Published: January 2017

Solanesol is an important pharmaceutical intermediate that also affects the quality of tobacco (Nicotiana tabacum L.) leaves. To explore novel applications of tobacco leaves and to broaden the genetic basis of flue‐cured tobacco breeding varieties, the solanesol content of 168 Chinese flue‐cured tobacco germplasm resources, planted at four geographical regions of China in 2014 and 2015, was determined using ultra‐performance liquid chromatography. Solanesol content and genetic diversity were analyzed using additive main effects and multiplicative interaction model (AMMI) and simple sequence repeat (SSR) markers. The results indicated that solanesol content of flue‐cured tobacco ranged from 0.70 to 4.13% and the mean content of samples from the northern regions (2.60%) were higher than that from the southern regions (1.67%) of China. Genotypes, environments, and their interactions all had significant impacts on the solanesol content of tobacco leaves. Additionally, high‐solanesol varieties Dashuba2106, Changboyan, and Heiyeyan and low‐solanesol cultivars Zhongyan90, CF90NF, Zhongyan102 had the highest hereditary stability. These 168 accessions were divided into introduced (Y), breeding (X), and local (D) groups according to origins. Using 69 SSR primer pairs selected from 1196 primer combinations, we scored 271 alleles, of which 229 (84.50%) were polymorphic. Shannon's index, Nei's index, and polymorphism information content value were 0.8006, 0.4613, and 0.4014, respectively, suggesting a wide genetic basis of these 168 germplasm resources. Among the three groups, the D group showed the richest genetic diversity, while the Y group exhibited the lowest genetic diversity. The Y and X groups had the highest genetic similarity (0.9657), followed by X group versus D group (0.9462) and Y group versus D group (0.9019). Findings in this study should have great importance for future exploitation and utilization of solanesol from tobacco leaves.
Disjointed Confessions: Adikia and Radical Deradicalization in Schlingensief’s Hamlet
Authors: Currie Janus C.
Published: January 2017

In 2001, in Zürich Switzerland, German director Christoph Schlingensief staged a version of Shakespeare’s Hamlet. In this version’s famous mousetrap scene, in which Hamlet wants to force his uncle to confess to fratricide, all the players of the mise en abyme are portrayed by a group of neo-Nazis endeavouring to separate themselves from the right–wing scene. In a dramatic break from Shakespeare’s text the group go on to share their own personal experiences with the audience. The production attempted to comment on and create debate about the ‘rottenness’ of the State, not just Switzerland, amid the rise in approval ratings and growing influence of far-right parties in the surrounding countries. I posit that Schlingensief’s project is a form of radical deradicalization (i.e., a radical method of deradicalizing neo-Nazis). This paper analyses Schlingensief’s Hamlet by utilizing the concepts of adikia (disjointure, dislocation, injustice) and dike (jointure, ordering, justice), which go back to the oldest extant Greek text: the Anaximander fragment. Drawing on Martin Heidegger and Jacques Derrida’s reinterpretations of adikia and dike I endeavour to illustrate how Schlingensief’s work attempts to intervene in the disjointure caused by the contemporary politics of fear by bringing adikia to the production of Hamlet itself.

Published: January 2017

The current investigation was conducted to evaluate the potency of salinity to enhance the nutraceutical properties of fenugreek (Trigonella foenum-graecum L.) seedlings. Gradual doses of NaCl solution (0, 50, 100, 150 and 200 mM) were applied and the nutritional value of seedlings was determined 2 and 5 days post- germination. Moreover, the antioxidant and antimicrobial activity along with the phenolic content of the considered seedlings were assessed. The obtained results manifested that salt application to different levels could increase the amount of protein, N, Zn and Cu in the 2- and 5- day old seedlings. Salinity could also raise the amount of vitamin C, B1, B2 and B9 but only in one stage. Conversely, the amount of reducing, non-reducing and total sugars as well as that of Fe declined under stress. Compared with their unsalted synonyms, water and methanolic extracts of salt- treated fenugreek seedlings had higher H2O2- scavenging activity in the two stages, while their reducing power and free radicles- scavenging activities were promoted in the second stage only. Regarding the antimicrobial activity, water and methanolic extracts of the stressed seedlings generally exhibited better antimicrobial activity against some pathogenic microbes especially Erwinia carotovora, Bacillus subtilis and Candida albicans. Only in the second stage, most of the employed salt concentrations increased the titer of tannins, saponins, alkaloids, flavonoids and total phenols in the aqueous and alcoholic extracts. Therefore, it is recommended to salinize young fenugreek seedlings to improve its health benefits in a simple, low- cost and low- risk approach.

