Software systems evolve over time due to changes in requirements, optimization of code, fixes for security and reliability bugs etc. Code churn, which measures the changes made to a component over a period of time, quantifies the extent of this change. We present a technique for early prediction of system defect density using a set of relative code churn measures that relate the amount of churn to other variables such as component size and the temporal extent of churn.Using statistical regressio ...
Zhang and Zhang argue that predictors are useless unless they have high precison&recall. We have a different view, for two reasons. First, for SE data sets with large neg/pos ratios, it is often required to lower precision to achieve higher recall. Second, there are many domains where low precision detectors are useful. ...
Based on power line carrier communication technology, a decentralized multi-agent system (DMAS)-based frequency control strategy is proposed and investigated in this study on an autonomous microgrid with communication constraints, where each agent can only communicate with its neighboring agents. Using the optimized average consensus algorithm, the global information (i.e., total active power deficiency of the microgrid) can be accurately shared in a decentralized way. Depending on the discovere ...
Retinoic acid (RA) is the form of vitamin A that controls differentiation and proliferation of epithelia. Our previous work established that normal breast epithelia synthesize RA from retinol, an ability retained by three immortalized but nontumorigenic cell lines but lost in five of six breast cell lines. In this work, we characterize the cause of this defect in one of the lines, the MCF-7 line. We have determined that the immortalized but nontumorigenic cell line, MTSV1.7, capable of synthesiz ...
BACKGROUND: Pregnancy-induced hypertension (PIH) is a pregnancy-specific condition that occurs after the 20 week of gestation. These physiologic changes can be aggravated by undernutrition. There are some evidence based on the importance of nutrient deficiency in developing this syndrome. Therefore, the aim of present study was to determine the nutritional risk factors for pregnancy induced hypertension in a group of pregnant women in Isfahan. METHODS: In this case-control study, we recruited 46 ...
As clock rates continue to rise, problems with signal integrity, cross-coupling, and radiation may render impractical the baseband metallic interconnects presently used in computers. A potential means to address this problem is to use bandpass wireless interconnects operating at millimeter-wave center frequencies. We have conducted experimental and finite-difference time-domain (FDTD) computational studies scaled to a 10 GHz center frequency of single-row and double-row waveguiding defects withi ...
While previous taxonomies for prefix adders have focused on the design space of such adders with fixed topologies (in terms of fanout, radix, logic depth, wiring tracks), our work considers the design space of reconfigurable prefix adders (with applications in fault-tolerant adder design) by introducing several new degrees of freedom in the design space. Fault tolerance in general requires redundancy, so we start with a redundant structure which is a superset of the entire family of prefix adder ...
The environment is packed with a large variety of particles, microorganisms and antigens, which are encountered by humans and animals via mucosal surfaces of the respiratory and gastrointestinal tracts. Inhaled or ingested particles can traverse these tracts and exit, or are taken up by epithelial and phagocytic cells. Either way, only a few, if any, of the particles escape unnoticed, with most being sensed by Toll-like receptors (TLRs) and nucleotidebinding oligomerization domain (Nod)–like r ...
Retrieving and analyzing information from software repositories and detecting dependencies are important tasks supporting software evolution. Dependency information is used for change impact analysis, defect prediction as well as cohesion and coupling measurement. In this paper we report our experience from extracting dependency information from the change history of a commercial software system. We analyzed the software system's evolution of about six years, from the start of development to the ...
A variety of ways has been established to detect defects found on printed circuit boards (PCB). In previous studies, defects are categories into seven groups with a minimum of one defect and up to a maximum of 4 defects in each group. Using Matlab image processing tools this research separates two of the existing groups containing two defects each into four new groups containing one defect each by processing synthetic images of bare through-hole single layer PCBs. ...
Autophagy in hypothalamic neurons regulates food intake in mice, according to Qingyuan Meng and Dongsheng Cai (J. Biol. Chem. doi:10.1074/jbc.M111.254417) and Susmita Kaushik et al. (Cell Metab. 14, 173–183). Meng and Cai found that chronic highfat feeding and obesity was associated with reduced expression of autophagy-related protein 7 (Atg7) and other markers of autophagic activity in the hypothalamus. Genetic knockdown of Atg7 by shRNA injection resulted in increased food intake and obesity ...

