Application of FTIR Spectroscopy for the Quantification of Sugars in Mango Juice as a Function of Ripening (2002)

FTIR-ATR spectroscopy and multivariate analysis were used for quantification of sugars in mango juices as a function of ripening. Calibration was based on sucrose/glucose/fructose mixtures, with six concentration levels and following a triangular experimental design. PLS1 regression of the spectra first derivatives gave the best results, enabling quantification of fructose, sucrose, and glucose with 1.4, 1.4, and 4.9% prediction errors, respectively. Throughout ripening, sucrose and fructose were accurately quantified by PLS-FTIR, whereas the accuracy of glucose determination decreased at later stages, when concentrations fell to 0.6-1.5 g/L. These results enabled a correlation with fruit ripening stage to be established. This may be particularly useful to detect over-ripening in fresh fruits, a period when other indicators (pH and % soluble solids (SS)) do not change significantly; this knowledge may help in predicting fruit stability to transport and storage. Similar information obtained for nonfresh juices (in which pH and %SS may be masked by additives), may help determine whether the source fruits had suitable ripening stages.
The Action of Hydrogen Bromide and Oxygen on Various Ethenoid Compounds. II (1956)

Abstract (1) The reaction of diphenylethylene, atropic acid, and styrene with the mixture of hydrogen bromide and oxygen were studied. In the case of diphenylethylene, diphenylbromomethane, ω-bromoacetophenone, diphenylethylene dibromide, phenol and carbon dioxide were obtained as reaction products. A reaction mechanism was proposed to explain how these compounds were produced. (2) In the case of atropic acid, a large amount of α-hydroxy-β-bromohydratopic acid and a small amount of ω,ω-dibromoaceto phenone and of carbon dioxide were obtained. A consideration on the mechanism of the formation of these products was given on the basis of the identified products and their semiquantitative estimation. (3) Addition of hydrogen bromide to atropic was carried out under various conditions. No reversal of the direction of addition of hydrogen bromide was observed contrary to the previous reference. (4) The reaction of styrene with the mixture of hydrogen bromide and oxygen added an example yielding a phenolic substance ia the reaction.
DSSylation, a novel protein modification targets proteins induced by oxidative stress, and facilitates their degradation in cells (2014)

Timely removal of oxidatively damaged proteins is critical for cells exposed to oxidative stresses; however, cellular mechanism for clearing oxidized proteins is not clear. Our study reveals a novel type of protein modification that may play a role in targeting oxidized proteins and remove them. In this process, DSS1 (deleted in split hand/split foot 1), an evolutionally conserved small protein, is conjugated to proteins induced by oxidative stresses in vitro and in vivo, implying oxidized proteins are DSS1 clients. A subsequent ubiquitination targeting DSS1-protein adducts has been observed, suggesting the client proteins are degraded through the ubiquitin-proteasome pathway. The DSS1 attachment to its clients is evidenced to be an enzymatic process modulated by an unidentified ATPase. We name this novel protein modification as DSSylation, in which DSS1 plays as a modifier, whose attachment may render target proteins a signature leading to their subsequent ubiquitination, thereby recruits proteasome to degrade them.
Monolithically integrated InGaAsP/InP composite-cavity distributed feedback lasers (1989)

Linewidth reduction to 1 MHz for monolithically integrated extended-cavity DFB lasers that are designed to achieve high optical coupling to a low-loss extended cavity is described. Since a high-efficiency extended cavity at the same time degrades the frequency-modulation (FM) response, an active gain section is integrated at the end of the extended cavity, and its use as a modulator section that maintains a flat FM response at 0.7 GHz/mA is shown. The linewidth and FM characteristics of this DFB extended-passive/active-cavity laser are compared to those of the conventional DFB extended-passive-cavity laser and a two-section DFB laser.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Low-Precision Neural Network Decoding of Polar Codes (2019)

Neural Network (NN) polar decoders have been getting much attention as a viable replacement for conventional decoders in 5G New Radio (NR). Despite scalability issues, the NN-based decoder is a promising technology as it can improve the latency of the standard Successive Cancellation (SC) decoder. It was shown that the Neural Successive Cancellation (NSC) decoder has an improved theoretical latency compared to the standard SC decoder. However, in contrast to SC, the NSC decoder uses large floating-point weight matrices which do not fit in CPU caches, leading to higher energy usage and lower computational performance due to the increased memory traffic. Additionally such higher memory requirement would be expensive to implement in hardware and require complex floating-point arithmetic. This paper presents a new low-precision NN decoder that can replace memory-heavy NN decoders inside the NSC decoder. We show that up to 54 times weights' size reduction can be achieved with the wireless performance degradation varying between 0.1dB and 0.4dB compared to the floating-point implementation. Moreover, we show a reduction of up to respectively 438× and 555× in L1 and L2 data cache misses in our prototype software implementation.

