Selective active resonance tuning for multi-mode nonlinear photonic cavities.

Resonant enhancement of nonlinear photonic processes is critical for the scalability of applications such as long-distance entanglement generation. To implement nonlinear resonant enhancement, multiple resonator modes must be individually tuned onto a precise set of process wavelengths, which requires multiple linearly-independent tuning methods. Using coupled auxiliary resonators to indirectly tune modes in a multi-resonant nonlinear cavity is particularly attractive because it allows the extension of a single physical tuning mechanism, such as thermal tuning, to provide the required independent controls. Here we model and simulate the performance and tradeoffs of a coupled-resonator tuning scheme which uses auxiliary resonators to tune specific modes of a multi-resonant nonlinear process. Our analysis determines the tuning bandwidth for steady-state mode field intensity can significantly exceed the inter-cavity coupling rate g if the total quality factor of the auxiliary resonator is higher than the multi-mode main resonator. Consequently, over-coupling a nonlinear resonator mode to improve the maximum efficiency of a frequency conversion process will simultaneously expand the auxiliary resonator tuning bandwidth for that mode, indicating a natural compatibility with this tuning scheme. We apply the model to an existing small-diameter triply-resonant ring resonator design and find that a tuning bandwidth of 136 GHz ≈ 1.1 nm can be attained for a mode in the telecom band while limiting excess scattering losses to a quality factor of 106. Such range would span the distribution of inhomogeneously broadened quantum emitter ensembles as well as resonator fabrication variations, indicating the potential for the auxiliary resonators to enable not only low-loss telecom conversion but also the generation of indistinguishable photons in a quantum network.

Homicide or Happiness: Did Folate Fortification and Public Health Campaigns Influence Homicide Rates and the Great American Crime Decline?

The last several years have witnessed a remarkable growth in research directed at nutrition and behavior, with increased interest in the field of nutritional criminology. It is becoming clear that dietary patterns and specific nutrients play an important role in cognition and behavior, including those related to aggression, violence, and antisocial activity. Included in this expanding knowledge base is the recognition that folate, through multiple pathways, including enzymatic reactions and gut microbiome ecology, plays a critical role in central nervous system functioning. These mechanistic advances allow for a retrospective analysis of a topic that remains unexplained-the sudden and unpredicted drop in homicide and other violent crime rates in the United States and other nations in the 1990s. Here, we revisit this marked reduction in homicide rates through the lens of the coincident public health campaign (and subsequent mandatory fortification) to increase folic acid intake. Based on objectively measured blood folate levels through the National Health and Nutrition Examination Surveys, there is little doubt that tissue folate witnessed a dramatic rise at the national level from 1988 through 2000. Drawing from accumulated and emerging research on the neurobehavioral aspects of folate, it is our contention that this relatively sudden and massive increase in tissue folate levels may have contributed to reductions in violent crime in the United States.

Nutritional Criminology: Why the Emerging Research on Ultra-Processed Food Matters to Health and Justice.

There is mounting concern over the potential harms associated with ultra-processed foods, including poor mental health and antisocial behavior. Cutting-edge research provides an enhanced understanding of biophysiological mechanisms, including microbiome pathways, and invites a historical reexamination of earlier work that investigated the relationship between nutrition and criminal behavior. Here, in this perspective article, we explore how this emergent research casts new light and greater significance on previous key observations. Despite expanding interest in the field dubbed 'nutritional psychiatry', there has been relatively little attention paid to its relevancy within criminology and the criminal justice system. Since public health practitioners, allied mental health professionals, and policymakers play key roles throughout criminal justice systems, a holistic perspective on both historical and emergent research is critical. While there are many questions to be resolved, the available evidence suggests that nutrition might be an underappreciated factor in prevention and treatment along the criminal justice spectrum. The intersection of nutrition and biopsychosocial health requires transdisciplinary discussions of power structures, industry influence, and marketing issues associated with widespread food and social inequalities. Some of these discussions are already occurring under the banner of 'food crime'. Given the vast societal implications, it is our contention that the subject of nutrition in the multidisciplinary field of criminology-referred to here as nutritional criminology-deserves increased scrutiny. Through combining historical findings and cutting-edge research, we aim to increase awareness of this topic among the broad readership of the journal, with the hopes of generating new hypotheses and collaborations.

