Digital holographic microscopy provides the ability to observe throughout a volume that is large compared to its resolution without the need to actively refocus to capture the entire volume. This enables simultaneous observations of large numbers of small objects within such a volume. We have constructed a microscope that can observe a volume of 0.4 µm × 0.4 µm × 1.0 µm with submicrometer resolution (in xy) and 2 µm resolution (in z) for observation of microorganisms and minerals in liquid environments on Earth and on potential planetary missions. Because environmental samples are likely to contain mixtures of inorganics and microorganisms of comparable sizes near the resolution limit of the instrument, discrimination between living and non-living objects may be difficult. The active motion of motile organisms can be used to readily distinguish them from non-motile objects (live or inorganic), but additional methods are required to distinguish non-motile organisms and inorganic objects that are of comparable size but different composition and structure. We demonstrate the use of passive motion to make this discrimination by evaluating diffusion and buoyancy characteristics of cells, styrene beads, alumina particles, and gas-filled vesicles of micron scale in the field of view.

Ecological Catastrophe

    Kalidas’s plays are replete with descriptive details of flora and fauna and vivid pictures of naturedrawn from diverse sources and rich imagery. His works particularly “Ritusambharam’’, “Meghdutam’’ and ‘’Abhijnanashakuntalam’’ also show a symbiotic relationship between man and nature. Though there are many works on his plays and epicscritiquingnature,its grandeur and other related aspects. This paper attempts to critique the Ecocritical concept of Romantic sublime in “Abhijnanashakuntalam “. This paper examines the ecosystem presented in this play by Kalidas, which endorses the emotional experiences of the wonder of nature. It also critiques the text with reference to Lee Rozelle’s  concept of ‘ ecosublime’ which suggests that sublime encounter with nature inspires awe which further invites ecological catastrophe as well as environmental responsibility. This paper further discusses the profundity of thought, emotion and spirit represented by spectacular landscapes, characters and living and non-living objects in the forest. It further interrogates the ecocentric setting of the play which extends an egalitarian perspective with respect to all elements of nature and acknowledges the intrinsic value of all living beings. The paper concludes that ‘Abhjjnashakuntalam’ presents the ecocritical perspective of society, culture and gender,which highlight nature and evoke emotional experiences with awe and wonder in postmodern world faced with danger of environmental catastrophe.

Broad Understanding

Too broad understanding of the term stress, which Selye himself and his followers used in their popular science works, reduces its scientific value. Based on a brief analysis of examples of the ambiguity of the term stress, it is proposed to restore its research significance. For that, the concept of stress should be used more strictly and unequivocally and it would not be allowed to use a commonly broad understanding the term in scientific papers. In the frame of earlier Selyes stress definition, it suggests a more detailed structuring of the term based on levels of studying of living objects, including genetic.

This study identifies and describes the local wisdom carried out by the coastal communities, especially the people of North Seram, Maluku in preserving the island and marine environment as well as the customary institutions in determining and guarding local wisdom of coastal communities to manage marine resources. The marine resource is started to weaken along with the development of modern technology. This paper provides contemporary phenomena regarding the weakness of customary laws and traditional institutions that regulate marine resources, including social values in the form of rituals, representing the relationship between humans and their environment. The protection of marine resources around them will be an important discussion to see the role of government and society in preserving marine and coastal resources. This study used a qualitative approach to produce descriptive explanations from reports, book reviews, and documents that describe theories and information of both past and present. The result is that the local wisdom maintained as superior cultural practices that are beneficial to human survival, especially in maintaining the sustainability and balance between humans and living objects.

AbstractObjects are the fundamental building blocks of how we create a representation of the external world. One major distinction amongst objects is between those that are animate versus inanimate. Many objects are specified by more than a single sense, yet the nature by which multisensory objects are represented by the brain remains poorly understood. Using representational similarity analysis of human EEG signals, we show enhanced encoding of audiovisual objects when compared to their corresponding visual and auditory objects. Surprisingly, we discovered the often-found processing advantages for animate objects was not evident in a multisensory context due to greater neural enhancement of inanimate objects—the more weakly encoded objects under unisensory conditions. Further analysis showed that the selective enhancement of inanimate audiovisual objects corresponded with an increase in shared representations across brain areas, suggesting that neural enhancement was mediated by multisensory integration. Moreover, a distance-to-bound analysis provided critical links between neural findings and behavior. Improvements in neural decoding at the individual exemplar level for audiovisual inanimate objects predicted reaction time differences between multisensory and unisensory presentations during a go/no-go animate categorization task. Interestingly, links between neural activity and behavioral measures were most prominent 100 to 200ms and 350 to 500ms after stimulus presentation, corresponding to time periods associated with sensory evidence accumulation and decision-making, respectively. Collectively, these findings provide key insights into a fundamental process the brain uses to maximize information it captures across sensory systems to perform object recognition.Significance StatementOur world is filled with an ever-changing milieu of sensory information that we are able to seamlessly transform into meaningful perceptual experience. We accomplish this feat by combining different features from our senses to construct objects. However, despite the fact that our senses do not work in isolation but rather in concert with each other, little is known about how the brain combines the senses together to form object representations. Here, we used EEG and machine learning to study how the brain processes auditory, visual, and audiovisual objects. Surprisingly, we found that non-living objects, the objects which were more difficult to process with one sense alone, benefited the most from engaging multiple senses.

This paper makes an attempt to explore the echoes of the vision of Hindu philosophy in the selected works of T. S. Eliot. The works of Eliot such as his primary essay “Tradition and the Individual Talent,” and his primary poems such as “The Love Song of J. Alfred Prufrock,” “Gerontion,” The Waste Land, “Ash Wednesday,” “A Song for Simeon” and Four Quartets are under scrutiny in this paper. Eliot’s primary texts echo the vision of the Upanishads, the Bhagavad-Gita and the Patanjali Yoga Sutras of the Hindu (Vedic) philosophy. The vision is that rebirth is conditioned by one’s karma (actions). No one can escape from the fruits of his karma. One needs to undergo the self-realization to know the Essence (Brahman). When one knows the Essence, he is liberated from the wheel of life and death. Man himself is Brahman. The soul is immortal. The basic essence of Hindu philosophy is non-dual, which says that all the living beings and non-living objects are the manifestations of the same Ultimate Reality (Brahman). Eliot suggests that the knowledge of this essence can help humanity to promote equality and justice by ignoring discrimination and duality, to end human sorrows and to achieve real peace and happiness. This finding can assist humanity in the quest for understanding the meaning of human existence and the true spiritual nature of life to address the human sorrows resulted from the gross materialistic thinking.

Physical Principles

A number of methods are available to quantify exterior size and shape of living and non-living objects. Relevant items for dentistry are the exterior of face and skull and the surface of dental casts. To the best of our knowledge, dentitions have not yet been measured in situ. The optical methods using incoherent light are mechanical sensing of casts, visual stereometry (on the subject or on stereophotographic pairs), moire techniques, and optical-sensor morphometry. It will be shown that the three latter systems in fact rely on the same physical principles, although they involve quite different technologies. On the other hand, coherent optical techniques, such as holography and contouring holographic interferometry, are presented. The basic principles of the different techniques are shown, and their main features in relation to applications to the dental object discussed. Main features include: resolving power, range, time needed for a measurement, requirements for the surface of the object, and ease of selection and collection of data. Examples of methods from the literature and from work by the author are given.
