DCGNN: a single-stage 3D object detection network based on density clustering and graph neural network
Authors: Xiong Shimin , Li Bin , Zhu Shiao 
Published: December 2022

AbstractCurrently, single-stage point-based 3D object detection network remains underexplored. Many approaches worked on point cloud space without optimization and failed to capture the relationships among neighboring point sets. In this paper, we propose DCGNN, a novel single-stage 3D object detection network based on density clustering and graph neural networks. DCGNN utilizes density clustering ball query to partition the point cloud space and exploits local and global relationships by graph neural networks. Density clustering ball query optimizes the point cloud space partitioned by the original ball query approach to ensure the key point sets containing more detailed features of objects. Graph neural networks are very suitable for exploiting relationships among points and point sets. Additionally, as a single-stage 3D object detection network, DCGNN achieved fast inference speed. We evaluate our DCGNN on the KITTI dataset. Compared with the state-of-the-art approaches, the proposed DCGNN achieved better balance between detection performance and inference time.

Abstract
At Liang Bua, the type site of Homo floresiensis on the Indonesian island of Flores, the stone artefact assemblages are dominated by two raw materials, qualitatively classified as chert and silicified tuff in previous studies. Field observations describe both stone types as locally abundant and of good flaking quality, but no systematic analysis has yet been carried out to characterise their nature. In this study, we conducted the first geological, mechanical, and quantitative assessment of these two raw materials using a suite of analytical approaches. Our results show that the two stone types are mineralogically alike in composition and derive from fossiliferous limestone that had undergone diagenetic silica replacement, but they clearly differ from one another geochemically. Therefore, the ‘chert’ and ‘silicified tuff’ categories used in previous studies are more aptly described as silica-dominated (i.e., SiO2-dominated) nodular chert and iron-rich (i.e., Fe2O3-rich) nodular chert, respectively. We discuss the implications of our results on the shift in raw material utilisation patterns at Liang Bua that occurred after ~ 46 ka and coincided with the arrival of Homo sapiens at the site.
Simple and Ultrahigh Efficient Superhydrophilic Polydopamine-coated TiO2 Cotton for Oil–water Separation
Authors: Zhong Xin , Guo Zhiguang 
Published: December 2022

AbstractOil–water mixing has brought many problems to a society, and it is of great significance to develop a simple, convenient, efficient, and durable separation material to solve the problem of oil–water mixing. In this paper, modified cottons were successfully prepared using polydopamine as the in situ mineralization site of TiO2 nanoparticles combined with synergistic crosslinking with KH550. A large number of hydrophilic groups endowed the cotton with superhydrophilic ability, which greatly shortened its water spreading time. The prepared modified cotton could be successfully separated from oil and water, and still had a separation efficiency of 99.999% after 50 cycles. In addition, after 24 h immersion in 1 M HCl, NaOH, and NaCl solutions and 50 abrasion experiments, the modified cotton showed excellent oil–water separation ability, and the separation efficiency was above 99.990%. Successfully provided a simple preparation method to prepare high-efficiency and clean cottons for oil–water separation.

Published: December 2022

Abstract
Most children in foster care have poor health outcomes and high health care utilization. Health complexity influences health care utilization as well foster care placement. Health care utilization studies among children in foster care have not accounted for health complexity status and foster placement. A 7-year retrospective study linked Colorado child welfare and Medicaid administrative data for 30,164 Medicaid-enrolled children, up to 23 years old, who differed by initial foster care entry, to examine primary care and behavioral health (BH) utilization patterns from 2014 to 2021. Children entering care were matched with replacement to non-foster peers by age, sex, Medicaid enrollment patterns, managed care status, family income, and health complexity. We calculated weighted monthly average percentages of children with primary care and BH utilization by foster care entry, health complexity, sex, and age over 25 months relative to the month of foster care entry for the foster cohort or the reference month for non-foster peers. Children in the foster cohort had lower primary care but higher BH utilization relative to non-foster peers prior to the reference month. Primary care and BH use increased among children in foster care during and 12 months after the reference month, unlike matched comparisons. Primary care and BH utilization increased by health complexity but differed by foster care status and time. Foster care entry and health complexity produced distinct patterns of primary care and BH utilization. Given higher utilization among children in foster care, future investigation should explore health care quality and delivery factors.

