description: Der technische Wandel schreitet rasant voran und aktuell sind wir mitten im wichtigsten Wandel, der Digitalisierung. Die Onlineberatung ist mit den neuen digitalen Medien und dem Internet im stetigen Wandel und bisher kaum erforscht. Die Onlineberatung bietet einige Möglichkeiten, Beratungen virtuell zu führen und so Klient*innen einen weiteren Zugang zu Angeboten der Sozialen Arbeit zu ermöglichen. Die Soziale Arbeit berät ihre Klient*innen klassisch, in einem face-to-face Setting. Wie können Sozialarbeitende demnach die neuen Möglichkeiten der Onlineberatung und digitalen Medien in die Praxis umsetzen? Die Autorin geht der Frage nach, welche Gemeinsamkeiten und Unterschiede es bei der klassischen Beratung und der Onlineberatung gibt und welche Vorteile sie darin erkennt. Die Digitalisierung und die digitalen Medien sind auch im Alltag von Kindern und Jugendlichen sehr präsent. Schulen greifen diese Thematik im Unterricht auf und befähigen und begleiten die Kinder und Jugendlichen im Umgang damit. Die Autorin arbeitet in der Schulsozialarbeit und sieht in diesem Alltag eine neue Chance. Die Schulsozialarbeit ist ein freiwilliges und niederschwelliges Angebot innerhalb der Schule. Sie arbeitet vor Ort und ist nah am Alltag der Schüler*innen. Sie bietet Unterstützung und Beratung für Schüler*innen, deren Eltern und Erziehungsberechtigte sowie für Lehrpersonen bei persönlichen und sozialen Problemen. Die vorliegende Arbeit zeigt auf, welche Methoden und Ansätze sich in der Schulsozialarbeit bewähren und dass diese auch für die Onlineberatung übernommen werden können.

description: Статья посвящена рассмотрению вопросов, связанных с управлением запасами торговой организации, работающей в сфере цветочного бизнеса. Управление запасами является одним из ключевых аспектов повышения эффективности деятельности организаций торговли, т.к., с одной стороны, торговый бизнес не может функционировать без запасов, а с другой – доля торговых запасов на предприятиях торговли составляет порядка половины всех его оборотных активов, т.е. существует угроза замораживания финансовых ресурсов предприятия, а, следовательно, потери эффективности работы. В статье выделены объективные причины создания запасов в торговой организации, особенно в цветочном бизнесе: неравномерность и трудная прогнозируемость спроса на цветочную продукцию; возможность нарушения графика поставки свежих цветов, особенно в отношении зарубежных поставок; необходимость моментального обслуживания клиентов, что во многом определяет конкурентоспособность фирмы, а в цветочном бизнесе время играет особую роль ввиду короткого срока годности продукции; возможность получения скидки за больший объем партии (многие поставщики делают скидки своим постоянным покупателям за увеличение объемов партии).
An experimental study of the plant-arthropod-bird food chain in the southwestern Yukon
Creators: name: Folkard, Nicholas Francis Goring
Publisher: name: University of British Columbia

description: I describe an experimental study of the importance of food limitation and predation at three trophic levels in a terrestrial food web. The study system was the herb layer vegetation - arthropod - insectivorous bird food chain in the boreal forest near Kluane Lake, southwestern Yukon. Since little is known about boreal bird communities, I conducted a descriptive study of the community of passerine and piciform birds at Kluane in addition to the main study. Variable circular plot point counts were used to estimate bird populations in 1987 through 1990. Species' habitat preferences, use of foraging substrates and diets were studied in 1988 and 1989. Population densities, species richness and evenness were all low. Yellow-rumped warblers (Dendroica coronata) and dark-eyed juncos (Junco hyemalis) dominated the community. Common species differed markedly in their habitat preferences, and showed generally low overlaps in their use of foraging substrates. There was little evidence of dietary specialization. There was rather little spatial variation in the community, and species composition and total density remained approximately the same through time. However, there were large fluctuations in some species' populations between 1987 and 1989. The experimental study was conducted at two scales. Chemical fertilizer was applied to two 570m x 570m areas in 1987, 1988 and 1989. I compared arthropod populations, bird populations and bird reproductive performance in these areas with those in two control areas. Two experiments using 5m x 5m plots were performed in 1988 to examine the effects of fertilization on plants and arthropods in more detail, and to study the responses of these trophic levels to the exclusion of passerine birds and mammalian herbivores. All three trophic levels responded positively to fertilization, but the results were variable and there were no very large increases in biomass or population size. Dark-eyed juncos nested one week earlier in fertilized areas, which may have enhanced their reproductive success. Passerine exclusion did not increase arthropod biomass, but exclusion of mammalian herbivores increased plant biomass. "Bottom-up" limitation by food appears to dominate this system, but "top-down" limitation also operates at at least one level. More work is needed to fully understand how the system functions.
Characterizing the local double white dwarf population

