In-Memory Set Operations on Memristor Crossbar

Performance degradation and higher power dissipation for data-intensive applications are common in von Neumann computers. This is due to the data transfer between the memory and processor. Non-von Neumann architecture addresses this issue by performing computations within the memory, that is, in-memory computing. The nonvolatile memory can be built using an alternative building block called a memristor. Logical NOT and NOR gates can be realized on memristor crossbars. This allows to perform arithmetic and logic operations within the memory. An architectural support for a constant time in-memory comparison has been introduced. This adds FILL and MCMP instructions to the instruction set. Four basic set operations are implemented using the instruction set. In-memory union, cartesian product, transitive closure, and power set generation achieve an average energy reduction of <inline-formula> <tex-math notation="LaTeX">$168\times $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$249\times $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$134\times $ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$264\times $ </tex-math></inline-formula>, respectively. However, for higher input sizes, central processing unit-based union, cartesian product, and transitive closure perform better by an average of <inline-formula> <tex-math notation="LaTeX">$1.58\times $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$1.23\times $ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$2.07\times $ </tex-math></inline-formula>, respectively. In-memory power set generation achieves an average speed-up of <inline-formula> <tex-math notation="LaTeX">$1.14\times $ </tex-math></inline-formula>.
Using Synthetic Cyclone Models for High Wind GNSS-R Calibration, Validation, and Algorithm Development: A CYGNSS Case Study

This work reports a case study of the use of synthetic cyclone models for the development, assessment and validation of global navigation satellite system reflectometry (GNSS-R) wind speed remote sensing algorithms using a cyclone global navigation satellite system (CYGNSS) data record extending from 1 August 2018 to 31 December 2022. Synthetic cyclone models are shown to be useful in assessing the high wind speed sensitivity of CYGNSS’s v1.0, v2.1, v3.0, v3.1, and future v3.2 normalized bistatic radar cross Section (NBRCS) products due to the extended matchup dataset of high wind speed information that is obtained. The models are also shown useful in investigating the impacts of specific error corrections terms and in the development of level-2 geophysical model functions (GMFs) for the retrieval of ocean surface winds.
Determination of GaAs zinc blende/wurtzite band offsets utilizing GaAs nanowires with an axial GaAsSb insert

By applying a correlated micro-photoluminescence spectroscopy and transmission electron microscopy (TEM) approach, we have utilized molecular beam epitaxy grown self-catalysed GaAs nanowires (NWs) with an axial GaAsSb insert to determine the band offsets at the crystal phase heterojunction between zinc blende (ZB) and wurtzite (WZ) GaAs. Two distinct PL emission bands originating from the ZB GaAsSb insert were identified. The lower energy PL emission allowed an independent verification of the maximum Sb molar fraction to be ∼30%, in agreement with quantitative high-angle annular dark field scanning TEM performed on the same single NW. The higher energy PL emission revealed a low temperature ZB/WZ band offset of 120 meV at the interface between the two GaAs crystal phases occurring at the upper boundary of the insert. Separate conduction and valence band offsets develop at a higher temperature due to the different temperature dependence of the ZB and WZ GaAs band gaps, but both offset values show a relativ.
Charitable giving and intermediation: a principal agent problem with hidden prices

Donations are often made through charitable intermediaries that can fund themselves from these same donations. After intermediation, only a fraction of the amount donated may reach the intended beneficiary. The price of charitable output is therefore higher after intermediation than if donors donated directly toward the end cause. At the same time, this price is hidden from donors since they cannot verify how much intermediaries pass on. We show that while donors reduce their donation in intermediation itself, and also reduce their donation because they expect the price of charitable output to increase, both reactions are either fully or partly compensated by their ethical preferences for the recipient’s rights. Charitable output, therefore, can be a Giffen-good.
Eccentric orbit binary black hole inspirals: Informing the post-Newtonian expansion through black hole perturbation theory

