subject: Homestead food garden programme

description: Pumpkin is a source of protein and fat and is a product of homestead gardens. The homestead food garden programme was established in 1997 as one of the projects identified by the government of South Africa to alleviate hunger, malnutrition, and food insecurity in vulnerable households. The objective of this study was to identify the challenges and opportunities of establishing pumpkin production within the homestead food garden programme of Gauteng Province, South Africa. The study used a structured questionnaire to collect primary data from 500 pumpkin producing households. Respondents included participants and non-participants in the food garden programme. The results showed that respondents participating in the food garden programme had a lower educational status than non-participants. High water costs, water shortages, lack of agricultural land and inadequate production inputs were identified as the main challenges for establishing adequate homestead pumpkin production. It is recommended that programme implementers and policy makers should encourage more women to participate in the programme, to factors that hindered the establishment of homestead food gardens. The provision of additional extension service could assist these challenges.

description: In this study, a series of Mg-modified γ-Al2O3 sorbents have been introduced to simultaneously remove HCl and HF in a low-temperature environment. These sorbents were prepared by impregnation, and the effects of Mg loading amount and calcination temperature on the performance of the sorbent were investigated. The optimal sorbent (modified by 15 wt% Mg and calcined at 400℃, Mg15/Al2O3-400) exhibited the highest adsorption capacity of all the sorbents tested, 37.89 mg(HF)•gsorbent−1 and 34.54 mg(HCl)•gsorbent−1, respectively. Taking into account an excellent HF(HCl) capacity of the Mg15/Al2O3-400, these sorbents are very promising HF(HCl)sorbents usable in a low-temperature environment. The role of MgO loaded on γ-Al2O3 was investigated by Brunauer−Emmet−Teller (BET) method, X-ray diffractometer (XRD), scanning electron microscopy (SEM-EDS), X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of CO2 (CO2-TPD), and thermogravimetric analysis (TG-DTG). The results revealed that MgO acted as a ‘leading role’ to promote the adsorption activity of the sorbents. BET analysis demonstrated that the Mg modification process did not seriously change the pore type of the γ-Al2O3. CO2-TPD results revealed that the calcination temperature will significantly affect the number and strength of the basic sites on the surface of the sorbent. In addition, XRD and XPS analysis indicated that the consumption of MgO and the accumulation of reaction products on the surface and pores are the main reasons for the deactivation of the sorbent.

description: We explore some properties of twin kilohertz quasiperiodic oscillations (QPOs) in a simple toy-model consisting of two oscillation modes coupled by a general nonlinear force. We examine resonant effects by slowly varying the values of the tunable, and nearly commensurable, eigenfrequencies. The behavior of the actual oscillation frequencies and amplitudes during a slow transition through the 3:2 resonance is examined in detail and it is shown that both are significantly affected by the nonlinearities in the governing equations. In particular, the amplitudes of oscillations reflect a resonant exchange of energy between the modes, as a result the initially weaker mode may become dominant after the transition. We note that a qualitatively similar behavior has been recently reported in several neutron star sources by Torok (2008, arXiv:0812.4751), who found that the difference of amplitudes in neutron star twin peak QPOs changes sign as the observed frequency ratio of the QPOs passes through the value 3:2.

description: Nearly all major astronomy observatories maintain telescope and staff bibliographies. Bibliographies are one of many tools used by observatory management to evaluate their organizations’ research productivity. In most cases observatory libraries play a crucial role in the data collection and metric analyses that drive critical decisions related to benchmarking, funding, mission evaluation, hiring, talent retention, and promotion. It is incumbent on the observatory’s leadership, instrument scientists, and bibliographers together to ask the right questions in order to understand what they’re trying to measure, whether it is possible and fair to assess, and the association between output and impact. Over time, astronomy librarians have not only enhanced their bibliography databases and set new parameters and guidelines to ensure equity, such as the FAIR principles and a push for open access publishing; they have also collaborated with fellow librarians, archive scientists, astronomers, and publishers around the globe to exchange best practices and to understand how astronomy as a science is changing. In this presentation, we will provide an overview of the ESO and Hubble bibliographies. We will inspect what constitutes impact, and how institutional and individual staff metrics can be assessed to capture the full range of contributions to the advancement of science during all career stages and over the lifetime of an observatory and its data archive.

