Looking Forward: Meeting the Global Need for Leaders Through Guided Mindfulness

In a changing global workplace, emerging leaders must develop skills that extend beyond those of directing others. Global leaders must be skilled motivators, engagers, and adapters to successfully lead across cultures and contexts. The urgent global demand for these critical skills necessitates moving beyond current developmental practices. This chapter first reviews the strengths and weaknesses of traditional approaches to leadership development (workshops, coaching, action learning, stretch assignments, and blended approaches). Guided Mindfulness, a flexible and dynamic model of leadership development, is then presented as a new approach to preparing emerging global leaders. Guided Mindfulness builds on experience-based learning that the traditional approaches recommend; however, the added component of guided reflection ensures that new knowledge is consolidated and internalized. This chapter concludes with a discussion of the potential benefits and gains of the Guided Mindfulness approach.
A technoeconomic analysis of perovskite solar module manufacturing with low-cost materials and techniques

After rapid progress in the past few years, emerging solar cells based on metal halide perovskites have become a potential candidate to rival and even outperform crystalline silicon photovoltaics (PV) in the marketplace. With high material utilization, easy manufacturing processes, and high power conversion efficiencies >20%, many experts anticipate that perovskite solar cells (PSCs) will be one of the cheapest PV technologies in the future. Here we evaluate the economic potential of PSCs by developing a bottom-up cost model for perovskite PV modules fabricated using feasible low-cost materials and processes. We calculate the direct manufacturing cost ($31.7 per m2) and the minimum sustainable price (MSP, $0.41 per Wp) for a standard perovskite module manufactured in the United States. Such modules, operating at 16% photoconversion efficiency in a 30-year, unsubsidized, utility-level power plant, would produce electricity at levelized cost of energy (LCOE) values ranging from 4.93 to 7.90 ¢ per kW per h. We discuss limitations in comparing calculated MSPs to actual market prices, determine the effect of module lifetime, examine the effects of alternative materials and constructions, and indicate avenues to further reduce the MSP and LCOE values. The analysis shows that PSCs can emerge as a cost leader in PV power generation if critical remaining issues can be resolved.
Characterization of metallothionein-like protein in rat brain.

A metallothionein-like protein has been identified recently in the rat brain which resembles in some but not all aspects a hepatic metallothionein. The synthesis of this protein is stimulated following the administration of zinc and copper but not cadmium. The zinc-stimulated protein incorporates 35s cysteine 24-fold higher than the native, unstimulated protein; is blocked by actinomycin D; produces two isoforms by ion exchange chromatography on DEAE Sephadex A 25 columns; and, by high performance liquid chromatography, depicts a similar but not identical profile to zinc-stimulated hepatic metallothionein. Preliminary studies have shown that the metallothionein-like protein isoform I possesses a Mr of 6200 and consists of 60 residues with 12 cysteine and no histidine, arginine, leucine, tyrosine, or phenylalanine. Since the synthesis of this protein is reduced in the brains of zinc-deficient rats, it is postulated that the free pool of zinc may serve as one of the factors that regulates the synthesis of this protein.
A new insight into asphaltenes aggregation onset at molecular level in crude oil (an MD simulation study)

Abstract The findings reported here is to understand the nature of asphaltenes aggregation behavior at the molecular level in crude oil. Previous studies have been rich with the statistical and macroscopic aspects of heavy organics behavior in petroleum fluids. Molecular dynamics simulations of three different model asphaltene molecules in a "modeled crude oil" composed of n-heptane and o-xylene were conducted. The roles of van der Waals (vdW), hydrogen bond (H-b), and electrostatic (ES) interaction energies on asphaltenes aggregation were investigated. Trends in aggregations, radial distribution functions (RDFs), vdW, H-b, and ES interactions were produced and analyzed. Our studies indicated asphaltenes with different molecular structures behaved differently from one another. At high paraffinic conditions, the preferred stacking of asphaltene molecules was face-to-face. The presence of H-b enhanced the stability of the aggregate. The number of H-bs varied in each model of asphaltene, depending on their detailed structures. The ES interactions between asphaltenes were either attraction or repulsion depending on the molecular structure. Overall, the major factor was the architecture of each asphaltene molecule, such as the number and length of chains, the number and position of heteroatoms, and the number and size of the aromatic cores where they are linked together to represent asphaltene behavior.
Abstract 14799: In-vitro Contractile and Echocardiographic Right Ventricular Function in Patients with Tricuspid Regurgitation

