Combining Diving and Reflected Waves for Velocity Model Building by Waveform Inversion

Field: Earth and Planetary Sciences (Physical Sciences)

Summary Full Waveform Inversion (FWI) aims to reconstruct high-resolution subsurface models from the full wavefield, which includes diving waves, subcritical reflections and short-spread reflections. Most of the successful applications of FWI have been driven by the information carried out by diving waves and subcritical reflections to build the long-to-intermediate wavelengths of the velocity structure. Alternative approaches have been recently revisited to retrieve this long-wavelength content from short-spread reflections only using some prior knowledge of the reflectivity. The present study presents a unified formalism, which aims to update the low wavenumbers of the velocity model by joint inversion of the diving waves and the full reflected wavefield. The method relies on an explicit scale separation between a smooth velocity macromodel and reflectivity, which is assumed to be known, and an explicit data separation between the short-spread reflections and the wide-angle arrivals (i.e., diving waves and subcritical reflections). Applications on simple layered models and a synthetic Valhall model show how the low-wavenumber content of the subsurface is emphasized at all depths by keeping only the transmission wavepaths generated by full wavefields in the gradient of FWI.
Contradictory Trends in Work Organization in the Banking Industry

Field: Business, Management and Accounting (Social Sciences)

Zusammenfassung: Der Aufsatz diskutiert neue Entwicklungstrends der Arbeitsgestaltung im Bankgewerbe vor dem Hintergrund veranderter, marktorientierter Formen der Unternehmenssteuerung. Konkret werden Arbeitszeit- und Vergutungssysteme betrachtet, momentan die Kernbereiche der Arbeitspolitik in Banken. Anknupfend an aktuelle industriesoziologische Debatten wird nach dem Zusammenhang von Arbeitspolitik und Unternehmenssteuerung gefragt. Fuhrt eine finanzialisierte indirekte Steuerung uber Kennziffern zu arbeitspolitischen Ruckschritten? Diese Frage wird differenziert beantwortet. In den untersuchten Fallen ist die Arbeitsgestaltung ein integrierter Bestandteil neuer Steuerungskonzepte. Partizipative Arbeitsgestaltung gilt als Triebkraft, nicht als Hindernis auf dem Weg zur indirekten Steuerung. Trotzdem sind Widerspruche zwischen indirekter Steuerung und partizipativer Arbeitsgestaltung unverkennbar. Diese Widerspruche ergeben sich aus der Unvereinbarkeit zentraler Vorgaben mit dezentralen Verhandlungsprozessen. Die indirekte Steuerung hebelt die diskursive Steuerung aus, weil sie den dezentralen Einheiten die Entscheidungsspielraume uber Ressourcen verweigert. Dies ist letztlich mikropolitisch als Machtproblem in den Unternehmen zu werten.
Solution of Assignment Problem of Restriction of Qualification

Field: Mathematics (Physical Sciences)

The problem of whether someone qualifies for a job in actual assignment is often met. In this paper, a mathematical model of the assignment problem with restriction of qualification is set. With the method, a method of deciding the existence of a solution of this problem is given by transforming the beneficial matrix into the decision one; furthermore, the beneficial matrix is transformed into solution one when the problem has a solution and then the assignment problem with restriction of qualification is transformed into the traditional assignment one. At last, we testify this method is effective with on number example.

Purification of 6-phosphogluconolactonase from bass (Dicentrarchus labrax L.)liver.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The enzyme 6-phosphogluconolactonase (EC 3.1.1.31) is present at high levels in bass liver. The enzyme has been purified 1253-fold with an overall yield of 78% in a procedure involving dye-ligand and gel filtration chromatographies. The purified enzyme which is homogenous by all the usual criteria has a molecular weight of about 30,000. It exhibits a considerably high catalytic efficiency with Kcat/Km of 8.5 x 10(7) M-1.s-1 at 22 degrees C. Its activity illustrates the importance of glucose oxidation via the pentose phosphate pathway relative to glycolysis in this organism.
Characteristics of Erectile Dysfunction as a Function of Medical Care System Entry Point

Field: Medicine (Health Sciences)

The scientific literature on the treatment of penile erectile dysfunction contains numerous contradictory reports on the relative frequency of organic causes of impotence and the treatment results of behavioral sex therapy. One explanation for these contradictory findings is the hypothesis that different investigators are studying different subsamples of the symptomatic population. This study investigated differences in characteristics of men who initially consulted a urologist with a complaint of impotence versus those who self-referred themselves to a sexual dysfunction clinic. Self-referred sexual dysfunction patients were more often white, more often had psychogenic etiologies to their difficulties, were more often of higher socioeconomic class, and had a much better response to psychological interventions. This study suggests that future studies concerning the etiology and treatment of impotence need to specify population characteristics such as referral source and screening criteria. It may be necessary to develop alternative treatment techniques for men who present to nonpsychiatric sources for help with psychogenic impotence.
Socio-spatial transformation of neighbourhoods around rail transit stations: an experience from Tehran, Iran

Field: Social Sciences (Social Sciences)

