Classifying Galois groups of small iterates via rational points
Authors: Hindes Wade
Published: December 2017

We establish several surjectivity theorems regarding the Galois groups of small iterates of [Formula: see text] for [Formula: see text]. To do this, we use explicit techniques from the theory of rational points on curves, including the method of Chabauty–Coleman and the Mordell–Weil sieve. For example, we succeed in finding all rational points on a hyperelliptic curve of genus 7, with rank 5 Jacobian, whose points parametrize quadratic polynomials with a “newly small” Galois group at the fifth stage of iteration.
Approximation Algorithms for Computing Maximin Share Allocations
Authors: Amanatidis Georgios , Markakis Evangelos , Nikzad Afshin , Saberi Amin
Published: December 2017

We study the problem of computing maximin share allocations, a recently introduced fairness notion. Given a set of
n
agents and a set of goods, the maximin share of an agent is the best she can guarantee to herself, if she is allowed to partition the goods in any way she prefers, into
n
bundles, and then receive her least desirable bundle. The objective then is to find a partition, where each agent is guaranteed her maximin share. Such allocations do not always exist, hence we resort to approximation algorithms. Our main result is a 2/3-approximation that runs in polynomial time for any number of agents and goods. This improves upon the algorithm of Procaccia and Wang (2014), which is also a 2/3-approximation but runs in polynomial time only for a constant number of agents. To achieve this, we redesign certain parts of the algorithm in Procaccia and Wang (2014), exploiting the construction of carefully selected matchings in a bipartite graph representation of the problem. Furthermore, motivated by the apparent difficulty in establishing lower bounds, we undertake a probabilistic analysis. We prove that in randomly generated instances, maximin share allocations exist with high probability. This can be seen as a justification of previously reported experimental evidence. Finally, we provide further positive results for two special cases arising from previous works. The first is the intriguing case of three agents, where we provide an improved 7/8-approximation. The second case is when all item values belong to {0, 1, 2}, where we obtain an exact algorithm.
Granulomatous Pancreas: A Case Report of Pancreatic Sarcoid
Authors: Bihun Tatiana , Diaz Yanet , Wenig Seth
Published: December 2017

Sarcoidosis is a chronic, systemic, noncaseating granulomatous disease process of unknown etiology. Sarcoidosis most commonly manifests in the lungs; however, gastrointestinal manifestations can occur. If in the GI tract, it is almost always found in the liver. Solitary pancreatic lesions are extremely rare, with less than 50 documented cases found in the literature. We present a case of a 61-year-old female, with a past medical history of sarcoidosis, who presented to the ER with unexpected weight loss, scleral icterus, right upper quadrant pain, and epigastric and back pain. US and MRI found a dilated common bile duct and mild dilation of the pancreatic duct, as well as a focal prominence in the head of the pancreas surrounded by areas of atrophy. A pancreaticoduodenectomy procedure was performed and fresh frozen sections were taken. The pathologist made a diagnosis of nonnecrotizing granulomatous pancreatitis. Pancreatic sarcoid is often asymptomatic and a benign finding on autopsy; however, clinicians should be mindful of pancreatic involvement when working up differential diagnosis for pancreatic masses.
Effect of Male Involvement on the Nutritional Status of Children Less Than 5 Years: A Cross Sectional Study in a Rural Southwestern District of Uganda
Authors: Kansiime Noel , Atwine Daniel , Nuwamanya Simpson , Bagenda Fred
Published: December 2017

Background. Undernutrition among children less than 5 years is still a public health concern in most developing countries. Fathers play a critical role in providing support in improving maternal and child health. There is little studied on male involvement and its measurement in child nutrition; therefore, this paper explores the level of male involvement in child feeding and its association with the nutritional status of the children less than 5 years of age.Methods. A cross sectional study among 346 households, 3 focus group discussions, and 4 key informant interviews were conducted in one rural district in Uganda. Adjusted odds ratios (aORs) and 95% confidence intervals (95% CI) of associated factors were estimated and focus group discussions and in-depth interviews were conducted and summarized into themes.Results. The study revealed the highest percentage of the males provided money to buy food for the children (93.6%), and only 9.8% have ever accompanied mothers to young child clinics.Conclusion. In this study, most males were involved in buying food for their children, and providing money for transport to young child clinics was associated with normal nutritional status of children less than 5 years in the study area.