Objective: Right ventricular (RV) dysfunction is often cited as a reason not to intervene in patients with tricuspid regurgitation (TR). We compared quantitative echocardiographic measures of preoperative RV function, and in vitro function of RV muscle harvested during cardiac surgery between mild and severe TR patients. Methods: 43 cardiac surgical patients (19 with TR grade 3+/4+ and 24 with grade 0/1+/2+) underwent trabecular harvest from RV free wall through a right atriotomy during valve repair or replacement. Preoperative echocardiographic RV measurements-- tricuspid anular plane systolic excursion (TAPSE), myocardial performance index (MPI), speckle-derived global longitudinal systolic strain (Strain) and strain rate (SR)--were correlated with isometric contraction of 2 muscle trabeculae, 1-2 mm thick 8-10 mm long. At length of maximal tension development, we measured resting tension, developed tension, and developed tension after isoproterenol administration. Results: Correlations were found among echocardiographic measures of RV function: TAPSE with Strain (r= -0.65) (left Fig.), MPI with Strain (r= 0.48), TAPSE with SR (r= -0.47). No strong correlations were seen between isometric contractile variables and these echocardiographic measures. No significant differences in in-vitro muscle contractile function were seen between 0/1+/2+ and 3+/4+ TR patients (right Fig.). Conclusions: TAPSE, MPI and deformation parameters are correlated with each other but not with contractile function of RV muscle in vitro . The preservation of trabecular function in patients with 3+/4+ TR suggests recovery may be possible with normalization of loading conditions. Impairment of noninvasive systolic parameters in TR does not signify irreversible RV dysfunction.

Statistical Designs from Room’s Squares with Applications

Combinatorial properties of various experimental designs derived from Room’s squares, relevant to statistical analysis of data from such designs have been examined. It is noticed in particular that a balanced Room’s square provides us with a doubly balanced design which can be used to estimate residual effects of treatments in a sequence of experiments using the same experimental units. It is shown how incomplete paired-comparison designs with a certain degree of symmetry can be derived from Room’s squares. Different approaches to analysis of data from paired-comparison designs for the purpose of establishing an order or partial order among the objects compared are examined. In particular it is noted that ‘Multidimensional Scaling techniques’ can be used on the dissimilarities between pairs of objects ascertained from paired-comparison designs to establish an order or partial order between the objects.
(Science) Fiction: Genre Hybridization in Jacques-Yves Cousteau and Louis Malle's The Silent World (1956)

ABSTRACT:Upon its release, The Silent World (1956) immediately changed the way the ocean was popularly represented. While revolutionary in its presentation, the film draws heavily from the vocabularies of two established yet disparate genres—safari and science fiction. This hybridization is explored by examining both the film's text and context.
Prolymphocytic transformation of lymphoplasmacytic lymphoma: an extremely unusual event

Although rare cases of prolymphocytic transformation from splenic B-cell lymphomas and follicular lymphoma have been reported, prolymphocytic transformation from lymphoplasmacytic lymphoma has not been previously reported. We report a case of 76-year-old-male patient with a history of Waldenstrom macroglobulinemia diagnosed in 2010 and treated with infusion chemotherapy. He was in clinical remission for 5 years. In 2016, he presented with diffuse lymphadenopathy, and a head and neck lymph node biopsy showed lymphoplasmacytic lymphoma. MYD88 mutation was detected by polymerase chain reaction. A subsequent bone marrow biopsy showed B-cell lymphoma with increased prolymphocytes. Peripheral blood showed numerous circulating prolymphocytes. MYD88 was detected by polymerase chain reaction in the bone marrow. Cerebrospinal fluid was positive for lymphoma cells with prolymphocytic morphology. An IgM κ paraprotein was noted by immunofixation performed on the patient's serum, urine, and cerebrospinal fluid. The patient was resistant to chemotherapy, developed multiorgan failure, and died shortly thereafter.

