The use of hints in object-relational query optimization (2004)

There is a growing need to combine traditional relational data with new object feature into one integrated systems called as object-relational database management system (ORBMS) (Dorsey and Hudicka, 1999; Taniar, Rahayu and Srivastava, 2003). ORBMS is built based on SQL3 model, which consist object data types, row types, collection and abstract data types along with basic relational models (Carey, 1992; Stonebraker and Moore, 1996; Fuh et al., 1999; Taniar, Rahayu and Srivastava, 2003). The advantage of database applying SQL3 model is that the system is more flexible and massive scalability so that the immediate changes in the business process can be accommodated fast and easily (Fuh et al., 1999; Taniar, Rahayu and Srivastava, 2003). REF is one of essential data structures which have been introduced in Object-Relational Databases serves as a logical pointer to define the link between two tables (Taniar, Rahayu and Srivastava, 2003). This logical pointer has similar function to pointers in object oriented programming approach. There are three ways of writing REF join queries which are: REF Join, Path Expression Join, and DEREF/VALUE Join. REF Join is the most straightforward method to write Object-Relational queries where the REF data structure is used in the SQL statement to retrieve the REF value (not real data) stored in the ref attribute. Different with REF join, the final result of a Path expression join is the real data taken directly from the referred attribute. Finally, the DEREF/VALUE join method retrieves data from the actual object itself rather than from the table as the other two methods do (Loney and Koch, 2000; Oracle, 2002). Query optimization is the most important stage in query processing where the database optimizer has to choose a query-evaluation plan with minimized cost and maximized
A new digital implementation of quadrature-quadrature phase shift keying (1991)

Describes the digital algorithm implementation of a single DSP based 1.2 Kbits/sec Q/sup 2/PSK transmitter and receiver units. Further results have been obtained with this data bit rate. The algorithm has been implemented in a system based upon the TMS320C25 for the transmitter and upon the TMS320C30 for the receiver. Both, systems and algorithms are suitable for operation up to 9.6 Kbit/sec and more research is being carried out with this data bit rate. The designs of the digital filters, transmitter and receiver are expounded. >
Signal Transduction, Desensitization, and Recovery of Responses to Thyrotropin-Releasing Hormone after Inhibition of Receptor Internalization* (1998)

Three independent methods were used to block internalization of the TRH receptor: cells were infected with vaccinia virus encoding a dominant negative dynamin, incubated in hypertonic sucrose, or stably transfected with a receptor lacking the C-terminal tail. Internalization was blocked in all three paradigms as judged by microscopy using a fluorescently labeled TRH agonist and biochemically. The initial inositol trisphosphate (IP3) and Ca2+ responses to TRH were normal when internalization was inhibited. The IP3 increase was sustained rather than transient, however, in cells expressing the truncated TRH receptor, implying that the C-terminal tail of the receptor may be important for uncoupling from phospholipase C. After withdrawal of TRH, cells were refractory to TRH until both ligand dissociation and resensitization of the receptor had occurred. When surface-bound TRH was removed by a mild acid wash, which did not impair receptor function, neither wild-type nor truncated receptors were able to generate full IP3 responses for about 10 min. The rate of recovery was not altered by blocking internalization. Recovery of intracellular Ca2+ responses also depended on the rate of Ca2+ pool refilling. In summary, in the continued presence of TRH, phospholipase C activity declines quickly due to receptor uncoupling; this desensitization does not take place for the truncated receptor. After TRH is withdrawn, cells are refractory to TRH. Before cells can respond, TRH must dissociate and a resensitization step, which takes place on the plasma membrane and does not require the C-terminal tail of the receptor, must occur.
Reducing Conflicts in SMT VLIW Processor for Higher Throughput (2006)

Cache misses and insufficient instruction-level parallelism (ILP) in a single program make functional units of VLIW (very long instruction word) processor underused. Simultaneous multithreading (SMT) technology is one of the best choices to improve the utilization of functional units in processors, since it can convert thread-level parallelism (TLP) to ILP. Previous work investigate how to incorporate SMT technology with VLIW processors, but none of them reveals further what prevents SMT VLIW processors from achieving higher throughput. In addition, those methods that enhance throughputs for SMT superscalar processors are unsuitable for VLIW processors. In this paper, we propose an approach, which reduces conflicts among threads with moderate hardware costs, to improve the utilization of functional units. Experimental results show that our approach can effectively increase throughputs of SMT VLIW processors.
Assessment of Penile Blood Flow by Duplex Ultrasonography in 44 Men with Normal Erectile Potency in different Phases of Erection (1992)

