Anticipated House Purchases and Household Consumption

This paper evaluates how anticipated purchases of housing a ect households' consumption of non-durable goods. I build a heterogeneous agent model in which households save in liquid assets and illiquid housing, where the latter can be used as collateral for borrowing. I show that it is able to replicate the empirical distributions of income and wealth within the US economy. In the model there is substantial heterogeneity in households' marginal propensities to consume. Households with a high probability of buying housing stock lower their consumption of nondurable goods in anticipation of being credit constrained after their purchase. This results in households with low, even negative, marginal propensities to consume. I verify the model's predictions using micro-data from the PSID to show that (i) consumption falls in anticipation of, and after, changes in the stock of housing and (ii) households who are planning on purchasing housing have negative marginal propensities to consume. Finally, I use this model to examine the general equilibrium e ects of tax credits for rst home buyers and show that they lead to decreases in aggregate consumption. JEL codes: D14 , E21, E62.
Classifying and quantifying parameter nonlinearity in biological models

Models of biological systems typically include many parameters. Furthermore, the model behavior often responds to changes in these parameters in highly nonlinear ways. This nonlinear response is responsible for many of the unique emergent behaviors of biological systems. We discuss how model nonlinearity can be both quantified and classified. We consider the tensor of model second derivatives, i.e., the vector of Hessian matrices for each model prediction or alternatively the Jacobian of the Jacobian matrix. We use a higher-order singular value decomposition to identify the principal parameter combinations exhibiting the greatest nonlinearity (generalizations of singular vectors) and quantify this nonlinearity using generalizations of singular values. We further classify types of nonlinearity by decomposing the second derivative tensor into geometrically motivated components, including extrinsic, intrinsic, and parameter-effects nonlinearity. We discuss applications to model interpretation as well as for numerical methods.
anillysis of mitochondrial DNA from cytoplasmic malesterile lines of pearl millet

Mitochondrial DNA (mtDNA) from 13 cytoplasmic male-sterile (crns) lines from diverse sources were characterizcd by Southern blot hybridization to pearl millet and maize mtDNA probes. Hybridization patterns of mtDNA digcstcd with PstI, BunHI, S~ttaI or XkoI and probed with 13.6-, 10.9-, 9.7or 4.7-kb pearl millet mtDNA clones revealed similarities among the crns lincs 5141 A and ICMA I (classified as the S-A1 type of cytoplasm based on fertility restoration patterns), PMC30A and ICMA 2. The remainingcms lines formed a distinct group, within which three subgroups were evident. Among thc maize mitochondiral gene clones used, the cox1 probe revealed two distinct groups of cytoplasms similar to the pearl millet mtDNA c! ones. T heutp9 probe differentiated thccms line 81 A4, derived from P. glaucual subsp. taonodii, while the cox11 gene probe did not detect any polymorphism among the crns lines studied. MtDNA digested with BalttHI, PsrI or XhoI and hybridized to the atp6 probe revealed distinct differences among the crns lines. The maize atp6 gene clone identified four distinct cytoplasmic groups and four subgroups within a main group. The mtDNA fragments hybridized to the atp6 gene probe with differing intensities, suggesting the presence of more than one copy of the gene in different stoichiometries. Rearrangements involving the cox1 and/or rrn18-rrn5 genes (mapped within the pearl millet clones) probably resulted in the S-A1 type of sterility.

EFFECT OF DIETARY SUPPLEMENTATION WITH CHESTNUT AND GRAPE POMACE EXTRACTS ON GROWTH PERFORMANCE, NUTRIENT DIGESTIBILITY AND MEAT QUALITY OF RABBITS

The present study aimed at evaluating the effect of the dietary supplementation with two high-tannin extracts (chestnut vs. grape pomace) at two inclusi on levels (0.2% vs. 0.4%) on growth performance, nutrient digestibility, and meat quality in growing rabbits. A total of 270 crossbreed rabbits were randomly divided into 5 experimental groups and fed from weaning to slaughter (30 to 66 d of age) with: control diet (B); diets supplemented with 0.2 % or 0.4% of chestnut extract (C2 and C4, respectively), diets supplemented with 0.2% or 0.4% of grape pomace extract (G2 and G4, respectively). The mortality rate was very low (0.4 % on average) without differences among groups. Growth performance was not affected by the dietary reatments. In the post-weaning period, the digestibility of crude protein was higher in G2 and G4 groups compared to the C4 group (+2.9%; P<0.001). The digestibility of ether extract was lo wer in rabbits fed diet C4 compared to the others (P<0.001). In the fattening period, the digestibili ty of dry matter (+3.1%), fibre fractions and gross energy was higher in rabbits fed diet G4 with respe ct to the control group (0.05<P<0.001), whereas the digestibility of crude protein was the lowest with diet C4 (P<0.001). Slaughter weight, cold carcass, and dressing percentage averaged 2664 g, 1618 g and 60.8%, respectively, without significant differences among groups. Meat pH, colour indexes, and oxidative status were not modified by the dietary treatments. In conclusion, both chestnut an d grape pomace extracts rich in tannins can be used as feed additives in diets for growing rabbits at i nclusion levels ranging from 0.2% to 0.4% without negative effects on growth performance, slaughter r esults, and meat quality traits. However, the chestnut extract reduced nutrient digestibility at the highest supplementation rate during the postweaning period, whereas grape pomace extract increa sed nutrient digestibility at both rates in the pos tweaning and fattening periods.
Improvised convolutional auto encoder for thyroid nodule image enhancement and segmentation

