The University of Michigan Centimeter-Band All Stokes Blazar Monitoring Program: Single-Dish Polarimetry as a Probe of Parsec-Scale Magnetic Fields

The University of Michigan 26-m paraboloid was dedicated to obtaining linear polarization and total flux density observations of blazars from the mid-1960s until June 2012 providing an unprecedented record tracking centimeter-band variability over decades at 14.5, 8.0, and 4.8 GHz for both targeted objects and members of flux-limited samples. In the mid-1970s through the mid-1980s, and during the last decade of the program, observations were additionally obtained of circular polarization for a small sample of radio-bright (S>5Jy), active sources. Key program results include evidence supporting class-dependent differences in the magnetic field geometry of BL Lac and QSO jets, identification of linear polarization changes temporally associated with flux outbursts supporting a shock-in-jet scenario, and determination of the spectral evolution of the Stokes V amplitude and polarity for testing proposed models. Recent radiative transfer modeling during large flares supports a jet scenario with a kinetically-dominated, relativistic flow at parsec scales with embedded turbulent magnetic fields and dynamically-weak ordered components which may be helical; the circular polarization observations are consistent with linear-to-circular mode conversion within this turbulent jet environment.
A Novel Bioremediation Method for Shallow Layers of Soil Polluted by Pesticides

Excess amounts of pesticide have often been used to enhance the yield of agricultural products, and simultanously causing serious problems by polluting the soil and groundwater all over the world. For example, in the United States, large amounts of atrazine were used as a weed killer. The excessive atrazine sprayed by planes polluted rivers and soil near the farms, and this eventually was transferred to urban areas. The soil pollution in China is even more serious. Many agricultural fields and groundwater supplies are no longer used because of their contamination with pesticides and chemical fertilizers. An investigation by the FAO/ UNEP/WHO suggested that 1-5 million patients develop pesticide poisoning every year, and several thousand patients die [1].
ON THE ARTICULATORY BASES OF PROMINENCE IN ITALIAN

This study reports the first results of a research aimed to investigate how segmental variation is conditioned by prosody in Italian, by examining the acoustic and articulatory properties of syllables that are prominent at different levels of the prosodic hierarchy. We examined lip movement kinematics of unstressed, stressed and nuclearly accented syllables in order to understand the kinematic characteristics of accent-induced articulatory strenghthening. The kinematic results are then interpreted within a Task Dynamics model to evaluate how prosodically-driven variation can be accounted for by a particular dynamical parameter setting in a mass-spring gestural model.
Substrate integrated focused multibeam antenna based on the modified Rotman lens

In this paper, a modified substrate integrated waveguide (SIW) Rotman lens is proposed to feed several SIW slot array antennas in order to generate multiple focal points. This modified SIW Rotman lens, as a focused beamforming network (BFN), consists of eleven input beam ports and fifteen output array ports. Its phase shifting network is modified to satisfy the requirements of beam focusing and scanning. The focal point of the integrated multibeam antenna can be changed when it is excited at different input port.
A model based on rough sets for situation comprehension and projection

We present our results on the definition of a formal and interactive situation model improving comprehension of situations and supporting reasoning on projections of situations. The model is based on the rough sets and allows the creation of lattices that fuse the elements of an environment according to different perspectives and requirements of interest for a human operator. To support rapid decision making on dissimilarities between recognized and projected situations, we adopt some measures defined on the lattices. In many scenarios, like in emergency response, this can support the generation of early warnings that may help the human operators in identifying future dangerous events. An early evaluation has been accomplished by considering an illustrative case study based on real scenarios for management of vessel traffic.
Synchronous–Asynchronous Digital Voltage-Mode Control for DC–DC Converters

This paper investigates a mixed synchronous/asynchronous digital voltage-mode controller for DC-DC converters. In the proposed control architecture, the turn-on switching event is determined asynchronously by comparing the converter output voltage and a synchronously generated voltage ramp driven by the digital control using a low-resolution digital-to-analog converter. Switch turn-off is determined synchronously by the system clock. In the proposed approach, the derivative action of the proportional-integral-derivative voltage-mode controller is inherently obtained by the frequency modulation, without requiring the digital computation of the derivative action. A simplified small-signal model is also derived in order to analyze the performance achievable by the proposed solution. This control architecture features good dynamic performance, and frequency modulation during transients. Simulation and experimental results on a synchronous buck converter, where the digital control has been implemented in field programmable gate array, confirm the effectiveness of the proposed solution.
A 10b 100MS/s 25.2mW 0.18μm CMOS ADC with various circuit sharing techniques

