To exploit the parallelism of optics in data processing, a suitable number system and an efficient encoding/decoding scheme for handling the data are very essential. In the field of optical computing and parallel information processing, several number systems like binary, quaternary, octal, hexadecimal, etc. have been used for different arithmetic and algebraic operations. Here, we have proposed an all-optical conversion scheme from its binary to its other 2^n radix based form with the help of terahertz optical asymmetric demultiplexer （TOAD） based tree-net architecture.

An all-optical 2-to-4 decoder unit with the assist of terahertz optical asymmetric demultiplexer (TOAD) is presented. The all-optical 2-to-4 decoder with a set of all-optical switches is designed which can be used to achieve a high-speed central processor unit using optical hardware. The unique output lines can be used for all-optical header processing. We attempt to develop an integrated all-optical circuit which can perform decoding of signal. This scheme is very simple and flexible for performing different logic operation and to design advanced complex logic. Simulated results are confirming the described methods.

Potential toxicity of transition metals like Hg, Cu and Cd are well known and their affinity toward proteins is of great concern. This work explores the selective nature of interactions of Cu2＋, Hg2＋ and Cd2＋ with the heme proteins leghemoglobin, myoglobin and cytochrome C. The binding profiles were analyzed using absorbance spectrum and steady-state fluorescence spectroscopy. Thermodynamic parameters like enthalpy, entropy and free energy changes were derived by isothermal calorimetry and consequent binding parameters were compared for these heme proteins. Free energy （AG） values revealed Cu2＋ binding toward myoglobin and leghemoglobin to be specific and facile in contrast to weak binding for Hg2＋ or Cd2＋ . Time correlated single photon counting indicated significant alteration in excited state lifetimes for metal complexed myoglobin and leghemoglobin suggesting bimolecular collisions to be involved. Interestingly, none of these cations showed significant affinity for cytochrome c pointing that, presence of conserved sequences or heme group is not the only criteria for cation binding toward heme proteins, but the microenvironment of the residues or a specific folding pattern may be responsible for these differential conjugation profile. Binding of these cations may modulate the conformation and functions of these biologically important proteins.

Bus systems provide a versatile form of public transportation with the flexibility to serve a variety of access needs throughout an urban area. Efficient operation of the public transport is a key factor for the improvement of living condition in Dhaka city. Transport service performance should be assessed from the passengers’ perspectives to evaluate these perceptions in transportation planning. The exploration of service quality of bus is essential in order to provide a better service in future. The objective of this research is to access overall customer satisfaction in public bus transport of Dhaka city. A questionnaire survey was conducted in five locations in Dhaka city. Bus users’ satisfaction was analyzed by discrete choice logit model towards quality, reliability, safety and security and service provided by buses functioning in Dhaka city. The result indicated that more than half of the respondents believed that the present condition of bus service is not satisfactory. In case of the quality of buses, people think that the body and sitting arrangement of the buses are uncomfortable. Regarding the safety and security condition, main three reasons of dissatisfaction of passengers’ are unsafe driving practices, poor boarding and alighting facilities and lack of law enforcing agencies surveillance. Reasons which make the service unsatisfactory include irregular service provided by buses, regular overcrowding, lack of good standard buses and lack of cleanliness. In spite of these negative views, users’ possessed a positive attitude for buses which is the low travel cost.

Immunotherapies that aim to reactivate anti-tumor immune responses have revolutionized cancer treatment. However, the success of immunotherapy is also eclipsed by several grand challenges, including low response rate, intrinsic/acquired resistance, etc. Recent findings suggest that tumor immune infiltrates are highly heterogeneous among patients, very likely contributing to differential therapy outcomes. Therefore, characterizing and understanding such heterogeneity is critical to develop more effective immunotherapies for a wider range of patients. Here, we leveraged the power of single cell RNA-seq to characterize the tumor immune cell heterogeneity from a cohort of 25 melanoma patients and generated an unbiased map of the expression signatures of immune cells. In parallel, we also derived the T cell receptor sequences for single T cells, and determined intra-and inter-tumoral T cell clonality and inferred the functionality of clonally expanded T cell populations in the tumor. Different cell types and cellular states were observed, including na?ve, cytotoxic, dysfunctional, memory, and regulatory T cells, as well as various myeloid subsets. Notably, despite identical disease stage and treatment background, the composition of the immune cell populations differed considerably between patients. In addition, while analysis of T cell states showed high variability between patients, clonally expanded T cells predominantly adapted similar cell profiles. More importantly, by comparing the immune cell profiles between responders and non-responders and linking the single cell transcriptome to tumor recognition potential, we are able to identify the transcriptome signatures of T cells that are reactive to tumor and dictate the patient’s response to immunotherapy. In summary, our study generated an immune cell atlas of human melanoma, revealed the intra-and inter-patient heterogeneity of tumor immune infiltrates, and identified the transcriptome signature of T cells that are
