An Ensemble Optimization Strategy for Dynamic Parking-Space Allocation

The individual choices of parkers, based on self-interests, can result in the inefficient use of on-street parking-space resources as well as chaotic parking conditions (e.g., secondary path interweaving). Therefore, an ensemble optimization strategy for dynamic parking-space allocation (EO-DPSA) is proposed for systematically optimizing on-street parking-space use. First, the issue of inefficient parking-space use caused by the individual choice of parkers is investigated. Subsequently, the EO-DPSA technique is developed for optimizing parking-space use from a system level by improving the parking sequence for eliminating parking-entry conflicts. Consequently, the compliance rate of parking guidance is increased, and secondary path interweaving is prevented. Next, the optimization effect of the EO-DPSA technique is validated based on the smart parking data obtained from Guilin City. The obtained results indicate that after optimization via the EO-DPSA method, the parking-space use of 81 parking areas is optimized. Hence, 2.86–66.67% of redundant parking spaces can be discarded in 41 parking areas. In particular, a parking compliance rate of 99.023% is achieved. In addition, 97.82% of the parking phases exhibit better results in avoiding secondary path interweaving after optimization.
Resolvins’ Obesity-Driven Deficiency: The Implications for Maternal–Fetal Health

Since pregnancy is already characterized by mild but significant inflammatory activity in physiological conditions, when complicated by obesity the probability of a persistent inflammatory state increases, with consequent multiple repercussions that add up to the complications associated with acute inflammation. In this context, the role of resolvins, specialized pro-resolving mediators (SPMs), deriving from omega-3 essential fatty acids, may be crucial. Indeed, differential production in numerous high-risk conditions associated with both childbirth and neonatal health, the correlation between maternal omega-3 intake and resolvin concentrations in maternal blood and at the placental level, and the high values found in breast milk in the first month of breastfeeding, are some of the most important hallmarks of these autacoids. In addition, a growing body of scientific evidence supports the lack of SPMs, at the level of immune-metabolic tissues, in the case of obesity. Furthermore, the obesity-related lack of SPMs seems to be decisive in the context of the current outbreak of COVID-19, as it appears to be one of the causes associated with the higher incidence of complications and negative outcomes of SARS-CoV-2 infection. The usefulness of metabolomics in this field appears clear, given that through the metabolome it is possible to observe the numerous and complex interactions between the mother, the placenta and the fetus in order to identify specific biomarkers useful in the prediction, diagnosis and monitoring of the various obstetric conditions. However, further investigations are needed in order to evaluate the possible use of some resolvins as biomarkers of maternal–fetal outcomes but also to establish adequate integration values in pregnant women with omega-3 fatty acids or with more active derivatives that guarantee optimal SPM production under risky conditions.
On Deploying Secondary Networks in Co-Channel Bands with DTV Networks

This paper explores the feasibility and scope of co-channel coexistence between a low data rate Orthogonal Frequency Division Multiplexing (OFDM) secondary network and a digital television (DTV) broadcast network operating in the same area. Since DTV receivers do not transmit, neither the presence nor the impact of interference from the secondary network on these DTV receivers can be known. Consequently, conventional spectrum sensing techniques cannot be employed effectively. This paper proposes to compensate the lack of feedback by combining the available information about population distribution in the region - ranging from coarse population density estimates to accurate geospatial maps - with better estimation of interference using a data-driven technique called Ordinary Kriging. Radio Environment Maps constructed using the Kriging method from field-reported observations from the secondary nodes are used to obtain better accuracy than the conventional statistical models. The estimates are then used to compute communication parameters for each secondary link in terms of power, number of active subcarriers, and active time slots, while keeping the average interference in the DTV network within threshold bounds. Thus, the viability of such co-channel license-exempt operation of secondary networks in the DTV black and grey spaces for low data rate applications in densely populated urban areas and higher data rate capabilities for sparsely populated rural areas is established.
Differentiating Serious and Non-Serious Injury of Marine Mammals: Report of the Serious Injury Technical Workshop