The era of gravitational-wave astronomy has arrived. As a result, we now have the opportunity to observe features of the universe previously hidden from human view. To advance efforts on wave detection, this dissertation presents new results on the dynamics of non-spinning binary black hole (BBH) inspirals. In it I focus on the eccentric-orbit extreme-mass-ratio inspiral (EMRI), a presently underdeveloped class of BBHs in which the orbit has an elliptical shape and one of the two masses is much larger than the other. I investigate these EMRIs by combining two common approaches --- the small-mass-ratio approximation of black hole perturbation theory (BHPT) and the small-velocity approximation of post-Newtonian (PN) theory --- in novel ways to better describe their evolution. BHPT is studied using the Mano-Suzuki-Takasugi formalism to represent first-order perturbations as infinite summations of hypergeometric functions. These solutions are then analyzed in the slow-motion regime to derive high-order PN series for observable quantities, with particular focus on the fluxes: the total energy and angular momentum radiated by the system. BHPT-PN expansions for the fluxes at infinity are found separately using numerical and analytical approaches to compare efficacy. The result is the derivation of flux terms to at least $e^{20}$ through 10PN and at least $e^{10}$ through 19PN. Results to 10PN/$e^{20}$ and 18PN/$e^{10}$ are similarly found for the fluxes at the central horizon. Simultaneously, the fluxes at infinity are studied within PN theory using the multipolar post-Minkowskian PN formalism. By manipulating certain multipole moments in Fourier space, we find infinite sets of previously unknown multipole contributions. Compact forms are derived for the leading logarithm flux terms and their 1PN corrections. Drastic simplifications are made to the subleading logarithms and their 1PN corrections. Compact expressions are extracted for the full 4PN and 6PN Log fluxes at lowest order in the mass ratio. Finally, similar analytical techniques are applied to derive novel BHPT-PN expansions for two local conserved quantities: the generalized redshift invariant and spin-precession invariant. The former is found to 8.5PN and $e^{20}$ and the latter to 6.5PN and $e^{16}$. Overall, this thesis offers a deeper understanding of the gravitational radiation and orbital motion of EMRIs and finds new structure in the BHPT and PN formalisms as a whole. The results contained herein will contribute to the analysis of waveform data obtained by LISA, the space-based gravitational-wave detector scheduled for launch in 2034.
A fast second-order parareal solver for fractional optimal control problems

The gradient projection technique has recently been used to solve the optimal control problems governed by a fractional diffusion equation. It lies in repeatedly solving the state and co-state equations derived from the optimality conditions, and the Crank–Nicolson (CN) scheme, which gives a second-order numerical solution, is a widely used method to solve these two equations. The goal of this paper is to implement the CN scheme in a parallel-in-time manner in the framework of the parareal algorithm. Because of the stiffness of the approximation matrix of the fractional operator, direct use of the CN scheme results in a convergence factor ρ satisfying ρ → 1 as Δ x → 0 for the parareal algorithm, where Δ x denotes the space step-size. Here, we provide a new idea to let the parareal algorithm use the CN scheme as the basic component possessing a constant convergence factor ρ ≈ 1 / 5 , which is independent of Δ x . Numerical results are provided to show the efficiency of the proposed algorithm.
GSSC: Graph Summarization based on both Structure and Concepts

In this paper, we propose a new method for graph summarization named GSSC, Graph Summarization based on both Structure and Concepts. In this method, an attributed graph is summarized by considering both of its topology and related concepts. In this method, for a given attributed graph a new graph is constructed that an edge in this new graph represents structural and conceptual similarity of its two end points. Structural and conceptual similarity of two nodes not necessarily has the equal amount of importance in the weight of the resulting edge. For example, for a special case such as query answering, structure can be more important and vice versa. Similarity of two nodes is computed based on Jaccard similarity. This method has some advantages such as flexibility, simplicity, learning capability, user-orientation that makes it a better method for graph summarization. We implemented our method and the method proposed by Bei and evaluated these two methods on real-life dataset HEP_TH. Our experimental results showed effectiveness and efficiency of our proposed method.
A New Existence Result of Equilibria for Vector Equilibrium Problems

Abstract In this paper, we deal with vector equilibrium problems. We prove the nonemptiness of the solution set for this type of problems in the sequential compactness case and in the absence of convexity and lower semicontinuity assumptions. Some examples are presented and an existence result for countable systems of vector equilibrium problems is stated.
Fully implicit method for coupling multiblock meshes with nonmatching interface grids

ABSTRACT A newly developed efficient and fully implicit method for multiblock mesh coupling that preserves the convergence characteristics of single-block meshing is presented. The technique is developed in the context of an unstructured pressure-based collocated finite-volume method, is applicable to both segregated and coupled flow solvers, and is ideal for code parallelization. The discretization at interfaces is performed in a separate step to stitch the regions sub-matrices into a global matrix. By solving the global matrix, the solution achieved to the multiregion problem is exactly the one that would result from a single-mesh discretization. The method is tested by solving three laminar flow problems. Solutions are obtained by meshing the domain as one block or by subdividing it into a number of blocks with non-matching grids at interfaces. Results show the very tight coupling at interfaces with a convergence rate that is independent of the number of blocks used.
Disparities of Self-compassion and Job Satisfaction across Decision-Making Styles among Filipino Workers

