Graph Estimation for Matrix-variate Gaussian Data

Matrix-variate Gaussian graphical models (GGM) have been widely used for modeling matrix-variate data. Since the support of sparse precision matrix represents the conditional independence graph among matrix entries, conducting support recovery yields valuable information. A commonly used approach is the penalized log-likelihood method. However, due to the complicated structure of precision matrices in the form of Kronecker product, the log-likelihood is non-convex, which presents challenges for both computation and theoretical analysis. In this paper, we propose an alternative approach by formulating the support recovery problem into a multiple testing problem. A new test statistic is developed and based on that, we use the popular Benjamini and Hochberg's procedure to control false discovery rate (FDR) asymptotically. Our method involves only convex optimization, making it computationally attractive. Theoretically, our method allows very weak conditions, i.e., even when the sample size is finite and the dimensions go to infinity, the asymptotic normality of the test statistics and FDR control can still be guaranteed. We further provide the power analysis result. The finite sample performance of the proposed method is illustrated by both simulated and real data analysis.
In situ measurements of acoustic impedance for car applications: influence of forming effect

This paper deals with measurements of acoustic impedance of porous materials used in automotive industry. Recent sensors, combining particle velocity and pressure measurements, are used in this application. These sensors offer the possibility to easily assess the acoustic impedance of the material. The study is divided in three steps. A first test is carried out in a Kundt’s tube, in order to compare impedance measurements obtained with the new sensor with the transfer function method, using two microphones. The following step consists in measuring acoustic impedance in a semi-anechoic room, to determine the influence of the source’s position, as well as the effect of confined environment. In the last step, effects of different assembling an automotive foam absorber (forming, edge constraints) on acoustic impedance are studied. Euronoise 2006, Tampere, Finland C. Sandier, C. Peteul, E.

Geothermal Modeling of Kızılcahamam-Çamlıdere Area Using 3 D Imaging Technique

Geothermal energy has long been used for various purposes. Geothermal energy was used for bath and health care since ancient times. With the increase in the population, it is being used today for industrial and energy production. This paper examines the geothermal structure of Northern Ankara-NAF (Northern Anatolian Fault Zone) regions to reveal its tectonic features, and the relationships of the region with earthquakes. The 3D geological features of the area are investigated using the resistivity data and tectonic and the quake values. The resistivity data obtained by MTA (Mineral Research and Exploration of Turkey) are reached by geothermal measurements in the area in 1999. In Kızılcahamam town of Ankara Province, geothermal exploration was performed using geoelectrical methods. During the study, electrode measurement scheme was planned according to the Schlumberger expansion. AB/2 spacing is between 1900 m. and 2000 m. Data obtained from geoelectrical methods were processed to delineate the subsurface structure. Also, lithological components were determined and the previously known fault structure was shown. Since the 3D works have been more feasible recently, the received results are transferred into the 3D imaging platform taking advantage of 2D electrical resistivity maps. The low resistivity values obtained in 3D imaging are gathered that the temperature values of the area are high. On the other hand, as the pull-apart between NAF and Kırıkkale fault trending NE-SW of the region is in form of basin, the study area is observed to own opening tectonics. Thus, when the seismic activity is considered, it reveals important findings about the presence of geothermal fields in the local.
Rape-Related Beliefs and Social Reactions

Many agree that sexual violence is a pervasive problem, but there is less disagreement regarding how to define or label it. Recent research has determined that rape-related beliefs are the strongest predictors for how both victims and non-victims conceptualize and label unwanted sexual experiences. What is less understood is the way that this conceptualization influences how non-victims respond to a disclosure. The current study sought to fill this gap by examining how rape-related beliefs affect the definitional and labeling process and how this process affects responses to a disclosure of sexual violence in a sample of non-victims. Participants included 119 female college students (Mage = 19.23, SD = 1.98; 81% White). Results revealed that endorsing distorted rape-related attitudes was a significant predictor for how one labeled one of the vignettes (i.e. “seduction rape” vignette), such that having more distorted rape-related attitudes led to labeling the experience as something other than rape (i.e. a miscommunication or a mistake). Results also revealed that this conceptualization subsequently affected responses for one of the vignettes (i.e. “seduction rape” vignette), such that those who labeled it as something other than rape were more likely to respond more negatively and less positively to the victim. These results suggest that endorsing rape-related beliefs can affect the conceptualization of an experience and that this conceptualization can affect responses to a disclosure. Implications and future directions are discussed. RAPE-RELATED BELIEFS AND SOCIAL REACTIONS 3
Petrology, Geochemistry and Geochronology of Kaua‘i Lavas over 4·5 Myr: Implications for the Origin of Rejuvenated Volcanism and the Evolution of the Hawaiian Plume

