Asteroseismology of Kepler Algol-type oscillating eclipsing binaries

Context. This research paper contains light curve modelling, spectroscopy, and detailed asteroseismic studies for four out of a total of five semi-detached eclipsing binaries with a δ Scuti component that have been detected to date through Kepler mission; these objects are KIC 06669809, KIC 10581918, KIC 10619109, and KIC 11175495. Aims. The goal is to study the pulsational characteristics of the oscillating stars of the systems and to estimate their absolute parameters and enrich the, thus far, poor sample of such systems. Methods. Ground-based spectroscopic observations provided the means to estimate the spectral types of the primary components and to model the light curves with higher certainty. The photometric data were analysed using eclipsing binary modelling techniques, while Fourier analysis was applied on their residuals to reveal the pulsation frequency modes. Results. The results of analyses show that the primaries are pulsating stars of δ Scuti type and that all systems belong to the group of Algol-type binaries that have an oscillating star (oEA stars). The primaries of KIC 06669809, KIC 10581918, and KIC 10619109 pulsate in three, two, and five frequencies, respectively, and more than 200 others are detected as combination frequencies. The pulsator of KIC 11175495 is the youngest and fastest δ Scuti star that has ever been found in a binary system and oscillates in three main non-radial frequencies and in another 153 dependent frequencies. Moreover, comparisons of the properties of these binaries with other systems of the same type and with theoretical models of pulsating stars are also presented and discussed.
How to establish and maintain outsourcing relationships between Logistics Service Providers and their clients ? 101 – Complexity in Business : Insights and solutions

Purpose: What influences collaboration between LSPs and their clients in the midst of uncertainty lies in the analysis of supply chain collaboration between logistics service providers (LSPs) and their clients, with a main focus set on communication, coordination, and technological issues, (i.e. rational measures to achieve defined goals), resulting interdependencies and complexity as well as organizational coordination principles and mechanisms. Qualitative interviews with experts from leading LSPs on how they establish and maintain outsourcing relationships operationally were conducted and analyzed by open, axial and selective coding, following a grounded theory approach methodology. Coordination as a precondition for collaboration is based on communication between LSPs and their clients. The more complex and/or interdependent processes reveal themselves to be in an outsourcing relationship, the more intense coordination efforts have to be established and maintained for outsourcing operations to reduce uncertainty. Furthermore, collaboration level between LSPs and clients is influenced by several factors, such as strategic importance of the client, general contract size and transaction frequency, a common understanding of the mutual dependency arising from collaboration, trust, the depth of the comfort level in interpersonal relations and, finally, the degree of standardization of communication on the operational level. Moreover, it indicates that operational coordination efforts seem to be limited to standardization of input, output and work processes. Otherwise, coordination costs would rise considerably. This leads to the conclusion that the interdependency of outsourced processes is to be reduced, which goes hand-in-hand with lower and controllable uncertainty and subsequently lower risks.
Hot phonon decay in supported and suspended exfoliated graphene

Near infrared pump-probe spectroscopy has been used to measure the ultrafast dynamics of photoexcited charge carriers in monolayer and multilayer graphene. We observe two decay processes occurring on 100-fs and 2-ps time scales. The first is attributed to the rapid electron-phonon thermalization in the system. The second time scale is found to be due to the slow decay of hot phonons. Using a simple theoretical model we calculate the hot phonon decay rate and show that it is significantly faster in monolayer flakes than in multilayer ones. We observe this enhanced decay rate in both supported and suspended flakes and thereby demonstrate that it has an intrinsic origin. Possible decay mechanisms, such as flexural phonons, that could cause such an enhancement are discussed.
Local Ensemble Transform Kalman Filter for Earth-System Models: An application to Extreme Events

