Joint Time-Frequency And Wavelet Analysis - An Introduction
Authors: Majkowski Andrzej , Kołodziej Marcin , Rak Remigiusz J. 
Published: December 2014

Abstract
A traditional frequency analysis is not appropriate for observation of properties of non-stationary signals. This stems from the fact that the time resolution is not defined in the Fourier spectrum. Thus, there is a need for methods implementing joint time-frequency analysis (t/f) algorithms. Practical aspects of some representative methods of time-frequency analysis, including Short Time Fourier Transform, Gabor Transform, Wigner-Ville Transform and Cone-Shaped Transform are described in this paper. Unfortunately, there is no correlation between the width of the time-frequency window and its frequency content in the t/f analysis. This property is not valid in the case of a wavelet transform. A wavelet is a wave-like oscillation, which forms its own “wavelet window”. Compression of the wavelet narrows the window, and vice versa. Individual wavelet functions are well localized in time and simultaneously in scale (the equivalent of frequency). The wavelet analysis owes its effectiveness to the pyramid algorithm described by Mallat, which enables fast decomposition of a signal into wavelet components.

Published: December 2014

Electroneurography as one of the electrodiagnostic techniques is used to measure the speed of action potential which is propagated down the nerve after stimulation. It gives information about normal functioning of the peripheral nerves. The aim of this study was to evaluate the applicability of a new electroneurographic technique by performing motor nerve conduction velocity measurements in the ulnar nerve with surface stimulating electrodes in healthy dogs, to correlate the obtained data by age, limb length, rectal temperature, and sex; and to compare these results with published findings utilizing needle stimulating electrodes. The study was performed in 24 clinically healthy dogs without anaesthesia. Rectal temperatures and limb lengths were measured in all individuals. There were significant correlations among several indicators (age, rectal temperature, limb length, conduction velocity, latency and duration of compound muscle action potentials). Limb length was found to have a significant effect on the duration of the compound muscle action potential from both stimulation sites (proximal/distal; r = 0.71, r = 0.68, P < 0.01), but there was no effect on the conduction velocity or amplitude of the action potentials. There was no significant difference (P > 0.05) in the measured indicators between males and females, even though females had a higher mean conduction velocity than males. These results prove that conduction velocity measurements in dogs could be performed non-invasively, without a danger of infection or haematomas or complications with anaesthesia, which is more favourable and time-saving for clinical practice, and more comfortable for patients.

A influência da cultura organizacional universitária sobre o processo de transferência tecnológica
Authors: Schreiber Dusan 
Published: December 2014

O atual ritmo de desenvolvimento tecnológico obriga as empresas não apenas manter investimentos em inovação, como, também, aumentar continuamente o valor aplicado devido ao crescente custo de P&D. As instituições de ensino, por sua vez, detêm o conhecimento técnico, pessoal especializado e infra-estrutura laboratorial de alto nível, além do interesse em se aproximar das empresas, para disponibilizar os conhecimento gerados dentro de seus centros de pesquisa. Os governos, com o objetivo de fazer frente à globalização e garantir a sustentabilidade econômica das empresas nacionais, procuram, de várias formas, criar mecanismos para fomentar a consolidação do parque fabril local, com a geração de emprego e renda. Desta convergência de motivos, finalidades e necessidades dos três atores, empresas instituições de ensino e governo, surgiu a configuração de um novo modelo de desenvolvimento tecnológico denominado de "Hélice Tripla" onde os governos criam os fundos com recursos financeiros que são liberados para o desenvolvimento de projetos e inovações, condicionandos à sua aplicação em projetos executados em conjunto com as instituições de ensino/ pesquisa e empresas. A presente pesquisa tem por objetivo evidenciar o grau de influência da cultura organizacional de um grupo específico de profissionais, constituído de pesquisadores e docentes de uma universidade privada de grande porte, na região sul do país, no processo de transferência tencológica.
Documenting Diaspora: Multiperspectivity in Sandhya Suri's Auto/Biographical Film "I for India"
Authors: Linke Gabriele M. 
Published: December 2014

Yash Pal Suri, a young Indian doctor, went to the UK in 1965 to complete his medical training. He equipped himself and his family back in India with a camera, tape recorder etc. so that they could film episodes of their lives and exchange 'cine-letters,' which they did for about 40 years. In 2005, Suri's daughter, Sandhya Suri, created a 70-minute documentary from her family's filmed stories and other sources, selecting and arranging the various scenes and voices recorded and combining them with clips from historical TV programmes as well as interviews and short scenes filmed between 2003 and 2005 in India and England. She re-constructs her transnational family's life story as embedded it in a complex set of factors and influences. Sandhya' documentary is, on various levels, both biographical (hers of her family, and family members talking about each other) and autobiographical (her presence in the film and family members talking about themselves), and these perspectives are deeply entangled. By emphasising her family's failed attempt to re-settle in India, she complicates the story of cultural integration. The result is a reconstruction of this diasporic life narrative from various angles and along the various axes of diasporic relations, especially those with home (India) and the host society, describing the position of the diasporic subject as in-between and continuously shifting.