Published: January 2017

OBJECTIVE To examine bile acid composition of gallbladder contents in dogs with gallbladder mucocele and biliary sludge.

ANIMALS 18 dogs with gallbladder mucocele (GBM group), 8 dogs with immobile biliary sludge (i-BS group), 17 dogs with mobile biliary sludge (m-BS group), and 14 healthy dogs (control group).

PROCEDURES Samples of gallbladder contents were obtained by use of percutaneous ultrasound-guided cholecystocentesis or during cholecystectomy or necropsy. Concentrations of 15 bile acids were determined by use of highperformance liquid chromatography, and a bile acid compositional ratio was calculated for each group.

RESULTS Concentrations of most bile acids in the GBM group were significantly lower than those in the control and m-BS groups. Compositional ratio of taurodeoxycholic acid, which is 1 of 3 major bile acids in dogs, was significantly lower in the GBM and i-BS groups, compared with ratios for the control and m-BS groups. The compositional ratio of taurocholic acid was significantly higher and that of taurochenodeoxycholic acid significantly lower in the i-BS group than in the control group.

CONCLUSIONS AND CLINICAL RELEVANCE In this study, concentrations and fractions of bile acids in gallbladder contents were significantly different in dogs with gallbladder mucocele or immobile biliary sludge, compared with results for healthy control dogs. Studies are needed to determine whether changes in bile acid composition are primary or secondary events of gallbladder abnormalities.
Scott Moir’s “Funny Face”: Make Belief, Camp, and Masculine Performance
Authors: Green Reina
Published: January 2017

Despite the high number of homosexual male athletes involved in figure skating, heteronormative performance is integral to the sport, particularly in ice dance which requires teams or “couples” to portray a close relationship on the ice. In their 2012 free dance programme, Canadian ice dance champions and Olympic gold medalists Tessa Virtue and Scott Moir facilitated their portrayal of a romantic relationship by skating to music from Funny Face, a 1957 Hollywood musical starring Fred Astaire and Audrey Hepburn. Using Richard Schechner’s distinction between “make believe” and “make belief” performances and Susan Sontag’s definition of camp, I argue that Moir not only wants to “make believe” that he is performing the role of Fred Astaire, but also wishes to “make belief” that he is as skilled as the American dancer in presenting his partner. Moir, though, introduces a camp aesthetic into the performance through his exaggerated facial expressions and gestures which causes him rather than Virtue to be the feminized object of the gaze. This element of camp thereby introduces a queer resistance to the heteronormative gender roles demanded in ice dance and highlights how male figure skaters have to make belief in their masculinity.

Published: January 2017

Phase 2 final results are described for the FHWA Exploratory Advanced Research project titled Heavy Truck Cooperative Adaptive Cruise Control: Evaluation, Testing, and Stakeholder Engagement for Near Term Deployment, which evaluates the commercial feasibility of driver-assistive truck platooning (DATP). The project was led by Auburn University, in partnership with Peloton Technology, Peterbilt Trucks, Meritor WABCO, and the American Transportation Research Institute. DATP is a form of cooperative adaptive cruise control for heavy trucks (two-truck platoons). It takes advantage of the increasing maturity of vehicle-to-vehicle (V2V) communications (and the expected widespread deployment of V2V connectivity based on dedicated short-range communications over the next decade) to improve freight efficiency, fleet efficiency, safety, and highway mobility as well as reduce emissions. Notably, truck fleets can implement DATP regardless of the regulatory timeline for dedicated short-range communications. The Phase 2 analysis built on Phase 1 and included a testing program of a DATP prototype (with detailed SAE Type 2 fuel economy testing), wireless communications optimization, traffic modeling to understand the impact on roadways at various levels of market penetration, and additional analysis of methods to find DATP partners as well as aerodynamic simulations to understand drag on the vehicles. Detailed analysis of the fuel economy testing data is provided.

