2. A high throughput bispecific antibody discovery pipeline

Author: Segaliny, Aude I, Jayaraman, Jayapriya, Chen, Xiaoming, Chong, Jonathan, Luxon, Ryan, Fung, Audrey, Fu, Qiwei, Jiang, Xianzhi, Rivera, Rodrigo, Ma, Xiaoya, Ren, Ci, Zimak, Jan, Hedde, Per Niklas, Shang, Yonglei, Wu, George, and Zhao, Weian

Abstract: Bispecific antibodies (BsAbs) represent an emerging class of immunotherapy, but inefficiency in the current discovery has limited their broad clinical availability. Here we report a high throughput, agnostic, single-cell-based functional screening pipeline, comprising molecular and cell engineering for efficient generation of BsAb library cells, followed by functional interrogation at the single-cell level to identify and sort positive clones and downstream sequence identification and functionality characterization. Using a CD19xCD3 bispecific T cell engager (BiTE) as a model, we demonstrate that our single-cell platform possesses a high throughput screening efficiency of up to one and a half million variant library cells per run and can isolate rare functional clones at a low abundance of 0.008%. Using a complex CD19xCD3 BiTE-expressing cell library with approximately 22,300 unique variants comprising combinatorially varied scFvs, connecting linkers and VL/VH orientations, we have identified 98 unique clones, including extremely rare ones (~ 0.001% abundance). We also discovered BiTEs that exhibit novel properties and insights to design variable preferences for functionality. We expect our single-cell platform to not only increase the discovery efficiency of new immunotherapeutics, but also enable identifying generalizable design principles based on an in-depth understanding of the inter-relationships between sequence, structure, and function.

Abstract: BackgroundDuring the COVID-19 pandemic, decreased volumes of stroke admissions and mechanical thrombectomy were reported. The study's objective was to examine whether subarachnoid haemorrhage (SAH) hospitalisations and ruptured aneurysm coiling interventions demonstrated similar declines.MethodsWe conducted a cross-sectional, retrospective, observational study across 6 continents, 37 countries and 140 comprehensive stroke centres. Patients with the diagnosis of SAH, aneurysmal SAH, ruptured aneurysm coiling interventions and COVID-19 were identified by prospective aneurysm databases or by International Classification of Diseases, 10th Revision, codes. The 3-month cumulative volume, monthly volumes for SAH hospitalisations and ruptured aneurysm coiling procedures were compared for the period before (1 year and immediately before) and during the pandemic, defined as 1 March-31 May 2020. The prior 1-year control period (1 March-31 May 2019) was obtained to account for seasonal variation.FindingsThere was a significant decline in SAH hospitalisations, with 2044 admissions in the 3 months immediately before and 1585 admissions during the pandemic, representing a relative decline of 22.5% (95% CI -24.3% to -20.7%, p

6. Robust triboelectric charging of identical balloons of different radii

Author: Vera, Francisco, Rivera, Rodrigo, Ortiz, Manuel, and Horta-Rangel, Francisco Antonio
Subjects: Physics - Physics Education
Abstract: Electrification by rubbing different materials is a well known phenomenon with a history that begun more than five centuries BC. However, simple experiments can lead to contradictory or inconsistent results and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical materials is possible. In this work we want to highlight some historical aspects of triboelectricity that could enrich the discussion of electrostatics in an undergraduate physics course. We will focus on the effect of strain on the triboelectric properties of a sample, which we think is not well known to physics teachers. We will show that it is possible to obtain robust polarities by rubbing identical rubber balloons of different radii and we will also show that this charging method can be very useful in introductory physics courses.