Communicative Identity in the Eighteenth Century; Johann Wilhelm Ludwig Gleim's Epistolary Network and the Cult of Friendship
Authors: Heinrich Tobias 
Published: December 2014

In recent years the field of ‘life writing’ has been shaped by critical approaches that have abandoned traditional notions of the singular, self-governing individual in favor of a multiple and processual concept of the subject which understands the self as socially determined. A key role is played by an engagement with the technological and medial requirements – the material basis – of the subject’s construction. In contributing to this debate, this article looks at a configuration that, while it has numerous structural analogies to the present, is historically situated in the eighteenth century. Using the example of the epistolary network around the German Enlightenment figure Johann Wilhelm Ludwig Gleim (1719–1803), I will argue that at one of the decisive turning points in the formation of the modern concept of the subject there was a form of medial communication which stood at odds to the idea of a unified and autonomous self. Through the relationship created between author and addressee, the letter constructed changing versions of the self that made the success of communication dependent on the play between textual ambiguities and the imagination. At the same time the article examines the role of the visual image as a substitute for the other in epistolary communication. Under the guiding concept of ‘friendship’ a network of text and identity production occurring in parallel is formed. Such a network is not solely based on the principle of individual autonomy but also on collective recognition. This article was submitted on July 1st 2014 and published on December 5th 2014.
Synthesis, Crystal Structures, and Thermal and Spectroscopic Properties of Thiocyanato Coordination Compounds with 3-Acetylpyridine as a Ligand
Authors: Werner Julia , Jeß Inke , Näther Christian 
Published: December 2014

Abstract
The reaction of transition metal thiocyanates with 3-acetylpyridine (3-Acpy) leads to the formation of compounds of compositions M(NCS)2(3-Acpy)4 (M1; M = Mn, Fe, Ni) and M(NCS)2(3- Acpy)2(H2O)2 (M2; M = Mn, Fe, Ni). Thermogravimetric investigations show that in the first step some of these compounds transform into the new coordination polymers M(NCS)2(3-Acpy)2 (M3 with M = Mn, Fe and Ni), that decompose into the new compounds M(NCS)2(3-Acpy) (M4 with M = Mn and Ni) in the second step. Unfortunately, the powder patterns of compounds M3 and M4 cannot be indexed, and there are strong indications that these compounds are contaminated with a small amount of the precursor or unknown crystalline phases. IR spectroscopic investigations indicate that in compounds M3 the metal cations are linked by μ-1,3-bridging thiocyanato anions into 1D or 2D coordination polymers that are further linked by the 3-Acpy ligands in compounds M4.
Die Strukturchemie der 2-Chalkogeno-1,3,4,5-tetraisopropylimidazoline / The Structural Chemistry of the 2-Chalcogeno-1,3,4,5-tetraisopropylimidazolines

Published: December 2014

Abstract
1,3,4,5-Tetraisopropyl-2-thioimidazoline (6b) was prepared by condensation of N,N′-diisopropylthiourea and isobutyroin. 1,3,4,5-Tetraisopropyl-2-oxoimidazoline (6a), 1,3,4,5-tetraisopropyl-2- selenoimidazoline (6c) and 1,3,4,5-tetraisopropyl-2-telluroimidazoline (6d) were obtained from 2,3- dihydro-1,3,4,5-tetraisopropylimidazol-2-ylidene and dinitrogen oxide or selenium and tellurium, respectively. The crystal structure analyses revealed the presence of the A-type rotamer for 6a while for 6c a paddlewheel-like orientation of the isopropyl substituents was found (I type). In crystals of 6b, both A- and E-type molecules are present while in solution at room temperature the I-type rotamer is detected. A dynamic 1H and 13C{1H} NMR study of 6b in the range of 185.5 to 423.3K revealed a temperature-dependent rotation of the isopropyl substituents (ΔH‡ = 15:7(9) kcal mol-1, ΔS‡ = -5(3) calK-1 mol-1, ΔG‡ = 17:2(9) kcal mol-1) with I as the rotamer of lowest energy. This result is confirmed by MO calculations which indicate A and C being the next stable rotamers. The barrier of rotation of the isopropyl substituents about the C-N bond from I to C (B3LYP ΔH‡ =13:7 kcal mol-1,ΔG‡ =15:4 kcal mol-1) is slightly lower than that about the C-C bond from I to G.