Published: January 2017

Tumour microsatellite instability (MSI) is useful in identifying patients with hereditary non-polyposis colorectal cancer (HNPCC) with defective DNA mismatch repair (MMR} genes. A reference Bethesda panel has limitations resulting from the inclusion of dinucleotide markers, which are less sensitive and specific for detection of tumours with MMR deficiencies. We developed a multiplex PCR assay with additional four mononucleotide markers and one dinucleotide marker (NR-21, NR-24, BAT-40, TGF-BetaR and D18S58) for a rapid and proper classification of MSI-H, MSI-L and MSS colorectal cancers. Two tetranucleotide markers were added to identify sample mix-ups and/or contamination. Results: all the 44 cases test cases were in agreement with previous classification except for three cases: one case MSI-H-Bethesda unstable only for dinucleotides markers shifted to MSI-L category and two cases MSI-L-Bethesda unstable for mononucleotide markers shifted to MSI-H category. Immunohistochemistry analysis revealed that these two MSI-H cases did not expressed hMLH1 and they were found to be methylated at the MLH1 promoter, while the first one that shifted to MSI-L showed MMR protein expression. Conclusion: a complete panel of ten markers including four dinucleotide and six mononucleotide microsatellites allows accurate evaluation of tumor MSI status.

In the present study, the use of a robust and sensitive mass spectrometry based protein profiling analysis was tested as diagnostic tools for women with an ovarian tumor. The potential additional diagnostic value of serum protein profiles independent of the information provided by CA125 were also investigated.

Protein profiles of 113 serum samples from women with an ovarian tumor (54 malign and 59 benign) were generated using MALDI-TOF MS. A total of 98 peaks with a significant difference (p< 0.01) in intensity between women with benign tumors/cysts and malignant ovarian tumors were identified. After average linkage clustering, a profile of 46 statistical significant mass peaks was identified to distinguish malignant tumors and benign tumors/cysts.

In the subgroup of women with normal CA125 values (⩽ 35 U/mL) (62 patients) 36 of the 504 mass peaks showed significant (p< 0.05) differences in intensity between benign and malignant disease. After average linkage clustering, 25 statistical significant mass values were identified in this clinical difficult and important subgroup presenting with normal CA125 values.

The current study demonstrates the potential of mass spectrometry based serum protein profiling as a diagnostic tool in discrimination between benign ovarian tumors/cysts and malignant ovarian tumors. Additionally, the method provided diagnostic information independent of CA125.

Published: January 2017

Objectives:

Oxidative stress and pro-inflammatory mediators have been implicated in breast carcinogenesis. We attempted to evaluate the markers of oxidative stress, antioxidant mechanism and the inflammatory pathway in patients with breast cancer.

Methods:

This study was carried out in departments of Biochemistry and Surgery, Maulana Azad Medical College and associated Hospitals, New Delhi, India. A total of 60 cases of carcinoma of the breast and 60 healthy controls were included in the study. The parameters that were assayed include markers of oxidative stress-conjugated dienes, thiobarbitone reactive substances (TBARS), antioxidants-superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) and markers of inflammation-interleukin-6(IL-6) and ferritin.

Results:

There was a significant decline in the antioxidant levels and a significant rise in oxidant levels in patients with carcinoma of the breast, compared to controls. The inflammatory markers-IL-6 and ferritin-were also significantly higher in patients with breast cancer. A significantly positive correlation was observed between the IL-6 levels and conjugated dienes with the stage of breast carcinoma; whilst a significantly negative correlation was observed between the levels of conjugated dienes and superoxide dismutase and superoxide dismutase levels with the disease staging.

Conclusions:

This study underlines the interplay between inflammatory pathways and oxidative stress in the pathogenesis of breast cancer.

Mini Abstract:

An intense research is underway to identify the possible risk factors and the molecular mechanisms involved in pathogenesis of breast cancer. Inflammation and oxidative stress are two such etiologies investigated in our study.
Ranking regular seasons in the NBA’s Modern Era using grey relational analysis
Authors: Pradhan Sean
Published: January 2017

In the last few decades, the sports world has seen the precipitous rise of data-driven player analysis methods across many professional sports. In light of these advents to the field, the current paper offers a novel application of a multi-criteria classification scheme developed within the scholarly literature, that being: grey relational analysis (GRA), to the milieu of professional sports. Specifically, this technique is utilized in the context of the National Basketball Association (NBA) to rank regular seasons during the Modern Era (i.e., since the 1979-80 season, after the merger between the NBA and ABA) through the use of a constellation of statistics. A sample of 100 seasons initially classified by player efficiency rating (PER) were examined using GRA. Findings from the present study illustrate that Stephen Curry’s recent MVP campaign during the 2015-16 season for the Golden State Warriors was the top ranked overall regular season out of those sampled in the Modern Era. The use of GRA is compared to current popular indicators for player evaluation and efficiency. Future directions and implications for professional sports are discussed.
Discovery of BiS2-Based Superconductor and Material Design Concept
Authors: Mizuguchi Yoshikazu
Published: January 2017

