description: The role of centrosomes/centrioles during mitotic spindle assembly in vertebrates remains controversial. In cell-free extracts and experimentally derived acentrosomal cells, randomly oriented microtubules (MTs) self-organize around mitotic chromosomes and assemble anastral spindles [1, 2, 3]. However, vertebrate somatic cells normally assemble a connected pair of polarized, astral MT arrays – termed an amphiaster (“a star on both sides” [4]) – that is formed by the splitting and separation of the microtubule-organizing center (MTOC) well before nuclear envelope breakdown (NEB) [5]. Whether amphiaster formation requires splitting of duplicated centrosomes is not known. We found that when centrosomes were removed from living vertebrate cells early in their cell cycle, an acentriolar MTOC re-assembled, and prior to NEB, a functional amphiastral spindle formed. Cytoplasmic dynein, dynactin, and pericentrin are all recruited to the interphase aMTOC, and the activity of kinesin-5 is needed for amphiaster formation. Mitosis proceeded on time and these karyoplasts divided in two. However, ~35% of aMTOCs failed to split/separate before NEB, and these entered mitosis with persistent monastral spindles. The chromatin-mediated RAN-GTP pathway could not restore bipolarity to monastral spindles, and these cells exited mitosis as single daughters. Our data reveal the novel finding that MTOC separation and amphiaster formation does not absolutely require the centrosome, but in its absence, the fidelity of bipolar spindle assembly is highly compromised.

description: A dicembre 2020, il Gruppo Storie dell’Istituto Nazionale di Astrofisica (INAF) ha pubblicato insieme al magazine di Didattica e Divulgazione dell’Ente, EduINAF, il Portfolio degli spettacoli dell’INAF. Il Portfolio è il risultato di un’accurata ricognizione in collaborazione con i referenti degli stessi ed è unico nel suo genere per un Ente di ricerca. Comprende una trentina di spettacoli, a tema astrofisico o scientifico, prodotti negli anni dal personale INAF in autonomia o in collabora-zione con realtà professionali. Nel Portfolio, ogni spettacolo è descritto in una scheda informativa e la fruizione è resa immediata grazie a filtri appositi. Il Portfolio è man mano aggiornato per meglio rispondere alle esigenze e curiosità del pubblico in cerca di approcci non tradizionali nell’esplorazione dell’astronomia e della ricerca in generale. Ad accompagnare il Portfolio, un breve video per la disseminazione sui canali social e un segnalibro dedicato, in preparazione, da offrire in incontri con scuole e in eventi con il pubblico. Grazie alla visione d’insieme offerta dal Portfolio, nell’Ente sono nate valutazioni per massimizzare la visibilità degli spettacoli tramite l’organizzazione di un ‘Festival INAF diffuso’. In questo report descriviamo il Portfolio, il suo contesto, le criticità riscontrate e i progetti futuri.

description: We study the homotopy type of the space of metrics of positive scalar curvature on high-dimensional compact spin manifolds. Hitchin used the fact that there are no harmonic spinors on a manifold with positive scalar curvature to construct a secondary index map from the space of positive scalar metrics to a suitable space from the real $K$-theory spectrum. Our main results concern the nontriviality of this map. We prove that for $2n \geq 6$, the natural $KO$-orientation from the infinite loop space of the Madsen--Tillmann--Weiss spectrum factors (up to homotopy) through the space of metrics of positive scalar curvature on any $2n$-dimensional spin manifold. For manifolds of odd dimension $2n+1 \geq 7$, we prove the existence of a similar factorisation. When combined with computational methods from homotopy theory, these results have strong implications. For example, the secondary index map is surjective on all rational homotopy groups. We also present more refined calculations concerning integral homotopy groups. To prove our results we use three major sets of technical tools and results. The first set of tools comes from Riemannian geometry: we use a parameterised version of the Gromov--Lawson surgery technique which allows us to apply homotopy-theoretic techniques to spaces of metrics of positive scalar curvature. Secondly, we relate Hitchin's secondary index to several other index-theoretical results, such as the Atiyah--Singer family index theorem, the additivity theorem for indices on noncompact manifolds and the spectral-flow index theorem. Finally, we use the results and tools developed recently in the study of moduli spaces of manifolds and cobordism categories. The key new ingredient we use in this paper is the high-dimensional analogue of the Madsen--Weiss theorem, proven by Galatius and the third named author.