Distance matters

Giant strides in information technology at the turn of the century may have unleashed unreachable goals. With the invention of groupware, people expect to communicate easily with each other and accomplish difficult work even though they are remotely located or rarely overlap in time. Major corporations launch global teams, expecting that technology will make "virtual collocation" possible. Federal research money encourages global science through the establishment of "collaboratories." We review over 10 years of field and laboratory investigations of collocated and noncollocated synchronous group collaborations. In particular, we compare collocated work with remote work as it is possible today and comment on the promise of remote work tomorrow. We focus on the sociotechnical conditions required for effective distance work and bring together the results with four key concepts: common ground, coupling of work, collaboration readiness, and collaboration technology readiness. Groups with high common ground and loosely coupled work, with readiness both for collaboration and collaboration technology, have a chance at succeeding with remote work. Deviations from each of these create strain on the relationships among teammates and require changes in the work or processes of collaboration to succeed. Often they do not succeed because distance still matters.
Synthesis and characterization of a hydro tris(3-phenylpyrazolyl)borato nickel(II) semiquinonate adduct

Abstract The in situ oxidation of 3,5-di-tert-butylcatecholate (3,5-DBC) by ambient O2 in the presence of nickel(II) tetrafluoroborate and sodium hydrotris-(3-phenylpyrazol-1-yl)borate (Na[TpPh]) results in the formation of a square pyramidal NiII complex bearing a κ3-[TpPh]− and a bidentate, 3,5-di-tert-butylsemiquinonate ligand radical ([3,5-DBSQ] − characterized by X-ray crystallography, NMR spectroscopy and cyclic voltammetry (CV), which all support the presence of a bound semiquinonate ligand. Density-functional-theory (DFT) was used to calculate the electronic and magnetic structure of [TpPh]Ni(3,5-DBSQ) predicting strong, antiferromagnetic coupling (J = −364 cm−1) between the high-spin NiII center and the [3,5-DBSQ]− radical consistent with the room-temperature magnetic moment of 2.4 μB determined by 1H NMR. Time-dependent DFT (TD-DFT) enables assignment of the experimental absorption spectrum and suggest electronic communication between the [TpPh]− and (3,5-DBSQ)− ligands.

Key Transitions in Morphological Development Improve Age Estimates in White Sturgeon Acipenser Transmontanus

We reared white sturgeon Acipenser transmontanus under laboratory conditions and found that a random-forest model containing scute counts and total length predicted age significantly better than total length alone. Scute counts are rapid, inexpensive and non-lethal meristics to gather in the field. This technique could improve age estimates of imperilled sturgeon populations.
New records of Dicrepidius ramicornis (Coleoptera: Elateridae: Elaterinae) from Dominican Republic, Hispaniola

Dicrepidius ramicornis (Palisot de Beauvois, 1805) is an elaterid beetle widely distributed in the Americas. Although first recorded from “Saint-Domingue” by Chevrolat in 1867, its presence in Hispaniola has been subsequently overlooked. In this note, I provide the first data-backed records for this species from the Dominican Republic and the first from Hispaniola since then.
Differential impact on speech production from chronic thalamic DBS in Essential Tremor and that from STN DBS in Parkinson's disease

Essential Tremor (ET) is the most common tremor syndrome seen in adults. The characteristic tremor in ET is postural and action tremors, with a frequency of 4–7 Hz; while in patients with Parkinson’s disease (PD), the dominant tremor is resting tremor with a typical frequency of 5 Hz. Deep brain stimulation (DBS) in the ventral intermediate nuclei (Vim) has been shown effective in treating action or intention tremors in medically resistant ET, while DBS in the subthalamic nucleus (STN) has been shown effective in treating rigidity, rest tremor and Dopa-induced dyskinesias in PD. However, chronic bilateral DBS, whether in Vim or STN, may have negative impact on speech production. We report two cases where both patients received DBS greater than one year and developed speech impairment. When the stimulation in Vim was turned off for 30 min in ET, the patient's speech returned to the baseline while turning the STN stimulation off for 30 min in PD, minimal changes were observed and 12 h with stimulation-off were required for speech to return to the non-stimulated state.Essential Tremor (ET) is the most common tremor syndrome seen in adults.

Current and potential methods for second trimester abortion.

