### Calculus for the Life Sciences: A Modeling Approach Volume 2

Exercise D.2.25. Wilson’s statement is a very interesting statement describing a relation between the number of species to be found on an island and the area of the island and has been confirmed in several locations. It does not, however, describe the competition or other interactions between species that might lead to the relationship and therefore does not meet our definition of a Mathematical Model. The relation has been derived from very elementary first principles by J. Harte, T. Zillio, E. Conlisk, and A. B. Smith, Maximum entropy and the state-variable approach to macroecology, Ecology 89 (2008), 2700-2711, that applies when the number of individuals per species is small.

### A Qualitative Study of the Ways Students from the Biological and Life Sciences Solve Calculus Accumulation Tasks.

accumulation (approximately 50 minutes). For the purposes of this study, the results from the first phase are only used to describe the students’ backgrounds and so analysis of that aspect of that data is not presented. In each of the five calculus tasks, the students are presented with a rate of change function of some quantity and questions about the accumulation of said quantity over various periods of time. Task 1 has been omitted from analysis in the current study as students did not tend to be as descriptive in their thinking during work on this task. Analyzing this data is among the plans for future research. See Table 1 for a summary of each tasks under analysis in the current study. To answer the research question: “What role does context play in how undergraduate students majoring in the biological and life sciences solve calculus tasks involving accumulation?”, the contexts for the tasks were chosen to be diverse but relevant for the students’ backgrounds. Furthermore, to more directly investigate this potential impact of context on students’ solution strategies, two tasks were included that were similar in terms of the underlying mathematical concepts, but were presented in

Charles Darwin, Origin of Species. Chap. VI, Difficulties of the Theory. “We see the same fact in ascending mountains, and sometimes it is quite remarkable how abruptly, as Alph. de Candolle has observed, a common alpine species disappears. The same fact has been noticed by E. Forbes in sounding the depths of the sea with the dredge. To those who look at climate and the physical conditions of life as the all-important elements of distribution, these facts ought to cause surprise, as climate and height or depth graduate away insensibly [our emphasis].”

### Cellular Automation: A discrete approach for modeling and simulation of Artificial Life Systems

Cellular Automation & ALife thus are advanced innovative and interesting field of computer science. The above detailed description of activities is sufficient to show that the activities pursued under this label are aimed at replicating some of the very basic activities of living beings. The basic issues of Artificial Life and Artificial Intelligence pertain to the issues investigated. Whereas AI has traditionally concentrated on the complex functions of human beings, such as chess playing, text comprehension, medical diagnosis, and so on. ALife mainly concentrates on basic natural behaviours, emphasizing survivality in complex environments. According to Brook‟s, an examination of the evolution of life on earth reveals the most of the time was spent developing the basic intelligence. The elemental faculties evolved to enable mobility in a dynamic environment and sensing of the surroundings to a degree sufficient to achieve the necessary maintenance of life and reproduction.

### On the Scope Interaction of Japanese Indefinites: An Epsilon Calculus Approach

Abstract. This study explores the scope properties of some indefinites in Japanese in terms of epsilon calculus. Different from ordinary noun phrases, quantificational noun phrases like indefinites are assigned higher-order categories and/or types in syntax, and taken to denote functions from sets to truth values in semantics, which results in great difficulty in deriv- ing proper interpretations of sentences with quantified expressions, given the tight syntax- semantics relation built into theories of grammar. We simply deal with all quantified expres- sions as terms of type e, and treat indefinites as choice functions, i.e., functions that apply to sets and arbitrarily select one of their members. Some indefinites can take arbitrarily wide scopes, depending on contextual information, whereas others have limitations on the freedom of scope taking. We adopt Dynamic Syntax to implement this idea, making it possible for the scope of indefinites to be left unspecified and fixed in a later stage of parsing.

### Some Integral Inequalities Using Quantum Calculus Approach

Abstract. The aim of this paper is to introduce a new class of preinvex functions which is called as generalized beta preinvex functions. We show that this class includes some other new classes of preinvex functions. We derive some new integral inequalities using the approach of quantum calculus. These integral inequalities involve generalized preinvex functions and q-Euler-Beta functions. Our results can be viewed as new quantum estimates for trapezoidal like inequalities. Some new special cases are also discussed which can be deduced from the main results of the paper.