description: We present AVOCADO (AdaptiVe Optimal Collision Avoidance Driven by Opinion), a novel navigation approach to address holonomic robot collision avoidance when the robot does not know how cooperative the other agents in the environment are. AVOCADO departs from a Velocity Obstacle's (VO) formulation akin to the Optimal Reciprocal Collision Avoidance method. However, instead of assuming reciprocity, it poses an adaptive control problem to adapt to the cooperation level of other robots and agents in real time. This is achieved through a novel nonlinear opinion dynamics design that relies solely on sensor observations. As a by-product, we leverage tools from the opinion dynamics formulation to naturally avoid the deadlocks in geometrically symmetric scenarios that typically suffer VO-based planners. Extensive numerical simulations show that AVOCADO surpasses existing motion planners in mixed cooperative/non-cooperative navigation environments in terms of success rate, time to goal and computational time. In addition, we conduct multiple real experiments that verify that AVOCADO is able to avoid collisions in environments crowded with other robots and humans.

description: The Incomplete Preferences Proposal (IPP) is an idea for ensuring that advanced artificial agents never resist shutdown. A key part of the IPP is using a novel `Discounted Reward for Same-Length Trajectories (DReST)' reward function to train agents to (1) pursue goals effectively conditional on each trajectory-length (be `USEFUL'), and (2) choose stochastically between different trajectory-lengths (be `NEUTRAL' about trajectory-lengths). In this paper, we propose evaluation metrics for USEFULNESS and NEUTRALITY. We use a DReST reward function to train simple agents to navigate gridworlds, and we find that these agents learn to be USEFUL and NEUTRAL. Our results thus provide some initial evidence that DReST reward functions could train advanced agents to be USEFUL and NEUTRAL. Our theoretical work suggests that these agents would be useful and shutdownable.
DORA and Responsible research assessment: rethinking what we value in research

description: The San Francisco Declaration on Research Assessment (DORA) is a campaigning initiative to improve the ways that we evaluate research and researchers. It aims particularly to help people understand the problems associated with over-reliance on aggregate metrics like the journal impact factor or H-index in assessment processes. Such metrics have enduring appeal because they appear to offer the simplicity and objectivity of numerical analyses. However, we need to be mindful of the subjective nature of decisions that lead to citation counts – the raw material of many performance metrics – and the biases that perturb them. The challenge now, if we are to move to more robust forms of evaluation, is to ensure that these are as effective and as efficient as possible. Embracing this challenge will also help to clear the way for more open and impactful science, and for a more inclusive academy.

description: We compute the entropy of antiferromagnetic quantum spin-s chains in an external magnetic field using exact diagonalization and Quantum Monte Carlo simulations. The magnetocaloric effect, i.e., temperature variations during adiabatic field changes, can be derived from the isentropes. First, we focus on the example of the spin-s=1 chain and show that one can cool by closing the Haldane gap with a magnetic field. We then move to quantum spin-s chains and demonstrate linear scaling with $s$ close to the saturation field. In passing, we propose a new method to compute many low-lying excited states using the Lanczos recursion.

description: Astronomy is a far-reaching field, with the marvels of space inspiring people of all ages all across the world. While an interest in astronomy is present across all groups of people, this is not represented on a professional level, with representation from minority groups dwindling the further up the career path you go. Improving diversity within fields and institutions has been shown to have positive effects (Nielsen et al. 2018, Nature Hum Behav 2, 726-734) and as such when looking to the future of astronomy it is in the field's benefit to discuss what we can do. In this talk, on behalf of the organisation IDEEA (Inclusion, Diversity and Equity in European Astronomy), I will discuss the current state of diversity in our field and how changes to hiring practices and other actions can assist with improving diversity in astronomy in the future.

description: We calculate Wilson loops of various sizes up to loop order $n=20$ for lattice sizes of $L^4 (L=4, 6, 8, 12)$ using the technique of Numerical Stochastic Perturbation Theory in quenched QCD. This allows to investigate the behaviour of the perturbative series at high orders. We discuss three models to estimate the perturbative series: a renormalon inspired fit, a heuristic fit based on an assumed power-law singularity and boosted perturbation theory. We have found differences in the behavior of the perturbative series for smaller and larger Wilson loops at moderate $n$. A factorial growth of the coefficients could not be confirmed up to $n=20$. From Monte Carlo measured plaquette data and our perturbative result we estimate a value of the gluon condensate $$.