description:

This article deals with two essential features pertaining to the development of free ports and free zones: the freedom of movement of goods and customs-related operations. Freedom of transit is one of the fundamental international trade principles which was incorporated in the General Agreement on Tariffs and Trade (GATT) immediately after World War II. Regarding the European Union context, the EU internal market is based on the freedom of movement of goods. In line with Article 26 of the Treaty on the Functioning of the European Union (TFEU), the internal market «shall comprise an area without internal frontiers in which the free movement of goods, persons, services and capital is ensured in accordance with the provisions of the Treaties». For the importance of examining EU customs legislation, to better understand the role of free ports and free zones, especially in terms of fiscal and customs benefits (e.g. duties are partially reduced or temporary suspended), attention is focused on: Union Customs Code in force (Regulation 952/2013); the concept of customs valuation; some critical issues arising when non-EU goods are imported into the EU, considering both the phase of release for free circulation and that of release for consumption.

description: We report a general method to examine the recognition of post-translational modifications (PTMs) by antibodies and proteins. We use this method to evaluate the binding of modification-specific antibodies and chromatin-associating factors to an array of high-purified, biotinylated peptides (derived from human histone sequences) harboring multiple PTMs printed onto streptavidin-coated glass slides. We find that modification-specific antibodies are both more promiscuous in their PTM recognition than expected and highly influenced by neighboring PTMs. Binding of chromatin-associating factors is also influenced by combinatorial PTMs, giving further support for the “Histone Code” hypothesis. Thus we report the first thorough characterization of PTM influence on antibody recognition and describe a tool for the rapid and inexpensive assessment of chromatin-associating factor binding specificity.

description: Tension sensing of bi-oriented chromosomes is essential for the fidelity of chromosome segregation. The spindle assembly checkpoint (SAC) conveys lack of tension or attachment to the anaphase promoting complex. Components of the SAC (Bub1) phosphorylate histone H2A (S121) and recruit the protector of cohesin, Shugoshin (Sgo1) to the inner centromere. How the chromatin structural modifications of the inner centromere are integrated into the tension sensing mechanisms and the checkpoint are not known.

description: The combined considerations of both the bulk liquid-drop-type behavior and the quantized aligned rotation with cranked Skyrme-Hartree-Fock approach revealed previously [Phys. Lett. B 738 (2014) 401] that even-even, N=Z, toroidal high-spin isomeric states have general occurrences for light nuclei with A between 28 and 52. We find that in this mass region there are in addition N not equal to Z toroidal high-spin isomers when the single-particle shells for neutrons and protons occur at the same cranked frequency $\hbar ω$. Examples of N not equal to Z toroidal high-spin isomers, $^{36}_{16}$S$_{20}$($I$=74$\hbar$) and $^{40}_{18}$Ar$_{22}$($I$=80,102$\hbar$), are located and examined. The systematic properties of these N not equal to Z toroidal high-spin isomers fall into the same regular (muti-particle)-(muti-hole) patterns as other N=Z toroidal high-spin isomers.

description: The aim of this article is to undertake a reflection on the caricatural character of Quevedo’s culta latiniparla and her inclusion in No hay burlas con el amor, urban comedy by Calderón de la Barca. The article will adopt a transnational and intertextual approach linked to the reception outside Iberian borders of educated woman who boast a pompous language. In particular, following a series of critical controversies on the possibility that Molière could have been inspired by this play for his work Les femmes savantes, a contrastive analysis will be carried out to assess the real entity of the Calderonian reverberations in Molière’s text, showing both points of contact and discrepancies related to reworking the wise and hembrilatina lady cliché.

description: The striking morphology of the Golgi complex has fascinated cell biologists since its discovery over 100 years ago. Yet, despite intense efforts to understand how membrane flow relates to Golgi form and function, this organelle continues to baffle cell biologists and biochemists alike. Fundamental questions regarding Golgi function, while hotly debated, remain unresolved. While Golgi function is historically described from a protein-centric point of view, we now appreciate that conceptual frameworks for how lipid metabolism is integrated with Golgi biogenesis and function are essential for a mechanistic understanding of this fascinating organelle. It is from a lipid-centric perspective that we discuss the larger question of Golgi dynamics and membrane trafficking. We review the growing body of evidence for how lipid metabolism is integrally written into the engineering of the Golgi system, and highlight questions for future study.