Abstract Medical and surgical methods can both be recommended for second trimester abortion (after 12-weeks of gestational age). Induced abortion with a mifepristone and misoprostol regimen is the preferred approach; where mifepristone is not available, misoprostol alone for medical abortion is also effective. Dilation and evacuation (D&E) is the procedure of choice for surgical abortions, and adequate cervical preparation contributes significantly to safety. Availability of drugs and instruments, ability to provide pain control, provider skill and comfort, client preference, cultural considerations, and local legislation all influence the method of abortion likely to be performed in a given setting. Both surgical and modern medical methods are safe and effective when provided by a trained, experienced provider.
High-performance silicon imagers, back illumination using delta and superlattice doping, and their applications in astrophysics, medicine, and other fields

Abstract Since the advent of digital imaging in 1969, many inventions and much progress have been made to produce high-performance silicon imagers with ultrahigh resolution, large format, low noise, and high sensitivity. Discoveries about the birth and evolution of our universe, detection of extrasolar planets, and new windows into our solar system and the universe have been made possible using high-performance silicon imagers in Earth-orbiting telescopes such as the Hubble, Galaxy Evolution Explorer (GALEX), and Kepler Space Telescopes. In addition, instruments in missions visiting or orbiting our solar system planets such as Cassini (mission to Saturn), Galileo (mission to Jupiter), Mars Exploration Rover (MER), and Mars Science Laboratory (MSL) have demonstrated the power of this imaging technology. Discoveries made possible by these missions, in turn, have created new challenges and have placed more demands on the next generation of detector and imaging arrays in order to facilitate further discoveries. In this chapter, we discuss principles of operation in solid-state imaging followed by a short description of various electronic readout schemes and structures used today in imaging devices. We then focus on scientific imagers, including photon counting detectors and the role of back illumination in the design of high-performance silicon imagers, in particular focusing on delta and superlattice doping of back-illuminated detectors. We briefly discuss applications in astronomy and planetary science, ending with a brief note on biomedical and machine vision applications.

Assessing Anomaly-Based Intrusion Detection Configurations for Industrial Control Systems

To reduce cost and ease maintenance, industrial control systems (ICS) have adopted Ethernetbased interconnections that integrate operational technology (OT) systems with information technology (IT) networks. This integration has made these critical systems vulnerable to attack. Security solutions tailored to ICS environments are an active area of research. Anomalybased network intrusion detection systems are well-suited for these environments. Often these systems must be optimized for their specific environment. In prior work, we introduced a method for assessing the impact of various anomaly-based network IDS settings on security. This paper reviews the experimental outcomes when we applied our method to a full-scale ICS test bed using actual attacks. Our method provides new and valuable data to operators enabling more informed decisions about IDS configurations.
Left Ventricular Chamber Shape During Vena Caval Occlusion: Improved MRI-based Measurement of the End-Systolic Pressure-Volume Relationship in Normal Sheep

Abstract The left ventricular (LV) end-systolic pressure volume relationship (ES; ESPVR) is the cornerstone of systolic LV function analysis. Recently, it became possible to measure 2D LV chamber shape during vena cava occlusion (VCO) with MRI. We used an improved level-set semi-automatic segmentation method (LSSM) to determine the effect of VCO on LV geometry, ES pressure area (PA) and ESPVR. 10 healthy adult sheep were anesthetized. LV pressure transducer and inferior vena cava (IVC) balloon catheter were percutaneously inserted. Ferumoxytol (0.125 ml/kg iv; AMAG Pharmaceuticals, Waltham, MA) was given to enhance blood pool contrast. LV pressure and 2D retrospectively-gated cine MRI of LV cross sections 25 (Apex), 50 (Mid) and 75% (Base) of the distance from the apex to the base of the LV were obtained during separate IVC balloon inflations (VCO). LV pressure was digitally filtered and LV chamber segmented with the LSSM. Cross sectional area, major and minor axes, major axis orientation, ESPAR and ESPVR were calculated. The LSSM had excellent reliability. All cross sections became more elliptical during VCO. The orientation (angle) of each major axis relative to the anterior RV insertion shifted during VCO. However, the orientation remained toward the septum. There was chamber collapse (LV area In conclusion, MRI-based measurement of LV geometry, ESPAR and ESPVR during VCO is a valuable method that may lead to improved understanding of systolic LV function. New and Noteworthy Real-time MRI was used to continuously measure the LV PA relationship as loading conditions were transiently varied in anesthetized sheep. All three examined cross-sections became more elliptical during VCO. The ESPAR were non-linear at all three cross-sections. Chamber collapse at the apical level during VCO resulted in a non-linear ESPVR. The heart contracted in a non-concentric manner during VCO which could inform modeling studies and elucidate mechanisms underlying LV adaptations to sudden load changes.
Evaluation of the Communication Motif for a Distributed Eigensolver using the SST Network Simulation Tool

A new motif that corresponds to the communication operations of the distributed LOBPCG eigensolver used in the Many-Fermion Dynamics-nuclear, or MFDn, code is constructed. The impact of communication strategy and process placement are evaluated on current and future architectures using the SST network simulation tool. Simulation of the communication motif is validated against production runs on the Cori system at NERSC. We identify the strengths and shortcomings of SST in doing so.