"Food faddists and pseudoscientists!": Reflections on the history of resistance to ultra-processed foods.

The term 'ultra-processed food' emerged in the 1980s, mostly used in reference to highly-processed convenience foods and snacks, often energy-dense, poor in nutrients, and inclusive of various synthetic additives such as emulsifiers, colors, artificial sweeteners, and/or flavor enhancers. Concern over such foods was part of the growing holistic and environmental health movements of the 1970-80s; yet, those who raised alarm about the encroachment of ultra-processed foods were often labeled, especially by industry and their powerful allies, as 'food faddists' and 'pseudoscientists'. Today, the topic of ultra-processed foods is generating massive personal, public, and planetary health interest. However, other than discussing the history of the NOVA food classification system, a useful tool that has allowed researchers to more accurately separate foods based on processing, most lay media and academic articles are ahistorical. That is, there is a tendency to present the term ultra-processed food(s) as a relatively new entrance into the lexicon, and by default, the idea that health-related pushback on ultra-processed foods is a relatively new phenomenon. This omission overlooks decades of determined advocacy and clinical work, much of it by pioneers within the holistic medicine (now integrative, functional, and lifestyle medicine) movement. Here in this reflection paper, the authors will use historical research and reporting to fill in the historical gap and articulate the saliency of why it matters.

Beyond Plants: The Ultra-Processing of Global Diets Is Harming the Health of People, Places, and Planet.

Global food systems are a central issue for personal and planetary health in the Anthropocene. One aspect of major concern is the dramatic global spread of ultra-processed convenience foods in the last 75 years, which is linked with the rising human burden of disease and growing sustainability and environmental health challenges. However, there are also calls to radically transform global food systems, from animal to plant-derived protein sources, which may have unintended consequences. Commercial entities have moved toward this "great plant transition" with vigor. Whether motivated by profit or genuine environmental concern, this effort has facilitated the emergence of novel ultra-processed "plant-based" commercial products devoid of nutrients and fiber, and sometimes inclusive of high sugar, industrial fats, and synthetic additives. These and other ingredients combined into "plant-based" foods are often assumed to be healthy and lower in calorie content. However, the available evidence indicates that many of these products can potentially compromise health at all scales-of people, places, and planet. In this viewpoint, we summarize and reflect on the evidence and discussions presented at the Nova Network planetary health meeting on the "Future of Food", which had a particular focus on the encroachment of ultra-processed foods into the global food supply, including the plant-sourced animal protein alternatives (and the collective of ingredients therein) that are finding their way into global fast-food chains. We contend that while there has been much uncritical media attention given to the environmental impact of protein and macronutrient sources-meat vs. novel soy/pea protein burgers, etc.-the impact of the heavy industrial processing on both human and environmental health is significant but often overlooked, including effects on cognition and mental health. This calls for a more nuanced discourse that considers these complexities and refocuses priorities and value systems towards mutualistic solutions, with co-benefits for individuals, local communities, and global ecology.

The Founder: Dispositional Greed, Showbiz, and the Commercial Determinants of Health.

Marketing unhealthy products by multinational corporations has caused considerable harm to individual health, collective wellbeing, and environmental sustainability. This is a growing threat to all societies and a significant contributor to the rising global burden of non-communicable diseases and early mortality. While there is growing consideration of the commercial determinants of health, this is largely focused on the methods by which unhealthy products are marketed and disseminated, including efforts to manipulate policy. Little attention has been paid to the underlying psychological traits and worldviews that are driving corporate greed. Here, we consider the role of "dispositional greed" in the commercial determinants of health with a focus on the historical attitudes and culture in the ultra-processed food industry-exemplified by "The Founder" of the McDonald's franchise. We argue that greed and associated psychological constructs, such as social dominance orientation and collective narcissism, permeate the commercial determinants of health at a collective level. This includes how a culture of greed within organizations, and individual dispositional greed, can magnify and cluster at scale, perpetuated by social dominance orientation. We also consider the ways in which "showbiz" marketing specifically targets marginalized populations and vulnerable groups, including children-in ways that are justified, or even celebrated despite clear links to non-communicable diseases and increased mortality. Finally, we consider how greed and exploitative mindsets mirror cultural values and priorities, with trends for increasing collective narcissism at scale, recognizing that many of these attitudes are cultivated in early life. A healthier future will depend on navigating a path that balances material prosperity with physical and spiritual wellbeing. This will require cultural change that places higher value on kindness, reciprocity, and mutualistic values especially in early life, for more equitable flourishing.