This work describes a 10b 100MS/s 0. 18μm CMOS three-stage pipeline ADC. Two MDACs share an op-amp without MOS switches connected in series while removing a memory effect. Three flash ADCs use only one resistor ladder while the second and third flash ADCs share all pre-amps. The interpolation circuit employed in the flash ADCs halves the required number of pre-amps and an input-output isolated dynamic latch reduces the increased kickback noise caused by the pre-amp sharing. The prototype ADC with an active die area of 0.80mm2 shows DNL and INL within 0.58LSB and 0.94LSB, respectively, and consumes 25.2mW at 1.8V and 100MS/s.
Ablatio Placentae in Hypertensive and Normotensive Pregnants : Perinatal and Neonatal Outcomes

Objective: To compare the effect of abruptio placentae on the neonatal outcomes of hypertensive and normotensive pregnancies. Methods: 115 cases of placental abruption between January 2002 and February 2004 were reviewed in our study. These cases were grouped as normotensives (n=50) and hypertensives (n=65). The case groups were compared for demographic features, the degree of placental abruption, the type of delivery, intrauterine growth restriction, oligohydramnios, preterm delivery, intrauterine fetal demise, umbilical artery Doppler measurements, birth weight, gender, Apgar scores, necrotizing enterocolitis (NEC), respiratuar distress syndrome (RDS), sepsis, mechanical ventilation, intensive care unit admission (NICU), and neonatal mortality. Results: Incidence of placental abruption was determined as 0,26%. Grade 1 placental abruption was more frequent in the normotensive group while grade 2 abruption was more frequent among hypertensives (p<0.001; p<0.001). The rate of grade 3 placental abruption was not significantly different between the case groups (p=0.64). Intrauterine growth restriction and fetal distress were more frequent in the hypertensive case group (p<0.001, p<0.001 respectively). There was no significant difference between the case groups for either birth weight, oligohydramnios, preterm delivery, and stillbirth or the mode of delivery (p=0.26). Conclusion: Among pregnancies complicated with placental abruption, intrauterine growth restriction and fetal distress rate was significantly higher in the hypertensive group when compared with the normotensive group. There was no significant difference between hypertansive and normotensive pregnancies for other perinatal and neonatal parameters.
Answers in the Presence of Universal Constraints ?

The framework of consistent query answers and repairs has been introduced to alleviate the impact of inconsistent data on the answers to a query. A repair is a minimally different consistent instance and an answer is consistent if it is present in every repair. In this article we study the complexity of consistent query answers and repair checking in the presence of universal constraints. We propose an extended version of the conflict hypergraph which allows to capture all repairs w.r. t. a set of universal constraints. We show that repair checking is in PTIME for the class of full tuple-generating dependencies and denial constraints, and we present a polynomial repair algorithm. This algorithm is sound, i.e. always produces a repair, but also complete, i.e. every repair can be constructed. Next, we present a polynomial-time algorithm computing consistent answers to ground quantifier-free queries in the presence of denial constraints, join dependencies, and acyclic full-tuple generating dependencies. Finally, we show that extending the class of constraints leads to intractability. For arbitrary full tuple-generating dependencies consistent query answering becomes coNP-complete. For arbitrary universal constraints consistent query answering is Πp2-complete and repair checking coNPcomplete.
Inattentive Delirium vs. Disorganized Thinking: A New Axis to Subcategorize PACU Delirium

Background: Assessment of patients for delirium in the Post Anesthesia Care Unit (PACU) is confounded by the residual effects of the varied anesthetic and analgesic regimens employed during surgery and by the physiological consequences of surgery such as pain. Nevertheless, delirium diagnosed at this early stage has been associated with adverse clinical outcomes. The last decade has seen the emergence of the confusion assessment method-intensive care unit (CAM-ICU) score as a quick practical method of detecting delirium in clinical situations. Nonetheless, this tool has not been specifically designed for use in this immediate postoperative setting. Methods: Patients enrolled in a larger observational study were administered the CAM-ICU delirium screening tool 15 min after the latter of return of responsiveness to command or arrival in the post-anesthesia care unit. Numerical pain rating scores were also recorded. In addition, we reviewed additional behavioral observations suggestive of disordered thinking, such as hallucinations, a non-reactive eyes-open state, or an inability to state a pain score. Results: Two-hundred and twenty-nine patients underwent CAM-ICU testing in PACU. 33 patients (14%) were diagnosed with delirium according to CAM-ICU criteria; 25 of these were inattentive with low arousal, seven were inattentive with high arousal, and one was inattentive and calm and with disordered thinking. Using our extended criteria an additional eleven patients showed signs of disordered thinking. CAM-ICU delirium was associated with increased length of operation (p = 0.028), but a positive CAM-PACU designation was associated with both increased operation length and age (p = 0.003 and 0.010 respectively). Two of the CAM-ICU positive patients with inattention and high arousal reported high pain scores and were not classified as CAM-PACU positive. Conclusion: Disordered thinking is correlated with older patients and longer operations. The sensitivity of the existing CAM-ICU score in diagnosing delirium or disordered thinking in PACU patients is improved by the inclusion of a few extra criteria, namely: patients having perceptual hallucinations, in an unreactive eyes-open state, or who cannot state a pain score. We present this alternative screening tool for use in the post-anesthetic period, which we have named CAM-PACU.
Petty Envy When Assigning Objects THAYER MORRILL