While increasing evidence suggests that rail infrastructure plays a structuring role in shaping and transforming cities and regions over time, empirical studies on the simultaneous development of rail infrastructure and socio-spatial transformation of surrounding neighbourhoods, especially at a local scale, are scarce. The main aim of the article is to evaluate the transformation of neighbourhoods around rail transit stations, as well as provide a possible explanation of how neighbourhoods can be differently affected by the presence of rail stations. Based on a longitudinal dataset (2006–16) and using a Difference-in-Differences (DID) model and Multivariate Analysis of Variance (MANOVA), a comparative analysis of the Tehran Metro Rail System (TMRS) is conducted between high-income neighbourhoods and low-income neighbourhoods of the city. The results yield that the northern, high-income neighbourhoods and the southern, low-income neighbourhoods of Tehran have been transformed heterogeneously in terms of socio-demographic factors, land-use conditions and renewal processes. The findings also indicate that the mixed estimated transformation of neighbourhoods around TMRS’s stations could be explained by the contextual factors of the northern and southern study settings in Tehran, including land-use characteristics and socio-economic factors.
Feasibility and benefit assessments of hybrid hydrogen fuel cell and battery configurations on a regional turboprop aircraft

Field: Energy (Physical Sciences)

View Video Presentation: https://doi.org/10.2514/6.2022-3290.vid Abstract – This paper will be exploring different hybrid configurations and comparing their fuel burn benefits in an attempt to identify whether hybrid electric, hybrid with hydrogen fuel cells or a combination of the two will bring the aviation sector closer towards decarbonization. A notional turboprop regional aircraft based on the DeHaviland Dash 8 Q 400 was modeled using public domain data to create a baseline for present day. Then, technologies were infused to create a 2030 BIC vehicle, and finally, hybrid architectures were implemented to develop a hybrid 2030 BIC vehicle. An existing parallel hybrid electric architecture showed 10.3% fuel burn benefit compared to the baseline for a design mission of 1100 nmi. In this paper the polymer electrolyte membrane hydrogen fuel cell was infused for the same mission and the fuel burn benefits were calculated in addition to a combination of the PEMFC and the lithium-ion batteries for the same mission. Finally, seeing that the notional turboprop was based on the DASH 8 Q400, the typical mission fuel burn benefits were calculated for each of the configurations and were compared to the baseline.
Usefulness of the SYNTAX Score for Predicting Clinical Outcome After Percutaneous Coronary Intervention of Unprotected Left Main Coronary Artery Disease

Field: Medicine (Health Sciences)

Background— The SYNTAX score (SXscore) has been proposed recently as a valuable tool to characterize the coronary vasculature prospectively with respect to the number of lesions and their functional impact, location, and complexity. However, the prognostic value of SXscores in patients undergoing percutaneous coronary intervention of the left main artery has not been validated. Methods and Results— We applied the SXscore in 255 consecutive patients who underwent percutaneous coronary intervention for left main disease and explored its performance with respect to their clinical outcome. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the SXscore and the incidence of cardiac mortality, the primary end point of the study, and major adverse cardiac events (MACE). At 1 year, the SXscore significantly predicted the risk of cardiac death (hazard ratio, 1.12/unit increase; 95% CI, 1.06 to 1.18; P <0.001) and MACE (hazard ratio, 1.59/unit increase; 95% CI, 1.02 to 2.48; P =0.043). After adjustment for potential confounders, a higher SXscore remained significantly associated with cardiac mortality (adjusted hazard ratio, 1.15; 95% CI, 1.05 to 1.26; P =0.003) and MACE (adjusted hazard ratio, 1.06; 95% CI, 1.02 to 1.10; P =0.005). C-indexes for SXscores in terms of cardiac death and MACE were 0.83 and 0.64, respectively. Using classification tree analysis, discrimination levels of 34 and 37 were identified as the optimal cutoff to distinguish between patients at low and high risk of cardiac death and MACE, respectively. Conclusions— The SXscore is a useful tool to predict cardiac mortality and MACE in patients undergoing percutaneous revascularization of the left main coronary artery.
Direct and Correlated Responses to Four Cycles of Divergent Selection for Heading Date in Barley*

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract In order to investigate the direct and correlated responses to selection for heading date in barley, two F 2 populations were subjected to four cycles of divergent selection. For each cross, eight populations selected for earliness (from 1E to 4E) and for lateness, (from 1L to 4L) and four unselected populations (1, 2, 3 and 4 SSD) were obtained and than compared together with parental lines. Selection caused a change greater than one day/cycle in Doth directions, and the cumulative responses were ‐5.4 and ‐5,9 days in the direction of earliness, 7.7 and 7,1 days in the opposite direction. Such results suggest that in the two base populations the heading, date is under the control of a polygenic system with prevailing additive effects and a slight directional dominance toward earliness. Early populations showed a reduction of ear moisture and an increase of plant height, ear extrusion, kernel weight and harvest index, whereas late populations showed the opposite changes. Grain yield was linearly reduced by selection for lateness, whereas no substantial change was evidenced in the opposite direction, so that 4E significantly out‐yielded 4L in both crosses.
Decay Channels of Core-Excited Molecular States in Cl2, HCl and H2S