This Technical Memorandum contains summaries of presentations given at the 2007 Serious Injury Technical Workshop. These summaries (sections 3.0-6.0) were prepared by the author(s) of the presentations; therefore, statements and recommendations represent the views and opinions of the respective presenter(s). The summaries do not necessarily represent the views of the workshop Steering Committee or the National Marine Fisheries Service (NMFS). The Steering Committee did not make any substantive changes to the summaries without permission from the author(s). The Steering Committee edited the summaries only to correct grammatical errors and other minor edits. This Technical Memorandum contains summaries of plenary and subgroup discussions that occurred during Days 1-3 of the workshop. While many of the comments and suggestions provided by the individual participants represent shared opinions among the participants, the intent of these discussions was not to reach consensus recommendations. Instead, the intent was to gather input from each individual participant based on his or her expertise and experience. For this reason, the discussions summarized in this Technical Memorandum do not represent consensus recommendations from the workshop participants to NMFS. This Technical Memorandum contains recommendations of Federal Government participants and the workshop Steering Committee concerning the guidance and process for distinguishing serious from non-serious injuries. These recommendations do not represent official NMFS policy. iii Executive Summary Background The Marine Mammal Protection Act (MMPA) section 117 requires the National Marine Fisheries Service (NMFS) to prepare stock assessment reports (SAR) for all stocks of marine mammals that occur in waters under the jurisdiction of the United States. These reports summarize human-caused mortalities and serious injuries to marine mammals by source. In addition, MMPA section 118 requires commercial fisheries to reduce mortality and serious injury of marine mammals to insignificant levels approaching a zero mortality and serious injury rate. This charge requires that NMFS distinguish between injuries that are serious and those that are not serious. NMFS defined " serious injury " in regulations (50 CFR 229.2) as " any injury that will likely result in mortality. " However, the MMPA and its legislative history do not provide guidance on how severe an injury must be to qualify as " serious. " To promote national consistency for interpreting the regulatory definition of serious injury, NMFS convened a workshop in April 1997 to discuss available information related to the impact of injuries to marine mammals incidental to commercial fishing operations (Angliss and DeMaster, 1998).

Considerations on elliptical failure envelope associated to Mohr-Coulomb criterion

Mohr-Coulomb theory is mostly used in civil engineering as it is suitable for soils, rock, concretes, etc., meaning that the theory is generally used for brittle facture of the materials, but there are cases when it matches ductile behaviour also. The failure envelope described by the Mohr-Coulomb criterion is not completely accurate to the real yield envelope. The ductile or brittle behaviour of materials could not be incorporated in a linear envelope suggested by classic stress state theories and so, there have been a number of authors who have refined the notion of yield envelope so that it would fit better to the actual behaviour of materials. The need of a realistic yield envelope comes from the demand that the failure state should be able to be predicted in a fair manner and with as little errors as possible. Of course, certain criteria will be closer to the actual situation, but there is a constant need to unify and refine the limit stress theories in order to avoid problems as defining boundaries of application areas on numerical programs. Mohr-Coulomb's yield envelope is the most used one on programs, can be reduced to Tresca theory when the materials are conducting a ductile behaviour and has a linear simplified form. The paper presents some considerations with respect to the elliptical failure envelope correlated to the Mohr-Coulomb theory. The equations have been rewritten for triaxial situation to describe a more accurate state of stress that is encountered under real conditions in materials. Using the Mohr's circles to define the yield envelope, the calculus has been made in in order to determine the yield stress at tensile tests
Enacting Moving Images

This article highlights ways to relate psychology, neuroscience, and film theory that are underrepresented in the current debate and that could contribute to a new cognitive media theory. First, we outline how neuroscientific approaches to moving images could be embedded in the embodied, enactive cognition framework and recent predictive processing theories of the brain. Within this framework, we understand filmic engagement as a specific way of worldmaking, which is co-constituted by formal elements such as framing, camerawork, and editing. Second, we address experimental progress. Here we weigh the promises and perils of neuroscientific studies by discussing the motor neuron account to camera movements as an example. Based on the limitations we identify, we advocate for a multi-method study of film experience that brings cognitive science into dialogue with philosophical accounts and qualitative in-depth explorations of subjective experience.
Design of an electronic power transformer