Vitality Revisited: The Evolving Concept of Flourishing and Its Relevance to Personal and Public Health.

Human flourishing, the state of optimal functioning and well-being across all aspects of an individual's life, has been a topic of philosophical and theological discussion for centuries. In the mid-20th century, social psychologists and health scientists began exploring the concept of flourishing in the context of health and high-level wellness. However, it is only in recent years, in part due to the USD 43 million Global Flourishing Study including 22 countries, that flourishing has entered the mainstream discourse. Here, we explore this history and the rapid acceleration of research into human flourishing, defined as "the relative attainment of a state in which all aspects of a person's life are good" by the Harvard University's Flourishing Program. We also explore the construct of "vitality", which refers to a sense of aliveness, energy, and motivation; we contend that this has been neglected in the flourishing movement. We explore why incorporating measures of vitality, together with a broader biopsychosocial approach, considers all dimensions of the environment across time (the total exposome), which will greatly advance research, policies, and actions to achieve human flourishing.

Triply-resonant sum frequency conversion with gallium phosphide ring resonators.

We demonstrate quasi-phase matched, triply-resonant sum frequency conversion in 10.6-µm-diameter integrated gallium phosphide ring resonators. A small-signal, waveguide-to-waveguide power conversion efficiency of 8 ± 1.1%/mW; is measured for conversion from telecom (1536 nm) and near infrared (1117 nm) to visible (647 nm) wavelengths with an absolute power conversion efficiency of 6.3 ± 0.6%; measured at saturation pump power. For the complementary difference frequency generation process, a single photon conversion efficiency of 7.2%/mW from visible to telecom is projected for resonators with optimized coupling. Efficient conversion from visible to telecom will facilitate long-distance transmission of spin-entangled photons from solid-state emitters such as the diamond NV center, allowing long-distance entanglement for quantum networks.

Exiting the Anthropocene: Achieving personal and planetary health in the 21st century.

Planetary health provides a perspective of ecological interdependence that connects the health and vitality of individuals, communities, and Earth's natural systems. It includes the social, political, and economic ecosystems that influence both individuals and whole societies. In an era of interconnected grand challenges threatening health of all systems at all scales, planetary health provides a framework for cross-sectoral collaboration and unified systems approaches to solutions. The field of allergy is at the forefront of these efforts. Allergic conditions are a sentinel measure of environmental impact on human health in early life-illuminating how ecological changes affect immune development and predispose to a wider range of inflammatory noncommunicable diseases (NCDs). This shows how adverse macroscale ecology in the Anthropocene penetrates to the molecular level of personal and microscale ecology, including the microbial systems at the foundations of all ecosystems. It provides the basis for more integrated efforts to address widespread environmental degradation and adverse effects of maladaptive urbanization, food systems, lifestyle behaviors, and socioeconomic disadvantage. Nature-based solutions and efforts to improve nature-relatedness are crucial for restoring symbiosis, balance, and mutualism in every sense, recognizing that both personal lifestyle choices and collective structural actions are needed in tandem. Ultimately, meaningful ecological approaches will depend on placing greater emphasis on psychological and cultural dimensions such as mindfulness, values, and moral wisdom to ensure a sustainable and resilient future.

Precise electron beam-based target-wavelength trimming for frequency conversion in integrated photonic resonators.