Published: December 2014

Abstract
The RSCH2CH2B(C6F5)2 boranes 3a (R=Ph) and 3b (R=Et) were in situ generated by HB(C6F5)2 hydroboration of the respective vinylthioethers. Their treatment with R1-C≡C- SiMe3 acetylenes resulted in clean 1,1-carboboration to give the respective RSCH2CH2-substituted alkenylboranes 4 (3 examples). Likewise, the reagents 3 underwent 1,1-carboboration with the acetylenes Ar2P-C≡C-SiMe3 to give the tetrasubstituted alkenylboranes 6, featuring a geminal pair of RSCH2CH2=B(C6F5)2 substituents at one carbon atom and the Me3Si=PAr2 pair at the other (3 examples). The compounds 6 feature an internal B···P interaction. The conceptually related Mes2PCH2CH2B(C6F5)2 borane (2) does not undergo 1,1-carboboration with ArS-C≡C-SiMe3 but forms the 1,2-P=B-FLP addition product 7 to the acetylene instead. Compounds 4a, 4c, 6a, and 7 were characterized by X-ray diffraction.

Published: December 2014

Abstract
Massive inguinoscrotal hernias extending below the midpoint of the inner thigh, in the standing position constitute giant inguinoscrotal hernias. We report a patient who presented with giant right inguinal hernia with bilateral hydrocele for 25 years. He had no cardiorespiratory illnesses. He was taken up for surgery under general anesthesia after preoperative respiratory exercises. Sliding hernia with entire greater omentum, small bowel, and appendix as contents was identified. Meshplasty after omentectomy with bilateral subtotal excision of sac, right orchidectomy, and scrotoplasty were done. Giant inguinoscrotal hernias pose significant problems while replacing bowel contents because of the increase in intraabdominal and intrathoracic pressures. Recurrence is another complication seen after successful surgical management. Various techniques such as preoperative pneumoperitoneum, debulking abdominal contents with extensive bowel resections, or omentectomy and phrenectomy have been tried. Postoperative elective ventilation is also needed in many cases. We describe simple reduction with omentectomy as a viable technique in this patient. He did not need elective ventilation due to preoperative respiratory exercises and preparation and review of the literature.

Abstract
We present a case undergoing successful laparoscopic ligation of the inferior mesenteric artery (IMA) and internal iliac artery (IIA) for the treatment of a symptomatic type II endoleak (T2E) after endovascular aneurysm repair (EVAR). The patient presented with abdominal and back pain 1 year after EVAR. Subsequent enhanced computed tomography scan showed aneurysm sac enlargement from 60 mm to 70 mm, and digital substraction angiography revealed a T2E caused by patent IMA and right IIA. Then the patient underwent successful laparoscopic ligation of the IMA and right IIA. Postprocedural angiogram demonstrated complete resolution of the type II endoleak, and no intraoperative complications occurred. Also, there was no remaining abdominal pain or back pain after the operation.
Effect of the local clay distribution on the effective electrical conductivity of clay rocks
Authors: Cosenza P. , Prêt D. , Zamora M. 
Published: December 2014

AbstractThe “local porosity theory” proposed by Hilfer was revisited to develop a “local clay theory” (LCT) that establishes a quantitative relationship between the effective electrical conductivity and clay distribution in clay rocks. This theory is primarily based on a “local simplicity” assumption; under this assumption, the complexity of spatial clay distribution can be captured by two local functions, namely, the local clay distribution and the local percolation probability, which are calculated from a partitioning of a mineral map. The local clay distribution provides information about spatial clay fluctuations, and the local percolation probability describes the spatial fluctuations in the clay connectivity. This LCT was applied to (a) a mineral map made from a Callovo‐Oxfordian mudstone sample and (b) (macroscopic) electrical conductivity measurements performed on the same sample. The direct and inverse modeling shows two results. First, the textural and classical model assuming that the electrical anisotropy of clay rock is mainly controlled by the anisotropy of the sole clay matrix provides inconsistent inverted values. Another textural effect, the anisotropy induced by elongated and oriented nonclayey grains, should be considered. Second, the effective conductivity values depend primarily on the choice of the inclusion‐based models used in the LCT. The impact of local fluctuations of clay content and connectivity on the calculated effective conductivity is lower.

