Experimental study of transversal-stress-induced polarization crosstalk behaviors in polarization maintaining fibers (2019)

For the first time, we experimentally study the transversal-stress (T-stress) induced polarization crosstalk behaviors in polarization maintaining fibers (PMFs) including the linearity, sensitivity, response time and recovery time, using a distributed polarization crosstalk analysis (DPXA) system. Using two Panda PMFs with or without polyacrylate buffer coating and one Bow-tie PMF with golden polyimide coating as experimental samples, we find that: I) the polarization crosstalk can be highly linear with the T-stress for PMFs no matter with or without coating; II) the polyacrylate coating can reduce the crosstalk sensitivity of naked PMFs by more than hundreds of times, while replacing the polyacrylate coating with polyimide coating can increase the sensitivity by tens or even hundreds of times; III) the polyacrylate coating can induce a significant recovery time of crosstalk when a T-stress is removed after a long loading time compared with that in naked PMFs or golden PMF with polyimide coating, however the crosstalk response speed is too fast to be measured by the DPXA system. Additionally, we also find that the current polyimide coating technique still needs to be improved further to reduce the crosstalk base level. This work will be very useful for PMF-based distributed sensing applications and sensing PMF manufacturing.
The influence of different lipid environments on the structure and function of the hepatitis C virus p7 ion channel protein (2011)

Abstract The hepatitis C virus (HCV) encodes the p7 protein that oligomerizes to form an ion channel. The 63 amino acid long p7 monomer is an integral membrane protein predominantly found in the endoplasmic reticulum (ER). Although it is currently unknown whether p7 is incorporated into secreted virions, its presence is crucial for the release of infectious virus. The molecular and biophysical mechanism employed by the p7 ion channel is largely unknown, but in vivo it is likely to be embedded in membranes undergoing changes in lipid composition. In this study we analyze the influence of the lipid environment on p7 ion channel structure and function using electrophysiology and synchrotron radiation circular dichroism (SRCD) spectroscopy. We incorporated chemically synthesized p7 polypeptides into artificial planar membranes of various lipid compositions. A lipid bilayer composition comprising phosphatidylcholine (PC) and phosphatidylethanolamine (PE) (4:1 PC:PE) led to burst-like patterns in the channel recordings with channel openings lasting up to 0.5 s. The reverse ratio of PC:PE (1:4) gave rise to individual channels continuously opening for up to 8 s. SRCD spectroscopy of p7 embedded into liposomes of corresponding lipid compositions suggests there is a structural effect of the lipid composition on the p7 protein.

Jointly Resampling and Reconstructing Corrupted Images for Image Classification using Frequency-Selective Mesh-to-Grid Resampling (2022)

Neural networks became the standard technique for image classification throughout the last years. They are extracting image features from a large number of images in a training phase. In a following test phase, the network is applied to the problem it was trained for and its performance is measured. In this paper, we focus on image classification. The amount of visual data that is interpreted by neural networks grows with the increasing usage of neural networks. Mostly, the visual data is transmitted from the application side to a central server where the interpretation is conducted. If the transmission is disturbed, losses occur in the transmitted images. These losses have to be reconstructed using postprocessing. In this paper, we incorporate the widely applied bilinear and bicubic interpolation and the high-quality reconstruction Frequency-Selective Reconstruction (FSR) for the reconstruction of corrupted images. However, we propose to use Frequency-Selective Mesh-to-Grid Resampling (FSMR) for the joint reconstruction and resizing of corrupted images. The performance in terms of classification accuracy of EfficientNetB0, DenseNet121, DenseNet201, ResNet50 and ResNet152 is examined. Results show that the reconstruction with FSMR leads to the highest classification accuracy for most networks. Average improvements of up to 6.7 percentage points are possible for DenseNet121.
Volatolomics in healthcare and its advanced detection technology (2022)