Published: December 2022

AbstractBorehole water has been the main source of drinking water for the communities living within the Nnewi metropolis. The quality of this borehole water has been significantly affected by the presence of unlined waste dumpsites which release leachates. The present study investigated the physicochemical characteristics and quality of borehole water located around the environment of the unlined dumpsite in Nnewi. In this study, thirty-two (32) borehole water samples were collected from around the dumpsite (16) and control (16) areas in wet and dry seasons. The levels of the physicochemical parameters were determined using the American Public Health Association (APHA) standard methods. The quality of the borehole water was compared with World Health Organization (WHO) permissible drinking water limits. The pollution index (PI) and water quality index (WQI) of the borehole water were also evaluated. The results also showed that only the nitrite values in the dumpsite area for both seasons were above the WHO drinking water limits. The summation of the pollution indices were above the critical value of 1 in both seasons for the study areas. The WQI revealed that the water samples were heavily polluted with the most polluted being the dumpsite area in both seasons. The results revealed that the underground water in the dumpsite area was contaminated through the uncontrolled release of leachates from dumpsite. The contamination from the control area may not be related to the dumpsite but was linked to irregular waste disposal sites, wastewater infiltration and run-off from farmlands. The borehole water samples was not good for drinking and domestic purposes without proper treatment.

Published: December 2022

AbstractSurfactants represent a large group of industrial relevant substances and can be generated chemically, but also biologically. Important microbial producers are severalPseudomonasspecies, mainly known for their ability to produce rhamnolipids. For safety reasons, recombinantPseudomonas putidais preferred for heterologous production of rhamnolipids as well as its precursor 3-(3-hydroxyalkanoyloxy) alkanoic acid (HAA), which is a promising platform substance. The surface-active properties of HAA combined with classical submerged aeration cause strong foam formation making biotechnological production in stirred tank bioreactors challenging. Therefore, a foam-free bioprocess for HAA production was developed in this study. The combination of headspace aeration, overpressure up to 8 bar, and temperature reduction prevented oxygen limitation, shortened process time, and enhanced the maximum HAA concentration to 1.71 g l− 1with a space-time yield of 0.08 g l− 1 h− 1.Graphical Abstract
Examples of shifting development pathways: lessons on how to enable broader, deeper, and faster climate action
Authors: Winkler Harald , Lecocq Franck , Lofgren Hans , Vilariño Maria Virginia , Kartha Sivan , Portugal-Pereira Joana 
Published: December 2022

AbstractTo respond to the climate crisis, we need to accelerate system transformations at a pace, scale, and breadth not seen before. This means that it is urgent to shift development pathways towards net zero greenhouse gas emissions, even while progressing towards other sustainable development objectives. This paper argues that accelerated mitigation can not only benefit from policies that are outside the domain of conventional emission-focused mitigation policies but require such policies. We refer to this process as shifting development pathways towards sustainability. Here, we explore what enabling conditions make such shifts possible. We develop a framework to select examples of shifts — in realms such as educational access, housing access, fiscal arrangements, and institutional reform. We analyse them against key enablers. Our findings suggest that countries could learn from what has worked elsewhere, though context matters. Some enablers are more widely applicable, including finance, long-term vision, and focus on sustainable development objectives. Multiple enablers, integrated policy packages, and involvement of a broad range of actors help achieve multiple objectives. Some enablers may yield results in the near term, while others take time to yield results. Based on our analysis, we suggest that climate mitigation requires an “all of economy, all of society” approach.

The psychological impact of the Metaverse
Authors: Henz Patrick 
Published: December 2022

AbstractThe Metaverse is no revolution, but another step in the evolution of the internet. Today we can observe various 3D virtual worlds with different focuses and purposes, like meeting spaces, education, or classic gaming. Most of these applications run on computer or smart phone, some of these 3D platforms support virtual reality glasses, or even further wearables like haptic gloves. Nevertheless, the general interconnection of these platforms is still lacking. Due to this, user information, including avatars, cannot be reused for other applications. Even if the research company Gartner predicts that already “by 2026, 25% of the people will spend at least 1 h a day in the Metaverse for work, shopping, education, social and/or entertainment,” the vision still did not manifest yet. This gives society and academia time to start a productive discussion. The article wants to support this ambition by first discussing a potential definition of what the Metaverse will be, including different types for different purposes. After that this, the text predicts the arrival, including required circumstances, then later the expected psychologic impact of the expected scenarios on the regular users. As human psychology depends on experience, environment and, of course, the contact with other humans, such a scenario will have a relevant impact, up to a different understanding of reality, as people frictionless move from physical to virtual world, and even interact on complete different virtual worlds. Existing articles regarding the connections between online (like video games and social media) and offline behavior focused on particular cohorts. As the Metaverse will change work and private life, wide parts of society are voluntary and non-voluntary affected, which limits the possibility to transfer the insights from earlier scenarios to this topic. This article focuses on shifted Socialization, Roles, Perception, and the relating Humanization of Artificial Intelligence, as it enables the algorithm, consciously or subconsciously, to influence the human mind.

