On the practical feasibility of fair TCP communications in IEEE 802.11 based multihop ad hoc wireless networks [PDF]

open access: yes, 2005
In the center of this dissertation is the question whether it is practically feasible to achieve deterministically good quality for traditional network services such as file transfer and Web browsing in multihop wireless mobile ad hoc networks (MANETs ...

Hydrophilic Polymers Enable Gastrointestinal Transit Monitoring by Fluorine‐19 Magnetic Resonance Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic fluorinated copolymers dissolve in chyme and give a strong, single 19F signal, unlike phase‐separating perfluorocarbons. Combined 1H‐19F MRI tracks their whole‐gut transit non‐invasively and without ionizing radiation. In rats, the tracers move through the gastrointestinal tract, resist resorption, and are well tolerated, a proof‐of‐concept

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

open access: yesAdvanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

TCP goes to hollywood [PDF]

open access: yesProceedings of the 26th International Workshop on Network and Operating Systems Support for Digital Audio and Video, 2016
Real-time multimedia applications use either TCP or UDP at the\ud transport layer, yet neither of these protocols offer all of the features\ud required. Deploying a new protocol that does offer these features\ud is made difficult by ossification: firewalls, and other middleboxes,\ud in the network expect TCP or UDP, and block other types of traffic.\ud

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

open access: yesAdvanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Development of an Adaptive File Transfer Protocol (AFTP ) [PDF]

open access: yesEngineering and Technology Journal, 2011
File is one of the main storing units of information. There is a great need to transfer file through computer network especially the internet. The model that is used in Internet is the TCP-IP. The TCP-IP model consists of four layers. The lowest layer is

Resolving Nanoscale Heterogeneities in Lead Halide Perovskites Through Low‐Dose Concurrent 4D‐STEM‐EDX Mapping

open access: yesAdvanced Materials, EarlyView.
Mixed‐cation lead mixed‐halide perovskites suffer from structural instabilities linked to nanoscale heterogeneity. To probe this non‐destructively, a low‐dose, concurrent 4D‐STEM and EDX methodology has been developed. Examining a (FA0.83Cs0.17)Pb(I0.8Br0.2)3 film revealed a complex mosaic of coexisting crystal structures. Crucially, local deficiencies

Transport congestion events detection (TCED): towards decorrelating congestion detection from TCP [PDF]

open access: yes, 2010
TCP (Transmission Control Protocol) uses a loss-based algorithm to estimate whether the network is congested or not. The main difficulty for this algorithm is to distinguish spurious from real network congestion events.

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

open access: yesAdvanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Formation of delta-doped p-layer of hydrogen in natural and CVD-diamond crystals

open access: yesТехнологія та конструювання в електронній апаратурі, 2011
A method is proposed for the hydrogen heat treatment of natural and CVD-diamond crystals, which can serve as an alternative to conventional method of forming H-layer in microwave plasma of hydrogen as a simpler one and more reproducible.