description: Aims First, to conduct a detailed exploration of the prospective relations between four commonly used anthropometric measures with incident diabetes and to examine their consistency across different population subgroups. Second, to compare the ability of each of the measures to predict five-year risk of diabetes. Methods We conducted a meta-analysis of individual participant data on body mass index (BMI), waist circumference (WC), waist-hip and waist-height ratio (WHtR) from the Obesity, Diabetes and Cardiovascular Disease Collaboration. Cox proportional hazard models were used to estimate the association between a one standard deviation increment in each anthropometric measure and incident diabetes. Harrell's concordance statistic was used to test the predictive accuracy of each measure for diabetes risk at five years. Results Twenty-one studies with 154,998 participants and 9342 cases of incident diabetes were available. Each of the measures had a positive association with incident diabetes. A one standard deviation increment in each of the measures was associated with 64–80% higher diabetes risk. WC and WHtR more strongly associated with risk than BMI (ratio of hazard ratios: 0.95 [0.92,0.99] – 0.97 [0.95,0.98]) but there was no appreciable difference between the four measures in the predictive accuracy for diabetes at five years. Conclusions Despite suggestions that abdominal measures of obesity have stronger associations with incident diabetes and better predictive accuracy than BMI, we found no overall advantage in any one measure at discriminating the risk of developing diabetes. Any of these measures would suffice to assist in primary diabetes prevention efforts.
Ante-Litteram One Health in India

description:

Historical research on One Health is offering interesting information about the development of this concept within human and animal health institutions and professions. In contrast, little is known about whether and how local communities have discussed – in their own terms – and managed One Health issues. This paper presents three examples of community-led debate and action on One Health in India: the eco-religion of Bishnois, the collapse of the vulture population, and plastic pollution in cows’ bodies. More research from the social sciences and the humanities is necessary to understand and learn from the dynamics of multispecies entanglements at the local level.

description: In the third part of this series of papers, we establish several topological results that will become important for studying the long-time behavior of Ricci flows with surgery. In the first part of this paper we recall some elementary observations in the topology of 3-manifolds. The main part is devoted to the construction of certain simplicial complexes in a given 3-manifold that exhibit useful intersection properties with embedded, incompressible solid tori. This paper is purely topological in nature and Ricci flows will not be used.

description: Mechanical forces regulate cell behavior and function during development, differentiation, and tissue morphogenesis. In the vascular system, forces produced by blood flow are critical determinants not only of morphogenesis and function, but also pathological states such as atherosclerosis. Endothelial cells (ECs) have numerous mechanotransducers, including platelet endothelial cell adhesion molecule-1 (PECAM-1) at cell-cell junctions and integrins at cell-matrix adhesions. However, the processes by which forces are transduced to biochemical signals and subsequently translated into downstream effects are poorly understood.

description: Ordinary differential equation models are used to describe dynamic processes across biology. To perform likelihood-based parameter inference on these models, it is necessary to specify a statistical process representing the contribution of factors not explicitly included in the mathematical model. For this, independent Gaussian noise is commonly chosen, with its use so widespread that researchers typically provide no explicit justification for this choice. This noise model assumes ‘random’ latent factors affect the system in the ephemeral fashion resulting in unsystematic deviation of observables from their modelled counterparts. However, like the deterministically modelled parts of a system, these latent factors can have persistent effects on observables. Here, we use experimental data from dynamical systems drawn from cardiac physiology and electrochemistry to demonstrate that highly persistent differences between observations and modelled quantities can occur. Considering the case when persistent noise arises owing only to measurement imperfections, we use the Fisher information matrix to quantify how uncertainty in parameter estimates is artificially reduced when erroneously assuming independent noise. We present a workflow to diagnose persistent noise from model fits and describe how to remodel accounting for correlated errors.
The Efficacy of True Speech

description:

According to a widespread interpretation, in Gorgias’ philosophy of language there is no room for truth at all. The only aim of logos for him would be effective persuasion and speech would be constrained by nothing but persuasiveness itself. Referring to Encomium of Helen, I try to point out, however, that in Gorgias there is an attempt to investigate the complex relationship between truth and efficacy in the functioning of language. I also suggest that, seen from this perspective, Gorgias’ conception of truth shows significant points of contact with Rorty’s and, above all, Foucault’s thinking.

