Better bounds for matchings in the streaming model (2013)

In this paper we present improved bounds for approximating maximum matchings in bipartite graphs in the streaming model. First, we consider the question of how well maximum matching can be approximated in a single pass over the input when O(n) space is allowed, where n is the number of vertices in the input graph. Two natural variants of this problem have been considered in the literature: (1) the edge arrival setting, where edges arrive in the stream and (2) the vertex arrival setting, where vertices on one side of the graph arrive in the stream together with all their incident edges. The latter setting has also been studied extensively in the context of on-line algorithms, where each arriving vertex has to either be matched irrevocably or discarded upon arrival. In the online setting, the celebrated algorithm of Karp-Vazirani-Vazirani achieves a 1--1/e approximation by crucially using randomization (and using O(n) space). Despite the fact that the streaming model is less restrictive in that the algorithm is not constrained to match vertices irrevocably upon arrival, the best known approximation in the streaming model with vertex arrivals and O(n) space is the same factor of 1--1/e.We show that no (possibly randomized) single pass streaming algorithm constrained to use O(n) space can achieve a better than 1--1/e approximation to maximum matching, even in the vertex arrival setting. This leads to the striking conclusion that no single pass streaming algorithm can get any advantage over online algorithms unless it uses significantly more than O(n) space. Additionally, our bound yields the best known impossibility result for approximating matchings in the edge arrival model (improving upon the bound of 2/3 proved by Goel at al[SODA'12]).Second, we consider the problem of approximating matchings in multiple passes in the vertex arrival setting. We show that a simple fractional load balancing approach achieves approximation ratio
High-Throughput Nuclear Magnetic Resonance Analysis Using a Multiple Coil Flow Probe (2003)

An automated method for high-throughput nuclear magnetic resonance (NMR) spectroscopy has been developed using a four-coil Multiplex NMR probe. The probe is constructed with solenoidal microcoils optimized for detection of small volume, mass-limited samples and a flow-through design. Four samples can be simultaneously injected into the Multiplex probe with a robotics liquid handler and then analyzed in rapid succession using a selective excitation experiment. Due to the simultaneous injection of four samples and the reduced analysis time with rapid selective excitation, the analysis rate achieved thus far is as low as 1 sample/34 s for 1D 1H NMR.
Pyroelectric properties of AlN (2000)

Pyroelectric properties of high-quality (0001)AlN films grown on (111) Si were studied. The pyroelectric coefficient p was measured using the dynamic method. The value was in the range of 6–8 μC/(m2 K), yielding a p/ε figure-of-merit of 0.8–0.95. The pyroelectric coefficient was independent of temperature and applied bias. Leakage current as low as 1–2×10−9 A/cm2 was measured at 5 V on large area devices. The obtained results indicate that AlN films can be used in pyroelectric thin-film devices.
The Effector Domain of Myristoylated Alanine-rich C Kinase Substrate Binds Strongly to Phosphatidylinositol 4,5-Bisphosphate (2001)

Both the myristoylated alanine-rich protein kinase C substrate protein (MARCKS) and a peptide corresponding to its basic effector domain, MARCKS-(151-175), inhibit phosphoinositide-specific phospholipase C (PLC)-catalyzed hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP(2)) in vesicles (Glaser, M., Wanaski, S., Buser, C. A., Boguslavsky, V., Rashidzada, W., Morris, A., Rebecchi, M., Scarlata, S. F., Runnels, L. W., Prestwich, G. D., Chen, J., Aderem, A., Ahn, J., and McLaughlin, S. (1996) J. Biol. Chem. 271, 26187-26193). We report here that adding 10-100 nm MARCKS-(151-175) to a subphase containing either PLC-delta or -beta inhibits hydrolysis of PIP(2) in a monolayer and that this inhibition is due to the strong binding of the peptide to PIP(2). Two direct binding measurements, based on centrifugation and fluorescence, show that approximately 10 nm PIP(2), in the form of vesicles containing 0.01%, 0.1%, or 1% PIP(2), binds 50% of MARCKS-(151-175). Both electrophoretic mobility measurements and competition experiments suggest that MARCKS-(151-175) forms an electroneutral complex with approximately 4 PIP(2). MARCKS-(151-175) binds equally well to PI(4,5)P(2) and PI(3,4)P(2). Local electrostatic interactions of PIP(2) with MARCKS-(151-175) contribute to the binding energy because increasing the salt concentration from 100 to 500 mm decreases the binding 100-fold. We hypothesize that the effector domain of MARCKS can bind a significant fraction of the PIP(2) in the plasma membrane, and release the bound PIP(2) upon interaction with Ca(2+)/calmodulin or phosphorylation by protein kinase C.
A 2003 update of bone physiology and Wolff's Law for clinicians. (2004)