Earth-system models describe the interacting components of the climate system and technological systems that affect society, such as communication infrastructures. Data assimilation addresses the challenge of state specification by incorporating system observations into the model estimates. In this research, a particular data assimilation technique called the Local Ensemble Transform Kalman Filter (LETKF) is applied to the ionosphere, which is a domain of practical interest due to its effects on infrastructures that depend on satellite communication and remote sensing. This dissertation consists of three main studies that propose strategies to improve spaceweather specification during ionospheric extreme events, but are generally applicable to Earth-system models: Topic I applies the LETKF to estimate ion density with an idealized model of the ionosphere, given noisy synthetic observations of varying sparsity. Results show that the LETKF yields accurate estimates of the ion density field and unobserved components of neutral winds even when the observation density is spatially sparse (2% of grid points) and there is large levels (40%) of Gaussian observation noise. Topic II proposes a targeted observing strategy for data assimilation, which uses the influence matrix diagnostic to target errors in chosen state variables. This strategy is applied in observing system experiments, in which synthetic electron density observations are assimilated with the LETKF into the Thermosphere-IonosphereElectrodynamics Global Circulation Model (TIEGCM) during a geomagnetic storm. Results show that assimilating targeted electron density observations yields on average about 60%–80% reduction in electron density error within a 600 km radius of the observed location, compared to 15% reduction obtained with randomly placed vertical profiles. Topic III proposes a methodology to account for systematic model bias arising
City 2 City

In this work we explore methods of style transfer between images of different cities. Given a picture taken in one city, we want to generate an image in the style of another city while retaining the semantics of the original image. Without having access to paired data for this problem, we try different approaches to accomplish this task. We investigate using unpaired image-to-image translation models. We also leverage depth data corresponding to images at training time to do imageto-image translation at test time. We assembled image (and depth) datasets from cities such as Paris, Manhattan, and Venice for training each model.
Stored Electromagnetic Energy and Antenna

Decomposition of the electromagnetic energy into its stored and radiated parts is instrumental in the evaluation of antenna Q and the corresponding fundamental limitations on antennas. This decomposition is not unique and there are several proposals in the literature. Here, it is shown that stored energy de ned from the di erence between the energy density and the far eld energy equals the new energy expressions proposed by Vandenbosch for many cases. This also explains the observed cases with negative stored energy and suggests a possible remedy to them. The results are compared with the classical explicit expressions for spherical regions where the results only di er by ka that is interpreted as the fareld energy in the interior of the sphere. Numerical results of the Q-factors for dipole, loop, and inverted L-antennas are also compared with estimates from circuit models and di erentiation of the impedance. The results indicate that the stored energy in the eld agrees with the stored energy in the Brune synthesized circuit models whereas the di erentiated impedance gives a lower value for some cases. The corresponding results for the bandwidth suggest that the inverse proportionality between bandwidth and Q depends on the relative bandwidth or equivalent the threshold of the re ection coe cient. The Q from the di erentiated impedance and stored energy are most useful for relative narrow and wide bandwidths, respectively.
Design and standalone characterisation of a capacitively coupled HV-CMOS sensor chip for the CLIC vertex detector

The concept of capacitive coupling between sensors and readout chips is under study for the vertex detector at the proposed high-energy CLIC electron positron collider. The CLICpix Capacitively Coupled Pixel Detector (C3PD) is an active High-Voltage CMOS sensor, designed to be capacitively coupled to the CLICpix2 readout chip. The chip is implemented in a commercial 180 nm HV-CMOS process and contains a matrix of 128×128 square pixels with 25μm pitch. First prototypes have been produced with a standard resistivity of ∼20 Ωcm for the substrate and tested in standalone mode. The results show a rise time of ∼20 ns, charge gain of 190 mV/ke− and ∼40 e− RMS noise for a power consumption of 4. 8μW/pixel. The main design aspects, as well as standalone measurement results, are presented.
Choice Overload, Satisficing Behavior, and Price Distribution in a Time Allocation Model