Various diseases increasingly challenge the health status and life quality of human beings. Volatolome emitted from patients has been considered as a potential family of markers, volatolomics, for diagnosis/screening. There are two fundamental issues of volatolomics in healthcare. On one hand, the solid relationship between the volatolome and specific diseases needs to be clarified and verified. On the other hand, effective methods should be explored for the precise detection of volatolome. Several comprehensive review articles had been published in this field. However, a timely and systematical summary and elaboration is still desired. In this review article, the research methodology of volatolomics in healthcare is critically considered and given out, at first. Then, the sets of volatolome according to specific diseases through different body sources and the analytical instruments for their identifications are systematically summarized. Thirdly, the advanced electronic nose and photonic nose technologies for volatile organic compounds (VOCs) detection are well introduced. The existed obstacles and future perspectives are deeply thought and discussed. This article could give a good guidance to researchers in this interdisciplinary field, not only understanding the cutting-edge detection technologies for doctors (medicinal background), but also making reference to clarify the choice of aimed VOCs during the sensor research for chemists, materials scientists, electronics engineers, etc.
Dynamic Display of BRDFs (2011)

Abstract This paper deals with the challenge of physically displaying reflectance, i.e., the appearance of a surface and its variation with the observer position and the illuminating environment. This is commonly described by the bidirectional reflectance distribution function (BRDF). We provide a catalogue of criteria for the display of BRDFs, and sketch a few orthogonal approaches to solving the problem in an optically passive way. Our specific implementation is based on a liquid surface, on which we excite waves in order to achieve a varying degree of anisotropic roughness. The resulting probability density function of the surface normal is shown to follow a Gaussian distribution similar to most established BRDF models.
Metastable liquid-liquid and solid-liquid phase boundaries in polymer-solvent-nonsolvent systems (1997)

In general liquid–liquid demixing processes are responsible for the porous morphology of membranes obtained by immersion precipitation. For rapidly crystallizing polymers, solid–liquid demixing processes also generate porous morphologies. In this study, the interference of both phase transitions has been analyzed theoretically using the Flory–Huggins theory for ternary polymer solutions. It is demonstrated that four main thermodynamic and kinetic parameters are important for the structure formation in solution: the thermodynamic driving force for crystallization, the ratio of the molar volumes of the solvent and the nonsolvent, the polymer–solvent interaction parameter, and the rate of crystallization of the polymer compared to the rate of solvent-nonsolvent exchange. An analysis of the relevance of each of these parameters for the membrane morphology is presented. © 1997 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 35: 763–770, 1997
Biallelic TLR4 deficiency in humans (2022)

Biallelic TLR4 deficiency in humans causes an inborn error of immunity in responding to LPS. This complements the spectrum of known primary immunodeficiencies, in particular myeloid differentiation primary response 88 (MYD88) or the IL-1 receptor-associated kinase 4 (IRAK4) deficiency that are downstream of TLR4 and TLR2 signaling.
The Stingy Shift Explained as a Majority Rule Equilibrium (1977)

[Introduction] Baron, Roper and Baron (1974) claim that group decisions regarding contributions to a charitable cause sometimes represent generally stingier options than the options picked by individuals when choosing alone. Their study and interpretations are consistent with a sizable social psychological literature which postulate:o; that "choice shifts" of various kinds occur as a result of group decision. Theories used to explain "choice shifts" usually rest on principles of group decision involving concepts like cultural values, responsibility, leadership, etc. In the present case, for example, the diffusion of personal responsibility for uncharitable behavior was offered as one explanation for smaller mean donations by groups.
Surfactant‐Free Scalable Synthesis of Bi2Te3 and Bi2Se3 Nanoflakes and Enhanced Thermoelectric Properties of Their Nanocomposites (Adv. Mater. 10/2013) (2013)

Nanomaterial-based thermoelectric devices request scalable production and compositional tolerance for reliable device performance. On page 1425 Unyong Jeong and co-workers suggest a large-quantity synthesis of surfactant-free nanoflakes of Bi2Te3 and Bi2Se3. The chemical composition of the heterostructured nanocomposites is precisely controlled by mixing the nanoflake suspensions. A maximum ZT (0.7 at 400 K) is achieved with a broad content of 10–15% Bi2Se3 in the nanocomposites.