Revision of the taxonomy, systematics and biogeography of Natatolana (Crustacea: Isopoda: Cirolanidae)

Year: 2023
Subjects: classificationCode: 399999
subject: Other education not elsewhere classified

description: Taxonomic and biogeographical information is reviewed for all species of Natatolana. A revised diagnosis of the genus and a key to species is presented. Fifteen new species from Australia and New Zealand are described. Redescriptions and/or new illustrations are provided for thirteen poorly known species and lectotypes are designated for three species. One subspecies is identified as a species and four species are placed in synonymy. Four species in three genera related to Natatolana are also described. The reliability of morphological characters in separating species of Natatolana is supported by a case study utilising allozyme electrophoresis. The systematics of Natatolana is revised using cladistic techniques to analyze phylogenetic relationships among species in the genus and among genera of the Cirolanidae. This indicates that the classification of Natatolana and Dolicholana in the subfamily Conilerinae is inappropriate. The setation pattern of pereopod 7 is recognised as a unambiguous synapomorphy of the species placed within Natatolana. This can be used, with several homoplastic synapomorphies, to define the genus as a monophyletic group. Several clades within Natatolana are also identified. However, the relationships within and among these clades are not well resolved. It is suggested that this is a consequence of evolutionary processes, such as stabilisation of selection pressures and hybridization, resulting in homoplasy and difficulties in defining morphological characters which can be used in phylogenetic analysis. Comparison of the distribution of species of Natatolana with hypothesised phylogenetic relationships indicates that the genus may have diversified prior to the early Cretaceous period, 144 million years before present, and become widespread as a result of continental drift. Studies, which examine functional morphology, utilise molecular techniques and obtain specimens from additional geographic areas, are recommended to further clarify species relationships and biogeographic patterns.

description: We consider the triple $(\mathcal{A},\mathcal{A}',\mathcal{A}^H)$ of hyperplane arrangements and the division of their characteristic polynomials. We show that the freeness of $\mathcal{A}^H$ and the division of $χ(\mathcal{A};t)$ by $χ(\mathcal{A}^H;t)$ confirm the freeness of $\mathcal{A}$. The key ingredient of this "division theorem" on freeness is the fact that, if $χ(\mathcal{A}^H;t)$ divides $χ(\mathcal{A};t)$, then the same holds for the localization at the codimension three flat in $H$. This implies the local-freeness of $\mathcal{A}$ in codimension three along $H$. Based on these results, several applications are obtained, which include a definition of "divisionally free arrangements". It is strictly larger than the set of inductively free arrangements. Also, in the set of divisionally free arrangements, the Terao's conjecture is true.

description:

Crowdfunding platforms have been particularly relevant in the ambit of innovations introduced with the development of Fintech, including those that base their activity on lending (the so called “lending-based crowdfunding” platforms). The active platforms - whose number in Italy is still relatively small - carry out a market activity that facilitates the matching of interests between those who are in surplus (and wish to use money towards a return), and those who are in deficit (and wish to obtain funding). This article aims to provide a look at lending crowdfunding, with a twofold purpose: (i) understanding how the relevant platforms can be legally qualified, also with regard to their compatibility with the activities reserved by law to financial intermediaries; ii) analyzing the possible scenarios related to the “European Crowdfunding Service Providers” EU Regulation (ECSP), considering that only in recent years the Commission has decided to go beyond a mere monitoring of the sector.

description: Internal physical structure can drastically modify the properties of waveguides: photonic crystal fibers are able to confine light inside a hollow air core by Bragg scattering from a periodic array of holes, while metamaterial loaded waveguides for microwaves can support propagation at frequencies well below cutoff. Anisotropic metamaterials assembled into cylindrically symmetric geometries constitute light-guiding structures that support new kinds of exotic modes. A microtube of anodized nanoporous alumina, with nanopores radially emanating from the inner wall to the outer surface, is a manifestation of such an anisotropic metamaterial optical fiber. The nanopores, when filled with a plasmonic metal such as silver or gold, greatly increase the electromagnetic anisotropy. The modal solutions in anisotropic circular waveguides can be uncommon Bessel functions with imaginary orders.