description: The characterization of the local double white dwarf (DWD) population is crucial to our understanding of multiple questions, from stellar evolution, through the progenitors of Type-Ia supernovae (SNe Ia), to gravitational wave sources. From a spectroscopic sample of 439 WDs from the SPY survey, we measure the maximal changes in radial-velocity (DRVmax) between epochs, and model the observed DRVmax statistics via Monte-Carlo simulations, to constrain the population characteristics of DWDs. We then combine the results with those of a complementary sample from the SDSS to obtain new and precise information on the DWD population and on its gravitational-wave-driven merger rate. We find that ~10% of WDs are in DWD systems in the separation range ~<4 AU within which the data are sensitive to binarity. The Galactic WD merger rate per WD is ~1e-11 per year. Integrated over the Galaxy lifetime, this implies that 8.5-11% of all WDs ever formed have merged with another WD. If most DWD mergers end as more-massive WDs, then some ~10% of WDs are DWD-merger products. The implied Galactic DWD merger rate is 4.5-7 times the Milky Way’s specific SN Ia rate. If most SN Ia explosions come about from the mergers of some DWDs then ~15% of all WD mergers must lead to a SN Ia.

description: A new dark energy model, named as ``agegraphic dark energy'', has been proposed by one of us (R. G. Cai) in arXiv:0707.4049, based on the Károlyházy uncertainty relation, which arises from the quantum mechanics together with general relativity. Then, in arXiv:0707.4052, it has been extended by including the interaction between the agegraphic dark energy and the pressureless (dark) matter. In this note, we investigate the agegraphic dark energy models without and with interaction by means of statefinder diagnostic and w-w' analysis.

description: The specific heat is frequency dependent in highly viscous liquids. By solving the full one-dimensional thermo-viscoelastic problem analytically it is shown that, because of thermal expansion and the fact that mechanical stresses relax on the same time scale as the enthalpy relaxes, the plane thermal-wave method does not measure the isobaric frequency-dependent specific heat c_p(omega). This method rather measures a "longitudinal" frequency-dependent specific heat, a quantity defined and detailed here that is in-between c_p(omega) and c_v(omega). This result means that no wide-frequency measurements of c_p(omega) on liquids approaching the calorimetric glass transition exist. We briefly discuss consequences for experiment.

description: We investigate the effect of feedback delay on the outage probability of multiple-input single-output (MISO) fading channels. Channel state information at the transmitter (CSIT) is a delayed version of the channel state information available at the receiver (CSIR). We consider two cases of CSIR: (a) perfect CSIR and (b) CSI estimated at the receiver using training symbols. With perfect CSIR, under a short-term power constraint, we determine: (a) the outage probability for beamforming with imperfect CSIT (BF-IC) analytically, and (b) the optimal spatial power allocation (OSPA) scheme that minimizes outage numerically. Results show that, for delayed CSIT, BF-IC is close to optimal for low SNR and uniform spatial power allocation (USPA) is close to optimal at high SNR. Similarly, under a long-term power constraint, we show that BF-IC is close to optimal for low SNR and USPA is close to optimal at high SNR. With imperfect CSIR, we obtain an upper bound on the outage probability with USPA and BF-IC. Results show that the loss in performance due to imperfection in CSIR is not significant, if the training power is chosen appropriately.

