6-bit 1-GS/s Partially Active Flash ADC with Comparator Offset Correction

This paper presents a low-power 6-bit 1 GS/s partially active flash analog-to-digital converters (ADC) in 65-nm CMOS technology. A novel comparator offset correction technique is proposed, which does not require additional foreground calibration cycles. The partially active second-stage comparison is employed for power efficiency. A third-stage comparison is introduced for offset correction using fifteen low-offset comparators, out of which two are activated. The 0.5-bit redundancy from the first-stage provides the tolerance to track-and-hold (T/H) buffer settling error for high-speed applications. The simulation results show that the ADC achieves a signal-to-noise and distortion ratio (SNDR) of 36.36 dB and a spurious-free dynamic range (SFDR) of 48.65 dB at a Nyquist frequency of 500 MHz with the power consumption of 13.98 mW.
Trends in Gynecologic Carcinosarcoma Based on Analysis of the Surveillance Epidemiology End Result (SEER) Database

Carcinosarcomas (malignant mixed Mullerian tumors) of a female genital organ are rare tumors associated with a poor survival. The purpose of this study was to identify site-specific differences in the incidence and prognosis in carcinosarcomas originating in the uterus, cervix, or ovary. The data of patients with gynecologic carcinosarcomas were extracted from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2016. The characteristics of gynecologic carcinosarcomas were compared using Pearson X2 and Fisher’s exact tests. Kaplan–Meier models were used for cause-specific survival (CSS) analysis. The cohort included 7086 females, including 5731 cases of uterine carcinosarcoma, 161 cervical carcinosarcomas, and 1193 ovarian carcinosarcomas. The age-adjusted incidence rates of uterine, cervical, and ovarian carcinosarcoma were 3.9, 0.1, and 0.6 per 1,000,000, respectively. In the distribution of carcinosarcoma incidence by race, compared with the uterus or cervix, those originating from the ovary were unequally distributed in Caucasians (84.4% versus 69.6%, 67.7%; p < 0.001). The incidence of uterine carcinosarcoma steadily increased over time, from 2.2 in 2000 to 5.5 in 2016 (per 1,000,000), while cervical or ovarian carcinosarcoma showed no significant difference in incidence. The five-year CSS rates based on the site of origin (uterus, cervix, and ovary) were 39.9%, 33.1%, and 25.8%, respectively. The incidence rates of gynecologic carcinosarcoma, especially uterine carcinosarcoma, are gradually increasing. Although uterine carcinosarcoma is associated with a higher incidence than the others, it has a better prognosis compared with ovarian and cervical carcinosarcoma. The survival rates were worst in ovarian carcinosarcoma.
Current situation, efficacy, and safety of extracorporeal cardiopulmonary resuscitation in China

To the Editor: The survival rate from conventional cardiopulmonary resuscitation (CCPR) of out-of-hospital and in-hospital cardiac arrest ranges from 9% to 20%. Without returning of spontaneous circulation (ROSC) after CCPR, the chance of recovery is very poor. Initiating venoarterial extracorporeal membrane oxygenation in those patients may provide adequate organ perfusion that allows for longer organ viability and permit time for therapies seeking to correct the inciting pathologic event, which is termed extracorporeal cardiopulmonary resuscitation (ECPR). Time to treatment, ECPR-related complications, as well as etiology, have been recognized as themain predictors of survival for ECPR patients. ECPR has been carried out more and more in China, but the information on ECPR application remains unknown. Therefore, we conducted a retrospective survey about the usage of ECPR in China, including patient selection, initiation and management of extracorporeal mechanical ventilation (ECMO), patient outcome, and compared the status during 2017 and 2020.
On the Multiple Sources and Privacy Preservation Issues for Heterogeneous Defect Prediction

Heterogeneous defect prediction (HDP) refers to predicting defect-proneness of software modules in a target project using heterogeneous metric data from other projects. Existing HDP methods mainly focus on predicting target instances with single source. In practice, there exist plenty of external projects. Multiple sources can generally provide more information than a single project. Therefore, it is meaningful to investigate whether the HDP performance can be improved by employing multiple sources. However, a precondition of conducting HDP is that the external sources are available. Due to privacy concerns, most companies are not willing to share their data. To facilitate data sharing, it is essential to study how to protect the privacy of data owners before they release their data. In this paper, we study the above two issues in HDP. Specifically, to utilize multiple sources effectively, we propose a multi-source selection based manifold discriminant alignment (MSMDA) approach. To protect the privacy of data owners, a sparse representation based double obfuscation algorithm is designed and applied to HDP. Through a case study of 28 projects, our results show that MSMDA can achieve better performance than a range of baseline methods. The improvement is 3.4-$15.3$15.3 percent in g-measure and 3.0-$19.1$19.1 percent in AUC.
A Systematic Review of Clinical Psychophysiology of Obsessive–Compulsive Disorders: Does the Obsession with Diet Also Alter the Autonomic Imbalance of Orthorexic Patients?

