أسطورة المال : سادة العالم وإدمان المخاطر
\"ذات يوم كان المجتمع الإنساني يبني أشياء.. كنا نصنع أشياء جميلة، وننتج سلعا متقنة. أما الآن، فقد أحللنا الهندسة المالية المتلونة محل الهندسة الصناعية الحقيقية ؛ حيث يتم خلط الأموال في عملية لانهائية من الدين والمتاجرة والمضاربة. وهو ما مكن فئة قليلة من تكوين ثروات طائلة بينما تحمل أناس عاديون نتائج مخاطرة «خصخصة المكاسب»، و«تعميم الخسائر» يروي كتاب «أسطورة المال» قصة ألعاب المال المذهلة والخطرة وأولئك المصرفيين والمتاجرين والممولين النخبويين أو من يسمون ب«سادة العالم» الذين يواصلون ممارستها، كما يوضح لنا هذا الكتاب الذي ألفه أحد العالمين ببواطن الأمور خطوة خطوة أننا جميعا أصبحنا مدمنين للكيمياء المالية القديمة ومفتونين بما صنعناه بأيدينا. وهو ما يطلق عليه المؤلف : إدمان التمويل العالمي. قالوا عن الكتاب : يقدم المؤلف تحليلا مدمرا لا يصدر إلا عن عالم ببواطن الأمور بحق فيما يخص الكيمياء المالية القديمة على مدى الأعوام الثلاثين الماضية، وعواقبها الوخيمة؛ حيث يتمتع ساتياجيت داس بمعرفة مباشرة عميقة، وكأنه يعمل سكينا في التمويل والممولين العالميين ليكشف لنا خبايا وأسرار أساليب عملهم بلا خوف أو تحيز\"\"، أستاذ الإقتصاد بكلية ستيرن للأعمال في جامعة نيويورك، نورييل روبيني ورئيس مجلس إدارة روبيني جلوبال إيكونوميكس، يشرح ساتياجيت داس أسباب الأزمة المالية ببصيرة وهم عراف مالي، وصراحة وموضوعية مراقب محايد، وروح دعابة ساخرة وظريفة تكشف مدى ما ينطوي عليه الأمر كله من حماقة، رئيس مجلس الإدارة السابق للجنة الأمريكية لتداول عمليات التسليم بروكسلي بورن الآجل للسلع.\".

Strong, lightweight, and recoverable three-dimensional ceramic nanolattices
Ceramics have some of the highest strength- and stiffness-to-weight ratios of any material but are suboptimal for use as structural materials because of their brittleness and sensitivity to flaws. We demonstrate the creation of structural metamaterials composed of nanoscale ceramics that are simultaneously ultralight, strong, and energy-absorbing and can recover their original shape after compressions in excess of 50% strain. Hollow-tube alumina nanolattices were fabricated using two-photon lithography, atomic layer deposition, and oxygen plasma etching. Structures were made with wall thicknesses of 5 to 60 nanometers and densities of 6.3 to 258 kilograms per cubic meter. Compression experiments revealed that optimizing the wall thickness-to-radius ratio of the tubes can suppress brittle fracture in the constituent solid in favor of elastic shell buckling, resulting in ductile-like deformation and recoverability.

A linear matric inequality based multi-loop PI control design for coupled multivariable liquid level system
This paper presents design and development of an optimal robust PI controller based on linear matrix inequalities for a typical industrial process control system. In this method, the design problem has been transformed into a state feedback controller design problem for an augmented uncertainty MIMO system. In this work, a dynamic decoupler is designed to handle loop interaction. The control problem is then solved for the obtained decoupled subsystem by employing a constraint optimization approach, ensuring compliance with a defined LQ cost objective function. Simulation results verify the efficacy of the proposed controller, presenting its effectiveness in achieving both set-point accuracy and disturbance attenuation. Furthermore, the study employs disk margin analysis to ascertain safe ranges for gain and phase margin.

An assessment of suitable landfill site selection for municipal solid waste management by GIS-based MCDA technique in Siliguri municipal corporation planning area, West Bengal, India
Identification of suitable landfill sites for urban wastes with ease and economic benefits in the metropolitan area is a complex task. Most of the developing countries consider wastelands outside of the urban areas are the ideal places to dispose of urban wastes. Landfill site selection is an essential planning procedure that helps to avoid environmental concerns such as water contamination, public health degradation caused by unsanitary landfills. So, employing a geographic information system (GIS) and multi-criteria decision analysis (MCDA), this study was carried out to find an appropriate planning waste dump site. Nine thematic layers were evaluated as key criteria, including elevation, slope, geology, lineament, land value, distance from river, roads, residence, and Land use and land cover (LULC) weights assigned using Analytical Hierarchical Process (AHP) method analysis. The relative relevance of each parameter was calculated using Saaty’s 1 to 9 priority scale. The consistency ratio was used to check the weighting of each parameter, allowing the efficiency of the chosen parameters to be justified. The overlay analysis of all parameters with aid of GIS provides suitable sites that were marked and refined after the comprehensive field visits were performed. According to the findings, in the study area, 35.61% area is very low suitable for landfilling, 32.64% area is low suitable, 19.37% area is moderate suitable, 8.90% area is highly suitable and certainly, 3.48% area is very high suitable by Natural breaks classification. The very high suitable site belongs to Dhadagoch, Gadheaganj, and its surroundings in the study area. Nevertheless, the present study can help urban planners and concerned authorities to better succeed in urban waste management in the Siliguri municipal corporation planning area.