7. Faster and Smaller Two-Level Index for Network-based Trajectories

Author: Rivera, Rodrigo, Rodríguez, Andrea, and Seco, Diego
Subjects: Computer Science - Data Structures and Algorithms
Abstract: Two-level indexes have been widely used to handle trajectories of moving objects that are constrained to a network. The top-level of these indexes handles the spatial dimension, whereas the bottom level handles the temporal dimension. The latter turns out to be an instance of the interval-intersection problem, but it has been tackled by non-specialized spatial indexes. In this work, we propose the use of a compact data structure on the bottom level of these indexes. Our experimental evaluation shows that our approach is both faster and smaller than existing solutions., Comment: This research has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie Actions H2020-MSCA-RISE-2015 BIRDS GA No. 690941

10. Forecasting of commercial sales with large scale Gaussian Processes

Author: Rivera, Rodrigo and Burnaev, Evgeny
Subjects: Statistics - Applications, Statistics - Machine Learning
Abstract: This paper argues that there has not been enough discussion in the field of applications of Gaussian Process for the fast moving consumer goods industry. Yet, this technique can be important as it e.g., can provide automatic feature relevance determination and the posterior mean can unlock insights on the data. Significant challenges are the large size and high dimensionality of commercial data at a point of sale. The study reviews approaches in the Gaussian Processes modeling for large data sets, evaluates their performance on commercial sales and shows value of this type of models as a decision-making tool for management., Comment: 1o pages, 5 figures

11. The 'Nature of Science' and the Perils of Epistemic Relativism

Author: Romero-Maltrana, Diego, Benitez, Federico, Vera, Francisco, and Rivera, Rodrigo
Abstract: There is an increasing demand in the field of science education for the incorporation of philosophical and sociological aspects that are related to the scientific enterprise in school curricula, to the extent that the incorporation of these aspects is now considered a necessity. Several of these aspects can be categorised within the framework of the "nature of science," or NOS. We warn that a possible misinterpretation of the "common view" of NOS tenets can lead to epistemic relativism. We pay special attention to the empirical and objective nature of science because these important features, properly understood, can help eliminate subjective flaws and protect against relativism. Some of the epistemological concepts that are relevant to this discussion are disambiguated in an attempt to prevent the temptation to take views to an extreme, as has occurred in some cases. We expect this analysis to contribute to the extant literature by improving how science is presented in the classroom without oversimplifying scientific practice.

27. Statical Numerical Analysis and Material Optimization of Arthropod-Inspired Hexapod Robots for Disaster Rescue Applications

Author: Cruz-López, Salvador, Urriolagoitia-Calderón, Guillermo Manuel, Romero-Ángeles, Beatriz, Urriolagoitia-Sosa, Guillermo, Marquet-Rivera, Rodrigo Arturo, Hernández-Vázquez, Rosa Alicia, and Mastache-Miranda, Octavio Alejandro
Abstract: The development of arthropod-inspired robotic architecture, modeled after the limbs of insects and other animals, has enabled robots to behave more flexibly and adaptively in different environments. Among these designs, hexapod robots have gained significant attention due to their potential use in disaster rescue scenarios, providing vital support for lifesaving and damage control in emergency situations. This study addresses the numerical analysis of a hexapod robot specifically tailored for use in disaster areas, with a particular focus on the crucial aspect of material optimization. Hexapod robots, equipped with articulated legs that mimic insect-like movements, have shown remarkable success in exploration tasks, especially in navigating hard-to-reach places. The main body of the robot was designed using durable yet lightweight materials to optimize load-bearing capacity for the required equipment and rescue tools. A thorough static numerical analysis was performed to ensure the structural integrity and efficiency of the robot. Finite element simulation programs were used for the static numerical analysis, allowing evaluation of the stresses and deformations to which the robot would be subjected under various loading conditions. The selection of materials played a critical role in improving the robot's performance and survivability during disaster operations. Various materials, including composites and advanced alloys, were tested, and analyzed for their mechanical properties and suitability for harsh conditions. In particular, the resistance of the robot to the impact of a falling cubic reinforced concrete element was investigated by simulating a stone collapse. The results of this study shed light on the influence of materials on the robot's ability to cope with unpredictable and challenging scenarios, ultimately contributing to the development of more robust and reliable Hexapod robots for disaster operations. The results of this research contribute significantly to ongoing advances in robotics technology for disaster operations. By leveraging the unique characteristics of arthropod-inspired Hexapod robots and optimizing their material composition, this study highlights the potential of these mobile devices to revolutionize rescue operations in challenging and hazardous environments, ultimately saving lives and minimizing the impact of disasters.