Authors: Li Baolin , Li Nan , Wang Enyuan , Li Xuelong , Zhang Zhibo , Zhang Xin , Niu Yue
Published: December 2017

Generally, there are two important types of microseismic (MS) signals caused by mining and blasting activities at coal mines. The waveform characteristics of MS signals using FFT, STA/LTA method, and envelope analysis were studied to distinguish these two types of MS signals. The main results are as follows: the dominant frequency and duration of two types of signals are significantly different. The following peak envelope curves of two types of MS signals fit a power function. The power exponent was obtained to describe the attenuated speed of the MS signals. The attenuation of the coal mining MS signals is slower and more fluctuant than that of the blasting signal. Waveform characteristics consisting of the dominant frequency, duration, and attenuation coefficient were extracted as the discriminating parameters. The discriminating performance of these parameters was compared and discussed. Based on the waveform characteristics, a discriminant model for coal mining MS and blasting signals was established by using Fisher linear discriminant method and its performance was checked. The results show that the accuracy of the discriminant model is more than 85%, which can meet the requirements of MS monitoring at coal mines.

Published: December 2017

Purpose. To evaluate the clinical classification and characteristics of hereditary optic neuropathy patients in a single center in China. Method. Retrospective case study. Patients diagnosed with hereditary optic neuropathy between January 2014 and December 2015 in the neuro-ophthalmology division in Shanghai Eye and ENT Hospital of Fudan University were recruited. Clinical features as well as visual field, brain/orbital MRI, and spectrum domain optical coherence tomography (SD-OCT) were analyzed. Results. Eighty-two patients diagnosed by gene test were evaluated, including 66 males and 16 females. The mean age of the patients was 19.4 years (range, 5–46 years). A total of 158 eyes were analyzed, including 6 unilateral, 61 bilateral, and 15 sequential. The median duration of the disease was 0.5 year (range, 0.1–20 years). Genetic test identified 68 patients with Leber hereditary optic neuropathy, 9 with dominant optic neuropathy, and 2 with a Wolfram gene mutation. There was also one case of hereditary spastic paraplegia, spinocerebellar ataxia, and polymicrogyria with optic nerve atrophy, respectively. Conclusion. Leber hereditary optic neuropathy is the most common detected type of hereditary optic neuropathy in Shanghai, China. The detection of other autosomal mutations in hereditary optic neuropathy is limited by the currently available technique.
Circular RNAs: Biogenesis, Function, and a Role as Possible Cancer Biomarkers
Authors: Bolha Luka , Ravnik-Glavač Metka , Glavač Damjan
Published: December 2017

Circular RNAs (circRNAs) are a class of noncoding RNAs (ncRNAs) that form covalently closed continuous loop structures, lacking the terminal 5′ and 3′ ends. CircRNAs are generated in the process of back-splicing and can originate from different genomic regions. Their unique circular structure makes circRNAs more stable than linear RNAs. In addition, they also display insensitivity to ribonuclease activity. Generally, circRNAs function as microRNA (miRNA) sponges and have a regulatory role in transcription and translation. They may be also translated in a cap-independent manner in vivo, to generate specific proteins. In the last decade, next-generation sequencing techniques, especially RNA-seq, have revealed great abundance and also dysregulation of many circRNAs in various diseases, suggesting their involvement in disease development and progression. Regarding their high stability and relatively specific differential expression patterns in tissues and extracellular environment (e.g., body fluids), they are regarded as promising novel biomarkers in cancer. Therefore, we focus this review on describing circRNA biogenesis, function, and involvement in human cancer development and address the potential of circRNAs to be effectively used as novel cancer diagnostic and prognostic biomarkers.
A Review on the Medicinal Plant Dalbergia odorifera Species: Phytochemistry and Biological Activity
Authors: Ninh The Son
Published: December 2017

The crucial medicinal plant Dalbergia odorifera T. Chen species belongs to genus Dalbergia, with interesting secondary metabolites, consisting of main classes of flavonoid, phenol, and sesquiterpene derivatives, as well as several arylbenzofurans, quinones, and fatty acids. Biological studies were carried out on extracts, fractions, and compounds from this species involved in cytotoxic assays; antibacterial, antioxidative, anti‐inflammatory, antithrombotic, antiplatelet, antiosteosarcoma, antiosteoporosis, antiangiogenesis, and prostaglandin biosynthetic enzyme inhibition activities; vasorelaxant activities; alpha‐glucosidase inhibitory activities; and many other effects. In terms of the valuable resources for natural new drugs development, D. odorifera species are widely used as medicinal drugs in many countries for treatment of cardiovascular diseases, cancer, diabetes, blood disorders, ischemia, swelling, necrosis, or rheumatic pain. Although natural products from this plant have been increasingly playing an important role in drug discovery programs, there is no supportive evidence to provide a general insight into phytochemical studies on D. odorifera species and biological activities of extracts, fractions, and isolated compounds. To a certain extent, this review deals with an overview of almost naturally occurring compounds from this species, along with extensive coverage of their biological evaluations.

