Appointment scheduling in healthcare

In the modern appointment scheduling literature various approaches have been proposed. Some of them are simulation-based, but these have the obvious shortcoming that the resulting guidelines tend to be case-specific. Other approaches cannot handle relevant characteristics of healthcare processes. The goal of this dissertation is to develop an appointment scheduling methodology that covers realistic healthcare settings, and that outperforms existing methods. The main idea behind our approach is to cast appointment scheduling in a queueing-theoretic framework where an objective function is minimized. To overcome the intrinsic complexity of the problem we study various simplification approaches. In the first place, we approximate the service times by their phase-type counterparts, thus facilitating a fast and efficient recursive procedure for the evaluation of the objective function. We show in detail how various healthcare-specific features, such as walk-ins and no-shows, can be incorporated in this approach. Furthermore, we extend the framework from a single service provider to a two-node tandem system. Besides the phase-type approach, we have developed an alternative approach that uses the actual service-time distribution. In addition, we consider the steady-state version of the appointment scheduling problem, corresponding with the situation in which a large number of patients are scheduled. For this limiting setting we provide insightful analytical results relying on a heavy-traffic approximation. Our general conclusion is that the preferred technique is the phase-type approach, which outperforms competing approaches in the literature almost uniformly. We provide a webtool that implements this approach, which can be used directly by practitioners in healthcare.
Refactoring FrameNet for Efficient Relational Queries

The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.
A random access photodiode array for intelligent image capture

A novel chip implementing random scan was designed, fabricated and tested. The chip covers the basic requirements for random access and separation between the sampling and reading processes. In this way a repeated reading of any pixel at any time can take place. The chip includes an 80*80 matrix of basic cells. Each cell consists of two stages: the first is based on a switch, while the second includes a buffer. The chip, fabricated in a 3 mu cMOS process, was found to operate functionally. However, the use of a standard process gave rise to crosstalk which has yet to be overcome. <<ETX>>
Apport des corticotomies alvéolaires dans les traitements orthodontiques par aligneurs : à propos d'un cas clinique

Au cours de la derniere decennie, un nouveau moyen therapeutique est apparu en orthodontie : les aligneurs amovibles et transparents. Plus esthetique et confortable, le traitement orthodontique par aligneurs est mieux accepte par les patients adultes. Cependant, dans sa revue systematique, Rossini (1) a montre que leur efficacite restait limitee pour certains mouvements (extrusion, torque, rotation). Parallelement, une nouvelle technique chirurgicale nommee « corticotomie alveolaire » s’est developpee. Le but est d’accelerer et faciliter le deplacement dentaire provoque en realisant une decortication alveolaire selective. Grâce a cette decortication combinee a une augmentation par greffe osseuse, l'enveloppe des mouvements possibles est etendue et le parodonte est renforce par augmentation de l’epaisseur corticale (2). L'association des aligneurs et des corticotomies alveolaires pourrait permettre d'ameliorer les resultats obtenus par aligneurs. Peu de publications sur cette association ont ete publiees dans la litterature mais Casseta (3) decrit un traitement d'une classe I avec dysharmonie dento-arcade en seulement 2 mois.
Statistical Inferences from the Topology of Complex Networks

Abstract : Topological data analysis provides machinery for summarizing the topology of complex data. The main goal of this project was to develop a new summary compatible with statistics and machine learning. This goal was met with the development of a new summary, the persistence landscape. This summary is stable, does not lose any information, has continuous and discrete versions, and obeys a strong law of large numbers and a central limit theorem. All of the standard tools in statistics and machine learning are available for subsequent analysis. For example, one can easily calculate averages and differences, apply principal component analysis and support vector machines, or feed these results into a neural network. The secondary goal of the project was to help place Topological Data Analysis on a firmer mathematical foundation, strengthening its connections to mathematics and making it easier for researchers to leverage mathematical results for analyzing complex data and complex networks. This goal has been met with the development a very general framework for topological data analysis. Both of these developments have led to much work by other researchers.

Evolución y situación epidemiológica de la infección por virus de inmunodeficiencia humana y síndrome de inmunodeficiencia adquirida en Chile

: In Chile, the first cases of AIDS were reported 23 years ago, and since then, through December 2006, 17.235 persons have been notified with HIV infection or AIDS1. To the year 2005, there have been 5.288 fatal cases of AIDS. The last available data indicates that notification rates for AIDS and HIV infection in 2006 were 2.5 and 4.5 per 100.000 inhabitants, respectively, and mortality rate for AIDS in 2005 was 2.4 per 100.000 inhabitants. Trend analysis shows a decline in the notification rate among men, both for HIV infection and AIDS, which could be a real decrease or a sub notification bias. In Chile, like in other countries of the region, variations in the epidemiologic pattern were observed considering age group, gender, educational level and geographic distribution of the population. Currently, the Chilean Ministry of Health has implemented both a surveillance and monitoring system on line, in order to improve the quality and opportunity of the information, therefore providing an important tool to HIV infection/AIDS prevention and control strategies.