28. Gracias a Dios: fronterización y aumento de los costos y riesgos de la migración en el departamento de Huehuetenango, Guatemala

Author: Armas Lucas, Álvaro Napoleón, Villafuerte Solís, Daniel, Megchún Rivera, Rodrigo, Armas Lucas, Álvaro Napoleón, Villafuerte Solís, Daniel, and Megchún Rivera, Rodrigo
Abstract: The article describes and analyzes the relatively recent emergence of a migratory route in the department of Huehuetenango, Guatemala; one that ends at the border point of Gracias a Dios. As the text proposes, this as a product of the frontier process of the Central American country; represented by the increase in the controls, persecution and criminalization of undocumented migration, as well as in the rigors and risks that increasingly accompany the practice. The questions that the article implicitly addresses are: how have some of the main actors in migration (particularly “coyotes”) responded to the increase in frontier process? What are some of the economic effects and perceptions in the study locality (Gracias a Dios), as a result of the deployment of a migratory intermediation industry? What are some of the consequences of the political and economic transformations that currently characterize undocumented migration (its increasing persecution and cost) for migrants? The concept that we propose is that of frontier process, understood as the establishment, deployment or hardening of legal, procedural and even physical fronts, in the face of different flows such as migration. Which allows us to recognize that borders are mobile and historical. Some of the findings of the article are that in the framework of the legal persecution of "illicit traffickers of persons" in Guatemala, "coyotes" or "polleros" have assumed managerial functions; at the time that the figure of the "guide" has emerged in the accompaniment of migrants. As a corollary, the tightening of immigration laws has only made migration mediation more flexible and widespread. Finally, that the increase in the monetary costs of illegal international migration implies, paradoxically, that migrants must get into debt or invest considerable monetary sums to access to the desired jobs., El artículo describe y analiza el relativamente reciente surgimiento de una ruta migratoria en el departamento de Huehuetenango, Guatemala; la que desemboca en el punto fronterizo de Gracias a Dios. Ello como producto, según propone el texto, del proceso de fronterización del país centroamericano; representado por el aumento tanto en los controles, persecución y criminalización de la migración indocumentada, así como en los rigores y riesgos que de manera creciente acompañan a la práctica. Las preguntas que implícitamente encara el artículo son: ¿cómo han respondido algunos de los principales actores de la migración (particularmente, “los coyotes”) ante el aumento de la fronterización? ¿Cuáles son algunos de los efectos económicos y de las percepciones en la localidad de estudio (Gracias a Dios), a raíz del despliegue de una industria de intermediación migratoria? ¿Cuáles son algunas de las consecuencias de las transformaciones políticas y económicas que caracterizan actualmente a la migración indocumentada (su creciente persecución y encarecimiento), para las personas migrantes? El concepto que proponemos es el de fronterización, entendido como el establecimiento, despliegue o endurecimiento de frentes jurídicos, procedimentales e incluso físicos, de cara a distintos flujos como la migración. Lo cual nos permite reconocer que las fronteras son móviles e históricas. Algunos hallazgos del artículo son, que en el marco de la persecución legal a los “traficantes ilícitos de personas” en Guatemala, “los coyotes” o “polleros” han asumido funciones gerenciales; al tiempo en que ha surgido la figura del “guía” (subordinado a los coyotes) en el acompañamiento a los migrantes. Como corolario de lo anterior, que el endurecimiento de las leyes migratorias sólo ha hecho más flexible y extendida la intermediación de la migración. Finalmente, que el incremento en los costos monetarios de la migración internacional ilegalizada implica, paradójicamente, que los migrantes deben ende