In 2012, we discovered new layered superconductors whose superconducting states emerge in the BiS2 layers. Since their crystal structure, composed of alternate stacks of BiS2 conduction layers and electrically insulating (blocking) layers, is similar to those of cuprate and Fe-based superconductors, many researchers have explored new BiS2-based superconductors and have studied the physical and chemical properties of the BiS2-based superconductors. In this paper, we present the histories of the discovery of the first BiS2-based superconductor, Bi4O4S3, and the second one, LaO1−xFxBiS2. The structural variation of the BiS2-based superconductor family is briefly introduced. Then, we show the material design concept for the emergence of bulk superconductivity in BiS2-based compounds. At the end, a possible strategy for the enhancement of the transition temperature in the BiS2-based superconductors is proposed.

Published: January 2017

The smart-grid concept takes the communications from the enclosed and protected environment of a substation to the wider city or nationwide area. In this environment, cyber security takes a key role in order to secure the communications. The challenge is to be able to secure the grid without impacting the latency while, at the same time, maintaining compatibility with older devices and non secure services. At the lower level, added security must not interfere with the redundancy and the latency required for the real-time substation automation communications. This paper studies how to integrate IEEE MAC Security standard (MACsec) in the substation environment, especially when used in substation system communications
Jun Dimerization Protein 2 Activates Mc2r Transcriptional Activity: Role of Phosphorylation and SUMOylation
Authors: Wang Chiung-Min , Wang Raymond , Liu Runhua , Yang Wei-Hsiung
Published: January 2017

Jun dimerization protein 2 (JDP2), a basic leucine zipper transcription factor, is involved in numerous biological and cellular processes such as cancer development and regulation, cell-cycle regulation, skeletal muscle and osteoclast differentiation, progesterone receptor signaling, and antibacterial immunity. Though JDP2 is widely expressed in mammalian tissues, its function in gonads and adrenals (such as regulation of steroidogenesis and adrenal development) is largely unknown. Herein, we find that JDP2 mRNA and proteins are expressed in mouse adrenal gland tissues. Moreover, overexpression of JDP2 in Y1 mouse adrenocortical cancer cells increases the level of melanocortin 2 receptor (MC2R) protein. Notably, Mc2r promoter activity is activated by JDP2 in a dose-dependent manner. Next, by mapping the Mc2r promoter, we show that cAMP response elements (between −1320 and −720-bp) are mainly required for Mc2r activation by JDP2 and demonstrate that −830-bp is the major JDP2 binding site by real-time chromatin immunoprecipitation (ChIP) analysis. Mutations of cAMP response elements on Mc2r promoter disrupts JDP2 effect. Furthermore, we demonstrate that removal of phosphorylation of JDP2 results in attenuated transcriptional activity of Mc2r. Finally, we show that JDP2 is a candidate for SUMOylation and SUMOylation affects JDP2-mediated Mc2r transcriptional activity. Taken together, JDP2 acts as a novel transcriptional activator of the mouse Mc2r gene, suggesting that JDP2 may have physiological functions as a novel player in MC2R-mediated steroidogenesis as well as cell signaling in adrenal glands.
Effects of Natural Products on Fructose-Induced Nonalcoholic Fatty Liver Disease (NAFLD)
Authors: Chen Qian , Wang Tingting , Li Jian , Wang Sijian , Qiu Feng , Yu Haiyang , Zhang Yi , Wang Tao
Published: January 2017

