description: The Turing machine, as it was presented by Turing himself, models the calculations done by a person. This means that we can compute whatever any Turing machine can compute, and therefore we are Turing complete. The question addressed here is why, Why are we Turing complete?
Being Turing complete also means that somehow our brain implements the function that a universal Turing machine implements. The point is that evolution achieved Turing completeness, and then the explanation should be evolutionary, but our explanation is mathematical. The trick is to introduce a mathematical theory of problems, under the basic assumption that solving more problems provides more survival opportunities.

So we build a problem theory by fusing set and computing theories. Then we construct a series of resolvers, where each resolver is defined by its computing capacity, that exhibits the following property: all problems solved by a resolver are also solved by the next resolver in the series if certain condition is satisfied. The last of the conditions is to be Turing complete.

This series defines a resolvers hierarchy that could be seen as a framework for the evolution of cognition. Then the answer to our question would be: to solve most problems. By the way, the problem theory defines adaptation, perception, and learning, and it shows that there are just three ways to resolve any problem: routine, trial, and analogy. And, most importantly, this theory demonstrates how problems can be used to found mathematics and computing on biology.

description: The aim of this study was to determine the anti-tumour activity of tanshinone IIA in SKOV3 cells. Results suggested that tanshinone IIA could significantly inhibit (IC50 value  =  19.6 μM) the proliferation and induce apoptosis of SKOV3 cells as demonstrated by flow cytometry analysis. In addition, tanshinone IIA treatment induced G2/M phase cell cycle arrest in SKOV3 cells. The results of Western blotting indicated that tanshinone IIA can suppress the expression of anti-apoptotic protein Bcl-2, increase (0.28 vs. 0.62) the expression of pro-apoptotic protein Bax (0.83 vs. 0.24) in SKOV3 cells. It can be concluded that the tanshinone IIA may be a possible therapeutic candidate having cytotoxic and anti-tumour potential.

description: Objective: To compare the sensitivity of current field triage practices for identifying high-risk trauma patients to strict guideline adherence, including changes in triage specificity, ambulance transport patterns, and trauma center volumes. Methods: This was a pre-planned secondary analysis of an out-of-hospital prospective cohort of injured children and adults transported by 44 EMS agencies to 28 trauma and non-trauma hospitals in 7 Northwest U.S. counties from January 1, 2011 through December 31, 2011. Outcomes included Injury Severity Score (ISS) ≥16 (primary) and early critical resource use. Strict adherence of the triage guidelines was based on evidence in the EMS chart for patients meeting any current field triage criteria, calculated with and without strict interpretation of the age criterion (<15 or >55 years). Due to the probability sampling nature of the cohort, strata and weights were included in all analyses. Results: 17,633 injured patients were transported by EMS (weighted to represent 53,487 transported patients), including 3.1% with ISS ≥16 and 1.7% requiring early critical resources. Field triage sensitivity for identifying patients with ISS ≥16 increased from the current 66.2% (95% CI 60.2–71.7%) to 87.3% (95% CI 81.9–91.2%) for strict adherence without age and to 91.0% (95% CI 86.4–94.2%) for strict adherence with age. Specificity decreased with increasing adherence, from 87.8% (current) to 47.6% (strict adherence without age) and 35.8% (strict adherence with age). Areas under the curve (AUC) were 0.78, 0.73, and 0.72, respectively. Results were similar for patients requiring early critical resources. We estimate the number of triage-positive patients transported each year by EMS to an individual major trauma center (on average) to increase from 1,331 (current) to 5,139 (strict adherence without age) and to 6,256 (strict adherence with age). Conclusions: The low sensitivity of current triage practices would be expected to improve with strict adherence to current triage guidelines, with a commensurate decrease in triage specificity and an increase in the number of triage-positive patients transported to major trauma centers.