The two new platinum complexes described here appear to have an effective antitumour activity without severe toxicity when tested on Wistar rats.
Fabrication of a platform to isolate the influences of surface nanotopography from chemistry on bacterial attachment and growth (2015)

Billions of dollars are spent annually worldwide to combat the adverse effects of bacterial attachment and biofilm formation in industries as varied as maritime, food, and health. While advances in the fabrication of antifouling surfaces have been reported recently, a number of the essential aspects responsible for the formation of biofilms remain unresolved, including the important initial stages of bacterial attachment to a substrate surface. The reduction of bacterial attachment to surfaces is a key concept in the prevention or minimization of biofilm formation. The chemical and physical characteristics of both the substrate and bacteria are important in understanding the attachment process, but substrate modification is likely the most practical route to enable the extent of bacterial attachment taking place to be effectively controlled. The microtopography and chemistry of the surface are known to influence bacterial attachment. The role of surface chemistry versus nanotopography and their interplay, however, remain unclear. Most methods used for imparting nanotopographical patterns onto a surface also induce changes in the surface chemistry and vice versa. In this study, the authors combine colloidal lithography and plasma polymerization to fabricate homogeneous, reproducible, and periodic nanotopographies with a controllable surface chemistry. The attachment of Escherichia coli bacteria onto carboxyl (plasma polymerized acrylic acid, ppAAc) and hydrocarbon (plasma polymerized octadiene, ppOct) rich plasma polymer films on either flat or colloidal array surfaces revealed that the surface chemistry plays a critical role in bacterial attachment, whereas the effect of surface nanotopography on the bacterial attachment appears to be more difficult to define. This platform represents a promising approach to allow a greater understanding of the role that surface chemistry and nanotopography play on bacterial attachment and the subsequent biofouling of the surface.
Are photos on Social Networks really private? (2013)

Everyday, people upload thousand of private photos on Social Networks. Usually, these photos are available only to their social friends but, in some cases, users inadvertently allow third-party applications to access their data or, analogously, friends allow applications to access their friends' data. Hence, uploaded private pictures may also be accessed by third parties. In this paper, we introduce Phook (Photo-Book), which is a Web application available at www.myphook.com, aimed at searching among users' photos of online Social Network. After two months of activity, Phook was capable of collecting more than 70 Millions private pictures of Facebook users.
Aminomethylenephosphinic acids and their complexing properties (1992)

A study of the dependence of the 1H, 31P and 13C NMR spectra of D2O solutions of piperidinomethylphosphinic acid (HL1) and piperazine-1,4-diylbis(methylene)bis(phosphinic acid)(H2L2) on the pH has indicated a strong acidity of the phosphinic groups and a low basicity of the nitrogen atoms. It is confirmed that the acids from zwitterions in aqueous solution and that the HL1 ring behaves similarly to the N-methylpiperidine ring. The stability constants of complexes formed with Mg2+, Ca2+, Pb2+, Co2+, Ni2+, Cu2+, Cd2+ and Zn2+ are lower than those of their acetic or phosphonic acid analogues. In the solid state, HL1·H2O exists as a zwitterion, monoclinic, space group P21/n, a= 6.884(2), b= 11.485(2), c= 11.994(2)Å and β= 97.87(2)°. Two molecules are linked by hydrogen bonds into dimers which are connected by water molecules to form endless chains.
The bird is the word (2017)

Passwords still represent an annoying burden for millions of Internet users. Helping people create memorable and secure credentials is therefore an important goal for web-service providers to satisfy user needs. Due to the good memorability of pictures, emojis may be a suitable tool to create memorable and secure passwords. These small pictograms have seen an enormous rise in recent years, but their usage in regular passwords has not been explored for the Web. In a two-part user study with 40 participants we investigated if and how emojis are suitable in this context. We asked users to create passwords that contained both regular alphanumeric characters and emojis. The study shows that users' primary selection strategy was to create meaningful relationships between the emoji and the rest of the password. We also found that platform dependent renderings of emojis do not necessarily reduce usability, if the object represented by the emoji is distinctive enough. As websites are already starting to allow emojis in passwords, it is important to evaluate this step carefully. Our results can inform this decision and provide pointers to the usability implications.
The formation, identification, and significance of DNA-protein cross-links in mammalian cells. (1987)

