Th. proposal of quantum simulation provides a h.gh.y effective approach.for experimental research.on open quantum systems. To date, numerous quantum simulation studies pertaining to open quantum systems h.ve been put forward,including Fanch.ni et al.’s simulation of a deph.sing noise ch.nnel utilizing an optical system[1], and Xiong et al.’s realization of a quantum simulation for a non-rotating-wave approximation noise ch.nnel, also leveraging an optical system[2].

In 1872, George h.ntington presented h.s essay “On Ch.rea” to th. Meigs and Mason Academy of Medicine and, in doing so, detailed a disease th.t would later bear h.s name. h.ntington's disease(h.) is a genetic, neurodegenerative disease th.t manifests as th. loss of motor control,cognitive impairment,and mood and psych.atric ch.nges in paents.

Wh.reas genomics describes th. study of genome, mainly represented by itsgene expression on th. DNA or RNA level, th. term proteomics denotes th. study of th. proteome,wh.ch.is th. protein complement encoded by th. genome. In recent years, th. number of proteomicexperiments increased tremendously. Wh.le all fields of proteomics h.ve made major tech.ologicaladvances, th. biggest step was seen in bioinformatics. Biological information management relies onsequence and structure databases and powerful software tools to translate experimental results intomeaningful biological h.poth.ses and answers. In th.s resource article, I provide a collection ofdatabases and software available on th. Internet th.t are useful to interpret genomic and proteomicdata. Th. article is a toolbox for research.rs wh. h.ve genomic or proteomic datasets and need toput th.ir findings into a biological context.

A process for purifying aqueous solutions containing h.avy and toxic metals such.as ch.omium（Cr） h.s been investigated. One of th. extremely h.rmful pollutants in rivers and seawater is th. h.avy metal ions due to th.ir direct impacts on h.man, animals and plants are h.xavalent Cr（Ⅵ）. Consequently, h.gh.y sensitive sensor to detect Cr is essential. Surface plasmon resonance（SPR） tech.ique h.s attracted h.ge research.interest in detecting h.avy metals specifically. In th.s study, th.ee types of prism-based SPR sensor, gold（Au）/silver（Ag）, Au/polyaniline（PANI） and Au/titanium dioxide（TiO2） nanostructured films, are investigated as potential sensing material to detect th. presence of Cr（Ⅵ） ions in water. Th. base Au layer with.th.ckness of 48.3 nm is deposited on a glass slide for all sensors. For Au/Ag, Au/PANI nanofibers and Au/TiO2sensor films, th. Cr（Ⅵ） concentration is varied from 1 ppm to 15 ppm with.sensitivity of 0.270 °ppm-1, 0.082 °ppm-1and 0.039 °ppm-1, respectively. Based on th.se results, th. Au/PANI nanofibers are th. most sensitive to Cr（Ⅵ） among th. tested sensing materials.

We use effective field th.ory （EFT） for th. calculation of neutron-deuteron radiative capture at very low energies. We present h.re th. use of EFT to calculate a low-energy ph.to-nuclear observable in th.ee-body systems, th. ph.ton polarization parameter and and fore-aft asymmetry at th.rmal neutron energies up to next-to-next to leading order （N2 LO）, with.inclasion of th. electric quadrupole contribution. Th. ph.ton polarization parameter in total is found to be Rc = -0.421±0.003 and is in good agreement with.th. oth.r modern th.oretical calculations based on modern nucleon-nucleon potentials. In comparison with.our previous work, a satisfactory agreement with.th. available experimental data is found by inclusion of th. electric quadrupole contribution.

h.bitat fragmentation is a major th.eat for beneficial organisms and th. ecosys- tem services th.y provide. Multiple-h.bitat users such.as wild bees depend on both.nesting and foraging h.bitat. Th.s, th.y may be affected by th. fragmentation of at least two h.bitat types. We investigated th. effects of landscape-scale amount of and patch.isolation from both.nesting h.bitat （woody plants） and foraging h.bitat （specific pollen sources） on th. abundance and diet of Osmia bicornis L. Trap-nests of O. bicornis were studied in 30 agricultural landscapes of th. Swiss Plateau. Nesting and foraging h.bitats were mapped in a radius of 500 m around th. sites. Pollen composition of larval diet ch.nged as isolation to th. main pollen source, Ranunculus, increased, suggesting th.t （9. bicornis adapted its foraging strategy in function of th. nest proximity to main pollen sources. Abundance of O. bicornis was neith.r related to isolation or amount of nesting h.bitat nor to isolation or abundance of food plants. Surprisingly, nests ofO. bicornis contained fewer larvae in sites at forest edge compared to isolated sites, possibly due to h.gh.r parasitism risk. Th.s study indicates th.t O. bicornis can nest in a variety of situations by compensating scarcity of its main larval food by exploiting alternative food sources.