description: The eigenfunctions of nested wells with incommensurate boundary geometry, in both hydrodynamic shallow water regime and quantum cases, are systematically and exhaustively studied in this letter. The boundary arrangement of the nested wells consist of polygonal ones, square or hexagonal, with a concentric immersed similar but rotated well or plateau. A rich taxonomy of wave patterns, such as quasicrystalline states, their crystalline rational approximants and some other exotic but well known tilings, is found in these mimicked experiments. To our best knowledge, these hydrodynamic rational approximants are presented here for the first time in a hydrodynamic-quantum framework. The corresponding statistical nature of the energy level spacing distribution reflects this taxonomy by changing the spectral types.

description: В настоящее время гражданское законодательство Республики Беларусь развивается в условиях перехода экономики на шестой технологический уклад. В результате всеобщей цифровизации в гражданский оборот вводятся
все новые объекты правоотношений, правовая природа которых носит неоднозначный характер. Для определения правового статуса таких объектов и внедрения новых технологий во все сферы жизнедеятельности человека в
Республике Беларусь был принят ряд нормативных правовых актов, основным из которых следует признать Декрет Президента Республики Беларусь от 21 декабря 2017 г. №8 «О развитии цифровой экономики» (далее – Декрет №8).
Декрет №8 призван стать основой для последующего развития цифровых технологий на территории белорусского государства. Однако, несмотря на положительные результаты принятия указанного нормативного правового
акта, отдельные его положения требуют уточнения. Речь идет о таких основополагающих понятиях, как «токен» и «криптовалюта». По мнению автора статьи, содержащиеся в Декрете №8 определения не позволяют в
достаточной степени выявить правовую природу указанных средств обмена, а, значит, определить их место среди объектов гражданских прав. Не опровергая наличие у токена вещно-правовой природы, автор делает вывод о
необходимости реформирования подходов к определению объекта вещных прав. Кроме этого, автор указывает на спорный характер приравнивания понятия «криптовалюта» к понятию «токен», поскольку на основании проведенного исследования им были выявлены значительные отличия, которые не
позволяют говорить о них как о синонимах.

description: This is the first paper in a series (of four) designed to show how to use geometric algebras of multivectors and extensors to a novel presentation of some topics of differential geometry which are important for a deeper understanding of geometrical theories of the gravitational field. In this first paper we introduce the key algebraic tools for the development of our program, namely the euclidean geometrical algebra of multivectors Cl(V,G_{E}) and the theory of its deformations leading to metric geometric algebras Cl(V,G) and some special types of extensors. Those tools permit obtaining, the remarkable golden formula relating calculations in Cl(V,G) with easier ones in Cl(V,G_{E}) (e.g., a noticeable relation between the Hodge star operators associated to G and G_{E}). Several useful examples are worked in details fo the purpose of transmitting the "tricks of the trade".

description: The LHCb experiment will operate for about five years at a luminosity of 2x10^32 cm^-2 s^-1 and plans are to accumulate a data sample of ~10 fb^-1. Here we present the physics programme and detector design for a future high luminosity phase of the LHCb experiment. An upgraded LHCb experiment would operate at ten times the design luminosity, i.e. at ~2x10^33 cm^-2 s^-1 and aims to collect a data sample of ~100 fb^-1 over five years. This programme would allow the probe of new physics at an unprecedented level. Key measurements include the B^0_s mixing phase phi_s in B^0_s -> J/ψphi and B^0_s -> phi phi decays with a significant sensitivity to the small Standard Model prediction and a very precise measurement of the CKM angle gamma in tree diagram decays. Initial studies of the modified LHCb trigger and detectors are presented. The upgraded LHCb experiment can run with or without an LHC luminosity upgrade.