(1) Background: A new mental illness is attracting the attention of researchers and mental health professionals. Orthorexia nervosa (ON) is a possible new mental disorder, the main symptom of which is an obsessive and insecure focus on healthy foods and consequent compulsive behaviors. There is a common consensus among researchers that ON is considered partly overlapping with obsessive–compulsive disorders (OCDs). (2) Methods: MEDLINE and Scopus were searched for articles published in the last 10 years regarding the psychophysiological aspects of OCD and ON. Eight studies met the eligibility criteria. The inclusion criteria encompassed adults diagnosed with OCD and/or ON. However, only studies involving OCD patients were found. (3) Results: Some research groups have shown that OCD disorders can be considered among anxiety disorders because they are characterized by anxious hyper activation. Other research, however, has shown profiles characterized by low psychophysiological reactivity to stressful stimuli. Despite this, there seems to be a consensus on the poor inhibition abilities, even when activation is low, and the dissociation between cognitive and psychophysiological activation emerged. (4) Conclusions: However discordant, some points seem to bring the researchers to agreement. In fact, there is consensus on conducting a multidimensional assessment that can measure all of the aspects of suffering (cognition, emotion, and behavior) and highlight the poor body–mind integration. This clinical approach would make it possible to propose interventions aimed at treating some mental illnesses such as food obsession that can paradoxically impair the psychophysical balance. Nevertheless, the applied systematizing approach to existing studies on ON is very much needed for better understanding of the psychophysical nature of this new mental illness and its implications for prevention and treatment.
A Needs-Based Evaluation Of ESP Materials In The Bachelor Program Of Applied Linguistics At An LPDR University

- The present study aims to evaluate the current ESP materials used in a LPDR university from students’ perspectives as well as propose changes to the learning documents based on better considerations of students’ needs. As an exploratory study, it employed questionnaires as the primary research instrument to collect 100 students’ opinions of the in-use ESP materials in the mentioned university and their expectations for the future learning materials. The findings indicated that ESP materials should be revised to ensure more access to communicative English teaching and more opportunities for students’ professional learning. A need-based proposal of the ESP materials was introduced to the learners for their initial ideas of the changes. The result suggested that students were satisfied with the proposed changes of the new ESP materials, which could be the first starting point to the revision and design of the new ESP materials in that LPDR university.
Ultrathin single-crystalline-silicon cantilever resonators: Fabrication technology and significant specimen size effect on Young’s modulus

Ultrathin resonant cantilevers are promising for ultrasensitive detection. A technique is developed for high-yield fabrication of single-crystalline-silicon cantilevers as thin as 12 nm. The formed cantilever resonators are characterized by resonance testing in high vacuum. Significant specimen size effect on Young’s modulus of ultrathin (12–170 nm) silicon is detected. The Young’s modulus decreases monotonously as the cantilevers become thinner. The size effect is consistent with the published simulation results of direct-atomistic model, in which surface effects are taken into consideration.
Mathematical modelling of the avian flight power curve

Just as man has long pursued the challenge of emulating the 2ight of birds, so has a goal of the mathematician been to model how that 2ight works. Scienti(c studies of bird 2ight are among the most signi(cant early contributions to the literature of biophysics [1–4]. There were many attempts to construct sophisticated mathematical and physical models of avian 2ight mechanics long before there was any consensus about the fundamental matter of how a wing generates aerodynamic force [5–12]. Etienne Marey’s extensive studies of birds [13] were among the (rst recognition that wings generate lift perpendicular to an air2ow striking the lower surface of the wing at a small angle of incidence, but agreement on the physical mechanisms and adequate mathematical tools to describe them were not to be achieved until around 1915, a signi(cant time after birds had been copied with the (rst simple 2ying models [14], and well after the development of eCective aircraft. Each of the three scientists who independently developed components of the vortex model of the wing [15–19] had carried out extensive observations of animal 2ight, and their ideas came together only after detailed studies of birds undertaken by themselves and their predecessors (among many others, Cayley [20], Lilienthal [21] and Marey [13] are pre-eminent). Gibbs–Smith [22; 23], Hart [24], Anderson [25] and MusF ee Marey [26] have reviewed the links between the development of aeronautics and early work on animal 2ight. A key target of the (rst work on animal 2ight and in aeronautics was to establish the underlying physical principles by which a wing generates lift. A secondary goal was to determine the magnitudes of the forces generated by the wings and of the power consumed in 2ight, in the hope that values for birds could be extrapolated to predict the performance of a man-carrying or man-powered machine. Simultaneously bird design was studied to obtain some idea of the optimum dimensions for aircraft [27–29]. Since aeronautics came of age, work on natural aerodynamics shifted its focus, into the study of how the animals themselves 2y, of how 2ight has evolved, and of the ways in which it operates as a component of the animals’ life histories. Work on bioaerodynamics remains closely allied to modern low-speed aeronautics, despite the widely diCering natures of the scienti(c and engineering problems
Some Information Theoretic Saddlepoints