Fast Marching Methods and Level Set Methods: An Implementation

A wide variety of problems can be formulated as an interface propagation. Some examples are burning flames, waves in water and physical boundaries. The fast marching methods and narrow band level set method are useful for finding a solution to these problems. The fast marching method is associated with the boundary value problem, and as such can only be used for a propagation which strictly expands or contracts. It is in contrast with the narrow band level set method, which is associated with the initial value formulation; it can be used for the propagation of interfaces which both expand and contract. There is a parallel of both of these problems to general wave equations. Thus, by solving the Hamilton-Jacobi equation with an appropriate flux function, numerical approximation schemes for both propagation methods can be naturally formulated in a way such that the correct solution is obtained. The final formulation of the two algorithms proves to be both robust and efficient, although they do not produce a very accurate solution using first order approximations.
Cochlear nuclei neuroplasticity after auditory nerve and cochlea removal

Hearing loss clearly alters the function and connectivity in auditory pathways in the brain. The effects of an auditory receptor lesion on the auditory pathway might be linked to the absence of peripheral stimulation on the first level of the auditory pathway (cochlear nuclei, CN). Loss of stimulation affects the pathway connectivity, at least in the CN, inducing the reorganization of the neural circuits. This reorganization may reduce the efficiency of some deafness therapies, including cochlear implants. Cochlea removal has been shown to be a good model for analysing neuroplasticity in the CN. Three main periods of degeneration and regeneration were found after cochlea removal. During the first week after cochlea removal, early effects included auditory nerve fibre degeneration, and the progressive degeneration of nerve endings on CN neurons. Some CN neurons degenerate. From the second week after cochlea removal a very limited and diffuse expression of GAP-43, a protein linked to developing or regenerating axon growth cones, was found. Expression was observed in small nerve endings connecting cochlear nuclei neurons. One month after cochlea removal, CN were stabilized with a clear reduction of new neuron degeneration. At this time a very relevant expression of GAP-43 was found around remaining neurons, in particular in the ventral cochlear nuclei. Molecular aspects and control of neuroplasticity in cochlear nuclei still remains controversial, even though it is clear that trophic factors and many other substances (i.e. neurotransmitters) have been involved in neuroplasticity.
Linfoma tiroideo, un dilema diagnóstico

Dadas las implicancias diagnostico-terapeuticas de una tumoracion de rapido crecimiento en tiroides, esta situacion debe hacer pensar en cancer indiferenciado y linfoma tiroideo (LT), entidad de baja frecuencia que representa un desafio diagnostico para el equipo medico. Los mas frecuentes son los linfomas no Hodking tipo B (LNHB). La alta tasa de proliferacion celular los hace sensibles al tratamiento con poliquimioterapia (PQT). Objetivo: se presenta el caso clinico de un LT primario cuya clasificacion inmunohistoquimica (IHQ) es cuestionable. Conclusion: el LT es inusual, se descartara frente a una masa tiroidea, de rapido crecimiento, planteandolo siempre como diagnostico diferencial. El tratamiento debe realizarse con equipo multidisciplinario, en base a PQT inicial y radioterapia, siendo la cirugia una terapeutica controversial.
Efficient VLSI module placement with solution space smoothing

Due to the rugged terrain surface of the search space of a placement instance, it often is stuck at a locally optimum configuration. In this paper, we propose a solution space smoothing technique for VLSI block placement. A placement instance with the simplest terrain structure is solved first, and the original problem instance with more complicated terrain structure is solved last. The solutions of the simplified problem instances are used to guide the search of more complicated ones. Compared with the simulated annealing algorithm, the solution space smoothing method needs few control parameters and the parameters are easy to determine. Experimental results of MCNC benchmarks show that solution space smoothing is very efficient for VLSI module placement. It can be applied to floorplanning representations, such as BSG, SP, CBL, B*-tree, O-tree, etc.
Atypical Frontotemporal Connectivity of Cognitive Empathy in Male Adolescents With Conduct Disorder