Kaua‘i lavas provide a unique opportunity to examine over 4·5 Myr of magmatic history at one location along the Hawaiian chain. New field, geochronological, petrological and geochemical results for a large suite of shield, post-shield and rejuvenated lavas are used to examine models for the origin of rejuvenated volcanism, and to evaluate the composition and structure of the Hawaiian plume. Kaua‘i has the most voluminous ( 58 km based on new field and water well interpretations) and longest-lived suite of rejuvenated lavas ( 2·5 Myr) in Hawai‘i. New K^Ar ages and field work reveal an 1 Myr gap (3·6^2·6 Ma) in volcanism between post-shield and rejuvenated volcanism. Isotopic and trace element ratios, and modeling of major elements of Kaua‘i’s rejuvenated lavas require low-degree melting (0·02^2·6%) at 1525 108C and 3·5^4·0 GPa of a heterogeneous, peridotitic plume source. High-precision Pb, Sr, Nd and Hf isotopic, and inductively coupled plasma mass spectrometry trace element data show substantial source variations with a dramatic increase in the depleted component in younger lavas. Some shield, post-shield and rejuvenated lavas (4·3^0·7 Ma) have high Pb*/Pb* (radiogenic Pb produced since the formation of the Earth) values (40·947) indicative of Loa-type compositions, the first reported Loa values in rocks 43 Ma, questioning previous models for the emergence of the Loa component in Hawaiian lavas.The timing, long duration, temporal variation in rock types and voluminous pulse of rejuvenated volcanism (58 km), and the synchronous eruption of compositionally similar rejuvenated lavas, indicating tapping of common components along 350 km of the Hawaiian chain, are inconsistent with current models for this volcanism. Combining the lithospheric flexure and secondary zone of melting models provides a physical mechanism to initiate and focus the melting at shallower levels within the plume (flexural uplift) with a means to extend the duration of Ko loa volcanism at higher degrees of partial melting.

Metacognitive reading strategies in learning disability: Relations between usage level, academic self-efficacy and self-concept

The purpose of this study is to investigate the relationship between the usage levels of metacognitive reading strategies by students diagnosed with specific learning disability (SLD), academic self-efficacy and the concept of self, in comparison to their typically developing (TD) peers. The data to be used in the study were collected using the Metacognitive Awareness of Reading Strategies Inventory, the Academic Self-efficacy Scale, the Piers-Harris Children’s Self-concept Scale and the Demographics Information Form. The study was conducted among a total of 119 students in the fifth, sixth, seventh and eighth grades in Izmir Province, including 59 students diagnosed with SLD and 60 TD students. Considering the results of the study, in comparison to TD students, students diagnosed with SLD were significantly inadequate in terms of the usage levels of metacognitive reading strategies, levels of academic self-efficacy, and the intelligence/school subdimensions of the concept of self.
Surface Morphology , Optical Conductivity , Localized States and Dielectric Constants of Sprayed Nickel Oxide Films at Different Substrate Temperatures

Thin films of nickel oxide (NiO) were deposited on glass substrates at a different temperature of growth using a spray pyrolysis technique. X-ray diffraction (XRD) and optical properties have been studied for the properties of the samples obtained. Analysis of XRD data show that at a low growth temperature, an amorphous form has been obtained, while at high growth temperature (Tsub ≥ 275 C), single phase of the NiO formed which has a cubic structure. Optical properties were examined using spectral measurement at wavelength range of 300-2500nm. Optical constants (n and k) were calculated from corrected transmittance and corrected reflectance. The data obtained show that the direct transition (Eg) decreased from 3.738 to 3.146 eV and the indirect transition change from 2.790 to 2.049eV with increasing temperature. On the contrary, Urbach energy (band tail width), EU was found to be decreased from 0.65 to 0.36 eV. This behavior is believed to be associated with the increase of substrate temperatures. Optical conductivity, dielectric constants, optical density, skin depth, and electrical susceptibility were discussed as functions of substrate temperatures. From these results, NiO films has been categorized as an excellent material for optoelectronic applications and a potential candidate for solar cell applications because of its tune-ability for optimization.
Axisymmetric particle-driven gravity currents

