Algebraic Independence over Positive Characteristic: New Criterion and Applications to Locally Low Algebraic Rank Circuits
No full textThe motivation for this work comes from two problems--test algebraic independence of arithmetic circuits over a field of small characteristic, and generalize the structural property of algebraic dependence used by (Kumar, Saraf CCC'16) to arbitrary fields.
It is known that in the case of zero, or large characteristic, using a classical criterion based on the Jacobian, we get a randomized poly-time algorithm to test algebraic independence. Over small characteristic, the Jacobian criterion fails and there is no subexponential time algorithm known. This problem could well be conjectured to be in RP, but the current best algorithm puts it in NP^#P (Mittmann, Saxena, Scheiblechner Trans.AMS'14). Currently, even the case of two bivariate circuits over F_2 is open. We come up with a natural generalization of Jacobian criterion, that works over all characteristic. The new criterion is efficient if the underlying inseparable degree is promised to be a constant. This is a modest step towards the open question of fast independence testing, over finite fields, posed in (Dvir, Gabizon, Wigderson FOCS'07).
In a set of linearly dependent polynomials, any polynomial can be written as a linear combination of the polynomials forming a basis. The analogous property for algebraic dependence is false, but a property approximately in that spirit is named as ``functional dependence'' in (Kumar, Saraf CCC'16) and proved for zero or large characteristic. We show that functional dependence holds for arbitrary fields, thereby answering the open questions in (Kumar, Saraf CCC'16). Following them we use the functional dependence lemma to prove the first exponential lower bound for locally low algebraic rank circuits for arbitrary fields (a model that strongly generalizes homogeneous depth-4 circuits). We also recover their quasipoly-time hitting-set for such models, for fields of characteristic smaller than the ones known before.
Our results show that approximate functional dependence is indeed a more fundamental concept than the Jacobian as it is field independent. We achieve the former by first picking a ``good'' transcendence basis, then translating the circuits by new variables, and finally approximating them by truncating higher degree monomials. We give a tight analysis of the ``degree'' of approximation needed in the criterion. To get the locally low algebraic rank circuit applications we follow the known shifted partial derivative based methods
Culturally-Competent Human-Robot Verbal Interaction
No full textThe article describes a system for culture-aware human-robot verbal interaction, that constitutes the basis for designing culturally-competent robots for health-care, i.e., robots able to autonomously re–configure their way of acting and speaking, when offering a service, to match the culture, customs, and etiquette of the person they are asstisting. The article shows how culture-aware verbal interaction is tightly related to cultural knowledge representation and acquisition, by describing the methodological and technological solutions adopted, and showing in details one of the preliminary experiments performed to design a culturally-competent robot
Report of Another Mutation Proven Case of Carbonic Anhydrase II Deficiency
No full textCarbonic anhydrase (CA) II deficiency results in an uncommon type of autosomal recessive sclerosing bone dysplasia with renal tubular acidosis and intracerebral calcification. We report a classic case of CA II-associated osteopetrosis with a previously reported homozygous frameshift mutation. Child was evaluated for short stature and failure to thrive. He was diagnosed as osteopetrosis in view of the presence of hepatosplenomegaly and increased bone density though hematological parameters were normal. Further evaluation showed presence of associated distal renal tubular acidosis raising a possibility of CA II deficiency. Mutation analysis revealed a previously reported homozygous frameshift mutation c.143-146delCTGT (p.Ser48Phefs 9) in CA2. Child has normal growth after initiation of alkali therapy
Beneficial Effects of Dietary Polyphenols on Gut Microbiota and Strategies to Improve Delivery Efficiency
No full textThe human intestine contains an intricate ecological community of dwelling bacteria, referred to as gut microbiota (GM), which plays a pivotal role in host homeostasis. Multiple factors could interfere with this delicate balance, including genetics, age, antibiotics, as well as environmental factors, particularly diet, thus causing a disruption of microbiota equilibrium (dysbiosis). Growing evidence support the involvement of GM dysbiosis in gastrointestinal (GI) and extra-intestinal cardiometabolic diseases, namely obesity, and diabetes. This review firstly overviews the role of GM in health and disease, then critically reviews the evidence regarding the influence of dietary polyphenols in GM based on preclinical and clinical data, ending with strategies under development to improve the efficiency of delivery. Although the precise mechanisms deserve further clarification, preclinical and clinical data suggest that dietary polyphenols present prebiotic properties and exert antimicrobial