Utility of mutational analysis for risk stratification of indeterminate thyroid nodules in a real-world setting.

OBJECTIVE American Thyroid Association (ATAn) 2015 guidelines recommend repeat fine-needle aspiration with molecular marker profiling (MMP) or diagnostic lobectomy in thyroid nodules yielding atypia of unknown significance/follicular lesion of unknown significance (AUS/FLUS) or follicular neoplasm/suspicious for follicular neoplasm (FN/SFN) cytology. Our objective is to describe the molecular profiles and histological correlates of these cytologically indeterminate nodules (CIN) to aid risk stratification. DESIGN Retrospective chart review. PATIENTS Adults with CIN that underwent MMP from 2017 to 2020. MEASUREMENTS Pearsons' χ2 , Fisher's exact test, nonparametric testing and multiple regression analysis were performed. RESULTS A total of 89 CIN underwent mutational analysis. Of 55% (n = 49) were Bethesda class III AUS/FLUS and 45% (n = 40) were Bethesda class IV FN/SFN. The US phenotype of a CIN was isoechoic (53%) or hypoechoic (32%) with well-defined margins (98%), absence of calcifications (75%) and mildly increased internal vascularity (70%). A total of 84% and 87% of nodules were classified as mild/moderate or low/intermediate risk per the Thyroid Imaging Reporting and Data System and ATA classifications, respectively. Based on the Thyroseq patient management resource, 6.7% (n = 6) of nodules had a high predicted probability of cancer (≥95%), 41.6% (n = 37) were intermediate probability (40%-94%) and 51.7% (n = 46) were low probability (<40%). MMP revealed positive mutations in 45% (n = 40) of nodules, with 71% demonstrating RAS mutations. Of the nodules that underwent resection (n = 38), 39% (n = 15) had malignant pathology. Increasing the threshold to recommend surgical resection to a Thyroseq predicted probability of cancer to ≥50%, had a 100% sensitivity and 65% specificity for detecting malignant nodules (area under the ROC curve: 0.86). The positive predictive value was 37% and the negative predictive value was 100%. CONCLUSION US phenotypes of CIN nodules were variable and did not aid in differentiating malignant from benign nodules. Of the CIN nodules with a positive MMP, most were RAS and had a benign pathology. With the exception of high-risk genetic markers for malignancy, the threshold to recommend surgical resection should be raised for CIN. Further studies to improve risk stratification in these nodules are required.

AIRFIELD PAVEMENT EVALUATION-FAA VIEWPOINT

The FAA is currently revising the theory and design procedures utilized for the structural design and evaluation of airport pavements. The new pavement design methodology employs several recommended changes to the theory under which previous design curves were based, i.e.: (1) Use of measured rather than assumed soil strength in flexible pavement design; (2)assumption of jointed edge loading of slabs instead of interior slab loading in rigid pavement design; and (3)employment of nondestructive testing techniques (in conjunction with destructive tests) to evaluate load carrying capacity of pavements and in the design of pavement overlays. The net result in the new methodology will be a slight increase in runway pavement thickness requirements.
Measurement and evaluation of pitting corrosion

Pitting is a destructive form of localized corrosion that requires careful analysis and evaluation. Metal surfaces are examined first to identify and determine the extent of pitting, which may be described in terms of standard charts. Nondestructive tests may be used, but they have limitations. Pit depths provide more meaningful information and can be determined by microscopic measurement, depth gages, and other techniques. Statistical methods can be used to show the probability of pitting to estimate maximum pit depths or to show the relationship with time. The change in mechanical properties may also provide useful information.
White matter abnormalities as a marker of Parkinson’s disease cognitive impairment: a diffusion tensor imaging study (P3.017)