In order to study communication in the presence of jamming (or vice-versa), one can formulate a two person zero sum game with mutual information as the payoff function. Since mutual information is convex-concave in just the right way, one often finds saddlepoint strategies (which are simultaneously optimal for both players). In this paper we shall discuss these saddlepoints for four distinct cases: Additive noise, average power constraints, and any combination of “hard”/“soft” input/output quantization. One of these cases (soft/soft) has been previously studied (Shannon/Dobrushin/Blachman), but the other three appear to be new.
J = w production in p+p and p+Pb collisions at ultrarelativistic energies

The production of J = w mesons in p ? p and p ? Pb collisions is studied in the framework of color-glass condensate together with a simple color evaporation model. Considering the nuclear effects with the Glauber–Gribov approach, we calculate the cross section and the nuclear modiﬁcation factor of forward J = w production in p ? Pb collisions at ﬃﬃ s p ¼ 5 : 02 TeV. Then, the backward J = w production in p ? Pb collisions at ﬃﬃ s p ¼ 8 : 16 TeV is also analyzed. In our calculation, the phenomenology KLR-AdS/CFT model and the rcBK approach, which are valid at a small x , are used to calculate the three-point function. It is shown that the theoretical results ﬁt well with the experimental data from ALICE and LHCb.
Designing large-eddy simulation of the turbulent boundary layer to capture law-of-the-wall scalinga)

Law-of-the-wall (LOTW) scaling implies that at sufficiently high Reynolds numbers the mean velocity gradient ∂U/∂z in the turbulent boundary layer should scale on u∗/z in the inertia-dominated surface layer, where u∗ is the friction velocity and z is the distance from the surface. In 1992, Mason and Thomson pointed out that large-eddy simulation (LES) of the atmospheric boundary layer (ABL) creates a systematic peak in ϕ(z)≡(∂U/∂z)/(u∗/z) in the surface layer. This “overshoot” is particularly evident when the first grid level is within the inertial surface layer and in hybrid LES/Reynolds-averaged Navier–Stokes methods such as “detached-eddy simulation,” where the overshoot is identified as a “logarithmic layer mismatch. ” Negative consequences of the overshoot—spurious streamwise coherence, large-eddy structure, and vertical transport—are enhanced by buoyancy. Several studies have shown that adjustments to the modeling of the subfilter scale (SFS) stress tensor can alter the degree of the overshoot. A com.
Numerical modeling of Kelvin–Helmholtz instability using smoothed particle hydrodynamics

This paper presents a Smoothed Particle Hydrodynamics (SPH) solution for the Kelvin–Helmholtz Instability (KHI) problem of an incompressible two‐phase immiscible fluid in a stratified inviscid shear flow with interfacial tension. The time‐dependent evolution of the two‐fluid interface over a wide range of Richardson number (Ri) and for three different density ratios is numerically investigated. The simulation results are compared with analytical solutions in the linear regime. Having captured the physics behind KHI, the effects of gravity and surface tension on a two‐dimensional shear layer are examined independently and together. It is shown that the growth rate of the KHI is mainly controlled by the value of the Ri number, not by the nature of the stabilizing forces. It was observed that the SPH method requires a Richardson number lower than unity (i.e. Ri≅0.8) for the onset of KHI, and that the artificial viscosity plays a significant role in obtaining physically correct simulation results that are in agreement with analytical solutions. The numerical algorithm presented in this work can easily handle two‐phase fluid flow with various density ratios. Copyright © 2011 John Wiley & Sons, Ltd.
Pathways to social support: IVF patients’ motivation toward peers and selection preferences

Abstract Infertility rates are increasing internationally, and its treatment, in-vitro fertilization (IVF) imposes stress on women as primary patients. In this study, led by a researcher with lived experience in infertility, we seek to uncover the pathways that lead IVF patients toward peer support; mainly what precipitates patients’ decisions to seek peer support and how they select their peer. Having interviewed 23 IVF patients, we found that prior to disclosing to a peer, women reflect on information about their condition and their personal support needs and reconcile support gaps within their couple and social circles as they gauge their personal motivation to seek peer support. The demands of IVF compel patients to gravitate toward other women with shared experience. Prior to disclosure, patients consider diverse points of connection as well as desirable peer traits including previous IVF experience, other common ground and full transparency in a peer’s communication style.
The grammar of standards: Judge-dependence, purpose-relativity, and comparison classes in degree constructions