29. La muerte tiene permiso. Ensayo sobre la necropolítica hacia la migración de tránsito por México

Author: Megchún Rivera, Rodrigo, Guevara González, Yaatsil, Megchún Rivera, Rodrigo, and Guevara González, Yaatsil
Abstract: This article poses and analyzes the contemporary policy of containment of transit migration, by the Mexican State, as a necropolitics (Mbembe, 2011 [2006]). That is, the self-assignment by government personnel of the decision, and the consequent treatment, of which population sectors can live and persist, and which can be separated, detained, eliminated. Consistent with the analysis by Mbembe (2011 [2006]) and Foucault (2006 [1978]), the article argues that necropolitics of migration is part of a broader necropower of segregation, exclusion, and exploitation of the migrant population. Likewise, it is argued that irregularization and the deployment of borders are some of the main mechanisms that enable an exclusive treatment of migrants. Finally, within the framework of necropolitics, containment policies are analyzed in the context of the SARS-CoV-2 virus pandemic., Este artículo plantea y analiza a la política contemporánea de contención de la migración de tránsito, por parte del Estado mexicano, como una necropolítica (Mbembe, 2011 [2006]). Esto es, la autoasignación por parte del personal gubernamental de la decisión, y el consiguiente tratamiento, de que sectores poblacionales pueden vivir y persistir, y cuáles pueden ser separados, detenidos, eliminados. De conformidad con el análisis de Mbembe (2011 [2006]) y Foucault (2006 [1978]), en el artículo se plantea que la necropolítica migratoria es parte de un necropoder más amplio de segregación, exclusión y explotación de la población migrante. Asimismo, se plantea que la irregularización y el despliegue de fronteras son algunos de los principales mecanismos que posibilitan un tratamiento excluyente hacia los migrantes. Finalmente, en el marco de la necropolítica se analizan las políticas de contención en el contexto de la pandemia por el virus SARS-CoV-2.

Abstract: Background and Objectives: Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020)., Methods: We conducted a longitudinal retrospective study across 6 continents, 56 countries, and 275 stroke centers. We collected volume data for COVID-19 admissions and 4 stroke metrics: ischemic stroke admissions, ICH admissions, IVT treatments, and mechanical thrombectomy procedures. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases., Results: There were 148,895 stroke admissions in the 1 year immediately before compared with 138,453 admissions during the 1-year pandemic, representing a 7% decline (95% CI [95% CI 7.1–6.9]; p < 0.0001). ICH volumes declined from 29,585 to 28,156 (4.8% [5.1–4.6]; p < 0.0001) and IVT volume from 24,584 to 23,077 (6.1% [6.4–5.8]; p < 0.0001). Larger declines were observed at high-volume compared with low-volume centers (all p < 0.0001). There was no significant change in mechanical thrombectomy volumes (0.7% [0.6–0.9]; p = 0.49). Stroke was diagnosed in 1.3% [1.31–1.38] of 406,792 COVID-19 hospitalizations. SARS-CoV-2 infection was present in 2.9% ([2.82–2.97], 5,656/195,539) of all stroke hospitalizations., Discussion: There was a global decline and shift to lower-volume centers of stroke admission volumes, ICH volumes, and IVT volumes during the 1st year of the COVID-19 pandemic compared with the prior year. Mechanical thrombectomy volumes were preserved. These results suggest preservation in the stroke care of higher severity of disease through the first pandemic year., Trial Registration Information: This study is registered under NCT04934020.

32. Interference Rate of Radiation of 2 Charges in Circular Motion

Author: Villarroel, Danilo and Rivera, Rodrigo
Subjects: High Energy Physics - Phenomenology
Abstract: We present an exact formula for the computation of the interference rate of radiation in the case of two charges revolving with constant angular velocity at opposite ends of a diameter in a fixed circle. The formula is valid for arbitrary velocities of the charges, and can be easily studied by numerical methods, even for velocities very close to the velocity of light. For ultrarelativistic motion, the interference rate of radiation behaves as $\ln(1-v^2/c^2)^{-1/2}$, which contrasts with the behavior $(1 - v^2/c^2)^{-2}$ for the rate of radiation for one charge in circular motion. This is the first exact calculation for the interference rate of radiation of two relativistic charges, and it is useful in connection with the old controversy about the correctness of the Lorentz-Dirac equations of motion for more than one charge., Comment: 16 pages and 4 figs.