Duplex ultrasonography is important in the diagnosis of vasculogenic erectile dysfunction. We measured the ultrasonographic parameters of cavernous blood flow in different phases of penile erection. We examined 44 volunteers with normal erectile potency. Doppler spectra of the cavernous artery were obtained in a time-dependent manner after intracavernous administration of papaverine. Following intracavernous pharmacological stimulation, the Doppler spectrum alters according to a specific pattern indicating the different hemodynamic phases of erection. Peak flow velocity and acceleration time, measured in the early post-injection phase, may be used to grade arterial inflow. The difference between resistance index in the pre-injection and late post-injection phases may be used to estimate veno-occlusive function. References values are defined.
A case report--The marked response to gemcitabine combined with irinotecan and low-dose cisplatin chemotherapy for advanced gastric cancer with multiple liver metastases. (2006)

A 69-year-old man with no sign of symptoms was admitted to our hospital for further examination and treatment of gastric cancer. Endoscopy revealed a Borrmann 3-type tumor in the cardia of the stomach. CT of the abdomen demonstrated a marked thickening of the stomach wall near the esophago-gastric junction, multiple liver metastases in bilateral liver lobes, and regional lymph node swelling around the cardia of the stomach. He consented and received systemic chemotherapy consisting of 0.5 h infusion of cisplatin (25 mg/body) followed by 0.5 h infusion of gemcitabine (800 mg/body) and 2.5 h infusion of irinotecan (60 mg/body) every 14 days as described below. Only the initial 1 course was administered with 5-FU (500 mg/body) as an inpatient, and further courses were performed as an outpatient with no severe adverse events. His tumors responded immediately to the chemotherapy, and restaging abdominal CT after 4-cycles of chemotherapy showed almost complete regression of liver metastases, and partial response to lymphadenopathy. The patient currently undergoes regular chemotherapy and remains in remission more than 6 months after the diagnosis of unresectable gastric cancer with liver metastases. It may be possible that the current chemotherapy will be neoadjuvant chemotherapy, and curative surgical resection can be performed.
The electrical properties of zinc selenide (1976)

The electrical conductivity and Hall coefficient of a variety of single crystals of zinc selenide have been measured. As-grown, undoped crystals have a resistivity ( approximately 1012 Omega cm) which is too large for successful Hall measurements to be made. However, after heat treatment at 850 degrees C in molten zinc, the resistivity of a sample is reduced to about 10-1 Omega cm. The samples are fairly heavily compensated. The Hall mobility of the free electrons is about 530 cm2 V-1 s-1 at room temperature when optical mode scattering is the dominant mobility-limiting mechanism. At lower temperatures, ionized impurity scattering becomes dominant. Crystals containing grown-in impurity donors such as indium, gallium and chlorine have also been investigated, as have crystals containing aluminium. Increasing the concentration of aluminium leads to overlap of the shallow donor wavefunctions with consequent impurity banding and the production of a degenerate semiconductor. Increasing the concentration of indium, gallium or chlorine is accompanied by anomalous behaviour.
Individual observer data for the 1955 Stiles–Burch 2° pilot investigation (1987)

Although the results of the 2 degrees Stiles-Burch investigation were published in 1955 in the form of mean data, individual results have not been available. It is only recently that they have been in wide demand. Since in 1955 this demand was not anticipated, individual results were left in an unprocessed form; the processing has now been completed. Tables are given for each of 10 observers and their mean for color-matching functions, unit (WDW) coordinates, and relative luminous efficiency functions.
Severe Fatigue and Depressive Symptoms in Lower-Income Urban Postpartum Women (2009)

The purpose of this study was to identify whether severe postpartum fatigue at 1 and 3 months postpartum was associated with depressive symptomatology at 6 months in lower-income urban women. A convenience sample of 43 lower-income postpartum women completed the Modified Fatigue Symptoms Checklist and Edinburgh Postpartum Depression scale at 1, 3, and 6 months postpartum. Participants who were severely fatigued at both 1 and 3 months postpartum were significantly more likely to exhibit depressive symptomatology at 6 months. Fatigue and depressive symptoms were moderately to strongly correlated at 1 (r = .68), 3 (r = .74), and 6 (r = .70) months postpartum (p = .001). Severe fatigue and depressive symptomatology often co-exist for months after childbirth. Future research should examine whether interventions to targeting severe postpartum fatigue in lower-income urban women may also effectively reduce depressive symptoms.