There are different modes of packaging. Generally, container-packing is considered ideal for packing fruits or vegetables because these are easy to handle, provide good protection from mechanical damage, have adequate ventilation and convenient for merchandising. They could easily carry printed information about the product packed and are helpful in advertising about the product. Fancy containers such as fiberboard boxes, or wooden or plastic crates, are often used for high-value products. Inexpensive containers such as bamboo baskets or nylon net sacs are commonly used for low-priced products. The results are shown in Table 2. It is indicated that majority of the respondent in sampled area growers used bamboo baskets for packing and transporting their produce to the market whether supplied in a local or wholesale market.

### Applications of hydrogen isotopes in the life sciences

The unique MS-pattern obtained from natural and labeled isotopologues drastically simplifies analysis and provides a wealth of inspiring information and previously unprecedented levels of insight from a wide and continuously growing range of applications in many disciplines within the life sciences and beyond. The ability to measure naturally abundant isotope ratios has paved the way for a number of scientific breakthroughs in forensic sciences, geochemistry, ecology, and physiology. Additionally, analytical approaches incorporating stable isotopes have delivered now indispensable tools for relative and absolute quantification, for delineation of cellular metabolism, and for investigation of responses to various stimuli. Having stated this, perhaps most importantly, the employment of such methods provides a dynamic view on biosynthethic pathways, protein turnover, and systems-wide metabolic networks. Indeed, further expansion of isotope labeling to the whole-systems level, together with recent advances in bioinformatics, will bring us closer to a true systems biology understanding.

### Polarization modeling and predictions for DKIST part 2: application of the Berreman calculus to spectral polarization fringes of beamsplitters and crystal retarders

Figure 17. The Mueller matrix of WFS-BS1 sampled at δλ / λ of 1,000,000 using the Berreman calculus. The [0,0] Mueller matrix element has been used to normalize all subsequent elements to separate transmission effects from polarization as in Equation 2. The [1,1] element QQ/II is identically 1 in this plot. There are transmission, diattenuation (polarizance) and retardance fringes in this BS. The blue curve shows the uncoated 43mm thick Infrasil beamsplitter with roughly 3.5% reflection on both entrance and exit surfaces. The black curve shows the Berreman model with an uncoated front surface and an 18-layer broad-band anti-reflection coating from Infinite Optics applied to the back surface. The nominal wavelength is 400nm with a fringe period of roughly 1.3pm. The anti-reflection coating reduces the amplitude of all fringes: transmittance, diattenuation (polarizance) and retardance. The U V and V U terms show a net change in retardance as expected for adding a coating on a tilted optic though retardance fringe amplitude is slightly reduced.

### The reality of implementation of competencies approach in teaching Sciences of Life and Earth in Moroccan public school

A BSTRACT : The research study of the implementation of the philosophy of the competency approach which was carried out in all school curricula; especially the curriculum related to life and earth science, at different levels in the public middle and high schools in Morocco. This has shown significant findings after studying and analyzing the data questionnaire that has been handed out to both public middle and high school teachers in the country. We came to the following findings:

### EuroBioForum III – Connecting Life Sciences

The aim of the proposed project is the combination of both mechanisms in one novel natural system, which is able to generate H 2 directly from water using solar energy. Up to now, an organism which couples these two principal processes with an efficiency high enough for competitive hydrogen production does not exist. Europe has world-wide the leading expertise in the field of bio- hydrogen-related research – moreover, the EU hosts the highest density of groups working in the biohydrogen sector. By integration of the already established national and European-wide networks of biologists, biochemists, biophysicists and engineers we are aiming to systemati- cally investigate and improve the natural key components of this process (especially the water splitting photosys- tem, the hydrogenase and the associated metabolism) by directed and random approaches. In a second step, the designed components will be assembled within a cyanobacterial host, which finally produces H 2 in a light dependent manner under a broad range of environmen- tal conditions. By exploiting the unusual potential and removing the energetic barriers of the cyanobacterial metabolism, the designed organism has the potential for up to 100-fold higher hydrogen production rate than the most efficient photosynthetic H 2 producer known so far. The advantages are three-fold: (i) CO 2 is being used up for producing biomass, (ii) oxygen evolves, and (iii) the biological system allows self-reproduction and self-repair at extremely low costs – which may be an important step towards renewable and CO 2 neutral energy generation. Furthermore, in parallel, simple and cost-effective pho- tobioreactors will be developed for this new organism,