Published: December 2017

Occurrence of cerebral ischemia in the posterior circulation as a result of severe internal carotid artery disease and persistent trigeminal artery is rare. An 81-year-old man with medical history of hypertension and ischemic stroke presented with dizziness, nausea, and mild dysarthria. Magnetic resonance imaging of the brain revealed acute infarcts in the left internal carotid artery territory. CT angiogram revealed a persistent trigeminal artery (PTA) and severe atherosclerosis. The patient developed new neurological symptoms and repeat imaging revealed new acute infarcts in the PTA distribution. After undergoing a left carotid endarterectomy with no complications, the patient was discharged to a skilled nursing facility with no recurrence of ischemic stroke. This case adds a rare complication of an infrequent vascular anomaly to the limited body of the literature.
Performance Comparison of Reputation Assessment Techniques Based on Self-Organizing Maps in Wireless Sensor Networks
Authors: Sicari Sabrina , Rizzardi Alessandra , Grieco Luigi Alfredo , Coen-Porisini Alberto
Published: November 2017

Many solutions based on machine learning techniques have been proposed in literature aimed at detecting and promptly counteracting various kinds of malicious attack (data violation, clone, sybil, neglect, greed, and DoS attacks), which frequently affect Wireless Sensor Networks (WSNs). Besides recognizing the corrupted or violated information, also the attackers should be identified, in order to activate the proper countermeasures for preserving network’s resources and to mitigate their malicious effects. To this end, techniques adopting Self-Organizing Maps (SOM) for intrusion detection in WSN were revealed to represent a valuable and effective solution to the problem. In this paper, the mechanism, namely, Good Network (GoNe), which is based on SOM and is able to assess the reliability of the sensor nodes, is compared with another relevant and similar work existing in literature. Extensive performance simulations, in terms of nodes’ classification, attacks’ identification, data accuracy, energy consumption, and signalling overhead, have been carried out in order to demonstrate the better feasibility and efficiency of the proposed solution in WSN field.

Published: December 2017

An expeditious route to fused triazolo-pyrido benzoxazepines has been developed using flow and microwave-mediated cyclization chemistry. A range of substituted aryl hydrazides are coupled with a core chloroimine in good to excellent yield via a Pellizzari type process, producing 1,2,4-triazolo-pyrido [2,3-b] [1,5] benzoxazepines with structural similarity to known antipsychotic agents. Modifications allow for strategically functionalized derivatives, and installation of a fluoro group for use in PET imaging is also demonstrated. Given the affinity of the tricyclic core for 5-HT and dopamine receptors, the derivatives are expected to find utility in CNS research.

Published: December 2017

Purpose: Preclinical data established IL15 as a homeostatic factor and powerful stimulator of NK and CD8+ T-cell function, the basis for clinical testing.

Experimental Design: A first-in-human outpatient phase I dose escalation trial of subcutaneous (SC) rhIL15 was conducted in refractory solid tumor cancer patients. Therapy consisted of daily (Monday–Friday) subcutaneous injections of rhIL15 for two consecutive weeks (10 total doses/cycle). Clinical response was assessed by RECIST. Pharmacokinetics of rhIL15 and immune biomarkers were evaluated.

Results: Nineteen patients were treated with rhIL15 at dose levels of 0.25, 0.5, 1, 2, and 3 mcg/kg/day. Fourteen patients completed ≥ 2 cycles of therapy that was well tolerated. One serious adverse event (SAE), grade 2 pancreatitis, required overnight hospitalization. Enrollment was halted after a patient receiving 3 mcg/kg/day developed a dose-limiting SAE of grade 3 cardiac chest pain associated with hypotension and increased troponin. No objective responses were observed; however, several patients had disease stabilization including a renal cell carcinoma patient who continued protocol treatment for 2 years. The treatment induced profound expansion of circulating NK cells, especially among the CD56bright subset. A proportional but less dramatic increase was found among circulating CD8+ T cells with maximal 3-fold expansion for the 2 and 3 mcg/kg patients.

Conclusions: SC rhIL15 treatment was well tolerated, producing substantial increases in circulating NK and CD8+ T cells. This protocol establishes a safe outpatient SC rhIL15 regimen of 2 mcg/kg/day dosing amenable to self-injection and with potential as a combination immunotherapeutic agent.

Digital Applications in Cytopathology: Problems, Rationalizations, and Alternative Approaches
Authors: Chantziantoniou Nikolaos , Mukherjee Maheswari , Donnelly Amber D. , Pantanowitz Liron , Austin R. Marshall
Published: November 2017