Toward the unification of three visual laws and two visual models in brightness perception (1989)

A novel visual model of brightness perception is introduced to resolve apparent incompatibilities among Fechner's logarithmic relation, Steven's power law response, and psychophysical and electrophysiological K/sub m/*I/(I+S) experimental results. The proposed visual model, which is based on combining and extending two existing ones (the multiplicative and photoreceptor visual models), is shown to predict these results successfully. Thus a unification of three apparently conflicting visual laws emerges, and the versatility and validity of the visual model are demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Principles of Radiobiology of Stereotactic Radiosurgery and Clinical Applications in the Central Nervous System (2012)

Stereotactic radiosurgery (SRS) has become an important treatment option for intracranial lesions and has recently been adapted to treat lesions outside the brain. Many studies have shown the effectiveness of SRS for the treatment of benign and metastatic tumors. Although DNA damage has been thought to be the principal form of radiation-induced damage, recent studies have shown that vascular endothelial damage is perhaps more important in the setting of high radiation doses per fraction such as those used in SRS. Furthermore, it has been shown that molecular responses to radiation differ based on dose per fraction. The principles of classical radiobiology are reviewed with explanation on why fractionation of radiotherapy allows optimization of the therapeutic ratio. The current understanding of the molecular responses that occur soon after the delivery of high radiation doses per fraction is also reviewed. A summary of current clinical evidence of radiation tolerance to SRS of brain, brainstem, optic chiasm and spinal cord is also provided. Recent advances in understanding the molecular basis of SRS response have uncovered a different biological response than previously thought. Further understanding of these molecular mechanisms will allow for the development of targeted radiosensitizers and radioprotectors to optimize the therapeutic ratio.
Role of atomic mass of underlayer material in the transition noise of longitudinal media (abstract) (1991)

Magnetic and recording properties of CoPtCr on Mo and W underlayers were investigated and compared to Cr underlayers over the sputtering pressure range of 3–24 mTorr. Normalized media transition noise decreases with increasing pressure in all cases, and the reduction can be attributed to a reduced intergrain exchange coupling due to isolation of the magnetic grains. In the low-pressure regime, the transition noise increases with increasing atomic mass of the underlayer, Cr&lt;Mo&lt;W. This trend can be attributed to the growth features of the underlayers which change from a partially coupled structure for Cr to closely coupled grains for W. We attribute this behavior in the low-pressure regime to increasing mobility with increasing atomic mass since the energy flux of the sputtered atoms and the back-reflected argon atoms increases with the atomic mass of the target. In the high-pressure regime, all underlayers produce an isolated grain morphology in the magnetic layer, which indicates sufficient thermalization of the atoms during the transport resulting in similarly low values of transition noise.
El uso y abuso de la contratación temporal del profesorado universitario: ¿Fin del “estado de excepción laboral” en las Universidades Públicas? A propósito de la sentencia del Tribunal Supremo de 1 de junio de 2017 (2017)

espanolEl peculiar regimen juridico de los profesores de universidad ha planteado una elevada litigiosidad en el seno de las universidades publicas. La mayor parte de estos litigios encuentran su origen en el caracter abusivo y/o fraudulento de las contrataciones temporales reiteradas y sucesivas de los profesores universitarios. En este contexto se incardina la STS de 1 de junio de 2017 en la que, por primera vez, el Tribunal Supremo aborda los limites a la contratacion temporal del profesorado universitario por parte de las universidades publicas y, en particular, al encadenamiento de diferentes contratos temporales especificos del ambito universitario para cubrir unas mismas funciones docentes durante un dilatado espacio de tiempo. EnglishThe specific legal regime for university lecturers has given rise to frequent litigation in public universities. The origin of the majority of these lawsuits is the abusive and/or fraudulent nature of the repeated and successive temporary recruitment of university lecturers. The Judgement of the Supreme Court of Justice of 1 June 2017 comes within this context. In it, for the first time, the Supreme Court of Justice addresses the limits to the temporary recruitment of university lecturers by public universities and, in particular, the linking of various temporary contracts specific to the university sphere to cover the same teaching duties over a long period of time.

Growth of hamsters during continual centrifugation (1962)

Female Syrian hamsters have been subjected to continual centrifugation for a period of 4 weeks at four or five times the earth's gravity. Animals were 5 weeks of age at the onset of exposures. Although an increased gravitational field curtails body growth, certain organs were found to show an increase in their relative mass when compared to control littermates. The heart, diaphragm, gastrocnemius muscle, lungs, kidney, and head showed a relative increase in mass, and the femur bones of centrifuged hamsters showed a relative increase in length.
Metal Ion Chelates of Lipophilic Alkyl Diazinyl Ketoximes as Hydrolytic Catalysts (1999)