Thyroid ultrasonography and thermography are a widely used clinical technique for nodule diagnosis in thyroid regions. However, it remains difficult to detect and recognize the nodules due to low contrast, high noise, and diverse appearance of nodules. To alleviate doctors’ tremendous labor in the diagnosis procedure, we advocate a machine learning approach to the detection and recognition tasks in this paper. Moreover, this research mainly focuses on segmenting the image and finding the probable region. In this research work an improvised convolutional auto encoder (ICAE) is introduced for segmenting the image and finding the probable region of thyroid gland and it enhances image. ICAE comprises various layer and mechanism, each having their own task. Apart from the traditional approach, skip connection is applied for the image enhancement and dual frame is introduced for better feature extraction. Further optimization technique is used for increasing the learning rate. ICAE is evaluated considering digital database thyroid image (DDTI) dataset with performance metrics like accuracy, true positive rate, false positive rate, dice coefficient and similarity index (SI); also, comparative analysis is carried out with various existing model and proposed model simply outperforms the existing model.
A High Gain Antenna with DGS for Sub-6 GHz 5G Communications

This paper introduces the design of a high-gain wideband microstrip patch antenna for sub-6 GHz 5G communication. The proposed antenna integrates a novel defected ground structure (DGS) for achieving the wide bandwidth. The ground plane uses a triangular strip inserted into the ground plane to improve the performance of the antenna. It also uses the reflective plate to concentrate the side lobes and minimise the production of the back lobe, thereby boosting the main lobe of the radiated signal and thus increasing the gain of the proposed antenna. The proposed antenna uses the FR-4 epoxy substrate with an inset feed technique in its design. The simulation and optimisation of the proposed antenna were carried out with CST Microwave Studio Suite. The antenna design is compact with a dimension of 28:03 23:455:35mm3 and a maximum gain and directivity of 6.21 dB and 7.56 dB respectively, with a radiation efficiency of about 80%. The proposed antenna operates from 4.921 GHz to 5.784 GHz, which covers the 4.9 GHz-5.8 GHz of the sub-6 GHz 5G communications spectrum. Fabricated and measured result of the antenna confirm simulated results.
Differences in Risk Conception and Differences in Technological Culture

How is it possible that the USA failed to keep New Orleans dry, when large parts of the Netherlands can exist below sea level? This question, with all its implicit rhetoric about the big and mighty Americans and the small and weak Dutch, generated a flock of American expeditions to the Netherlands in the aftermath of the flooding of New Orleans by hurricanes Katrina and Rita in 2005. The big US television networks, channels such as National Geographic, and political delegations, including the Louisiana governor and members of the US Congress, visited the Netherlands within a few months after the flooding, and all parties returned with spirited reports of how the Americans could learn from the Dutch. Does this suggest that the US Army Corps of Engineers is less able than the Rijkswaterstaat engineers in the Netherlands? I will argue that something else is going on: that the difference is not one of expertise and competence. In this paper I compare the styles of US and Dutch coastal engineer ing, and argue that they express different conceptions of risk management in relation to flooding. These differences can, perhaps, be explained by ref erence to the wider technological cultures of both countries, rather than to the specific engineering cultures. The core of my analysis, however, is aimed at the styles of coastal engineering. In this paper I am not interested in blaming artefacts or humans - levees/dikes1 and warning systems - or politicians or engineers involved in their design or maintenance. My con jecture is that even had everyone and everything functioned effectively, the historical style of American coastal engineering would encourage accepting the kind of flooding that occurred after Katrina.
Matching with Compatibility Constraints

The Canadian medical residency match has received considerable attention in the Canadian medical community as several students go unmatched every year. Simultaneously, several residency positions go unfilled, largely in Quebec, the Francophone province of Canada. The Canadian match is unique in that positions are designated with a language restriction, a phenomenon that has not been studied or described priorly in the matching literature. To study this phenomenon, we develop the model of matching with compatibility constraints, where based on a binary characteristic, a subset of students is incompatible with a subset of hospitals. We show that while the deferred acceptance algorithm still yields a stable matching, some desirable properties from standard two-sided matching are lost. For instance, we show that if the number of residencies exceeds the number of students, some students can yet go unmatched. We also investigate a dynamic game where unmatched positions are re-advertised without language restriction. The model can be generalized to other instances of the stable marriage problem.