description: In order to grasp and transport an object, grip and load forces must be scaled according to the object’s properties (such as weight). To select the appropriate grip and load forces, the object weight is estimated based on experience or, in the case of robots, usually by use of image recognition. We propose a new approach that makes a robot’s weight estimation less dependent on prior learning and, thereby, allows it to successfully grasp a wider variety of objects. This study evaluates whether it is feasible to predict an object’s weight class in a replacement task based on the time series of upper body angles of the active arm or on object velocity profiles. Furthermore, we wanted to investigate how prediction accuracy is affected by (i) the length of the time series and (ii) different cross-validation (CV) procedures. To this end, we recorded and analyzed the movement kinematics of 12 participants during a replacement task. The participants' kinematics were recorded by an optical motion tracking system while transporting an object, 80 times in total from varying starting positions to a predefined end position on a table. The object’s weight was modified (made lighter and heavier) without changing the object’s visual appearance. Throughout the experiment, the object’s weight (light/heavy) was randomly changed without the participant’s knowledge. To predict the object’s weight class, we used a discrete cosine transform to smooth and compress the time series and a support vector machine for supervised learning from the achieved discrete cosine transform parameters. Results showed good prediction accuracy (up to 95%, depending on the CV procedure and the length of the time series). Even at the beginning of a movement (after only 300 ms), we were able to predict the object weight reliably (within a classification rate of 88-94%).

Syntax Evolution: Problems and Recursion

description: Why did only we humans evolve Turing completeness? Turing completeness is the maximum computing power, and we are Turing complete because we can calculate whatever any Turing machine can compute. Thus we can learn any natural or artificial language, and it seems that no other species can, so we are the only Turing complete species. The evolutionary advantage of Turing completeness is full problem solving, and not syntactic proficiency, but the expression of problems requires a syntax because separate words are not enough, and only our ancestors evolved a protolanguage, and then a syntax, and finally Turing completeness. Besides these results, the introduction of Turing completeness and problem solving to explain the evolution of syntax should help us to fit the evolution of language within the evolution of cognition, giving us some new clues to understand the elusive relation between language and thinking.

description: Sargassum muticum (Yendo) Fensholt is an invasive canopy-forming brown alga, expanding its presence from Northeast Asia to North America and Europe. The complete mitochondrial genome of S. muticum is characterized as a circular molecule of 34,720 bp. The overall AT content of S. muticum mitogenome is 63.41%. This mitogenome contains 65 genes typically found in brown algae, including 3 ribosomal RNA genes, 25 transfer RNA genes, 35 protein-coding genes, and 2 conserved open reading frames (ORFs). The gene order of mitogenome for S. muticum is identical to that for Sargassum horneri, Fucus vesiculosus and Desmarestia viridis. Phylogenetic analyses based on 35 protein-coding genes reveal that S. muticum has a close evolutionary relationship with S. horneri and a distant relationship with Dictyota dichotoma, supporting current taxonomic systems. The present investigation provides new molecular data for studies of S. muticum population diversity as well as comparative genomics in the Phaeophyceae.

description: This is an extract from the performance that was a result of the artistic research of Circus Sessions 2019 for which Michelle Man was principle investigator and facilitator. For this international Canadian Arts Council funded research and development project that brought together fourteen female artists from five different countries, Man took as a starting point notions of conviviality or 'convivencia' in artistic collaborative processes. The embodied research in Circus Sessions took as its foci positive receptivity, hospitality and fascination as creative tools in collective devising processes. This extract offers something of how these notions operate within in a collective in contemporary circus making.

description: The male sterility system shows tremendous value for the long-term utilization of hybrid crop breeding. In this study, a male sterile mutant, K305ms, was derived from the M3 progeny of maize (Zea mays L.) inbred line K305 exposed to 60Co-γ irradiation. Male sterile K305ms plants did not show any obvious differences from their sibling male fertile plants (K305F) during the vegetative stage, but failed to produce functional pollen at the reproductive stage. Microscopic observations determined that the dyads and tetrads from the pollen of K305ms plants developed abnormally, and subsequently the microspores were shriveled. Genetic analysis indicated that the male sterility of K305ms was controlled by a single recessive genic gene. Gene mapping showed that the responsible gene was located between two simple sequence repeat markers on chromosome 2L in a region of 10.3 cM, bnlg469b and bnlg1940, with genetic distances of 2.9 and 7.4 cM, respectively. According to the microscopic and mapping characteristics, our results showed that this gene was distinguishable from all other reported male sterile genes in maize, and it is temporarily designated as ms305. The linkage map in this study will provide a useful fundamental basis for molecular marker-assisted selection as well as for further map-based cloning of ms305.

