Subfield-Subcodes of Generalized Toric codes

We study subfield-subcodes of Generalized Toric (GT) codes over $\mathbb{F}_{p^s}$. These are the multidimensional analogues of BCH codes, which may be seen as subfield-subcodes of generalized Reed-Solomon codes. We identify polynomial generators for subfield-subcodes of GT codes which allows us to determine the dimensions and obtain bounds for the minimum distance. We give several examples of binary and ternary subfield-subcodes of GT codes that are the best known codes of a given dimension and length.Comment: Submitted to 2010 IEEE International Symposium on Information Theory (ISIT 2010

Rgtsp: a generalized top scoring pairs package for class prediction.

SUMMARY: A top scoring pair (TSP) classifier consists of a pair of variables whose relative ordering can be used for accurately predicting the class label of a sample. This classification rule has the advantage of being easily interpretable and more robust against technical variations in data, as those due to different microarray platforms. Here we describe a parallel implementation of this classifier which significantly reduces the training time, and a number of extensions, including a multi-class approach, which has the potential of improving the classification performance. AVAILABILITY AND IMPLEMENTATION: Full C++ source code and R package Rgtsp are freely available from http://lausanne.isb-sib.ch/~vpopovic/research/. The implementation relies on existing OpenMP libraries

The evaluation of liver fibrosis regression in chronic hepatitis C patients after the treatment with direct-acting antiviral agents – A review of the literature

The second-generation of direct-acting antiviral agents are the current treatment for chronic viral hepatitis C infection. To evaluate the regression of liver fibrosis in patients receiving this therapy, liver biopsy remains the most accurate method, but the invasiveness of this procedure is its major drawback. Different non-invasive tests have been used to study changes in the stage of liver fibrosis in patients with chronic viral hepatitis treated with the second-generation of direct-acting antiviral agents: liver stiffness measurements (with transient elastography or acoustic radiation force impulse elastography) or different scores that use serum markers to calculate a fibrosis score. We prepared a literature review of the available data regarding the long-term evolution of liver fibrosis after the treatment with direct-acting antiviral agents for chronic viral hepatitis C

An approach to implementing dynamic adaptation in c

This paper describes TRAP/C++, a software tool that enables new adaptable behavior to be added to existing C++ programs in a transparent fashion. In previous investigations, we used an aspectoriented approach to manually define aspects for adaptation infrastructure, which were woven into the original application code at compile time. In follow-on work, we developed TRAP, a transparent shaping technique for automatically generating adaptation aspects, where TRAP/J is a specific instantiation of TRAP. This paper presents our work into building TRAP/C++, which was intended to be a port of TRAP/J into C++. Designing TRAP/C++ required us to overcome two major hurdles: lack of reflection in C++ and the incompatibility between the management of objects in C++ and the aspect weaving technique used in TRAP/J. We used generative programming methods to produce two tools, TrapGen and TrapCC, that work together to produce the desired TRAP/C++ functionality. Details of the TRAP/C++ architecture and operation are presented, which we illustrate with a description of a case study that adds dynamic auditing capabilities to an existing distributed C++ application

Early diagnosis and prompt surgical treatment – the key to favorable results in Boerhaave Syndrome

Spitalul Județean de Urgență, Drobeta-Turnu Severin, România, Al XIII-lea Congres al Asociației Chirurgilor „Nicolae Anestiadi” și al III-lea Congres al Societății de Endoscopie, Chirurgie miniminvazivă și Ultrasonografie ”V.M.Guțu” din Republica MoldovaIntroducere: Sindromul Boerhaave (ruptura spontană de esofag toracic) este o patologie greu de diagnosticat și cu mortalitate foarte mare în cazul lipsei tratamentului adecvat, care este chirurgical cât mai precoce. Material și metode: Prezentăm 3 pacienți bărbați, doi în vârstă de 42 ani, al treilea de 72 ani, care au fost internați pentru hematemeză, dureri violente epigastrice, retrosternale și toracice stângi, stare generală de rău, apărute după un efort de vărsătură pe fondul consumului de alcool, emfizem subcutanat cervical bilateral. Diagnosticul a fost suspicionat pe baza anamnezei, examenului clinic, colecției lichidiene pleurale stângi cu aspect tulbure maroniu (cu amilaze crescute) și mai ales radiologic, care a evidențiat pneumomediastin și nivel hidroaeric retrocardiac, confirmat de ingestia de substanță de contrast hidrosolubilă (la un caz). Toți pacienții prezentau deja semne clinice și paraclinice de sepsis, astfel încât la 14, 9, respectiv 16 ore de la momentul estimat al producerii efracției esofagiene, s-a instituit tratamentul chirurgical. Rezultate: Sub anestezie generala s-a efectuat toracotomie posterolaterală stângă cu rezecția coastei VII și prepararea unui lambou pediculat posterior de mușchi intercostal VII. S-a debridat excizional pio-pneumomediastinul și cavitatea pleurală stângă, toaletă abundentă, sutura esofagiană în dublu strat acoperită cu lamboul de mușchi intercostal, dublu drenaj pleural aspirativ, gastrostomie de decompresie și alimentație la primul caz, doar sondă nazo-gastrică – la ultimele două cazuri. Asocierea antibioticoterapiei masive, vasopresororilor și nutriției au contribuit la evoluția favorabilă (clinic și radiologic), cu închiderea gastrostomei peste trei săptămâni la primul pacient. Concluzii: Corelarea datelor anamnestice cu cele radiologice și un înalt grad de suspiciune sunt esențiale pentru stabilirea cât mai precoce a sindromului Boerhaave. În cazurile diagnosticate precoce (ideal sub 12 ore, acceptabil până la 24 ore de la momentul perforației) șansele tratamentului reparator reușit sunt maxime.Background: Boerhaave syndrome (spontaneous rupture of thoracic esophagus) is a condition difficult for diagnosis with very high mortality in the absence of adequate treatment, which is surgically as early as possible. Methods and materials: We present three male patients, two aged 42 years, the third 72 years admitted for hematemesis, epigastric, retrosternal and left thoracic pain, general malaise appeared after a vomiting effort after alcohol consumption, bilateral subcutaneous cervical emphysema. The diagnosis was suspected on the basis of history, physical examination, left pleural cloudy brown collection (with increased amylase level) and especially radiological findings, which revealed pneumomediastinum and retro-cardiac air-fluid level, confirmed by the intake of water-soluble contrast (in one case). All patients already had clinical and laboratory signs of sepsis, so surgical treatment performed at 14, 9 and 16 hours from the estimated time of esophageal rupture. Results: Under general anesthesia, left posterolateral thoracotomy with the VII rib resection and the preparation of a posterior pedicle flap of intercostal muscle were performed. Large debridement of mediastinum and left pleural cavity, abundant lavage was done. Two-plane esophageal closure covered with intercostal muscle flap, double aspiration drainage, gastrostomy for decompression and nutrition in the first case, and only nasogastric tube – in the last two cases. Association of massive antibiotic therapy, vasopressors and nutrition contributed to the favorable (clinical and radiological) outcomes, with gastrostomy closing over three weeks in the first patient. Conclusion: The correlation of anamnestic and radiological data and a high degree of suspicion are essential for establishing the Boerhaave syndrome as early as possible. In cases diagnosed early (better under 12 hours, acceptable up to 24 hours after perforation), the chances of successful reparative treatment are maximal