Three-dimensional system integration using Cu through-silicon-via (TSV) technology enables vertical interconnection of stacked dies. However, the large statistical distribution of plastic Cu extrusion, also known as Cu pumping, presents a serious reliability concern. Traditional finite element method (FEM) based thermo-mechanical modeling that neglects microstructure has been extensively attempted in order to identify the root cause of the extrusion, which yet remains unknown. This study utilize ...
Magnetic resonance is a wrell known tool for the investigation of atomic and molecular motions in solids and a large amount of work has been done in the past on this subject by studies of Zeeman (Ty/J spin-lattice relaxation time and dipolar line widths {To). More recently, the power of the NMR method has been still considerably improved bv the mea­ surements on rotating frame1,2 Tls and dipolar (jTh)) relaxation rates which are particularly sensi­ tive to extremely slowT spin motions in solid ...
Alpha-bsm ® is a first generation self-setting, injectable and moldable apatitic calcium phosphate cement (CPC) based on amorphous calcium phosphate (ACP). ACP was prepared using low temperature double decomposition technique, from a calcium solution (0.16 M), and phosphate solution (0.26 M) in a basic (pH~13) media.

Severa ...
In order to effectively differentiate all kinds of defects inside the composites, this paper carries out testing on the internal defects of three-dimensional (3d) braided composites by use of acoustic emission nondestructive detecting technology. It puts forward the processing method for acoustic emission signals for the internal defects of three-dimensional braided composites based on wavelet neural network (WNN). This method does wavelet transformation on real-time collected acoustic emission ...
At the same time harbour porpoises, that had died of a similar virus, appeared stranded on the beaches. Two years later another mass die-off occurred in the Mediterranean striped dolphin populations. The severe and lethal outcomes of the epidemics led many in the scientific community to believe that a contaminantinduced immune deficiency was responsible for the high mortality during the epidemic outbreaks. A p a t t e r n emerged in which seal populations in grossly polluted waters, like the Kat ...
Current paper proposes a new hierarchical approach to defect-oriented testing of CMOS circuits. The method is based on critical area extraction for identifying the possible shorted pairs of nets on the basis of the chip layout information, combined with logic-level test pattern generation. The novel contributions of the paper are a new bridging fault simulator and a test pattern generator, which are able to handle defects creating feedbacks into the circuit. As a preprocessing step, a combined s ...
Estrogen deficiency causes a marked bone loss by stimulating osteoclastic bone resorption. Recent studies on the role of estrogen in bone resorption have focused on the involvement of at least two cytokines, IL-1 and IL-6. It is well known that IL-1 stimulates osteoclastic bone resorptionin vitro andin vivo by inducing the differentiation of osteoclast precursors into mature osteoclasts and by stimulating their activity. On the other hand, we reported that IL-6 greatly stimulated the differentia ...
Objective: This study investigates the combination of platelet-rich plasma (PRP) or concentrated bone marrow aspirate (CBMA) with a biphasic collagen/glycosaminoglycan (GAG) osteochondral scaffold for the treatment of osteochondral defects in sheep.

The authors present an analysis of the fault tolerant properties and the effects of temperature on an exclusive OR (XOR) gate and a full adder device implemented using quantum-dot cellular automata (QCA) structures. A Hubbard-type Hamiltonian and the Inter-cellular Hartree approximation have been used for modeling, and a uniform random distribution has been implemented for the simulated dot displacements within cells. We have shown characteristic features of all four possible input configuration ...
As device sizes are downscaled to nanometer, Random Telegraph Noise (RTN) becomes dominant. It is indispensable to accurately estimate the effect of RTN. We propose an RTN simulation method for analog circuits. It is based on the charge trapping model. The RTN-induced threshold voltage fluctuation are replicated to attach a variable DC voltage source to the gate of a MOSFET by using Verilog-AMS. In recent decananometer processes, high-k (HK) materials are used in gate dielectrics to decrease the ...
BOne loss in osteoporosis is due to an imbalance between the formation and destruction of bone. This can occur either at the level~ of the individual turnover units, the BMU's (imbalance), or at different sites (uncoupling). The size of the negative balance will depend both upon the bone loss at the individual site, and upon the number of sites formed and destroyed (turnover). These two processes are dependent upon systemic modulators, among others hormones, upon mechanical factors, and upon loc ...