Objective: To investigate markers of white matter (WM) microstructural integrity across the Parkinson’s disease (PD) cognitive spectrum using diffusion tensor imaging (DTI) measures of fractional anisotropy (FA) and mean diffusivity (MD). Background: Dementia develops in about 80[percnt] of PD patients in longitudinal studies. Abnormalities in WM may contribute to PD cognitive impairment and can be identified with neuroimaging techniques. Thus, DTI holds promise as a biomarker for PD cognitive decline. Methods: Sixty-three PD patients underwent clinical/neuropsychological evaluations, T1- and diffusion-weighted magnetic resonance imaging brain scans, and cognitive classification by Movement Disorder Society criteria (cognitively normal (PD-NC), n=20; mild cognitive impaired (PD-MCI), n=28; demented (PDD), n=15). DTI data were processed with mrDiffusion, and whole-brain comparisons of the resulting smoothed FA and MD maps, controlling for PD duration, were analyzed in SPM8 (p<0.001, uncorrected, k=10). Results: The groups differed in PD duration (mean [SD]: PD-NC 8.8 [3.6], PD-MCI 9.4 [4.2], PDD 13.4 [5.5] years, p=0.007), but not in gender, age (73.4 [6.2] years) or education (15.3 [3.1] years). The PD-MCI group showed decreased FA in frontal, temporal, parietal, and occipital lobes, including the anterior corona radiata, anterior thalamic radiation, inferior fronto-occipital fasciculus, and uncinate fasciculus, and increased MD in frontal, parietal, and temporal lobes, including the superior longitudinal fasciculus, compared to PD-NCs. The PDD group had decreased FA in similar regions but also the posterior corona radiata, and increased MD in frontal, temporal/parietal, and limbic lobes, including corpus callosum splenium and superior longitudinal fasciculus, compared to PD-NCs. Comparisons of PD-MCI and PDD groups revealed no significant FA/MD differences. Conclusion: WM microstructural abnormalities occur in cognitively impaired PD patients, particularly in regions underlying attention/working memory, executive function, memory, and visuospatial processing. Furthermore, greater disruption of posterior WM pathways may signify PD cognitive decline.

The Madison Paradox and the Low Cost of Reducing Special-Interest Legislation

Abstract While Madison concluded that there was no solution to the problem of special-interest group influence over politics, we argue that individuals motivated by altruism could contribute money in support of general-interest legislation and offset the pernicious influence of interest groups. We estimate the effect that PAC contributions had on policy outcomes in the House of Representatives and then calculate how much it would cost for a civic-minded altruist to change the outcome. We conclude that buying policy outcomes in the House of Representatives is relatively cheap and that altruism may thus provide a method of improving government policy decisions.
I/O-Conscious Tiling for Disk-Resident Data Sets

This paper describes a tiling technique that can be used by application programmers and optimizing compilers to obtain I/O-efficient versions of regular scientific loop nests. Due to the particular characteristics of I/O operations, straightforward extension of the traditional tiling method to I/O-intensive programs may result in poor I/O performance. Therefore, the technique proposed in this paper customizes iteration space tiling for high I/O performance. The generated code results in huge savings in the number of I/O calls as well as the data volume transferred between the disk subsystem and main memory.
Enhancing channel rendezvous in cognitive radio networks with directional antennas

In cognitive radio (CR) networks, channel rendezvous is a significant operation for two secondary users (SUs) to find a common available channel and establish a link between them. Currently, all previous channel rendezvous designs make the same assumption to ensure that the channel rendezvous process is successful: there must exist at least one common available channel between the SU transmitting pair. However, this assumption is not always feasible. When the number of primary users (PUs) is large, there could be no common available channel between two SUs. This issue results in serious problems in successfully implementing channel rendezvous in CR networks. In this paper, a framework is proposed to tackle this issue by using directional antennas instead of traditionally used omni-directional antennas. Our proposed framework aims to ensure that the probability that the SU pair have at least one common available channel is larger than a pre-defined threshold. Meanwhile, given a channel rendezvous scheme, the average channel rendezvous delay is minimized. Simulation results show that the proposed framework significantly outperforms the scenario with omni-directional antennas in terms of the probability of successful channel rendezvous when the number of PUs is large. To the best of our knowledge, this is the first paper that utilizes directional antennas to enhance the channel rendezvous performance in CR networks.
Sub-milliwatt integrated oven for temperature stable laterally vibrating piezoelectric MEMS resonators

This paper reports the design and demonstration of an integrated oven for aluminum nitride (AlN) piezoelectric MEMS resonators that enables device heating from −40°C to +85°C with a power consumption as low as 368µW - the lowest ever recorded for MEMS resonators. The same resonators exhibit quality factors (Q) as high as 4,459. In this work, RF power delivery is decoupled from resonator supporting beams, hence alleviating the trade-off between power consumption and Q-factor; moreover, heaters are placed externally to the resonator body, hence eliminating the deleterious effects of serpentines on the acoustic properties of the device. More importantly, this ovenization technique is independent of the resonator geometry, so it is broadly applicable to any resonator frequency (70MHz to 1.16GHz in this work). This demonstration constitutes a fundamental stepping stone in enabling temperature stable oscillators with extremely low power consumption.
Distribution, assemblage, capacity: new keywords for masculinity?