Abstract: Background and ObjectivesDeclines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).MethodsWe conducted a longitudinal retrospective study across 6 continents, 56 countries, and 275 stroke centers. We collected volume data for COVID-19 admissions and 4 stroke metrics: ischemic stroke admissions, ICH admissions, IVT treatments, and mechanical thrombectomy procedures. Diagnoses were identified by theirICD-10codes or classifications in stroke databases.ResultsThere were 148,895 stroke admissions in the 1 year immediately before compared with 138,453 admissions during the 1-year pandemic, representing a 7% decline (95% CI [95% CI 7.1–6.9];p< 0.0001). ICH volumes declined from 29,585 to 28,156 (4.8% [5.1–4.6];p< 0.0001) and IVT volume from 24,584 to 23,077 (6.1% [6.4–5.8];p< 0.0001). Larger declines were observed at high-volume compared with low-volume centers (allp< 0.0001). There was no significant change in mechanical thrombectomy volumes (0.7% [0.6–0.9];p= 0.49). Stroke was diagnosed in 1.3% [1.31–1.38] of 406,792 COVID-19 hospitalizations. SARS-CoV-2 infection was present in 2.9% ([2.82–2.97], 5,656/195,539) of all stroke hospitalizations.DiscussionThere was a global decline and shift to lower-volume centers of stroke admission volumes, ICH volumes, and IVT volumes during the 1st year of the COVID-19 pandemic compared with the prior year. Mechanical thrombectomy volumes were preserved. These results suggest preservation in the stroke care of higher severity of disease through the first pandemic year.Trial Registration InformationThis study is registered underNCT04934020.

Abstract: Background Aneurysm recurrence remains a challenge when coiling cerebral aneurysms. Development of next generation coils has focused on accelerating thrombus maturation and increasing coil packing density. Ultra low density shape memory polymer is a novel embolic material designed for this purpose. The polymer is crimped over a platinum-tungsten coil for catheter delivery and self-expands to a predefined volume on contact with blood. Methods This prospective study in humans evaluated aneurysms 5-16 mm (inclusive) in diameter that were indicated for endovascular coil embolization. At least 70% coil volume was required to be shape memory polymer coils. Patients were followed-up according to standard of care for 12 months. Results Nine patients (89% women, mean age 55.8±11.7 years) were treated with shape memory polymer coils and completed 12 months of follow-up. Aneurysms were all unruptured and were in the ophthalmic segment of the internal carotid artery (n=7), posterior communicating artery, and anterior cerebral artery A1-A2 segment. Aneurysms were a mean of 7.8±2.9 mm in diameter (range 5.2-14.9 mm). The mean packing density based on unexpanded polymer was 17±6%. Packing density based on expanded polymer was 43±13%. At 12 months, no recurrence had occurred, and a Raymond-Roy occlusion classification of 1 (n=5) or 2 (n=4) was observed. No serious adverse events related to the study device occurred over the 12 months after the procedure. Conclusions Shape memory polymer coils were safe and effective in treating intracranial aneurysms over 12 months in this first study in human subjects. [ABSTRACT FROM AUTHOR]

Abstract: Introducción Vivimos una época dominada por el ideal de autonomía individual, que ha de realizarse mediante redes de información instantáneas y una infinidad de mercados planetarios en los que, potencialmente, todos los aspectos de la vida se negocian según su valor de cambio. En esta articulación reside el alma del neo-liberalismo.

Abstract: Este libro reúne miradas etnográficas, históricas y arqueológicas en torno a las formas de cargar y descargar en el desierto de Atacama. Se carga y se descarga entre sistemas técnicos heterogéneos se descarga una llama para cargar un camión, se descarga un camión para cargar un bote -, de modo que estudiándolos se vuelve visible la diversidad de sistemas que intervienen y sus cadenas de relaciones. Esta operación plantea además el problema de los recipientes (vasijas, frascos, sacos, barriles) y códigos (volumen, precio, peso, viajes) que permiten traducir la materia de un sistema a otro y que sobrescriben formas locales de comprender, tratar y medir la naturaleza: la historia de la difusión del saco o del kilo en los Andes son problemas esenciales a una antropología de la naturaleza. En lo que respecta a la historia de la técnica, los puntos de carga y descarga hacen aparecer la realidad local de las máquinas: una máquina de vapor es universal, la misma en el desierto de Atacama que en Alemania, pero la manera como se la carga y descarga, en cambio, depende de su concretización en un espacio físico, social y cultural particular. Los sitios de carga y descarga son los puntos más políticos del sistema; ahí se instalan las aduanas, las pesas, los controles; también se roba o se engaña. Así, las operaciones de carga y descarga permiten comprender las trayectorias históricas, técnicas y sociales que integran el devenir de un territorio en territorio extractivo.
