Context-aware clustering (2008)

Most existing methods of semi-supervised clustering introduce supervision from outside, e.g., manually label some data samples or introduce constrains into clustering results. This paper studies an interesting problem: can the supervision come from inside, i.e., the unsupervised training data themselves? If the data samples are not independent, we can capture the contextual information reflecting the dependency among the data samples, and use it as supervision to improve the clustering. This is called context-aware clustering. The investigation is substantialized on two scenarios of (1) clustering primitive visual features (e.g., SIFT features) with help of spatial contexts, and (2) clustering ‘0’–‘9’ hand written digits with help of contextual patterns among different types of features. Our context-aware clustering can be well formulated in a closed-form, where the contextual information serves as a regularization term to balance the data fidelity in original feature space and the influences of contextual patterns. A nested-EM algorithm is proposed to obtain an efficient solution, which proves to converge. By exploring the dependent structure of the data samples, this method is completely unsupervised, as no outside supervision is introduced.
Swimming (2020)

This chapter recounts my teaching of a swimming session in which I focused on a very technical aspect of the kick in butterfly to provide an example of how Positive Pedagogy for sport coaching (PPed) can be used to coach technical aspects of sport. Although there is a tactical element in most swimming events, technique is of pivotal importance and has to form the main focus when coaching young swimmers in particular, but mechanistic coaching is not the only way to do this. Underpinned by the philosophic positions of humanism and holism, PPed provides one way of coaching that can account for the complexity of swimming with this chapter providing an example of its use in swim coaching. The aim of the session was to develop the swimmers’ awareness of this part of the kick and assist them in understanding how it fits into the whole stroke and to improve its contribution to their stroke.
The many faces of ion-exchange resins (1997)

Ion-exchange resins have been used commercially for over 60 years. Softening and demineralization of water for boiler feed and process use were then, and continue to be, the most familiar and widespread applications of ion-exchange resins throughout the chemical process industries (CPI). Several types of membrane-based technologies, such as electrodialysis, reverse osmosis and, more recently, electrodeionization are recognized as alternative methods for water treatment. Yet, modern versions of ion-exchange resins remain a major player in water treatment. In addition, these versatile materials can be found performing a wide range of tasks in both aqueous and nonaqueous environments. Some of these diverse applications include: acid or base catalysis; manufacture of high-purity solvents and reagent chemicals; separation of by-products of fermentation processes; deacidification of organic solvents; high-purity water production for semiconductor manufacture; recovery of valuable waste from dilute process effluents; controlled release of pharmaceutical products; and chromatography, both on the analytical and the industrial scale. The key to understanding the potential of ion-exchange resins is to look beyond their exchange and adsorptive characteristics, and to see their fundamental nature. In other words, it`s necessary to first consider them as spherical, particulate reactive polymers that perform chemical reactions.
A Fast and Accurate Feature-Matching Algorithm for Minimally-Invasive Endoscopic Images (2013)

The ability to find image similarities between two distinct endoscopic views is known as feature matching, and is essential in many robotic-assisted minimally-invasive surgery (MIS) applications. Differently from feature-tracking methods, feature matching does not make any restrictive assumption about the chronological order between the two images or about the organ motion, but first obtains a set of appearance-based image matches, and subsequently removes possible outliers based on geometric constraints. As a consequence, feature-matching algorithms can be used to recover the position of any image feature after unexpected camera events, such as complete occlusions, sudden endoscopic-camera retraction, or strong illumination changes. We introduce the hierarchical multi-affine (HMA) algorithm, which improves over existing feature-matching methods because of the larger number of image correspondences, the increased speed, and the higher accuracy and robustness. We tested HMA over a large (and annotated) dataset with more than 100 MIS image pairs obtained from real interventions, and containing many of the aforementioned sudden events. In all of these cases, HMA outperforms the existing state-of-the-art methods in terms of speed, accuracy, and robustness. In addition, HMA and the image database are made freely available on the internet.
Directed Self-Assembly of Dipeptides to Form Ultrathin Hydrogel Membranes (2010)