By 1892, Julius Wolff and others realized that mechanical loads can affect bone architecture in living beings, but the mechanisms responsible for this effect were unknown, and it had no known clinical applications. In 2003 we know how this effect occurs and some of its applications. Our load-bearing bones (LBBs) include tibias, femurs, humeri, vertebrae, radii, mandibles, maxillae, wrists, hips, etc (so LBBs are not limited to weight-bearing ones). The strength of such bones and their trabeculae would represent their most important physiologic feature but in the special sense of relative to the size of the typical peak voluntary loads on them. The biologic "machinery" that determines whole-bone strength forms a tissue-level negative feedback system called the mechanostat. Two thresholds make a bone's strains determine its strength by switching on and off the biologic mechanisms that increase or decrease its strength. Equally, two thermostats can determine a room's temperature by switching on and off the room's heating and cooling systems. General features show that the largest voluntary loads on LBBs determine most of their strength after birth. These loads come from muscle forces so muscle strength strongly influences the strength of our LBBs. This process affects, in part, the healing of fractures, bone grafts, osteotomies, and arthrodeses; the bone's ability to endure load-bearing joint and dental endoprostheses; why healthy bones are stronger than the minimum needed to keep voluntary loads from breaking them suddenly or from fatigue; some general functions and disorders of bone modeling and basic multicellular unit-based bone remodeling; some limitations of in vitro data and of pharmaceutical actions; and the fact that many bone-active humoral and local agents have permissive roles in a bone's adaptations and healing, instead of forcing them to occur.
Corporate land, foreclosures, mortgage debt and land values in Iowa, 1939 (1939)

Between Jan. 1, 1937, and Jan. 1, 1939, ownership of farm land in Iowa by corporations increased from 11.2 to 11.9 percent of the farm area of the state. In this same period corporations deeded to individuals 558,000 acres but also acquired 791,000 acres, with a net increase of 233,000 acres. Not all the land in the name of corporations is available for sale, however, since approximately 20 percent of the total has been sold on contract, the title remaining with the corporation until a certain percentage of the purchase price is paid.\nOf the 4 million acres of farm land now owned by corporations, insurance companies with 2.7 million acres lead all other corporations in land holdings. Furthermore, the increase in acreage held by insurance companies during the last 2 years equals the net increase of all corporations.\nIn the 2-year period, 1937-1939, corporate ownership increased in western and southern Iowa but changed only slightly in the remainder of the state, with decreases more common than increases. The additions to corporate holdings in the western and southern areas were caused mainly by the continuation of drouth conditions in parts of these areas.

