Authors: Purohit S. D. , Raina R. K. 
Published: November 2014

Abstract
By applying the q-derivative operator of order m (m ∈ ℕ0), we introduce two new subclasses of p-valently analytic functions of complex order. For these classes of functions, we obtain the coefficient inequalities and distortion properties. Some consequences of the main results are also considered
Face Recognition Based on Wavelet Kernel Non-Negative Matrix Factorization
Authors: Bai, Lin , Li Yanbo , Hui Meng 
Published: November 2014

Abstract
In this paper a novel face recognition algorithm, based on wavelet kernel non-negative matrix factorization (WKNMF), is proposed. By utilizing features from multi-resolution analysis, the nonlinear mapping capability of kernel nonnegative matrix factorization could be improved by the method proposed. The proposed face recognition method combines wavelet kernel non-negative matrix factorization and RBF network. Extensive experimental results on ORL and YALE face database show that the suggested method possesses much stronger analysis capability than the comparative methods. Compared with PCA, non-negative matrix factorization, kernel PCA and independent component analysis, the proposed face recognition method with WKNMF and RBF achieves over 10 % improvement in recognition accuracy.

Abstract
GaInNAs alloys are mostly used as an active part of light sources for long wavelength telecom applications. Beside this, these materials are used as thin quantum wells (QWs), and a need is to grow thick layers of such semiconductor alloys for photodetectors and photovoltaic cells applications. However, structural characterization of the GaInNAs layers is hindered by non-homogeneity of the In and N distributions along the layer. In this work the challenges of the structural characterization of doped thick GaInNAs layers grown by atmospheric pressure metalorganic vapour phase epitaxy (APMOVPE) will be presented
Diagnostics of DC and Induction Motors Based on the Analysis of Acoustic Signals
Authors: Glowacz A. 
Published: November 2014

Abstract
In this paper, a non-invasive method of early fault diagnostics of electric motors was proposed. This method uses acoustic signals generated by electric motors. Essential features were extracted from acoustic signals of motors. A plan of study of acoustic signals of electric motors was proposed. Researches were carried out for faultless induction motor, induction motor with one faulty rotor bar, induction motor with two faulty rotor bars and flawless Direct Current, and Direct Current motor with shorted rotor coils. Researches were carried out for methods of signal processing: log area ratio coefficients, Multiple signal classification, Nearest Neighbor classifier and the Bayes classifier. A pattern creation process was carried out using 40 samples of sound. In the identification process 130 five-second test samples were used. The proposed approach will also reduce the costs of maintenance and the number of faulty motors in the industry.

Authors: Tabakovic Slobodan , Zeljkovic Milan , Milojevic Zoran 
Published: November 2014

Abstract
The success of the hip arthroplasty surgery largely depends on the endoprosthesis adjustment to the patient's femur. This implies that the position of the femoral bone in relation to the pelvis is preserved and that the endoprosthesis position ensures its longevity. Dimensions and body shape of the hip joint endoprosthesis and its position after the surgery depend on a number of geometrical parameters of the patient's femur. One of the most suitable methods for determination of these parameters involves 3D reconstruction of femur, based on diagnostic images, and subsequent determination of the required geometric parameters. In this paper, software for automated determination of geometric parameters of the femur is presented. Detailed software development procedure for the purpose of faster and more efficient design of the hip endoprosthesis that ensures patients’ specific requirements is also offered

Abstract
Polyester fabric was treated with polyvinyl alcohol in alkaline medium. The moisture regain, water retention and wettability of the PVA treated polyester fabric were tested. The PVA treated PET fabric was dyed with disperse dye. The presence of PVA in the treated PET fabric was assessed by spot test. The treated fabric was also characterized by scanning electron microscope, FTIR and differential scanning calorimetry. The PVA treated polyester fabric showed improved hydrophilic character over intact and sodium hydroxide treated PET fabrics.
Analysis of the Skpos® users Initialisation Times
Authors: Droščák Branislav , Smolík Karol 
Published: November 2014

Abstract
From the establishment of the Slovak real time positioning service (SKPOS®), the reference stations’ observations, network solutions and outputs from the user communications with the service control software were set for archiving. Today we know that all those archived data have the potential to give us valuable information about the service’s character and quality and about the conditions during the performance of Real time Kinematic (RTK) measurements. After conducting some analyses, we are able to easily understand how important factors such as the number of satellites used, the state of the ionosphere, network solutions in the border zone, densification of the network, etc., can affect those measurements. For those purposes the users’ initialisation times derived from the archived National Marine Electronics Association (NMEA) messages are used in advance. As a tool for analysis the new Application for SKPOS® Monitoring and R
Living or Dead? Specifics of the Language of the Second Amendment to the U.S. Constitution
Authors: Kraśnicka Izabela 
Published: November 2014