As a sugar additive, fructose is widely used in processed foods and beverages. Excessive fructose consumption can cause hepatic steatosis and dyslipidemia, leading to the development of metabolic syndrome. Recent research revealed that fructose-induced nonalcoholic fatty liver disease (NAFLD) is related to several pathological processes, including: (1) augmenting lipogenesis; (2) leading to mitochondrial dysfunction; (3) stimulating the activation of inflammatory pathways; and (4) causing insulin resistance. Cellular signaling research indicated that partial factors play significant roles in fructose-induced NAFLD, involving liver X receptor (LXR)α, sterol regulatory element binding protein (SREBP)-1/1c, acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), stearoyl-CoA desaturase (SCD), peroxisome proliferator–activated receptor α (PPARα), leptin nuclear factor-erythroid 2-related factor 2 (Nrf2), nuclear factor kappa B (NF-κB), tumor necrosis factor α (TNF-α), c-Jun amino terminal kinase (JNK), phosphatidylinositol 3-kinase (PI3K) and adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK). Until now, a series of natural products have been reported as regulators of NAFLD in vivo and in vitro. This paper reviews the natural products (e.g., curcumin, resveratrol, and (−)-epicatechin) and their mechanisms of ameliorating fructose-induced NAFLD over the past years. Although, as lead compounds, natural products usually have fewer activities compared with synthesized compounds, it will shed light on studies aiming to discover new drugs for NAFLD.
Key Issues of Interdisciplinary NEXUS Governance Analyses: Lessons Learned from Research on Integrated Water Resources Management
Authors: Hagemann Nina , Kirschke Sabrina
Published: January 2017

Governance has become a cornerstone in addressing complex linkages between multiple resources such as water, energy, and food. However, contributions of governance research in interdisciplinary research projects are either lacking or highly controversial. Drawing on Integrated Water Resources Management-related experiences of German research projects in emerging and developing countries, we demonstrate how to strengthen NEXUS-related governance analyses: There has to be a stronger focus on the analyses of existing and useful governance strategies as well as of conditions for governance transitions; governance analyses should refer to different types of problems, instead of only focusing on single cases and abstract analyses; and answers must be based on a more elaborate practice of inter- and transdisciplinary research. These suggestions should be implemented on the level of single researchers, but should also require incentives on an institutional level.

La réforme agraire sous la Seconde République espagnole (1931-1939)
Authors: Robledo Ricardo , Llecha Llop Canela
Published: January 2017

La réforme agraire, au même titre que les restructurations religieuse, militaire ou d’organisation territoriale, fut l’une des grandes mutations structurelles que les gouvernants républicains furent amenés à entreprendre au printemps 1931. Dans cet article, nous exposons brièvement certaines des opinions qui, hier comme aujourd’hui, ont remis en question l’utilité ou la nécessité de la réforme adoptée en septembre 1932. Nous indiquons deux moments bien distincts dans l’application de la réforme : la réforme dite éclairée qui, par le biais des terres expropriées des Grands d’Espagne, permit d’attribuer un lot à quelques milliers de paysans, et la réforme venue d’en bas , engagée à la faveur du changement politique que constitue la victoire du Front populaire en février 1936 – la surface octroyée aux paysans jusqu’au mois de juillet fut alors cinq fois plus importante que celle qui avait été distribuée au cours des trois années précédentes. Nous décrivons pour finir l’intensification de la réforme au début de la guerre civile, un processus qui la rend dès lors comparable aux réformes européennes contemporaines, et les problèmes qui ont découlé de l’affrontement avec les communistes chargés de conduire la politique de défense de la petite paysannerie face à l’hostilité des anarchistes et des autres forces politiques.

At present, recognition of micro-blog opinion leaders mainly depends on the number of users posting micro-blogs, registration time, the number of good friends and other static attributes. However, it is very difficult to obtain the ideal recognition results through the above mentioned methods. This paper puts forward a new method that identifies the opinion leaders according to the change of user features and outbreak nodes. Deeply analyzing various attributes and behaviors of users, on the basis of user features and outbreak nodes, user’s attribute features are regarded as the input variables, behavior features of the user and outbreak nodes are regarded as observed variables. The probability as an opinion leader is the latent variable between input variables and observation variables, and the constructed probability model is used to recognize micro-blog opinion leaders. Experiments are carried out on the two real-world datasets from Sina micro-blog and Twitter, and the comparative experimental results show that the proposed model can more precisely find the micro-blog opinion leaders.

Published: January 2017

Mobile Ad hoc Networks (MANETs) are considered as a reunion of wireless mobile devices (nodes) that form a temporary wireless network. In order to facilitate communication in MANET, every node has to participate in the routing process. Finding an optimal route is a fundamental task in MANET, where routes tend to be multi-hoped and susceptible. Several routing protocols exist and can be classified as; topology-based and position-based routing protocols. However, the efficiency of these protocols in highly dynamic and dense environments is a challenging task to be considered for increasing perceived Quality of Service (QoS) in MANET. This paper focuses on the presentation and basic operation of each category. A qualitative evaluation between both categories is conducted to achieve a performance comparison in terms of packet- delivery ratio, End-to End delay and routing overhead. Results show that position-based overcome topology-based routing protocols in high dynamic and sparse environments. Recommendations for designing and implementing efficient position-based protocols are presented.