A series of lipophilic dodecyl hetaryl ketoximes (hetaryl = pyridin-2-yl, pyridazin-3-yl, pyrimidin-2-yl, pyrimidin-4-yl, pyrazin-2-yl as well as their methyl hetaryl homologues was synthesized and hydrolytic activity of their chelates with Co 2+ , Ni 2+ , Cu 2+ and Zn 2+ in a micellar matrix of hexadecyltrimethylammonium bromide or in homogeneous aqueous solutions was investigated using 4-nitrophenyl acetate, 4-nitrophenyl hexanoate and 4-nitrophenyl diphenyl phosphate as model substrates. While Co 2+ and Cu 2+ chelates are almost inactive, those of Ni 2+ and Zn 2+ exhibit considerable activity. None of the studied chelates promotes hydrolysis of the used phosphate. The effective species are chelates of the metal : ligand stoichiometry 1 : 3 and 1 : 1 with Ni 2+ and Zn 2+ , respectively, when the ester cleavage proceeds in the micellar matrix. The 1 : 2 stoichiometry was found in aqueous solutions of Ni 2+ and Zn 2+ chelates of methyl ketoximes.
Incidence of subarachnoid haemorrhage: a systematic review with emphasis on region, age, gender and time trends (2007)

The overall incidence of SAH is approximately 9 per 100,000 person-years. Rates are higher in Japan and Finland and increase with age. The preponderance of women starts only in the sixth decade. The decline in incidence of SAH over the past 45 years is relatively moderate compared with that for stroke in general.
Face liveness detection (2016)

Biometric system is widely used to recognize the authorized person based on either behavioral characteristics or physical. But this can be spoofed using various traits. Spoofing attack is nothing but attacking or harming biometric recognition system using security features to use system without permission of authorized user. These biometric systems can be easily attacked by spoofs like peoples face images, masks and videos which are easily available from social media. In the proposed work, method is discuss to detect the spoofing attack. Spoofing methods like photo, mask or video image can be easily recognized by this method. This method depends on illumination and some other characteristics of face which are used to detect spoofed face. The goal of this work is to develop a efficient protection method against these types of attacks. By last, proposed work efficiently detects the live face using illumination characteristics in MATLAB tool.
Fundamental Difference of Power Handling Between CE and CB HBTs (2006)

Fundamental power handling of common-emitter (CE) and common-base (CB) (SiGe) power HBTs is compared by measuring their dynamic load lines under large-signal operation with input and output matched for maximum output power (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> ). The distinct difference of load lines indicates the fundamental different power amplification mechanisms between the two configurations. It is shown that under voltage-source bias the CE configuration always provides higher (saturated) output power (P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">out</sub> ) than the CB configuration, while higher power gain and power added efficiency (PAE) could be obtained from the CB configuration than the CE configuration before entering the power saturation region
<title>Real-time evaluation techniques for real-time image processing hardware</title> (1992)

Real-time hardware developed for image processing applications such as image enhancement, segmentation, image registration, pattern recognition, etc. can not be thoroughly debugged and analyzed for its performance by using conventional test equipment. To cite an example, the hardware for image registration may be failing intermittently or the registration point may be drifting even when the scene and the sensor are static. There is no way of knowing whether the malfunction is due to input data or any noise glitches. Therefore, for evaluating real-time image processing hardware, it is necessary to acquire image sequence data in real-time and also capture the status of the tracker in real-time. Test equipment like logic analyzer, microprocessor development systems do not have the capability to acquire and store image sequences. General purpose data acquisition systems on the IBM PC compatible computer are not suitable as the data rate required is about 500 kbytes/sec. the design of an interface card for achieving this data rate using IEEE-488 (GPIB) interface is described. Results on the evaluation of image processing hardware using this card are also presented.
Sample Examination Manual (1981)

First published in 1981, this book was selected to provide the oil industry with a Standard Lithologic Logging System for use in describing cuttings samples from a drilling operation. Roger Swanson developed this manual over years of teaching in the Shell Training Program at Houston. This five-part handbook is the standard for examining and describing samples. Sections include general examination procedures, equipment and techniques, standard abbreviations, comparator charts and graphs, and standard legends and classifications
On the Nearest Neighbor of the Nearest Neighbor in Multidimensional Continuous and Quantized Space (2008)

The probability that an entity in a set of entities uniformly distributed in space is the nearest neighbor of its nearest neighbor is evaluated for generic distances in a multidimensional environment. Such an expression is then specialized for systems with norm-based distances and for systems with quantized norm- based distance. Examples for scalar products and sup-norm are derived. When applicable, invariances with respect to the underlying distance and entities density are highlighted. Dimensionality effects are investigated.
Assessment of slope stability at Poro-o-tarao tunnel south portal (1974)

Poro-o-tarao tunnel is located on the North Island Main Trunk Railway 32 km south of Te Kuiti. The tunnel penetrates a ridge which forms the watershed between the headwaters of the Mokau and Wanganui Rivers.