Ellipsometric investigation of the mechanism of hologram storage in lithium niobate

Publisher: name: University of British Columbia
Year: 2011

description: A computer-controlled ellipsometer was used to obtain data on the birefringence changes induced in lithium niobate crystals by irradiation with an argon-ion laser. The instrument was set to take readings on a rectangular grid of points before and after irradiation. Irradiation was performed with circular and with narrow rectangular light beams. Results are compared with the prediction of the model of Chen in which he postulated the presence of an internal field Eo in the direction of the c-axis of the crystal. According to his theory, electrons, photoexcited from traps by the laser light, drift under the influence of Eo along the c-axis before being retrapped. The resulting space-charge field set between positive ionised centres and trapped electrons gives rise to the observed birefringence changes via the linear electro-optic effect of the crystal. Approximate mathematical models based on Chen's theory are used to solve the problem with narrow rectangular light beams. Results are compared with experiments.

description: The Agricultural Knowledge and Innovation System (AKIS) is a concept that describes the different organisations and individuals involved in the process of innovation adoption and their links. Organisations are seen as the traditional source of advice, and historically, this was led by government institutions. In developed economies, disengagement of government in terms of information and advice provision has led to a rise in the privatisation of the service leading to a complex set of interrelationships. The aim of this project was to provide recommendations for improving the performance and effectiveness of advisory services in strengthening the knowledge flows between science, in its widest context and practice, and the farming community, and with particular emphasis on the needs of the farmer. This was achieved via consultation with the farming community through a series of sector-specific focus groups and a subsequent questionnaire survey. The study found that farmers make decisions on the basis of a continuum of awareness creation through careful consideration and onto adoption/implementation. The types of information that farmers are looking for relate to three areas: business, operational, and compliance. The best way to facilitate the flow of information is through a farmerâ€™s professional and social networks.

DIAGNOSIS
Chilo suppressalis, also known as the Asiatic Rice Borer or Striped Rice Borer, is recognized by the cream/yellow forewing with a conspicuous black rounded discoidal spot in males, while females are similar to those of C. sacchariphagus. Chilo suppressalis can be separated from other Chilo species by the following characters of the male genitalia (Fig. 100): arms of juxta ca 2/3 of valva length, distincly swollen at midlength; phallus with characteristic long, thin ventral arm (Bleszynski, 1970c). In female genitalia (Fig. 158), the following characters separate this species: ostial pouch small, slightly demarcated from ductus bursae; ductus bursae basally forming a twist, with sclerotized band; corpus bursae with elongate signum (Bleszynski, 1970c).
DISTRIBUTION
EAST AND SOUTH AFRICA; BANGLADESH; BRUNEI; CAMDOBIA; CHINA; INDIA; INDONESIA; IRAN; JAPAN; LAOS; MALAYSIA; PAKISTAN; PHILIPPINES: Luzon (Bataan, Batangas, Cagayan, Ifugao, Laguna, Nueva Ecija, Pangasinan, Mountain Province), Marinduque, Mindanao (Misamis Oriental, South Cotabato); SRI LANKA; TAIWAN; THAILAND; VIETNAM.
DNA BARCODING
A maximum intraspecific p-distance of 0.3% is observed between MFNLEP-PYRALPHIL11-A02 from Luzon (Ifugao) and the other three specimens from Luzon and Marinduque. Haplotype network reconstruction reveals that the Philippine haplotype is shared with specimens from China, South Korea, and Iran.
REMARKS
Chilo suppressalis is one of the most severe rice pest species and is present in the whole Oriental region, reaching temperate China and Japan to the North. It has been introduced to Europe and Hawaii (Maes, 2022). Chilo suppressalis together with Scirpophaga incertulas (Walker, 1863) are the most widespread rice pest species in the Philippines (Calora & Reyes, 1972). The observed decline of Chilo suppressalis in the past decades could be due to the introduction of narrow-stemmed rice (Litsinger et al., 2011).

description: The global agri-food industry is facing a number of strategic challenges, which demand that continual strategic adjustments and changes be made in companies. Driven, in particular, by globalisation, increasing international competition and technological developments, the industry must continually develop in order to maintain and improve long-term international competitiveness. Business models, methods and approaches have been developed to identify strategic problems and solutions for the industry. The aim of this paper is to analyse how selected agri-food companies recognized and have tackled the challenges, and what lessons can be learned. Four agri-food companies or industries with international dimensions and significance are analysed. All companies have been influenced by globalisation, liberalisation and increasing international competition. The article illustrates how changing competitive conditions made some the companies choose similar solutions, while they made others choose different solutions â€“ connected to strategic business models. Some of the companies focused on cost competitiveness through reallocation and structural development, while others chose to optimise their competencies through vertical integration, cooperation and global strategic alliances. Another company could, through innovation, move into a blue ocean. The creation of unique products and new markets resulted in brand new competitive parameters. Finally, the last company could generate the necessary growth through collaboration with institutional investors as well as through investments abroad. A focus on the core business was maintained as a strategic choice, and the strategic development was anchored in the entire organisation.