AbstractThe accurate annotation of transcription start sites (TSSs) and their usage are critical for the mechanistic understanding of gene regulation in different biological contexts. To fulfill this, specific high-throughput experimental technologies have been developed to capture TSSs in a genome-wide manner, and various computational tools have also been developed for in silico prediction of TSSs solely based on genomic sequences. Most of these computational tools cast the problem as a binary classification task on a balanced dataset, thus resulting in drastic false positive predictions when applied on the genome scale. Here, we present DeeReCT-TSS, a deep learning-based method that is capable of identifying TSSs across the whole genome based on both DNA sequence and conventional RNA sequencing data. We show that by effectively incorporating these two sources of information, DeeReCT-TSS significantly outperforms other solely sequence-based methods on the precise annotation of TSSs used in different cell types. Furthermore, we develop a meta-learning-based extension for simultaneous TSS annotations on 10 cell types, which enables the identification of cell type-specific TSSs. Finally, we demonstrate the high precision of DeeReCT-TSS on two independent datasets by correlating our predicted TSSs with experimentally defined TSS chromatin states. The source code for DeeReCT-TSS is available at https://github.com/JoshuaChou2018/DeeReCT-TSS_release and https://ngdc.cncb.ac.cn/biocode/tools/BT007316.
Self-Narrative, Affective Identification, and Personal Well-Being
Authors: CHENG KATHERINE CHIEH-LING 
Published: December 2022

AbstractThe narrative view of personhood suggests that we as persons are constituted by self-narratives. Self-narratives support not only the sense of personal persistence but also agency. However, it is rarely discussed how self-narratives promote or hinder personal well-being. This paper aims to explore what a healthy self-narrative looks like. By reframing a famous debate between Strawson and Schechtman about narrative personhood, I argue that self-narratives can hinder our personal well-being when affective identification leads to inflexible self-images, illustrated with the examples of imposter syndrome and rationalization. Furthermore, I explore how having a healthy self-narrative is not about disengaging from one's personal past and future, but about fostering affective identification in ways that allow flexible self-images.
A generalized Sylvester–Gallai-type theorem for quadratic polynomials
Authors: Peleg Shir , Shpilka Amir 
Published: December 2022

AbstractIn this work, we prove a version of the Sylvester–Gallai theorem for quadratic polynomials that takes us one step closer to obtaining a deterministic polynomial time algorithm for testing zeroness of$\Sigma ^{[3]}\Pi \Sigma \Pi ^{[2]}$circuits. Specifically, we prove that, if a finite set of irreducible quadratic polynomials${\mathcal {Q}}$satisfies that for every two polynomials$Q_1,Q_2\in {\mathcal {Q}}$there is a subset${\mathcal {K}}\subset {\mathcal {Q}}$such that$Q_1,Q_2 \notin {\mathcal {K}}$and whenever$Q_1$and$Q_2$vanish, then$\prod _{i\in {\mathcal {K}}} Q_i$vanishes, then the linear span of the polynomials in${\mathcal {Q}}$has dimension$O(1)$. This extends the earlier result [21] that holds for the case$|{\mathcal {K}}| = 1$.
The Nature of a Constant of Nature: The Case of G
Authors: Jacobs Caspar 
Published: December 2022

AbstractPhysics presents us with a symphony of natural constants: $G$, ℏ, $c$, and so forth. Up to this point, constants have received comparatively little philosophical attention. In this article, I provide an account of dimensionful constants, in particular the gravitational constant. I propose that they represent interquantity structure in the form of relations between quantities with different dimensions. I use this account of $G$ to settle a debate over whether mass scalings are symmetries of Newtonian gravitation. I argue that they are not, but only if we interpret mass anti-quidditistically. This is analogous to anti-haecceitism in the presence of spacetime symmetries.
Authority, Plurality, and Anarchist Scepticism
Authors: Fives Allyn 
Published: December 2022

AbstractAccording to A. John Simmons's anarchist scepticism, there is no duty to obey the law as things stand, as legal obligations have legitimacy only when voluntarily incurred by most or many citizens. However, an alternative, pluralist position is suggested by Simmons's sensitivity to the diversity of reasons and to the possibility of unresolved conflict. It shows that the grounds of legitimate authority are plural, and include distributive justice. Also, even voluntarily incurred obligations can be defeated by conflicting reasons, as when we are duty bound to an unjust regime.