Background: It has been suggested that adolescents with conduct disorder (CD) may have a deficit in the affective and cognitive domains empathy, but studies exploring networks within the key brain regions of affective and cognitive empathy in adolescents with CD are lacking. Methods: Functional connectivity (FC) analyses among key brain regions of the affective and cognitive empathy with resting-state functional magnetic resonance imaging (fMRI) were conducted in 30 adolescent boys with CD and 33 demographically matched healthy controls (HCs). Results: Atypical FC within the key brain regions of affective empathy was not observed in CD adolescents. However, we found that CD adolescents showed decreased frontotemporal connectivity within the key brain regions of cognitive empathy in relation to HCs, that is, the FCs between right temporoparietal junction and ventromedial prefrontal cortex as well as dorsomedial prefrontal cortex. Conclusion: These findings may provide insight into neural mechanism underlying a cognitive empathy deficiency of CD adolescents from the perspective of FC.
Evaluation of intra-flow contention in MANET

In mobile ad hoc networks (MANET) with contention-based MAC, the nodes along a path of transmission contend for access the medium in a distributed manner, this leads to intra-flow contention that cause degradation in the network performance. The precision for determining the intra-flow contention helps any contention-based admission control to make correct decisions to admit or reject any new flows, and in turn improves the performance of the network. However, the calculation of the intra-flow contention is challenging, because the nodes only know their neighbors that are located within the transmission range, but do not aware about those are located between the edge of the carrier sense range and the transmission range, or those are located within interference range of the receiver. This paper analysis the intra-flow contention and evaluates the existing methods in the literature for calculating the contention count. The analysis shows that, the current methods still have limitation in term of the covered area for calculating the intra-flow contention, they also have considerable overhead and delay that cause impact on the throughput in MANETs.
Sex Determination Using Three-Dimensional Computed Tomography of Pelvis Measurements in Adult Egyptian population..

Background: Sex identification of unknown skeletal human remains is of great importance in establishing identity and individuality. In adults, hip bone is the most reliable sex indicator because of its sexual dimorphism. Each population should have its own specific standards of identification. Objectives: Develop a logistic regression formula for adult sex identification using three-dimensional computed tomography (3D-CT) of the pelvis, and assessment of its validity in sex determination among a sample of Egyptian population at Suez Canal region. Materials and Methods: 141 pelvi-abdominal CT images (free of any pelvic orthopaedic disorder) were included; they were reconstructed to produce 3D-CT pelvic images; they were divided into calibration group (47 male & 47 female) and test group (47 CT images their sex is unknown to the observer), twenty radiometric variables were measured for the calibration groups. A logit response formula for sex prediction was developed and applied on the test group for sex prediction. Results: The logit response formula for the test sample showed sensitivity, specificity and overall accuracy 100%. Conclusion; Proposed method represent a quick and reliable metric method in establishing sex from the pelvis.
Low-voltage high-speed switched-capacitor circuits without voltage bootstrapper

Low-voltage high-speed switched-capacitor (SC) circuit design without using voltage bootstrapper is presented. The basic building block used for low-voltage SC circuit design is the auto-zeroed integrator (AZI), which can work at both low voltage and high sampling frequency. With this method, two low-voltage SC systems were successfully designed and implemented in 1.2-/spl mu/m CMOS technology. The first one is a fully differential SC bandpass biquad working at 1.5 V and 5.0-MHz clock frequency. The measured Q value is 8.0 at the center frequency of 833 kHz. The second one is a fully differential fourth-order bandpass /spl Delta//spl Sigma/ modulator that also works at 1.5 V and 5.0 MHz. Its measured third-order intermodulation is less than -78 dBc due to the low distortion characteristic of AZI. The measured signal-to-noise ratio of the modulator is 61 dB within the narrow band of 25 kHz centered at 1.25 MHz.
Vowel systems of the Manchu-Tungus languages of China