For the distribution of electrical energy in Germany, application-specific transformers with ratings of 110/20 kV, 110/10kV, 40 MVA, 50 Hz are typically in operation. Due to their weight, these transformers can only be transported with great expense (usually by rail). Therefore a considerable number of reserve transformers has to be held in stock in each distribution area, to guarantee power reliability to utility customers by quick replacement. To reduce assets, a universal, mobile and flexible (adjustable to different medium-voltage levels and truck movable) transformer reserve unit is desired by utility companies. The modular design of an electronic power transformer for this purpose is given in this paper. Based on power electronics, additional features like fast voltage regulation, reactive power compensation, ride-through capability etc. are described.
Does It Need to be Broader or Deeper? Trade-Offs in Entrepreneurship Theorizing

Given the importance of theorizing about an entrepreneurial phenomenon, we seek to highlight the common challenges of entrepreneurship papers’ theorizing and offer suggestions for how we (as a community of scholars) can address these challenges to develop more robust and impactful entrepreneurship papers to advance the entrepreneurship field. Specifically, we identify the following major reviewer comments of entrepreneurship papers regarding their scope, common features (i.e., contextualization, boundary conditions, and time considerations), and “point of view”. Elaborating on these common comments of entrepreneurship theory papers, we offer guidance on incorporating these insights when writing or reviewing entrepreneurship papers.
Analysis of Oxygen Saturation Detection Method on Intelligent Mobile Devices

With the fast development of mobile devices and great concern on health surveillance, it is becoming increasingly popular to collect, analyze, and interpret people's health-related data by using intelligent mobile devices in their daily life. Oxygen saturation is an important physiological parameter referring to the concentration of oxygen in the blood, and prolonged low oxygen levels may lead to respiratory or cardiac arrest. Previous oxygen saturation detection methods require infrared light, however most of the off-the-shelf mobile devices lack such infrared light transmitter and receiver modules. This paper presents a novel oxygen saturation estimation method emplying a RGB camera and visible light in most of mobile devices. By applying of traditional optical oxygen saturation estimation model to mobile devices, and analyzing its problem for those devices, this study proposes a new oxygen saturation estimation model on intelligent mobile devices and offers an approach to solve the baseline drift problem in mobile cameras. Experiments demonstrate the effectiveness of the proposed method and its potentials in many oxygen saturation based researches such as daily-activity based healthcare with mobile devices.

Dynamic response analysis of an aircraft structure under thermal-acoustic loads

Future hypersonic aircraft will be exposed to extreme combined environments includes large magnitude thermal and acoustic loads. It presents a significant challenge for the integrity of these vehicles. Thermal-acoustic test is used to test structures for dynamic response and sonic fatigue due to combined loads. In this research, the numerical simulation process for the thermal acoustic test is presented, and the effects of thermal loads on vibro-acoustic response are investigated. To simulate the radiation heating system, Monte Carlo theory and thermal network theory was used to calculate the temperature distribution. Considering the thermal stress, the high temperature modal parameters are obtained with structural finite element methods. Based on acoustic finite element, modal-based vibro-acoustic analysis is carried out to compute structural responses. These researches are very vital to optimum thermal-acoustic test and structure designs for future hypersonic vehicles structure
Creative performance pressure as a
 double‐edged
 sword for creativity: The role of appraisals and resources

Creativity, or the generation of novel and useful ideas or products, is widely viewed as the cornerstone of organizational innovation and success. However, high pressure to be creative may have mixed implications for employee creativity. In this article, we first systematically conceptualize the nature of the concept of creative performance pressure. Next, building on transactional stress theory, we investigate (a) how creative performance pressure influences employee creativity through different appraisals (i.e., challenge and hindrance) and (b) the moderating role of a job and personal resource (i.e., servant leadership and promotion focus) in the stressor appraisal process. In Study 1, we developed a creative performance pressure scale and assessed its psychometric properties across two samples ( N = 181 for Sample 1; N = 253 for Sample 2). In addition, using multi-wave, multi-source data (Study 2), we tested our hypotheses in a Chinese sample ( N = 206). The results demonstrated that creative performance pressure can have both positive and negative effects on employee creativity through challenge and hindrance appraisals, respectively. Servant leadership moderated the effect of creative performance pressure on challenge and hindrance appraisals, by transmitting the beneficial and detrimental effects of creative performance pressure to creativity, respectively. Similarly, promotion focus moderated the relationship between creative performance pressure and hindrance appraisal. We discuss future research directions and offer several practical implications for both organizational leaders and human resource (HR) practitioners.
Effects of Mixed-Gender Competition: Choking under Pressure in a Dynamic Tournament

