CD is able to reliably identify words and phrases of contrasting sentiment, and how they are combined to yield the LSTM's final prediction. Using the phrase-level labels in SST, we also demonstrate that CD is able to successfully extract positive and negative negations from an LSTM, something which has not previously been done.
Privacy-Preserving Aggregate Queries for Optimal Location Selection (2017)

Today, vast amounts of location data are collected by various service providers. These location data owners have a good idea of where their users are most of the time. Other businesses also want to use this information for location analytics, such as finding the optimal location for a new branch. However, location data owners cannot share their data with other businesses, mainly due to privacy and legal concerns. In this paper, we propose privacy-preserving solutions in which location-based queries can be answered by data owners without sharing their data with other businesses and without accessing sensitive information such as the customer list of the businesses that send the query. We utilize a partially homomorphic cryptosystem as the building block of the proposed protocols. We prove the security of the protocols in semi-honest threat model. We also explain how to achieve differential privacy in the proposed protocols and discuss its impact on utility. We evaluate the performance of the protocols with real and synthetic datasets and show that the proposed solutions are highly practical. The proposed solutions will facilitate an effective sharing of sensitive data between entities and joint analytics in a wide range of applications without violating their customers' privacy.
Direct nanoscale observations of the coupled dissolution of calcite and dolomite and the precipitation of gypsum (2014)

In-situ atomic force microscopy (AFM) experiments were performed to study the overall process of dissolution of common carbonate minerals (calcite and dolomite) and precipitation of gypsum in Na2SO4 and CaSO4 solutions with pH values ranging from 2 to 6 at room temperature (23 ± 1 °C). The dissolution of the carbonate minerals took place at the (104) cleavage surfaces in sulfate-rich solutions undersaturated with respect to gypsum, by the formation of characteristic rhombohedral-shaped etch pits. Rounding of the etch pit corners was observed as solutions approached close-to-equilibrium conditions with respect to calcite. The calculated dissolution rates of calcite at pH 4.8 and 5.6 agreed with the values reported in the literature. When using solutions previously equilibrated with respect to gypsum, gypsum precipitation coupled with calcite dissolution showed short gypsum nucleation induction times. The gypsum precipitate quickly coated the calcite surface, forming arrow-like forms parallel to the crystallographic orientations of the calcite etch pits. Gypsum precipitation coupled with dolomite dissolution was slower than that of calcite, indicating the dissolution rate to be the rate-controlling step. The resulting gypsum coating partially covered the surface during the experimental duration of a few hours.
Joint Processing Precoding for Coordinated Multi-Point Transmission in LTE-A (2010)

Coordinated Multi-Point (CoMP) transmission/reception is an efficient way to reduce inter-cell interference,improve the spectrum efficiency and coverage in LTE-A system,through Remote Radio Unit (RRU),base station or relay cooperation.Compared with other CoMP technologies,Joint Processing (JP),which carries out precoding based on channel information,can achieve the biggest system performance gain.Different precoding methods are suitable for different CoMP scenarios.Recently,more and more research concentrates on feedback compression and coded book optimization in CoMP precoding.
Elucidation of the structure of the antineoplastic agents, 2-formylpyridine and 1-formylisoquinoline thiosemicarbazones (1977)

The geometrical isomers of the antineoplastic agents 2-formylpyridine and 1-formylisoquinoline thiosemicarbazones were synthesized and their structure was studied by spectroscopic methods. It was found that the compounds previously described in the literature and tested for carcinostatic activity were isomers with E configuration which probably contained minor amounts of Z isomers.

Shh Pathway Activity Is Down-Regulated in Cultured Medulloblastoma Cells: Implications for Preclinical Studies (2006)

Gene expression profiling indicates that the Sonic Hedgehog (Shh) pathway is active in approximately 30% of human medulloblastomas, suggesting that it could provide a useful therapeutic target. Previously, we showed that spontaneous medulloblastomas in Ptc1(+/-)p53-/- mice could be eradicated by treatment with a small-molecule inhibitor (HhAntag) of Smoothened (Smo). Here, we compared the responses of mouse medulloblastoma cells propagated in flank allografts, either directly or after culture in vitro, to HhAntag. We found that Shh pathway activity was suppressed in medulloblastoma cells cultured in vitro and it was not restored when these cells were transplanted into the flank of nude mice. The growth of these transplanted tumor cells was not inhibited by treatment of mice with doses of HhAntag that completely suppressed Smo activity. Interestingly, tumor cells transplanted directly into the flank maintained Smo activity and were sensitive to treatment with HhAntag. These findings indicate that propagation of tumor cells in culture inhibits Smo activity in a way that cannot be reversed by transplantation in vivo, and they raise concerns about the use of cultured tumor cells to test the efficacy of Shh pathway inhibitors as anticancer therapies.