Abstract
The original text of the Constitution of the United States of America, written over 200 years ago, constitutes the supreme source of law in the American legal system. The seven articles and twenty seven amendments dictate understanding of fundamental principles of the federation’s functioning and its citizens’ rights.
The paper aims to present the evolution of the U.S. Constitution’s language interpretation as provided by its final interpreter - the Supreme Court of the United States. Example of the Second Amendment will be analyzed to present the change in understanding of the language grammar and, as a consequence, the sense of the right to keep and bear arms in the light of the Supreme Court’s decision in the case of District of Columbia v Heller (554 U.S. 570 (2008)).
It will argue for the accuracy of statement of Charles Evans Hughes, former Chief Justice of the U.S. Supreme Court: “We are under a Constitution, but the Constitution is what the judges say it is...”
In Quest of Sufficient Equivalence. Polish and English Insolvency Terminology in Translation. a Comparative Study
Authors: Matulewska Aleksandra 
Published: November 2014

Abstract
The paper deals with the problem of translating selected insolvency terminology from Polish into English and from English into Polish. The re- search corpora encompassed the Insolvency Act 1986 (England and Wales) as amended and Ustawa z dnia 28 lutego 2003. Prawo upadłościowe i naprawcze [the Act on Polish Insolvency and Rehabilitation Law of 28th February 2003 as amended]. The research methods included: (i) the comparison of parallel texts, (ii) the method of axiomatisation of the legal linguistic reality, (iii) the termino- logical analysis of the corpus material, (iv) the concept of adjusting the target text to the communicative needs and requirements of the community of recipients and (v) the techniques of providing equivalents for non-equivalent terminology. The research hypothesis has been so formulated that the parametrisation of legal reality may assist in finding more adequate equivalents and determine differences in meaning of compared source and target language terms, which in turn facilitates the choice of a more adequate technique of providing equivalents for non-equivalent or partially equivalent legal terminology meeting the com- municative needs of translation recipients. The research results revealed that insolvency terminology is highly system-bound and available equivalents may often be misleading for the community of target text recipients

Object
To date, health care providers have devoted significant efforts to improve performance regarding patient safety and quality of care. To address the lagging involvement of health care providers in the cost component of the value equation, UCLA Health piloted the implementation of time-driven activity-based costing (TDABC). Here, the authors describe the implementation experiment, share lessons learned across the care continuum, and report how TDABC has actively engaged health care providers in costing activities and care redesign.

Methods
After the selection of pilots in neurosurgery and urology and the creation of the TDABC team, multidisciplinary process mapping sessions, capacity-cost calculations, and model integration were coordinated and offered to engage care providers at each phase.

Results
Reviewing the maps for the entire episode of care, varying types of personnel involved in the delivery of care were noted: 63 for the neurosurgery pilot and 61 for the urology pilot. The average cost capacities for care coordinators, nurses, residents, and faculty were $0.70 (range $0.63–$0.75), $1.55 (range $1.28–$2.04), $0.58 (range $0.56–$0.62), and $3.54 (range $2.29–$4.52), across both pilots. After calculating the costs for material, equipment, and space, the TDABC model enabled the linking of a specific step of the care cycle (who performed the step and its duration) and its associated costs. Both pilots identified important opportunities to redesign care delivery in a costconscious fashion.

Conclusions
The experimentation and implementation phases of the TDABC model have succeeded in engaging health care providers in process assessment and costing activities. The TDABC model proved to be a catalyzing agent for cost-conscious care redesign.
A comparison of lumboperitoneal and ventriculoperitoneal shunting for idiopathic intracranial hypertension: an analysis of economic impact and complications using the Nationwide Inpatient Sample
Authors: Menger Richard P. , Connor David E. , Thakur Jai Deep , Sonig Ashish , Smith Elainea , Guthikonda Bharat , Nanda Anil 
Published: November 2014

Object
Complications following lumboperitoneal (LP) shunting have been reported in 18% to 85% of cases. The need for multiple revision surgeries, development of iatrogenic Chiari malformation, and frequent wound complications have prompted many to abandon this procedure altogether for the treatment of idiopathic benign intracranial hypertension (pseudotumor cerebri), in favor of ventriculoperitoneal (VP) shunting. A direct comparison of the complication rates and health care charges between first-choice LP versus VP shunting is presented.

Methods
The Nationwide Inpatient Sample database was queried for all patients with the diagnosis of benign intracranial hypertension (International Classification of Diseases, Ninth Revision, code 348.2) from 2005 to 2009. These data were stratified by operative intervention, with demographic and hospitalization charge data generated for each.