The dipeptide amphiphile Fmoc-Leu-Gly-OH has been induced to self-assemble into thin surface-supported hydrogel gel films and gap-spanning hydrogel membranes. The thickness can be closely controlled, giving films/membranes from tens of nanometers to millimeters thick. SEM and TEM have confirmed that the dipeptides self-assemble to form fibers, with the membranes resembling a dense "mat" of entangled fibers. The films and membranes were stable once formed. The films could be reversibly dried and collapsed, then reswollen to regain the gel structure.
Resonance in the kidney system of rats (1994)

The pressure wave of the abdominal aorta and the flow wave of the renal artery were recorded simultaneously from a rat. The impedance of a kidney system that is derived by dividing the pressure of the corresponding frequency by that of the flow was studied in six rats. The data show that the system has two resonant frequencies, at the second and third harmonics. At the second harmonic, the pressure wave and fluid flow in a round trip through the branch of the kidney. Whereas it is difficult for the third harmonic flow to enter the kidney, it flows directly through the aorta. To obtain further proof, we compared the frequency components of the two flows measured simultaneously on the abdominal aorta and the renal artery and found the same result. The kidney, renal artery, and aorta combined show a coupled oscillation that is analogous to that of resonance circuits. The kidney vascular system exhibits a resonant frequency at the second harmonic of the heartbeat.

Postchallenge Hyperglycemia in a National Sample of U.S. Adults With Type 2 Diabetes (2001)

These data suggest that PCH is common among diabetic adults in the U.S., even in the setting of "optimal" glycemic control and sulfonylurea use. Interventions designed to lower postprandial glucose excursions may help improve overall glycemic control in the general population of U.S. adults with diabetes.
Progress in Impulse Testing of Transformers (1944)

Impulse testing of transformers has resulted in improvement of design and manufacturing methods. Not only should the test methods now given in American Standard C57.2 be simplified to effect a reduction in cost of tests, but the test code should be modified to give an adequate assurance of failure detection. The importance of failure detection and means available at present are discussed at length. A new method is proposed which is more sensitive than the older methods and appears to be less subject to individual interpretation.
A BPMN extension for modeling non functional properties of business processes (2011)

Business Process Management (BPM) is an holistic approach for describing, analyzing, executing, managing and improving large enterprise business processes, which can be seen as collections of related tasks executed to accomplish well-defined goals. This paper introduces a notation for the description of a business process in terms of both functional and non-functional properties, specifically addressing the performance and reliability characterization of a business process. In the BPM context, the Business Process Modeling Notation (BPMN) is the de-facto standard for the high-level description of business processes. Unfortunately BPMN does not support the characterization of the business process in terms of non-functional properties such as performance and reliability. To overcome such limitation, this paper introduces PyBPMN (Performability-enabled BPMN), a lightweight BPMN extension for the specification of properties that address both performance and reliability. The proposed extension is based on an approach that exploits principles and standards introduced by the Model Driven Architecture (MDA), thus obtaining significant advantages in terms of easy customization and improved automation. The paper also presents an example application of the proposed extension to show how it enables the automated transformation of a business process model into a parameterized performance model whose execution gives insights about the process behavior.
Safety standards for human exposure to radio frequency radiation and their biological rationale (2003)

Exposure guidelines for RF radiation have been promulgated for nearly half a century. However, our understanding of biological effects of exposure to RF radiation is still evolving and more so for cellular mobile telephones and wireless personal communication devices. There are two different sets of guidelines promulgated for limiting human exposure to RF radiation, worldwide. Currently, there is a backdrop of persistent, publicly expressed lack of confidence in radio-frequency (RF) exposure standards, pertaining to the maximum permissible exposure (MPE) level of humans exposed to RF electromagnetic radiation. Much of the current effort is driven by the advent of cellular mobile telephony, which uses RF radiation in the range of 800-2,500 MHz. The setting of guidelines or standards for maximum permissible levels of exposure to RF and microwave radiation is a valid approach to managing the risk of such exposures. The existing guidelines, however, are based on results obtained from acute, short-term studies that are atypical of the RF exposures associated with the handset of cellular mobile telephones. For the first time in human history, a source of RF radiation is located right next to the head of millions of cellular mobile telephone users. Biological effects after repeated, prolonged, or lifelong exposure to RF energy emitted by these low-power wireless telecommunication devices have been investigated only during the past few years. The existing scientific results are equivocal and arguable in many respects. Consequently, there remains a widespread public concern about the adequacy of existing guidelines in safeguarding the general population against possible harm of RF radiation from cellular mobile telephones.
Model for thermal spreading impedance in GaAs MESFETs (2002)