description: In this work, we calculate the form factors for $J/ψ\to \bar{D}^{(*)0}$ induced by the flavor changing neutral currents (FCNC) in terms of the QCD sum rules. Making use of these form factors, we further calculate the branching fractions of semileptonic decays $J/ψ\to \bar{D}^{(*)0} l ^+ l^-$ ($l=e, μ$). In particular, we formulate the matrix element $$ with $T_{μν}$ being a tensor current, which was not fully discussed in previous literature. Our analysis indicates that if only the standard model (SM) applies, the production of single charmed mesons at the present electron-positron colliders is too small to be observed even the resonance effects are included, therefore if an anomalous production rates are observed, it would be a hint of new physics beyond SM. Even though the predicted branching ratios are beyond the reach of present facilities which can be seen from a rough order estimate, the more accurate formulation of the three point correlation function derived in this work has theoretical significance and the technique can also be applied to other places. In analog to some complicated theoretical derivations which do not have immediate phenomenological application yet, if the future experiments can provide sufficient luminosity and accuracy, the results would be helpful.

description: Agricultural cooperatives in the Western world have proven to be efficient in many cases. Therefore, it is likely that other countries with a less developed agricultural industry can learn from the experiences, both good and bad, of Western countries. A number of drivers behind the formation and development of cooperatives which are significant for the spreading and transfer of cooperative ownership can be identified. Agriculture and the food industry have several chronic challenges, but cooperative ownership can, to a large extent, solve these problems, while at the same time industrial and socio-economic benefits can, potentially, be achieved. Based on these factors and assessments and input from stakeholders in countries planning a stronger agricultural cooperative industry, a number of opportunities and barriers have been identified with regard to the transfer of cooperative ownership in agriculture. To a certain extent, experience from cooperative companies in the Western world can be applied to the rest of the world. However, the cooperative model must be adapted to the specific situation in each country. It is rarely possible to transfer experience directly from, for example, Danish cooperatives to countries with a less developed cooperative industry. There are also often a number of economic, cultural, and organisational barriers that need to be overcome.

modal modeling in astrophysics

description: Astrophysics, intended in a broad sense as including both the physics of the solar system and the physics at large and very large scales (i.e., cosmology), notoriously deals with phenomena and processes taking place in extreme conditions, hardly reproducible in a laboratory. Hence, the adoption of models and computer simulations becomes essential in this field, offering a wide range of exemplary case studies for analyzing the role of models in scientific practices.
 Here, within the framework of the debate on modal modeling in science, we investigate the modalities implied in astrophysical modeling practices by taking into account different levels of abstraction or generality at which phenomena can be framed. To this aim, we analyze two case studies involving modeling gravity at very different regimes: namely, gravity at the solar system level and gravity at cosmological scales. In particular, on the background of the how-possibly/ how-actually ditinction, we investigate how the degree of possibility is related to the level of generality at wich a phenomenon can be framed.
 At first glance, modeling practices and the corresponding implied modalities could appear significantly different when considering different gravitational regimes. On the contrary, by framing the analysis in terms of the how-possibly/how-actually distinction we show that, in both cases, we can identify a web of nested modalities arranged across different levels, and we argue that, independently from the regime, there is no direct link between the degree of possibility and the level of detail at which the phenomena are considered.

description: Improving pasture utilisation on Tasmanian dairy farms is a key focus of research, development and extension programs, through increasing farmer awareness, knowledge and use of best practice pasture management practices. Recommended practices include using pasture management tools to provide objective information about pasture quantity, increasing control, flexibility and accuracy around pasture management decisions. A survey of 162 Tasmanian dairy farmers found large variation in tool use, and investigated the relationship between current tool use and key grazing management decisions. Key decisions include assessing pasture quantity (pre-grazing cover), grazing intensity (post-grazing residual), determining rotation length, and determining the level of non-pasture, supplementary feed required. There was a significant relationship between currently measuring pasture and using that information to assess pre and post-grazing cover, and decisions on rotation length (P<0.05). The relationship between currently measuring pasture and using that information to make decisions on supplement feeding was not significant. Using pasture measurement data can assist in increased accuracy in supplement allocation, with inaccurate allocation resulting in potential over-feeding, substitution of supplement for pasture, reduced pasture regrowth, quality and utilisation. Extension can increase farmer knowledge and understanding of how pasture measurement data can be used to make more informed grazing decisions, and subsequent increase pasture utilization, milk production and farm profitability.

