Practical regression test selection with dynamic file dependencies (2015)

Regression testing is important but can be time-intensive. One approach to speed it up is regression test selection (RTS), which runs only a subset of tests. RTS was proposed over three decades ago but has not been widely adopted in practice. Meanwhile, testing frameworks, such as JUnit, are widely adopted and well integrated with many popular build systems. Hence, integrating RTS in a testing framework already used by many projects would increase the likelihood that RTS is adopted. We propose a new, lightweight RTS technique, called Ekstazi, that can integrate well with testing frameworks. Ekstazi tracks dynamic dependencies of tests on files, and unlike most prior RTS techniques, Ekstazi requires no integration with version-control systems. We implemented Ekstazi for Java and JUnit, and evaluated it on 615 revisions of 32 open-source projects (totaling almost 5M LOC) with shorter- and longer-running test suites. The results show that Ekstazi reduced the end-to-end testing time 32% on average, and 54% for longer-running test suites, compared to executing all tests. Ekstazi also has lower end-to-end time than the existing techniques, despite the fact that it selects more tests. Ekstazi has been adopted by several popular open source projects, including Apache Camel, Apache Commons Math, and Apache CXF.

The crystal structure of the <i>B</i>-site ordered complex perovskite Sr(Yb<sub>0.5</sub>Nb<sub>0.5</sub>)O<sub>3</sub> (1999)

The room-temperature crystal structure of the B-site ordered complex perovskite strontium ytterbium niobate, Sr(Yb(0.5)Nb(0.5))O(3) [monoclinic, Z = 2, P2(1)/n (set 2), a = 5.79095 (8), b = 5.82210 (7), c = 8.20358 (12) Å, beta = 90.126 (1) degrees, with final R(wp) = 0.0595, R(Bragg) = 0.0203 for the neutron profile and R(wp) = 0.0832, R(Bragg) = 0.0193 for the X-ray profile, respectively], was determined by X-ray powder diffraction, high-resolution neutron powder diffraction and transmission electron microscopy. This compound shows a slight triclinic distortion from the prototype doubled cubic perovskite cell as a result of an a(-)a(-)c(+)-type oxygen octahedral tilting distortion. It is also shown that the site ordering of the different species of B-site cations, Yb(3+) and Nb(5+), inherently leads to a difference between the volumes of the YbO(6) and NbO(6) octahedra. This volume difference is shown to inevitably inhibit the rigid rotation of octahedra.
Improving the Scavenged Power of Nonlinear Piezoelectric Energy Harvesting Interface at Off-Resonance by Introducing Switching Delay (2014)

This paper presents two interface circuit designs that improve the piezoelectric energy harvesting performance at offresonance. Complex impedance matching at different frequencies is achieved by introducing delay into the conventional switching methods. The proposed techniques can also be used in other applications, such as electromagnetic energy harvesting. The system is analyzed using equivalent impedance at fundamental of operating frequency. Design considerations such as two possible modes of operation, sensitivity to voltage and timing errors, loss due to nonlinear operations, and conduction loss of switches are detailed. As compared with the conventional methods, analytical results show that, with the electromechanical coupling coefficient k2e of 0.076 and the mechanical damping ratio ζm of 0.02, the proposed techniques can improve the 3-dB bandwidth by 76% with a flipping quality factor of 10. Experimental results with a commercially available piezoelectric device show a 23% improvement in 3-dB bandwidth and a 66% improvement in extracted power with 5% of frequency mismatch.
Deuterated Water Effects on Acid Ionization Constants (1963)

Linear relations of the form DeltapK = pK(D) - pK(H) = a + b pK(H) relating ionization constants of acids in light and heavy water must have the same slope b for any kind of acid unless the previously unconsidered charge type is important or this equation is not valid.
Generation of high-power broad-band microwave pulses by picosecond optoelectronic technique (1989)

A single-picosecond GaAs photoconductive switch is used to pulse excite a microwave resonant cavity, thus generating a variety of RF (radiofrequency) waveforms with picosecond synchronization. The length of the transmission line that connects the photoconductive switch and the cavity and the strength of input/output cavity coupling elements provide for continuous variation of the frequency distribution of the generated RF power. The generation of greater than 7-kW broadband microwave bursts is demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bed Status Detection for Elder-Care Center (2009)

Elder-care is a very important issue in many developed countries such as U.S., Japan, England and Taiwan. In this paper, we focus on the bed status detection (BSD) with single IP camera for the chronic ailment and act slowly elders in the elder-care center (EC). Based on simple and fast motion estimation (ME) and binary area matching (BAM) algorithms, we can automatically remind the professional nurse which one of six elders will go to or leaving bed in a room. Simulation results show that we have 95% detection rate to assure the elders need our assistance immediately.
Inherited thrombocytopenia with thrombasthenia (1968)

