Rivers and Cooperative Urban AI Ecosystems

Cities today are dynamic urban ecosystems with evolving physical, social, cultural, and technological infrastructures. Cities are increasingly embracing data-driven infrastructures and algorithmic decision-making to improve urban planning and operational efficiency as well as mobility, sustainability and safety for its residents. In this paper, I argue for a critical lens into how these inter-related urban technologies, big data and policies, constituted as Urban AI Ecosystems, can offer both challenges and opportunities in terms of their social, political and ecological impact. I examine these issues through three intersecting urban crises: climate change, pandemics, and racial discrimination, with the many contested conditions and responses emerging. I anchor my arguments using a rights-based discourse which I believe offers a crucial framework for critically examining and configuring the roles, values and ethical implications for all stakeholders including human, AI and non-human entities within an urban ecosystem.
An evolutionary game theory analysis of trust in repeated games and lessons for human-machine interactions

Introduction The actions of intelligent agents, such as chatbots, recommender systems, and virtual assistants are typically not fully transparent to the user (Beldad et al., 2016; Chung et al., 2017). Consequently, users take the risk that such agents act in ways opposed to the users’ preferences or goals (Luhmann, 1979). It is often argued that people use trust as a cognitive shortcut to reduce the complexity of such interactions. In our recent work (Han et al., 2021), we study this by using the methods of evolutionary game theory (EGT) to examine the viability of trust-based strategies in the context of an iterated prisoner’s dilemma (IPD) game (Axelrod, 1984a; Sigmund, 2010). We show that these strategies can reduce the opportunity cost of verifying whether the action of their co-player was actually cooperative, and out-compete strategies that are always conditional, such as Tit-for-Tat. We argue that the opportunity cost of checking the action of the co-player is likely to be greater when the interaction is between people and intelligent artificial agents, because of the reduced transparency of the agent.
Differences in triglyceride levels before and after whey protein intervention in field workers exposed and unexposed to arsenic

Background: A work environment that is exposed to heavy metals, such as a coal mining environment, can change fat metabolism in the body. Changes in fat metabolism will lead to cardiovascular disease. Consumption of dairy products, e.g. whey protein, can reduce the risk of metabolic disorders and cardiovascular disease. Objectives: To test and analyze the differences in triglyceride levels before and after whey protein intervention to field workers with different working conditions. Materials and Methods: This experimental research with pretest and posttest was conducted on field workers at PT Bukit Asam Tbk. Tarahan Port Unit, Lampung as an Arsenic exposed group and PTPN VII Way Berulu Business Unit as an Arsenic unexposed group. Both groups received 24 grams of whey protein daily for 28 days. The triglyceride levels before and after the intervention were measured by laboratory analysis using the enzymatic calorimetry method. The data were analyzed using independent t-test, Mann Whitney test, and Wilcoxon test. Results: The average triglyceride levels increased by 50.48 ± 98.09 mg/dL in the exposed group and 16.78 ± 67.67 mg/dL in the unexposed group. There was a significant difference in triglyceride levels before and after the whey protein intervention in the two groups. Conclusions: The whey protein intervention increased the triglyceride level in the exposed group and decreased it in the
MPPI-VS: Sampling-Based Model Predictive Control Strategy for Constrained Image-Based and Position-Based Visual Servoing

In this paper, we open up new avenues for visual servoing systems built upon the Path Integral (PI) optimal control theory, in which the non-linear partial differential equation (PDE) can be transformed into an expectation over all possible trajectories using the Feynman-Kac (FK) lemma. More precisely, we propose an MPPI-VS control strategy, a real-time and inversion-free control strategy on the basis of sampling-based model predictive control (namely, Model Predictive Path Integral (MPPI) control) algorithm, for both image-based, 3D point, and position-based visual servoing techniques, taking into account the system constraints (such as visibility, 3D, and control constraints) and parametric uncertainties associated with the robot and camera models as well as measurement noise. Contrary to classical visual servoing control schemes, our control strategy directly utilizes the approximation of the interaction matrix, without the need for estimating the interaction matrix inversion or performing the pseudo-inversion. We validate the MPPI-VS control strategy as well as the classical control schemes on a 6-DoF Cartesian robot with an eye-in-hand camera based on the utilization of four points in the image plane as visual features. To better assess and demonstrate the robustness and potential advantages of our proposed control strategy compared to classical schemes, intensive simulations under various operating conditions are carried out and then discussed. The obtained results demonstrate the effectiveness and capability of the proposed scheme in coping easily with the system constraints, as well as its robustness in the presence of large errors in camera parameters and measurements.
Multiple Relay Nodes Selection Scheme using Exit Time Variation for Efficient Data Dissemination in VANET

