Rigorous Characterization of Resonant Hot Spot Conditions in a Stratified Tissue Model (2007)

A unified approach for determining the lossy resonance (hot-spot) conditions in a lossy stratified biological tissue model is proposed. These conditions may lead to a significant enhancement of local electromagnetic power deposition in a single layer as compared to the power dissipated in the background. Rigorous analysis of electromagnetic wave power absorption in a planar stratified tissue model renders a closed-form characterization of six possible asymptotic cases and the associated conditions and bounds on the optimal absorption in the particular layer as a function of its normalized thickness and parameters of the surrounding layers. It is shown that, even very thin and low attenuating layers (sites) of biological tissue, are capable of dissipating a very substantial amount of the incident power, subject to specific lossy resonance conditions. From a dosimetric point of view, the results obtained allow for prediction of naturally occurring spatial resonances in biological tissues on both macroscopic and microscopic scales. On the other hand, they also provide an effective mean for design and synthesis of optimally absorbing materials and tissues in therapeutic applications
Mixed amide thiolate complexes of zinc with low coordination number at the metal atom (1992)

Abstract Three different thiophenoles 2,4,6‐(CF 3 ) 3 C 6 H 2 SH ( 4 ), 2,4,6‐( i Pr) 3 C 6 H 2 SH ( 5 ), and 2,6‐(Me 3 Si) 2 C 6 H 3 SH ( 6 ) with bulky sub‐stituents in ortho position were treated with Zn[N(SiMe 3 ) 2 ] 2 ( 7 ) in a non‐coordinating solvent like CH 2 Cl 2 or toluene to yield mixed amide thiolate zinc complexes Zn 2 [N(SiMe 3 ) 2 ]{S[2,4,6‐(CF) 3 C 6 H 2 ]} 3 ( 8 ), Zn 3 [N(SiMe 3 ) 2 ] 2 {S[2,4,6‐( i Pr) 3 C 6 H 2 ]} 4 ( 9 ), and Zn 2 {S[2,6‐(Me 3 Si) 2 C 6 H 3 ]} 4 ( 10 ), respectively. These compounds comprise low‐coordinated zinc atoms. Initially, the reactions were performed in a 1:1 ratio of the reactants. However, in no reaction the expected {Zn[N(SiMe 3 ) 2 ](SR)} x (X = 1,2,3…) species were obtained but compounds which are richer in thiolate substituents (SR/NR 2 &gt; 1) even if a large excess of amide 7 was used. Distinct from these, the reaction between 7 and 2,6‐( i Pr) 2 C 6 H 3 OH ( 14 ) in a 1:1 ratio afforded indeed dimer Zn 2 [N(SiMe 3 ) 2 ] 2 {O[2,6‐( i Pr) 2 C 6 H 3 ]} 2 ( 15 ). The molecular structures of 8, 9, 10 , and 15 in the crystal are elucidated by X‐ray structural analyses and compared with proposed structures in solution based on multinuclear NMR experiments.

Extending the Scope of a Known Furan Synthesis - A Novel Route to 1,2,4-Trisubstituted Pyrroles (2002)

2-(Acylmethylene)propanediol diacetates, which cyclize readily under acidic conditions to give furans (76-84%) react with primary amines under palladium catalysis to give 1,2,4-trisubstituted pyrroles in moderate to good yields (39-53%). When glycine methyl ester is used as the amine, substituted methyl pyrrol-1-ylacetates (31-82%) are obtained.
Change in capsulorhexis size after implantation of three types of intraocular lenses (1997)

The IOLs' haptic design seemed to play a major role in the evolution of the CCC. The CCC constriction seen with the Staar IOLs was related to their plate haptics.

Ursolic Acid-Based Derivatives as Potential Anti-Cancer Agents: An Update (2020)

Ursolic acid is a pharmacologically active pentacyclic triterpenoid derived from medicinal plants, fruit, and vegetables. The pharmacological activities of ursolic acid have been extensively studied over the past few years and various reports have revealed that ursolic acid has multiple biological activities, which include anti-inflammatory, antioxidant, anti-cancer, etc. In terms of cancer treatment, ursolic acid interacts with a number of molecular targets that play an essential role in many cell signaling pathways. It suppresses transformation, inhibits proliferation, and induces apoptosis of tumor cells. Although ursolic acid has many benefits, its therapeutic applications in clinical medicine are limited by its poor bioavailability and absorption. To overcome such disadvantages, researchers around the globe have designed and developed synthetic ursolic acid derivatives with enhanced therapeutic effects by structurally modifying the parent skeleton of ursolic acid. These structurally modified compounds display enhanced therapeutic effects when compared to ursolic acid. This present review summarizes various synthesized derivatives of ursolic acid with anti-cancer activity which were reported from 2015 to date.
<title>Content-based video browsing tools</title> (1995)