Periodic fever with aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) is a relatively common autoinflammatory condition that primarily affects children. Although tendencies were reported for this syndrome, genetic variations influencing risk and disease progression are poorly understood. In this study, we performed next-generation sequencing for 82 unrelated PFAPA patients and identified a frameshift variant in the CARD8 gene (CARD8-FS). Subsequently, we compared the frequency of CARD8-FS carriers in our PFAPA cohort (13.9%) with a healthy local population group (3.2%) and found a significant association between the CARD8-FS polymorphism and risk for PFAPA syndrome (p = 0.012; odds ratio: 4.96 [95% confidence interval, 1.33–18.47]). Moreover, CARD8-FS carriers display a distinct PFAPA phenotype that is characterized by a higher prevalence of symptoms out of flares and oral aphthosis (both p = 0.02 compared with PFAPA patients without the frameshift variant). CARD8 encodes a protein component of the NLRP3 inflammasome, which plays an important role in inflammation and contributes to the pathology of various autoinflammatory diseases. We found that the CARD8-FS variant led to a truncated CARD8 protein lacking the FIIND and CARD domains. As a result, the mutant CARD8 protein lost the ability to interact with the NOD domain of NLRP3. In summary, these results identify a new CARD8 variant associated with PFAPA and further suggest that disruption of the interaction between CARD8 and NLRP3 can regulate autoinflammation in patients.
Sniffing out olfactory reference syndrome

Olfactory reference syndrome is characterised by the erroneous belief that one emits an unpleasant body odour. This results in significant distress and is often accompanied by repetitive behaviour such as frequent showering in an attempt to camouflage the perceived odour. The body odour concerns may have a delusional quality and do not respond to simple reassurance or counterexample. Herein, we report the case of an olfactory reference disorder (ORD) patient who had received multiple medical interventions and undergone polysurgery prior to an accurate diagnosis being established. ORD may lead to significant disability, yet often goes unrecognised for many years. For many patients, poor insight will contribute to their reluctance to consider psychiatric treatment. This case demonstrated that a multimodal treatment approach comprising judicious medication use, combined with cognitive behavioural therapy, in the context of a therapeutic alliance yielded therapeutic success.

In this paper we consider new perturbation bounds analysis of a kind of generalized saddle point systems. We provide perturbation upper bounds for the solutions of generalized saddle point systems, which extend the corresponding results in [W.-W. Xu, W. Li, New perturbation analysis for generalized saddle point systems, Calcolo., 46(2009), pp. 25-36] to more general cases.

О симплексах в графах диаметров в $\mathbb R^4$
Authors: Kupavskii Andrey Borisovich , Polyanskii Alexandr Andreevich
Published: January 2017

Граф $G$ является графом диаметров в $\mathbb R^d$,
если множество его вершин - это конечное подмножество
$\mathbb R^d$ диаметра $1$, а ребрами соединены пары
вершин на расстоянии единица. В этой работе мы показываем,
что в графе диаметров $G$ в $\mathbb R^4$, содержащем
полный подграф $K$ на $5$ вершинах, любой треугольник
должен иметь с $K$ общую вершину. В геометрической
интерпретации данное утверждение говорит следующее.
Пусть в $\mathbb R^4$ даны правильный единичный симплекс
на $5$ вершинах и правильный единичный треугольник. Тогда
либо они имеют общую вершину, либо диаметр объединения
множеств их вершин строго больше единицы.

Published: January 2017

Для алгебры $A$ через $V_A(n)$ обозначим размерность векторного
пространства, порожденного мономами длины не больше $n$.
Пусть $T_A(n)=V_A(n)-V_A(n-1)$. Назовем алгебру граничной,
если $T_A(n)-n<\mathrm{const}$. В работе описываются нормальные
базисы для алгебр с медленным ростом или граничных алгебр.
Пусть $\mathscr L$ - факторный язык над конечным
алфавитом $\mathscr A$. Функция роста $T_{\mathscr L}(n)$
есть число подслов длины $n$ в $\mathscr L$.
Мы также описываем факторные языки такие, что
$T_{\mathscr L}(n)\le n+\mathrm{const}$.