Dietary intake and habits of South Asian immigrants living in Western countries
Creators: name: Stevens, J.

Publisher: name: Oxford University Press
Year: 2017

description: Previous reviews have indicated that immigration from South Asian to Western countries leads to unhealthy changes in diet; however, these reviews have been limited by the methods used in some included studies. This critical narrative review summarizes findings from original research articles that performed appropriate statistical analyses on diet data obtained using culturally appropriate diet assessment measures. All studies quantitatively compared the diets of South Asian immigrants with those of residents of Western or South Asian countries or with those of South Asian immigrants who had varying periods of time since immigration. Most studies examined total energy and nutrient intake among adults. Total energy intake tended to decrease with increasing duration of residence and immigrant generation, and immigrants consumed less protein and monounsaturated fat compared with Westerners. However, findings for intakes of carbohydrate, total fat, saturated fat, polyunsaturated fat, and micronutrients were mixed. Studies that examine food group intake and include South Asians living in South Asia as a comparison population are needed.
A Processability Approach to Instructed Language Learning in Multilingual Contexts

Existing research indicates a qualitative difference between Second Language Learning and Third Language Acquisition, and certain psycholinguistic and developmental aspects of multilingual learners merit investigation. The present article examines stages in receptive learner acquisition of English as a Third Language at Italian medium primary schools in South Tyrol (Italy) employing a picture selection task and implicational scaling analysis. It highlights the role that processing approaches to acquisition proposing constraints on developmental readiness and cross-linguistic influence may play in the emergence of receptive competence in morphosyntactic structures.

description: The budding yeast kinetochore is ~68nm in length with a diameter slightly larger than a 25nm microtubule [1]. The kinetochores from the 16 chromosomes are organized in a stereotypic cluster encircling central spindle microtubules. Quantitative analysis of the inner kinetochore cluster (Cse4, COMA) reveals structural features not apparent in singly attached kinetochores. The cluster of Cse4 containing kinetochores is physically larger perpendicular to the spindle axis relative to the cluster of Ndc80 molecules [2]. If there were a single Cse4 (molecule or nucleosome) at the kinetochore attached to each microtubule plus-end, the cluster of Cse4 would appear geometrically identical to Ndc80. Thus, the structure of the inner kinetochore at the surface of the chromosomes remains unsolved.

description: Employing ab initio electronic calculations, we propose a new type of two-dimensional (2D) topological insulator (TI), monolayer (ML) low buckled (LB) mercury telluride (HgTe) and mercury selenide (HgSe), with tunable band gaps. Monolayer LB HgTe undergoes a transition to a topological nontrivial phase under the appropriate in-plane tensile strain (ε > 2.6%) due to the combination effects of strain and spin orbital coupling (SOC). Under the 2.6%< ε <4.2% tensile strain, the band inversion and topological nontrivial gap are induced by the SOC. For ε >4.2%, the band inversion is already realized by strain but the topological gap is induced by SOC. The band gap of monolayer LB HgTe TI phase can be tuned over a wide range from 0 eV to 0.20 eV as the tensile strain increases from 2.6% to 7.4%. Similarly, the topological phase transition of monolayer LB HgSe is induced by strain and SOC as the strain ε >3.1%. The topological band gap can be 0.05 eV as the strain increases to about 4.6%. The large band gap of 2D LB HgTe and HgSe monolayers make this type of material suitable for practical applications at room-temperature.