description: Антимонопольное регулирование – одна из форм государственного регулирования экономики, представляющая комплекс антимонопольных мер и механизмов их реализации. В разных странах антимонопольное
регулирование имеет свои отличия и акценты, что связано с особенностями развития и функционирования национальных экономик. При государственном регулировании экономики ставится широкий спектр задач: они могут касаться цен, доходов, распределения прибыли, изменения макроэкономических показателей и т.д. Изучение хронологии развития антимонопольного регулирования позволяет выделить несколько этапов его становления, каждый
из которых имеет свое историческое место, содержание и тактику реализации политики. В Республике Беларусь развитие антимонопольного регулирования осуществлялось в несколько этапов. Создание единой самостоятельной
централизованной системы антимонопольного органа в Республике Беларусь обусловлено необходимостью защиты добросовестной конкуренции, создания цивилизованных и эффективных инструментов контроля ценообразования.
Анализ и обобщение опыта реализации антимонопольного регулирования в развитых странах позволяет выделить такие основные его цели как нейтрализация монополистической власти и различных форм ее проявления,
создание условий для развития добросовестной конкуренции, повышение общественного благосостояния, обеспечение устойчивого экономического роста. Основными принципами антимонопольного регулирования являются
недопущение устранения конкуренции органами власти, использование ими принципа разумного подхода при применении норм антимонопольного законодательства, контроль за процессами концентрации, законность, гласность и публичность в действиях антимонопольных органов, содействие формированию рыночных отношений на основе развития конкуренции и предпринимательства.

description: Mid-infrared diagnostics are presented for a large portion of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample plus archival data from the Infrared Space Observatory and the Spitzer Space Telescope. Our main result is that these mid-infrared diagnostics effectively constrain a target's dominant power source. The combination of a high ionization line index and PAH strength serves as an efficient discriminant between AGN and star-forming nuclei, confirming progress made with ISO spectroscopy on starbursting and ultraluminous infrared galaxies. The sensitivity of Spitzer allows us to probe fainter nuclei and star-forming regions within galaxy disks. We find that both star-forming nuclei and extranuclear regions stand apart from nuclei that are powered by Seyfert or LINER activity. In fact, we identify areas within four diagnostic diagrams containing >90% Seyfert/LINER nuclei or >90% HII regions/HII nuclei. We also find that, compared to starbursting nuclei, extranuclear regions typically separate even further from AGN, especially for low-metallicity extranuclear environments. In addition, instead of the traditional mid-infrared approach to differentiating between AGN and star-forming sources that utilizes relatively weak high-ionization lines, we show that strong low-ionization cooling lines of X-ray dominated regions like [SiII] 34.82 micron can alternatively be used as excellent discrimants. Finally, the typical target in this sample shows relatively modest interstellar electron density (~400 cm^{-3}) and obscuration (A_V ~ 1.0 mag for a foreground screen), consistent with a lack of dense clumps of highly obscured gas and dust residing in the emitting regions.

description: A light scalar field, minimally or not-minimally coupled to the metric field, is a well-defined candidate for the dark energy, overcoming the coincidence problem intrinsic to the cosmological constant and avoiding the difficulties of parameterizations. We present a general description of the weak gravitational lensing valid for every metric theory of gravity, including vector and tensor perturbations for a non-flat spatial metric. Based on this description, we investigate two minimally-coupled scalar field quintessence models using VIRMOS-Descart and CFHTLS cosmic shear data, and forecast the constraints for the proposed space-borne wide-field imager DUNE.

description: Given a holomorphic vector bundle $\cale$ on a connected compact complex manifold X, [FLS] construct a $\compl$-linear functional $I_{\cale}$ on $\hh{2n}{\compl}$. This is done by constructing a linear functional on the 0-th completed Hochschild homology $\choch{0}{(\dif(\cale))}$ of the sheaf of holomorphic differential operators on $\cale$ using topological quantum mechanics. They show that this functional is $\int_X$ if $\cale$ has non zero Euler characteristic. They conjecture that this functional is $\int_X$ for all $\cale$. A subsequent work [Ram] by the author proved that the linear functional $I_{\cale}$ is independent of the vector bundle $\cale$. This note builds upon the work in [Ram] to prove that $I_{\cale}=\int_X$ for an arbitrary holomorphic vector bundle $\cale$ on an arbitrary connected compact complex manifold X. This is done using an argument that is very natural from the geometric point of view. This argument enables us to extend the construction in [FLS] to a construction of a linear functional $I_{\cale}$ on $\text{H}^{2n}_{c}(Y,\compl)$ for an arbitrary holomorphic vector bundle $\cale$ on an arbitrary connected complex manifold Y and prove that $I_{\cale} = \int_Y$. We also generalize a result of [Ram] pertaining to "cyclic homology analogs" of $I_{\cale}$.