As a result, it can be calculated by software the coefficient of friction using the data got completing the purpose of the tribotester machine.
Supporting Young People on the Autism Spectrum: Analyzing the Effectiveness of Components of Habit Reversal Treatment

Habit Reversal Treatment (HRT) has been used successfully to reduce nervous habits and tics in neuro-typical children and adults. It has not been researched extensively with regards to the restricted and repetitive behaviors that are part of a diagnosis of autism. This paper reports on the effectiveness of each of the three main components of HRT for young people on the autism spectrum. The awareness training procedure was effectively used in the treatment of encopresis; the competing response procedure effectively used in addressing vocal tics; and the social support procedure was effectively used for caregiver training to enhance overall treatment outcomes. Results are discussed in the context of evidence-based practice. International Journal of Autism and Related Disabilities Majchrzak JD and Dillenburger K.

Determining the Optimal Frequency of Ground Penetrating Radar for Detecting Voids in Pavements

PURPOSES : The objective of this study is to determine the optimal frequency of ground penetrating radar (GPR) testing for detecting the voids under the pavement. METHODS : In order to determine the optimal frequency of GPR testing for void detection, a full-scale test section was constructed to simulate the actual size of voids under the pavement. Voids of various sizes were created by inserting styrofoam at varying depths under the pavement. Subsequently, 250-, 500-, and 800-MHz ground-coupled GPR testing was conducted in the test section and the resulting GPR signals were recorded. The change in the amplitude of these signals was evaluated by varying the GPR frequency, void size, and void depth. The optimum frequency was determined from the amplitude of the signals. RESULTS: The capacity of GPR to detect voids under the pavement was evaluated by using three different ground-coupled GPR frequencies. In the case of the B-scan GPR data, a parabolic shape occurred in the vicinity of the voids. The maximum GPR amplitude in the A-scan data was used to quantitatively determine the void-detection capacity. CONCLUSIONS: The 250-MHz GPR testing enabled the detection of 10 out of 12 simulated voids, whereas the 500-MHz testing allowed the detection of only five. Furthermore, the amplitude of GPR detection associated with 250-MHz testing is significantly higher than that of 500-MHz testing. This indicates that 250-MHz GPR testing is well-suited for the detection of voids located at depths ranging from 0.5~2.0 m. Testing at frequencies lower than 250 MHz is recommended for void detection at depths greater than 2 m.
Relationship between Serum Hepatitis B Virus-RNA Levels and Histopathological Assessment in Chronic Hepatitis B Patients Treated with Entecavir

Hepatitis B Virus RNA (HBV RNA) is a new serum marker and a direct product of the covalently closed circular DNA (cccDNA). Entecavir (ETV) has been widely used for the treatment of Chronic Hepatitis B Virus (CHB) infection. The following study investigates the correlation between HBV RNA and histopathological changes in the liver, in response to ETV therapy. A cross-sectional set of serum and liver biopsy samples was obtained from patients treated with ETV. The correlations between serum HBV-RNA concentration and levels of peripheral viral replicative forms, as well as histological scores were analyzed before and after treatment. At baseline, serum HBV-RNA (5.807 ± 2.503 log 10 copies/ml) was detected in 29 patients. These levels were correlated with the serum HBV-DNA level (5.828 ± 1.586 log 10 IU/ml) and HBeAg levels (median, 11.733; 25%~75% range, 0.311~385.75 S/CO). Nevertheless, low correlation was found between the serum HBV-RNA, ALT levels and the histological scores for grading and staging of the liver. Moreover, after 53 ± 5 weeks of treatment, the concentrations of serological indicators have significantly decreased, and the characteristics of histology have also improved. When grouped according to the pathological changes, no statistical differences in HBV RNA levels were detected between groups, before or after treatment. To conclude, the serum HBV-RNA levels reflect the intrahepatic viral transcriptional activity and when combined with liver histopathological analysis they can more precisely reflect the effect of ETV therapy.
Determination of quercetin in dietary supplements by isocratic RP-HPLC method