activities against pathogenic GM, having benefits in distinct disorders. Specifically, dietary polyphenols have been shown the ability to modulate GM composition and function, interfering with bacterial quorum sensing, membrane permeability, as well as sensitizing bacteria to xenobiotics. In addition, can impact gut metabolism and immunity and exert anti-inflammatory properties. In order to overcome the low bioavailability, several different approaches have been developed, aiming to improve the solubility and transport of dietary polyphenols throughout the GI tract and deliver in the targeted intestinal regions. Although more research is still needed, particularly translational and clinical studies, the biotechnological progress achieved during the last years opens up good perspectives to, in a near future, be able to improve the use of dietary polyphenols modulating GM in a broad range of disorders characterized by a dysbiotic phenotype
Algebraic Independence over Positive Characteristic: {N}ew Criterion and Applications to Locally Low Algebraic Rank Circuits

The CARESSES EU-Japan project: making assistive robots culturally competent
No full textThe nursing literature shows that cultural competence is an important requirement for effective healthcare. We claim that personal assistive robots should likewise be culturally competent, that is, they should be aware of general cultural characteristics and of the different forms they take in different individuals, and take these into account while perceiving, reasoning, and acting. The CARESSES project is an Europe-Japan collaborative effort that aims at designing, developing and evaluating culturally competent assistive robots. These robots will be able to adapt the way they behave, speak and interact to the cultural identity of the person they assist. This paper describes the approach taken in the CARESSES project, its initial steps, and its future plans
Financial inclusion, Its determinants and impact on economic growth: an empirical study of India with Reference to BRICS economies
No full textDesire for a financially inclusive economy has been the foremost priority; however, the
road to achieve financial inclusion is not so easy. This research is an attempt to identify
the determinants of financial inclusion. Indian economy has been treading on the path of
financial inclusiveness. This study tries to analyse financial inclusion by collecting data
through a questionnaire to examine the status and relation of determinants of financial
inclusion with Economic growth. In the later part an effort is made to examine financial
inclusion in BRICs economies, using secondary data. This will help in presenting a true
and holistic picture of financial inclusion in India in relation to other BRICS economies
and also help to create a model associating determinants of financial inclusion with
economic growth. The first step to increase financial inclusion is to increase the access to financial services.
Hence, the first determinant of financial inclusion considered in this study is access to
financial services. A five-point Likert scale has been employed for assessing the relation
among determinants of financial inclusion and economic growth. Usage, Digitalisation
and FinTech are included as important dimensions of access to financial services. Any
effort towards financial inclusion will be incomplete without considering financial
initiatives. Hence, another important determinant of financial inclusion considered is
financial initiatives. Financial initiatives cover two important dimensions, viz. financial
Policy and financial schemes. The third important determinant of financial inclusion
considered in the study is financial literacy. Financial literacy covers two dimensions,
Financial Inclusion Awareness and Financial Inclusion competency. Financial Inclusion
awareness focuses on primary knowledge and deeper understanding and knowledge is
covered through competency. The study examines the relation among determinants of
financial inclusion and economic growth. The research also examines the mediation of
financial literacy among Access to financial services and economic growth. For financial
initiatives a direct relation is observed with economic growth. Moreover, adequate research has not been done for examining relation among
determinants of financial inclusion in BRICS economies. Initially for comparing
financial inclusion of India with Brazil, Russia, China and South African’ economies, the
variables included are: i) the number of depositors and ii) ATM/user iii) Broad Money;iv) Bank Branches; v) Domestic Credit to Private Sector; vi) Internet Users; vii)
Inflation; viii) Exchange Rate. Results depict that cross section random model is good fit
when using GDP as the dependent variable and also in case of GDP/Capita too. The
results support that determinants of financial inclusion assist in enhancing economic
growth. The study thus, presents a holistic view of financial inclusion status in India and
financial inclusion in BRICS economies. The results will help focus on certain
determinants like institutional credit, increasing depositors and increasing awareness
through certain macro-indicators like inflation rate and exchange rate. These results are
important for policy makers and practitioners