On the Geo-Indicativeness of Non-Georeferenced Text (2021)

Geographic location is a key component for information retrieval on the Web, recommendation systems in mobile computing and social networks, and place-based integration on the Linked Data cloud. Previous work has addressed how to estimate locations by named entity recognition, from images, and via structured data. In this paper, we estimate geographic regions from unstructured, non geo-referenced text by computing a probability distribution over the Earth's surface. Our methodology combines natural language processing, geostatistics, and a data-driven bottom-up semantics. We illustrate its potential for mapping geographic regions from non geo-referenced text.
The design of a CORBA group communication service (2002)

The common object request broker architecture (CORBA) is becoming a standard for distributed application middleware, and there are increasing needs for enriching the basic functionalities of CORBA. While mechanisms for persistence, transactions, event channels, etc. have been designed and specified for CORBA, no standard support is provided to handle object replication. In this paper we discuss the issue of augmenting CORBA with group communication, which is considered an adequate paradigm to handle replication. We distinguish two main approaches: the integration approach and the service approach. We argue that the service approach is more appropriate to CORBA as it preserves the modularity of the architecture. We describe a proposal for a group communication service and discuss some implementation issues.
A novel approach for ear recognition based on ICA and RBF network (2005)

Ear recognition is a new biometrics technique. Due to its unique physiological structure, position and stability, ear recognition is expected to be a promising authentication technique. In this paper, a hybrid system for classifying ear images is proposed. This system combines independent component analysis (ICA) and RBF network. The original ear image database is decomposed into linear combinations of several basic images. Then the corresponding coefficients of these combinations are fed up into RBF network instead of an original feature vector comprised of pixel values of grayscale images. The local features extraction of ICA and the adaptability of RBF neural network are combined reasonably. The robustness of the system is enhanced. The experiment results show that the recognition rate of ICA RBF method is improved substantially.
A New BaO‐TiO <sub>2</sub> Compound with Temperature‐Stable High Permittivity and Low Microwave Loss (1974)

The dielectric properties of ceramics in the TiO 2 ‐rich region of the BaO‐TiO 2 system were investigated. In the composition range between BaTi 4 O 9 and TiO 2 , another compound, Ba 2 Ti 9 O 20 , can be obtained when calcining and sintering conditions are controlled carefully. When dense and single‐phase, this ceramic has excellent dielectric and physical properties. At 4 GHz, the dielectric K = 39.8, Q = 8000, and τ K (temperature coefficient of dielectric constant) =−24 ± 2 ppm/°C.
COMPARATIVE STUDIES ON S-GLYCOPROTEINS PURIFIED FROM DIFFERENT <i>S</i>-GENOTYPES IN SELF-INCOMPATIBLE <i>BRASSICA</i> SPECIES I. PURIFICATION AND CHEMICAL PROPERTIES (1982)

S-glycoproteins, i.e. stigma glycoproteins that are heritable in correlation with S allele in self-incompatible Brassica species, were apparently purified for three S alleles in B. oleracea. From SDS gel electrophoresis, the estimated molecular weight for two of the S-glycoproteins was 57,000. The other S-glycoprotein was considered to be heterogeneous with molecular weights of 60,000 and 65,000. Distinct differences in amino acid content were found; in general, cysteine, methionine and histidine were low, and serine, glutamate, glycine, leucine, arginine and aspartate were high and variable between the S-glycoproteins. Differences in the isoelectric point were mainly attributed to the amino acid composition of each S-glycoprotein.
Validity of Fluctuation Theorem on Self-Propelling Particles (2011)

The experimental application of fluctuation theorem (FT) on nanometer to submicrometer sized systems has received thorough attention in the past several years. Nonetheless, the employment of FT on self-propelling objects has seldom been performed due to experimental difficulties. In this paper, we applied FT on a doublet that is comprised of asymmetrically coated self-propelling colloidal particles (Janus particles), which experiences a continuous rotation by applying AC electric field. We found that FT is valid for rotating self-propelling colloids by evaluating the estimated rotary torque to coincide with another form of torque estimation, which considers the rotation speed of the doublet and a simple Stokes equation.
LOS ANGELES DERMATOLOGICAL SOCIETY (1955)