AbstractBackgroundClinicians often encounter left pleural effusion after esophagectomy, which sometimes necessitates thoracentesis. We have introduced a new drainage method, bilateral pleural drainage by single Blake drain (BDSD), which we have been using since April 2013. This study aims to evaluate the performance of the BDSD.MethodsThe BDSD method employs a 15‐F Blake drain inserted from the right thoracic cavity to the left thoracic cavity across the posterior mediastinum. The conventional drain (CD) group consisted of 50 patients with a 19‐F Blake drain placed in the right thoracic cavity during the period from April 2012 to March 2013. The BDSD group consisted of 54 patients treated from April 2013 to June 2014.ResultsThe amount of total drainage in the BDSD group was significantly higher than that in the CD group (P < 0.0001). The rates of left pleural effusion and left lower lobe atelectasis in the BDSD group were significantly lower than those in the CD group (P < 0.0001 and P < 0.0001, respectively). No patients developed a left pleural effusion necessitating thoracentesis drainage in the BDSD group.ConclusionsCompared with the conventional method, BDSD was able to evacuate bilateral pleural effusion more effectively, and the incidences of left pleural effusion and left atelectasis were lower. This method is therefore clinically useful after esophagectomy.
Preparation and characterization of regenerated MgO-CaO refractory bricks sintered under different atmospheres

Published: December 2014

Abstract
Regenerated MgO-CaO brick samples containing 80wt%, 70wt%, and 60wt% MgO were prepared using spent MgO-CaO bricks and fused magnesia as raw materials and paraffin as a binder. The bricks were sintered at 1873 K for 2 h under an air atmosphere and under an isolating system. The microstructure, mechanical properties at room temperature, and hydration resistance of the regenerated samples were measured and compared. The results indicated that the isolating sintering generated a strongly reducing atmosphere as a result of the incomplete combustion of paraffin, and the partial oxygen pressure was approximately 6.68 × 10−7 Pa. The properties of the regenerated bricks sintered under air conditions were all higher than those of the bricks sintered under a reducing atmosphere. The deterioration of the bricks was a result of MgO reduction and a decrease in the amount of liquid phase formed during sintering under a reducing atmosphere.
Primary care-led commissioning and public involvement in the English National Health Service. Lessons from the past
Authors: Petsoulas Christina , Peckham Stephen , Smiddy Jane , Wilson Patricia 
Published: December 2014

BackgroundPatient and Public involvement (PPI) in health care occupies a central place in Western democracies. In England, this theme has been continuously prominent since the introduction of market reforms in the early 1990s. The health care reforms implemented by the current Coalition Government are making primary care practitioners the main commissioners of health care services in the National Health Service, and a duty is placed on them to involve the public in commissioning decisions and strategies. Since implementation of PPI initiatives in primary care commissioning is not new, we asked how likely it is that the new reforms will make a difference. We scanned the main literature related to primary care-led commissioning and found little evidence of effective PPI thus far. We suggest that unless the scope and intended objectives of PPI are clarified and appropriate resources are devoted to it, PPI will continue to remain empty rhetoric and box ticking.AimTo examine the effect of previous PPI initiatives on health care commissioning and draw lessons for future development.MethodWe scanned the literature reporting on previous PPI initiatives in primary care-led commissioning since the introduction of the internal market in 1991. In particular, we looked for specific contexts, methods and outcomes of such initiatives.Findings1. PPI in commissioning has been constantly encouraged by policy makers in England. 2. Research shows limited evidence of effective methods and outcomes so far. 3. Constant reconfiguration of health care structures has had a negative impact on PPI. 4. The new structures look hardly better poised to bring about effective public and patient involvement.

Focus Sensitive Operators
Authors: Beck Sigrid 
Published: December 2014

AbstractThis chapter investigates operators that evaluate alternatives. An indirect analysis of association with focus (Rooth (1992) is assumed, according to which there is just one focus evaluating operator. In addition to focus, questions and polarity items are considered. Both also involve an operator that evaluates alternatives. The alternative semantic tier is thus used in several types of construction, and the interaction of the respective operators has to be investigated. A compositional semantic analysis of alternatives is argued for that is based on distinguished variables.
