The Quantum Hall Effect with Wilczek's charged magnetic flux tubes instead of electrons

Composites formed from charged particles and magnetic flux tubes, proposed by Wilczek, are one model for anyons - particles obeying fractional statistics. Here we propose a scheme for realizing charged flux tubes, in which a charged object with an intrinsic magnetic dipole moment is placed between two semi-infinite blocks of a high permeability ($\mu_r$) material, and the images of the magnetic moment create an effective flux tube. We show that the scheme can lead to a realization of Wilczek's anyons, when a two-dimensional electron system, which exhibits the integer quantum Hall effect (IQHE), is sandwiched between two blocks of the high-$\mu_r$ material with a temporally fast response (in the cyclotron and Larmor frequency range). The signature of Wilczek's anyons is a slight shift of the resistivity at the plateau of the IQHE. Thus, the quest for high-$\mu_r$ materials at high frequencies, which is underway in the field of metamaterials, and the quest for anyons, are here found to be on the same avenue.Comment: are welcom

Лексик семантического поля смерть в поэзии Есенина с точки зрения лингвостилистики

Sergej Aleksandrovič Esenin jedan je od najistaknutijih ruskih pjesnika dvadesetog stoljeća. Jedan od mnogih motiva koje je koristio u svom izričaju je bio motiv smrti ̶ ujedno jedan od najzastupljenijih motiva u umjetnosti uopće. Leksik semantičkog polja smrt pojavljuje se u svim fazama pjesnikova stvaralaštva, stoga se istraživačkim pristupom nastojalo iz lingvostilističke perspektive odrediti osnovne karakteristike svake faze (najzastupljenija vrsta riječi, kontekst u kojem se koristi svaka riječ, koliko se puta pojavljuje neka riječ i slično), kako bi se zaključno mogla utvrditi obilježja cijelog opusa vezana uz leksik semantičkog polja smrt. U prvoj fazi stvaralaštva prevladavaju imenice (najviše imenice smrt i grob), a broj istih opada tijekom sljedećih godina. U skladu s tim, tijekom treće i četvrte faze, Esenin počinje koristiti sve veći broj glagola, a naročito glagol umrijeti. U petoj fazi pojavljuje se najveći broj glagola, ali se ponovno, u gotovo jednakom broju kao i u prvoj fazi, pojavljuju i imenice. Za razliku od imenica i glagola, pridjevi nisu okarakterizirani kao frekventna vrsta riječi u ovom kontekstu, a to se odnosi na sve faze stvaralaštva. Tema koju je Esenin naročito volio i koristio je tema prirode i ruskog sela, odnosno njegov rodni kraj koji je napustio te mu se vraćao u svojim pjesmama. Upravo je ta tematika iznjedrila najveći broj riječi koje pripadaju semantičkom polju smrt. Na kraju, možemo reći da je Esenin uistinu mnogo upotrebljavao leksik semantičkog polja smrt i to tijekom svih godina stvaralaštva, a najviše u posljednjim godinama života. Sve u svemu, sa sigurnošću se može tvrditi da je smrt igrala važnu ulogu u poeziji Esenina te da je pronašla posebno mjesto među njegovim stihovima.Sergey Aleksandrovich Yesenin is one of the most prominent Russian poets of the 20th century. Many various leitmotifs appeared in his poetry, and one of the most noteworthy ones is the leitmotif of death, as well as it appears to be in all other forms of art. Lexical items denoting the semantic field of death can be found in all of Yesenin's poetic phases. Hence, the primary goal of this paper is to determine the main features of each phase from linguistic and stylisticpoint of view, based on the lexical items Yesenin used to signify the semantic field of death. Some of the elements which are regarded as the main features of a phase are the most frequently used parts of speech, the context in which each word is used, how many times the same word is repeated, etc. When it comes to Yesenin's poetic phases, an overall conclusion for all the phases can be made on the basis of an individual phase research. The first phase is dominated by nouns (especially death and grave), but their frequency lowers as the years pass. At the time of the third and the fourth stage, Yesenin starts to increase the use of verbs (especially die). The last – fifth – phase is characterized by the highest use of verbs, without neglecting a frequentuse of nouns again. During the entire creation period, Yesenin used adjectives much less than nouns and verbs to denote death. The main and favourite topics of Yesenin's poetry were nature and the Russian countryside and it is where he found a way to use the motif of death and to express it by various lexical items. It can be concluded that those lexical items denoting deathwere used to a large degree in all the phases, but especially in the last years of Yesenin's work. In the end, it can be safely said that death played a great role in Yesenin's poetry and found a very special place among his verses.Сергей Александрович Есенин является одним из самых известных имен русской литературы 20-ого века. Один из многих мотивов, которыми пользовался поэт в своих стихотворениях ̶ мотив смерти, один из важнейших и самых популярных мотивов искусства. Лексик семантического поля смерть, появившийся в свех поэтических этапах, исследован с точки зрения лингвостилистики, чтобы утвердить основные характерыстики каждой этапы (преобладающая часть речи, контекст использования каждого слова, сколько раз повтораются те же самые слова и тому подобное) и потом прийти к выводу всех этапах вместе. В первой этапе преобладают сушествительные (особенно смерть и могила), использование которых уменьшается в течении следующих лет. Во время третьей и четвертой этапы, Есенин начинает использовать более глаголов (особенно умереть). В пятой этапе является самое большоеколичество, но возвращается так же и к использованию имен сушествительных почти так часто, как в первой этапе. Имена прилагательные появляются гораздо меньше ̶ иногда в роли атрибута, но чаще атрибутами являются «обычные» имена прилагательных. Тема, которую Есенин особенно любил ̶ природа и русская деревня, его родной край. Именно в такиих стихотворениях исопользовал наибольшее количество слов семантического поля смерть. В конце, можно утвердить что Есенин дествительно много занимался лексиком семантического поля смерть и что этим занимался в течении всего творества, но главным образом в последние годы своей жизни. Все-таки, оказалось, что лексик семантического поля смерть имеет особенное место в поэзии Есенина