Inherited pyrimidine 5'-nucleotidase type-1 (P5'N-1) deficiency is the most frequent abnormality of red cell nucleotide metabolism causing non-spherocytic hemolytic anemia. We describe two novel mutations in two Italian patients affected by P5'N-1 deficiency. One mutation is a two base deletion that occurs at the splice site junction between intron 7 and exon 8 (c.396-397del AG); the second is an in-frame deletion of three adjacent bases (c.427-429del CAA), leading to deletion of glutamine 143. ...
The increasing demand for the use of solar energy as an alternative source of energy to generate electricity has multiplied the need for more photovoltaic (PV) arrays. With the growth of the PV manufacturing industry, automation for defect detection is seen as a great potential in ensuring the quality of these PV modules. Hotspot formation due to defects is detrimental to the performance of PV devices. Thus this research aims to detect and isolate hotspot areas in PV modules by applying two mach ...
The ability of velocity methods to describe changes of topology by creating defects like holes is investigated. For the shape optimization energy-type objective functions are considered, which depend on the geometry by means of state variables. The state system is represented by abstract, quadratic, constrained minimization problems stated over domains with defects. The velocity method provides the shape derivative of the objective function due to finite variations of a defect. Sufficient condit ...
Track for modern ballasted high speed railway lines typically uses continuous welded rail with continuous ballast. Continuous ballast is often specified over features involving discontinuity of track support including structural movement or expansion joints found in long railway bridges. Accelerated degradation of track geometry has been observed at these types of location, resulting in unplanned maintenance. A location was identified on a viaduct of an operational high speed railway, where a re ...
A company builds a software system capable of running a diesel engine in a week, and in one case over a weekend, as opposed to the full year that it used to take. Another company builds one of its typical systems with 13 software engineers instead of the more than 100 it once required, and at the same time decreases the systems defect rate ten-fold. Still another increases its software-intensive product offerings from four per year to 50 per year. Imagine being able to use one person to integrat ...
A reliable process making use of adaptive filtering, adaptive wavelet transform (AWT) and adaptive neuro-fuzzy inference system (ANFIS) is proposed for automatic identification of defect in the bearing. The process starts with denoising the signal using a filter designed from the noise part in the signal itself using the least mean square algorithm. Thereafter, AWT is applied to denoised signal to produce AWT scalogram. AWT scalogram clearly gives time location information corresponding to burst ...
Nonlinear feature extraction of speech signals has been the main concern of many researches in recent years. In this paper, feature extraction of phonemes using NPC (neural predictive coding) model is generalized to a combination of time and DCT domains. Two main ideas were proposed and evaluated in this paper. First, a frame-wise DCT-based NPC feature extractor is proposed to overcome the computational complexity deficiency of the system. The basis of this approach is the application of a DCT p ...
The anticoagulant, activated Protein C (aPC), possesses antithrombotic, profibrinolytic, antiinflammatory, and antiapoptotic properties, and the level of this protein is an important marker of acute inflammatory responses. While infusion of aPC improves survival in a subset of patients with severe sepsis, evidence as to how aPC decreases mortality in these cases is limited. Since a total deficiency of PC shows complete neonatal lethality, no animal model currently exists to address the mechanist ...

Previous studies have shown an association with a mutation in a gene mapped to chromosome 16 and Crohn’s disease. Recent publications have identified this gene as the NOD2 gene, which plays a role in the inflammatory responses triggered by bacteria. Clinically, antibiotics have been used for treating some Crohn’s patients. In the laboratory, animal models for inflammatory bowel disease (IBD) raised in germ-free environments often do not manifest their IBD. The NOD2 gene is therefore a fascin ...
Hemoglobin glycation is due to the prolonged exposure to hyperglycemia resulting from defects in insulin secretion. Ketoacidosis is another complication associated with insulin deficiency in diabetes mellitus. Furthermore, it was recently demonstrated that glycation occurs in vitro with bicarbonyl compounds derived from fatty acid oxidation. To study the relationship between the glycation of hemoglobin and diabetic ketoacidosis, we tested the in vitro formation of HbA1 by acetone and -hydroxibut ...
230-keV 28Si ions were implantated into Si( 100) at room temperature with doses from 1014 to 101*/cm2. The samples were analyzed by x-ray double crystal diffractometry and 2-MeV 4He ion channeling spectrometry. The implanted layer has a parallel lattice spacing equal to that of the unimplanted substrate. The perpendicular lattice spacing is larger than that of the unimplanted substrate and is proportional to the defect concentration extracted from the channeling measurement. Both the perpendicul ...
This case report describes the treatment of an external infection related root resorption in a maxillary left central incisor which perforated the root canal apical to the cervical area.