We demonstrate post-fabrication target-wavelength trimming with a gallium phosphide on a silicon nitride integrated photonic platform using controlled electron-beam exposure of hydrogen silsesquioxane cladding. A linear relationship between the electron-beam exposure dose and resonant wavelength red-shift enables deterministic, individual trimming of multiple devices on the same chip to within 30 pm of a single target wavelength. Second harmonic generation from telecom to near infrared at a target wavelength is shown in multiple devices with quality factors on the order of 104. Post-fabrication tuning is an essential tool for targeted wavelength applications including quantum frequency conversion.

Earth Dreams: Reimagining ARPA for Health of People, Places and Planet.

Bold new approaches are urgently needed to overcome global health challenges. The proposed Advanced Research Projects Agency for Health (ARPA-H) is intended to provide rapid health breakthroughs. While new technologies for earlier disease detection and more effective treatment are critical, we urge equal attention be given to the wider (physical, emotional, social, political, and economic) environmental ecosystems driving the non-communicable disease (NCD) crisis in the first place. This requires an integrated, cross-sectoral vision that spans the interwoven connections affecting health across the scales of people, places, and planet. This wider "exposome" perspective considers biopsychosocial factors that promote resilience and reduce vulnerabilities of individuals and communities over time-the many variables driving health disparities. Since life course health is strongly determined by early life environments, early interventions should be prioritized as a matter of effectiveness and social justice. Here, we explore the origins of the Advanced Research Project Agency and point to its potential to build integrated solutions, with wisdom and ethical value systems as a compass. Since the planned ARPA-H is anticipated to spawn international collaborations, the imagined concept is of relevance to a broad audience of researchers. With appropriate input, the quest for health equity through personalized, precision medicine while deconstructing unacceptable structural inequities may be accelerated.

Project Earthrise: Proceedings of the Ninth Annual Conference of inVIVO Planetary Health.

The "Earthrise" photograph, taken on the 1968 Apollo 8 mission, became one of the most significant images of the 20th Century. It triggered a profound shift in environmental awareness and the potential for human unity-inspiring the first Earth Day in 1970. Taking inspiration from these events 50 years later, we initiated Project Earthrise at our 2020 annual conference of inVIVO Planetary Health. This builds on the emergent concept of planetary health, which provides a shared narrative to integrate rich and diverse approaches from all aspects of society towards shared solutions to global challenges. The acute catastrophe of the COVID-19 pandemic has drawn greater attention to many other interconnected global health, environmental, social, spiritual, and economic problems that have been underappreciated or neglected for decades. This is accelerating opportunities for greater collaborative action, as many groups now focus on the necessity of a "Great Transition". While ambitious integrative efforts have never been more important, it is imperative to apply these with mutualistic value systems as a compass, as we seek to make wiser choices. Project Earthrise is our contribution to this important process. This underscores the imperative for creative ecological solutions to challenges in all systems, on all scales with advancing global urbanization in the digital age-for personal, environmental, economic and societal health alike. At the same time, our agenda seeks to equally consider our social and spiritual ecology as it does natural ecology. Revisiting the inspiration of "Earthrise", we welcome diverse perspectives from across all dimensions of the arts and the sciences, to explore novel solutions and new normative values. Building on academic rigor, we seek to place greater value on imagination, kindness and mutualism as we address our greatest challenges, for the health of people, places and planet.

Golden Age of Medicine 2.0: Lifestyle Medicine and Planetary Health Prioritized.