Protection of sugar beet pests and diseases on the OPG Kesegić in 2014.

U 2013. godini pregledalo se tlo na OPG-u Kesegić. Pregled se obavljao na prisustvo žičnjaka, grčica običnog hrušta, repinog buhača i repine pipe. Brojnost štetnika koja se utvrdila za žičnjake iznosila je 0,4 žičnjaka po m², a grčice običnog hrušta nisu utvrđene. Brojnost štetnika koja se utvrdila za repinu pipu iznosila je 0,1 pipu po m². Prilikom pregleda tla nije utvrđena prisutnost sovica. Tijekom vegetacije pratila se pojava bolesti i štetnika vizulnim pregledom biljaka. Prilikom pregleda utvrdilo se prisustvo repine pipe s prosječno 0,1 pipom po m² i repinog buhača gdje je utvrđena prosječno 1 grizotina po biljci u stadiju razvoja pravog lišća. Utvrđena brojnost štetnika nije prelazila pragove štetnosti i nije bilo nužno tretirati. Tijekom lipnja uočili smo simptome Cercospore beticole na više od 5 % biljka. Prvo tretiranje izvršeno je 26.06.2014. sa pripavakom Amistar Extra. Prvo tretiranje sa preparatom Amistar extra nije se pokazalo uspješno te su obavljena još dva tretiranja u terminima 19.07.2014. i 13.08.2014. Nakon provedena sva tri tretmana bolest se uspješno suzbila.The soil at the family farm Kesegić was analyzed in 2013. The soil was examined for the presence of wireworms, cockchafers, pyrethrum and sugar beet weevil. The number of pests found for wireworms was 0.4 wireworms per square meter while the presence of cockchafers was not determined. The number of pests found for sugar beet weevil was 0.1 per square meter. The soil did not contain moths during the examination. The appearance of diseases and pests was monitored during the growing season by visual review of the plants. The examination determined the presence of sugar beet weevil with an average 0.1 per square meter and presence of pyrethrum with an average of 1 bite per plant in the development stage of real leaves. Determined number of pests did not exceed the threshold and it was not necessary to treat them. During the examination in June we have also noticed the symptoms of Cercospora beticola in more than 5% of the plants. The first treatment was conducted on June 26, 2014., with usage of Amistar Extra preparation. The first treatment with Amistar Extra preparation did not prove to be successful and additional two treatments were conducted on July 19 and August 13, 2014. After all three treatments the disease was successfully suppresse