description: Одним из неотъемлемых условий эффективного функционирования экономики в национальном масштабе является высокий уровень развития рынка коммерческой недвижимости, что во многом способствует реализации одного
из основных принципов рыночной экономики – индивидуальной обособленности и свободы хозяйственной деятельности экономических агентов. В статье обоснована роль государства как основного субъекта регулирования рынка недвижимости и, в частности, изучено состояние правового обеспечения государственной регистрации объектов коммерческой недвижимости в Республике Беларусь. В соответствии с авторским понятием «рынок коммерческой недвижимости», выделенными особенностями этого рынка введено понятие «субъектная структура рынка коммерческой недвижимости», которая сформирована с позиции объединения разнофункциональных субъектов рынка коммерческой недвижимости, учитывая систему взаимоотношений между ними, обобщающая их цели, задачи, экономические интересы, способы и формы организации и взаимодействия по поводу движения объектов коммерческой недвижимости на разных стадиях жизненного цикла. Идентифицирован каждый элемент из пяти блоков субъектной структуры рынка коммерческой недвижимости Республики Беларусь. Дано понятие «механизм государственного регулирования рынка недвижимости». Выделены методы прямого административного и экономического регулирования рынка коммерческой недвижимости. Показана система государственных организаций в области государственной регистрации в Республике Беларусь. Рассмотрена система государственной регистрации объектов недвижимости в Республике Беларусь, конкретизированы ее цели. Проведенный анализ действующей системы государственной регистрации позволил выявить ее недостатки, что выступило основанием разработки направлений совершенствования процесса, в том числе с использованием ГИС-технологий. Обоснована необходимость введения инновационного инструмента – технико-экономического единого паспорта объекта коммерческой недвижимости.
Ovarian activity in postpartum, early pregnant and norgestomet synchronized dairy cattle

description: Studies to monitor bovine ovarian function with regard to follicular growth and turnover, and corpus luteum (CL) growth and function, were carried out during three different reproductive states: the postpartum anestrus period, early pregnancy and during the artificial control of the estrous cycle with the synthetic progestin norgestomet. Ovarian function was monitored using a combination of ultrasound imaging and progesterone (P₄) profiling. Growth of large antral follicles (> 10mm) was found to commence very early in the postpartum period and ovulation occurred as early as the first week postpartum. Short first postpartum estrous cycles (< 18 days) were observed in a minority of the animals studied (4/10) and the occurance of a short first cycle was not associated with an early ovulation following parturition. Growth of large antral follicles occurred in a wave-like pattern during the postpartum estrous cycles with most cycles being composed of two waves of growth, the second wave resulting in the growth of the ovulatory follicle. A wave-like pattern of growth of large dominant follicles was also seen through the first 60 days of pregnancy. There was no difference between pregnant and non pregnant cows in the size of the dominant follicle found on day 20. In addition no effect of the CL could be found on the side on which the dominant follicle was found, it was as likely to be on the ipsilateral ovary to the CL as on the contra lateral. The gonadotrophin ihibitor norgestomet did not effect follicular dynamics in the presence of the CL, however in the absence of a CL the dominant follicle present was maintained for the duration of the norgestomet treatment and then went on to ovulate upon norgestomet removal. In addition there was no new growth of antral follicles in the absence of a CL. Norgestomet did not effect the temporal relationship between the onset of standing estrus, the LH surge and ovulation. The results of the three studies suggest that a wavelike pattern of growth of large antral follicles is a characteristic of the bovine ovary regardless of the reproductive state.