Browsing is important for multimedia content retrieval, editing, authoring and communications. Yet, we are still lacking browsing tools which are user friendly and content-based, at least for video materials. In this paper, we present a set of video browsing tools which utilize video content information resulting from a parsing process. Video parsing algorithms are briefly discussed and a detail description of both sequential and time-space browsing tools are presented.
Temperature dependence of coercivity in Co-based longitudinal thin-film recording media (1997)

The coercivity of Co-based (CoCrTa and CoCrPt), disk media was found to depend on temperature. The thinner the film, the smaller the switching unit (KuV), and the larger dHc/Hc dT. dHc/HcdT for CoCrTa (400 Å) on different underlayers or intermediate layers is generally larger than that of CoCrPt (400 Å) on different underlayers or intermediate layers. The temperature dependence of coercivity in Co-based disk media is caused by the temperature dependence of crystalline anisotropy of Co and small switching unit of the media.

Original Paper Electron Excited L X-Ray Spectra of the Elements 24 •Z •33 (2006)

A reinvestigation was undertaken in order to obtain reliable data of the relative intensities of the L spectra for the elements 24 � Z � 33. ATAP crystal with a periodicity of 25.757 A u was used as the dispersing element. With this crystal one is able to resolve the lines= bands Ll ¼ L3M1 ,L � ¼ L2M1 ,L � 1,2 ¼ L3M4,5 ,L � 1 ¼ L2M4 ,a nd L� 3,4 ¼ L1M2,3. Among the investigated ele- ments 33 As is the only one for which the energy of the lines L� 1,2 and L� 1 is below the L3 absorption edge. For all the other elements the lines Ll, L� ,a nd L� 1,2 are below the L3 edge, whereas L� 1 and L� 3,4 are above this edge. This difference leads to effects of differential absorption, where the absorption is stronger for decreas- ing line energy. For the net peak height ratio � 1=� we obtained results which are of the same order of magni- tude as those given by White and Johnson (W&J) in their popular tables. But for l=� and � 3,4=� 1 our results show an atomic number dependence which is complete- ly different from those given by W&J.
Polyadenylic Acid Sequences: Role in Conversion of Nuclear RNA into Messenger RNA (1971)

Polyadenylic acid [poly(A)] segments containing 150 to 250 nucleotides appear to be covalently linked to heterogeneous nuclear RNA (HnRNA) and messenger RNA (mRNA) in eucaryotic cells. The poly(A) is synthesized in the nucleus, and is probably linked initially to HnRNA that is ultimately transported as mRNA to the cytoplasm. Studies with inhibitors of RNA or poly(A) synthesis indicate that synthesis of poly(A) segments is independent of transcription. The poly(A) marker may prove useful to elucidate mRNA modification and transport in eucaryotic cells.s
Building Knowledge for AI Agents with Reinforcement Learning (2019)

Reinforcement learning allows autonomous agents to learn how to act in a stochastic, unknown environment, with which they can interact. Deep reinforcement learning, in particular, has achieved great success in well-defined application domains, such as Go or chess, in which an agent has to learn how to act and there is a clear success criterion. In this talk, I will focus on the potential role of reinforcement learning as a tool for building knowledge representations in AI agents whose goal is to perform continual learning. I will examine a key concept in reinforcement learning, the value function, and discuss its generalization to support various forms of predictive knowledge. I will also discuss the role of temporally extended actions, and their associated predictive models, in learning procedural knowledge. Finally, I will discuss the challenge of how to evaluate reinforcement learning agents whose goal is not just to control their environment, but also to build knowledge about their world.
Effect of Pretest Pressures and Temperature on DST Interpretation (1998)

Summary Drillstem tests (DST's) in porous media typically consist of a sequence of production and shut-in periods. Interpretations of DST's are often based on application of the Horner method to the shut-in periods. Such an analysis assumes that the wellbore rate is constant during the production period and that the pressure response during the shut-in is affected only by that production period. For many DST's, however, these assumptions are no longer valid and other interpretation methods are required. For example, prior production and shut-in periods and/or pretest pressures can significantly affect the pressure response of subsequent periods and cause erroneous parameter estimates. In this paper, we present a new DST semianalytical solution that can account for the effect of pretest pressures, prior test periods, wellbore temperature variations, and other factors such as wellbore storage and skin on the pressure response. The solution is an extension of the solution presented by Correa and Ramey1 who derived a DST solution by writing a single time-dependent wellbore boundary condition. Application of the new solution to example DST data shows that estimates of formation pressure from the Horner analysis can deviate from the true formation pressure by several hundred psia, whereas permeability estimates can differ by a factor of two or three.
Two-Dimensional near Infrared Spectroscopic Imaging of the Hand to Assess Microvascular Abnormalities in Systemic Sclerosis: A Pilot Study (2015)