Quercetin is a natural flavonoid found abundantly in vegetables and fruits. It shows antioxidant, anti-inflammatory, antihepatotoxic, antiallergic, antidiabetic and antiviral activity. Increasingly popular dietary supplements containing quercetin require critical examination of their quality. The aim of this study was to develop a simple and accurate HPLC method for quercetin determination in dietary supplements. Chromatographic separation was achieved by isocratic method, using a Purospher STAR® RP-18 reverse-phase column (150 x 4.6 mm i.d., particle size 5 μm), a mobile phase composed of acetonitrile and water (acidified to pH 3.0), in a ratio of 30:70 (V/V), run at a flow rate of 1.1 mL/min. The column temperature was kept at 30 °C. The DAD detector was set at 257 nm and 375 nm. The injection volume was 20 μL. Isopropanol was used as a solvent. The method was validated by determining system suitability, specificity, linearity, range, limit of detection and quantification, accuracy, precision, and robustness. It is characterized by simple preparation, good precision (RSD ˂ 2%) and good analytical yield (100.09% and 100.29% at 257 nm and 375 nm, respectively). The limit of detection and quantification were 0.00071 μg/mL and 0.00215 μg/mL at 257 nm, and 0.00078 μg/mL and 0.00236 μg/mL at 375 nm, respectively. The system suitability test showed that method performance is similar at both wavelengths. This method can be recommended for routine analysis of dietary supplements containing quercetin in food quality control laboratories. Keywords: quercetin, HPLC, dietary supplements, flavonoid
FGV-EESP - Econometrics III Hodrick-Prescott and Hamilton’s Filter: An Application

Measurement of the business cycles is very essential for the study of business cycles in macroeconomics. In this context the main issue is how to separate the trend component from the cyclical component. The purpose of this article is to give a quick characterization of two techniques to filter economic time series: the HP filter and Hamilton’s regression filter. Both intend to decompose a time series in the above mentioned components. Furthermore, I will apply these methods on U.S. Employment data (to reproduce Hamilton’s “Why You Should Never Use Hodrick-Prescott Filter”) and I will compare both filtering methods, having on mind the drawbacks of each.
How Do Energy Psychology Modalities Work? An Energy-Based Theoretical Perspective

Energy Psychology (EP) modalities, integrative methods that strategically involve accessing human energy for therapeutic purposes, enjoy a rich and diverse evidence base. As such, many attempts have been made to explain how they work. Explanations have primarily utilized a biological basis for explicating the mechanisms by which EP may function. These contributions are extremely valuable; however, none have been able to offer a fully satisfactory understanding of the efficacy of EP. The currently accepted theoretical model is not robust enough to explain a number of EP effects, and acupoint stimulation remains a confounding factor even though research shows it is an essential component in predominant EP modalities. In many professional EP trainings, negative emotions are said to be caused by a block in the meridian system, so energy-based theory is invoked but not well explained. Since acupoints are part of the meridian system that distributes vital energy (sometimes called qi) and are therefore energy-based, employing an energy-based perspective for modeling EP could advance theoretical understanding. In this paper I offer an energy-based perspective grounded in Tiller’s multidimensional model. I describe how main components of the model function and apply those to EP, specifically with regard to acupoint stimulation. The objective is to propose a perspective that includes existing theoretical models and extends our understanding of the mechanisms by which EP may work by expanding the theoretical base, contributing to a model with increased scope and explanatory power.
Effect of microencapsulation on quality attributes of fish oil

The fish oil being one of the most important sources of essential fatty acids is considered as nutritional supplement for humans. It is also important to store the fish oil in such a way that it does not develop any rancid flavor and leads to its spoilage. A physical barrier is used to protect fish oil from oxygen, light and temperature difference such that the oxidation of the fish oil can be avoided. In the present study the fish oil microencapsulates were prepared using three different concentration of sodium alginate, 5% (T1), 7% (T2), 9% (T3) and the fish oil without sodium alginate T0 (C) was taken as control and the 4 samples were analyzed for its sensory characteristics and biochemical properties for 15 days at ambient temperature stored in glass bottle. According to biochemical analysis and sensory evaluation, the T1 sample of a fish oil microcapsules prepared with 5% of sodium alginate was most suitable for microcapsule preparation.
Delta Keyword Transformer: Bringing Transformers to the Edge through Dynamically Pruned Multi-Head Self-Attention

Multi-head self-attention forms the core of Transformer networks. However, their quadratically growing complexity with respect to the input sequence length impedes their deployment on resource-constrained edge devices. We address this challenge by proposing a dynamic pruning method, which exploits the temporal stability of data across tokens to reduce inference cost. The threshold-based method only retains significant differences between the subsequent tokens, effectively reducing the number of multiply-accumulates, as well as the internal tensor data sizes. The approach is evaluated on the Google Speech Commands Dataset for keyword spotting, and the performance is compared against the baseline Keyword Transformer. Our experiments show that we can reduce ~80% of operations while maintaining the original 98.4% accuracy. Moreover, a reduction of ~87-94% operations can be achieved when only degrading the accuracy by 1-4%, speeding up the multi-head self-attention inference by a factor of ~7.5-16.