description: Infinite-layer (IL) nickelates are an emerging class of superconductors, where the Ni$^{1+}$ valence state in a square planar NiO$_2$ coordination can only be reached via topotactic reduction of the perovskite phase. However, this topotactic soft chemistry with hydrogenous reagents is still at a stage of rapid development, and there is a number of open issues, especially considering the possibility of hydrogen incorporation. Here we study the time dependence of the topotactic transformation of LaNiO$_3$ to LaNiO$_2$ for powder samples with x-ray diffraction and gas extraction techniques. While the hydrogen content of the powder increases with time, neutron diffraction shows no negative scattering of hydrogen in the LaNiO$_2$ crystal lattice. The extra hydrogen appears to be confined to grain boundaries or secondary-phase precipitates. The average crystal structure, and possibly also the physical properties, of the primary LaNiO$_2$ phase are therefore not noticeably affected by hydrogen residues created by the topotactic transformation.

description: Background. The study investigated if intraoperative use of carmustine wafers, particularly in combination with Stupp regimen, is a viable and safe first-line treatment option of glioblastomas. Methods. Eighty-three consecutive adult patients (50 men; mean age 60 years) with newly diagnosed supratentorial primary glioblastomas that underwent surgical resection with intraoperative carmustine wafers implantation (n = 7.1 ± 1.7) were retrospectively studied. Results. The median overall survival (OS) was 15.8 months with 56 patients dying over the course of the study. There was no significant association between the number of implanted carmustine wafers and complication rates (four surgical site infections, one death). The OS was significantly longer in Stupp regimen patients (19.5 months) as compared with patients with other postoperative treatments (13 months; p = 0.002). In addition patients with eight or more implanted carmustine wafers survived longer (24.5 months) than patients with seven or less implanted wafers (13 months; p = 0.021). Finally, regardless of the number of carmustine wafers, median OS was significantly longer in patients with a subtotal or total resection (21.5 months) than in patients with a partial resection (13 months; p = 0.011). Conclusions. The intraoperative use of carmustine wafers in combination with Stupp regimen is a viable first-line treatment option of glioblastomas. The prognostic value of this treatment association should be evaluated in a multicenter trial, ideally in a randomized and placebo-controlled one.

description: To overcome multidrug resistance (MDR) in cancer chemotherapy with high efficiency and safety, a reduction-sensitive liposome (CL-R8-LP), which was co-modified with reduction-sensitive cleavable PEG and octaarginine (R8) to increase the tumor accumulation, cellular uptake and lysosome escape, was applied to co-encapsulate doxorubicin (DOX) and a P-glycoprotein (P-gp) inhibitor of verapamil (VER) in this study. The encapsulation efficiency (EE) of DOX and VER in the binary-drug loaded CL-R8-LP (DOX + VER) was about 95 and 70% (w/w), respectively. The uptake efficiencies, the cytotoxicity, and the apoptosis and necrosis-inducing efficiency of CL-R8-LP (DOX + VER) were much higher than those of DOX and the other control liposomes in MCF-7/ADR cells or tumor spheroids. Besides, CL-R8-LP (DOX + VER) was proven to be uptaken into MCF-7/ADR cells by clathrin-mediated and macropinocytosis-mediated endocytosis, followed by efficient lysosomal escape. In vivo, CL-R8-LP (DOX + VER) effectively inhibited the growth of MCF-7/ADR tumor and reduce the toxicity of DOX and VER, which could be ascribed to increased accumulation of drugs in drug-resistant tumor cells and reduced distribution in normal tissues. In summary, the co-delivery of chemotherapeutics and P-gp inhibitors by our reduction-sensitive liposome was a promising approach to overcome MDR, improve anti-tumor effect and reduce the toxicity of chemotherapy.