Sheet Resistance Measurements of Conductive Thin Films: A Comparison of Techniques
Conductive thin films are an essential component of many electronic devices. Measuring their conductivity accurately is necessary for quality control and process monitoring. We compare conductivity measurements on films for flexible electronics using three different techniques: four-point probe, microwave resonator and terahertz time-domain spectroscopy. Multiple samples were examined, facilitating the comparison of the three techniques. Sheet resistance values at DC, microwave and terahertz frequencies were obtained and were found to be in close agreement.

Floating Point CGRA based Ultra-Low Power DSP Accelerator
Coarse Grained Reconfigurable Arrays (CGRAs) are emerging as energy efficient accelerators providing a high grade of flexibility in both academia and industry. However, with the recent advancements in algorithms and performance requirements of applications, supporting only integer and logical arithmetic limits the interest of classical/traditional CGRAs. In this paper, we propose a novel CGRA architecture and associated compilation flow supporting both integer and floating-point computations for energy efficient acceleration of DSP applications. Experimental results show that the proposed accelerator achieves a maximum of 4.61× speedup compared to a DSP optimized, ultra low power RISC-V based CPU while executing seizure detection, a representative of wide range of EEG signal processing applications with an area overhead of 1.9×. The proposed CGRA achieves a maximum of 6.5× energy efficiency compared to the single core CPU. While comparing the execution with the multi-core CPU with 8 cores, the proposed CGRA achieves up to 4.4× energy gain.

Apoplastic reactive oxygen species mediated escape growth of root during illumination in Vigna radiata (L.) Wilczek seedlings
Besides gravity, roots are also guided by light to grow deep into the soil and sensitivity of roots to light is evidently due to presence of photoreceptors like phototropins. Such light-induced root growth (light-escape growth) presumably involves reactive oxygen species (ROS). Present study explores the possibility of ROS action in this event during early seedling growth of Vigna radiata based on pharmacological evidences. Germinated (20 h) seeds were incubated in dark or light in presence of general ROS scavenger (propyl gallate), specific scavengers of O2·- (copper chloride; CuCl2), H2O2 [dimethylthiourea (DMTU) and potassium iodide (KI)] and ˙OH (sodium benzoate) and ROS-producing enzyme inhibitors [zinc chloride (ZnCl2), inhibitor of NADPH oxidase (NOX); diethyldithiocarbamate (DEDTC), inhibitor of superoxide dismutase (SOD) and salicylhydroxamic acid (SHAM), inhibitor of peroxidase]. Light-induced root growth of 3-day seedlings diminished significantly in case of all the treatments suggesting for a positive role of ROS in light-escape growth. This is supported by elevated level of apoplastic ROS in light grown roots as evident from ROS-specific staining [nitroblue tetrazolium chloride (NBT) for O2·- and 3,3,5,5-tetramethylbenzidine (TMB) for H2O2] and spectrophotometric estimation of apoplastic ROS production ( O2·- and H2O2). In addition, higher activity of membrane bound NOX (producing O2·- ) and apoplastic class III peroxidase (Prx, producing ˙OH) in light grown roots further corroborates the view that apoplastic ROS (initiated with NOX-generated O2·- , which is converted, either spontaneously or by the activity of SOD, to H2O2 and further metabolized by Prx to ˙OH that participates in cell wall relaxation required for growth) is instrumental in light-escape growth of roots.

Avoid Maximum Cost Method for Solving Linear Fractional Transshipment Problem
This study contributes valuable insights into linear fractional transshipment problem which is a special class of mathematical programming problem. We present the mathematical model for the linear fractional transshipment problem and develop an efficient algorithm based on the 'Avoid Maximum Cost Method (AMCM)' for finding an initial basic feasible solution (IBFS) of the given model. AMCM is based on the concept of making the maximum possible allocation to either a column or a row of the transportation cost matrix in such a way that the allocation to the corresponding cell that has the highest cost will be avoided in the further steps. The methodology is composed of the following two steps: firstly, we formulated an equivalent transportation model of the problem by considering the cost-profit ratio matrix. Secondly, we apply AMCM to find an IBFS of the problem. In a nutshell, this article finds the solution to a linear fractional transshipment model by applying AMCM to the cost-profit ratio matrix. The applicability of the proposed approach is illustrated with some suitable numerical examples. The contribution ends by introducing a comparative analysis to show the efficiency of the proposed algorithm.