Health-Related Concepts and Cognitive Linguistics

Human behavior is governed by concepts. Concepts are cognitive representations of reality. Cognitive linguistics suggests that there are cognitive models affecting the formation of concepts in human mind, such as cognitive metaphor and a prototype model. We used the example of an ancient procedure – trepanation in order to show the connection between the procedure and the concept of the skull as a container, which is a metaphor. Most important concepts in medical systems are health and disease. There is no agreement about their exact definition, although there have been many studies focusing on that. Based on the previous research, we suggest possible benefits from approaching the disease as a prototype category. In all studies so far there have always been consistencies in rating entities qualifying as a disease which is a feature of a prototype category – membership gradience. Entities perceived as diseases by respondents in studies so far have not been the same, but they share certain features. It is more likely for an entity to be considered a disease if it can lead to death, for example. In our opinion there are common core features determining disease as a cognitive category. Further cross-cultural studies could answer what features an entity needs to have in order to be considered a disease.Stressing such features could improve patients’cooperation when a new disease appears

EJACULATORY DYSFUNCTION IN PATIENT WITH SCHIZOPHRENIA ON SERTINDOLE

The antipsychotic drugs can be of great benefit for the wide range of psychotic disorders, but all are associated with various adverse effects. Patients with psychotic disorder consider the sexual dysfunction to be among the most important side effects. Although, it is not uncommon for the patients with schizophrenia to report the sexual dysfunction, patients with untreated schizophrenia have fewer dysfunctions compared to those on antipsychotic medication. The decision whether the current treatment with a prolactin-increasing antipsychotic or sexual dysfunction inducing drug should be continued or switched to another antipsychotic drug, has to be made on the basis of the patient\u27s risk-benefit estimation. It has to be kept on mind that adverse effects are usually dose dependent. In this case report, sertindole treated patient with chronic schizophrenia developed sexual side effect manifested as ejaculatory dysfunction that was significantly ameliorated by drug-dose reduction

Berry phase for a Bose gas on a one-dimensional ring

We study a system of strongly interacting one-dimensional (1D) bosons on a ring pierced by a synthetic magnetic flux tube. By the Fermi-Bose mapping, this system is related to the system of spin-polarized non-interacting electrons confined on a ring and pierced by a solenoid (magnetic flux tube). On the ring there is an external localized delta-function potential barrier $V(\phi)=g \delta(\phi-\phi_0)$. We study the Berry phase associated to the adiabatic motion of delta-function barrier around the ring as a function of the strength of the potential $g$ and the number of particles $N$. The behavior of the Berry phase can be explained via quantum mechanical reflection and tunneling through the moving barrier which pushes the particles around the ring. The barrier produces a cusp in the density to which one can associate a missing charge $\Delta q$ (missing density) for the case of electrons (bosons, respectively). We show that the Berry phase (i.e., the Aharonov-Bohm phase) cannot be identified with the quantity $\Delta q/\hbar \oint \mathbf{A}\cdot d\mathbf{l}$. This means that the missing charge cannot be identified as a (quasi)hole. We point out to the connection of this result and recent studies of synthetic anyons in noninteracting systems. In addition, for bosons we study the weakly-interacting regime, which is related to the strongly interacting electrons via Fermi-Bose duality in 1D systems

Secular Changes in Growth and Obesity in Perinatal Population

The survey was conducted during the last 25 years and included 2414 healthy women who delivered in »Sestre milosrdnice« University Hospital Center in Zagreb, Croatia and their newborns. The aim was to establish the secular trend of some anthropological factors through two generations. Anthropological features such as pre-pregnancy weight, body mass index before pregnancy, height, age, place of residence, educational level, parity and the newborn weight were registered. The study was randomized. The mothers from the city of Zagreb and the surrounding villages, rural areas are examined. The women age was different and also different levels of education and socioeconomic status. The study included women who had not given birth yet, who had delivered once, twice, and three or more times. Maternal height in 25 years increased by 3.1cm. and increases with education. The pre-pregnancy weight increased 2.8 kg and increases with age, parity and rural life. The body mass index (BMI) which the women had before pregnancy was calculated, and according to its value the participants were divided in three groups: with normal weight, overweight and fat. Among the studied periods BMI does not differ significantly, but does differ significantly with respect to the ordinal number of births, parity, age and living environment. Higher BMI was associated with deliveries to heavier children