Patients affected by systemic sclerosis (SSc) develop functional and structural microvascular alterations and progressive fibrosis of the skin and internal organs. Evaluation of skin microcirculation is an important clinical step in the workup of SSc patients. Near infrared (NIR) spectroscopy is a well-established non-invasive technique to assess haemoglobin oxygen saturation (StO 2 ) in the illuminated tissue. The recent development of NIR spectroscopic two-dimensional (2D) imaging offers the possibility of visualising StO 2 distribution in large tissue areas. This is particularly important in SSc characterised by a very heterogeneous spatial distribution of the microvascular abnormalities. In addition, the short acquisition time of NIR spectroscopic images allows microvascular “dynamic” conditions, such as the vascular response to physical or pharmacological stimuli, to be evaluated. The present study reports the results of the test application of NIR spectroscopic 2D imaging of the palmar whole-hand surface for the evaluation of peripheral microcirculatory dysfunction in one patient with SSc, as compared with a healthy control, both in “static” (resting) and in “dynamic” (ischaemia-reperfusion) conditions. Spatial heterogeneity of microvascular alterations associated with temporal heterogeneity in vascular reactivity to ischaemic challenge make 2D NIR spectroscopic imaging a promising tool in the assessment of SSc, as compared with the current available techniques. A NIR spectroscopic camera by Kent Imaging Inc, Calgary, Canada was used.
Novel Pd(ii)–salen complexes showing high in vitro anti-proliferative effects against human hepatoma cancer by modulating specific regulatory genes (2012)

We have reported the synthesis of a novel salen ligand and its mononuclear Pd-salen complexes derived from 2-{[2-hydroxy-3-{[(E)-(2-hydroxyphenyl)methylidene]amino}propyl)imino]methyl}phenol. The newly synthesized and isolated Pd(II) complexes have been identified and fully characterized by various physico-chemical studies viz., elemental analyses, IR, UV-Vis, (1)H, (13)C NMR spectroscopy, electron spray ionization mass spectrometry (ESI-MS) and TGA/DTA studies. The molecular structure of the salen ligand has been ascertained by single-crystal XRD and it is coordinated to Pd(II) ion through two nitrogen and two oxygen atoms. The UV-Vis data clearly suggest a square-planar environment around both the Pd(II) ions. The DNA binding studies of the synthesized compounds has been investigated by electron spectroscopy and fluorescence measurements. The results suggest that Pd(II) complexes bind to DNA strongly as compared to the free ligand. The free salen ligand and its Pd(II) complexes have also been tested against human hepatoma cancer cell line (Huh7) and results manifested exceptional anti-proliferative effects of the Pd(II) complexes. The anti-proliferative activity of Pd(II) complexes has been modulated by specific regulatory genes.
Jerarquización de los valores en el personal operativo de transportes intervega S.A.C. del cercado de Lima, 2017 (2017)

The objective of the present investigation is to know the ranking of the values in the operative staff of the mass consumption company Transportes Intervega SAC of Cercado de Lima in the year 2017. The sample was formed by 75 male workers who occupy the position of drivers, liquidators and distributors, and whose ages fluctuate from the 18 to the 55 years of age. The instrument used for this research was the Portrait Values Questionnaire (PVQ), whose objective is to determine the hierarchy of values based on Schwartz's theory. With the results obtained it was concluded that the workers hierarchized the values of benevolence, security and self-direction, and as less selected values were tradition, achievement and power; confirming Schwartz's (1992) theoretical proposal on the two bipolar dimensions, where he stands as the first chosen value: benevolence (corresponding to the self- transcendence dimension) versus the last value chosen: power (corresponding to the self-enhancement dimension)
Data signal modulation based on uniform color space for digital signage and image sensor based visible light communication (2021)

This paper discusses a visible light communication (VLC) system using a digital signage and an image sensor. We propose a modulation scheme that data information signals are superimposed on a chroma component of the displayed image of the digital signage by taking advantage of the fact that human eyes are difficult to perceive chroma difference than brightness difference. Especially, the proposed scheme utilizes uniform color space to realize hardly perceivable data signal modulation. We show that the proposed scheme has better performance than the conventional scheme with the non-uniform color space.
Estimating the Helpfulness and Economic Impact of Product Reviews: Mining Text and Reviewer Characteristics (2010)