AbstractEocene–Oligocene magmatic rocks are well exposed in the region south of Birjand, eastern Iran. The ages, geochemistry and petrogenesis of these rocks are important to understand eastern Iran’s magmatic and geodynamic history during the Cenozoic. Detailed field investigations show that numerous intrusive, intermediate to felsic units are intruded into a thick sequence of Eocene–Oligocene lava flows and their accompanying pyroclastic rocks. The volcanic rocks are mainly basaltic andesitic to rhyolitic, whereas intrusive rocks are characterized by dioritic to granitic composition. Previously compiled U–Pb geochronological data indicate that Eocene–Oligocene magmatism in eastern Iran formed continuously from ∼46 Ma to ∼25 Ma. Our new zircon U–Pb data reveal crystallization ages of 43.6 ± 0.4 Ma to 39.5 ± 0.6 Ma, consistent with the upper end of this age range. Geochemically, the igneous rocks have high-K calc-alkaline to shoshonitic signatures. Rare-earth and trace element patterns show enrichment in LREEs, K, Rb, Cs, Pb, Th and U and depletion in HFSEs such as Nb, Zr and Ti, typical of a subduction-related environment.87Sr/86Sr(i)and ϵNd(i)values range from 0.7051 to 0.7064 and −0.1 to +0.2, respectively. We postulate that the Cretaceous northeastward subduction of the Neo-Tethyan oceanic lithosphere underneath the Iranian Plateau caused sub-continental lithospheric mantle (SCLM) metasomatism by slab-derived fluid components. Subsequently, slab roll-back of the Neo-Tethyan oceanic lithosphere associated with asthenospheric upwelling led to lithospheric thinning and melting of the metasomatized SCLM. The resulting parental magmas probably interacted with upper continental crust during magma ascent to form Eocene–Oligocene magmatism in eastern Iran.

AbstractObjectiveThis study aimed to examine the association between nasal septal deviation and antrochoanal polyp.MethodsThis was a retrospective review of medical records and imaging of patients who underwent endoscopic sino-nasal surgery for antrochoanal polyp.ResultsForty-eight patients operated on for antrochoanal polyp between 2009 and 2019 were eligible for the study. The median age was 32 years, and 52.1 per cent were male. Antrochoanal polyp was diagnosed equally in the right and left nasal cavities. Septal deviation was present in 77 per cent of such cases. In 44 per cent of septal deviation cases, the antrochoanal polyp was ipsilateral to the deviation, which was not statistically significant. The type of deviation according to the Mladina classification was not correlated with the laterality of septal deviation and antrochoanal polyp.ConclusionThe laterality of the septal deviation was not found to be correlated with that of the antrochoanal polyp. Therefore, performing routine septoplasty during antrochoanal polyp surgery is unnecessary unless the deviation interferes with the complete extraction of the polyp.
Social Solidarity: A Note on the Health of the Profession
Authors: Kariel Henry S. 
Published: December 2022

Since I have been unable to find a formula which might justify simply publishing the welter of mixed responses I have received, I thought I might at least provide those who responded to my inquiry (84.2%) with a basis for assessing our common enterprise.The profession would appear to be inordinately healthy. There is certainly an abundance of self-restraint, decorum, ingenuity, and determination not to be taken in by mischievous gimmicks. Nelson Polsby was not alone in seeing that the survey was rigged to fail since it would publicize work which, as he put it, ought to enjoy a little benign neglect. A preponderant majority of respondents managed to be evasive by a display of wit and cunning which surely excused the fact that they had resolved to hurt no one. Those who were not masterfully evasive met the issue head-on. In what has suddenly become an especially engaging note, Clinton Rossiter wrote a week before his death:I would like to oblige, but the overpowering fact is that I would hurt the feelings of a very good friend were I to single out the article or book published during the last quarter century that seems to me to “have received too much attention.” I have been a witness to and target of just a little too much nastiness in our profession in the past couple of years, and I hope you will excuse me from adding, however tactfully, to the sum total of nastiness that seems to pervade this world.
San Francisco in Five Hundred Words or Less

Published: December 2022

The only salutary consequence of the failure of the APSA dues increase to attract fifty percent plus one of the voters is that those who attend the San Francisco Convention will be spared a long essay on the pleasures of the flesh—eating and sightseeing—in the convention city. That essay would have afforded me room to describe my thirty-five year love affair with this city and to detail why I believe it to be the most exciting and satisfying forty-two square urban miles on earth. Since I lack the space, you will have to make do with a more succinct statement.First things first, let's consider food: You can do advanced research to prepare yourself for the convention week—lest you “waste” one lunch or dinner on “ordinary” fare—or you can follow your fancy, get yourself into the right area of the City (too humble for all caps, but surely not lower case) and look around for the great buys (they exist aplenty).For the research oriented: The indispensable tool is Jack Shelton's Private Guide. This monthly newsletter, because it is monthly, is the only really reliable guide (Shelton's identity is unknown to the restauranteurs, he bases a judgment on no fewer than three visits, he knows food, his tastes generally agree with mine). I would behoove the Association to have a file of Shelton's newsletters available for those who wish to plan their day.