Envy of another person’s assignment is “justified” if you “deserve” the object and it is possible to assign you to the object. Currently, the literature only considers whether or not the agent deserves the object and ignores whether or not assigning her to it is possible. This paper defines a fair set of assignments in terms of what is possible. We prove that a fair set of assignments has the same properties as the set of stable matches: the Lattice Theorem, Decomposition Lemma, and Rural Hospital Theorem all hold. Moreover, there is a unique, student-optimal fair assignment: the assignment made by Kesten’s Efficiency Adjusted Deferred Acceptance mechanism when all students consent. Consider the problem of assigning agents to objects. A key consideration is what constitutes a fair assignment. Typically, the literature calls an assignment unfair if there is a student i who desires an object a and has higher priority at a than a student j who is assigned to a.1 But what if it is impossible to assign i to a but it is possible to assign j to a? Ignoring for the moment why it might be possible for one student and not for another, if we honor i’s objection, it does not help i ∗North Carolina State University.

Please refer to that paper for a more complete discussion of the topic. I thank Antonio Romero-Medina for the many conversations and espressos. Both were very enjoyable and productive for this work. This was introduced by Balinski and Sonmez (1999) as the definition of a fair assignment. Following Abdulkadiroglu and Sonmez (2003), the literature typically refers to this as justified envy.
Submarine mass wasting and associated tsunami risk offshore western Thailand, Andaman Sea, Indian Ocean

Abstract. 2-D seismic data from the top and the western slope of Mergui Ridge in water depths between 300 and 2200 m off the Thai west coast have been investigated in order to identify mass transport deposits (MTDs) and evaluate the tsunamigenic potential of submarine landslides in this outer shelf area. Based on our newly collected data, 17 mass transport deposits have been identified. Minimum volumes of individual MTDs range between 0.3 km3 and 14 km3. Landslide deposits have been identified in three different settings: (i) stacked MTDs within disturbed and faulted basin sediments at the transition of the East Andaman Basin to the Mergui Ridge; (ii) MTDs within a pile of drift sediments at the basin-ridge transition; and (iii) MTDs near the edge of/on top of Mergui Ridge in relatively shallow water depths ( 1000 m) and/or comprise small volumes suggesting a small tsunami potential. Moreover, the recurrence rates of failure events seem to be low. Some MTDs with tsunami potential, however, have been identified on top of Mergui Ridge. Mass-wasting events that may occur in the future at similar locations may trigger tsunamis if they comprise sufficient volumes. Landslide tsunamis, emerging from slope failures in the working area and affecting western Thailand coastal areas therefore cannot be excluded, though the probability is very small compared to the probability of earthquake-triggered tsunamis, arising from the Sunda Trench.
Molecular Cytogenetics of some Anopheles Mosquitoes (Culicidae: Diptera)

Experimental work pertaining to the molecular cytogenetics of malaria vector species of mosquitoes by the application of PCR technique has been carried out. The main objectives of the study included the sequence characterization of nuclear rDNA internal transcribed spacers 1 and 2 (ITS1, ITS2) and mitochondrial DNA COII gene as potential molecular markers for studying genetic relatedness and phylogenetic kinship among six important species of genus Anopheles. The present studies involved the extraction of genomic DNA from a single female mosquito followed by its amplification with specific primers. The total length of each DNA band with respect to the number of nucleotides was calculated along with GC:AT content, ratio of substitutions due to transitions and transversions (ts/tv), insertions/ deletions and identification of tandem and nontandem repeat sequences. Out of the three studied molecular markers, ITS1 and ITS2 were GC rich while COII gene was AT rich. As for the incidence of insertions/deletions (indels) of bases is concerned, it was found maximum in ITS1 and ITS2 and minimum in conserved COII gene sequence . From the present results it was evident that except for An. culicifacies the ITS2 sequence of the remaining five species is under rapid evolutionary changes due to less conserved nature of the sequence. To the contrary ITS1 sequence was found to have highly variable length ranging from 300-900bp. It was found that An. stephensi + An. culicifacies and An. annularis + An. splendidus share a close genetic homology while An. subpictus and An. maculatus have hypervariable non-homologous genomic qualities. The phylogenetic dendrograms revealed that An. stephensi and An. culicifacies grouped together only when analysed by MP in case of ITS1 gene only while they drifted apart in case of ITS2 and COII gene. This is attributed to their host and habitat feeding preferences which have given them the dubious status of urban and rural vectors respectively.
Ultra low turn-on voltage and high-current InP DHBT with a pseudomorphic In0.37Ga0.63As0.89Sb0.11 base

