Diverse sets of complete human genomes are required to construct a pangenome reference and understand the extent complex structural variation. Here, we sequence 65 diverse build 130 haplotype-resolved assemblies (130 Mbp median continuity), closing 92% all previous assembly gaps reaching telomere-to-telomere (T2T) status for 39% chromosomes. We highlight continuity loci, including major histocompatibility (MHC), SMN1/SMN2, NBPF8, AMY1/AMY2, fully resolve 1,852 variants (SVs). In addition,...
Using a cylindrical phantom containing saline, the effects of extended layers in third dimension on two-dimensional tomographic images have been studied. Experimentally obtained magnitudes pixel values corresponding to different conditions are presented. Analysis these data brings out two phenomena: (i) changed resistivity electrode plane can appear as both increased and decreased image; (ii) position maximum change image occurs at increasing distances from edge phantom, introduced further...
The Focused Impedance Method (FIM) is a new technique of electrical bioimpedance measurements in the human body. idea originated Bangladesh and provides an opportunity for localized measurement down to reasonable depths from body surface using skin electrodes. This has potential applications physiological studies targeted organs detecting or diagnosing diseases disorders. FIM based on age-old Tetra-Polar Measurement (TPIM) but few significant improvements. Technology must be developed...
Mulo Village is one of the villages that has adopted concept CBT (Community-Based Tourism) as foundation for development tourist attractions. Community empowerment was chosen because management hopes or expects local community can play an active role in attractions and directly benefit from tourism. a strategic location potential natural resources, yet currently only two are developed: Ngingrong Cave Sewu Mountain Geopark Batu Park. Therefore, there still great to discover other with appeal....
When a breast lump is detected through palpation, mammography or ultrasonography, the final test for characterization of tumour, whether it malignant benign, biopsy. This invasive and carries hazards associated with any surgical procedures. The present work was undertaken to study feasibility such using non-invasive electrical impedance measurements machine learning techniques. Because changes in cell morphology benign tumours, are expected at fixed frequency, versus frequency measurement....
A simple and inexpensive water purification method was developed using natural coagulant (Moringa seed powder) antibacterial agents (scallop followed by bio-sand filtration. In this study, surface from different sources (e.g. pond, canal, lake river) treated with combined Moringa powder, scallop powder (MOSP) at a ratio of 2:1 for 10 minutes showed clear layer the top sediment bottom. The then passed through an eight-fold sari cloth and/or filtration resulting found drinkable....
A bstract : Conventional four‐electrode impedance measurements (FEIM) cannot localize a zone of interest in volume conductor. On the other hand, recently developed electrical tomography (EIT) system offers an image with reasonable resolution, but is complex and needs many electrodes. By placing two FEIM systems perpendicular to each over common at center combining results, it possible obtain enhanced sensitivity this central zone. This basis proposed new method focused measurement (FIM)....
One of the problems with tetrapolar impedance measurements is lack spatial sensitivity within measured volume. In this paper we compare and focused (FIM) proposed by Rabbani et al (1999 Ann. New York Acad. Sci. 873 408–20), which give an improved profile. Using a previously validated model based on Geselowitz's lead theory, FIM using eight, six four electrodes was investigated. All electrode configurations showed maximum in average plane at depth one-third drive–receive spacing. No...
Improvements in genome sequencing and assembly are enabling high-quality reference genomes for all species. However, the process is still laborious, computationally technically demanding, lacks standards reproducibility, not readily scalable. Here we present latest Vertebrate Genomes Project pipeline demonstrate that it delivers at scale across a set of vertebrate species arising over last ~500 million years. The versatile combines PacBio HiFi long-reads Hi-C-based haplotype phasing new...
Subcutaneous fat layer thickness in the abdomen is a risk indicator of several diseases and disorders like diabetes heart problems could be used as measure fitness. Skinfold measurement using mechanical calipers simple but prone to error. Ultrasound scanning techniques are yet established accurate methods for this purpose. magnetic resonance imaging (MRI) computed tomography (CT) scans can provide answer expensive not available widely. Some initiatives were made earlier use electrical...
Focused Impedance Method (FIM) based on 8, 6 and 4 electrode configurations have been innovated developed for measuring the electrical impedance of a localised zone in volume conductor, all tetrapolar technique. The localization FIM has visualized through equipotential distributions, current density at target point perturbation produced potential electrodes. predicted behaviour verified though phantom measurements analytical techniques by different groups. is particularly sensitive useful if...
Abstract This study was conducted to evaluate the effectiveness of a simplified, low cost, pasteurization device in inactivating diarrheal pathogens present pond/lake/river water order provide safe potable people living rural areas resource countries. In this process, polyethylene bags exposed sunshine, where UV radiation emissions and heat absorption from sunshine occurs simultaneously, maintaining heating at <60 °C, minimum 996.2 W/m2 for approximately 30 minutes found enough...
The present work was taken up to have an understanding of the depth sensitivity 6 electrode FIM developed by our laboratory earlier, so that it may be applied judiciously for measurement organs in 3D, with electrodes on skin surface. For a fixed geometry is expected depend depth, size and conductivity target object. With current 18 cm apart potential 5 apart, spherical conductors, insulators pieces potato different diameters were measured. dropped sharply gradually leveling off background,...
Conventional spirometry gives information on the overall ventilation of a person's lung; it cannot detect localized disorders in as occurring pulmonary edema, pneumonia, tumor, TB, etc. Here we propose new technique involving recently developed focused impedance method (FIM) combination with conventional to lung disorders. Electrical tissue changes function air content and FIM provides measurement electrical sensitivity down reasonable depths inside body using few surface electrodes; here...
Dynamic foot pressure measurement is necessary particularly for diabetic patients to prevent ulcers, eventually leading gangrene and amputation. The present work reports a low cost optical sensing system the above, suitable Third World. It uses horizontally placed transparent Acrylic plate with webcam below facing upwards. A white paper, backed by black adhesive plastic sheet, covered whole on top. Light from tubular fluorescent lamp entered acrylic side traversed thickness through total...
Conventional low cost leg prosthesis, available in Third World countries, is essentially a fixed passive structure which makes walking possible with some difficulty, and climbing stairs such extremely difficult. The present work was taken to design prosthesis for above-knee amputees. bionic has an active (battery powered) limited rotational movement of the knee joint, controlled by voluntary EMG (electromyogram) signals from two opposing muscles thigh; one rotate backward (flexion) other...
Abdominal fat thickness is a risk indicator of heart diseases, diabetes, etc., and its measurement therefore important from the point view preventive care. Tetrapolar electrical impedance measurements (TPIM) could offer simple low cost alternative for such compared to conventional techniques using CT scan MRI, has been tried by different groups. Focused Impedance Method (FIM) appears attractive as it can give localised information. An intuitive physical model was developed experimental work...
ECG equipment is vital for diagnosis of cardiac problems. However, such come from the rich Western countries at a huge cost in both procurement and maintenance, therefore cannot offer services to large population Third World countries. The only solution design develop individual by developing local expertise. With three decades experience, Dhaka University group has taken step towards prototypes dissemination healthcare service providers. This paper presents detailed an PC based where...