Obesity as a Disease: Why Ignore the Numbers?
Creators: name: Stevens, J.
Publisher: name: Blackwell Publishing Inc.
Year: 2017

description: TO THE EDITOR: In a recent Perspective, Dr. Arya Sharma and Dr. Denise Campbell-Scherer presented their opinion that obesity should be considered a disease only after the development of recognizable signs and symptoms of impaired health. Prior to the clear diagnosis of obesity-driven impairment of physical, mental, or social health, they advise medical professionals to take a “watch-and-wait approach.” This stance is in direct opposition to prevention science and is dangerous to the public’s health.

description: Forty years following Deng Xiaoping’s 1978 “Reform and Opening-up” policy, the Chinese Communist Party (CCP) has overturned longstanding assumptions that China’s integration with the liberal international order was a foregone conclusion. As the ruling Xi Jinping government continues to promote an alternative international system premised on its authoritarian governance model, liberal societies along China’s border—namely, Hong Kong and Taiwan—have emerged as points of fierce resistance to political, cultural and economic domination. While many accounts examining Hong Kong and Taiwan’s complex geopolitical relationship to mainland China, few primarily explore the culturally mediated ideals that underly the CCP’s authoritarian governance, or the mass movements resisting against them—notably the 2014 Sunflower Movement in Taiwan and 2019-2020 anti-extradition protests in Hong Kong. Drawing upon cultural texts from mainland China, Taiwan and Hong Kong, this dissertation aims to examine the moral foundations of the unresolved and ongoing political clashes between China and its contested border regions. I identify the ubiquity of scientism—mediated through early modern utopian literature—in early 20th century Chinese intellectual culture as providing a foundation for the rapid flourishing of Marxist political philosophy throughout China following the 1919 May Fourth movement. I then contrast developments on the mainland with those in Taiwan, demonstrating the role played by popular music, particularly rock and roll, in fomenting the island’s democratization and continued resistance against the CCP’s efforts to politically unify Taiwan with China. Finally, using Hong Kong cinema as a case study, I draw a link between the ambivalent attitude towards authority and ad hoc creativity of anti-government protestors in Hong Kong and the cinematic subculture that thrived in the latter decades of British colonial rule. Ultimately, this dissertation aspires to overturn Marxist-inspired critical frameworks that subordinate cultural texts to the economic “base,” and locate the origins of political resistance where it belongs, in the realm of culturally mediated ideas.

This paper aims to discuss the genealogical contents and structure of the opening verses of Aeschylus’ Eumenides. Considering genealogies as mythical digressions ideologically orientated, I will outline those elements that do not appear elsewhere in traditions concerning the foundation of the Delphic oracle. By analysing the connections between the poetic imagery and the audience’s ritual and mythological competence, I will demonstrate how Aeschylus enhances Athens’ positive cultural role in the establishment of a panhellenic sanctuary such as Delphi. Thus, these opening verses allow us to observe the mechanisms of identity construction through mythopoesis.

description: The cleavage stage mouse embryo is composed of superficially equivalent blastomeres that will generate both the embryonic inner cell mass (ICM) and the supportive trophectoderm (TE). However, it remains unsettled whether the contribution of each blastomere to these two lineages can be accounted for by chance. Addressing the question of blastomere cell fate may be of practical importance, as preimplantation genetic diagnosis (PGD) requires removal of blastomeres from the early human embryo. To determine if blastomere allocation to the two earliest lineages is random, we developed and utilized a recombination-mediated, non-invasive combinatorial fluorescent labeling method for embryonic lineage tracing.

description: Social relationships are associated with health across adulthood. While experiences involving friends occur in our everyday lives, we know little about the implications of friends on momentary health. Additionally, racial backgrounds may influence friendship opportunities due to structural racism, which in turn, may affect ongoing friendship patterns and health. This dissertation investigated unique effects of friends on momentary health among Black and White American adults. Study 1 examined how often Black and White adults encountered friends in real-life settings using ecological momentary assessment (EMA) technique. Moreover, I examined whether encounters with friends affect momentary mood differently for these distinct racial groups and for those who endorse more friends as important ties. Multilevel models revealed that Black adults encountered friends just as much as White adults. At times when individuals met with friends, they had increased positive mood than when they did not (within-person association), and this was only observed in White adults. Further, individuals who encountered more friends during the study period had higher positive mood than those who encountered fewer friends (between-person association), and this was observed in Black adults. Using ambulatory physiological assessments and EMA reports, Study 2 examined how encounters with friends affect individuals’ cardiovascular health as indicated by heart rate variability (HRV). Study 2 also considered the quality of encounters and explored the racial differences. Findings did not reveal a robust within-person association between encounters with friends and HRV in the overall sample. Yet, race-stratified models revealed that when Black adults met with friends, they had reduced HRV than when they did not (within-person association), but Black adults who encountered more friends during the study period had higher HRV than their same-race counterparts who encountered fewer friends (between-person association). Together, findings suggest White adults may reap immediate emotional benefits at times when they encounter friends. Black adults may not obtain immediate health benefits, but friends could still be linked to their emotional and cardiovascular health in the long run. This work contributes to the racial health disparity literature by providing a better understanding of how friends may prevent mental or cardiovascular conditions for different racial groups.