Recent psychological research indicates that consumers that search exhaustively for the best option of a market product—known as maximizers—eventually feel worse than consumers who just look for something good enough—called satisficers. We formulate a time allocation model to explore the relationship between different distributions of prices of the product and the satisficing behavior and the related welfare of the consumer. We show numerically that, as the number of options becomes large, the maximizing behavior produces less and less welfare and eventually leads to choice paralysis—these are effects of choice overload—whereas satisficing conducts entail higher levels of satisfaction and do not end up in paralysis. For different price distributions, we provide consistent evidence that maximizers are better off for a low number of options, whereas satisficers are better off for a sufficiently large number of options. We also show how the optimal satisficing behavior is affected when the underlying price distribution varies. We provide evidence that the mean and the dispersion of a symmetric distribution of prices—but not the shape of the distribution—condition the satisficing behavior of consumers. We also show that this need not be the case for asymmetric distributions.
SEGMENTASI MODEL AKTIF KONTUR SBGFRLS PADA PAMOR KERIS

Pamor merupakan hiasan atau motif atau ornamen yang terdapat pada bilah tosan aji (Keris, Tombak, Pedang atau Wedung dan lain lainnya). Penulis tertarik untuk melakukan penelitian segmentasi pada pamor keris dengan metode Selective Binary dan Gaussian Filtering Regularized Set Level (SBGFRLS). Metode region based active contour model (ACM) digunakan dalam tulisan ini. Hal ini dilaksanakan dengan pengolahan khusus metode Selective Binary dan Gaussian Filtering Regularized Set Level (SBGFRLS), yang langkah pertamanya secara selektif menentukan fungsi level set menjadi biner, dan kemudian menggunakan kernel Gaussian smoothing untuk mengaturnya. Keuntungan dari metode ini adalah sebagai berikut. Pertama, sebuah wilayah fungsi signed pressure force (SPF) secara efisien dapat menghentikan kontur di tepi yang lemah atau tepi yang kabur. Kedua, eksterior dan interior batas dapat secara otomatis terdeteksi dengan kontur awal berada di mana saja pada citra. Ketiga, ACM dengan SBGFRLS memiliki sifat segmentasi lokal atau global selektif. Hal ini dapat mensegmen tidak hanya obyek yang diinginkan tetapi juga obyek obyek lainnya. Keempat, fungsi level set dapat dengan mudah diinisialisasi dengan fungsi biner, yang tentunya lebih efisien untuk dibangun daripada signed distance function (SDF). Biaya komputasi untuk re-inisialisasi juga dapat dikurangi.
YIELD AND QUALITY OF ACCESSIONS ACCORDING TO REGROWTH AGES AND CLIMATIC SEASONS

In silvopastoral systems, high nutritional quality shrub legumes represent an alternative to shortage of grasses in dry periods of the year. The effect of different regrowth ages (6, 9, 12 and 15 weeks) in three climatic seasons (rainy, winter and dry seasons, 2007-2008) of four Cratylia argentea accessions (18516, 18666, 18668 and 18676) were evaluated in Veracruz, Mexico, for dry matter yield (DMY), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin (Lig), crude protein (CP) and in situ DM degradation (ISDMD). Dry matter yield (mean ± standard error) was affected by season and regrowth age, but not by accession or interactions. The dry season showed the largest DMY (3632 ± 306 kg·ha-1), representing 45 % of total forage yield, followed by the rainy (33 %, 2615±188 kg·ha-1) and winter (22 %; 1733 ± 61 kg·ha-1) seasons. For NDF, ADF, Lig and CP, statistical effects were found for regrowth age in all three seasons. The largest ISDMD occurred in the rainy and dry seasons, reaching average values of 66 and 65 % at 72 h of incubation, respectively. The dry season was the best period for DMY and ISDMD, making Cratylia argentea a reliable feed resource for silvopastoral systems.