The 'golden age of medicine' - the first half of the 20th century, reaching its zenith with Jonas Salk's 1955 polio vaccine - was a time of profound advances in surgical techniques, immunization, drug discovery, and the control of infectious disease; however, when the burden of disease shifted to lifestyle-driven, chronic, non-communicable diseases, the golden era slipped away. Although modifiable lifestyle practices now account for some 80% of premature mortality, medicine remains loathe to embrace lifestyle interventions as medicine Here, we argue that a 21st century golden age of medicine can be realized; the path to this era requires a transformation of medical school recruitment and training in ways that prioritize a broad view of lifestyle medicine. Moving beyond the basic principles of modifiable lifestyle practices as therapeutic interventions, each person/community should be viewed as a biological manifestation of accumulated experiences (and choices) made within the dynamic social, political, economic and cultural ecosystems that comprise their total life history. This requires an understanding that powerful forces operate within these ecosystems; marketing and neoliberal forces push an exclusive 'personal responsibility' view of health - blaming the individual, and deflecting from the large-scale influences that maintain health inequalities and threaten planetary health. The latter term denotes the interconnections between the sustainable vitality of person and place at all scales. We emphasize that barriers to planetary health and the clinical application of lifestyle medicine - including authoritarianism and social dominance orientation - are maintaining an unhealthy status quo.

Recent thecideide brachiopods from a submarine cave in the Department of Mayotte (France), northern Mozambique Channel.

For the first time large numbers of thecideide brachiopods have been collected from the Mozambique Channel, more particularly from the western part of the Comorian Island of Mayotte (France). The moderately diverse brachiopod fauna is from a submarine cave situated on the second barrier reef encircling this island, with three different genera being found: Thecidellina, Ospreyella and Minutella. The last genus is represented by M. cf. minuta (Cooper, 1981), which was first discovered around Madagascar. Ospreyella is represented by a new species (O. mayottensis sp. nov.) as is Thecidellina, which is represented by T. leipnitzae sp. nov. This species is markedly distinct from T. europa Logan et al., 2015 from Europa Island in the southern Mozambique Channel (1,200 km south of Mayotte), providing an example of allopatric speciation in an isolated cryptic habitat.

Eighth Annual Conference of inVIVO Planetary Health: From Challenges to Opportunities.

inVIVO Planetary Health (inVIVO) is a progressive scientific movement providing evidence, advocacy, and inspiration to align the interests and vitality of people, place, and planet. Our goal is to transform personal and planetary health through awareness, attitudes, and actions, and a deeper understanding of how all systems are interconnected and interdependent. Here, we present the abstracts and proceedings of our 8th annual conference, held in Detroit, Michigan in May 2019, themed "From Challenges, to Opportunities". Our far-ranging discussions addressed the complex interdependent ecological challenges of advancing global urbanization, including the biopsychosocial interactions in our living environment on physical, mental, and spiritual wellbeing, together with the wider community and societal factors that govern these. We had a strong solutions focus, with diverse strategies spanning from urban-greening and renewal, nature-relatedness, nutritional ecology, planetary diets, and microbiome rewilding, through to initiatives for promoting resilience, positive emotional assets, traditional cultural narratives, creativity, art projects for personal and community health, and exploring ways of positively shifting mindsets and value systems. Our cross-sectoral agenda underscored the importance and global impact of local initiatives everywhere by contributing to new normative values as part of a global interconnected grass-roots movement for planetary health.

The Bell Tolls for Homeopathy: Time for Change in the Training and Practice of North American Naturopathic Physicians.

North American naturopathic medicine is a distinct form of practice that is woven into the larger fabric of integrative medicine; in a number of US states and Canadian provinces, naturopathic doctors enjoy a wide scope of practice, including the ability to make diagnoses, order tests, use medical technology, write prescription drugs, and perform minor surgeries. However, the basic premise of naturopathic medicine and its guiding principles-considering the whole person and supporting healthy lifestyle behaviors-is the unifying approach in clinical practice. In the 1970s, homeopathy-considered in many circles to be a hypothesis-driven, fringe form of alternative medicine-became embedded into the training and practice of North American naturopathic doctors. Since the earliest days of its theory (circa 1800), homeopathy has escaped, and continues to escape, biological plausibility; however, the persistence of this modality (and the insistence by both its consumers and practitioners that it provides benefit) speaks to the role of expectations, beliefs, values, agency, context effects, and the placebo-at-large. It is our contention that the progression of professional naturopathic medicine in the 21st century requires a major transition in how it approaches the subject of homeopathy. We propose that students should be encouraged to critically analyze the tenets of homeopathy, its lesser known history, and the idea of homeopathy as a biomedicine that simply awaits untold chemicophysical mechanisms. Furthermore, the modality of homeopathy should be incorporated into the larger context of placebo studies, narrative medicine, ethics, and psychotherapeutic techniques.

