Path Integral Quantization of the Symplectic Leaves of the SU(2)* Poisson-Lie Group

The Feynman path integral is used to quantize the symplectic leaves of the Poisson-Lie group SU(2)*. In this way we obtain the unitary representations of U_q(su(2)). This is achieved by finding explicit Darboux coordinates and then using a phase space path integral. I discuss the *-structure of SU(2)* and give a detailed description of its leaves using various parametrizations and also compare the results with the path integral quantization of spin.Comment: 24 pages, LaTeX, no figures, full postscript available from http://phyweb.lbl.gov/theorygroup/papers/40890.p

A Variational Formulation of Symplectic Noncommutative Mechanics

The standard lore in noncommutative physics is the use of first order variational description of a dynamical system to probe the space noncommutativity and its consequences in the dynamics in phase space. As the ultimate goal is to understand the inherent space noncommutativity we propose a variational principle for noncommutative dynamical systems in configuration space, based on results of our previous work [14]. We hope that this variational formulation in configuration space can be of help to elucidate the definition of some global and dynamical properties of classical and quantum noncommutative space.Comment: 17 pages, Latex.

Dupilumab ocular side effects in patients with atopic dermatitis: a systematic review

Atopic dermatitis (AD) is a chronic, inflammatory skin disorder that most frequently occurs in children, but it can also affect adults. Even though most AD cases can be managed with topical treatments, moderate-to-severe forms require systemic therapies. Dupilumab is the first human monoclonal antibody approved for the treatment of AD. Its action is through IL-4 receptor alpha subunit inhibition, thus blocking IL-4 and IL-13 signaling pathways. It has been shown to be an effective, well-tolerated therapy for AD, as well as for asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), and eosinophilic esophagitis (EoE). However, an increasing incidence of dupilumab-induced ocular surface disease (DIOSD) has been reported in patients treated with dupilumab, as compared to placebo. The aim of this study was to summarize scientific data regarding DIOSD in AD patients treated with dupilumab. A search of PubMed and clinicaltrials.gov databases was performed. There was no limit to study design. All AD cases were moderate-to-severe. DIOSD was either dermatologist-, allergist-, or ophthalmologist-assessed. Evidence shows that DIOSD occurs most frequently in patients with atopic dermatitis and not in other skin conditions, neither in patients with asthma, CRSwNP, nor EoE who are on dupilumab treatment. Further studies are warranted in order to establish a causal relationship between dupilumab and ocular surface disease. Nevertheless, ophthalmological evaluations prior to dupilumab initiation can benefit AD patients with previous ocular pathology or current ocular symptomatology. Also, patch testing for ocular allergic contact dermatitis might be advantageous in patients with a history of allergic conjunctivitis. Furthermore, TARC, IgE, and circulating eosinophils levels might be important biomarkers for a baseline assessment of future candidates to dupilumab treatment. However, TARC measurements should be resumed for research purposes only

Design and Implementation of a Distributed Platform for Sharing IP Flow Records

Experiments using real traffic traces are of key importance in many network management research fields, such as traffic characterization, intrusion detection, and accounting. Access to such traces is often restricted due to privacy issues; research institutions typically have to sign non-disclosure agreements before accessing such traces from a network operator. Having such restrictions, researchers rarely have more than one source of traffic traces on which to run and validate their experiments. Therefore, this paper develops a Distributed Platform for Sharing IP Flows (DipSIF) based on NetFlow records between multiple institutions. It is assumed that NetFlow traces collected by each participant are archived on separate storage hosts within their premises and then made available to others using a server that acts as a gateway to the storage. Due to privacy reasons the platform presented here uses a prefix-preserving, cryptography-based, and consistent anonymization algorithm in order to comply to different regulations determining the exchange of traffic traces data

Intractable Hiccups and a Posterior Fossa Arteriovenous Malformation: A Case Report

A 29-year-old man is presented who developed intractable hiccups following a subarachnoid hemorrhage from a posterior fossa dural arteriovenous malformation (AVM). The hiccups persisted even after various treatments had been attempted, and the AVM had been excised surgically. The hiccups stopped after a bilateral phrenic nerve section was performed. This report reviews the central causes and mechanisms of hiccups and emphasizes the importance of selective vertebral angiography in demonstrating posterior fossa AVM

Bioeconomic solutions for preserving the local breeds in the Banat euroregion

This paper is based on previous studies which are dedicated to the inovativ concept of bio-economic solutions derived from ethnozootechny and associated to climate change which have an impact upon the domestic animals’ resistance and production. The descriptive study presents the reasons and the challenges for which the local breeds must be preserved; for the first time, rusticity is approached differently, being no wone of the desirable features which has never been approached in animal selection in Romania. The arguments of the paper plead for maintaining the local breeds – this proves the cultural intelligence of the communities that created them. The products obtained from these animals are the base of the ethnogastronomy of various ethnies in Transylvania and Banat and can contribute to a raise in economic competitiveness, becoming an added value in this niche market and having immediate socio-bio-economic effects: a high level of occupancy in the labour force, diminishing the rural poverty and a certain bioeconomic independency in certain conditions. This study claims that in the strategy for bio-economic development of Banat and Transylvania in 2016-2030 there should be taken into consideration the results of the ethno – animal husbandry research as a part of the territorial capital

Constant magnetic field and 2d non-commutative inverted oscillator

We consider a two-dimensional non-commutative inverted oscillator in the presence of a constant magnetic field, coupled to the system in a ``symplectic'' and ``Poisson'' way. We show that it has a discrete energy spectrum for some value of the magnetic field.Comment: 7 pages, LaTeX file, no figures, PACS number: 03.65.-