description: A CO2-switchable polymer surfactant was synthesized with acrylamide (AM) and 2-(dimethylamino)ethyl methacrylate (DMAEMA). The changes in conductivity, particle size, and ζ-potential were adopted to illustrate its switchability. The CMC of the surfactant was determined by the break point of the curve of surface tension versus concentration. An oil emulsion with 8 g/L surfactant almost reached the highest stability. The thermodynamic stability of the emulsion decreased sharply upon increase of the temperature. Adding an inorganic salt was hard to affect the emulsion stability because the surfactant is non-ionic. The emulsion could maintain its stability even if the concentration of NaCl was as high as 10 g/L. The emulsion could easily be broken by bubbling CO2. Its dehydration rate was 155 times faster than that without the presence of CO2, and the amount of residual oil in water was only 32.22 ppm, which displayed brilliant performance of de-emulsification.

description: We analyse the Klein-Gordon oscillator in a cosmic string space-time and study the effects stemming from the rotating frame and non-commutativity in momentum space. We show that the latter mimics a constant magnetic field, imparting physical interpretation to the setup. The field equation for the scalar field is solved via separations of variables, and we obtain quantization of energy and angular momentum. The space-time metric is non-degenerate as long as the particle is confined within a hard-wall, whose position depends on the rotation frame velocity and the string mass parameter. We investigate the energy quantization both for a finite hard-wall (numerical evaluation) and in the limit of an infinite hard-wall (analytical treatment). We stress the effect of non-commutativity upon the energy quantization in each case.

The spin-zero DKP-like oscillator is obtained from the Klein-Gordon Lagrangian with a non-standard prescription for the oscillator coupling. We find that the solutions of the time-independent radial equation with the non-zero non-commutativity parameter parallel to the string are related to the confluent hypergeometric function. We find the quantized energy eigenvalues of the non-commutative oscillator.

Friction Force Analysis of Simultaneous Buckling of Tubing and Rod Strings

Subjects: subject: 91406 Petroleum and Reservoir Engineering

description: It has recently been shown that the rod string is bent by the buckled tubing during pumping cycle (Vagapov 2016a). This means that the buckled sucker rod string moves inside a helically buckled tubing during pumping cycle. The simultaneous buckling of tubing and rod strings must have an effect on sucker rod/tubing wear between the pump and the neutral point. However, the normal contact force between the buckled tubing and buckled rod string and constraining casing has not yet been investigated. In this paper the normal contact forces and the maximum normal contact forces are determined.
The friction between the rod and tubing strings affects the shape of the surface dynamometer card and can cause significant changes in the maximum and minimum loads imposed at the polished rod. Obviously, the friction force due the simultaneous buckling is added to the conventional friction forces. The friction force due to simultaneous buckling is in many regards very similar to fluid load and it creates nearly the same type of the load on a polished rod at the surface. Unfortunately, it is impossible to distinguish between the friction forces and fluid load by the shape of the surface card. As a result, the friction can greatly increases the difficulty of interpreting what is happening downhole. If the pressure differential across the plunger is not known, the friction forces due to the simultaneous buckling may go unnoticed. In these wells the friction force can be confused with fluid load.

description: Essential functionality in the ICT (Information and Communication Technology) space draws from standards such as HTTP (IETF RFC 2616, Bluetooth (IEEE 802.15) and various telecommunication standards (4G, 5G). They have fuelled rapid growth of ICT sector in the last decades by ensuring interoperability and consistency in computing environment. Research shows that firms that backed ICT standards and participated in standards development, have emerged as industry innovators. Standards development thus clearly has benefits for participating companies as well as technology development and innovation in general. However, significant costs are also associated with development of standards and need to be better understood to support investment in standardization necessary for todays ICT environment. We present a conceptual model that considers the potential for market innovation across a standards lifecycle and efficiency from standardization work, to build a forward-looking decision model that can guide an organizations standards development activities. We investigate and formalize motivations that drive firms to participate in standardization, specifically, changes in market innovation. Our model can serve as a strategic decision framework to drive assessments of a firms participation in standards development. We test our model with a use case on an established access control approach that was standardized more than two decades ago, Role Based Access Control (RBAC) using historical data. The investigation of the case study shows that change in market innovation is a significant indicator of success in standards development and are viable criteria to model a firms decision to participate (or not to participate) in a specific area of standardization.