Efficient Data dissemination in VANET is still the challenge because of variable speed of vehicles, road conditions, frequent fragmentation etc. In this article a selective forwarding data dissemination scheme using exit time differences in vehicles for highway lanes scenario is proposed that focuses on the solution of broadcast storm, less coverage, transmission delay and reliable data delivery. Our approach is selecting multiple forwarding nodes to increase coverage in less delay. In this article road lanes concept is used to identify the moving node direction. Redundant regions and zones technique in proposed approach is reducing the processing of parameters at significant extents. Simulation of proposed approach is done using NS2 and SUMO. Output of implementation is compared with unidirectional flooding, KB_Selective, and LT_Selective techniques. Result analysis shown that the proposed technique is much efficient and it increases the rate of coverage up to 23%. Also it reduces the delay up to 18% in data delivery ratio. This methodology also improves the performance of system by increasing the throughput and reducing the collision rate in comparison with other methods. Keywords—Broadcasting; disseminations; exit time; highway lanes; relay nodes; vehicle speed; vehicular ad hoc networks

LA LARVA DE HYLA URUGUAYA SCHMIDT, 1944 (ANURA: HYLIDAE), CON COMENTARIOS SOBRE SU BIOLOGÍA EN URUGUAY Y SU STATUS TAXONÓMICO

A B S T R A C T. o Hyla uruguaya is a poorly known species with controversial taxonomic status. Its finding in Uruguay has been sporadic. In the present work larval morphology, some aspects of reproductive biology, geographical distribution and ecology in Uruguay are addressed. The tadpole has a robust and elliptic body, lateral eyes, high fins, left spiracle, vent tube short and dextral, labial tooth row formula of [(1)(1-1)/(1-1)(2)], a single row of oral papillae with a dorsal gap and some submarginal subangular papillae. A spawn of 398 eggs of 1,3 mm diameter was obtained in the laboratory. The advertisement call, which can be sustained up to 13 min., consists of a series of multipulsed notes of 22 ms long, with a mean dominant frequency of 4146 Hz and a note repetition rate of 4,2 n 4,8 notes/s. The call was heard in the wild since late August, and tadpoles were found up to late February in ponds of open areas in hilly landscapes of NE, E y SE Uruguay. The results allow a reconsideration of the conservation status of the species in Uruguay. The relationship with the cryptic species Hyla pinima is discussed and based on larval characters taxonomic affinities with species of the ruber clade of Scinax are suggested.
Use of Organic Acids in Bamboo Fiber-Reinforced Polypropylene Composites: Mechanical Properties and Interfacial Morphology.

In obtaining wood polymer composites (WPCs), a weak interfacial bonding can cause problems during the processing and affect the mechanical properties of the resulting composites. A coupling agent (CA) is commonly used to solving this limitation. To improve the interfacial bonding between bamboo fiber (BF) and a polypropylene matrix, the effect of three organic acids on the mechanical properties and interfacial morphology were investigated. The BF/PP composites were prepared in five families: the first without CA, the second using a maleic anhydride-grafted polypropylene coupling agent, and the third, fourth, and fifth families with the addition of organic acids (OA) tricarboxylic acid (TRIA), hexadecanoic acid (HEXA), and dodecanoic acid (DODA), respectively. The use of OA in BF/PP improved the interfacial adhesion with the PP matrix, and it results in better mechanical performance than composites without CA. Composites coupled with MAPP, TRIA, DODA, and HEXA showed an increase in Young’s modulus of about 26%, 23%, 15%, and 16% respectively compared to the composite without CA incorporation. In tensile strength, the increase in composites with CA was about 190%, while in the flexural modulus, the coupled composites showed higher values, and the increase was more in composites with TRIA: about 46%. The improvement caused by tricarboxylic acid was similar to that promoted by the addition of maleic anhydride-grafted polypropylene (MAPP).