description: We present an effective Lagrangian for low-scale technicolor. It describes the interactions at energies near the mass of the lowest-lying bound states of the lightest technifermion doublet -- the spin-one $ρ_T,ω_T, a_T, f_T$ and the corresponding technipions $π_T$. This Lagrangian is intended to put on firmer ground the technicolor straw-man phenomenology used for collider searches of low-scale technicolor. The technivectors are described using the hidden local symmetry (HLS) formalism of Bando et al. The Lagrangian is based on $SU(2)\otimes U(1)\otimes U(2)_L \otimes U(2)_R$, where $SU(2)\otimes U(1)$ is the electroweak gauge group and $U(2)_L \otimes U(2)_R$ is the HLS gauge group. Special attention is paid to the higher-derivative standard HLS and Wess-Zumino-Witten interactions needed to describe radiative and other decays of the $a_T$ and $ρ_T/ω_T$, respectively.

description: Background: Increased impulsivity is considered to be a core characteristic of borderline personality disorder (BPD) and has been shown to play a significant role in decision making and planning. Neuropsychological studies in BPD revealed impairments of executive functions, and it is assumed that these deficits are related to altered feedback processing. However, research on executive functions in BPD is still limited and the underlying deficits remain an open question. The present study, therefore, explored whether decision-making deficits are related to altered feedback evaluation in BPD.; Method: A total of 18 BPD patients and 18 matched healthy controls underwent a modified version of the Iowa Gambling Task while an electroencephalogram was recorded. Feedback processing was examined by measuring the feedback-related negativity (FRN) and the P300 as electrophysiological correlates of feedback evaluation.; Results: Behavioural results revealed that BPD patients, relative to controls, made more risky choices and did not improve their performance. With regard to the FRN, amplitudes in BPD patients did not discriminate between positive and negative feedback information. Further, BPD patients showed reduced FRN amplitudes, which were associated with enhanced impulsivity and enhanced risk taking. In contrast, the P300 amplitudes following negative feedback were increased in BPD patients, relative to controls.; Conclusions: This study indicates that BPD patients are impaired in decision making, which might be related to a dysfunctional use of feedback information. Specifically, BPD patients did not learn to avoid disadvantageous selections, even though they attended to negative consequences.

description: En el Perú, el 2021 se ha caracterizado por una presencia significativa de inestabilidad política; principalmente, por la lucha mediática y pretenciosa que emprendió la candidata de ultraderecha, Keiko Fujimori, por asumir el poder y negar cualquier medio legítimo que optara el actual presidente de la República, Pedro Castillo. A ello, se le añadió el impacto negativo que dejó la pandemia del COVID-19 en los distintos ámbitos; en especial, en el económico. En ese contexto, la entrevista hecha al inversionista Julio César Galarreta Koicheoski busca dilucidar aquellos medios alternativos, legales y eficaces que existen para que los ciudadanos no resulten afectados. Una de sus alternativas consiste en el negocio que él está desarrollando con respecto a los préstamos que se realizan en las casas de empeño, sin que para ello se asuman riesgos mayores. Esta modalidad es muy diferente de la que emplean los bancos, las financieras, las cajas o las cooperativas de ahorro y crédito, puesto que sus clientes no requieren un historial crediticio favorable, como el de figurar en Infocorp con una calificación indeseable o el de tener préstamos impagados. Más bien, necesitan contar con un artículo que posea un valor dentro del mercado contemporáneo. La valuación, la cotización y los intereses del mismo se producirán a partir de esa lógica, con la finalidad de que exista un beneficio mutuo entre el cliente y la casa de empeño. La dinámica económica que oscila en esta conversación resulta neurálgica, merced a que brinda al lector una información que le permitirá conocer los medios a los que puede acceder para obtener un préstamo en caso de que tenga dificultades al solicitarlo en las formas tradicionales.