This dissertation presents a study of the vowel phonology of the Manchu-Tungus languages of China--Manchu, Xibe, Hezhen, Oroqen and Ewenki. The Manchu-Tungus languages belong to the Altaic family. By comparing the Written Manchu (Classical Manchu) harmony system with the vowel systems of spoken Manchu. Manchu-related Xibe and Hezhen, and other Tungusic languages. I argue that the vowel system of Written Manchu is a tongue root system, solving the controversy about the harmony pattern of this language. With the tongue root system assumption, other aspects of the vowel phonology of written Manchu, including its diphthong systems and vowel-related consonant alternations, are very well explained. Based on first-hand materials, the dissertation offers a detailed description and explanation of the vowel phonology of the Oroqen language, including its vowel system, harmony patterns, palatalization and labialization caused by vowels, and constraints on vowel length. The thesis proposes a syllable condition on labial harmony in Written Manchu and Oroqen of a type that has not been previously noticed in the study of vowel harmony. I compare the vowel systems and harmony patterns of the whole Manchu-Tungus language group. I conclude, from both synchronic and diachronic perspectives, that the change from a system with tongue root contrasts to a system with height contrasts is a natural process, providing support to the proposal that the proto-harmony system of the Tungusic languages is one with tongue root harmony. Within the framework of contrastive specification, I argue that the phonological processes of vowels in the Manchu-Tungue languages of China are based on the underlying representations of segments, which are determined by the contrasts in the inventory. I present harmony patterns of the Manchu-Tungus languages in China in a systematic way. The approximately three hundred cognate words of these languages that I collected make available a comparative study of the Manchu-Tungus languages as a whole. Sociolinguistic aspects of the Manchu-Tungus languages of China, as well as the linguistic features of these languages discussed in the dissertation, help to make a correct classification of the languages of the whole Tungusic group.

Insulinothérapie par pompes portables et implantables

Les pompes a insuline ont ete developpees pour mimer l'insulinosecretion, mal reproduite par les injections discontinues. Les pompes portables utilisant la voie sous-cutanee peuvent etablir un controle glycemique proche de la normale au long cours chez les diabetiques de type 1, reduisant l'incidence des complications microangiopathiques et neuropathiques, ainsi que leur aggravation. Cependant, leur effet preventif sur les hypoglycemies severes est controverse et le risque d'acido-cetose est accru. L'insuline lispro ameliore leur efficacite, les positionnant comme la methode d'insulinotherapie sous-cutanee la plus performante. Indiquees en cas d'echec des multi-injections, les pompes portables sont contre-indiquees en cas de retinopathie ischemique non controlee, et chez les sujets a risque d'erreur dans la conduite du traitement pour des raisons psychologiques, comportementales ou d'absence de motivation. Les pompes implantables utilisent la voie intra-peritoneale, plus physiologique. Elles permettent un controle glycemique plus stable, avec une incidence faible d'hypoglycemies severes. Les incidents au site d'implantation et les obstructions du catheter peritoneal demeurent les limites de ces systemes. Leur couplage possible avec un detecteur de glucose implante les positionne dans la perspective du pancreas artificiel implantable.
Inflammatory arthritis of distal interphalangeal joints in rheumatoid arthritis; a rare case report

Rheumatoid arthritis (RA) is autoimmune inflammatory arthritis of unknown etiology. The involvement of distal interphalangeal joint in RA is rare and review of literature does not reveal much about inflammatory arthritis of distal interphalangeal joint in RA with joint destruction. We report a case of seropositive RA with severe distal interphalangeal joint destruction.
Real‐time hand gestures system based on leap motion

In the three‐dimensional human‐computer interaction, the identification of dynamic and static gestures is a very important and challenging work in the field of machine vision, In this paper, we propose a new gesture recognition system. Leap Motion device is a kind of equipment, which is specially used for hand recognition, which can get the feature data to realize the gesture recognition in real time. The system is mainly composed of the following two parts. For static gestures, we use a kind of feature information based on the distance, direction, and bending degree of the fingertip, and bring the support vector machine into the training to realize the static gesture recognition. For dynamic gestures, we use gesture length as a benchmark to reject non‐key gestures and preprocess frames with abnormal gesture sequences. The average recognition rate of static gestures reaches 99.98%, and the recognition rate of dynamic gestures reaches 96.20%. The experimental results show that the algorithm has a good effect on gesture recognition, and it is suitable for the simple interaction between gestures, people and people and daily communication of daily communication barriers.
Library Suggestions and Typologies of Information Needs

This paper explores the strengths and weaknesses of investigating information needs through scrutiny of library suggestions made by users. The method is attractive in drawing upon material that many libraries collect routinely and which may be used to present a picture of need that cannot easily be gained through other techniques. Nevertheless, insights achieved via suggestions analysis typically relate only to the library itself and often to its perceived weaknesses. There are ethical questions surrounding the use of suggestions data out of context, and researchers cannot know in advance that sufficient data relevant to their information needs focus will be elicited. Investigators must also decide on their stance regarding the wider applicability of their findings. Despite all these issues, suggestions data can play a pivotal role in inspiring the development of subsequent research into information needs, and may have considerable value when used in concert with other methods.