EFFECTS OF DISCOREA DUMENTORUM TUBER SUPPLEMENTED DIET ON PLASMA LIPID PROFILE AND GLUCOSE LEVEL OF HYPERCHOLESTEROLEMIC RATS

This study was designed to investigate the effects of Discorea dumentorum tuber supplemented diet on the plasma lipid profile and glucose level of hypercholesterolemic rats. Thirty two male albino rats (Rattus novergicus) were divided into two groups control and Group1. Rats in control received cholesterol-free diet. Group 1 (hyper control) fed 1% cholesterol + 20% fat diet. On establishing hypercholesterolemia, Group1 rats were sub-divided into three groups (1,2,3), with seven rats in each. Groups 2 and 3 diets were supplemented with white bitter yam and yellow bitter yam flour respectively, while Group1 rats were maintained on the hypercholesterolemic diet. They were fed for four weeks, after which the blood samples were collected via cardiac puncture. Plasma lipid profile (Triglyceride (TG), High density lipoprotein (HDL), Low density lipoprotein (LDL), Total cholesterol (TC) and Glucose level were determined. The result showed significantly higher (p≤ 0.05) levels of plasma TC, LDL, nonsignificant increase in TG, HDL remained unchanged and LDL/HDL ratio was higher in the hyper control rats than the control (p≤ 0.05) while feeding with white and yellow bitter yam (Discorea dumentorum) tuber supplement caused a decrease in the levels of TC, LDL and LDL/HDL ratio when compared with the hypercontrol group (p≤ 0.05). White Discorea dumentorum tuber supplement caused nonsignificant increase level of TG and nonsignificant decrease level of HDL in group2 when compared with the hypercontrol group (p≤ 0.05). Yellow Discorea dumentorum tuber supplement caused a significant increase in the level of TG and significant decrease (p≤ 0.05) in the level of HDL in group3 when compared with the hypercontrol group. Glucose level in hypercontrol rats i.e (group1) was significantly higher compared with the control and on
Competition between hydrogen bonds and halogen bonds: a structural study

The competition and balance between intermolecular hydrogen bonds (HBs) and halogen bonds (XBs) were explored by co-crystallizing tetra-functionalized (2 × HB (–OH) and 2 × XB (–CC–I)) molecules, trans-1,4-bis(iodoethynyl)cyclohexane-1,4-diol (D1) and cis-1,4-bis(iodoethynyl)cyclohexane-1,4-diol (D2), with six ditopic nitrogen based acceptor molecules. The crystal structures of both D1 and D2 showed non-covalent interactions between HB/XB donors and available acceptor sites (oxygen/triple bond/negative region of iodine). In three co-crystals of D1 the HB and XB donors act in similar ways as both activated iodine and hydroxyl hydrogen bind to the nitrogen acceptors in the solid state. In contrast, in a co-crystal of D2, a geometric isomer of D1, there were only hydrogen bonds to the co-former and the halogen-bond donor interacted with the hydroxyl oxygen atoms of D2. A stronger tendency for linear XB interactions (as well as greater van der Waals radii reduction) was observed with nitrogen atoms as acceptors (average reduction = 21%) compared to those involving an oxygen atom as an acceptor (average reduction = 16%). A control molecule, trans-1,4-diethynylcyclohexane-1,4-diol (D3), which has only HB donors (–OH and –CC–H) was also examined to get a better understanding of the balance between XB and HB intercations. The ethynyl hydrogen atom did not form hydrogen bonds to the nitrogen atoms in acceptors, and only O–H⋯N and –CC–H⋯O hydrogen bonds were observed in these structures.
Agglomeration Mechanism and a Protective Role of Al2O3 for Prolonged Cycle Life of Si Anode in Lithium-Ion Batteries