description: As the power source of modern society, petroleum and related products are playing important role in chemistry and environment. Basically, light aromatics and C6 paraffines are crucial parts of petrochemical industry. Effective and economic separation of those hydrocarbons from the mixture of isomers or homologous series remains a difficult problem for oil company. Metal organic frameworks (MOFs) or coordination polymers (CPs) would be the potential candidate to this problem due to the porosity and stability. In this work, a novel flexible dual-ligand MOF, Zn-atz-bpda was synthesized and it exhibits very interesting adsorption behavior toward hydrocarbons. The framework can be very easily made by solvothermal reaction of aminotriazole ligand and dicarboxylate ligand with zinc ions. Introducing of triazole ligands enhance the stability and certainty of the MOF. Single crystal XRD unveiled the pillared-layered structure and the distorted aromatic rings might be crucial for the flexibility of Zn-atz-bpda. The structure of Zn-atz-bpda remained robust in organic solvent and acidic solutions and it displayed interesting adsorption properties to aromatic and C6 hydrocarbons. The mechanism and flexibility of it might be a new strategy for designing MOFs with higher performance.
Empowerment in the playground: planning for inclusive interaction and barrier elimination for children with Down Syndrome

description: This thesis was inspired by a playful childlike imagination as well as the desire to provide enjoyment for children of all abilities in outdoor recreational settings.Playgrounds are places where children have the opportunity to explore their capabilities, challenge themselves, and form relationships with others. Whether through physical or social interactions, all children deserve to create fun memories and explore the dimensions of play that provide benefits to both the mind and body.The goal of this thesis was to plan for inclusive interaction and barrier elimination for children with Down Syndrome. The notion of free and fearless fun was created to embody the experience of children playing in a space without judgement, fear, or prejudice from peers. Children are all unique and should be provided the tools to aid in their social experience with others.To get a nuanced perspective on how to create inclusion in all populations, this project included interviews with designers, landscape architects, occupational therapists, and playground specialists. Along with these interviews, surveys and conversations with parents were also conducted to obtain the perspective of the parents’ concerns. These concerns aided in the recommendations of six inclusion solutions. The solutions were supported by information furnished by a literature review, psychology coursework, and the analysis of New Jersey playgrounds as case studies.Considering the viewpoints of different people, while keeping the child’s needs in the foreground, these perspectives were applied to both traditional equipment and their current day inclusive counterparts to understand how they can be improved. This meant studying whether they were designed for inclusive, ADA, or universal purposes. As a result of these studies of past and present playgrounds through the eyes of an extensive group of people, the theory that playgrounds can benefit children with Down Syndrome both physically and psychologically was demonstrated through the inclusion solutions.

Evolution and stochastic dynamics in complex systems

description: The dissertation provides an insight on the mathematical modeling of two complex systems. Chapter 1-4 are about the biophysical model we developed for enzyme evolution. The model predicts the reaction rates as a function of the enzyme sequence. The free energies in Michaelis-Menten kinetics are represented as a function of one amino-acid contribution and two amino-acid pairs of the enzyme sequence. Our model predicts reaction-rates with high accuracy and relatively few coupling terms. The sparseness in coupling terms results in highly interpretable Michaelis-Menten energy landscapes which exhibit little non-linearity. Chapter 5-9 talk about modeling first-passage properties of random-walks on a community-structured network. The properties are exploited in developing an algorithm to partition the network into communities. On testing our algorithm on multiple artificial and real-world networks, we find that it performs better or as well as the other competitive algorithms.
Breaking reciprocity with bilinear property: from static systems to dynamic problems

description: Reciprocity is a fundamental physical principle of wave motion, which maintains the symmetric property of wave transmission between a source and a receiver. Although widely used in many applicable techniques of quality evaluation, this principle restricts the sophisticated wave control, such as one-way propagation and directional wave scattering. A passive method of breaking reciprocity, achieved by the combination of characteristic bilinear property and necessary spatial asymmetry, is proposed and discussed in this work. The bilinear stiffness is unique among nonlinear mechanisms in that it is independent of amplitude but sensitive to the sign of the wave motion. Spatial asymmetric setup is versatile and flexible, depending on the amount of bilinearity applied and the spatial dimension, one or two as considered here. Our nonreciprocal designs start with a fundamental candidate, a discrete two-degree-of-freedom bilinear spring-mass chain structure, demonstrating nonreciprocity in both static and dynamic conditions. Then a sequence of modulated nonreciprocal models are proposed and their properties examined: expansion of the fundamental bilinear spring and mass structure to a unidimensional long-chain system is shown to display one-way wave propagation; the further simplification of the fundamental structure results in a compact diode-like structure; a two-dimensional monatomic lattice is able to demonstrate directional and nonreciprocal wave scattering. Some problems frequently seen in nonreciprocal or nonlinear designs are discussed and solved: the mathematical tools of solving bilinear partial differential equations are introduced, and a novel set-base design method using machine learning algorithms with lower computational effort is proposed.