description: We present models of decaying particles for increasing the effective number of neutrinos N_nu after big bang nucleosynthesis but before the structure formation begins. We point out that our scenario not only solves the discrepancy between the constraints on N_nu from these two epochs, but also provides a possible answer to deeper inconsistency in the estimation of the matter power spectrum amplitude at small scales, represented by sigma_8, between the WMAP and some small scale matter power measurements such as the Lyman-alpha forest and weak lensing. We consider (a) saxion decay into two axions; (b) gravitino decay into axino and axion; (c) Dirac right-handed sneutrino decay into gravitino and right-handed neutrino.

description: We investigate the interplay between spin and orbital correlations in monolayer and bilayer manganites using an effective spin-orbital t-J model which treats explicitly the e_g orbital degrees of freedom coupled to classical t_{2g} spins. Using finite clusters with periodic boundary conditions, the orbital many-body problem is solved by exact diagonalization, either by optimizing spin configuration at zero temperature, or by using classical Monte-Carlo for the spin subsystem at finite temperature. In undoped two-dimensional clusters, a complementary behavior of orbital and spin correlations is found - the ferromagnetic spin order coexists with alternating orbital order, while the antiferromagnetic spin order, triggered by t_{2g} spin superexchange, coexists with ferro-orbital order. With finite crystal field term, we introduce a realistic model for La_{1-x}Sr_{1+x}MnO_4, describing a gradual change from predominantly out-of-plane 3z^2-r^2 to in-plane x^2-y^2 orbital occupation under increasing doping. The present electronic model is sufficient to explain the stability of the CE phase in monolayer manganites at doping x=0.5, and also yields the C-type antiferromagnetic phase found in Nd_{1-x}Sr_{1+x}MnO_4 at high doping. Also in bilayer manganites magnetic phases and the accompanying orbital order change with increasing doping. Here the model predicts C-AF and G-AF phases at high doping x>0.75, as found experimentally in La_{2-2x}Sr_{1+2x}Mn_2O_7.

description: We report the discovery of the partially eclipsing binary LP 133-373. Nearly identical eclipses along with observed photometric colors and spectroscopy indicate that it is a pair of chromospherically active dM4 stars in a circular 1.6 d orbit. Light and velocity curve modeling to our differential photometry and velocity data show that each star has a mass and radius of 0.340+/-0.014 M_sun and 0.33+/-0.02 R_sun. The binary is itself part of a common proper motion pair with LP 133-374 a cool DC or possible DA white dwarf with a mass of 0.49-0.82 M_sun, which would make the system at least 3 Gyr old.

description: THis is a poster presented at the 2024 Annual MIDAS meeting held at the Henry Royce Institute, University of Manchester, on the 16th of September 2024.

The poster covers a study looking a tthe impact of pre-existing cracks on the corrosion performance of chromium coated zirconium alloy cladding tubes.

Cracks were introduced to the coating by mehcanical deforming cladding tubes under uniaxial tension in the axial direction up to a strain of 2%. Four different coatings candidtates were exmained including a Nitrogen Cold Spray (NCS) and three differnt Magnetron Sputtered Physical Vapour Deposited (MS-PVD) coatings, labeled PVD a, b and c. PVDa and b had been produced using the same susbtrate bias but with different coating thicknesses, whilst PVD c was produced at a different substrate bias. 

The samples were autoclaved in pressurised water reactor (PWR) chemistry at 360 degrees celcius for 25 days with a subsequent autoclave test performed at the same temperature and with the same chemistry but using deuterium spiked water for 28 days.

The samples were then cross sectioned to reveal the circumferential cracks and were imaged using electorn microscopy to analyse crack density, crack opening and oxide area.

The cross sectioned samples were anaylsed using NanoSIMS to invesitgate the relative location of Deuterium within the microstrucutre as a result of the second autoclave tests. 