In vitro Fermentation Characteristics and Rumen Microbial Population of Diet Supplemented with Saccharomyces cerevisiae and Rumen Microbe Probiotics

The objective of this study was to select three strains of probiotic Saccharomyces cerevisiae and to evaluate the effect of S. cerevisiae and rumen bacteria isolate (MR4) supplementation and their combination on rumen fermentability and rumen microbial population. Experiment 1 was designed in a 4 x 5 factorial randomized block design with 3 replications. The first factor was S. cerevisiae strain consisted of control treatment (without S. cerevisiae supplementation), NBRC 10217, NRRL Y 567 and NRRL 12618, and the second factor was incubation time consisted of 0, 1, 2, 3, and 4 h. Ration was basal ration for feedlot with forage to concentrate ratio (F:C)= 60:40. Dosage of each treatment with S. cerevisiae was 5 x 1010 cfu/kg ration. Experiment 2 was designed in randomized block design with 4 treatments: P0= basal ration of feedlot; P1= P0 + S. cerevisiae; P2= P0 + MR4 isolate (5 x 107 cfu/kg ration); P3= P0 + S. cerevisiae and MR4 isolate. The result of experiment 1 showed that supplementation of S. cerevisiae NRRL 12618 had the highest S. cerevisiae population and increased rumen bacterial population. This strain was selected as probiotic in experiment 2. The result from experiment 2 showed that probiotic supplementation stabilized rumen pH and produced the highest NH3 concentration (P<0.05) and bacterial population (P<0.05). As compared with control, all treatments reduced protozoa population (P<0.05). Combination of S. cerevisiae and MR4 probiotics produced the highest total volatile fatty acids (VFA) and isovalerate (P<0.05). It was concluded that strain S. cerevisiae NRRL 12618 had potential as probiotic yeast. Supplementation with this strain increased fermentability, rumen isoacid and decreased A:P ratio. Those abilities could be improved with MR4 rumen isolate probiotic.
M ASTER RESEARCH I NTERNSHIP

Scheduling for real-time interactive multimedia systems (IMS) raises speciﬁc challenges that require particular attention. Examples are triggering and coordination of heterogeneous tasks, especially for IMS that use a physical time, but also a musical time that depends on a particular performance, and how tasks that deal with audio processing interact with control tasks. More-over, IMS have to ensure a timed scenario, for instance speciﬁed in an augmented musical score, and current IMS do not deal with their reliability and predictability. We present how to formally interleave audio processing with control by using buffer types that represent audio buffers and the way of interrupting computations that occur on them, and how to check the property of time-safety of IMS timed scenarios, in particular augmented scores for the IMS Antescofo for automatic accompaniment developed at Ircam. Our approach is based on the extension of an intermediate representation similar to the E code of the real-time embedded programming language Giotto, and on static analysis procedures run on the graph of the intermediate representation.
Single-crystal absorption and reflection infrared spectroscopy of birefringent grossular-andradite garnets

Reduction in symmetry of optically anomalous garnets from laid to 1T or Fddd by cation ordering, as indicated by crystallography, implies that a large number of vibrations (129 or 98) should be infrared (IR) active. Yet, only the pattern characteristic ofisotropic isometric garnets was observed in single-crystal polarized and unpolarized IR reflectance spectra from 80 to 4000 cm-' of four birefringent garnets (GrroAnuAlo, GrnrAn,, AnnoGrrSp,, and GruorAn.urSp, rAl,Pyor). These samples are nearly identical to those whose structures have been crystallographically refined. We also present the first single-crystal IR absorption spectrum that resolves the entire fundamental region and find this compares closely with data from reflection measurements. An extra band seen near 690 cm-t is attributed to an overtone because it is present in isotropic garnets. The absence oforientational dependence and existence of 17 (or fewer) IR fundamentals (rather than the 98-129 expected) is consistent with an IaSd space group: ordering of divalent or trivalent cations is not apparent. The contrasting results from spectroscopy and crystallography may indicate that strain causes anomalous optical anisotropy in garnet (as occurs in diamond and quartz) in that X-ray diffraction requiresjuxtaposition of 1000 unit cells, whereas lattice vibrations can be produced by isolated molecules.
Reformasi: Crisis and Change in Indonesia