<b>Pseudoatrophoderma Colli.</b>Presented byDr. Maximilian E. Obermayerand (by invitation) Dr. S.William Becker. Mrs. H. H., aged 45, of English-American stock, has had an asymptomatic scaling eruption of the neck, back, chest, arms, and mons veneris for 14 years, which varies in intensity but never completely disappears. It consists of partly diffuse, partly discrete lesions of wrinkled, atrophic appearance and whitish, at times buff, shade whose surfaces look glossy when viewed from certain angles. The patient had dyshidrosis of the hands and feet in 1954. Fungi could not be demonstrated on wet mounts or cultures. She also had urticaria from hypersensitivity to penicillin during that same year. Serologic test for syphilis was negative. Biopsy of skin above sternum showed a thinned epidermis with a fluffy, somewhat parakeratotic corneal layer, atrophy of some cells of the rete, and a dermis containing a minimal lymphocytic infiltrate in its
Protein kinase C activation by cis-fatty acid in the absence of Ca2+ and phospholipids. (1986)

Protein kinase C has been shown to be a phospholipid/Ca2+-dependent enzyme activated by diacylglycerol (Nishizuka, Y. (1984) Nature 308, 693-697; Nishizuka, Y. (1984) Science 225, 1365-1370). We have reported that unsaturated fatty acids (oleic acid and arachidonic acid) can activate protein kinase C independently of Ca2+ and phospholipid (Murakami, K., and Routtenberg, A. (1985) FEBS Lett. 192, 189-193). This study shows that other cis-fatty acids such as linoleic acid also fully activate protein kinase C in the same manner. None of the saturated fatty acids (C:4 to C:18) nor the detergents (sodium dodecyl sulfate and Triton X-100) tested here were as effective as oleic acid. Unlike oleic acid, these detergents strongly inhibited protein kinase C activity induced by Ca2+/phosphatidylserine (PS) and diacylglycerol. Lowering the critical micelle concentration of oleic acid by increasing ionic strength also strongly inhibited oleic acid activation of protein kinase C activity. Dioleoylphosphatidylserine activated protein kinase C effectively (Ka = 7.2 microM). On the other hand, dimyristoylphosphatidylserine, which contains saturated fatty acids at both acyl positions, failed to activate protein kinase C even in the presence of Ca2+. These observations suggest that: protein kinase C activation by free fatty acid is specific to the cis-form and is not due to their detergent-like action, cis-fatty acid activation is due to the direct interaction of protein kinase C with the monomeric form of cis-fatty acids and not with the micelles of fatty acids, and cis-fatty acids at acyl positions in PS are also important for Ca2+/PS activation of protein kinase C.

Treatment of Benign Prostatic Hypertrophy With Hydroxyprogesterone Caproate (1965)

Benign prostatic hypertrophy is a common disorder which produces clinical symptoms in 30% to 40% of males over 60 years old. Adequate surgical techniques are available for treatment of this disease. However, because the patients are usually elderly, there is frequently coincidental cardiac, renal, or pulmonary pathology adding to the risks of a surgical procedure. A medical therapy which could even delay the need for surgery would be useful. Medical prophylaxis capable of preventing this condition or of arresting its progress would be more useful. Numerous unsuccessful attempts at endocrine therapy for benign prostatic hypertrophy with estrogen or androgen, or both, have been made over the past 30 years. The rationale for such therapy has been based largely upon the hypothesis that altered secretion of testicular steroids occurs and is a factor in the production of benign prostatic hypertrophy. Despite the failure of such therapy in the past, there are
Clinical experience with the iLA Membrane Ventilator pumpless extracorporeal lung-assist device (2007)

Extracorporeal gas exchange by extracorporeal membrane oxygenation has been established clinically in patients with acute lung failure. The interventional lung-assist (iLA) Membrane Ventilator device (Novalung) is a sophisticated representative of a new generation of pumpless extracorporeal lung-assist devices that are driven by the patient's cardiac output and therefore, do not require extracorporeal pump assistance. The system is characterized by a new membrane gas exchange system with optimized blood flow that is integrated in an arteriovenous bypass established by vascular cannulation. This particular pumpless extracorporeal lung-assist device was applied in 1800 patients for artificial lung assistance with easy use and low cost. This article reviews the present state of clinical Novalung device implementation focusing on encountered limitations and conceivable future developments in the field.
<title>Position-sensitive scintillation neutron detectors using a crossed-fiber optic readout array</title> (1999)