The coatings demonstrated enhanced oxidation resistance compared to the uncoated cladding. While larger oxides can lead to blistering and increase the risk of delamination, they are typically associated with large crack openings in PVD coatings. A  reduced crack density can lead to fewer cracks with a greater cack opening that allow for larger oxide formation, whereas higher crack densities contribute to a greater overall area of oxide islands at the Cr-Zr interface. The complex crack networks observed in NCS coatings, however, appear to reduce oxide size and limit deuterium presence at the interface.

description: We have created a general methodology for calculating the wavelength-dependent light curves of close-in extrasolar giant planets (EGPs) as they traverse their orbits. Focussing on the transiting EGPs HD189733b, TrES-1, and HD209458b, we calculate planet/star flux ratios during secondary eclipse and compare them with the Spitzer data points obtained so far in the mid-infrared. We introduce a simple parametrization for the redistribution of heat to the planet's nightside, derive constraints on this parameter (P_n), and provide a general set of predictions for planet/star contrast ratios as a function of wavelength, model, and phase. Moreover, we calculate average dayside and nightside atmospheric temperature/pressure profiles for each transiting planet/P_n pair with which existing and anticipated Spitzer data can be used to probe the atmospheric thermal structure of severely irradiated EGPs. We find that the baseline models do a good job of fitting the current secondary eclipse dataset, but that the Spitzer error bars are not yet small enough to discriminate cleanly between all the various possibilities.

description: We consider $N$-wave type equations related to the orthogonal algebras obtained from the generic ones via additional reductions. The first $\mathbb{Z}_2$-reduction is the canonical one. We impose a second $\mathbb{Z}_2$-reduction and consider also the combined action of both reductions. For all three types of $N$-wave equations we construct the soliton solutions by appropriately modifying the Zakharov-Shabat dressing method. We also briefly discuss the different types of one-soliton solutions. Especially rich are the types of one-soliton solutions in the case when both reductions are applied. This is due to the fact that we have two different configurations of eigenvalues for the Lax operator $L$: doublets, which consist of pairs of purely imaginary eigenvalues, and quadruplets. Such situation is analogous to the one encountered in the sine-Gordon case, which allows two types of solitons: kinks and breathers. A new physical system, describing Stokes-anti Stokes Raman scattering is obtained. It is represented by a 4-wave equation related to the ${\bf B}_2$ algebra with a canonical $\mathbb{Z}_2$ reduction.

description: Quasi-stationary (i.e. parametric) transitions from rotating equilibrium configurations of fluid bodies to rotating black holes are discussed. For the idealized model of a rotating disc of dust, analytical results derived by means of the "inverse scattering method" are available. They are generalized by numerical results for rotating fluid rings with various equations of state. It can be shown rigorously that a black hole limit of a fluid body in equilibrium occurs if and only if the gravitational mass becomes equal to twice the product of angular velocity and angular momentum. Therefore, any quasi-stationary route from fluid bodies to black holes passes through the extreme Kerr solution.

description: A self-trapped Bose-Einstein condensate is shown to be stabilized in two-dimensional free space by Rabi oscillations between two hyperfine states which make an effective interatomic interaction oscillate in time. The stabilization mechanism is elucidated by using a two-component Gross-Pitaevskii equation combined with a variational analysis. The parameter regime of stability is investigated.

description: The possibility of a new type of computing, where thermal noise is the information carrier and the clock in a computer, is studied. The information channel capacity and the lower limit of energy requirement/dissipation are studied in a simple digital system with zero threshold voltage, for the case of error probability close to 0.5, when the thermal noise is equal to or greater than the digital signal. In a simple hypothetical realization of a thermal noise driven gate, the lower limit of energy needed to generate the digital signal is 1.1*kT/bit. The arrangement has potentially improved energy efficiency and it is free of leakage current, crosstalk and ground plane electromagnetic interference problems. Disadvantage is the large number of redundancy elements needed for low-error operation.

description: We investigate the algebraic structure of the Feynman propagator with a general time-dependent quadratic Hamiltonian system. Using the Lie-algebraic technique we obtain a normal-ordered form of the time-evolution operator, and then the propagator is easily derived by a simple ``Integration Within Ordered Product" (IWOP) technique.It is found that this propagator contains a classical generating function which demonstrates a new correspondence between classical and quantum mechanics.