Political rapes, like other rapes, are notoriously difficult as a subject of reporting and critical analysis for observers, not to speak of their experience for victims. This is especially true when the subject is unfamiliar territory for the analysts, as the case of May 1998 has been to many] ava-based or J akartabiased Indonesians, myself included. These are all obvious points. One bitter implication I wish to consider here is that the state apparatuses are not able, even if they were willing, to satisf)1 the public demand to investigate the May 1998 case thoroughly, and hold the culprits responsible, in ways that follow the official procedures and meet the conventional standards of justice and truth. The May 1998 rapes opened a new chapter in the history of Indonesia's political violence. Although not the first incident of its kind in the centre of the state political space, it appeared to have no resonance in the memory of a large portion of the population, including those actively involved in the case. l
CO2 and Water Activation on Ceria Nanocluster Modified TiO2 rutile (110)

Surface modification of TiO2 with metal oxide nanoclusters is a strategy for the development of new photocatalyst materials. We have studied modification of the (110) surface of rutile TiO2 with ceria nanoclusters using density functional theory corrected for on-site Coulomb interactions (DFT+U). We focus on the impact of surface modification on key properties governing the performance of photocatalysts, including light absorption, photoexcited charge carrier separation, reducibility and surface reactivity. Our results show that adsorption of the CeO2 nanoclusters, with compositions Ce5O10 and Ce6O12, is favourable at the rutile (110) surface and that the nanocluster-surface composites favour non-stoichiometry in the adsorbed ceria so that reduced Ce ions will be present in the ground state. The presence of reduced Ce ions and low coordinated O sites in the nanocluster lead to the emergence of energy states in the energy gap of the TiO2 host, which potentially enhance the visible light response. We show, through an examination of oxygen vacancy formation, that the composite systems are reducible with moderate energy costs. Photoexcited electrons and holes localize on Ce and O sites of the supported nanoclusters. The interaction of CO2 and H2O is favourable at multiple sites of the reduced CeOx- TiO2 composite surfaces. CO2 adsorbs and activates, while H2O spontaneously dissociates at oxygen vacancy sites.
Böhlke , 1965 ( Teleostei : Characiformes ) , a phreatobic fish from eastern Brazil : Comments on Sampaio et al . ( 2012 )

Stygichthys typhlops Brittan & Böhlke, 1965 is the only known troglobiotic characiform fish in South America, now only accessible through artificial wells and 'cacimbas' in the Jaiba karst area, State of Minas Gerais, eastern Brazil. The species was described based on a single specimen collected during a well drilling operation (Brittan and Böhlke 1965). Additional specimens were not collected again until 2004, almost 40 years after its description (Moreira et al. 2010). Stygichthys typhlops faces a high risk of extinction due to the lowering of the water table caused by groundwater withdrawal for extensive irrigation in the region. This threat promoted the species to be included in the Brazilian Red List of Threatened Species (Ministério do Meio Ambiente 2008). After its rediscovery, information on several aspects of the biology of S. typhlops has been published, such as physiology of pigmentation (Felice et al. 2008), chronobiology (Trajano et al. 2011), behavior (Parzefall and Trajano 2010), conservation (Bichuette and Trajano 2010), habitat and distribution (Trajano and Bichuette 2010).
TITLE A Methodological Contribution to Identifying Depressed College Students

ABSTRACT Research directed toward examining clinical depression aiming college students requires valid criterion ieasures for identifying depressed individua4s. The Beck Depression Inventory (BDI), the most widely-used self-report screening instrument for identifying depressed college students, has been criticized for its heavy emphasis on . cognitive items resulting in a high false positive rate for classifying depressives. The Depressive Symptoms Questionnaire (DSQ), a self-report instrument loaded with,somatic and behavioral components, was constructed. Undergraduates (Nr673) completed both the BDI and thb DSQ. To evaluate the classification validity of the cutting scores of the BDI, the DSQ, and the two instruments combined, 48 diagnostic interviews were conducted by clinical psychology graduate students. Results showed that the hit rate for true positives of the BDI/DSQ-screened group was significantly greater than the hit rate for the BDI-screened group. The combination of the BDI and DSQ improved the identification of diagnosable depressed college students and identified significantly more individuals with major depressive episodes. (Author/NRB)