description: Polymorphisms in platelet receptor genes may influence platelet function. This study aimed to assess the impact of five polymorphisms of genes encoding platelet receptors on the risk of ischemic and bleeding events in ST-elevation myocardial infarction (STEMI) patients after percutaneous coronary intervention (PCI). 503 consecutive Chinese patients with STEMI after an uneventful PCI and exposed to standard dual antiplatelet therapy for 12 months were enrolled. Polymorphisms of platelet receptors, GPIa (ITGA2, 807C > T, rs1126643), GPVI (GP6, 13254T > C, rs1613662), PAR-1 (F2R, IVS-14A > T, rs168753) and P2Y12 (P2RY12, 34C > T, rs6785930 and H1/H2 haplotype, 52G > T, rs6809699) were detected by the ligase detection reaction. The follow-up period was 12 months. Overall, 34 (6.8%) ischemic events occurred and 46 (9.1%) major bleedings occurred. Multivariate Cox regression analysis showed the carriage of F2R rs168753 minor allele was an independent predictor of the composite ischemic events (HR 0.387, 95% CI 0.193–0.778, p = 0.008) after adjusted for established risk factors. Multivariate logistic regression model identified that carriage of P2RY12 rs6809699 minor allele (OR 2.71, 95% CI 1.298–5.659, p = 0.008) was an independent predictor of major bleedings. The associations were then validated in a second cohort of 483 STEMI patients. In STEMI patients after PCI, F2R rs168753 minor allele could significantly contribute to the risk of ischemic events, and P2RY12 rs6809699 minor allele could predict bleedings. The genetic testing of platelet receptors can be valuable in predicting adverse events in STEMI patients after PCI.

description: Pair programming has been highlighted as an active learning technique with several benefits to students, including increasing participation and improving outcomes, particularly for female computer science students. However, most of the literature highlights the effects of pair programming in introductory courses, where students have varied levels of prior programming experience and thus may experience related group issues. This work analyzes the effect of pair programming in an upper-level computer science course, where students have a more consistent background education, particularly in languages learned and best practices in coding. Secondly, the effect of remote pair programming on student outcomes is still an open question and one of increasing importance with the advent of Covid-19. This work utilized split sections with a control and treatment group in a large, public university. In addition to comparing pair programming to individual programming, results were analyzed by modality (remote vs. in person) and by gender, focusing on how pair programming benefits female computer science students in confidence, persistence in the major, and outcomes. We found that pair programming groups scored higher on assignments and exams, that remote pair programming groups performed as well as in person groups, and that female students increased their confidence in asking questions in class and scored 12\% higher in the course when utilizing pair programming.

description: A newly discovered Devonian ophiolite located in the Taoxinghu area of central Qiangtang on the Qinhai–Tibet Plateau is described. The ophiolite consists of gabbro and diabasic dikes, and invasive cumulate gabbros-leucogabbros. The ophiolite has undergone greenschist facies metamorphism and minor deformation. Dating of the metagabbro by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) zircon U–Pb techniques yielded a weighted mean age of 367.2 ± 3.3 Ma (Late Devonian). Whole-rock geochemical analyses show that the rocks belong to the tholeiite series, with weak depletion in light rare-earth elements (LREEs), almost no Eu anomalies, weak enrichment in large-ion lithophile elements (LILEs), depletion in Nb and Ta, and weak negative Hf and Ti anomalies. These characteristics are similar to those of back-arc basin basalts. Together, these characteristics suggest that the rocks of the Devonian ophiolite formed by ~30% partial melting of spinel lherzolite, which was enriched by interaction with aqueous fluids during the late-generation phases; there is no evidence of subduction-related melting. The Devonian ophiolite rocks in the Taoxinghu area were first discovered in the LongmuCo–Shuanghu–Lancang suture zone. Detailed geochemical analyses show that the rocks formed in a back-arc ocean basin environment, indicating that the LongmuCo–Shuanghu–Lancang suture zone in central Qiangtang represents a Late Devonian intra-oceanic subduction zone in the Palaeo–Tethys Ocean. The discovery of the central Qiangtang Devonian ophiolite provides essential data for understanding the evolutionary history of the Palaeo–Tethys Ocean, and for identifying and understanding the roles of the different tectonic units on the Qinghai–Tibet Plateau.