Axisymmetric gravity currents that result when a dense suspension intrudes under a lighter ambient fluid are studied theoretically and experimentally. The dynamics of and deposition from currents flowing over a rigid horizontal surface are determined for the release of either a fixed volume or a constant flux of a suspension. The dynamics of the current are assumed to be dominated by inertial and buoyancy forces, while viscous forces are assumed to be negligible. The fluid motion is modelled by the single-layer axisymmetric shallow-water equations, which neglect the effects of the overlying fluid. An advective transport equation models the distribution of particles in the current, and this distribution determines the local buoyancy force in the shallow-water equations. The transport equation is derived on the assumption that the particles are vertically well-mixed by the turbulence in the current, are advected by the mean flow and settle out through a viscous sublayer at the bottom of the current. No adjustable parameters are needed to specify the theoretical model. The coupled equations of the model are solved numerically, and it is predicted that after an early stage both constant-volume and constant-flux, particle-driven gravity currents develop an internal bore which separates a supercritical particle-free region upstream from a subcritical particle-rich region downstream near the head of the current. For the fixed-volume release, an earlier bore is also predicted to occur very shortly after the initial collapse of the current. This bore transports suspended particles away from the origin, which results in a maximum in the predicted deposition away from the centre. To test the model several laboratory experiments were performed to determine both the radius of an axisymmetric particle-driven gravity current as a function of time and its deposition pattern for a variety of initial particle concentrations, particle sizes, volumes and flow rates. For the release of a fixed volume and of a constant flux of suspension, the comparisons between the experimental results and the theoretical predictions are fairly good. However, for the current of fixed volume, we did not observe the bore predicted to occur shortly after the collapse of the current or the resulting maximum in deposition downstream of the origin. This is unlike the previous study of Bonnecaze et al. (1993) on two-dimensional currents, in which a strong bore was observed during the slumping phase. The radial extent R of the deposit from a fixed-volume current is accurately predicted by the model, and for currents whose particles settle sufficiently slowly, we find that R = 1.9(g′0 V3 / v2s)1/8, where V is the volume of the current, vs is the settling velocity of a particle in the suspension and g’0 is the initial reduced gravity of the suspension.
Protective Effect Against Hydroxyl Radical-induced DNA Damage and Antioxidant Mechanism of [6]-gingerol: A Chemical Study

radical (IC50 228.40 ± 9.20 μM), DPPH• radical (IC50 27.35 ± 1.44 μM), and ABTS • radical (IC50 2.53 ± 0.070 μM), and reduce Cu ion (IC50 11.97 ± 0.68 μM). In order to investigate the possible mechanism, the reaction product of [6]-gingerol and DPPH• radical was further measured using HPLC combined mass spectrometry. The product showed a molecular ion peak at m/z 316 [M+Na], and diagnostic fragment loss (m/z 28) for quinone. On this basis, it can be concluded that: (i) [6]-gingerol can effectively protect against •OH-induced DNA damage; (ii) a possible mechanism for [6]-gingerol to protect against oxidative damage is •OH radical scavenging; (iii) [6]-gingerol scavenges •OH radical through hydrogen atom (H•) transfer (HAT) and sequential electron (e) proton transfer (SEPT) mechanisms; and (iv) both mechanisms make [6]-gingerol be oxidized to semi-quinone or quinone forms.

Experimental Streptococcus iniae Infection in Japanese Flounder Paralichthys olivaceus

The capability of Streptococcus iniae to cause disease in Japanese flounder was investigated by oral and bath (30 min) challenges with low, medium and high inoculation doses. Only with the highest inoculation dose, 9.9t107 CFU/100 g body weight, the oral challenge induced deaths. In the bath challenge deaths were induced even at the lowest inoculation dose, 2.9t103 CFU/mL water. Hemorrhagic lesions on the fins were observed in dead fish challenged by both methods. It is suspected that S. iniae entered through the body surface such as abrasive sites of the fins to cause disease.