Performance and performativity have been the watchwords of gender studies for many years now. What new vocabularies might invigorate the study of Renaissance masculinities? This essay suggests that notions of distribution, assemblage and capacity might help break recent logjams in gender studies and allow greater attention to the social complexities of masculinity as it is constituted in association with a wide range of bodies, life forms and objects.
Smart integral control

A method of achieving integral action with regard to disturbances and unknown constant parameters is presented. The method is similar to Johnson's (1974) "disturbance accommodating control" but is structured so that the disturbance correction or parameter estimation function can be designed without affecting the disturbance-free control. Simulation examples illustrate the method for a one-degree of freedom servo with a randomly-varying load disturbance, and for a two-degree of freedom servo with two sources of friction.
The persistence of populations facing climate shifts and harvest

Many species are expected to shift their geographic distribution as climates change, and yet climate change is only one of a suite of stressors that species face. Species that might, in theory, be able to shift rapidly enough to keep up with climate velocity (the rate and direction that isotherms move across the landscape) may not in actuality be able to do so when facing the cumulative impacts of multiple stressors. Despite empirical reports of substantial interactions between climate change and other stressors, we often lack a mechanistic understanding of these interactions. Here, we developed and analyzed a spatial population dynamics model to explore the cumulative impacts of climate with another dominant stressor in the ocean and on land: harvest. We found that critical rates of climate velocity and harvest depend on the growth rate and dispersal kernel of the population, as well as the magnitude of the other stressor. This allowed us to identify conditions under which harvesting and climate velocity...

Hedgehog signaling stimulates the formation of proliferating Müller glia-derived progenitor cells in the chick retina

Muller glia can be stimulated to de-differentiate and become proliferating progenitor cells that regenerate neurons in the retina. The signaling pathways that regulate the formation of proliferating Muller glia-derived progenitor cells (MGPCs) are beginning to be revealed. The purpose of this study was to investigate whether Hedgehog (Hh) signaling influences the formation of MGPCs in the chick retina. We find that Hh signaling is increased in damaged retinas where MGPCs are known to form. Sonic Hedgehog (Shh) is normally present in the axons of ganglion cells, but becomes associated with Muller glia and MGPCs following retinal damage. Activation of Hh signaling with recombinant human SHH (rhShh) or smoothened agonist (SAG) increased levels of Ptch1, Gli1, Gli2, Gli3, Hes1 and Hes5, and stimulated the formation of proliferating MGPCs in damaged retinas. In undamaged retinas, SAG or rhShh had no apparent effect upon the Muller glia. However, SAG combined with FGF2 potentiated the formation of MGPCs, whereas SAG combined with IGF1 stimulated the nuclear migration of Muller glia, but not the formation of MGPCs. Conversely, inhibition of Hh signaling with KAAD-cyclopamine, Gli antagonists or antibody to Shh reduced numbers of proliferating MGPCs in damaged and FGF2-treated retinas. Hh signaling potentiates Pax6, Klf4 and cFos expression in Muller glia during the formation of MGPCs. We find that FGF2/MAPK signaling recruits Hh signaling into the signaling network that drives the formation of proliferating MGPCs. Our findings implicate Hh signaling as a key component of the network of signaling pathways that promote the de-differentiation of Muller glia and proliferation of MGPCs.
SIMPLIFIED DERIVATION OF THE BINARY COLLISION EXPANSION AND ITS CONNECTION WITH THE SCATTERING OPERATOR EXPANSION