Self-compassion and job satisfaction of Filipino workers across their decision-making styles are constructs of the present study being presented in the field of work. This paper aimed to identify the decision-making style; describe and measure the degree of self-compassion and job satisfaction; and determine the difference in self-compassion and job satisfaction across decision-making styles among respondents. The General Decision-making Styles Questionnaire (GDSQ), Self-compassion Scale, and Job Satisfaction Survey were administered to 359 respondents who aged from 28-60 years old, regardless of gender, across different companies in Calabarzon. The respondents were employees from entry level positions, supervisors, as well as executive level positions. Results have shown that rational, intuitive, dependent, avoidant, spontaneous, and dependent were the decision-making styles among respondents. The degree of self-compassion was at a high level (M=142.78, SD=21.16), while the degree of job satisfaction showed respondents’ ambivalence towards their job (M=3.51, SD=0.46). The Multivariate Analysis of Variance (MANOVA) confirmed a significant difference (Fobt= 5.054**, p of 0.0001) in the self-compassion and job satisfaction across decision-making styles among Filipino workers and was validated by Fisher’s LSD as a post hoc test. Outcomes of the study is recommended as a basis in proposing intervention programs in human resource management and industrial psychology. Mixed-method research is recommended to strengthen the concepts of self-compassion and related variables in this study.

Rational design of novel compounds to serve as potential NDM-1 inhibitors using molecular docking, molecular dynamics simulation, and physicochemical studies

ABSTRACT New Delhi Metallo-β-lactamase (NDM-1) is an enzyme that hydrolyses a wide range of β-lactam antibiotics, including most carbapenems, leading to antimicrobial resistance. The development of a novel NDM-1 inhibitor for use in combination with carbapenems may help to combat drug-resistant pathogens. Twenty compounds were designed based on the structural features of the NDM-1 active site to inhibit bacterial NDM-1 and protect β-lactam antibiotics from enzyme attack. The designed molecules were naphthalene, thiazole, and sulfone derivatives because they could coordinate with the zinc ions and form hydrophobic contracts with the enzyme’s active site. A molecular docking protocol was used to identify potential inhibitor(s) of the NDM-1 target protein. Furthermore, drug-likeness and pharmacokinetic properties of the designed molecules were predicted. Three compounds with the more negative ΔGbinding results were selected for further investigation using molecular dynamic (MD) simulations. T016 had a significantly more negative binding free energy than the positive control and other designed molecules, had stable MD simulations (Root-mean-square deviation < 0.5 Å), passed Lipinski’s rule of five, and had favourable physicochemical and pharmacokinetic properties. The findings can be used to inform the synthesis and in vitro testing of the selected molecules.
Youth Knowledge on the Utilization of Edible Insects as Food and Feed

The utilization of edible insects as food and feed is not a new concept, it is a practice that has been part of the tradition of many communities around the world. They have been primarily used as supplementary food in most African countries. However, there has been a significant decline in the consumption of insects over the years, especially among young people. Therefore, this study aimed to investigate the knowledge on entomophagy and the utilization of insects among the youth. The study revealed that the majority of youth had limited knowledge about consumption, nutrition, harvesting, preparation and use of edible insects as livestock feed. From the Chi-square analysis it was observed that age and education level have a significant relationship to the familiarity of consumption of edible insects, P=0.014 and P=0.009 respectively. The results also show that there is a significant association between awareness on the nutritional value of insects with age and education level, P=0.001 and P=0.009 respectively. Logistic regression analysis was used to find the association between demographic characteristics, knowledge and the utilization of edible insects. The results revealed that education level, age and knowledge have an impact on the utilization of edible insects. Lack of knowledge contribute to the unwillingness of youth to consume insects. It is noticeable that indigenous knowledge on entomophagy is slowly disappearing with the shift in eating habits and changes in the socio-economic environments. As such, it is imperative that indigenous knowledge is preserved and educational interventions are done to raise awareness on the benefits of entomophagy in order to improve the utilization of insects among the youth.
A Switched-Capacitor-Based 7-Level Self-Balancing High-Gain Inverter Employing a Single DC Source

This paper discloses a novel switched capacitor (SC)-based 7-level inverter with a single DC source. The proposed inverter has the ability to self-balancing the voltage of the capacitor without using a closed-loop voltage balancing circuit. Two capacitors are equally charged by the input source owing to the series-parallel charging and discharging continuously in a full cycle. The proposed 7-level SC inverter requires less number of switches, driver diodes, and capacitors and a lower number of semiconductor switches than most recently developed topologies. Furthermore, four out of the eight switches operate at the fundamental frequency, which simplifies the control scheme. A fundamental frequency switching scheme is used to control the output of the inverter. The self-balancing and voltage-boosting features of the proposed structure are validated on MATLAB/software platform and verified experimentally.
500‐Year Periodic Vegetation and Monsoonal Climate Oscillations During the Last Deglaciation in East Asia