Об энергии Казимира в среде с дисперсией и поглощением в рамках подхода диагонализации Фано
Authors: Braun Mikhail Aleksandrovich
Published: January 2017

Энергия Казимира для электромагнитного поля в одномерном пространстве между двумя металлическими пластинами, заполненными диэлектриком с дисперсией и поглощением, вычислена в рамках микроскопического подхода, в котором среда моделируется набором осцилляторов с непрерывно распределенными частотами. Проанализирована трактовка сингулярных выражений, используемых в других работах, и показано, что при подходящем выборе калибровки и отбрасывании некоторых бесконечных членов результаты совпадают с теми, которые получаются при использовании подхода, где такие сингулярности отсутствуют. Изучено асимптотическое поведение на больших расстояниях, и сделан вывод, что оно всегда соответствует притяжению. Однако на конечных расстояниях влияние диэлектрика может приводить к отталкиванию.
Теория поля и анизотропия кубического ферромагнетика вблизи точки Кюри
Authors: Kudlis Andrei Yazepovich , Sokolov Aleksandr Ivanovich
Published: January 2017

Известно, что критические флуктуации могут изменять эффективную анизотропию кубического ферромагнетика вблизи точки Кюри. Если кристалл испытывает фазовый переход в орторомбическую фазу и его исходная анизотропия не слишком велика, эффективная анизотропия принимает в точке $T_{\mathrm c}$ универсальное значение $A^*=v^*/u^*$, где $u^*$ и $v^*$ - координаты кубической фиксированной точки уравнений ренормгруппы, входящие в скейлинговое уравнение состояния и в выражения для нелинейных восприимчивостей. C помощью метода псевдо-$\epsilon$-разложения найдено численное значение параметра анизотропии $A$ в критической точке. Суммирование по Паде шестипетлевых псевдо-$\epsilon$-разложений для $u^*$, $v^*$ и $A^*$ приводит к оценке $A^*=0.13\pm 0.01$, свидетельствующей о том, что обнаружение анизотропного критического поведения кубических ферромагнетиков в физических и компьютерных экспериментах является вполне возможным.

Authors: Afonin Sergei Sergeevich , Pusenkov Il'ya Valer'evich
Published: January 2017

Для описания высокотемпературной сверхпроводимости предложена голографическая модель с мягкой стенкой. По сравнению с уже существующими голографическими "боттом-ап" моделями сверхпроводников рассмотренный подход носит более феноменологический характер. С другой стороны, предложенная модель является математически более простой и имеет больше степеней свободы для описания проводимости реальных высокотемпературных сверхпроводников. Построены несколько примеров подобных моделей.

Черные дыры и частицы с нулевой и отрицательной энергией
Authors: Grib Andrei Anatol'evich , Pavlov Yurii Viktorovich
Published: January 2017

Исследуются свойства частиц с нулевой и отрицательной энергией и ненулевыми значениями проекции орбитального момента в эргосфере вращающейся черной дыры. Показано, что знак энергии частицы однозначно определяется угловой скоростью ее вращения в эргосфере. Приводится простое доказательство того факта, что экстремальные черные дыры не могут существовать. Исследован вопрос о возможности неограниченного роста энергии в системе центра масс двух сталкивающихся частиц, из которых одна или обе обладают отрицательной или нулевой энергией.
Критическое поведение $O(n)$-$\phi^4$-модели с антисимметричным тензорным параметром порядка: трехпетлевое приближение
Authors: Antonov Nikolai Viktorovich , Kompaniets Mikhail Vladimirovich , Lebedev Nikita Mikhailovich
Published: January 2017

Рассматривается критическое поведение $O(n)$-симметричной модели типа $\phi^4$ с антисимметричным тензорным параметром порядка. Согласно исследованию, проведенному ранее в однопетлевом приближении квантовой теоретико-полевой ренормгруппы, в модели присутствует ИК-притягивающая неподвижная точка и тем самым осуществляется ИК-скейлинг с универсальными показателями. C использованием более изощренного анализа, основанного на трехпетлевых вычислениях ренормгрупповых функций и борелевском конформном суммировании, показано, что ИК-поведение в действительности управляется другой неподвижной точкой уравнений ренормгруппы и, таким образом, модель принадлежит другому классу универсальности, нежели это можно предполагать на основе простейшего однопетлевого приближения. Достоверность полученных результатов остается тем не менее предметом обсуждения.