The binary collision expansion for the density matrix of a system of N particles with pair interaction was derived by Huang, Lee, and Yang by expansion in the interaction and subsequent summation over terms represented by certain classes of diagrams. A simpler derivation has been obtained by the use of the N(N--1)/2 integral equations which relate the density matrix of the system to the density matrices of systems in which one pair of particles interacts. Successive substitation of the integral equations into each other yields an expansion which by a trivial additional step becomes the binary collision expansion. Our derivation shows also that the binary collision expansion is the Laplace inverse of the coordinate representation of the expansion in terms of scattering operators. (auth)
Managing Insurance Company Financial Statements to Meet Regulatory and Tax Reporting Goals

This study investigates the extent to which property-casualty insurers select levels of loss reserves, net capital gains, and net stock transactions to meet solvency and tax reporting goals. Insurer solvency is reflected in financial measures known as IRIS (Insurance Regulatory Information System) ratios. IRIS ratios are generally enhanced by underestimating loss reserves, accelerating the realization of capital gains, postponing the realization of capital losses, issuing stock, and cutting dividends. Taxable income is reduced by reporting higher reserves and lower net capital gains on investments. We use simultaneous equations to model the three discretionary choices individually, while controlling for potential tradeoffs among the decisions. During the sample period of the study (1990-95), there is a shift in the regulatory environment that we argue tends to reduce incentives to meet IRIS goals. Specifically, risk-based capital (RBC) requirements were adopted in 1994. Although IRIS ratios continued to be used for solvency screening, their effect is expected to be diluted in the post-RBC period. Our results provide qualified support for this claim. Evidence of the phenomenon is stronger when the choice variables are net capital gains and stock transactions, and weaker when loss reserves are considered. Two of the three discretionary choices affect taxable income: loss reserves and capital gains. We find that tax incentives are significantly associated with the loss reserve estimate throughout the sample period. In contrast, our results are only weakly consistent with the view that capital gains are timed to achieve tax relief.
A modified method of moments approach to the solution of scattering equations

Abstract A modified form of the method of moments is shown to be an effective procedure for obtaining iterative solutions to linear integral equations of the form ¦ψ〉 = ¦φ〉 + λVG¦ψ〉 which appear frequently in quantum scattering theory. After N iterations, this method gives the [N, N−1] Pade approximant to the matrix element M = 〈φ¦G¦ψ〉 . This matrix element is often of physical interest. Other Nth order matrix elements are rational functions of λ having the same denominator as the approximation to M . They agree with the Born series to order N. This approach is therefore more efficient than the more familiar Fade method at summing the iterates of the scattering equations, but requires little additional computional effort. A numerical example using the Lippmann-Schwinger equation exhibits an exponential convergence rate. Useful measures of convergence are obtained.
Interactions between the salt marsh grass Spartina patens, arbuscular mycorrhizal fungi and sediment bacteria during the growing season

Abstract The interaction between the salt marsh plant Spartina patens , arbuscular mycorrhizal fungi (AMF) and bacteria in salt marsh sediment was examined in a long-term arbuscular mycorrhizas (AM) suppression study by applying the systemic fungicide benomyl to field-collected sediment cores with and without S. patens plants. Microbial populations were sampled four times corresponding to major plant phenological stages (dormancy, vegetative growth, reproduction, and senescence) previously linked to changes in microbial populations under field conditions. Benomyl-treatment of soil cores significantly suppressed AM colonization on S. patens , keeping values relatively consistent throughout the growing season (11.5%) whereas plants in non-treated cores experienced seasonal increases and declines in AM colonization (26.6% during vegetative growth to 11.5% during dormancy). Soil physicochemical parameters were not affected by benomyl application. In unvegetated cores, no benomyl- or seasonal effects were displayed by cell numbers and specific biomass of DAPI-stained organisms, members of the domain bacteria and here especially members of the α-, β-, γ- and δ-subdivisions of proteobacteria that were the most abundant bacterial groups. In vegetated cores, the microbial community as well as specific bacterial populations were at least twice as large in terms of number and biomass than in samples from unvegetated cores with significant seasonal changes for DAPI-stained cells, for members of the domain bacteria and for members of the α- and γ-subdivisions of proteobacteria. In benomyl-treated cores, the population of γ-subdivision of proteobacteria was significantly smaller than in non-treated cores, and a positive association was found between this bacterial group and root length colonized by AM suggesting that AM-suppression can affect populations of specific soil bacterial populations in salt marsh sediment. Benomyl-treatment had no effect on the diversity of N-fixing bacteria as evidenced by PCR-RFLP analysis, but seasonal changes were noted in vegetated cores with populations during active plant growth substantially different from populations during dormancy and senescence.