DNA-protein cross-links (DPC) are formed by a variety of radiations and chemicals which act via free radical formation. Covalency is inferred from the resistance of the cross-links to harsh treatments. In mammalian cells, a background of DPC (6000 per V79 cell) may result from normal associations of chromosomal loops with the nuclear protein matrix. After ionizing radiation, the elevated level of DPC (150 per Gy per V79 cell) are enriched in actively transcribing DNA and in a subset of proteins of the nuclear matrix. DPC formation is reduced by hydroxyl radical scavengers, by oxygen, and by hypertonic medium and is enhanced by hypotonic medium and by removal of intracellular glutathione. DPC are repaired more slowly than single-strand breaks and not at all when formed during metaphase. During the postirradiation period, changes in the sequence composition of the DNA of residual DPC are consistent with the preferential repair of DPC in actively expressed genes. Excision repair mechanisms have been proposed. Unrepaired DPC may block normal functions of the nuclear matrix, such as replication and transcription.
Measurement verification of estimation method for time errors in a time-interleaved A/D converter system (2003)

A previously presented method for estimation of time errors in time-interleaved A/D converter systems is here verified on measurements from a dual A/D converter system. The advantage of this estimation method, compared to other methods, is that it does not require any knowledge about the input signal. The estimation is most accurate for slowly varying input signals but the signal quality is improved even when the estimation is done for a sinusoidal signal close to the Nyquist frequency.
Abstract P6-11-01: Cost-effectiveness of pertuzumab in HER2+ metastatic breast cancer (2016)

Abstract Purpose The Clinical Evaluation of Pertuzumab and Trastuzumab (CLEOPATRA) study showed a 15.7-month survival benefit with the addition of pertuzumab (P) to docetaxel and trastuzumab (TH) as first-line treatment for patients with HER2 overexpressing metastatic breast cancer. We performed a cost-effectiveness analysis to assess the value of the addition of pertuzumab to docetaxel and trastuzumab. Patient and Methods We developed a decision-analytic Markov model to evaluate the cost-effectiveness of TH with or without P in U.S. patients with metastatic breast cancer. The model followed patients weekly over their remaining lifetimes. Health states included: stable disease, progressing disease, hospice, and death. Transition probabilities were based on the CLEOPATRA study. Costs reflected the 2014 Medicare rates. Health state utilities were the same as those used in other recent cost-effectiveness studies of trastuzumab and pertuzumab. Outcomes included health benefits expressed as discounted quality-adjusted life-years (QALYs), costs in U.S. dollars, and cost-effectiveness expressed as an incremental cost-effectiveness ratio. One-way and multi-way deterministic and probabilistic sensitivity analyses explored the effects of specific assumptions. Results Modeled median survival was 39.4 months (TH) and 56.9 months (THP). The addition of pertuzumab resulted in an additional 1.81 life years gained (0.62 QALYs) at a cost of $472,668 per QALY gained. Deterministic sensitivity analysis showed that THP is unlikely to be cost-effective even under the most favorable assumptions, and probabilistic sensitivity analysis predicted 0% chance of cost-effectiveness at a willingness-to-pay of $100,000 per QALY gained. Conclusion The addition of pertuzumab to docetaxel and trastuzumab in patients with metastatic HER2+ breast cancer is unlikely to be cost-effective in the United States.

Nonredundant Arrays and Postdetection Processing for Aberration Compensation in Incoherent Imaging* (1971)

For incoherent imaging systems, wave-front aberrations can have the effect of severely reducing the contrast of high spatial frequencies. Although postdetection image processing can improve image detail, the success of such an approach is limited by image noise. If a simple spatial filter consisting of a nonredundant array of clear openings in an opaque mask is placed in the pupil plane of the system, postdetection image processing yields a restored image superior to that obtainable from a system without the pupil-plane filter. Experimental results confirm the predictions of the theory.
Adaptive Zoom Distance Measuring System of Camera Based on the Ranging of Binocular Vision (2012)

Binocular vision ranging, according to the principle of parallax, represents the three dimensional depth in a parallax of 2d image plane. In order to improve the measurement accuracy of the binocular vision ranging, an adaptive zoom distance measuring methodology is focused on in the work. The causes of the error generation during the ranging process and its improvement difficulties are discussed. SIFT (Scale-invariant feature transform) is introduced to obtain parallax. With the samples of focal length acquired through the distance formula, the focal length function about distance is fitted through the least square method. A new distance formula is derived from the focal length function and the distance formula. In addition, a corresponding system is developed to realize the ranging process. To illustrate the procedure of the combination approach, an experiment is conducted with the developed system. The data from the experiment show that this technique can achieve accurate ranging. With the adaptive zoom method, ranging accuracy can reach more than 90%.
Neuropathic Pain Syndromes (2021)