Pathogenesis ofAspergillus fumigatusin Invasive Aspergillosis (2009)

Aspergillus species are globally ubiquitous saprophytes found in a variety of ecological niches. Almost 200 species of aspergilli have been identified, less than 20 of which are known to cause human disease. Among them, Aspergillus fumigatus is the most prevalent and is largely responsible for the increased incidence of invasive aspergillosis (IA) in the immunocompromised patient population. IA is a devastating illness, with mortality rates in some patient groups reaching as high as 90%. Studies identifying and assessing the roles of specific factors of A. fumigatus that contribute to the pathogenesis of IA have traditionally focused on single-gene deletion and mutant characterization. In combination with recent large-scale approaches analyzing global fungal responses to distinct environmental or host conditions, these studies have identified many factors that contribute to the overall pathogenic potential of A. fumigatus. Here, we provide an overview of the significant findings regarding A. fumigatus pathogenesis as it pertains to invasive disease.

Deadbeat-direct torque & flux control motor drive over a wide speed, torque and flux operating space using a single control law (2010)

This paper presents an implementation of deadbeat-direct torque and flux control (DB-DTFC) for AC induction machine drives that demonstrates nearly ideal properties over a wide range of flux and torque operating conditions, including deep field weakening. A key attribute of this DB-DTFC is that the control law is the same over the entire operating space, including steady-state and transient operation at the voltage limits. By comparison, field oriented control at the voltage limit is inherently compromised and requires adjustment of the current control laws. Similarly, PI control-based DTFC becomes oscillatory under voltage limit conditions. This DB-DTFC implementation requires no change to the control law under voltage limit conditions. This paper presents an implementation of DB-DTFC and experimentally demonstrates its performance over a full range of operating conditions, including operation at the voltage limit.
Design Space Exploration of Power Delivery For Advanced Packaging Technologies (2020)

In this paper, a design space exploration of power delivery networks is performed for multi-chip 2.5-D and 3-D IC technologies. The focus of the paper is the effective placement of the voltage regulator modules (VRMs) for power supply noise (PSN) suppression. Multiple on-package VRM configurations have been analyzed and compared. Additionally, 3D IC chip-on-VRM and backside-of-the-package VRM configurations are studied. From the PSN perspective, the 3D IC chip-on-VRM case suppresses the PSN the most even with high current density hotspots. The paper also studies the impact of different parameters such as VRM-chip distance on the package, on-chip decoupling capacitor density, etc. on the PSN.

Phosphates form spectroscopically dark state assemblies in common aqueous solutions (2022)

Phosphates and polyphosphates play ubiquitous roles in biology as integral structural components of cell membranes and bone, or as vehicles of energy storage via adenosine triphosphate and phosphocreatine. The solution phase space of phosphate species appears more complex than previously known. We present nuclear magnetic resonance (NMR) and cryogenic transmission electron microscopy (cryo-TEM) experiments that suggest phosphate species including orthophosphates, pyrophosphates, and adenosine phosphates associate into dynamic assemblies in dilute solutions that are spectroscopically "dark." Cryo-TEM provides visual evidence of the formation of spherical assemblies tens of nanometers in size, while NMR indicates that a majority population of phosphates remain as unassociated ions in exchange with spectroscopically invisible assemblies. The formation of these assemblies is reversibly and entropically driven by the partial dehydration of phosphate groups, as verified by diffusion-ordered spectroscopy (DOSY), indicating a thermodynamic state of assembly held together by multivalent interactions between the phosphates. Molecular dynamics simulations further corroborate that orthophosphates readily cluster in aqueous solutions. This study presents the surprising discovery that phosphate-containing molecules, ubiquitously present in the biological milieu, can readily form dynamic assemblies under a wide range of commonly used solution conditions, highlighting a hitherto unreported property of phosphate's native state in biological solutions.
Unified approach for the calculation of force constants and accelerated convergence of atomic coordinates (1996)