A simulation model for dynamic temperature response in GaAs MESFET structures is presented. In the model, the heated volumes below the gate fingers are constructed of heated spheres. Analytic formulas for the thermal spreading impedance at any point in the device are presented. These formulas are realized with a simple linear electrical equivalent circuit that can be used as the thermal part of an electrothermal MESFET model. By means of this electrical equivalent circuit, the model is applicable in all analysis modes of a circuit simulator. The model behaviour is demonstrated here with DC, AC and transient simulations.
« Mon Père travaille toujours », Jean, 5, 17 et la tradition des Logia de Jésus (1995)

Le logion de Jn 5, 17 pourrait être une formulation johannique inspirée de deux paroles anciennes, l'une liée à la parabole des deux fils, l'autre en rapport avec la polémique sur le sabbat. Le motif du père et du fils et celui du « travailler » proviendraient d'une reprise de la tradition des paraboles sur le fils. Jean les réinterprète dans sa narration et s'appuie sur eux pour bâtir sa christologie du fils envoyé.
[Comparative evaluation of the effects of crystalloid solutions containing sodium lactate and sodium succinate on the hemodynamic indicators in different types of hemorrhage]. (1991)

The results are presented of the hemodynamics investigations under the influence of two saline infusion solutions in varying types of hemorrhage. The suggested crystalloid solution succinasol contains sodium succinate (instead of lactate that is present in lactasol) which improves energetic processes in tissues under conditions of circulatory hypoxia. The results of the study of hemodynamics parameters and animal survival rate have shown succinasol advantages as compared to the lactate-saline blood substitute in acute massive hemorrhage and reversible hemorrhagic shock.
Intragastric Balloon: Ethics, Medical Need and Cosmetics (2007)

The development of the intragastic balloon as a safe, noninvasive, alternative method to weight reduction raises all the ethical questions routinely faced by practitioners of other forms of cosmetic surgery. In the case of the morbidly, severely or merely obese, the surgeon is faced with a medical decision in a situation defined by medical parameters. The case of the overweight or normal may, however, create an ethical dilemma in which the doctor is forced to make decisions of a nonmedical nature, for which his training has not prepared him, and relating essentially to his personal attitudes and moral beliefs, culture and the recognition that 'if I don't, somebody else--possibly less competent--will'.
Digital Paper with Guest-Host type Liquid Crystal Medium (2003)

Digital Paper was recently proposed as a new medium that offers the advantages of both softcopy and hardcopy. This study examines the possibility of realizing Digital Paper by using an ion projection head to drive a liquid crystal medium. A guest-host type liquid crystal sheet medium is prepared. An ion projection head with charge dot density of 300 dpi is used for surface charging. It is confirmed that white images could be repeatedly formed on a black background by ion projection followed by image erasure (by heating) to the black background. It is demonstrated that this sheet medium has ideal characteristics; it reproduces the viewing angle and flexibility of paper. This method is thus promising as a candidate for realizing Digital Paper.
Bis(diazadien)metall(O)-Komplexe, III. Nickel(O)-bis(chelate) mit aliphatischen N-Substituenten/ Bis(diazadien)metal(O) Complexes, III. Nickel(O)-bis(chelates) with Aliphatic N-Substituents (1981)

Abstract Diazadienes (DAD) (with R 1 , R 2 = H, CH 3 and R 3 , R 4 = alkyl) form nickel complexes 1-14 with composition (DAD) 2 Ni. They can be prepared by ligand substitution from other Ni(O) compounds or, preferably, by the reduction of Ni(II) salts in the presence of DAD. Spectroscopic differences (NMR, UV) indicate different structures (type 1 and 2) for diamagnetic (DAD) 2 Ni of same composition, depending on substituents R 1 -R 4 . The steric requirement of R 3 , R 4 is most important as the main differences show up when going from tertiary (type 1: R 2 CH-N = ) to secondary a-carbon (type 2: RCH2-N = ) . X-ray analysis of a type 1 complex (R 1 , R 2 = H, R 3 , R 4 = cyclo-hexyl) reveals two strictly orthogonal chelate rings (D 2d ) corresponding to (pseudo-)tetrahedrally coordinated Nickel(O). A D 2 -structure with smaller dihedral angle is discussed for type 2 complexes.
Auto-Encoding Scene Graphs for Image Captioning (2018)