In sports, there has been a recent and active movement to promote mixed-gender competitions for achieving gender equality in the field. However, the current debate regarding its effects limitedly focuses on balancing the number of opportunities for females and neglects its effect on athlete performance. To address this gap, this study investigated whether and how mixed-gender competitions mitigate gender-specific disadvantages of interim leaders in dynamic tournaments from the perspective of choking under pressure. Using data from 127 international segregated-gender single and mixed-gender pair figure skating competitions organized by the International Staking Union from 1 July 2006 to 30 June 2018, this study showed that female interim leaders in segregated-gender competitions are more likely to make mistakes in task executions under pressure-inducing circumstances than male interim leaders. However, in mixed-gender competitions, all of these gender-specific influences disappear. The findings contribute to the literature on mixed-gender competitions by providing new evidence on the positive impact of them, as well as expanding the literature on the impact of gender on competitive pressure.
What Influences the Willingness of Blacks and African Americans to Enroll in Preclinical Alzheimer’s Disease Biomarker Research? A Qualitative Vignette Analysis

Background: Alzheimer’s disease (AD) begins with an asymptomatic “preclinical” phase, in which abnormal biomarkers indicate risk for developing cognitive impairment. Research is increasingly focused on validating biomarkers to improve reliable diagnosis and timely clinical treatment of AD. Most preclinical biomarker research lacks adequate representation of Black/African American and other racially and ethnically minoritized individuals, limiting the applicability of data to these groups. This may exacerbate existing disparities by hindering diagnosis and treatment among racially and ethnically minoritized individuals. Objective: Understand the factors influencing willingness of Blacks/African Americans to participate in AD biomarker research and identify opportunities to improve enrollment. Methods: We enrolled Blacks/African Americans (N = 145) between 46–85 years of age who had previously participated in AD research. Participants gave open-ended responses to a vignette describing a hypothetical biomarker research study. Using qualitative content analysis, we identified themes that motivated and discouraged enrollment in AD biomarker research. Results: Participant responses were categorized into several themes. Themes motivating participation included a desire to know their biomarker results and to support research. Major themes discouraging participation included concerns about potential negative psychological outcomes to learning one’s increased risk for AD, doubt about the usefulness of testing, and worry about the potential physical harms of testing. Conclusion: Understanding themes motivating and discouraging AD preclinical biomarker research participation may inform research material development, approach to community engagement, and/or trial design to increase enrollment of Blacks/African Americans.
Sanctum : minimal architectural extensions for isolated execution

Intel's Software Guard Extensions (SGX) have captured the attention of security practitioners by promising to secure computation performed on a remote computer where all the privileged software is potentially malicious. Unfortunately, an independent analysis of SGX reveals that it is vulnerable to software attacks, and it can only be used by developers licensed by Intel. Furthermore, significant parts of SGX are undocumented, making it impossible for researchers outside of Intel to reason about some of its security properties. Sanctum offers the same promise as SGX, namely strong provable isolation of software modules running concurrently and sharing resources, but protects against an important class of additional software attacks that infer private information from a program's memory access patterns. Sanctum shuns unnecessary complexity, leading to a simpler security analysis. We follow a principled approach to eliminating entire attack surfaces through isolation, rather than plugging attack-specific privacy leaks. Most of Sanctum's logic is implemented in trusted software, which is easier to analyze than SGX's opaque microcode. Our prototype targets a Rocket RISC-V core, an open implementation that allows any researcher to reason about its security properties. Sanctum's extensions can be adapted to other RISC cores, because we do not change any major CPU building block. Instead, we add hardware at the interfaces between building blocks, without impacting cycle time. Sanctum demonstrates that strong software isolation is achievable with a surprisingly small set of minimally invasive hardware changes, and a very reasonable overhead (assuming a software attack model) that is orders of magnitude less than what is incurred by ORAMenabled processors. Our modifications cause a 2% area increase to the Rocket core. Over a set of benchmarks, Sanctum's worst observed overhead for isolated execution is 15.1% over an idealized insecure baseline, and 2.7% average overhead over a representative insecure baseline.