A method which simultaneously computes the force-constant matrix (FCM) and relaxes the atomic coordinates to the ground state of a generic system is introduced. The method is based on the optimization of the FCM as the atomic coordinates evolve to their ground-state configuration, using the variations in atomic positions and forces from previous iterations as inputs. Striking accelerated convergence as compared to traditional methods is obtained, as well as accurate vibrational frequencies with no additional cost. \textcopyright{} 1996 The American Physical Society.

Biological Fuel Cells for Biomedical Applications (2014)

An implantable medical device (IMD) operates inside the body to monitor certain physiological parameters. A fuel cell capable of harvesting electrical energy while operating in vivo is a promising alternative electric power source. In contrast to a battery, fuel cells rely on reactants being introduced to the system, reactions occurring in the cell compartment, and products being released from it, which adds complexity to the biocompatibility criteria. This chapter discusses existing classifications of biodevices and decides what types of biological fuel cell (BFC) designs are feasible to be used for powering IMDs. Different types of BFCs based on different biocatalysts, such as whole living cells, organelles, or isolated redox proteins and enzymes, have their own advantages and disadvantages, are described. The chapter focuses on the design and development of enzymatic fuel cells (EFCs), with special attention given to their biomedical applications.
Laparoscopic splenopexy for adult wandering spleen: sandwich method with two sheets of absorbable knitted mesh. (2000)

Wandering spleen is a rare entity with a constant danger of splenic torsion leading to splenomegaly and infarction, which requires surgery. The authors describe a 30-year-old woman with intermittent left hypochondralgia and back pain with wandering spleen, who was successfully treated with a new method of laparoscopic splenopexy. In this procedure, two sheets of absorbable knitted mesh were used to sandwich the detorsed spleen. The procedure is feasible and less invasive, without impaired splenic function, and is applicable even for adult splenomegalic wandering spleen.

Microscopic reversal behavior of magnetically capped nanospheres (2010)

The magnetic switching behavior of Co/Pd multilayer-capped nanospheres is investigated by x-ray spectro-holography. Images of the magnetic state of individual nanocaps are recorded as a function of externally applied magnetic field and the angle under which the field is applied, pertaining to magnetic data storage applications with patterned, tilted, and perpendicular storage media. Dispersed nanospheres with different coverage in the submonolayer regime are investigated simultaneously in a multiplexed experiment. In clustered nanosphere arrangements, we find that individual switching events are influenced by dipolar magnetostatic interactions. Micromagnetic simulations of the switching behavior complement the experimental observations, corroborating the influence of thermal activation processes and magnetostatic interactions in this system. Such magnetostatic interactions could lead to undesired cross-talk between bits in ultrahigh-density magnetic recording applications.

In addition, complex 1a shows a “quasi-living” polymerization behavior.
Categorization of Program Regions for Agile Compilation using Machine Learning and Hardware Support (2019)

A compiler processes the code written in a high level language and produces machine executable code. The compiler writers often face the challenge of keeping the compilation times reasonable. That is because aggressive optimization passes which potentially will give rise to high performance are often expensive in terms of running time and memory footprint. Consequently the compiler designers arrive at a compromise where they either simplify the optimization algorithm which may decrease the performance of the produced code, or they will restrict the optimization to the subset of the overall input program in which case large parts of the input application will go un-optimized. The problem we address in this paper is that of keeping the compilation times reasonable, and at the same time optimizing the input program to the fullest extent possible. Consequently, the performance of the produced code will match the performance when all the aggressive optimization passes are applied over the entire input program.