Field-induced criticality in a gapped quantum magnet with bond disorder

Neutron diffraction and calorimetric measurements are used to study the field-induced quantum phase transition in piperazinium-Cu$_2$(Cl$_{1-x}$Br$_x$)$_6$ ($x=0$, x=3.5% and x=7.5%), a prototypical quantum antiferromagnet with random bonds. The critical indexes $\phi$ and $\beta$ are determined. The findings contradict some original predictions for Bose Glass based on the assumption $z=d$, but are consistent with recent theoretical results implying $z<d$. Inelastic neutron experiments reveal that disorder has a profound effect on the lowest-energy magnetic gap excitation in the system.Comment: 4.2 pages, 4 figures.

Section Extension from Hyperbolic Geometry of Punctured Disk and Holomorphic Family of Flat Bundles

The construction of sections of bundles with prescribed jet values plays a fundamental role in problems of algebraic and complex geometry. When the jet values are prescribed on a positive dimensional subvariety, it is handled by theorems of Ohsawa-Takegoshi type which give extension of line bundle valued square-integrable top-degree holomorphic forms from the fiber at the origin of a family of complex manifolds over the open unit 1-disk when the curvature of the metric of line bundle is semipositive. We prove here an extension result when the curvature of the line bundle is only semipositive on each fiber with negativity on the total space assumed bounded from below and the connection of the metric locally bounded, if a square-integrable extension is known to be possible over a double point at the origin. It is a Hensel-lemma-type result analogous to Artin's application of the generalized implicit function theorem to the theory of obstruction in deformation theory. The motivation is the need in the abundance conjecture to construct pluricanonical sections from flatly twisted pluricanonical sections. We also give here a new approach to the original theorem of Ohsawa-Takegoshi by using the hyperbolic geometry of the punctured open unit 1-disk to reduce the original theorem of Ohsawa-Takegoshi to a simple application of the standard method of constructing holomorphic functions by solving the d-bar equation with cut-off functions and additional blowup weight functions

Lidar depolarization characterization using a reference system

In this study, we present a new approach for the determination of polarization parameters of the Nicosia Cimel CE376 lidar system, using the PollyXT in Limassol as a reference instrument. The method is applied retrospectively to the measurements obtained during the 2021 Cyprus Fall Campaign. Lidar depolarization measurements represent valuable information for aerosol typing and for the quantification of some specific aerosol types such as dust and volcanic ash. An accurate characterization is required for quality measurements and to remove instrumental artifacts. In this article, we use the PollyXT, a widely used depolarization lidar, as our reference to evaluate the CE376 system's gain ratio and channel cross-talk. We use observations of transported dust from desert regions for this approach, with layers in the free troposphere. Above the boundary layer and the highest terrain elevation of the region, we can expect that, for long-range transport of aerosols, local effects should not affect the aerosol mixture enough for us to expect similar depolarization properties at the two stations (separated by ∼ 60 km). Algebraic equations are used to derive polarization parameters from the comparison of the volume depolarization ratio measured by the two systems. The applied methodology offers a promising opportunity to evaluate the polarization parameters of a lidar system, in cases where a priori knowledge of the cross-talk parameters is not available, or to transfer the polarization parameters from one system to the other.</p