Objective: The aim of this work was to raise awareness of problems using digital applications for examining, teaching, and applying telecytology at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia; University of Nebraska Medical Center (UNMC), Omaha, NE, USA; and University of Pittsburgh Medical Center (UPMC), Pittsburgh, PA, USA. The objective was to rationalize problems and propose alternative digital approaches. Study Design: We sought to identify solutions to improve the following: (a) interpretive examination scores at KAMC for complex cytological templates (i.e., high-grade squamous intraepithelial lesions [HSIL]) when using static digital images (SDI) of cells in regions of interest (ROI); (b) visualization of cells in 3D clusters when teaching at UNMC using 2D and 3D whole-slide imaging (WSI); and (c) visualization of cells through streaming telecytology at UPMC. Results: Composite SDI (CSDI) improved test scores for complex interpretations (i.e., HSIL) by converging diagnostic criteria from multiple ROI. Multiplane focusing through z-stacked WSI facilitated the teaching of cytological entities characterized by 3D cell clusters and consultative telecytology through robotic cell analysis. Conclusions: Adequately visualized cytomorphology and multiplane focusing are essential for virtual cytopathology examinations, teaching, or consultative telecytology. Visualization of diagnostic criteria through 2D or 3D imaging is critical. Panoptiq panoramic WSI with integrated z-stacked video clips enables optimal applied telecytology.
Late Effects and Long-Term Follow-Up after Cancer in Childhood
Authors: Langer Thorsten , Grabow Desiree , Steinmann Diana , Wörmann Bernhard , Calaminus Gabriele
Published: November 2017

Today, 80% of children and adolescents with cancer survive their disease. From the results of aftercare research arises the question: Are the survivors also healthy? Many late effects depend on the type of cancer and its treatment. Patients with brain tumors and with malignant sarcomas are very often affected by secondary diseases. Data from the USA report that around 2/3 of all patients still living 30 years after their cancer treatment in childhood suffer from late complications. Equivalent figures for Germany were previously unavailable. In accordance with the guidelines, regular follow-ups to diagnose a relapse or possible late effects have mostly been carried out in the primary children's hospitals. In adolescence and in young adulthood, this regimen does no longer serve the patientsʼ mental and physical needs. To ensure appropriate care for this maturing patient group, interdisciplinary approaches (e.g., aftercare consultations) are required in which pediatric oncologists collaborate with colleagues from the field of internal medicine and other disciplines. Individual, risk-adapted (depending on the cancer treatment) aftercare plans based on pre-existing aftercare recommendations must be drawn up for every patient and to secure the early diagnosis of possible late effects. The conservation of health and quality of life after cancer treatment (in all age groups) will in the future not only represent a social but also an economic consideration.
A afirmação do português como língua de ciência: o caso da Botânica
Authors: Pereira Rui Abel
Published: December 2017

Em uma época em que o latim imperava como língua da ciência, surge em Coimbra, publicada pela Real Officina da Universidade, uma obra determinante para o estudo e o ensino da Botânica em Portugal. Trata-se do Diccionario dos termos technicos de historia natural, de Domingos Vandelli. Nesta obra, Vandelli transpõe para o português a terminologia latina usada por Lineu e outros naturalistas europeus, o que, para além de ser uma marca de modernidade, torna acessível a um maior número de falantes do português o estudo das ciências naturais. Neste artigo, além da análise da importância e das particularidades linguísticas da obra – algumas das quais decorrentes da origem do autor, pela sua condição de falante não nativo do português –, prestar-se-á atenção aos aspetos formais da elaboração do texto e às soluções encontradas pelo autor na tradução dos termos latinos.
Os processos de elisão e degeminação no português de São Tomé e Príncipe
Authors: Balduino Amanda Macedo , Bandeira Manuele , Freitas Shirley
Published: December 2017

A República de São Tomé e Príncipe é um país multilíngue, onde são faladas línguas crioulas, como o lung’ie, o santome e o angolar, além do português, língua oficial desde 1975. Assume-se que o português santomense (PS) é caracterizado pela nativização de uma L2 (segunda língua) em uma L1 (primeira língua ou língua nativa). Dessa forma, adquirido em um primeiro momento como L2, o português é transmitido como input para as gerações mais novas, consolidando-se posteriormente como L1 (Gonçalves, 2010). Essa transição pode suscitar mudanças e adaptações estruturais que, em conjunto com o contexto de contínuo contato interlinguístico, despertam a possibilidade de afastamento do PS das demais variedades do idioma, nomeadamente o português europeu (PE) e o português brasileiro (PB). Baseado na análise de um corpus naturalístico, o objetivo deste estudo é verificar a existência dos processos de elisão e degeminação no PS e descrevê-los analiticamente. Em decorrência de uma limitação de dados, bem como por uma questão de recorte metodológico, não abarcaremos a ditongação, preferindo focar nos processos mencionados. O estudo dos dados demonstrou que ambos processos de fato ocorrem em PS. Em geral, a contraposição da análise dedicada ao PS com os resultados já obtidos para o PB indica que, ao mesmo tempo que tais variedades se aproximam, ao apresentarem contextos segmentais e suprassegmentais de aplicação semelhantes, o PS demonstra, também, características singulares.

Published: December 2017

Background and Purpose—

This study aimed to investigate whether pulse pressure (PP) obtained during the acute stage of ischemic stroke can be used as a predictor for future major vascular events.

