Fourth-Order Butterworth Active Bandpass Filter Design for Single-Sided Magnetic Particle Imaging Scanner

This paper describes the design and simulation of a fourth-order Butterworth active bandpass filter designed for single-sided magnetic particle imaging (MPI) scanner. Bandpass filters (BPF) are used in MPI scanner set-up to attenuate the harmonic distortions generated by the power amplifier before passing the purely sinusoidal signal to the excitation (Drive) coils. The BPF is designed based on the excitation frequency of 22.8 kHz, having Butterworth response, and realized using Sallen-Key topology by cascading one second-order highpass filter and one second-order lowpass filter, with values of the passive components calculated using the coefficient matching method. MATLAB and NI Multisim software are used to simulate the filter, and the results are compared. The magnitude response obtained using MATLAB have monotonic amplitude response in the pass and stopband, and maximally flat with small ripples in the passband than the NI Multisim implementation, while NI Multisimimplementation has better roll-off than MATLAB implementation.
Frog morphometrics : a cautionary tale

Scant attention has been paid to measurement error in frog morphometric studies. We study both interobserver effects of measurement on the same specimens of Vanzolinius discodactylus (Anura, Leptodactylidae) and intraobserver effect of repeated measurements on a single V. discodactylus specimen. Interobserver measurements differ statistically and result in different biological interpretations in some cases. Evidence is provided that log transformation of raw data is often unnecessary. Allometric transformation of measurement variables to remove size effect requires parallel regression slopes of variable against size. This requirement is not met with the V. discodactylus data, nor is it likely to be met when several variables are used in a morphometric study. We recommend: assume measurement differences between sexes in frogs and analyze data separately by sex; consider and select the most appropriate statistical model options for data analyses; avoid pseudoprecise measurements; do not rush to logarithmic transformation; remeasure at least one individual frog 20 times to provide an assessment of measurement error in data interpretation; be conservative in drawing biological inferences from morphometric analyses, basing interpretations and conclusions only on very robust effect size estimates and differences.

Cenozoic strike-slip faults in the northern Wassuk Range, Walker Lane

The N. Wassuk Ra. yields estimates of right-lateral Cenozoic strain in a portion of the northwest-trending Walker Lane, which has a total estimated right-lateral strain of 48--60 km (Ekren et al., 1984). The net right-lateral strain is < 10 km within an east-west 50 km-long segment extending from the N. Wassuk Ra. west to the Pine Nut Mts on the basis of continuous Jurassic plutonic units: Yerington batholith and quartz monzodiorite porphyry dikes. One of two dikes in the N. Wassuk Ra. may correlate easterly to Gillis Ra. , suggesting [approximately]10 or 25 km right-lateral offset (Diles and R. Hardyman, unpub). In the N. Wassuk Ra. there are several ages of northwesterly striking faults. The oldest are [approximately]N45[degree]W striking, steeply dipping faults including the White Mt. and Wassuk Spur faults that step left to the northwest. Associated moderately dipping faults have tilted Oligocene tuffs to the W or SW to the SW of the fault zone, and both E and W on the NW; based on offset of the Jurassic porphyry dike and slickensides, these faults were dominantly oblique-slip normal faults with WNW-ESE slip. No lateral offsets can be directly measured across the steeply dipping faults; however, they juxtapose different Mesozoicmore » metamorphic rocks and different thicknesses of Oligocene ignimbrites, suggesting significant lateral offset. Bingler's (1978) proposal that the White Mt. fault had left-laterally offset the White Mt. granite (WMG) from granite of Black Mountain (BMG) is unreasonable because the BMG intrudes the Wassuk Range diorite and contain biotite aplites, whereas the WMG intrudes metavolcanic rocks and contains tourmaline-muscovite aplites. « less

Some applications of unsaturated soil mechanics

After a brief review of a number of developments of unsaturated soil mechanics, the paper presents some applications to engineering problems. The first case involves the collapse of a residual soil in Brazil triggered by a water level increase caused by the filling of a dam reservoir. The second case analyzes the effects of rainfall on a natural slope in Ancona (Italy). The final case refers to the subsidence in the region of Ravenna related to the depletion of deep gas reservoirs. The ensemble of the cases described illustrates the potential of unsaturated soil mechanics concepts for the understanding and reproduction of observed field behaviour.
Preliminary Approach for a Prototype of Sustainable Antiseismic Dwelling in Nepal Based on the Historic Vernacular Tradition