The Spallation Neutron Source (SNS) under construction at the oak Ridge National Laboratory will be the most important new neutron scattering facility in the United States. Neutron scattering instruments for the SNS will require large area detectors with fast response (< 1 microsecond), high efficiency over a wide range of neutron energies (0.1 to 10 eV), and low gamma ray sensitivity. We are currently developing area neutron detectors based on a combination of <SUP>6</SUP>LiF/ZnS scintillator screens coupled to a wavelength- shifting fiber optic readout array. A 25 X 25-cm prototype detector is currently under development. Initial tests at the High Flux Isotope Reactor have demonstrated good imaging properties coupled with very low gamma ray sensitivity. In addition, we have developed a multi-layer scintillator/fiber detector to replace existing He-3 gas detector tubes for higher speed operation. This detector has demonstrated a neutron detection efficiency of over 75% at a neutron energy of 0.056 eV or about twice thermal. The response time of this detector is approximately 1 microsecond. Details of the design and test results of both detectors will be presented.
Relapse after allogeneic stem cell transplantation (2010)

Since allogeneic stem cell transplantation (SCT) represents an intensive curative treatment for high-risk malignancies, its failure to prevent relapse leaves few options for successful salvage treatment. While many patients have a high early mortality from relapse, some respond and have sustained remissions, and a minority has a second chance of cure with appropriate therapy. The prognosis for relapsed hematological malignancies after SCT depends on four factors: the time elapsed from SCT to relapse (with relapses occurring within 6 months having the worst prognosis), the disease type (with chronic leukemias and some lymphomas having a second possibility of cure with further treatment), the disease burden and site of relapse (with better treatment success if disease is treated early), and the conditions of the first transplant (with superior outcome for patients where there is an opportunity to increase either the alloimmune effect, the specificity of the antileukemia effect with targeted agents or the intensity of the conditioning in a second transplant). These features direct treatments toward either modified second transplants, chemotherapy, targeted antileukemia therapy, immunotherapy or palliative care.
Human Caliciviruses in Acute Gastroenteritis of Young Children in the Community (2000)

Episodes of acute gastroenteritis in prospectively followed children between 2 months and 2 years of age were examined for rotaviruses, enteric adenoviruses, astroviruses, and human caliciviruses, including both Norwalk-like viruses (NLVs) and Sapporo-like viruses (SLVs), using PCR and reverse transcription (RT)-PCR assays. A virus was identified in 60% (502/832) of all episodes and in 85% of the moderately severe or severe episodes. Human caliciviruses were as common as rotaviruses, both being detected in 29% of the cases. NLVs accounted for a 20% etiologic share of all cases; the clinical picture was a moderately severe disease with vomiting as a predominant symptom. SLVs were detected in 9% of the cases, the clinical picture being a mild diarrheal disease. Astroviruses were found in 10% and enteric adenoviruses in 6% of the cases. Diagnosis with PCR and RT-PCR methods increases the detection of all gastroenteritis viruses, particularly human caliciviruses. As a group, human caliciviruses are common causative agents of gastroenteritis in children <2 years of age in Finland, and, of these, NLVs cause more severe disease than SLVs.
Research of Optimization Algorithm for Path-Based Regression Testing Suit (2010)

A test suit need be reused in regressing test, which may contain repetitive and redundant test cases. To decrease the cost of maintaining the test suite and executing test cases in regression testing, according to selective regression testing, we select the test cases that can test part of changes, and then do the reduction for these selected test cases. Based on the requirements of static path coverage testing, this article proposed an algorithm for test suite optimization. According to the algorithm, we can find a change point with the minimum set of using cases for regression testing, and give application examples. The results show that, the algorithms can significantly reduce the size and the cost of the test suite for regression testing, and achieve good cost effectiveness.