A family with congenital thrombocytopenia is described through four generations where the mode of inheritance appears to be an autosomal dominant. Spontaneous bruising of varying severity, menorrhagia, and profuse bleeding at operation necessitating transfusion were predominant in the history. Platelet function tests were performed on the various patients. Platelet aggregation by adenosine diphosphate (ADP) was found to be defective, though liberation of platelet factor III and platelet thromboplastic function were found to be normal when corrected for deficient numbers.
Activity-induced adaptations in skeletal muscles of iron-deficient rabbits (1988)

The purpose of this study was to determine whether severe iron deficiency alters the adaptive response of skeletal muscle fibers to a sustained increase in tonic contractile activity. Seven weanling rabbits consumed a low iron diet and underwent phlebotomy twice weekly for 6 mo, resulting in severe anemia (mean Hb 5.5 g/dl). Compared with control animals, tibialis anterior skeletal muscles of iron-deficient animals exhibited reduced concentrations of cytochrome c (4.4 +/- 0.7 vs. 8.6 +/- 0.7 nmol/g tissue; P less than 0.01), and reduced activities of citrate synthase (83 +/- 10 vs. 133 +/- 13 mU/mg protein; P less than 0.01) and cytochrome-c oxidase (2.2 +/- 0.2 vs. 3.6 +/- 0.5 U/mg protein; P less than 0.05). In these muscles mitochondria were swollen and displayed deformed cristae. Less severe biochemical abnormalities were observed in cardiac and soleus skeletal muscles. Ten days of continuous electrical stimulation of the motor nerve supplying anterior compartment muscles of iron-deficient rabbits increased expression of mitochondrial proteins: cytochrome c was increased to 154% of control levels (P less than 0.05), and cytochrome-c oxidase and citrate synthase activities were increased to 199 and 272% of control levels, respectively (P less than 0.005). In addition, electrical pacing increased the fractional volume of mitochondria observed by electron microscopy and reduced the activity of aldolase A by 28% (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
Inhibition of Ribosomal A Site Functions by Sporangiomycin and Micrococcin (1975)

Sporangiomycin and micrococcin inhibit the binding of aminoacyl-transfer ribonucleic acid into the ribosomal A site in intact bacterial protoplasts. They also prevent the assembly of [ribosome-elongation factor G-guanine nucleotide] complexes in vitro and compete with [(35)S]thiostrepton for ribosomal binding sites. We conclude that micrococcin and sporangiomycin block the ribosomal A site in the vicinity of the complex guanosine triphosphatase center and so resemble thiostrepton in their modes of action.
THE POLLEN-STIGMA INTERACTION IN THE GRASSES. 7. POLLEN-TUBE GUIDANCE AND THE REGULATION OF TUBE NUMBER IN ZEA MAYS L. (1985)

The stigma of Zea mays can support the hydration and germination of considerable numbers of pollen grains, yet, in general, only one tube enters the micropyle to effect fertilisation. The numbers are reduced at various points in the pollen tube pathway, (1) by competition on the receptive trichomes and in the transmitting tracts, (2) by elimination of late-entering tubes at the stigma abscission zone, (3) at a constricted zone of the transmitting tracts in the upper ovary wall, and (4) in the vicinity of the micropyle. The control imposed at the abscission zone is higly effective. The entry of the first few tubes into the ovary wall induces a loss of turgidity of the cells of the zone and a disruption of the vasculation, and thereafter further tubes are irrevocably blocked in the main body of the stigma. The device maximises the period available for pollen capture and yet provides for the strict regulation of the number of tubes ultimately entering the ovary once pollination has taken place. Pollen tubes enter the ovary cavity by breaking through the inner epidermis of the ovary wall, which, like the contiguous inner integument, bears a thin discontinuous cuticle. Further passage is between the inner epidermis and the integument. Growth is irregular, but not wholly random, the tubes orienting themselves in the general direction of the micropyle following lines demarcated by the elongated cells of the epidermis and the integument. Almost throughout the pollen tube pathway, the cells in the vicinity show characteristics suggestive of a secretory function. The significance of this for pollen tube nutrition and guidance is briefly discussed.
The Neurosurgical Alleviation of Parkinsonism (1956)

This book will undoubtedly be widely read. Unfortunately paralysis agitans is a widespread and disabling condition. As there has been no truly satisfactory treatment for this chronic disease, many of its victims will look hopefully to the possibility of relief that is held out here. One of the barriers to investigating this condition lies in the fact that the disease has never been produced in animals and cannot, therefore, be studied by investigations in laboratory animals. Observations regarding the condition, its cause, pathological physiology, and treatment, must be made on man himself. It is notoriously difficult or impossible to conduct human investigations with the same scientific care that can be exerted with the laboratory animal. This is all the more reason why observations on human beings should be even more painstakingly made than those in the experimental laboratory. Unfortunately this book and the material recorded here do not meet that