We propose Scene Graph Auto-Encoder (SGAE) that incorporates the language inductive bias into the encoder-decoder image captioning framework for more human-like captions. Intuitively, we humans use the inductive bias to compose collocations and contextual inference in discourse. For example, when we see the relation `person on bike', it is natural to replace `on' with `ride' and infer `person riding bike on a road' even the `road' is not evident. Therefore, exploiting such bias as a language prior is expected to help the conventional encoder-decoder models less likely overfit to the dataset bias and focus on reasoning. Specifically, we use the scene graph --- a directed graph ($\mathcal{G}$) where an object node is connected by adjective nodes and relationship nodes --- to represent the complex structural layout of both image ($\mathcal{I}$) and sentence ($\mathcal{S}$). In the textual domain, we use SGAE to learn a dictionary ($\mathcal{D}$) that helps to reconstruct sentences in the $\mathcal{S}\rightarrow \mathcal{G} \rightarrow \mathcal{D} \rightarrow \mathcal{S}$ pipeline, where $\mathcal{D}$ encodes the desired language prior; in the vision-language domain, we use the shared $\mathcal{D}$ to guide the encoder-decoder in the $\mathcal{I}\rightarrow \mathcal{G}\rightarrow \mathcal{D} \rightarrow \mathcal{S}$ pipeline. Thanks to the scene graph representation and shared dictionary, the inductive bias is transferred across domains in principle. We validate the effectiveness of SGAE on the challenging MS-COCO image captioning benchmark, e.g., our SGAE-based single-model achieves a new state-of-the-art $127.8$ CIDEr-D on the Karpathy split, and a competitive $125.5$ CIDEr-D (c40) on the official server even compared to other ensemble models.

Mechanism of monocyte-macrophage-mediated transmission of HIV. (1998)

Observations from our laboratory support the theory that HIV-infected monocyte-macrophages present in genital tract secretions have an important role in sexual transmission of HIV. Light and electron microscopy were used to study the behavior of HIV-infected, primary human monocytes. These cells progress on surfaces, putting forward a leading pseudopod from which they secrete HIV. When added to cultures of CD4-, cervix-derived epithelial cells, monocytes advanced between epithelial cells while secreting virus anteriorly. Epithelial cells subsequently become productively infected. Infection of epithelia could be blocked by sera from HIV-seropositive individuals. These findings support the supposition that transmission of HIV may occur via cell-mediated infection of intact epithelia. The observations also hint at the possibility that HIV-infected monocyte-macrophages in semen or cervical-vaginal secretions could cross intact epithelia by passing between epithelial cells. To test this hypothesis supravital-stained mouse macrophages were inoculated into the vaginas of mice. Four hours later numerous stained cells were observed in the connective tissue beneath the vaginal epithelium and in the iliac lymph nodes. We speculate that direct infection of epithelial cells and/or cell trafficking across epithelia may be involved in sexual transmission of HIV.
Study of the Stakeholder's Proactive Attitude in the Decision-Making Process regarding the Reorganization of the Public Health System in Romania (2013)

The paper approaches the public health sector changes according to the latest legislative regulations proposed for Romanian hospitals. The first part of the work offers a global view of these new normative acts package and its opportunity, considering both the current needs of the population and the external pressure of progressing in this field. The research is focused on measuring the stakeholders’ involvement in this process, and their capacity of keeping objectivity high when they are directly influenced by new legal frame under discussion. The study focuses on knowing the orientation of the stakeholders towards: their awareness of the real necessities, their openness for change, their proactive behavior, and also their availability to get involved in the decision-making process. The research methodology is based on qualitative and quantitative methods used to collect and process the data obtained. The results presented and analyzed in the last part of the paper are interesting and useful for the decision makers and for the Romanian regulation authorities too. Also, the data base provides specific information for comparative studies in the future, between different institutions, or for the same institution after a certain period, analyzing the achieved progress. The paper concludes with some important and relevant findings for researchers and employees of public institutions in the field.