Methods—

Using a multicenter prospective stroke registry database, patients who were hospitalized for ischemic stroke within 48 hours of onset were enrolled in this study. We analyzed blood pressure (BP) data measured during the first 3 days from onset. Primary and secondary outcomes were time to a composite of stroke recurrence, myocardial infarction, all-cause death, and time to stroke recurrence, respectively.

Results—

Of 9840 patients, 4.3% experienced stroke recurrence, 0.2% myocardial infarction, and 7.3% death during a 1-year follow-up period. In Cox proportional hazards models including both linear and quadratic terms of PP, PP had a nonlinear J-shaped relationship with primary (for a quadratic term of PP,
P
=0.004) and secondary (
P
<0.001) outcomes. The overall effects of PP and other BP parameters on primary and secondary outcomes were also significant (
P
<0.05). When predictive power of BP parameters was compared using a statistic of −2 log-likelihood differences, PP was a stronger predictor than systolic BP (8.49 versus 5.91; 6.32 versus 4.56), diastolic BP (11.42 versus 11.05; 10.07 versus 4.56), and mean atrial pressure (8.75 versus 5.91; 7.03 versus 4.56) for the primary and secondary outcomes, respectively.

Conclusions—

Our study shows that PP when measured in the acute period of ischemic stroke has nonlinear J-shaped relationships with major vascular events and stroke recurrence, and may have a stronger predictive power than other commonly used BP parameters.

Published: December 2017

The confused taxonomy of the east Palaearctic pear psyllids, serious pests on cultivated pear, is reviewed. Fifty-six nominal species have been reported from Pyrus, 25 of which we consider valid and ten as not being associated with Pyrus. Our taxonomic revision suggests that, in Korea, four Cacopsylla species develop on pear: the univoltine C. burckhardti Luo et al. previously misidentified as C. pyrisuga (Foerster), the polyvoltine, seasonally dimorphic C. jukyungi (Kwon) (winter form ‘cinereosignata’ Luo et al., summer form ‘jukyungi’), commonly found in Korean pear orchards, and C. maculatili Li (winter form ‘maculatili’, summer form ‘qiuzili’ Li) previously misidentified as C. pyricola (Foerster) by some authors, as well as the probably polyvoltine but not dimorphic C. sandolbaea (Park & Lee). The former three species (C. burckhardti, C. jukyungi, misidentified as C. chinensis (Yang & Li), and C. maculatili) occur also in Japan. Keys to the adult and fifth instar immatures as well as short biological notes are provided, and C. jukyungi and C. sandolbaea are redescribed. Following nomenclatorial changes are proposed: Cacopsylla betulaefoliae (Yang & Li, 1981) = Psylla heterobetulaefoliae Yang & Li, 1981, syn. nov.; Cacopsylla bidens (Šulc, 1907) = Psylla jiangli Yang & Li, 1981, syn. nov.; Cacopsylla jukyungi (Kwon) = C. cinereosignata Luo et al., syn. nov.; Cacopsylla maculatili Li = C. qiuzili Li, syn. nov.; Cacopsylla nigella (Konovalova), comb. nov. from Psylla. The synonymy of P. obongsana Kwon with C. sandolbaea is confirmed.
Increasing diversity of land planarians (Platyhelminthes: Geoplanidae) in the Interior Atlantic Forest with the description of two new species and new records from Argentina
Authors: NEGRETE LISANDRO , BRUSA FRANCISCO
Published: December 2017

Here, we describe two new species of land planarians of the genera Pasipha and Imbira from the Atlantic Forest of Argentina: Pasipha quirogai sp. nov. and Imbira negrita sp. nov. Their external features and internal anatomy distinguish them from their congeners. Pasipha quirogai sp. nov. is about 40mm long, characterized by brown beige dorsal pigmentation with a golden yellow median band and thin graphite black para-median stripes, cylindrical pharynx, extrabulbar prostatic vesicle with paired proximal portion, male atrium with small folds in its proximal part, and female canal opening into the dorso-caudal wall of the female atrium. Imbira negrita sp. nov. is about 110mm long, with jet black dorsal pigmentation, pharynx collar-type, short female canal opening in the postero-dorsal portion of the female atrium, and epithelial lining of female atrium with stratified appearance. We also provide exhaustive descriptions of Geoplana quagga, Obama ladislavii, and Paraba multicolor, all recorded for the first time in Argentina, by analysing anatomical features of taxonomic relevance. In addition, we improve the description of G. quagga, mainly regarding the musculature, secretory cells, and the copulatory apparatus.