Preventive Medicine for Person, Place, and Planet: Revisiting the Concept of High-Level Wellness in the Planetary Health Paradigm.

Experts in preventive medicine and public health have long-since recognized that health is more than the absence of disease, and that each person in the 'waiting room' and beyond manifests the social/political/economic ecosystems that are part of their total lived experience. The term planetary health-denoting the interconnections between the health of person and place at all scales-emerged from the environmental and preventive health movements of the 1970⁻1980s. Roused by the 2015 Lancet Commission on Planetary Health report, the term has more recently penetrated mainstream academic and medical discourse. Here, we discuss the relevance of planetary health in the era of personalized medicine, gross environmental concerns, and a crisis of non-communicable diseases. We frame our discourse around high-level wellness-a concept of vitality defined by Halbert L. Dunn (1896⁻1975); high-level wellness was defined as an integrated method of functioning which is oriented toward maximizing the potential of individuals within the total lived environment. Dunn maintained that high-level wellness is also applicable to organizations, communities, nations, and humankind as a whole-stating further that global high-level wellness is a product of the vitality and sustainability of the Earth's natural systems. He called for a universal philosophy of living. Researchers and healthcare providers who focus on lifestyle and environmental aspects of health-and understand barriers such as authoritarianism and social dominance orientation-are fundamental to maintaining trans-generational vitality at scales of person, place, and planet.

Planetary Health: From the Wellspring of Holistic Medicine to Personal and Public Health Imperative.

The term planetary health - denoting the interconnections between the health of person and place at all scales - emerged from the environmental and holistic health movements of the 1970-80s; in 1980, Friends of the Earth expanded the World Health Organization definition of health, stating: "health is a state of complete physical, mental, social and ecological well-being and not merely the absence of disease - personal health involves planetary health". By the 1990s, the concept of planetary health was part of the fabric of integrative medicine; more recently, after the 2015 Lancet Commission on Planetary Health report, the concept has penetrated mainstream academic and medical discourse. Here, we explore this history and describe its relevance to contemporary healthcare; integrative medicine is uniquely positioned to educate and advocate on behalf of patients and communities (current and future generations), helping to safeguard health of person, place and planet. We use the emerging microbiome science as a way to illustrate the interconnectivity and health implications of ecosystems (including social/political/economic systems) at all scales. As highlighted in the Canmore Declaration, mainstream planetary health discourse will be strengthened by inter-professional healthcare perspectives, and a more sophisticated understanding of the ways in which social dominance orientation and medical authoritarianism compromise the World Health Organization's broad vision of global health. Planetary health isn't a "new discipline"; it is merely an extension of a concept that was understood by our ancestors, and remains the vocation of all healthcare providers. Discourse on the topic requires cultural competency, critical consciousness and a greater appreciation of marginalized voices.

North American naturopathic medicine in the 21st century: Time for a seventh guiding principle - Scientia Critica.

The World Health Organization strategy for global health includes a culturally-sensitive blending of western biomedicine with traditional forms of healing; in practical terms this approach is often referred to as integrative medicine. One distinct element within the systems of North American integrative healthcare is naturopathic medicine; while the basic premise of its fundamental approach to care - supporting healthy lifestyle behaviors - is as old as medicine itself, the early history of organized naturopathy in North America was heavy in theory and light on critical analysis. Dozens of questionable modalities and protocols have been housed under the rubric of naturopathy. It is our contention that the progression of professional naturopathic medicine in the 21st century - with goals of personal, public and planetary health - requires the active pursuit of critical analysis. We examine the primary guiding principles which drive the training and practice of North American naturopathic medicine; while these principles are laudable in the age of patient-centered care, we argue that there are shortcomings by absentia. We propose a seventh principle - Scientia Critica; that is, the ability to critically analyze accumulated knowledge - including scientific facts, knowledge about the self (critical consciousness) and values of the patient.