The effects of the 2015 Gorkha earthquake in Nepal revealed deficiencies in the most recent vernacular architecture, which no longer uses wooden reinforcements due to national anti-deforestation laws. It also highlighted the shortcomings found in reinforced concrete architecture, which is generally scanty and poorly reinforced due to the high import cost of construction steel. The geography of Nepal has led to the development of a wide variety of vernacular architecture using local materials such as stone, brick or earth in the form of rammed earth and adobe walls [1]. Moreover, although its tradition in the construction of vaults is not as prominent as in neighbouring regions of India, Nepal has developed its own tradition in the construction of vaults and domes, which are generally self-supporting and made of brick or adobe with lime mortar. The design of a prototype of seismic house in Nepal aims to use a modular housing unit with rammed earth walls and/or walls made of materials recycled from previous earthquakes, as well as tile vaults with bamboo sleepers, and possibly vegetable fibre grids. These avoid the use of imported materials, favouring km0 and sustainable materials while following local tradition. Several potential housing units have undergone linear seismic analysis on finite element models, with variations in planimetric layout and the types of tile vault, from the simpler barrel vault to the sail vault. Both are analysed searching for the best shape in terms of seismic efficiency, evaluating stress and strain
Are dividens disappearing?. Mixed evidence from Europe

Recent empirical studies reported the phenomenon of low propensity of firms to dividend payment, concluding that companies have become less likely to pay dividends. In addition, most of these studies claim that investors’ expectations regarding dividend payments also decreased. We analyse the propensity to pay dividends in three European markets: Portugal, France and the UK. Although they are all European markets, they differ from each other for several reasons. Firstly, the UK is one of the largest European capital markets, whereas the French and Portuguese markets are smaller, especially Portugal. Additionally, these latter two markets are less intensively researched. Secondly, these countries differ in terms of ownership concentration. In Portugal and France ownership tends to be more concentrated than in the UK. Thirdly, Portugal and France are bank-based financing systems, whereas the UK is a market-based system. Finally, the legal rules covering protection of corporate shareholders are different in the three countries. We find evidence of the decline of firms paying dividends in Portugal and in the UK, but not in France. Moreover, we find some evidence that firms that pay dividends tend to be the ones of larger size and higher profitability, but we find no evidence of a significant relation between a firm’s growth and dividend payments.
Management of behavioural and psychological symptoms of dementia by an aroma‐massage with acupressure treatment protocol: A randomised clinical trial

AIMS AND OBJECTIVES This study evaluates the clinical effectiveness of a multicomponent aroma-massage with an acupressure treatment protocol and compared it to cognitive training for the management of behavioural and psychological symptoms of dementia. BACKGROUND Pharmacological interventions have been unsatisfactory in managing behavioural and psychological symptoms of dementia; thus, complementary and alternative medicine has been extensively researched to identify an adjunct safe and cost-effective intervention. DESIGN This randomised clinical trial utilised a three-arm parallel group design. Cognitive training was used as a conventional intervention to manage behavioural and psychological symptoms of dementia, whereas exercise was considered "treatment as usual" in this study; both were used as comparisons with the experimental protocol. There were three treatment groups: Group 1: aroma-massage with acupressure + exercise, Group 2: cognitive training + exercise and Group 3: aroma-massage with acupressure + cognitive training. METHOD Sixty older adults were recruited and randomly assigned to the three groups (20 each). Using the 29-item Chinese Version of the Cohen-Mansfield Agitation Inventory, Neuropsychiatric Inventory, Mini-mental State Examination and Barthel Index-20, the outcome measures were assessed at preintervention, postintervention and the 3-month follow-up to assess behaviour, Activities of Daily Living, cognition, and behavioural and psychological symptoms of dementia severity and distress. Multiple comparisons performed through repeated measures were analysed to detect between-group differences and within-subject differences, as well as the interaction effects between groups and times. RESULTS The Group 1 and 3 participants showed a significant reduction in the severity and distress caused by behavioural and psychological symptoms of dementia, whereas Group 2 did not demonstrate similar effects. CONCLUSIONS This clinical study suggests that aroma-massage with acupressure is as effective as cognitive training and can enhance cognitive training in reducing the severity and distress of behavioural and psychological symptoms of dementia. RELEVANCE TO CLINICAL PRACTICE Aroma-massage with acupressure may serve as an adjunct therapy to reduce behavioural and psychological symptoms of dementia. This therapy is safe, cost-effective and can be implemented by caregivers and family members who are not professionally trained.