description: Oncogenic mutations in the small Ras GTPases KRas, HRas, or NRas render the encoded proteins constitutively GTP-bound and active, which promote cancer [1]. Ras proteins share ~85% amino acid identity [2], are activated by [3] and signal through [4] the same proteins, and can exhibit functional redundancy [5][6]. Nevertheless, manipulating expression or activation of each isoform yields different cellular responses [7–10] and tumorigenic phenotypes [11–13], even when different ras genes are expressed from the same locus [6]. We now report a novel regulatory mechanism hardwired into the very sequence of RAS genes that underlies how such similar proteins impact tumorigenesis differently. Specifically, despite their high sequence similarity, KRAS is poorly translated compared to HRAS due to enrichment in genomically underrepresented, or rare, codons. Converting rare to common codons increased KRas expression and tumorigenicity to mirror that of HRas. Furthermore, in a genome-wide survey similar gene pairs with opposing codon bias were identified that not only manifested dichotomous protein expression, but were also enriched in key signaling protein classes and pathways. Thus, synonymous nucleotide differences affecting codon usage account for differences between HRas and KRas expression and function, and may represent a broader regulation strategy in cell signaling.
Macrospin in external magnetic field: Entropy production and fluctuation theorems

description: We consider stochastic rotational dynamics of a macrospin at a constant temperature, in presence of an external magnetic field. Starting from the appropriate Langevin equation which contains multiplicative noise, we calculate entropy production (EP) along stochastic trajectories, and obtain fluctuation theorems. The system remains inherently out of equilibrium due to a spin torque supporting azimuthal current, leading to an excess EP apart from the EP due to heat dissipation. The anomaly may be removed using a redefinition of dissipated heat and stochastic work done. Using numerical simulations, we obtain distribution functions for entropy production along stochastic trajectories to find good agreement with the detailed fluctuation theorem.

Social Information Signaling by Neurons in Primate Striatum

description: Social decisions depend on reliable information about others. Consequently, social primates are motivated to acquire information about the identity, social status, and reproductive quality of others [1]. Neurophysiological [2] and neuroimaging [3 and 4] studies implicate the striatum in the motivational control of behavior. Neuroimaging studies specifically implicate the ventromedial striatum in signaling motivational aspects of social interaction [5]. Despite this evidence, precisely how striatal neurons encode social information remains unknown. Therefore, we probed the activity of single striatal neurons in monkeys choosing between visual social information at the potential expense of fluid reward. We show for the first time that a population of neurons located primarily in medial striatum selectively signals social information. Surprisingly, representation of social information was unrelated to simultaneously expressed social preferences. A largely nonoverlapping population of neurons that was not restricted to the medial striatum signaled information about fluid reward. Our findings demonstrate that information about social context and nutritive reward are maintained largely independently in striatum, even when both influence decisions to execute a single action.► Single neurons in striatum encode social information ► Typically, striatal neurons signal social or fluid information, but not both ► Topographically distinct information channels process social and fluid reward

description: We theoretically study the transmittance for normal incidence of linearly polarized light between two media separated by a strained graphene monolayer. We analytically characterize the degree of dichroism and the transparency of graphene as a function of an arbitrary uniform strain and the incident polarization. We discuss how measurements of dichroism and transparency for two different polarization directions can be used to determine the magnitude and direction of strain. Ours findings result in very useful tools to tune the graphene absorption by mechanical strain, as well as to design nano-devices to determine crack propagation in materials.