Adjoint Operator Algorithms for Faster Learning in Dynamical Neural Networks (1989)

A methodology for faster supervised learning in dynamical nonlinear neural networks is presented. It exploits the concept of adjoint operators to enable computation of changes in the network's response due to perturbations in all system parameters, using the solution of a single set of appropriately constructed linear equations. The lower bound on speedup per learning iteration over conventional methods for calculating the neuromorphic energy gradient is O(N2), where N is the number of neurons in the network.

Water vapor absorption of carbon dioxide laser radiation (1976)

An optoacoustic detector or spectrophone has been used to perform detailed measurements of the absorptivity of mixtures of water vapor in air. A C(12) O(2)(16) laser was used as the source, and measurements were made. at forty-nine different wavelengths from 9.2 microm to 10.7 microm. The details of the optoacoustic detector and its calibration are presented, along with a discussion of its performance characteristics. The results of the measurements of water vapor absorption show that the continuum absorption in the wavelength range covered is 5-10% lower than previous measurements.
Acute Phase Protein, Serum Amyloid A, Inhibits IL‐1‐ and TNF‐Induced Fever and Hypothalamic PGE<sub>2</sub> in Mice (1991)

The effect of serum amyloid A (SAA) on fever induced by recombinant interleukin-1 beta (rIL-1 beta) or recombinant tumour necrosis factor alpha (rTNF alpha) was studied in mice. Serum amyloid A is an acute phase protein whose rise in pathological events is induced by the cytokines IL-1, IL-6 and TNF. Administration of human serum amyloid A to mice inhibited fever induced by rIL-1 beta or rTNF alpha in vivo, while the addition of human serum amyloid A to mice hypothalamic slices inhibited IL-1 beta- or TNF alpha-induced prostaglandin E2 (PGE2) production in vitro. Since serum amyloid A did not affect body temperature or hypothalamic PGE2 levels when administered alone, it may represent a specific servo-mechanism for fever regulation in acute events, and it suggests, for the first time, a possible feedback relationship between serum amyloid A and the immunoregulatory cytokines.

Stereoselective [4 + 1] Annulation Reactions with Silyl Vinylketenes Derived from Fischer Carbene Complexes (2006)

Stable silyl vinylketenes were prepared via the thermal reaction of Fischer carbene complexes with triisopropylsilyl- or tert-butyldimethylsilyl-substituted alkynes. The ability of these silyl vinylketenes to participate with carbenoid reagents in [4 + 1] annulation reactions was investigated. The best results were obtained with diazomethane and substituted diazomethane reagents, which provided cyclopentenone products in excellent yields and essentially complete stereoselectivity.
Cervical cancer control, priorities and new directions (2003)

Cervical cancer is caused by infection with a range of high risk "oncogenic" human papillomavirus (HPV) types, and it is now accepted that >99% of cervical cancer is initiated by HPV infection. The estimated lifetime risk of cervical cancer is nevertheless relatively low (less than 1 in 20 for most community based studies). Although sensitivity and specificity of the available diagnostic techniques are suboptimal, screening for persistent HPV infection is effective in reducing the incidence of cervical cancer. Infection can be detected by molecular techniques or by cytological examination of exfoliated cervical cells. Persistent infection is the single best predictor of risk of cervical cancer. The latest findings of HPV and cervical cancer research need to be widely disseminated to the scientific and medical societies that are updating screening and management protocols, public health professionals, and to women and clinicians. This report reviews current evidence, clinical implications and directions for further research in the prevention, control and management of cervical cancer. We report the conclusions of the Experts' Meeting at the EUROGIN 2003 conference.
A 10 Gb/s Inductorless AGC Amplifier With 40 dB Linear Variable Gain Control in 0.13 $\upmu \text{m}$ CMOS (2015)

This work presents an inductorless, 10 Gbps automatic gain control (AGC) circuit including a speed enhanced variable gain amplifier (VGA), a power detector, a comparator, and a novel exponential function generator for extended dBlinear performance. Third-order interleaved feedback technique is utilized in the current steering VGA stage to achieve 10 Gb/s operation without using on-chip inductors. A stagger-tuned switching architecture for CMOS exponential function generation is proposed to achieve a dB-linear gain control range of ~40 dB with better than ±1 dB gain error. The relationship between tuning range and approximation error is analyzed and a novel current ratio generator circuit is proposed to implement the approximation functions in the current domain. The AGC circuit achieves a highest data rate of 10 Gb/s for 231-1 PRBS input, maintaining 360 mVp-p constant differential output with a BER <;10-12 for an input dynamic range of ~24 dB (15-240 mVp-p). Fabricated in IBM 0.13 μm CMOS technology, the chip draws 50 mW from a 1.2 V power supply (excluding the output buffer) and occupies an active area of 0.4 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