Abstract The International Association for the Study of Pain defines neuropathic pain as pain that is initiated or caused by a lesion or disease affecting the somatosensory system in either the peripheral nervous system or the central nervous system. Several well-recognized descriptors for neuropathic pain suggest a neuropathic rather than nociceptive pathophysiology (hot, burning, painful cold, freezing, prickling or tingling, pins and needles, electrical, shooting, stabbing, lancinating, and itching). However, whether the pain descriptors are used alone or incorporated into questionnaires to identify neuropathic pain, their sensitivity and specificity are limited (generally 70%-85%); therefore, verbal pain descriptors are insufficient for making the diagnosis of neuropathic pain.

Application of Ba[sup 2+]⋅Mg[sup 2+] Co-doped Sr[sub 2]SiO[sub 4]:Eu Yellow Phosphor for White-Light-Emitting Diodes (2005)

Large increases in the efficiency of the yellow phosphor under the excitation range have been achieved by adding the co-doping element ( and ) in the host. In order to apply to white light-emitting diodes (LEDs), we have synthesized a co-doped yellow phosphor and investigated an attempt to develop white LEDs by combining it with an InGaN blue LED chip . Two distinct emission bands from the InGaN-based LED and the co-doped phosphor are clearly observed at 460 and at , respectively. These two emission bands combine to give a spectrum that appears white to the naked eye.
Correction: Finite Element Study of the Mechanical Response in Spinal Cord during the Thoracolumbar Burst Fracture (2012)

Background: The mechanical response of the spinal cord during burst fracture was seldom quantitatively addressed and only few studies look into the internal strain of the white and grey matters within the spinal cord during thoracolumbar burst fracture (TLBF). The aim of the study is to investigate the mechanical response of the spinal cord during TLBF and correlate the percent canal compromise (PCC) with the strain in the spinal cord.
Viewing-Zone Control of Large Full-Color LED Display for 3-D and Digital Signage (2009)

We propose methods to control viewing zones of large screen consisted of full-color LED panel. Large parallax barriers have been developed for public 3-D display. By changing pixel arrangements, locations and number of perspectives can be reconstructed. Response of viewer's position caused by a shift of viewing was detected to evaluate the design of stereoscopic viewing zone. Furthermore, an array of slits has been utilized to provide multiple image s depending on viewers' distances for use of digital signage.
Flavones and flavonols play distinct critical roles during nodulation of <i>Medicago truncatula</i> by <i>Sinorhizobium meliloti</i> (2008)

Flavonoids play critical roles in legume-rhizobium symbiosis. However, the role of individual flavonoid compounds in this process has not yet been clearly established. We silenced different flavonoid-biosynthesis enzymes to generate transgenic Medicago truncatula roots with different flavonoid profiles. Silencing of chalcone synthase, the key entry-point enzyme for flavonoid biosynthesis led to flavonoid-deficient roots. Silencing of isoflavone synthase and flavone synthase led to roots deficient for a subset of flavonoids, isoflavonoids (formononetin and biochanin A) and flavones (7,4'-dihydroxyflavone), respectively. When tested for nodulation by Sinorhizobium meliloti, flavonoid-deficient roots had a near complete loss of nodulation, whereas flavone-deficient roots had reduced nodulation. Isoflavone-deficient roots nodulated normally, suggesting that isoflavones might not play a critical role in M. truncatula nodulation, even though they are the most abundant root flavonoids. Supplementation of flavone-deficient roots with 7, 4'-dihydroxyflavone, a major inducer of S. meliloti nod genes, completely restored nodulation. However, the same treatment did not restore nodulation in flavonoid-deficient roots, suggesting that other non-nod gene-inducing flavonoid compounds are also critical to nodulation. Supplementation of roots with the flavonol kaempferol (an inhibitor of auxin transport), in combination with the use of flavone pre-treated S. meliloti cells, completely restored nodulation in flavonoid-deficient roots. In addition, S. meliloti cells constitutively producing Nod factors were able to nodulate flavone-deficient roots, but not flavonoid-deficient roots. These observations indicated that flavones might act as internal inducers of rhizobial nod genes, and that flavonols might act as auxin transport regulators during nodulation. Both these roles of flavonoids appear critical for symbiosis in M. truncatula.