We report on the dc and microwave characteristics of an InP/InGaAsSb/InGaAs double heterojunction bipolar transistor grown by solid-source molecular beam epitaxy. The pseudomorphic In<sub>0.37</sub>Ga<sub>0.63</sub>As<sub>0.89</sub>Sb<sub>0.11</sub> base reduces the conduction band offset (DeltaE<sub>C</sub>) at the emitter/base (E/B) junction and the base band gap, which leads to a very low VBE turn-on voltage of 0.35 V at 1 A/cm<sup>2</sup>. Current gain of 125 and peak f<sub>T</sub> of 238 GHz have been obtained on the devices with an emitter size of 1times10 mum<sup>2</sup>, suggesting that high current capability is achieved due to its type-II lineup at the InGaAsSb/InGaAs base/collector (B/C) junction.

In this study the extracted mean is give the help in detection of human sleep stage with the help of lab view software.
Dephasing in Metals by Two-Level Systems in the 2-Channel Kondo Regime

We point out a novel, non-universal contribution to the dephasing rate 1/\tau_\phi \equiv \gamma_\phi of conduction electrons in metallic systems: scattering off non-magnetic two-level systems (TLSs) having almost degenerate Kondo ground states. In the regime \Delta_{ren} < T < T_K (\Delta_{ren} = renormalized level splitting, T_K = Kondo temperature), such TLSs exhibit non-Fermi-liquid physics that can cause \gamma_\phi, which generally decreases with decreasing T, to seemingly saturate in a limited temperature range before vanishing for T \to 0. This could explain the saturation of dephasing recently observed in gold wires [Mohanty et al. Phys. Rev. Lett. 78, 3366 (1997)].
Falsification of Propensity Models by Statistical Tests and the Goodness-of-Fit Paradox

Gillies introduced a propensity interpretation of probability which is linked to experience by a falsifying rule for probability statements. The present paper argues that general statistical tests should qualify as falsification rules. The ‘goodness-of-fit paradox’ is introduced: the confirmation of a probability model by a test refutes the model's validity.An example is given in which an independence test introduces dependence. Several possibilities to interpret the paradox and to deal with it are discussed. It is concluded that the propensity interpretation properly reflects statistical practice, but it is not as objective as some adherents claim.
Proton Conduction in Grain-Boundary-Free Oxygen-Deficient BaFeO2.5+δ Thin Films

Reduction of the operating temperature to an intermediate temperature range between 350 °C and 600 °C is a necessity for Solid Oxide Fuel/Electrolysis Cells (SOFC/SOECs). In this respect the application of proton-conducting oxides has become a broad area of research. Materials that can conduct protons and electrons at the same time, to be used as electrode catalysts on the air electrode, are especially rare. In this article we report on the proton conduction in expitaxially grown BaFeO2.5+δ (BFO) thin films deposited by pulsed laser deposition on Nb:SrTiO3 substrates. By using Electrochemical Impedance Spectroscopy (EIS) measurements under different wet and dry atmospheres, the bulk proton conductivity of BFO (between 200 °C and 300 °C) could be estimated for the first time (3.6 × 10−6 S cm−1 at 300 °C). The influence of oxidizing measurement atmosphere and hydration revealed a strong dependence of the conductivity, most notably at temperatures above 300 °C, which is in good agreement with the hydration behavior of BaFeO2.5 reported previously.
A Fully Integrated Switched-Capacitor Regulator With Frequency Modulation Control in 28-nm FDSOI

The fully integrated switched capacitor voltage regulator comprises power cells distributed as a ring around the digital area to supply while the MIM capacitors are stacked above. Multiratio cells provide a wide output voltage range from 0.2 to 1.1 V with an input voltage of 1.8 V. A frequency modulation control loop is designed with proportional-integral control. Sampled-data modeling is used to derive the necessary transfer functions to build the control loop. A primarily test chip is fabricated in 28-nm FDSOI technology to evaluate the design. A power density of310 mW/mm2 is achieved at 72.5% peak efficiency with a silicon area overhead of 11.5%. Integrated
Taking the Charisma Out of Transformational Leadership

Transformational and cliarismatic leadership are critically assessed. A theoretical exploration of each reveals contradictions and research limitations for the two constructs. Charisma is defined in its origins as a social phenomenon and as a magical gift" possessed by leaders. Followers of cliarismatic leaders typically emulate or strongly identify with the leader. The transformational leader, in contrast, inspires followers to pursue organizational goals in lieu of self-interests. Followers oftransfonnational leaders are empowered to pursue organizational goals. The paper moves towards a reconsideration of transformational leadership, by not requiring charisma" and suggests that transformational leaders can operate and effectively transform " an organization using inspiration, intellectual stimulation, and individual consideration. Research implications are discussed.