Fluctuations in monsoonal climate on orbital‐ to millennial‐timescales have had a major impact on vegetation change in East Asia since the last deglaciation. However, the influence of centennial‐scale oscillations on the spatio‐temporal characteristics of vegetation and climate during the last deglaciation remains controversial. We present a well‐dated, decadal‐resolution pollen record from the sediments of annually laminated Lake Xiaolongwan in Northeast Asia, which reveals major orbital‐/millennial‐scale and minor quasi‐periodic, that is, ∼500‐year (yr) cyclic, vegetation changes from ∼19.96 to ∼10.79 Kyr ago (covering the last deglaciation). The ∼500‐yr cycles are characterized by alternations in broadleaved forest/boreal coniferous forest with tundra steppe representing warm and humid/cold and dry phases of the monsoonal climate. This cyclicity may be related to El Niño‐like/La Niña‐like state and low‐latitude atmosphere‐ocean processes, against the background of the long‐term trend of the deglacial climatic evolution. Our findings demonstrate a close relationship between ecosystem succession and climate change on centennial scale.
Diagnosis and Management of Aortic Dissection in a Pediatric Patient With Turner Syndrome: A Simulation

Aortic dissection is exceedingly rare in the pediatric population. However, it is much more common among children and adolescents with certain underlying syndromes, including Turner syndrome. Furthermore, aortic dissection carries significant mortality without prompt diagnosis and management. Therefore, pediatric emergency providers should know how to recognize and treat pediatric aortic dissection in a patient with Turner syndrome. We designed this simulation for pediatric emergency medicine fellows. A simulated adolescent female patient with a known history of Turner syndrome presents with chest pain, tachycardia, and hypertension. Participants must order and interpret the appropriate diagnostics, diagnose aortic dissection, and manage aortic dissection adequately. This simulation was completed by six pediatric emergency medicine fellows and one pediatric resident. After completing the simulation, six participants (85.7%) provided anonymous feedback on a five-point Likert scale (one = strongly disagree, five = strongly agree). Feedback was positive, and participants agreed that the case content was relevant to their clinical practice and that the event will improve their clinical practice. This simulation encourages participants to recognize and manage pediatric aortic dissection in patients with Turner syndrome. Participants felt that the simulation was relevant and will improve their clinical practice.
Mirror symmetry breaking in liquids and liquid crystals

ABSTRACT In the recent two decades liquid crystal science has contributed significantly to the understanding of mirror symmetry breaking and spontaneous emergence of chirality in fluids. This account tries to summarise the current state of understanding of mirror symmetry breaking in the liquid and liquid crystalline mesophases, ranging from isotropic liquids, via cubic, columnar and tetragonal SmQ phases of polycatenar compounds, the twist bend nematic phases of bent dimesogens to the heliconical and conglomerate type smectic phases of bent-core mesogens. Especially, the importance of dynamic chirality synchronisation of molecular conformers, cooperativity, helical superstructures, layer chirality, network formation, as well as chiral and achiral surface effects is discussed. At the end the transition from local to absolute symmetry breaking, chirality amplification and the relevance for the emergence of uniform chirality in prebiotic fluids and biosystems are considered.

A T-Type DAB-Based Isolated DC-DC-AC Three-Port Converter With High Power Efficiency

This article proposes a high-efficiency isolated dc–dc–ac three-port converter (TPC) intended for residential photovoltaic-battery systems. The TPC is derived from a dual active bridge based dc–ac converter. Its dc-side provides two bidirectional dc ports by sharing the full-bridge topology, while its ac-side enables direct ac-load connection via a unique T-type half-bridge structure. Due to the shared branches and T-type topology, the proposed TPC has few components but offers single-stage power conversion and substantial control degrees of freedom (CDFs). Sufficient CDFs facilitate the TPC to maintain high efficiency when performing decoupled power flow control among the three ports. To maximize the benefits of sufficient CDFs, a pulsewidth modulation (PWM) plus triple-phase-shift (TPS) modulation scheme based on these CDFs is presented. PWM is employed to control the dc–dc power flow while TPS is used to regulate the dc–ac power flow. Benefiting from the TPS optimization, this TPC features low rms current and excellent soft-switching performance. Compared to state-of-the-art, the efficiency of the proposed TPC is improved by up to 1% under the proposed modulation scheme. The effectiveness of the proposed TPC is verified by a 220-V 500-W experimental setup.
On local operations that preserve symmetries and on preserving polyhedrality of maps

We prove that local operations that preserve all symmetries, as e.g. dual, truncation, medial, or join, as well as local operations that are only guaranteed to preserve all orientation-preserving symmetries, as e.g. gyro or snub, preserve the polyhedrality of simple maps. This generalizes a result by Mohar proving this for the operation dual. We give the proof based on an abstract characterization of these operations, prove that the operations are well defined, and also demonstrate the close connection between these operations and Delaney-Dress symbols.