### OBML – Ontologies in Biomedicine and Life Sciences

In the area of knowledge representation and applied ontology, the OBML workshop benefited from discussions of how to represent dispositions [1] and grains, components and mixtures [2] in biomedical ontologies. These topics are important for representing diseases, chemical entities and physiological processes that involve solutions such as blood. Dispositions are widely discussed both in philosophy [3-6], in the formal ontol- ogy community [7-10] as well as in the context of medical applications and represent- ing disease [11,12]. A major challenge in representing dispositions is their context dependence, their dependence on a trigger, as well as the relation between dispositions and the processes that may be their realizations. Another problem arises due to the absence of relations with more than two arguments in description logics underlying the Web Ontology Language (OWL) [13,14]. The article “Representing dispositions” investigates how to represent dispositions in OWL, including their triggers and con- texts, discusses applications in disease ontologies and ontologies of chemistry and pro- vides an outlook on complex dispositions that can be realized through multiple kinds of processes or use multiple triggers. The paper “ Grains, Components and Mixtures in Biomedical Ontologies ” discusses competing representations of collectives (multiple entities of the same sort) for an adequate representation of substance mixtures. The authors argue that a strict dichotomy between (homogeneous) collectives and (hetero- geneous) compounds, as advocated in previous work, is problematic. For instance, the distinction between isomeric subtypes of a molecule can be important in one use case but might be neglected in another one. Two different ways of representing mixtures are presented: (i) mixtures are the additions of two or more fractions of collectives, or (ii), mixtures are collectives of two or more types of granular parts. Using OWL-DL and the upper-level ontology BioTop [15], the authors demonstrate how the equiva- lence between both representations can be computed.

### INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES

The quality of water is deteriorating due to inorganic anions and cations being released from domestic and industrial effluent. By the year 2030, when Kenya will be have attained an industrial economy, domestic and Industrial water will be a scarce resource. Most of the groundwater will be highly polluted and some of the water bodies will be covered by vegetation as a result of eutrophication and render the water non-potable. According to a report by Kenya Bureau of Standards, the territorial area of Kenya is 582,646 km 2 with 11,230 km 2 (1.927%) under surface water while the rest 571,416 km 2 (98.073%) on land. 85% of the land area is classified as Arid and Semi-Arid Land (ASAL) therefore making the only remaining 15% sustain more than 75% of the population. The average annual water available is 20.2 billion m 3 which corresponds to 647 m 3 per person per year. This classifies Kenya as a water scarce country since it falls way below the 1,000 m 3 per person per year threshold.

### LEVERAGING BIG DATA IN LIFE SCIENCES

For life sciences sales reps, comprehensive data mining, analysis and visualization can optimize approaches to physicians. Solutions that focus on the analysis of data for the purpose of extracting insights and knowledge streamline such decision-making processes. By bringing together prescription drug data, call planning and CRM data on iPads, your field force will be better prepared to more effectively target and engage the prescribing physician. Such analytic tools also help sales representatives with performance-over-time in therapeutic market prescriptions while identifying valuable new prospects.

### Oracle Life Sciences Data Hub

Figure 3–2 shows the process of creating a new Program definition and instance. The process is similar for all object types. You first create the object as a whole, classify both the definition and the instance, then define component objects: in the case of Programs these include Table Descriptors, Source Code, Parameters, and Planned Outputs. All executable instances require mapping Table Descriptors to Table instances and defining at least one Execution Setup. You must install all object instances in their Work Area, assign user groups for object security and validate the definition and the instance according to your company's policies.

### EuroBioForum II – Connecting Life Sciences

The EuroBioForum is an annual forum where research- ers, funding organisations and other stakeholders thoughout Europe meet to discuss future life sciences priorities. Identification of these life sciences topics is based on ideas put forward by the life sciences com- munity and by public and private funding organisations across Europe via a Call for Expressions of Interest. Following a selection by an international Steering Committee, the programme for each workshop is then defined in close collaboration with the proposers of the selected topic. The objectives of the workshop could be any or a combination of the following: i) to outline the plan for a new research programme, ii) to define a com- mon strategic research agenda, or iii) to update current funders and sponsors and inform potential new ones.