An aggregation of two males of Timulla bitaeniata (Spinola, 1841), three single males T. rufogastra (Lepeletier, 1845) and another two males T. rufogastra (Lepeletier, 1845) in copula with two females of T. eriphyla Mickel, 1938 is documented, described and discussed. A new synonymy is proposed for Mutilla rufogastra Lepeletier de Saint-Fargeau, 1845 [=Timulla (Timulla) eriphyla Mickel, 1938, syn. nov.] based on the mating pairs.
A potential theory approach to an algorithm of conceptual space partitioning
Authors: Urban Roman , Grzelińska Magdalena
Published: December 2017

A potential theory approach to an algorithm of conceptual space partitioningThis paper proposes a new classification algorithm for the partitioning of a conceptual space. All the algorithms which have been used until now have mostly been based on the theory of Voronoi diagrams. This paper proposes an approach based on potential theory, with the criteria for measuring similarities between objects in the conceptual space being based on the Newtonian potential function. The notion of a fuzzy prototype, which generalizes the previous definition of a prototype, is introduced. Furthermore, the necessary conditions that a natural concept must meet are discussed. Instead of convexity, as proposed by Gärdenfors, the notion of geodesically convex sets is used. Thus, if a concept corresponds to a set which is geodesically convex, it is a natural concept. This definition applies, for example, if the conceptual space is an Euclidean space. As a by-product of the construction of the algorithm, an extension of the conceptual space to d-dimensional Riemannian manifolds is obtained. Algorytm podziału przestrzeni konceptualnych przy użyciu teorii potencjałuW niniejszej pracy zaproponowany został nowy algorytm podziału przestrzeni konceptualnej. Dotąd podział taki zazwyczaj wykorzystywał teorię diagramów Voronoi. Nasze podejście do problemu oparte jest na teorii potencjału Miara podobieństwa pomiędzy elementami przestrzeni konceptualnej bazuje na Newtonowskiej funkcji potencjału. Definiujemy pojęcie rozmytego prototypu, który uogólnia dotychczas stosowane definicje prototypu. Ponadto zajmujemy się warunkiem koniecznym, który musi spełniać naturalny koncept. Zamiast wypukłości zaproponowanej przez Gärdenforsa, rozważamy linie geodezyjne w obszarze odpowiadającym danemu konceptowi naturalnemu, otrzymując warunek mówiący, że koncept jest konceptem naturalnym, jeżeli zbiór odpowiadający temu konceptowi jest geodezyjnie wypukły. Ta definicja pokrywa się w przypadku, gdy przestrzenią konceptualną jest przestrzeń euklidesowa. Jako produkt uboczny konstrukcji naszego algorytmu rozważamy dość ogólne przestrzenie konceptualne będące d-wymiarowymi rozmaitościami Reimanna.

On The dictionary of active Polish and Ukrainian phraseology [Leksykon aktywnej frazeologii polskiej i ukraińskiej]. Contrastive linguistics and cultureThe Dictionary of Active Polish and Ukrainian Phraseology [Leksykon aktywnej frazeologii polskiej i ukraińskiej] is the first publication of its kind in the history of Polish and Ukrainian lexicography. It consists of equivalent phrasal units in Polish and Ukrainian. The innovative aspect of the lexicon is that it uses a semantic metalanguage to establish equivalent units. The authors developed a new method of searching for equivalent units which uses the meaning — not the form — as the starting point. This method enables the identification of equivalent units in both languages. Moreover, it enables the identification of units that do not have equivalents. The units which lack equivalents are usually deeply rooted in Poland’s or Ukraine’s historical and cultural context, and are thus defined as culturemes. Even though they lack equivalents, it was decided not to exclude them from the Leksykon’s structure, as they are actively used by the speakers of Polish and Ukrainian. This paper provides an overview of the Leksykon’s methodology and presents the authors’ definition of phraseologism. The most important points in the paper are illustrated with a number of example entries from the dictionary. The primary focus of the paper rests on phrasal units which lack equivalents. O Leksykonie aktywnej frazeologii polskiej i ukraińskiej. Konfrontacja językowa a kulturaOpracowywany przez nas Leksykon aktywnej frazeologii polskiej i ukraińskiej jest pierwszym dziełem tego typu w historii leksykografii polskiej i ukraińskiej. W leksykonie prezentujemy odpowiedniości jednostek frazeologicznych w języku polskim i ukraińskim za pomocą semantycznego języka pośrednika. Wyznaczenie kierunku od znaczenia ku formie pozwoliło dobrać ekwiwalenty jednostek frazeologicznych w obu językach. Zestawienie polskiego i ukraińskiego materiału pozwoliło również wyodrębnić poszczególne jednostki nieposiadające odpowiedników. Jednostki te są ściśle związane z kulturą i historią narodu polskiego i ukraińskiego. W związku z tym zaliczamy je do kulturemów, ale nie pomijamy w strukturze leksykonu ze względu na ich aktywność w mówionym języku współczesnym. W niniejszym artykule prezentujemy metodologię zastosowaną w leksykonie, definicję roboczą frazeologizmu w leksykonie, przykładowe hasła oraz skupiamy się na pokazaniu jednostek frazeologicznych nieposiadających pełnej odpowiedniości.
Kin term patterns and language familie