Product Line Pricing in a Vertically Differentiated Oligopoly - La Tarification D’Une Ligne De Produits Dans Un Oligopole Verticalement Différencié

This paper examines the joint pricing decision of products in a firm’s product line. When products are distinguished by a vertical characteristic, those with higher values of that characteristic will command higher prices. We investigate whether, holding the value of the characteristic constant, there is an additional price premium for products on the industry and/or the firm frontier, that is, for the products with the highest value of the characteristic in the market or in a firm’s product line. We also investigate the existence of price premia for lower‐ranked products and other product line pricing questions. Using personal computer price data, we show that prices decline with the distance from the industry and firm frontiers, even after holding absolute quality constant. We find evidence that consumer tastes for brands is stronger for the consumers of frontier products (and thus competition between firms weaker in the top end of the market). There is also evidence that a product’s price is higher if a firm offers products with the immediately faster and immediately slower computer chip (holding the total number of a firm’s offerings constant), possibly as an attempt to reduce cannibalization. Finally, a product’s price declines with the time it is offered by a firm, suggesting intertemporal price discrimination. Ce memoire examine la decision conjointe de tarification des produits dans la ligne de produits d’une firme. Quand les produits se distinguent par une caracteristique verticale, ceux qui ont de plus grandes valeurs pour cette caracteristique commanderont de plus forts prix. On se demande si, gardant la valeur de cette caracteristique constante, il y a une prime additionnelle des prix pour les produits de l’industrie ou pour les produits de pointe de la firme (i.e., les produits avec la plus haute valeur de cette caracteristique dans le marche ou dans la ligne de produits de la firme). On examine aussi s’il existe une prime de prix pour les produits qui se classent moins bien ou d’autres questions sur la tarification des lignes de produits. En utilisant des donnees de prix pour les ordinateurs personnels, on montre que les prix chutent a mesure qu’on s’eloigne de la frontiere des produits de pointe pour l’industrie et la firme, meme si on garde la qualite absolue constante. Les resultats montrent que le gout des consommateurs pour les marques est plus fort pour les consommateurs des produits de pointe (et que la concurrence entre firmes est plus faible dans cette section du marche). On montre aussi que le prix d’un produit est plus eleve si une firme offre des produits avec une puce juste plus rapide et plus lente (tout en gardant le nombre total de produits de la firme constant) possiblement dans un effort pour reduire la cannibalisation. Enfin, le prix d’un produit decline a proportion que la periode de temps ou il est offert par une firme s’allonge, ce qui suggere qu’il y a discrimination intertemporelle par les prix.
Approaches to improving detection of invasive fish species in western Lake Erie through analysis of monitoring efficiencies and metrics of community distribution

APPROACHES TO IMPROVING DETECTION OF INVASIVE FISH SPECIES IN WESTERN LAKE ERIE THROUGH ANALYSIS OF MONITORING EFFICIENCIES AND METRICS OF COMMUNITY DISTRIBUTION by JOSHUA A. SOUTHERN May 2014 Advisor: Dr. Donna R. Kashian Major: Biological Sciences Degree: Master of Science Efficient monitoring programs are essential for the early detection of invasive species. The Ohio Department of Natural Resources (ODNR) monitoring program encompassing 21 years of fish survey data from western Lake Erie was evaluated using Chao biodiversity analysis to determine the efficiency and precision of collection strategies of trawl and gillnet sampling, at detecting rare or non-native species. Overall, ODNR sampling annually accounted for ~80% of extant fish species, leaving gaps in coverage where rare and invasive species may be overlooked and proliferate.Obtaining 90% efficiency would require an estimated doubling of previous sampling effort. Computer simulations calculating different proportions of trawl and gillnet sampling effort indicate an advantage to mixing collection strategies by reducing effort, and reveals a range of effective proportions concerning the two collection techniques. In addition, population trends for several species were evaluated to better elucidate strengths and weakness of current monitoring programs. These results enable an analysis of maximized sampling efficiency to provide earlier detection of future
Deglacial development of (sub) sea surface temperature and salinity in the subarctic northwest Pacif