In this research the authors examine whether counterfactual thinking, the process of imagining alternatives to reality, can have a detrimental impact on consumers' feelings. Five studies examine the dysfunctional role of counterfactual thinking in the presence of Minimum Purchase Requirement conditional message framing ("X % off all purchases if you spend at least $Y"), and its affective consequences. Results show that the presence or absence of the minimum amount restriction (Studies 1A and 1B), success or failure to meet the restriction (Studies 2A and 2B), and perceived closeness (i.e., outcome proximity) to success or failure in meeting the restriction (Study 3), drastically influence consumer affect to the extent that participants receiving an inferior deal exhibited higher satisfaction than those receiving a superior deal. It is suggested that such promotion-induced counterfactual thinking polarizes consumer satisfaction, which may impede consumers from arriving at optimal conclusions.
Development of a remote photoplethysmographic technique for human biometrics

Non-contact reflection photoplethysmography (NRPPG) is being developed to trace pulse features for comparison with contact photoplethysmography (CPPG). Simultaneous recordings of CPPG and NRPPG signals from 22 healthy subjects were studied. The power spectrum of PPG signals were analysed and compared between NRPPG and CPPG. The recurrence plot (RP) was used as a graphical tool to visualize the time dependent behaviour of the dynamics of the pulse signals. The agreement between NRPPG and CPPG for physiological monitoring, i.e. HRV parameters, was determined by means of the Bland-Altman plot and Pearson's correlation coefficient. The results indicated that NRPPG could be used for the assessment of cardio-physiological signals.
Government Responses to Terrorism: Critical Views of Their Impacts on People and Public Administration

Following the tragic, massive terrorist attacks on the United States in September 2001, many antiterrorist laws, policies, and institutions have emerged to wage war on terrorism. These antiterrorist initiatives have major consequences for individuals, societies, and nations all over the world. Although controversies have proliferated with regard to the implications of counterterrorism for people’s basic rights, the debate remains fragmented and often unfocused. This article examines the critical impact of new antiterrorist initiatives on the fundamental rights and responsibilities of citizens and others, with special reference to public administration. Citizenship has been a central concern in both practical and academic public administration in most constitutionally democratic societies, emphasizing people’s rights and responsibilities in relation to the state and to society in general. It is argued that citizenship represents the fundamental basis of constitutional democracy in terms of the reciprocal relationships between the state and people; thus, it provides the framework within which public adminis
Ultra-light dark matter in ultra-faint dwarf galaxies

Cold Dark Matter (CDM) models struggle to match the observations at galactic scales. The tension can be reduced either by dramatic baryonic feedback effects or by modifying the particle physics of CDM. Here, we consider an ultra-light scalar field DM particle manifesting a wave nature below a DM particle mass-dependent Jeans scale. For DM mass m ∼ 10−22 eV, this scenario delays galaxy formation and avoids cusps in the centre of the dark matter haloes. We use new measurements of half-light mass in ultra-faint dwarf galaxies Draco II and Triangulum II to estimate the mass of the DM particle in this model. We find that if the stellar populations are within the core of the density profile then the data are in agreement with a Wave Dark Matter model having a DM particle with m ∼ 3.7–5.6 × 10−22 eV. The presence of this extremely light particle will contribute to the formation of a central solitonic core replacing the cusp of a Navarro–Frenk–White profile and bringing predictions closer to observations of cored central density in dwarf galaxies.
Anatomical study of the Iranian brown bear’s skull (Ursus arctos): A case report

The Brown bear (Ursusarctos) is a species at risk of extinction. It is considered the largestcarnivore and lives in northern Iran. Several studies on the structure of skullhave been accomplished in differentanimals. The aim of this study was the inscription of gross anatomicalcharacteristics of skulls of three Iranian adult male brown bears that weretransferred to the Anatomical Departmentof the Faculty of Veterinary Medicine of Semnan University. After processing,that included cleaning, degreasing and bleaching, skulls were studied from thedorsal or frontal, ventral, lateral, rostral, caudal and medial views. Thefacial part of the brown bear’s skull from dorsal view was small and thecranium was seen quadrilateral and larger than the dogs. The facial part oflacrimal bone and also the optic groove of presphenoid were absent. There wasnot articulation between maxillary and nasal bones. The interincisive canal waspresent and situated inter palatine processes of incisive bones. The orbitalcavity was small in brown bear. Lacrimal canal was formed by lacrimal andmaxillary bones. The interparietal bone and external sagittal crest in brownbear were seen as being shorter than the dogs. Tympanic bulla was very smalland jugular foramen rounded. The external acoustic meatus was formed bysquamous and tympanic part of temporal bone. In conclusion, the brown bear’sskull has different important macroscopic characteristics compared to othercarnivores