With the rapid growth of the Internet, the ability of users to create and publish content has created active electronic communities that provide a wealth of product information. However, the high volume of reviews that are typically published for a single product makes harder for individuals as well as manufacturers to locate the best reviews and understand the true underlying quality of a product. In this paper, we reexamine the impact of reviews on economic outcomes like product sales and see how different factors affect social outcomes such as their perceived usefulness. Our approach explores multiple aspects of review text, such as subjectivity levels, various measures of readability and extent of spelling errors to identify important text-based features. In addition, we also examine multiple reviewer-level features such as average usefulness of past reviews and the self-disclosed identity measures of reviewers that are displayed next to a review. Our econometric analysis reveals that the extent of subjectivity, informativeness, readability, and linguistic correctness in reviews matters in influencing sales and perceived usefulness. Reviews that have a mixture of objective, and highly subjective sentences are negatively associated with product sales, compared to reviews that tend to include only subjective or only objective information. However, such reviews are rated more informative (or helpful) by other users. By using Random Forest-based classifiers, we show that we can accurately predict the impact of reviews on sales and their perceived usefulness. We examine the relative importance of the three broad feature categories: “reviewer-related” features, “review subjectivity” features, and “review readability” features, and find that using any of the three feature sets results in a statistically equivalent performance as in the case of using all available features. This paper is the first study that integrates econometric, text mining, and predictive modeling techniques toward a more complete analysis of the information captured by user-generated online reviews in order to estimate their helpfulness and economic impact.
Coccidioidomycosis of the First Cuneiform: Successful Treatment Utilizing Local Debridement and Long-Term Ketoconazole Therapy (1986)

Although intravenous amphotericin B is generally considered to be the standard treatment for coccidioidomycosis, the treatment of monostotic coccidioidomycosis is controversial. Long-term intravenous and oral antifungal chemotherapy has been utilized alone and in conjunction with local surgical debridement. We present a case of coccidioidal osteomyelitis of a tarsal bone successfully treated with local surgical debridement and oral ketoconazole and propose clinical guidelines for selecting the proper chemotherapeutic agent and for following the efficacy of the treatment regimen.
Towards transparent and efficient software distributed shared memory (1997)

Despite a large research effort, software distributed shared memory systems have not been widely used to run parallel applications across clusters of computers. The higher performance of hardware multiprocessors makes them the preferred platform for developing and executing applications. In addition, most applications are distributed only in binary format for a handful of popular hardware systems. Due to their limited functionality, software systems cannot directly execute the applications developed for hardware platforms. We have developed a system called Shasta that attempts to address the issues of efficiency and transparency that have hindered wider acceptanceof software systems. Shastais adistributedsharedmemory system that supports coherence at a fine granularity in software and can efficiently exploit small-scale SMP nodes by allowing processes on the same node to share data at hardware speeds.

Improvement in ozone tolerance of tobacco plants with an antisense DNA for 1‐aminocyclopropane‐1‐carboxylate synthase (2002)

Abstract Antisense DNA for an ozone‐inducible 1‐aminocyclopropane‐1‐carboxylate (ACC) synthase (EC 4.4.1.14; LE‐ACS6) from tomato, under the control of the cauliflower mosaic virus 35S promoter, was introduced into tobacco to generate transgenic plants. Lower rates of ozone‐induced ethylene production were observed in three of seven transgenic plants than in the wild‐type plants. Ozone‐induced visible damage was attenuated in these three lines, and the extent of damage was positively related to the level of ozone‐induced ethylene production. In the most ozone‐resistant line, ozone‐induced accumulation of ACC and levels of transcripts for ozone‐inducible endogenous ACC synthases were suppressed compared with those in wild‐type plants, demonstrating that ozone‐inducible ACC synthases have a key role in the expression of leaf damage by ozone exposure. No significant differences in growth and morphology were observed between transgenic and wild‐type plants. Stomatal conductance of transgenic plants during ozone exposure was higher than that of wild‐type plants. These findings indicate that the introduction of antisense DNA for an ozone‐inducible ACC synthase can improve the ozone tolerance of plants without reducing their gas absorption and productivity.
Physician Payments from Industry Are Associated with Greater Medicare Part D Prescribing Costs (2016)

While distribution and amount of payments differed widely across medical specialties, for each of the 12 specialties examined the receipt of payments was associated with greater prescribing costs per patient, and greater proportion of branded medication prescribing. We cannot infer a causal relationship, but interventions aimed at those physicians receiving the most payments may present an opportunity to address prescribing costs in the US.
Diagnostic accuracy of [18F]-fluoro-l-dihydroxyphenylalanine positron emission tomography scan for persistent congenital hyperinsulinism in Japan (2011)

In contrast to the results of previous reports, [(18)F]DOPA PET appears to be less efficient for diagnosing Japanese patients with congenital hyperinsulinism. However, the diagnostic accuracy is substantially improved when this technique is combined with the Pancreas Percentage.