Based on models and proxy data, it has been proposed that salinity-driven stratification weakened in the subarctic North Pacific during the last deglaciation, which potentially contributed to the deglacial rise in atmospheric carbon dioxide. We present high-resolution subsurface temperature (TMg/Ca) and subsurface salinity-approximating (δ18Oivc-sw) records across the last 20,000 years from the subarctic North Pacific and its marginal seas, derived from combined stable oxygen isotopes and Mg/Ca ratios of the planktonic foraminiferal species Neogloboquadrina pachyderma (sin.). Our results indicate regionally differing changes of subsurface conditions. During the Heinrich Stadial 1 and the Younger Dryas cold phases, our sites were subject to reduced thermal stratification, brine rejection due to sea-ice formation, and increased advection of low-salinity water from the Alaskan Stream. In contrast, the Bolling-Allerod warm phase was characterized by strengthened thermal stratification, stronger sea-ice melting, and influence of surface waters that were less diluted by the Alaskan Stream. From direct comparison with alkenone-based sea surface temperature estimates (SSTUk′37), we suggest deglacial thermocline changes that were closely related to changes in seasonal contrasts and stratification of the mixed layer. The modern upper-ocean conditions seem to have developed only since the early Holocene.

Build an arc (accounting resource center) and they will come…or will they?

Abstract The authors present one university’s experience creating drop-in, peer tutorial services for students in an introductory accounting class. First, data suggest that students most in need of tutoring support used the services the least. Second, findings appear to support the existence of self-selection bias: 40% of the students who visited the Accounting Resource Center had cumulative GPAs greater than 3.0. These students averaged more visits and spent more time than students who ultimately received a D, F, or W for the course. Results indicate the Accounting Resource Center was used disproportionately more by students who have an established history of success at the university.

The obliquity of Titan as evidence for the presence of a liquid ocean beneath the surface and perspectives for the determination of the ice shell thickness of Europa

A value of the obliquity of Titan,e'0.3◦, has been obtained from a study of Cassini radar images [1]. From radio tracking, the quadrupole field of Titan has been found to be consistent with a body in hydrostatic equilibrium, and the resulting moment of inertia, C, is about 0.34MR2[2]. The obliquity value is, however, not consistent with the moment of inertia because the 0.3◦obliquity value implies C= 0.55MR2, according to a study of the Cassini state generalised to a multi-frequency node precession for Titan , in which the ice outer shell is fully coupled with the interior. With a liquid water ocean beneath the ice shell, the shell is only partially coupled with the interior by gravitational, pressure and viscous torques, which may result in a different obliquity value.
Evaluation of infiltration rates within the Vistula River valley, central Poland

The Vistula river valley groundwater system has a strong hydraulic connectivity with the surface waters of the Vistula River. typically, it is dominated by infiltration, and may at the same time represent a transitional system, in which lateral baseflow discharge takes place from surrounding units (e.g. plateau) to the river valley. a relatively simple mechanism of infiltration represents one of the elements of a complex water circulation system in the valley unit. the recognition of the entire recharge mechanism in a valley unit allows indicating a variable but significant role of infiltration. Evaluation of the value of infiltration on a regional scale has been made for the Vistula River valley in the Kampinoski National Park (KNP) area. Data on the spatial distribution of infiltration, averaged for a particular time interval, are indispensable e.g. for balance calculations as well as for evaluation of groundwater vulnerability to contamination. Evaluation of infiltration into the groundwater system of the KNP area was made using the following methods: meteorological and empirical methods, water table fluctuation (wtF), runoff hydrograph sub-division (bFI), and numerical simulations.