Results
A weighted sample of 4480 patients was identified as having the diagnosis of idiopathic intracranial hypertension (IIH), with 2505 undergoing first-time VP shunt placement and 1754 undergoing initial LP shunt placement. Revision surgery occurred in 3.9% of admissions (n = 98) for VP shunts and in 7.0% of admissions (n = 123) for LP shunts (p < 0.0001). Ventriculoperitoneal shunts were placed at teaching institutions in 83.8% of cases, compared with only 77.3% of first-time LP shunts (p < 0.0001). Mean hospital length of stay (LOS) significantly differed between primary VP (3 days) and primary LP shunt procedures (4 days, p < 0.0001). The summed charges for the revisions of 92 VP shunts ($3,453,956) and those of the 6 VP shunt removals ($272,484) totaled $3,726,352 over 5 years for the study population. The summed charges for revision of 70 LP shunts ($2,229,430) and those of the 53 LP shunt removals ($3,125,569) totaled $5,408,679 over 5 years for the study population.

Conclusions
The presented results appear to call into question the selection of LP shunt placement as primary treatment for IIH, as this procedure is associated with a significantly greater likelihood of need for shunt revision, increased LOS, and greater overall charges to the health care system.

Cerebrospinal fluid–diverting shunts are often complicated by bacterial infections. Dental procedures are known to cause transient bacteremia that could potentially spread hematogenously to these implanted devices. No literature currently exists to inform practitioners as to the need for prophylactic antibiotics for patients who possess these implants. The authors performed a retrospective study to assess whether dental procedures and poor oral health were associated with a higher likelihood of developing CSF-diverting shunt infections.

Methods
Neurosurgical and pediatric dental records from January 2007 to December 2012 were reviewed for shunt surgeries and dental encounters. Indications for shunt surgery and infection rates were recorded. Dental records were reviewed for several markers of overall dental health, such as a DMFT (decayed, missing, and filled teeth) score and a gingival health/oral hygiene score. The association between these scores and the incidence of shunt infections were studied. Moreover, the relationship between the incidence of shunt infections and the timing and invasiveness of preceding dental encounters were analyzed.

Results
A total of 100 pediatric patients were included in our study, for a total of 204 shunt surgeries. Twenty-one shunt infections were noted during the 6-year study period. Five of these shunts infections occurred within 3 months of a dental procedure. The odds ratio (OR) of developing a shunt infection within 3 months of a dental procedure was 0.98 (95% confidence interval [CI] 0.27–3.01), and was not statistically significant. The OR of developing a shunt infection after a high-risk dental procedure compared with a low-risk dental procedure was 1.32 (95% CI 0.02–16.29), and was not statistically significant. There was no significant association between measures of dental health, such as DMFT and gingival health score, and the likelihood of developing a shunt infection. The ORs for these 2 scores were 0.51 (95% CI 0.04–4.96) and 1.58 (95% CI 0.03–20.06), respectively. The study was limited by sample size.

Conclusions
Dental health status and the number and type of dental procedures performed do not appear to confer a higher risk of developing a CSF-diverting shunt infection in this pediatric population.
Pelvic pain from a giant presacral Tarlov cyst successfully obliterated using aneurysm clips in a patient with Marfan syndrome

Published: November 2014

Patients with Marfan syndrome used to succumb early in life from cardiovascular complications. With the current rapid advance in medical and surgical care, such patients may now have near-normal longevities. Consequently, rare late-life complications are emerging in these patients and represent challenges to clinicians for their diagnoses and treatments. The authors report a rare case of pelvic pain and genital prolapse from a giant presacral Tarlov cyst in a 67-year-old patient with Marfan syndrome.
This 67-year-old Caucasian female presented with progressively severe pelvic pain, intermittent explosive diarrhea, and dysuria. Physical and bimanual examination demonstrated genital prolapse and a nontender, cyst-like mass fixed in the midline. She underwent ultrasound, CT, and eventually MRI evaluations that led to the diagnosis of a giant (6.7 × 6.4 × 6.6 cm) Tarlov cyst originating from the right S-2 nerve root sleeve/sacral foramen with intrapelvic extension. She underwent S1–S2 and S2–S3 laminectomy with obliteration of the Tarlov cyst using aneurysm clips. Postoperatively, her pelvic pain and bowel symptoms resolved and the bladder symptoms improved. The 3-month follow-up CT of abdomen/pelvis demonstrated resolution of the cyst.
The present case illustrates that clinicians caring for elderly patients with Marfan syndrome need to increasingly recognize such unusual late-life complications. Also, these large Tarlov cysts can be simply and effectively obliterated with aneurysm clips.
Alnus subgenus Alnus in the Eocene of western North America based on leaves, associated catkins, pollen, and fruits
Authors: Liu Xiaoyan , Manchester Steven R. , Jin Jianhua 
Published: November 2014