Field: Chemistry (Physical Sciences)

Decay channels in HCl, H2S and Cl2 molecules after excitation of 2p electrons to the first empty molecular orbitals have been studied using electron spectroscopy with synchrotron radiation. Dissociation followed by Auger decay in the excited fragments has been found to be the main decay channel in HCl and H2S whereas in Cl2 molecular resonance Auger process seems to play a major role in the decay of molecular resonance states.
Optimal indication of thyroglobulin measurement in fine-needle aspiration for detecting lateral metastatic lymph nodes in patients with papillary thyroid carcinoma

Field: Medicine (Health Sciences)

BACKGROUND: \nThe purpose of this study was to evaluate optimal indication of thyroglobulin (Tg) measurement in fine-needle aspiration (FNA) for detecting lateral metastatic lymph nodes in patients with papillary thyroid carcinoma (PTC). \nMETHODS: \nWe performed a retrospective study of 241 lymph nodes of 220 patients who underwent ultrasound-guided FNA with Tg in FNA (FNA-Tg) washout fluid measurements for suspicious lymph nodes. \nRESULTS: \nOn multivariate analysis, hyperechogenicity, cystic change, presence of calcifications, and peripheral vascularity were independent factors predictive of lymph node metastasis. After adding FNA-Tg, sensitivity and accuracy were significantly increased when the lymph node had 1 or 2 suspicious ultrasound features. However, sensitivity and accuracy were not significantly increased when the lymph node had multiple suspicious ultrasound features. \nCONCLUSION: \nAdditional FNA-Tg can help diagnose a metastatic lymph node with 1 or 2 suspicious ultrasound features. However, additional FNA-Tg is not beneficial in lymph nodes with highly suspicious ultrasound features, in which FNA alone is sufficient for diagnosis of predictive of lymph node.
33-GHz monolithic cascode AlInAs/GaInAs heterojunction bipolar transistor feedback amplifier

Field: Engineering (Physical Sciences)

Microwave cascode feedback amplifiers with 8.6-dB gain and DC to 33-GHz bandwidth were developed. The amplifiers utilize AlIn-As/GaInAs heterojunction bipolar transistors having f/sub max/=70 GHz and f/sub tau /=90 GHz. Because of the significant collector-base feedback time constant the cascode configuration provides a large improvement in amplifier bandwidth, but a low-impedance bias node must be provided for the common-base transistor. An active bias network was thus used which eliminates the need for on-wafer Si/sub 3/N/sub 4/ bypass capacitors.< >
Phase‐Change Memory Films: Low‐Dimensional Single‐Cation Formamidinium Lead Halide Perovskites (FAm+2PbmBr3m+2): From Synthesis to Rewritable Phase‐Change Memory Film (Adv. Funct. Mater. 17/2021)

Field: Materials Science (Physical Sciences)

In article number 2011093, Youngjong Kang and co-workers present a simple in situ quenching-assisted fabrication technique for FAm+2PbmBr3m+2 films possessing wide dimensional controllability from 1D to 3D structures. The FAm+2PbmBr3m+2 exhibits an unusual (110)-oriented structure that shows a phase transition to 3D FAPbBr3 under humidity and ultra-violet light exposure. The phase transition behavior of FAm+2PbmBr3m+2 is utilized for the phase-change memory films.
Symbolic computation of electron-proton to slepton-squark scattering cross sections based on a left-right supersymmetric extension of the standard model

Field: Physics and Astronomy (Physical Sciences)

The calculation of the cross section of supersymmetric processes based on a left-right supersymmetric extension of the standard model is presented. The Feynman diagrams for the neutralino-quark-squark and chargino-quark-squark are written down, and the production of sleptons and squarks resulting from the t-channel exchange of neutralinos and charginos in electron-proton scattering is analyzed. The symbolic programming language Mathematica ® , is used to develop a program to generate a symbolic representation of the invariant amplitude for these processes. Differential cross sections, based on numerical values of the free parameters of the left-right supersymmetric model, are generated.
[Conservative treatment of kidney cancer by cryoablation and radiofrequency].

Field: Medicine (Health Sciences)

Cryoablation and radiofrequency are minimally invasive techniques allowing resection of the tumour by application of physical means (cold or heat) to the centre of the lesion, rather than strictly surgical resection. The incision is usually percutaneous but can be laparoscopic in certain indications. Indications are currently limited to exophytic renal tumours < 40 mm, situated away from structures of the hilum (vessels and renal pelvis) and gastrointestinal structures in patients > 70 years or in the context of previously operated hereditary renal carcinoma (von Hippel Lindau disease). The results of the first series are encouraging, although more contradictory for radiofrequency probably due to the heterogeneous equipment (electrodes, generator, frequency, etc.). The complication rate is low. A PHRC national multicentre randomized study is currently underway to compare the functional and oncological results of radiofrequency and conservative surgery.