High Density Data Storage on Ultraviolet Sensitive Tape (1974)

A novel recording material for optical data storage has been developed. On this material information can be recorded permanently by means of ultraviolet light and read out by visible light, and no developing or fixation process is required. Immediate control reading is possible. With a tape of this material, experimental investigations were performed concerning the design of a bit-by-bit storage system. The results confirm that excellent specifications are attainable by using a simple way of light deflection and tape guidance and a new principle of readout: Storage density of at least some Mbits/cm(2) at transfer rates for recording and reading up to at least some Mbits/sec and immediate control readout.
Construction of an atomic force microscope and application of atomic force microscopy and scanning tunneling microscopy in surface chemistry (2007)

A new force detector for atomic force microscope measurements is presented. A tip carrying an organic monolayer is covered by a thin metal layer that forms a tunneling gap which can be modulated by the surface forces. This arrangement eliminates the adjustment problems of the usual atomic force microscopy devices. Several experimental methods of tip preparation are discussed. — Scanning tunneling microscope images of adsorbed monolayers of n-octadecyl — trichlorosilane, tetraethyleneglycol laurylether, and n-hexadecane are presented.

The use of benzotriazole as a corrosion inhibitor for copper (1970)

Benzotriazole is a specific corrosion inhibitor for copper and copper alloys. It is now widely used in industry to reduce the corrosion of these alloys under both atmospheric and immersed conditions. Corrosion of copper may produce a surface stain or tarnish, pitting of surfaces of pipes or promote pitting of other metals, such as aluminium, which are in contact with dissolved copper in the water. Benzotriazole is used to reduce these forms of attack and the methods by which it is applied are discussed in this paper.
TCP Kay: An end-to-end improvement to TCP performance in lossy wireless networks using ACK-DIV technique & FEC (2015)

Wireless networks have evolved considerably in the last decade and the world has seen an exponential increase in the number of mobile device users. The performance of the wireless networks has become a critical factor and researchers nowadays are trying to bring out even the slightest increase in network performance wherever possible. TCP, which is the most dominant transport protocol of the Internet, fails to perform well in lossy wireless networks because it cannot differentiate congestion losses from non-congestion losses. This paper aims to improve the performance of TCP in lossy wireless networks and the resulting protocol is termed as TCP Kay. The major contributions of TCP Kay are: (1) it uses a modified ACK-DIV (Acknowledgment Division) technique for combating the loss of acknowledgement packets (ACKs) on the reverse path and (2) it combines the modified ACK-DIV technique with FEC to further enhance the robustness of data transmission in lossy wireless networks. The performance of TCP Kay has been studied using ns-2 and the same has been compared with TCP Reno with SACK (TCP SACK) and TCP Westwood+ (TCPW+). Results show that TCP Kay outperforms other TCPs in terms of goodput, received/sent ratio and packet drop rate in various wireless scenarios with up to 5% packet error rate.
Lifecycle based study framework of software evolution (2010)

Software evolution is characterized by its changing in accord with environment and requirement. It is one of the most difficult and important problems of software. From the runtime perspective, it includes two types: static evolution and dynamic evolution. Static evolution is mainly implemented by human static intervention and analysis. Dynamic evolution is based on the runtime evolution of software, mainly characterized as software self-adapting to environment. This paper presents a change-tracing model that regards the change as the starting point and focuses on software evolution in OO paradigm. It illustrates the change transmission and implementation process during the whole software lifecycle. Concerning the similarity between the change transmission process and the software lifecycle, a research framework of software evolution is proposed. This framework integrates all elements that are involved in the change transmission process, such as scenario, object, component and SA (Software Architecture). Based on this framework, the research of software evolution will be more effective and ties in dynamic evolution. At the end of paper, it gives some detailed discussion of key problems of software evolution in the framework and the corresponding solvability ideas.

Accessibility Analyzer: Tool for New Adaptations in Government Web Applications to Improve Accessibility (2017)

The “Outline for All” has turned into a very popular principle during the most recent years. Be that as it may, the advancement of products, services, and applications that are accessible by all individuals including diverse capacity is an exceptionally troublesome task. Web accessibility guidelines and techniques concentrates on reasonable utilization of alternative techniques and components for introducing the information and encourage the user communication paying little respect to their capacities. Web developers plays important role in development of accessible websites. Lamentably, a huge number of sites do not follow the accessibility standards. This paper aims to create an application which reports the results of accessibility issues found in the websites. The proposed accessibility analyzer is able to analyze Government websites and generate the results automatically. The result uncovers that the number of the government sites don't meet the suggested priority conformance level absolutely and disregard to consent to the principles of the WCAG(Web Content Accessibility Guidelines) 2.0. Critical work ought to be finished with a particular ultimate objective to make these web sites of Government destinations as the best-watched illustrations. This new approach could be profitable to upgrade the level of accessibility of various government websites.
Influence of a dietary fiber on development of dimethylhydrazine‐induced aberrant crypt foci and colon tumor incidence in wistar rats (1994)