• Premise of the study: The fossil record of alder (Alnus) is well known in the Cenozoic deposits throughout the northern hemisphere, based on numerous reports of the distinctive pollen, cone‐like infructescences, staminate inflorescences, and leaves. However, our understanding of the systematic position of these fossils relative to the modern phylogeny of the genus has been limited because most fossils were described from only one organ.• Methods: We examined well‐preserved leaves and associated fruiting and staminate catkins from the middle Eocene, Clarno Formation, Oregon, USA by stereomicroscopy. In situ and dispersed pollen were cleaned with HF and acetolized for light and scanning electron microscopy.• Key results: We reconstructed a new extinct species based on multiple organs and discuss significant phytogeographic and phylogenetic implications for Alnus. Alnus clarnoensis sp. nov. is described based on serrate leaves with 1–4 small teeth between each primary tooth, associated cone‐like fruiting catkins with fruits in situ, and associated slender pollen catkins bearing in situ 3‐ to 6‐pored pollen with arci between the pores. Combined investigations of each organ indicate that they probably derive from the same species and can be confidently attributed to subgenus Alnus Furlow based on leaf architecture and pollen pore number frequency.• Conclusions: The Clarno fossils are most similar to the extant North American species of subgenus Alnus rather than to those from Asia and Europe, indicating that this modern subgenus was already distinct by the middle Eocene and that the intercontinental migration likely occurred earlier.
Morphometrics of Daucus (Apiaceae): A counterpart to a phylogenomic study
Authors: Arbizu Carlos , Reitsma Kathleen R. , Simon Philipp W. , Spooner David M. 
Published: November 2014

• Premise of study: Molecular phylogenetics of genome‐scale data sets (phylogenomics) often produces phylogenetic trees with unprecedented resolution. A companion phylogenomics analysis of Daucus using 94 conserved nuclear orthologs supported many of the traditional species but showed unexpected results that require morphological analyses to help interpret them in a practical taxonomic context.• Methods: We evaluated character state distributions, stepwise discriminant analyses, canonical variate analyses, and hierarchical cluster analyses from 40 morphological characters from 81 accessions of 14 taxa of Daucus and eight species in related genera in an experimental plot.• Key results: Most characters showed tremendous variation with character state overlap across many taxa. Multivariate analyses separated the outgroup taxa easily from the Daucus ingroup. Concordant with molecular analyses, most species form phenetic groups, except the same taxa that are problematical in the molecular results: (1) the subspecies of D. carota, (2) D. sahariensis and D. syrticus, and (3) D. broteri and D. guttatus.• Conclusions: Phenetic analyses, in combination with molecular data, support many Daucus species, but mostly by overlapping ranges of size and meristic variation. The subspecies of D. carota are poorly separated morphologically, are paraphyletic, and all could be recognized at the subspecies rank under D. carota. Daucus sahariensis and D. syrticus are so similar morphologically that they could be placed in synonymy. Combined molecular and morphological data support three species in accessions previously identified as D. broteri and D. guttatus. Molecular and morphological results support the new combination Daucus carota subsp. capillifolius.
Chloroplast DNA sequence utility for the lowest phylogenetic and phylogeographic inferences in angiosperms: The tortoise and the hare IV
Authors: Shaw Joey , Shafer Hayden L. , Leonard O. Rayne , Kovach Margaret J. , Schorr Mark , Morris Ashley B. 
Published: November 2014

• Premise of the study: Noncoding chloroplast DNA (NC‐cpDNA) sequences are the staple data source of low‐level phylogeographic and phylogenetic studies of angiosperms. We followed up on previous papers (tortoise and hare II and III) that sought to identify the most consistently variable regions of NC‐cpDNA. We used an exhaustive literature review and newly available whole plastome data to assess applicability of previous conclusions at low taxonomic levels.• Methods: We aligned complete plastomes of 25 species pairs from across angiosperms, comparing the number of genetic differences found in 107 NC‐cpDNA regions and matK. We surveyed Web of Science for the plant phylogeographic literature between 2007 and 2013 to assess how NC‐cpDNA has been used at the intraspecific level.• Key results: Several regions are consistently the most variable across angiosperm lineages: ndhF‐rpl32, rpl32‐trnL(UAG), ndhC‐trnV(UAC), 5′rps16‐trnQ(UUG), psbE‐petL, trnT(GGU)‐psbD, petA‐psbJ, and rpl16 intron. However, there is no universally best region. The average number of regions applied to low‐level studies is ∼2.5, which may be too little to access the full discriminating power of this genome.• Conclusions: Plastome sequences have been used successfully at lower and lower taxonomic levels. Our findings corroborate earlier works, suggesting that there are regions that are most likely to be the most variable. However, while NC‐cpDNA sequences are commonly used in plant phylogeographic studies, few of the most variable regions are applied in that context. Furthermore, it appears that in most studies too few NC‐cpDNAs are used to access the discriminating power of the cpDNA genome.