Kin term patterns and language familieThe anthropologist G. P. Murdock has found a strong correlation between the kin term patterns (or feature-values) for the relative (feature) “sibling” and language families. This important finding for language classification, however, has not been pursued further. In particular, it has not yet been tested whether the kin term patterns domain as a whole, including the patterns for other features (“grandparents”, “uncles”, “aunts”, “nephews and nieces”, etc.), is sufficient to demarcate all language families from one another. This paper presents a large-scale computational profiling of all language families in terms of their kin term patterns. The most significant findings are: (i) that language families can be quite neatly differentiated on the basis of their kin term patterns, and therefore these patterns may be considered as strong indicators of genetic affiliation, and (ii) that the kin term patterns for the features “nephews and nieces (= siblings' children)”, “siblings”, and “siblings-in-law” — i.e. all features including the idea of siblings — are the best predictors of genetic affiliation, as they are significantly more frequently used in the profiles than any other feature.  Modele terminologii powinowactwa i pokrewieństwa a rodzina językowaAntropolog G. P. Murdock odkrył silny związek między modelami powinowactwa i pokrewieństwa dla krewnych (rodzeństwa) a rodzinami językowymi. To ważne odkrycie w klasyfikacji języków nie było odpowiednio dalej wykorzystywane. W szczególności nie sprawdzono jeszcze, czy domena modeli powinowactwa i pokrewieństwa jako całości, w tym modele dla innych cech („dziadkowie”, „wujkowie”, „ciotki”, „siostrzeńcy i siostrzenice” itp.) są wystarczająco ukształtowane we wszystkich rodzinach językowych. W niniejszym artykule przedstawiono profilowanie komputerowe na dużą skalę wszystkich rodzin językowych pod kątem ich modeli powinowactwa i pokrewieństwa. Najważniejsze wnioski są następujące: (i) rodziny językowe mogą być zróżnicowane na podstawie modeli powinowactwa i pokrewieństwa, dlatego też te modele mogą być uważane za silne wskaźniki genetycznej przynależności, oraz (ii) modele dla cechy „siostrzeńcy i siostrzenice (= dzieci rodzeństwa)”, „rodzeństwo” i „rodzeństwo przyrodnie” - czyli wszystkie cechy, w tym rodzeństwa - są najlepszymi przesłankami genetycznej przynależności, ponieważ są znacznie częściej używane w profilach niż jakakolwiek inna funkcja.
La critique de cinéma comme activité rhétorique

Film review as a rhetorical activityThe paper discusses the discursive construction of persuasiveness in media language. Analysing the corpus consisting of eighty reviews of two French comedies “Intouchables” (2011) and “Qu'est-ce qu'on a fait au Bon Dieu?” (2014), several invariant characteristics of the genre `film review' are established in the light of its deliberative dimension which consists in using various discursive strategies of persuasion submitted to the phatic function based on the principle of movere and delectare. Since the mentioned strategies assume that the discourse aims at influencing the addressees' will and decisions, they reflect some of the persuasive techniques used in advertising discourse, especially with regard to rhetorical means of interpretation, suggestion and evaluation such as colloquial expressions, questions, directive speech acts, collocative pronouns and generic quantifiers. Thus, the issues addressed in the study concern a set of parameters governing the attractiveness of the message in order to reinforce or weaken the recipient's attitude towards the presented object. These parameters stem from shared values and convictions exploring automatic mental triggers connected with the peripheral route of persuasive influence. Recenzja filmowa jako działanie retoryczneCelem analizy jest przedstawienie dyskursywnego konstruowania perswazyjności w języku mediów. Na bazie korpusu składającego się z osiemdziesięciu recenzji dwóch francuskich komedii „Nietykalnych” (2011) i „Za jakie grzechy, dobry Boże?” (2014) omówiono kilka inwariantnych cech gatunku „recenzji filmowej”, przedstawionych w świetle jej deliberatywności, polegającej na użyciu różnorakich dyskursywnych strategii perswazyjnych, zależnych od fatycznej funkcji języka, działającej w oparciu o reguły movere i delectare. Ponieważ we wspomnianych strategiach zakłada się, że celem dyskursu jest wpływanie na wolę i decyzje odbiorcy, odzwierciedlają one niektóre z perswazyjnych technik dyskursu reklamowego, w szczególności te, które związane są z retorycznymi środkami interpretacji, sugestii i wartościowania jak wyrażenia potoczne, pytania, akty dyrektywne, zaimki kolektywne oraz kwantyfikatory ogólne. Z tego powodu, kwestie omawiane w niniejszej pracy dotyczą środków zawiadujących atrakcyjnością komunikatu, służącej wzmocnieniu lub osłabieniu opinii odbiorcy względem prezentowanego obiektu. Środki te wywodzą się z wartości i przekonań uznanych za wspólne, wykorzystując przy tym automatyczne psychologiczne mechanizmy, związane z argumentacją peryferyjnego toru perswazji.