description: Various studies suggested that brain-derived neurotrophic factor (BDNF) gene polymorphisms contributed to the development of many neurological disorders. However, whether BDNF Val66Met polymorphism is associated with epilepsy remains controversial. In our study, we tried to investigate the effects of this functional polymorphism on the occurrence of temporal lobe epilepsy (TLE) and its clinical phenotypes. Case-control studies were employed to study the association between BDNF Val66Met polymorphism and TLE as well as its clinical phenotypes, and magnetic resonance imaging examinations and voxel-based morphometry analyses were carried out for further study. Our results showed that the frequency of Met allele was found to be lower in the temporal lobe epilepsy (TLE) patients compared with the control subjects (43.9% vs. 48.6%, P = 0.012, OR = 1.21, 95% CI = 1.04-1.41), and the frequency of Met66 allele carriers in the TLE with HS was significantly lower than those non-carriers (20.5% vs. 29.1%, P = 0.040). However, we failed to find the difference between different genotypes and hippocampal asymmetry. Our findings suggested that BDNF Val66Met polymorphism might be correlated with epileptogenesis, and Met66 allele might play a protective role against the occurrence of TLE.

description: The Advancing Data Justice Research and Practice (ADJRP) project aims to widen the lens of current thinking around data justice and to provide actionable resources that will help policymakers, practitioners, and impacted communities gain a broader understanding of what equitable, freedom-promoting, and rights-sustaining data collection, governance, and use should look like in increasingly dynamic and global data innovation ecosystems. In this integrated literature review we hope to lay the conceptual groundwork needed to support this aspiration. The introduction motivates the broadening of data justice that is undertaken by the literature review which follows. First, we address how certain limitations of the current study of data justice drive the need for a re-location of data justice research and practice. We map out the strengths and shortcomings of the contemporary state of the art and then elaborate on the challenges faced by our own effort to broaden the data justice perspective in the decolonial context. The body of the literature review covers seven thematic areas. For each theme, the ADJRP team has systematically collected and analysed key texts in order to tell the critical empirical story of how existing social structures and power dynamics present challenges to data justice and related justice fields. In each case, this critical empirical story is also supplemented by the transformational story of how activists, policymakers, and academics are challenging longstanding structures of inequity to advance social justice in data innovation ecosystems and adjacent areas of technological practice.

description: The idea of "data justice" is of recent academic vintage. It has arisen over the past decade in Anglo-European research institutions as an attempt to bring together a critique of the power dynamics that underlie accelerating trends of datafication with a normative commitment to the principles of social justice-a commitment to the achievement of a society that is equitable, fair, and capable of confronting the root causes of injustice.However, despite the seeming novelty of such a data justice pedigree, this joining up of the critique of the power imbalances that have shaped the digital and "big data" revolutions with a commitment to social equity and constructive societal transformation has a deeper historical, and more geographically diverse, provenance. As the stories of the data justice initiatives, activism, and advocacy contained in this volume well evidence, practices of data justice across the globe have, in fact, largely preceded the elaboration and crystallisation of the idea of data justice in contemporary academic discourse. In telling these data justice stories, we hope to provide the reader with two interdependent tools of data justice thinking: First, we aim to provide the reader with the critical leverage needed to discern those distortions and malformations of data justice that manifest in subtle and explicit forms of power, domination, and coercion. Second, we aim to provide the reader with access to the historically effective forms of normativity and ethical insight that have been marshalled by data justice activists and advocates as tools of societal transformation-so that these forms of normativity and insight can be drawn on, in turn, as constructive resources to spur future transformative data justice practices.