This dissertation explores the structure and semantics of constructions based on the positive form of gradable adjectives, such as tall, long, interesting or smart. Such forms – and constructions that are based on them – contain an element of semantic indeterminacy regarding the standard of comparison that they make reference to. At the same time, there are a number of phrases that can participate in constructions with such adjectives and remove some of this indeterminacy. Examples include ‘judge’-phrases, as in ‘The ride was fun for John’; purpose-clauses, as in ‘This is a long book to assign’; comparison-class phrases, such as ‘John is tall for a 4-year-old’. The dissertation investigates these constructions, providing a syntactic and semantic analysis for each of them, motivated by an array of empirical cross-linguistic evidence. Despite the apparent similarity between these ‘standard-affecting’ phrases in terms of their overall interpretational effect, the linguistic machinery behind these effects turns out to be very different in each case upon closer examination. The linguistic perspective taken in this dissertation on the problems of the standard of comparison in the positive construction uncovers various intricacies of the standards of gradable predicates and opens up new directions for studying the semantics of adjectives and standards of comparison.
Associations between outpatient treatment and the use of intensive psychiatric healthcare services

The current manuscript examines concurrent and longitudinal associations between the utilization of outpatient and intensive psychiatric services among Medicaid-enrolled youth. Using an administrative dataset of Medicaid claims from 2007 to 2017, youth were included if they were between the ages of 10–18 (M = 13.4, SD = 2.6) and had a psychiatric Medicaid claim (N = 33,590). Psychiatric services were coded as outpatient, emergency department (ED), inpatient, or residential based on Medicaid codes. Logistic regression analyses indicated that the receipt of even one outpatient visit significantly reduced the odds of having an ED, inpatient, and residential visit within 60-, 90-, and 120-day windows. Survival analyses indicated most youth did not have any ED, inpatient, or residential visit following their first outpatient visit. For remaining youth, having an outpatient visit significantly increased the risk of having an ED, inpatient, and residential visit following their initial appointment, which may suggest these youth are being triaged to a more appropriate level of care. Classification accuracy analyses indicated a cutoff of 2 outpatient visits yielded maximum accuracy in determining youth with ED, inpatient, and residential visits. Findings highlight use of outpatient-level services in reducing risk of more intensive service utilization.
The life of a mixed-up model

The effect of surface mixing on the CNO isotopes is studied for different mixing time scales and depths of mixing. The results are applicable to meridional mixing, or any other continuous mixing on the main sequennce. For mixing which is fast compared to the main-sequence lifetime, the depth of mixing is critical in determining the resultant /sup 12/C//sup 13/C ratio. Mixing which is slow compared to the main-sequence lifetime allows one to mix very deeply and not produce too much /sup 13/C. Large /sup 14/N enrichment, however, is produced in the latter case, and the /sup 17/O//sup 18/O ratio changes little. The resulting /sup 12/C//sup 13/C ratio is sensitive to the time scale of mixing.
Pole assignment in a specified disk

The problem of assigning all poles of a closed-loop system in a specified disk by state feedback is considered for both continuous and discrete systems. A state feedback control law is determined by using a discrete Riccati equation. This kind of pole assignment problem is named D -pole assignment, and its relation to the optimal control problem and its robustness properties are discussed. The gain and phase margins for all closed-loop poles to stay inside the specified disk D are determined for the proposed control.
Long Term Evolution (LTE) Network Planning at 700 MHz Frequency in Cipali Toll Road Using Atoll Radio Planning Software

Long Term Evolution (LTE) is the 4th generation technology-based Internet Protocol (IP) which is the development of previous UMTS (3G) and HSPA (3.5G) technologies with speed and spectral efficiency improvements from previous technologies. This research proposed the design of LTE network using a 700 MHz frequency which is the most ideal frequency for LTE in Indonesia, the wide area coverage, bandwidth availability, and small propagation loss value. The 700MHz frequency is expected to be ready in 2020. The 700 MHz- LTE design is implemented along the Cipali toll road with a distance of 116 km. Design refers to the calculation of coverage and capacity dimensions to determine the number of eNodeB. This design was carried out using the Atoll software with the Okumura-Hatta propagation model. Dimensional calculations show that the number of 11-eNodeBs is needed in planning.

A Cross-Validation Approach to Sample Size Determination for Regression Models

Abstract A cross-validation approach to the a priori determination of sample size requirements and the a posteriori estimates of the validity of a derived regression equation is developed for regression models, where sampling from multivariate normal populations is discussed in particular. Tables of sample size estimates are presented for the random model and their applications illustrated. An algorithm is given to obtain tables for the fixed model directly from those for the random case.