Si, the high-capacity anode for Li-ion battery (LIB), has intrinsic 300% volume changes limiting its commercial application. The volume change leads to particle pulverization that results in loss of electrical contacts. Various nanostructures are proposed to avoid the pulverization, but the commercialization is still a distant future. Recently, Al2O3 has demonstrated its ability to enhance electrochemical cycling performance. However, a comprehensive mechanistic role of the Al2O3 has not been well-understood. Here, we have combined electrochemical and chemical agitation tests to propose two novel mechanisms: Si agglomeration and a protective role of the Al2O3. LiPF6, the common Li salt of the LIB electrolyte, decomposes and forms HF that etches the native oxide layer then forms a labile Si–H surface. Because of the labile Si–H surfaces, the Si particles agglomerate during the volume changes. The Si agglomeration has a detrimental effect on the cycling performance associated with the loss of electrical con.
Synthesis of fluorine- doped silica-coating by fluorosilane nanofluid to ultrahydrophobic and ultraoleophobic surface

Liquid repellency treatment has many applications in various sectors including oil and gas reservoirs and self-cleaning surfaces. In this study, effect of silica, fluorine-doped silica and fluorine-doped silica-coating by fluorosilane nanofluid on ultrahydrophobic and ultraoleophobic surface of carbonate and sandstone rock were investigated. The nanoparticles were synthesized by sol-gel method and characterized using XRD, FTIR, FESEM and DLS and nanofluid was prepared. F–SiO2–F nanoparticle was adsorbed on surface of rocks and confirmed by FESEM and EDXA. Effect of nanofluid on wettability was investigated by measuring contact angles of water, crude oil, condensate, n-decane and ethylene glycol in air and stability of ultrahydrophobic and ultraoleophobic was investigated. Results show that nanofluid (0.05 wt% of nanoparticle) changes contact angle from strongly liquid-wet to strongly gas-wet in all systems. The original contact angle of water, crude oil, condensate, n-decane and ethylene glycol were 37.95°, 0°, 0°, 0° and 0° for carbonate rock and 40.30°, 0°, 0°, 0° and 0° for sandstone rock which altered to 146.47°, 145.59°, 138.24°, 139.06° and 146.52° for carbonate rock and 160.01°, 151.40°, 131.85°, 140.27° and 151.70° for sandstone rock after treatment. The ultraoleophobic and ultrahydrophobic stability were >48 h and 120 min.
Validating a Single-Particle ICP-MS Method to Measure Nanoparticles in Human Whole Blood for Nanotoxicology

ABSTRACT With the rising use of nanomaterials in everyday objects, an uptake of those materials by humans is very likely. To assess their effect on the body, reliable detection of nanoparticles even in very low amounts in human blood becomes increasingly important. Single-particle (SP) inductively coupled plasma–mass spectrometry (ICP-MS) is a fast and reliable method for counting and sizing particles at lowest concentrations, while simultaneously distinguishing between dissolved and particulate analytes. For the first time to our knowledge, a dedicated method validation approach for silver and gold nanoparticle analysis in human whole blood has been performed. With only little sample preparation, trueness expressed as bias with values below or equal to 5% and imprecision values below 6% for particle size as well as an effective limit of detection of around 20 nm are possible. The concentration working range throughout all measured samples was in the nanogram per liter range, making SP-ICP-MS a powerful tool in future nanotoxicological applications and trace analysis of nanoparticles.

Twelve concrete cubes of dimension 150 mm ×150 mm × 150 mm containing 0%, 0.25%, 0.50% and 1.0% of polyethylene fibres were cast and tested per BS 1881-part 116: 1983 to determine the compressive strength. Twelve concrete prisms measuring 100 mm×100 mm×300 mm containing 0%, 0.25%, flexural of N/mm fibre concrete concrete compressive increase is 3% for the 0.25% fibre concrete, 14% for the 0.5% fibre concrete, and 27% for the 1.0% fibre concrete specimen. The polyethylene fibres therefore have a generally positive effect on the flexural strength of concrete.
Novel mechanisms of endoderm and mesoderm formation

The formation of endoderm and mesoderm during gastrulation is well studied; however, the gastrulation lineage tree is still not solved. Using a dual knock-in reporter mESCs line, we demonstrated that Foxa2+ progenitors form anterior definitive endoderm (DE), while T+ progenitors give rise to mesoderm, axial mesoderm and posterior DE. We uncovered that DE is formed via a novel epithelial-to-epithelial transition and further identified that miR-335 fine-tunes transcription factor gradients in the endoderm and promotes mesendoderm lineage segregation.