Formation of aberrant crypt foci (ACF) in archived colon tissue from animals in a previous study was examined. The animals were fed a semisynthetic casein-based diet in which the carbohydrate pool was substituted with a dietary beet fiber (Fibeta) as the only source of fiber. Oral doses of dimethylhydrazine dihydrochloride (DMH-2HCl, 20 mg/kg body wt) once a week for 10 weeks were used as initiator. The rats were fed different levels of the fiber in a preinitiation period, during initiation, or in a postinitiation period. In general, the results showed a statistically significant inverse relation between duration of intake of high-fiber diet and number of animals with ACF, as well as the total number of ACF and number of small ACF (1-3 crypts) per affected animal. The previously reported data showed no protective effect of the dietary fiber at any stage of the colorectal carcinogenic process. The lack of correlation between the outcome of ACF and tumors could be related to the observation that statistically significant differences between groups were seen only in the total number of ACF and number of small ACF. The hypothesis that ACF are preneoplastic lesions needs to be supported by further experimental data. The present state of knowledge could indicate that ACF represent true preneoplastic lesions progressing into colon tumors or that ACF and colon tumors represent two parallel independent events as a consequence of the cancer initiation (i.e., the ACF not being preneoplastic lesions per se).
Transplants of NGF-Secreting Fibroblasts Restore Stimulus-Evoked Activity in Barrel Cortex of Basal-Forebrain-Lesioned Rats (2001)

Cholinergic nuclei in the basal forebrain supply the cerebral cortex with acetylcholine (ACh). Depletion of cholinergic fibers following basal forebrain lesion results in reduced stimulus-evoked functional activity in rat barrel cortex in response to whisker stimulation. We showed previously that exogenous delivery of nerve growth factor (NGF) to the lateral ventricle restores reduced functional activity toward normal despite persistent reductions in cortical cholinergic activity. Gene transfer of therapeutic peptides using genetically engineered cells allows for localized and biological delivery of compounds to the CNS, circumventing systemic administration or repetitive invasive surgery. In this study, we grafted genetically engineered fibroblasts that secrete NGF (NGF+) into three CNS loci of rats with unilateral basal forebrain lesions, along with control fibroblasts (NGF-) that did not secrete NGF. Only NGF+ fibroblasts grafted into ACh-depleted somatosensory cortex resulted in improvement of functional activity following cholinergic depletion. NGF+ fibroblast transplants into the lateral ventricle or basal forebrain did not improve functional activity nor did NGF- fibroblasts in any site. Similar to our previous experiments using intraventricular NGF injections, despite improvements in functional activity, the affected barrel cortex remained depleted of acetylcholinesterase-stained fibers following insertion of NGF+ fibroblasts. These data support the idea that NGF can act directly on the cerebral cortex following reductions in cholinergic innervation. The mechanism of NGF action is elusive, however, since the presence of its high-affinity receptor, trkA, in the cerebral cortex is controversial.
Inflammation‐Triggered Cancer Immunotherapy by Programmed Delivery of CpG and Anti‐PD1 Antibody (2016)

Inflammation-triggered combination delivery of anti-PD-1 antibody and CpG oligodeoxynucleotides (CpG ODNs) has been demonstrated to prevent cancer relapse utilizing postsurgical inflammatory response. The controlled release of anti-PD1 and CpG ODN by CpG DNA-based "nano-cocoons" can induce considerable immune response, which in turn significantly prolongs the survival time of mice.
[Ultraviolet A-I phototherapy for skin diseases]. (1999)

Favourable effects of sunlight on various skin diseases include inhibition of rapid proliferation of cells (psoriasis), modulation of cells in an inflammatory infiltrate (atopic eczema) and stimulation of proteolytic enzymes (scleroderma). The ultraviolet (UV) fraction of the solar spectrum is the most biologically active because it is almost completely absorbed by the skin. UVB and the combination of psoralens with UVA (PUVA) have become important therapeutic modalities, especially for psoriasis and eczema. Lamps producing long wave UV radiation are available: UVA-I light. Owing to its longer wavelength it penetrates more deeply into the skin and gives less risk of development of skin cancer than other forms of UV radiation. Good results are reported of application of UVA-I in patients suffering from atopic dermatitis, scleroderma, urticaria pigmentosa, and systemic lupus erythematosus.