This service will make it much easier for anybody using reanalysis to access multiple datasets using an approach similar to that of phase 5 of the Coupled Model Intercomparison Project (CMIP5). Experienced users as well as students will find the standardized formatted data convenient to use.
A Spatial and Temporal Analysis of 30-Day Heavy Snowfall Amounts in the Eastern United States, 1900–2016
Authors: Changnon David
Published: December 2017

Heavy 30-day snowfall amounts were evaluated to identify spatial and temporal characteristics east of the Rocky Mountains in the United States during the period 1900–2016. An extensive data assessment identified 507 stations for use in this long-term climate study. The top 30-day heavy snowfall amount and the average of the top five 30-day heavy snowfall amounts were examined. Both amounts generally increased with latitude; however, much higher amounts were found downwind of the Great Lakes, at higher elevations, or in locations impacted by topographic features (e.g., Rockies, Black Hills, and Appalachians). When compared with the 1981–2010 average winter snowfall, the top 30-day amount was found to be greater than the winter average in most areas of the eastern United States. The number of stations experiencing a top-five 30-day heavy snowfall period in a winter ranged from 1 to 128 (1959/60), with a greater overall occurrence in the second half of the 117-yr period. Six episodes had 10% or more stations experiencing one of the top five 30-day snowfall amounts, with the February–March 1960 episode impacting 124 stations, and these episodes were associated with large negative 500-hPa height anomalies. The northern Great Plains, Great Lakes, Midwest, and Northeast experienced more top-five periods in the second half of the 117-yr period, whereas most of the southern states experienced top-five periods throughout the study’s time frame. Examining extremes at periods beyond the daily event and less than the season contributes to our knowledge of climate and provides useful information to snow-sensitive sectors.
Hydroclimatology of the Missouri River Basin

Despite the importance of the Missouri River for navigation, recreation, habitat, hydroelectric power, and agriculture, relatively little is known about the basic hydroclimatology of the Missouri River basin (MRB). This is of particular concern given the droughts and floods that have occurred over the past several decades and the potential future exacerbation of these extremes by climate change. Here, observed and modeled hydroclimatic data and estimated natural flow records in the MRB are used to 1) assess the major source regions of MRB flow, 2) describe the climatic controls on streamflow in the upper and lower basins , and 3) investigate trends over the instrumental period. Analyses indicate that 72% of MRB runoff is generated by the headwaters in the upper basin and by the lowest portion of the basin near the mouth. Spring precipitation and temperature and winter precipitation impacted by changes in zonal versus meridional flow from the Pacific Ocean play key roles in surface water supply variability in the upper basin. Lower basin flow is significantly correlated with precipitation in late spring and early summer, indicative of Atlantic-influenced circulation variability affecting the flow of moisture from the Gulf of Mexico. Although increases in precipitation in the lower basin are currently overriding the effects of warming temperatures on total MRB flow, the upper basin’s long-term trend toward decreasing flows, reduction in snow versus rain fraction, and warming spring temperatures suggest that the upper basin may less often provide important flow supplements to the lower basin in the future.
Successful Prediction of a Left Nonrecurrent Laryngeal Nerve in a Patient With Right-Sided Aorta and Aberrant Left Subclavian Artery

Published: December 2017

Background:

Left nonrecurrent laryngeal nerve (LNRLN) is an extremely rare anatomic variant. The development of such anatomic variation requires the regression of both the fourth (aortic arch) and sixth (ductus arteriosus, DA) arches on the left side. Preoperative prediction of this variant is difficult but might reduce risk of nerve injury.

Methods:

A 34-year-old female was indicated for thyroidectomy for a 2.4 cm follicular neoplasm and Graves’ disease. Due to a positive medical history of 22q11.2 microdeletion and unexplained left vocal cord paralysis, a preoperative chest computed tomography (CT) scan was obtained and revealed a right-sided aorta (RSA) and aberrant left subclavian artery (ALSA) without Kommerell’s diverticulum. A left-sided NRLN was then highly suspected.

Results:

Thyroidectomy was performed under general anesthesia with the utilization of intraoperative laryngeal nerve monitoring. A LNRLN was confirmed intraoperatively.

Conclusions:

Right-sided aorta and ALSA indicate embryologic regression of the left fourth primitive aortic arch. The absence of Kommerell’s diverticulum at the origin of the ALSA indicates the lack of high-pressure blood flow from the pulmonary artery to the ALSA through the ductus arteriosus during embryogenesis, suggesting the embryologic regression of the left sixth primitive aortic arch. The presence of all 3 radiologic features thus highly suggests the possibility of a LNRLN.
